Terms of Service

Last updated: May 4, 2026

TL;DR: NimbleCal provides a privacy-first calendar service with free and paid plans. You are responsible for your account, your encryption keys, and your lawful use of the Service. We process paid subscriptions through Paddle, which acts as our merchant of record and authorized reseller. We do not run ads or cross-site tracking, sell your personal data or User Content, share that data or User Content for cross-context behavioral advertising or targeted advertising, build advertising profiles from that data or User Content, or use that data or User Content to train AI models.

This TL;DR is a convenience summary and does not replace the Terms below, which contain the complete details.

1. Acceptance of Terms

By accessing or using NimbleCal's website (the "Website"), web application (the "Web App"), or related services (collectively, the "Service"), operated by Nimbledot LLC, a Wyoming limited liability company ("Company", "we", "us", or "our"), you ("User", "you", or "your") agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you must not access or use the Service.

By creating an account, accessing, or using the Service, you also acknowledge that you have read the NimbleCal Privacy Policy. The Privacy Policy describes how we handle personal data. If there is a conflict between these Terms and the Privacy Policy, these Terms govern the contractual relationship, while the Privacy Policy governs how we handle personal data.

If you are using the Service on behalf of an organization, you represent and warrant that you have authority to bind that organization to these Terms, and "you" also refers to that organization.

2. Description of the Service

NimbleCal is a privacy-first calendar service currently offered through the Website and Web App.

The Service allows you to create, manage, and share calendar events. Calendar content you save in the app is end-to-end encrypted by default, encrypted on your devices before storage or sync, and protected by keys that do not leave your devices in plaintext. Certain limited surfaces must be processed outside the end-to-end encrypted path so specific features, such as invitations, reminders, billing, and support, can work properly and reliably. Those exceptions are described in Section 8 and in the Privacy Policy.

The Service is offered on a freemium basis, with free and paid subscription tiers as described in Section 11 (Subscription Plans and Billing).

We may add, modify, remove, or discontinue features, integrations, or supported platforms over time.

3. Eligibility

3.1 Minimum Age

You must be at least 13 years of age to use the Service. If you are between 13 and 18 years of age (or the age of majority in your jurisdiction, whichever is higher), you may only use the Service with the consent of a parent or legal guardian, and your parent or legal guardian must agree to these Terms on your behalf.

3.2 Children under 13

NimbleCal is not directed to children under 13, and we do not knowingly permit children under 13 to create accounts.

3.3 Jurisdiction-Specific Age Requirements

If you are located in a jurisdiction that requires a higher minimum age for the use of online services without parental consent, you must meet that jurisdiction's requirement or have the consent required by applicable law.

3.4 Capacity

By using the Service, you represent and warrant that you have the legal capacity to enter into a binding agreement (or that your parent or legal guardian has agreed on your behalf).

4. Account Registration and Security

4.1 Account Creation

To use account-based features of the Service, you must create an account by providing a valid email address and completing the authentication process. You agree to provide accurate and current information during registration.

4.2 Account Security

You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You agree to immediately notify us of any unauthorized use of your account.

4.3 Encryption Key Responsibility

Because NimbleCal uses end-to-end encryption, your encryption keys are essential to accessing your data.

We do not hold your decryption keys in plaintext and therefore cannot recover encrypted calendar content for you.

You acknowledge that:

• you are solely responsible for safeguarding your encryption keys and any recovery mechanisms provided
• if you lose your encryption keys, your encrypted data may be permanently inaccessible, and we will have no ability to recover it
• we bear no liability for data loss resulting from lost encryption keys

4.4 Individual Account Use

Each account is intended for use by one individual. You may not share your account credentials with others or allow others to access the Service through your account.

5. Acceptable Use Policy

5.1 Permitted Uses

You may use the Service only for lawful purposes and in accordance with these Terms. The Service is intended for personal and organizational calendar management.

5.2 Prohibited Conduct

You agree not to:

• (a) Use the Service for any illegal purpose or in violation of any applicable law or regulation;
• (b) Use the Service to store, transmit, or distribute any content that is unlawful, harmful, threatening, abusive, harassing, defamatory, obscene, or otherwise objectionable;
• (c) Infringe or misappropriate the intellectual property, privacy, or other rights of others;
• (d) Attempt to gain unauthorized access to any part of the Service, other user accounts, or any systems or networks connected to the Service;

• (h) Use the Service to send spam, bulk communications, or unsolicited messages;
• (i) Impersonate any person or entity or misrepresent your affiliation with any person or entity;
• (j) Circumvent, disable, or otherwise interfere with any security-related features of the Service, including encryption mechanisms;
• (k) Use the Service in any manner that could overload, damage, or impair the Service or interfere with any other party's use of the Service;
• (l) Create or use multiple accounts to evade plan limits, subscription fees, usage restrictions, security controls, or enforcement actions;
• (m) Upload, transmit, distribute, or store malware, viruses, harmful code, or content intended to compromise systems, networks, or data;
• (n) Use the Service to exploit or harm minors, including by creating, storing, transmitting, or distributing child sexual abuse material;
• (o) Use the Service to promote or support terrorism, violent extremism, or credible threats of violence;
• (p) Use the Service for targeted harassment; or
• (q) Use the Service in violation of applicable sanctions, export-control, or trade-compliance laws.

5.3 Enforcement

We reserve the right to investigate and take appropriate action against any violation of this section, including, without limitation, suspending or terminating your account and reporting violations to law enforcement authorities where appropriate.

6. User Content and Data Ownership

6.1 User Content

You retain all ownership rights in the calendar data and other content you submit, upload, create, transmit, or store through the Service ("User Content"). We claim no ownership over your User Content.

6.2 Limited License to Operate the Service

By using the Service, you grant us and our service providers a limited, worldwide, non-exclusive, royalty-free license to host, process, transmit, and store your User Content solely as necessary to provide and maintain the Service.

Due to our end-to-end encryption architecture, this processing is primarily limited to storing encrypted data and transmitting it to your authorized devices and, where applicable, to recipients or invitees you designate through the Service's sharing and invitation flows.

You acknowledge that certain limited elements of your User Content and related data may be processed in unencrypted form as described in Section 8, including invitation records and other operational data necessary for reminders, billing, support, and similar service functions. For those elements, you grant us and our service providers the limited right to process them solely for those purposes.

6.3 Your Responsibility for Others' Data

You are responsible for ensuring you have the necessary rights and legal authority, including any required notices, consents, or other lawful basis, to upload, share, and use your User Content in the Service, especially if it contains personal data about another person or sensitive data.

6.4 Regulated Compliance Workloads

Unless we have entered into a separate written agreement that expressly covers the use case, you may not use the Service to process data that requires Nimbledot LLC to comply with a specialized legal or regulatory framework, such as HIPAA, GLBA, or PCI DSS.

This section does not prohibit ordinary calendar entries that may incidentally include personal or sensitive context. It is intended to avoid using the Service as a regulated compliance system where specialized obligations would apply to us.

6.5 No Monetization of User Data

We do not sell your personal data or User Content.

We do not share your personal data or User Content for cross-context behavioral advertising or targeted advertising.

We do not use your personal data or User Content to build advertising profiles.

We do not use your personal data or User Content to train AI models.

6.6 Data Portability and Exports

You may export your User Content through the features provided in the Service, subject to feature availability and reasonable technical limits.

7. Intellectual Property

7.1 Company IP

The Service, including its design, features, functionality, source code, documentation, trademarks, logos, and all related intellectual property, is and remains the exclusive property of Nimbledot LLC and its licensors and is protected by intellectual property laws. These Terms do not grant you any right, title, or interest in our intellectual property except for the limited right to use the Service in accordance with these Terms.

7.2 Feedback and Testimonials

If you submit feedback, ideas, or testimonials, you grant us a non-exclusive, worldwide, royalty-free, perpetual license to use, modify, and incorporate them to operate, improve, and promote the Service, without any obligation or compensation to you.

If you choose to allow a public quote for a testimonial, you give us permission to display that testimonial on NimbleCal-owned channels with the attribution you choose to provide, or anonymously if you prefer. If you later ask us to remove a published testimonial, we will make reasonable efforts to remove it from channels we control.

7.3 Open Source Components

The Service may include open source software components, each of which is licensed under its respective open source license. Nothing in these Terms limits your rights under, or grants you rights that supersede, any applicable open source license.

8. Encryption and Data Handling

8.1 End-to-End Encryption

NimbleCal employs end-to-end encryption by default for calendar content you save in the app. Event titles, descriptions, notes, locations, recurrence details, and similar calendar content are encrypted on your devices before they are synced or stored on our servers.

For encrypted calendar records you store or sync in the app, the servers store ciphertext plus the limited metadata needed to sync and maintain those records.

For that end-to-end encrypted calendar storage and sync model, Nimbledot LLC does not hold the keys needed to decrypt your encrypted event content and does not read it in plaintext.

8.2 Exceptions to End-to-End Encryption

You acknowledge and agree that certain data must be processed outside the scope of end-to-end encryption so specific Service features can work properly and reliably:

(a) Invitations and Email Delivery: When you choose to send an invite, recipient email addresses are needed for delivery, and the event details in the invitation must be readable by recipients and email systems. For that flow, NimbleCal stores and processes recipient email addresses and an invitation record that can include the event title, description, start and end time, timezone, location, organizer name and email, optional organizer message, invitation links or tokens, RSVP-page data, related delivery metadata, and an iCalendar file for calendar clients. Invitation emails for this flow are processed by our email delivery provider.

(b) Reminder Timestamps: To deliver reminders, the Service maintains reminder timestamps and related scheduling metadata, such as the date and time a reminder should be sent, in a separate path that is intentionally not end-to-end encrypted. This metadata is designed not to include plaintext event titles, descriptions, notes, locations, or other calendar content.

(c) Account Information, Billing, and Support Data: Authentication, subscription, billing, direct-contact, and feedback features require processing certain personal data outside end-to-end encryption when you use those features, such as email addresses, authentication records, subscription metadata, refund records, and support or feedback message content.

(d) Metadata: Certain technical metadata, such as internal identifiers, deletion or visibility flags, and sync timestamps, may be processed in unencrypted form to maintain the Service. For encrypted calendar records you store or sync in the app, this metadata does not include your event titles, descriptions, or other calendar text.

(e) Operational Diagnostics and Website Analytics: If crash reports are enabled in the Web App, NimbleCal sends a narrow, predefined operational crash payload through its own server path before anything reaches Sentry. The Web App does not send launch-scope crash reports directly to Sentry, and the current launch posture does not include product analytics or user-content analytics in the Web App. The Website uses Plausible for cookie-free aggregate pageview analytics and limited Website click-event labels, such as CTA, checkout, or support-link clicks. That Website analytics path is separate from the Web App and from the end-to-end encrypted calendar-content model.

8.3 No Guarantee of Absolute Security

While we use well-vetted, widely adopted cryptographic primitives and other security measures, no system is perfectly secure. We cannot guarantee that unauthorized third parties will never be able to circumvent our security measures.

9. Third-Party Services

9.1 Third-Party Service Providers

The Service relies on third-party service providers for certain functionality, such as hosting, authentication, database services, billing, email delivery, abuse protection, diagnostics, Website analytics, and support communications.

These providers may process certain data as described in Section 8 and in the Privacy Policy.

Service-provider details may change as the Service evolves. The Privacy Policy and Service providers and subprocessors page describe the current service providers, data-handling posture, and change-notice approach in more detail.

9.2 Third-Party Terms and Policies

Your use of certain third-party services may also be subject to those providers' own terms and privacy policies. We do not control those providers when they act under their own terms.

9.3 Future Integrations

We may offer integrations with third-party services in the future. If we do, additional terms or disclosures may apply.

10. Service Availability and Modifications

10.1 Availability

We strive to maintain the availability of the Service but do not guarantee uninterrupted or error-free access.

The Service may be temporarily unavailable due to maintenance, updates, security work, or circumstances beyond our control.

10.2 Modifications to the Service

We reserve the right to modify, update, suspend, or discontinue all or part of the Service at any time.

If we discontinue the Service entirely, we will make commercially reasonable efforts to provide advance notice and a reasonable opportunity to export your data.

10.3 No Service Level Agreement

Unless you have a separate written agreement with us that includes a service level agreement ("SLA"), these Terms do not guarantee any specific uptime, performance level, or response time.

10.4 Beta and Experimental Features

We may offer features identified as beta, preview, early access, experimental, or with similar labels.

Beta and experimental features may be incomplete, unavailable, changed, or discontinued at any time. They may contain errors, cause unexpected behavior, or result in data loss.

Unless we state otherwise in writing, beta and experimental features are provided for evaluation on an "as is" and "as available" basis, without any SLA or warranty, and are subject to these Terms and any additional terms or notices we provide. You should not rely on beta or experimental features for critical workflows.

11. Subscription Plans and Billing

11.1 Free and Paid Plans

NimbleCal may offer free and paid subscription tiers. Paid tiers generally provide higher usage limits and additional features. Current plan details are described in the Web App or on the Website at the time of purchase.

We may change plan features, limits, promotional terms, or pricing over time.

11.2 Payment Processing via Paddle

Paid subscriptions are processed through Paddle, which acts as NimbleCal's merchant of record and authorized reseller for paid subscription orders, and its payment partners.

When you start a paid subscription:

• you authorize Paddle and its payment processors to charge the payment method you provide for the applicable subscription price, taxes, and any other charges disclosed at checkout
• Paddle and its processors handle your payment method details; we do not store your full card number or bank account information on our own servers
• we may receive subscription and billing metadata from Paddle to determine your access level and manage your subscription

11.3 Billing, Renewal, and Cancellation

Subscriptions are typically billed in advance on a recurring basis, depending on the plan you choose.

Unless otherwise stated:

• your subscription automatically renews at the end of each billing period until you cancel
• you may cancel at any time
• cancellation takes effect at the end of the current billing period, and you retain access to paid features until then

If a payment cannot be processed, we may retry the charge, ask you to update your payment method, downgrade your account to a free tier, or suspend access to paid features.

11.4 Refunds

Refunds are governed by our Refund Policy.

NimbleCal currently offers a 30-day money-back guarantee on your first payment, no questions asked, as described in that policy.

11.5 Price Changes

We may change subscription pricing in the future. If a price change affects future renewals of your current plan, we will provide reasonable advance notice before the new pricing takes effect.

Your continued use of the paid Service after the price change takes effect constitutes acceptance of the new pricing. If you do not agree to the new pricing, you may cancel before the change takes effect.

12. Termination

12.1 Termination by You

You may stop using the Service at any time. You may also delete your account through the in-Service deletion flow where available, or otherwise request deletion as described in the Privacy Policy.

12.2 Suspension or Termination by Us

We may suspend or terminate your access to the Service, or any portion of it, if:

• you materially breach these Terms
• we are required to do so by law or valid legal process
• we reasonably believe your use of the Service poses security, abuse, fraud, or operational risk to the Service or other users

If we terminate your account without cause and you have a paid subscription, we will make reasonable efforts to provide any refund required by law or by our then-current refund commitments.

12.3 Effect of Termination

Upon termination, your right to use the Service ends immediately.

12.4 Data Deletion and Retention

After account termination or deletion, data handling, deletion, and retention are governed by the Privacy Policy and the technical and legal limits described there. This can include limited retention in backups, billing records, and suppression records where technically necessary or required by law.

12.5 Survival

The following provisions survive termination to the extent necessary to give effect to their purpose:

• Content and data obligations: Sections 6.1 (User Content), 6.3 (Your Responsibility for Others' Data), and 6.5 (No Monetization of User Data)
• Ownership, disclaimers, and liability protections: Sections 7 (Intellectual Property), 13 (Disclaimers), 14 (Limitation of Liability), and 15 (Indemnification)
• Dispute, governing-law, and general terms: Sections 16 (Dispute Resolution), 17 (Governing Law), and 18 (General Provisions)

The following provisions survive only in limited scope:

• Section 6.2 (Limited License to Operate the Service) survives only for User Content retained as described in Section 12.4 and the Privacy Policy.
• Section 6.4 (Regulated Compliance Workloads) survives only with respect to your use of the Service before termination.

Section 6.6 (Data Portability and Exports) does not survive termination.

13. Disclaimers

13.1 "As Is" and "As Available"

THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

13.2 No Warranty of Accuracy

WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. WE DO NOT WARRANT THE ACCURACY, COMPLETENESS, OR RELIABILITY OF ANY CONTENT OR INFORMATION OBTAINED THROUGH THE SERVICE.

13.3 Encryption Disclaimer

BECAUSE OF THE END-TO-END ENCRYPTION MODEL, CERTAIN SUPPORT ACTIONS ARE TECHNICALLY IMPOSSIBLE FOR US, INCLUDING RECOVERING ENCRYPTED CALENDAR CONTENT WITHOUT THE NECESSARY KEYS OR CREDENTIALS. YOU ACKNOWLEDGE THAT THIS LIMITATION IS PART OF THE SERVICE DESIGN.

13.4 No Emergency or Safety-Critical Use

THE SERVICE IS NOT DESIGNED OR WARRANTED FOR EMERGENCY, SAFETY-CRITICAL, MEDICAL, LEGAL, FINANCIAL, OR OTHER HIGH-RISK USES WHERE FAILURE, DELAY, OR LOSS OF ACCESS COULD LEAD TO DEATH, PERSONAL INJURY, PROPERTY DAMAGE, LEGAL HARM, OR FINANCIAL LOSS. YOU ARE RESPONSIBLE FOR MAINTAINING INDEPENDENT REMINDERS, BACKUPS, AND WORKFLOWS FOR CRITICAL OBLIGATIONS.

13.5 Jurisdictional Variations

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES. IN SUCH JURISDICTIONS, THE ABOVE EXCLUSIONS APPLY TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW.

14. Limitation of Liability

14.1 Exclusion of Consequential Damages

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NIMBLEDOT LLC, ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, LOSS OF PROFITS, LOSS OF BUSINESS OPPORTUNITIES, OR LOSS OF GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

14.2 Cap on Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL AMOUNT YOU PAID TO US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM; OR (B) ONE HUNDRED U.S. DOLLARS ($100).

14.3 Basis of the Bargain

THE LIMITATIONS IN THIS SECTION REFLECT A FAIR AND REASONABLE ALLOCATION OF RISK BETWEEN YOU AND NIMBLEDOT LLC AND ARE AN ESSENTIAL BASIS OF THE BARGAIN BETWEEN US. THE SERVICE WOULD NOT BE PROVIDED WITHOUT THESE LIMITATIONS.

14.4 Jurisdictional Variations

SOME JURISDICTIONS DO NOT ALLOW LIMITATIONS ON LIABILITY FOR CERTAIN TYPES OF DAMAGES. IN SUCH JURISDICTIONS, OUR LIABILITY IS LIMITED TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW.

15. Indemnification

To the extent permitted by applicable law, you agree to indemnify, defend, and hold harmless Nimbledot LLC, its officers, directors, employees, and agents from and against claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or relating to:

(a) your use of the Service; (b) your violation of these Terms; (c) your violation of applicable law; (d) any User Content you submit, store, or transmit through the Service; or (e) your infringement or violation of a third party's rights.

We may assume the exclusive defense and control of any matter otherwise subject to indemnification by you, in which case you agree to cooperate with our defense.

16. Dispute Resolution

16.1 Informal Resolution

Before initiating any formal dispute resolution, you agree to first contact us at support@nimblecal.com and attempt to resolve the dispute informally for at least 30 days. Most disputes can be resolved without formal proceedings.

16.2 Binding Arbitration

If we cannot resolve a dispute informally, you and Nimbledot LLC agree that any dispute, controversy, or claim arising out of or relating to these Terms or the Service shall be resolved by binding arbitration administered by the American Arbitration Association ("AAA") under the AAA Consumer Arbitration Rules. The arbitration shall be conducted in the English language. The arbitrator's decision shall be final and binding and may be entered as a judgment in any court of competent jurisdiction.

16.3 Class Action Waiver

YOU AND NIMBLEDOT LLC AGREE THAT ANY DISPUTE RESOLUTION PROCEEDINGS WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. YOU WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION LAWSUIT OR CLASS-WIDE ARBITRATION.

16.4 Exceptions to Arbitration

Notwithstanding the above, either party may seek injunctive or equitable relief in any court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of intellectual property rights.

Additionally, either party may bring an individual claim in small-claims court if the claim falls within that court's jurisdiction and remains in that court.

Nothing in this Section 16 limits any right you may have to seek public injunctive relief where that right cannot be waived under applicable law.

16.5 Opt-Out Right

You may opt out of this arbitration agreement by sending written notice to support@nimblecal.com within 30 days of first accepting these Terms. Your notice must include your name, email address associated with your account, and a clear statement that you wish to opt out of the arbitration clause.

16.6 International Users

If you are located outside the United States, you may have the right to bring proceedings in your local courts. Nothing in this section deprives you of mandatory consumer protections under the law of your jurisdiction of residence.

16.7 Arbitration Fees

Arbitration fees and costs will be allocated in accordance with the AAA Consumer Arbitration Rules, the AAA Consumer Arbitration Fee Schedule, and applicable law. Nimbledot LLC will pay any arbitration fees or costs it is required to pay under those rules, that fee schedule, or applicable law.

17. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Wyoming, United States, without regard to its conflict-of-law principles.

For any disputes not subject to arbitration, the exclusive jurisdiction and venue shall be the state and federal courts located in Wyoming.

If you are a consumer resident of the European Economic Area, the United Kingdom, or another jurisdiction with mandatory consumer protection laws, those mandatory protections apply regardless of the governing law chosen here.

18. General Provisions

18.1 Changes to These Terms

We may update these Terms from time to time.

When we make material changes, we will post the updated Terms and update the "Last updated" date. We may also notify you through the Service or by email where appropriate.

Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Service.

18.2 Entire Agreement

These Terms, together with the Refund Policy and any other documents expressly incorporated by reference, constitute the entire agreement between you and Nimbledot LLC regarding the Service and supersede all prior or contemporaneous agreements, representations, or understandings.

18.3 Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court of competent jurisdiction, the remaining provisions shall remain in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable while preserving its original intent.

18.4 Waiver

Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by an authorized representative of Nimbledot LLC.

18.5 Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign our rights and obligations without restriction, including in connection with a merger, acquisition, or sale of assets. Any purported assignment in violation of this section is void.

18.6 Force Majeure

We shall not be liable for any failure or delay in performing our obligations under these Terms caused by events beyond our reasonable control, including but not limited to natural disasters, acts of government, internet outages, cyberattacks, pandemics, or other force majeure events.

18.7 Notices

We may send you notices via the email address associated with your account. You may send notices to us at support@nimblecal.com. Email notices are deemed received 24 hours after sending.

18.8 No Third-Party Beneficiaries

These Terms are for the benefit of you and Nimbledot LLC only. No third party has any rights under these Terms.

18.9 Headings

Section headings are for convenience only and have no legal effect.

19. International Users and Data Transfers

NimbleCal is operated from the United States and is available globally.

If you use the Service from outside the United States, you acknowledge that personal data may be processed in the United States, the European Union, Switzerland, and other countries where our service providers operate, as described in the Privacy Policy.

If you are located in a jurisdiction with mandatory consumer, privacy, or data-protection laws, nothing in these Terms deprives you of protections that cannot be waived under applicable law.
