NimbleCal uses end-to-end encryption to keep your calendar private. That means your calendar content is encrypted, and your device needs a key to read it.
Why you might see an "Unlock your encrypted data" prompt
After you sign in (or after a browser restart), NimbleCal may ask you to enter your password again to unlock your encrypted data.
This is normal and intentional:
- Your calendar content stays encrypted at rest.
- NimbleCal only unlocks the decryption key in-memory after you authenticate.
Changing your password safely
If you still know your password, you can reset it safely.
Important: A password reset needs to update encryption keys too. NimbleCal will guide you through this and may ask you to open the reset link on a device where your calendar is already unlocked.
If you forgot your password
Because your calendar content is encrypted end-to-end, NimbleCal cannot recover encrypted event content if you lose the keys needed to decrypt it.
If you cannot unlock NimbleCal on any device, you may need to start fresh.
