Password Protection

Sidvy offers end-to-end encryption for sensitive notes. When enabled, your note content is encrypted before it leaves your device.

How It Works

Section titled “How It Works”
  1. You set a password for a note
  2. The note content is encrypted using that password
  3. Only the encrypted data is stored and synced
  4. You enter the password to decrypt and view

Sidvy never has access to your password or decrypted content.

Encrypting a Note

Section titled “Encrypting a Note”
  1. Open the note you want to protect
  2. Click the lock icon in the toolbar, or use the note menu
  3. Enter a strong password
  4. Confirm the password
  5. Click Encrypt

The note is now encrypted. You’ll see a lock indicator.

Accessing Encrypted Notes

Section titled “Accessing Encrypted Notes”
  1. Click on an encrypted note
  2. Enter your password
  3. The note decrypts and displays
  4. Edit as normal

Password Caching

Section titled “Password Caching”

For convenience, your password is cached in your browser for the session. You won’t need to re-enter it for:

  • The same note (until you close the browser)
  • Other notes using the same password

Important Considerations

Section titled “Important Considerations”

What’s Encrypted

Section titled “What’s Encrypted”
  • Note content (the body text)

What’s NOT Encrypted

Section titled “What’s NOT Encrypted”
  • Note title (so you can find it)
  • Note metadata (created date, etc.)

Encrypted Note Behavior

Section titled “Encrypted Note Behavior”
  • Auto-save is disabled for encrypted notes
  • You must manually save after editing
  • Search does not search encrypted content
  • Wiki links to encrypted notes work, but backlink context is limited

Password Tips

Section titled “Password Tips”

Use Strong Passwords

Section titled “Use Strong Passwords”
  • At least 8 characters
  • Mix of letters, numbers, symbols
  • Not used elsewhere
  • Not easily guessable

Password Manager

Section titled “Password Manager”

Consider using a password manager to:

  • Generate strong passwords
  • Store them securely
  • Access across devices

Same Password Strategy

Section titled “Same Password Strategy”

You can use the same password for multiple notes:

  • Easier to remember
  • Cached password works for all
  • Risk: one password compromises all

Or different passwords:

  • More secure
  • More to remember
  • Each note independently protected
