Frequently Asked Questions.

Can TechyDez read my notes?

Absolutely not. QuillFox uses Zero-Knowledge End-to-End Encryption. Your data is encrypted on your device before it ever reaches our servers. Without your master password, your data looks like random gibberish to us.

What happens if I lose my master password?

Because we don't store your master password, we cannot recover it for you. If you lose it, your encrypted data will be unrecoverable. We highly recommend using a password manager.

How does Real-time Collaboration work with E2EE?

When you invite a collaborator to a workspace, QuillFox securely encrypts the workspace's symmetric key using their public key. This ensures only invited users can decrypt and read the workspace contents.

Can I upgrade or downgrade my plan later?

Yes! You can upgrade to Premium or Ultra at any time from the Settings menu. If you downgrade to Free, your extra workspaces will be archived, but you will not lose your data.
