Privacy Policy for Krypnotes

Effective Date: August 2025

1. Our Core Privacy Principle: Zero Knowledge

Krypzon built Krypnotes with your privacy as its highest priority. Our architecture is designed to be zero knowledge, which means we have absolutely no access to the content of your notes, tasks, or other personal information.

2. Information We Do NOT Collect

• Your name, email address, or other contact information.
• The content of your notes, folders, or tasks.
• Your Master Passphrase.
• Your location data.
• Unique device identifiers, except non-personal diagnostics you may choose to send to support.

3. How Your Data is Handled on Your Device

• Note, Folder, and Task Data: Stored in a local database on your device private storage.
• Speech-to-Text: Uses your device operating system speech recognition service when you choose to use dictation.
• Biometric Authentication: Uses your device secure hardware through system APIs. Krypnotes never receives biometric data.
• Encrypted Backups: Backups are encrypted on your device using your Master Passphrase before the backup file is created.

4. Third-Party Services

Krypnotes uses Flutter, Dart, Hive, flutter_quill, speech_to_text, local_auth, and package_info_plus packages to provide app functionality. These packages interface with app or device capabilities and do not transmit your personal note data to Krypzon.

5. Data Security

You are in full control of your data security. Because we operate on a zero-knowledge basis, we cannot help you recover a forgotten Master Passphrase. Losing your Master Passphrase can permanently prevent access to protected notes and encrypted backups.

6. Children's Privacy

Krypnotes is not intended for use by anyone under the age of 13. We do not knowingly collect information from children.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time by posting the updated version on this page.
