Privacy Policy

1. Who We Are

ctLibrary™ is published by CozziTech LLC ("CozziTech," "we," "us," or "our"). You can reach us at privacy@cozzitech.com for any privacy question or request, or at support@cozzitech.com for general support.

2. Data Stored on Your Device

All folders, categories, documents, notes, thumbnails, and any optional app-lock password hash live in private app storage on your device. We have no ability to read, copy, transmit, or recover this data.

At-rest protection of that storage is provided by your operating system — specifically, iOS Data Protection (active whenever your device has a passcode set) or Android file-based encryption (active whenever your device has a screen lock set). ctLibrary™ does not implement additional encryption on top of that.

3. Data We Receive

The only personal data we receive is your email address, and only when you choose to verify it. We use it to:

• Send you a one-time 6-digit verification code.
• Send you occasional informational email about CozziTech products, including new features, related apps, important service updates, and security notices.

After verification, the temporary record of the code is deleted from our verification service. Your verified email address is stored on your device in secure storage so the app knows you are verified. Verified email addresses may also be retained by CozziTech for the product-information purposes described above; you can opt out at any time by tapping "Forget my email" in Settings, or by emailing privacy@cozzitech.com.

4. Service Providers

CozziTech uses a small number of vendors solely to deliver the email-verification message that unlocks the full app. These vendors process your email address only to deliver the verification code and may retain transactional log data in accordance with their own privacy policies. They do not have access to the contents of your library.

5. What We Do Not Collect

• No analytics, telemetry, or behavior tracking.
• No advertising identifiers and no advertising.
• No location data.
• No contacts, calendar, microphone, or camera data.
• No content of your documents or notes is ever transmitted off the device.

6. Permissions

ctLibrary™ requests the following device permissions only when needed:

• Files — to let you import documents you select.
• Photo Library — only when you import an image you select.
• Face ID / Touch ID / biometrics — only if you turn on biometric unlock for App Lock.

7. Children

ctLibrary™ is not directed to children under 13 (or under 16 in the EU/UK). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it.

8. Your Rights and Choices

You can exercise the following rights at any time, directly from the app:

• Delete your library — Settings → "Reset & wipe everything" removes all local data.
• Forget your verified email — Settings → "Forget my email" removes the verified email from your device and asks our verification service to delete any pending record.

For access, correction, deletion, or any other privacy request that cannot be completed in-app, contact us at privacy@cozzitech.com. Residents of California, the EU, the UK, and other jurisdictions with applicable privacy laws have rights to access, correct, delete, port, and limit processing of personal data we hold about them.

9. Data Retention

Verification codes are stored only as one-way cryptographic hashes with a short time-to-live (approximately ten minutes) and are deleted automatically — or immediately on successful use. Verified email addresses may be retained for the product-information purposes described in section 3; we honor "Forget my email" and email opt-out requests promptly.

10. Security

All network requests use HTTPS. Verification codes are hashed before storage. If you enable App Lock, your password is stored on your device only as a salted, slow-iteration cryptographic hash — your password itself is never stored or transmitted. At-rest protection of local data is provided by your operating system's built-in file encryption (iOS Data Protection or Android file-based encryption). No method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

11. International Users

The verification service is operated from the United States. By using email verification you consent to your email being processed in the United States and other jurisdictions where our service providers operate.

12. Changes to This Policy

We will update the "Last Updated" date at the top of this page when we change this policy. Material changes will be highlighted in-app on next launch. The current version is always available at cozzitech.com/ct-library-privacy/.
