  • Authenticate you and keep your account secure
  • Sync your data across devices when you sign in
  • Process subscriptions and restore purchases
  • Send push notifications you have allowed (with per-category controls in settings)
  • Enforce our Terms of Service and Community Guidelines
  • Respond to support and legal requests
  • Improve reliability and fix bugs

Legal bases (EEA/UK users): contract (providing the Service), legitimate interests (security, product improvement), consent (optional contacts, push notifications where required), and legal obligation.

6. International transfers

We and our processors may store or process data in the United Kingdom, European Union, United States, and other countries. Where required, we rely on appropriate safeguards (such as standard contractual clauses) for transfers outside your country.


7. Retention

We keep your information while your account is active and as needed to provide the Service.

When you delete your account (see Section 9), we delete or anonymise personal data within a reasonable period, except where we must retain data for legal, tax, fraud prevention, or dispute resolution purposes.

Backup copies may persist for a limited time before automatic deletion.


8. Security

We use industry-standard measures including encryption in transit (HTTPS/TLS), access controls, and secure authentication. No method of transmission or storage is 100% secure; we cannot guarantee absolute security.


9. Your choices and rights

In the app

  • Privacy settings — control who sees your shelves and reading updates (Profile → Privacy & profile)
  • Notifications — toggle categories (Profile → Notification settings)
  • Contacts — never required; revoke in iOS/Android system settings
  • Sign out — Profile → Settings → Sign out

Account deletion

To delete your account and associated personal data, email infocovexapps@gmail.com from your registered email with the subject "Delete my Quilld account". We will verify your identity and complete deletion within 30 days, except for data we must retain by law.

Active subscriptions must be cancelled through the App Store or Google Play before or after deletion; deleting the account does not automatically cancel billing.

Rights by region

Depending on where you live, you may have rights to access, correct, delete, restrict, object, port, or withdraw consent. UK/EEA users may complain to their data protection authority. California residents may have rights under the CCPA/CPRA — we do not sell personal information.

To exercise rights, contact infocovexapps@gmail.com. We may need to verify your identity.


10. Third-party links

Quilld may link to book retailers or external sites. We are not responsible for their privacy practices.


11. Changes to this policy

We may update this Privacy Policy from time to time. We will post the new version with a revised "Last updated" date and, for material changes, provide notice in the app or by email where appropriate.
