The short version: DECK stores your cards on your device and syncs them via your private iCloud account. We never see your data. We use anonymized analytics (PostHog, EU) and never sell anything. Payments are handled entirely by Apple — we never see card details.

1. Who We Are

DECK is developed and published by Jamie Newman ("we", "us", "our"). If you have any questions about this policy, contact us at contact@jamie-newman.com.

3. How We Use Your Data

4. Data Storage & Security

All your cards, decks, and event history are stored locally on your device using SwiftData. The App works fully offline without an account.

Sync uses Apple's CloudKit service on your own private iCloud database. Data is transmitted over TLS and stored in your Apple-managed iCloud container. The developer has no access to this data — only you, via your Apple ID, do.

DECK never runs its own backend for your card data. There is no third-party server holding the contents of your deck.

5. On-device intelligence

Pro users with a compatible device see a "What you're avoiding" section in defer analytics that groups high-defer cards into named themes. This clustering runs entirely on-device using Apple's Foundation Models framework. Card content is never transmitted off the device for this purpose, and results are not persisted — the grouping is recomputed each time the view opens.

6. Third-Party Services

The App uses the following third-party services:

Each service operates under its own privacy policy. We encourage you to review their policies.

7. Data Sharing

We do not sell, rent, or share your personal data with third parties for marketing or advertising purposes. Your card data is never shared with anyone — it lives in your private CloudKit database only.

8. Notifications

DECK does not send push notifications. Not for deferred cards returning, not for daily reminders, not for anything. The App is pull, not push. We do not request or use the notification permission.

9. Your Rights & Data Deletion

If you are located in the EEA or UK and have questions about your rights under GDPR, or if you are a California resident with questions about your rights under CCPA, please contact us at the address below. We will respond within 30 days.

10. Children's Privacy

The App is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can delete it.

11. Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the App after changes constitutes acceptance of the updated policy.
