2. Purpose of This Policy

This policy describes the processing of personal data when using the PROG mobile app. For information about visiting our website, please refer to our separate Website Privacy Policy.

3. What Data Does PROG Process?

3.1 Local Content Data (on your device only)

Journal entries, goals, tasks, routines, learning progress, and app settings are stored exclusively on your device. There is no server upload, no cloud sync, and no developer access.

3.2 Notifications

PROG can schedule local reminders (notifications) on your device. No push tokens are transmitted and no data is sent to any server.

3.3 Anonymous Referral Analytics (Firebase Analytics)

When you first open the app, you can voluntarily indicate how you heard about PROG (e.g. Instagram, TikTok, or via a creator code). This information is recorded as an anonymized event through Firebase Analytics (Google Ireland Ltd.).

The following data is transmitted:

• Selected referral source (e.g. “instagram”, “tiktok”)

• Creator code (if entered)

• Subscription type upon purchase (e.g. “monthly”, “yearly”, “lifetime”)

NO personal data is collected – no name, no email address, no device ID, no usage behavior. Automatic data collection by Firebase (e.g. screen_view, session_start) is fully disabled.

Purpose: We want to understand which channels and creators bring new users so we can compensate our partners fairly.

Legal basis: Legitimate interest (Art. 6(1)(f) GDPR)

Data processor: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland

3.4 Operating System Diagnostics (optional)

If you have enabled sharing diagnostic data with Apple in your iOS settings, Apple may collect anonymous stability metrics. We do not receive any personal raw data. Apple is solely responsible for this.

No cookies, no advertising IDs, no app tracking. The only external SDK is Firebase Analytics – used exclusively for the anonymous referral analytics described in section 3.3, with automatic data collection disabled.

4. Purposes and Legal Bases

• App features (local storage): Performance of contract (Art. 6(1)(b) GDPR)

• Local notifications: Performance of contract (Art. 6(1)(b) GDPR)

• Anonymous referral analytics: Legitimate interest in evaluating acquisition channels and fair partner compensation (Art. 6(1)(f) GDPR)

• Support contact (email): Processing your inquiry (Art. 6(1)(b) GDPR)

• Apple diagnostics: Apple is responsible; our legitimate interest is limited to anonymized stability information (Art. 6(1)(f) GDPR)

5. Storage Location and Duration

All content data remains on your device until you delete it or uninstall the app. Support emails are retained only as long as necessary for processing and due to legal obligations. Anonymized Firebase events are stored according to Google Analytics standard retention periods (max. 14 months).

6. Recipients / Disclosure

• No disclosure of your app data to third parties

• Firebase Analytics (Google Ireland Ltd.): Processing of anonymized referral events under data processing agreement. Standard contractual clauses are in place. No personal data is shared.

• Support emails are processed by our email provider (data processing agreement)

• No transfer of personal data to third countries through app features

7. Your Rights

Under the GDPR, you have the right to access, rectification, erasure, restriction, data portability, and objection to certain processing activities. You may also lodge a complaint with a data protection supervisory authority (e.g. LfDI Baden-Württemberg, Germany).

8. Use by Children and Minors

The PROG app can generally be used by persons of any age. However, we do not collect personal data via servers and do not perform age verification or profiling. Parents or guardians should ensure that children handle their personal entries responsibly.

9. Security

The app stores data exclusively on your device. Please protect your device (e.g. passcode / Face ID) and use encrypted device backups regularly.

10. Changes

This privacy policy may be updated if features or legal requirements change. The current version is always available at https://prog-app.com/privacy.
