Privacy Policy
Last updated: June 2026
MindJournal ("we", "our", or "the app") is a private journaling and self-reflection app. Protecting your personal data is our highest priority. This policy explains what data we collect, how we use it, and your rights.
1. Data Stored on Your Device
All journal entries are stored exclusively on your device. Before being saved, every entry is encrypted using AES-GCM with a key that never leaves your device. We cannot access, read, or recover your journal content.
2. Data Transmitted to Our Servers
We transmit data only when you explicitly request an AI reflection. In that case:
- The plain text of the selected journal entry is sent over an encrypted (TLS) connection to our relay server
- The relay server forwards it to an AI provider to generate reflective questions
- The content is not stored, logged, or used for training on our servers
- Only the generated questions are returned to your device and re-encrypted before storage
3. Data We Do Not Collect
- We do not collect your name, email address, or any personally identifiable information
- We do not use analytics SDKs or third-party tracking
- We do not sell or share your data with advertisers
- We do not store your journal content on any server
4. Subscription
Subscription purchases are handled entirely by Apple through the App Store. We do not receive or store your payment information.
5. Crash Reports
If you have opted in to share crash data with developers via Apple's privacy settings, anonymized crash reports may be shared with us through Apple's standard crash reporting system. These reports do not contain journal content.
6. Face ID / Touch ID
Biometric authentication is handled entirely by iOS. MindJournal never accesses or stores biometric data.
7. Children's Privacy
MindJournal is not directed at children under the age of 13. We do not knowingly collect information from children.
8. Wellness and Safety Notice
MindJournal is for journaling and self-reflection only. It does not provide medical advice, diagnosis, therapy, crisis counseling, or emergency services. If you may be in immediate danger, contact local emergency services or a qualified professional.
9. Changes to This Policy
We may update this policy from time to time. Continued use of the app after changes constitutes acceptance of the updated policy.
