4. AI Processing of Journal Entries

When you submit a reflection or trigger pattern analysis, the text of your journal entry is sent to Google (Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA) via the Gemini API for the purpose of generating an AI response. This is the core service you signed up for.

Important: Your journal entry text is transmitted to Google's servers (Gemini API) to generate your response. We do not store your entries on our own servers — they are saved only locally on your device. Google processes this data under its API data processing agreement. As of the effective date of this policy, Google does not use API-submitted content to train its models by default.

We encourage you to avoid entering data that could identify third parties (e.g. full names of other people) in your reflections unless necessary for your personal journaling purpose.

5. Third-Party Service Providers

We use the following third-party processors who may receive your data:

Service Purpose Data shared Privacy Policy
Google (Gemini API) AI reflection analysis Journal entry text (sent on-demand) policies.google.com/privacy
RevenueCat Subscription management Pseudonymous user ID, subscription status, purchase events revenuecat.com/privacy
PostHog Analytics & A/B testing Pseudonymous event data, device identifiers posthog.com/privacy
Google Play App distribution & payment Purchase data (handled by Google) policies.google.com/privacy
Expo (Expo Inc.) Push notification delivery Notification token (if you enable reminders) expo.dev/privacy

All third-party processors are contractually bound to process your data only as instructed and in compliance with GDPR where applicable.

6. International Data Transfers

Some of our service providers (including Google, RevenueCat, and PostHog) are based in the United States. Where data is transferred outside the European Economic Area (EEA), we ensure appropriate safeguards are in place, including Standard Contractual Clauses (SCCs) approved by the European Commission, or reliance on an adequacy decision.

7. Data Retention

8. Your Rights Under GDPR

You have the following rights regarding your personal data:

To exercise any of these rights, contact us at: strehldevs@gmail.com

We will respond to requests within 30 days. You also have the right to lodge a complaint with a supervisory authority. In Germany, you may contact the data protection authority relevant to your federal state, or the Bundesbeauftragte für den Datenschutz und die Informationsfreiheit (BfDI).

9. Data Security

We take reasonable technical and organisational measures to protect your data. Journal entries are stored only on your device using AsyncStorage and, for sensitive data like your PIN, using Expo Secure Store (backed by the device's secure enclave / Keystore). Network transmissions to Google (Gemini API) and other services are made over encrypted HTTPS connections.

However, no method of transmission over the internet is 100% secure. You are responsible for keeping your device secure and enabling app lock if you are concerned about third-party access to your journal.

10. Children's Privacy

Clarity Journal is intended for users aged 16 and over. We do not knowingly collect personal data from children under 16. If you become aware that a child has provided us with personal data, please contact us and we will take steps to delete it.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of the app after changes constitute acceptance of the updated policy.
