Symkura ("we", "our", "us") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
1. Core Principle
Symkura is designed with a privacy-first approach. All health data is stored locally on your device and synced encrypted to our own dedicated server in Germany (IONOS, Montabaur). We do not use Supabase Cloud or any US-hosted database. Your data is not subject to the US CLOUD Act. We do not use your health data for advertising, profiling, or sharing with third parties.
2. Data We Collect
Health data: all symptom entries, body map selections, mood ratings, sleep data, medication logs, photos, and notes are stored locally on your device and synced to our server in Germany for cloud storage and cross-device access.
Weather data: if you configure a city in settings, we query the Open-Meteo API (open-meteo.com) to fetch current temperature, humidity, and barometric pressure. Only the city coordinates are sent. No personal identifiers are transmitted.
Purchase data: if you subscribe to Symkura Pro, your purchase is processed by Apple or Google through RevenueCat (revenuecat.com). We receive a pseudonymous user ID and entitlement status. We do not receive your payment details.
3. Anonymous Usage Statistics (Opt-In)
Symkura offers an optional, opt-in anonymous usage statistic. This is disabled by default and only activated if you explicitly consent in the app settings. When enabled, anonymous usage events (e.g. "entry created", "PDF exported") are sent to our server. These events contain no health data, no device identifiers, and no IP addresses. They are linked to a pseudonymous user ID only if you have created an account. You can opt out at any time in the app settings.
4. Apple Health / Google Fit
If you enable the Apple Health or Google Fit integration in the app settings, Symkura reads steps, heart rate, sleep duration, and active minutes from your device's health platform. This data is stored locally on your device only and is never transmitted to our servers. The integration requires your explicit permission and can be disabled at any time.
5. Data We Do Not Collect
Beyond the optional anonymous usage statistics described above, we do not collect device identifiers, IP addresses, location data, or any form of tracking data. There are no third-party analytics or advertising SDKs in Symkura.
6. Data Storage
All data is stored locally on your device and synced to our own dedicated server in Germany. Data is encrypted in transit (TLS) and at rest. Row-level security ensures only you can access your data. If you delete your account, all server data is permanently removed. We recommend using the PDF export feature to save important records independently.
7. Data Sharing
We do not share, sell, or transfer your personal data to any third party. Data that leaves your device: health data sync to our server in Germany, weather city query to Open-Meteo, purchase verification through RevenueCat, and (if opted in) anonymous usage events.
8. Your Rights
You have full control over your data. You can view, export, or delete your data at any time through the app settings. You can delete your account and all associated server data from within the app. No request to us is necessary.

9. Children's Privacy
Symkura is not directed at children under 13. We do not knowingly collect personal data from children under 13.
10. Changes to This Policy
We may update this policy from time to time. We will notify you of significant changes via the app. Continued use of the app after changes constitutes acceptance of the updated policy.
