Privacy Policy

Last updated: November 1, 2026

Dose Log is built to work entirely on your device. This policy explains what happens to your data — briefly: we don't collect any. Dose Log is developed by Shoumeng Jiaye.

Core principle

We collect almost nothing. · No accounts, no sign-up, no server backend · No analytics or ads — only anonymous crash reports (Sentry) when the app crashes · Records live only in an on-device database

1. Information We Collect

1. Your records (injections, side effects, weight, protein and water intake, notes, settings) are stored only on your device and never uploaded to any server. 2. Dose Log has no account system, so we collect no email, phone number or other identity information. 3. Purchases are handled by the Apple / Google platforms; we only receive a local entitlement confirmation on your device. 4. The only data that leaves your device: anonymous crash reports (stack traces, device model, OS and app version, crash time) sent to Sentry when the app crashes. They contain no record content and are never linked to your identity.

2. How Information Is Used

Data is used solely to present app features on your device. We do not profile, analyze or sell any user data.

3. Storage and Security

All data is stored in a local SQLite database on your device. CSV export creates files you keep yourself; deleting the app deletes all data. There is no copy on any server.

4. Third-Party Services

- In-app purchases: Apple App Store / Google Play Billing (transactions are handled by the platforms under their own privacy policies) - Crash reporting: Sentry (sentry.io) — anonymous crash reports only; no analytics or advertising SDKs

5. Permissions

Notifications are used only for the injection and check-in reminders you configure in the app. You can turn them off at any time in system settings.

6. Data You Choose to Share

Exports and summaries (CSV files, weekly recap, doctor-visit summary) are created on your device and leave it only when you explicitly share them.

7. Deleting Your Data

Delete individual records in the app, or uninstall the app to erase everything. There is no copy on any server.

8. Children

Dose Log is not directed at children and offers no communication features.

9. Changes and Contact

If this policy changes, the new version will be posted on this page with an updated effective date. Questions: tzhh0617@gmail.com
