Glucera
Privacy Policy
The short version
- Glucera never creates an account or asks for your name, email, or any personal identifier.
- Your glucose readings are stored only in Apple Health on your device — nowhere else.
- No data is sent to Glucera servers. There are no Glucera servers.
- No analytics tools, crash reporters, or advertising SDKs are included.
- Bluetooth is used only to read data from your glucometer. Nothing is logged or transmitted.
- Deleting the app has no effect on your health data. It stays in Apple Health.
1. Data I collect
Glucera does not collect, store, or transmit any personal data to any external server. The app has no backend, no user accounts, and no database of any kind outside of your device.
The only data processed by Glucera is your blood glucose readings, which are read from your glucometer via Bluetooth and written to Apple Health on your device. This processing happens entirely locally.
2. Apple Health
Glucera requests permission to read and write blood glucose data in Apple Health (HealthKit). This data is stored by Apple on your device and, if you have iCloud Health sync enabled, in your personal encrypted iCloud account.
Glucera cannot access any other HealthKit data category. It reads blood glucose only to find where your last sync left off so it can pick up from there — it does not export, analyse remotely, or share this data in any form.
Apple's handling of Health data is governed by Apple's Privacy Policy.
3. Bluetooth
Glucera uses Bluetooth to communicate with your glucometer. It scans for nearby meters and reads the glucose data they broadcast.
No Bluetooth scan data, device identifiers, or communication logs are stored by the app or transmitted externally. Once a reading is written to Apple Health, the raw data is discarded.
Device names you choose to save are stored only in the app's local settings on your device. They are never shared.
4. Widgets and Watch complication
Glucera shares your most recent glucose reading with its home screen widget, lock screen widget, and Apple Watch complication. This happens locally using a standard iOS mechanism for sharing data between an app and its extensions. The data never leaves your device.
5. Notifications
If you grant notification permission, Glucera sends a local notification after each successful sync showing your latest reading. These are local notifications generated on your device — they are not routed through any external push notification service.
6. Third-party services
Glucera contains no third-party analytics, crash reporting, advertising, or social SDKs. It makes no network requests of its own. The only outbound network activity is loading this website and the App Store, which are handled by your browser and iOS respectively — not by the app.
There is no "Send Diagnostics" service that uploads data to a remote server. The diagnostics feature in Settings uses the iOS share sheet to let you review and manually forward a locally generated text report — you decide what to send and to whom.
7. Children's privacy
Glucera does not collect any personal data from any user, including children under 13. Because no data is collected at all, no special provisions for children are required beyond those already covered by this policy.
