Privacy Policy

Last updated: April 7, 2026

Prick ("the App") is a free glucose monitoring application for iOS. Your privacy matters. Here is exactly what happens with your data.

Data We Collect

None. Prick does not collect, transmit, or store any of your data on external servers. There is no backend, no analytics service, no crash reporting service, and no third-party SDK of any kind.

Data Stored on Your Device

The following data is stored locally on your iPhone:

• Glucose readings (from Bluetooth sync or manual entry)
• Person profiles (names and color preferences)
• Meal records, food tags, and meal events
• Experiment data and results
• App preferences (button position, active profile)

This data never leaves your device except via iCloud sync (see below) or when you explicitly export it.

iCloud Sync

If you have iCloud enabled on your device, your data syncs via Apple's CloudKit infrastructure. This uses Apple's encryption and Apple's servers. The developer has no access to your iCloud data. You can disable iCloud sync for this app in your device's Settings under iCloud.

Bluetooth Data

Prick connects to your glucometer using standard Bluetooth Low Energy (Glucose Profile). The connection is direct between your iPhone and your meter. No data passes through any intermediary server. Bluetooth sync logs are stored locally on your device and can be viewed or deleted in the app's Settings.

Health Data

Prick does not integrate with Apple Health and does not read from or write to the Health app. Your glucose data stays entirely within Prick.

Third-Party Services

None. The app uses no analytics (no Firebase, no Mixpanel, no Amplitude, no Google Analytics), no crash reporting (no Crashlytics, no Sentry), no advertising, and no social media SDKs. The app is built entirely with Apple's native frameworks.

Data Export

You can export your data as JSON or CSV from the app's Settings. When you export, the file is generated locally on your device and shared through the standard iOS share sheet. The developer does not receive a copy of your export.

Children

Prick is not directed at children under 13. We do not knowingly collect information from children.

Changes to This Policy

We may update this policy if the app's data practices change. Any changes will be posted on this page with an updated date. Since the app collects no data, meaningful changes to this policy are unlikely.
