Privacy Policy

Calometric is designed with privacy as a core principle. We don't collect, store, or transmit any of your personal data. Here's exactly what that means.

No Data Collection

Calometric does not collect any personal information. There are no accounts, no sign-ups, no analytics, no tracking pixels, no crash reporters, and no third-party SDKs. We run no servers of our own, so there is nowhere for us to send your data. The App Store privacy label is Data Not Collected. The only time Calometric contacts the network is to look up a scanned barcode, described below.

Your Health Data

All calorie tracking data, macro information, meal logs, and nutritional goals are stored exclusively on your device. If you use iCloud sync, your data is synced via Apple's CloudKit infrastructure with end-to-end encryption. We never have access to your CloudKit data.

HealthKit Integration

Calometric can read from and write to Apple HealthKit with your explicit permission. HealthKit data is processed entirely on your device and is never transmitted anywhere. You can revoke HealthKit access at any time in Settings → Privacy & Security → Health.

AI Food Recognition

Food recognition uses Apple's on-device Vision and Core ML frameworks to identify foods, and Apple's Foundation Models to estimate portions. All AI processing happens locally on your device. No food descriptions, images, or queries are sent to any external server.

Barcode Scanning

Barcode scanning uses your device's camera to read product codes -- images are never stored or transmitted. To fetch nutrition facts, Calometric sends only the barcode number along with your device's language and country to Open Food Facts, a community-maintained food database. No photos, meal history, or identifying information is included. This is the app's only external network request, and you can add products locally when one is missing or you're offline.

iCloud Sync

If you enable iCloud sync, your data is synced across your Apple devices using Apple's CloudKit. This data is protected by Apple's privacy infrastructure and is associated with your iCloud account, not with us. We cannot access your CloudKit data.

No Third-Party SDKs

Calometric contains zero third-party SDKs. No analytics (no Google Analytics, no Firebase, no Mixpanel). No advertising frameworks. No crash reporting services. Nothing that could collect or leak your data.

Siri & Voice Logging

Voice logging through Siri is processed by Apple's Siri infrastructure according to Apple's privacy policies. Calometric receives only the transcribed text result. We do not record or store audio.

Widgets

Home screen and lock screen widgets display your calorie data locally. No network requests are made by widgets.

Children's Privacy

We do not knowingly collect any data from anyone, including children under 13. Since we collect no data at all, there is nothing to worry about.

Changes to This Policy

If we ever change this policy, we'll update this page. But our commitment to privacy is fundamental to Calometric. We built it this way on purpose.
