🏢 Who We Are

Calorie Log is developed and maintained by Nocturnal Devs.

🔒 Local-First Storage

Calorie Log primarily stores your information on your device. The app does not require a separate account to use core features.

Information stored locally can include:

• Meals, favorites, notes, tags, and nutrition history
• Profile data such as weight, height, age, activity level, and goals
• Meal photos and analysis results saved in the app
• Theme, barcode, quota, and subscription state used by the app interface
• JSON backup files that you export or import manually

🌐 When Data Leaves Your Device

Some features rely on third-party services. When you use those features, limited data may be sent to external providers:

• AI analysis: meal photos, typed descriptions, and related request data may be sent to the configured AI endpoint to return nutrition estimates. The app ships with a default endpoint, and users may change that endpoint in settings.
• Barcode lookup: scanned barcode values are sent to Open Food Facts to retrieve product and nutrition information.
• Optional location hint: if you enable location-assisted barcode lookups, the app requests your device location and may call BigDataCloud to derive a country code used to improve Open Food Facts results.
• Analytics: the app uses Firebase Analytics to record usage and stability events such as app launches, screen actions, and feature flows.
• Advertising: the free tier may display banner, native, or rewarded ads through Google Mobile Ads and Meta Audience Network mediation. Those providers may process device and ad request data under their own privacy terms.
• Subscriptions: in-app subscription purchases are processed by Apple. Billing, renewals, and subscription management are handled through your Apple account.

📤 Exports, Imports, and Sharing

Calorie Log lets you export your data as JSON and import that data back into the app.

• Exported backup files are created only when you choose to export.
• If you share an export file, it will be shared through the destination you choose.
• Imported files are read from the location you choose and merged into local app storage.

🗑️ Retention and Deletion

You remain in control of the data stored locally in the app.

• You can delete meals, clear data, or reset the app from within Calorie Log.
• Uninstalling the app removes locally stored app data from that device.
• The app may automatically remove older local content to control storage use, including clearing old non-favorite meal images after about 2 months and deleting older meals after about 6 months.
• The app also enforces local storage limits, such as capping favorites and trimming older non-favorite content when needed.

⚙️ Your Choices

• You can use the app without creating an account.
• You can toggle location-assisted barcode lookups on or off in settings.
• You can choose whether to use the default AI endpoint or a custom one.
• You can manage or cancel subscriptions through your Apple subscription settings.
• You can export, import, or delete your local data at any time.

👶 Children's Privacy

Calorie Log is not directed to children under 13. If you believe a child has provided personal information through the app or through support channels, contact us and we will review the request.

🛡️ Security

Because Calorie Log stores most information locally, your device's own protections such as passcodes, biometrics, encryption, and backup settings play an important role in protecting your data.

Third-party providers used for analytics, ads, AI analysis, barcode lookup, location-derived country hints, and subscriptions operate under their own security and privacy practices.

📝 Changes to This Policy

We may update this Privacy Policy as the app changes. Any updates will be reflected by revising the date at the top of this page.
