Privacy Policy
Last updated: September 30, 2026
Calcifer is designed to keep your nutrition data on your device. We do not require an account and we do not collect personal profiles, email addresses, or analytics about how you use the app. The exception is AI estimation, which sends the meal or workout you want estimated to our API.
What data Calcifer stores
Calcifer stores the workouts and meals you enter, along with the calorie, macro, duration, and goal information needed to provide the app's tracking features. This information is stored locally on your device.
AI estimate requests
When you use AI-powered meal or workout estimation, Calcifer sends the title and description of that single meal or workout to the Calcifer API. It sends nothing else from your log, goals, or history.
The Calcifer API forwards that text to TypeSafe. TypeSafe's AI model produces the estimate, and the Calcifer API returns it to the app. TypeSafe processes these requests under its own terms and privacy policy.
The Calcifer API does not store or log the meals and workouts it receives. It briefly keeps your IP address in memory to enforce rate limits, and discards it once those limits reset.
What we do not collect
- No name, email address, or account information
- No location, contacts, photos, or device identifiers
- No advertising profiles or usage analytics
- No stored workouts or meals on Calcifer-operated servers
Your choices
You can edit or delete your meals and workouts within the app. You can also remove Calcifer's locally stored data by clearing the app's data or uninstalling the app. You can avoid sending anything to the Calcifer API by entering calories and macros manually instead of using AI estimation.
Changes to this policy
If Calcifer's data practices change, this page will be updated with the revised policy and date.
