Terms of Use

Last updated: October 6, 2026

Using the app

Calister is intended for personal tracking of nutrition, calories, macros, and daily habits. The information in the app is provided for your convenience and does not constitute medical, nutritional, or professional advice.

Account and data

You are responsible for keeping your account details secure. Data you enter, including meals, goals, and weight, is used to power the tracking and personalization experience in the app.

Information accuracy

Calorie, macro, and health data calculations may be estimates only. Please verify important information with an appropriate professional before making health or nutrition decisions.

AI features

Photo, voice and description logging, and the chat, rely on third-party artificial intelligence services. By using these features you agree that the photos, voice recordings, food descriptions and chat messages you share are sent to those services, as described in the Privacy Policy. AI results are estimates and may be inaccurate.

Permitted use

You may not use the app in a way that harms the service, other users, third-party systems, or violates the law. We may restrict use that breaches these terms.

Changes to these terms

These terms may be updated from time to time. Continued use of the app after the terms are updated constitutes acceptance of the updated terms.
