Privacy Policy

Last updated: 19 July 2026 (revised)

OsteoSense (“we”, “the app”) helps you track factors related to bone health and produces a daily risk score. This policy explains what data we collect, why, and how it is handled.

Data we collect

How we use it

Your data is used to operate the app: authenticating you, storing your logs, and calculating your scores and history. We do not sell your data or use it for advertising.

AI report — data egress

If you request an AI-generated report, the relevant health inputs needed for that report are sent to Anthropic (our AI provider) to generate the summary. This data leaves our servers for that purpose. Anthropic processes it under their terms and does not use API data to train their models. If you do not request an AI report, no data is sent to Anthropic.

Cookies & local storage

OsteoSense does not use tracking or advertising cookies. The app stores your sign-in session (an access token and your email) in your browser’s local storage, purely so you stay signed in between visits. This data stays on your device and is cleared when you log out.

Storage & security

Data is stored in our own database on a private server. Access is restricted and transport is encrypted (HTTPS). Automated backups are retained for a limited period.

Your choices

You can delete your account and all associated data at any time from Profile → Danger zone → Delete account in the app — this immediately and permanently removes your baseline, logs, and account record. You can also request access to your data, or ask us to delete it on your behalf, by contacting us at the email below.
