Terms of Use

Last updated: October 2026

Ostin is provided by Daniel Baldwin (“we”). By using Ostin you agree to these terms.

Not medical advice

Ostin is a personal record-keeping tool. It records and follows the plan you enter from your prescriber, and shows summaries and estimates of the information you enter. It does not diagnose, treat or recommend doses, and it is not a substitute for professional medical advice. Always follow your prescriber's instructions and check with your doctor before changing your treatment. In an emergency, call your local emergency number.

Estimates

Features such as the estimated medication level and refill forecasts are approximations based on what you enter and published averages. Real values vary between people.

Your data

You are responsible for what you enter and for keeping backups. See the Privacy Policy for how data is handled.

Purchases

Ostin Plus is a one-time in-app purchase processed by Apple under the App Store's terms. Refunds are handled by Apple.

Availability

Ostin is provided “as is”. Features may change. To the extent permitted by law, we aren't liable for damages arising from use of the app.
