Terms of use

Effective date: October 25, 2026

These terms cover your use of the Chalkmark app and this website. By using them you agree to these terms.

Using Chalkmark

Chalkmark is a personal workout log with a training coach. You may use it for your own training. Do not misuse it, attempt to break it or use it to harm others.

Health disclaimer

Chalkmark and Chalk give general fitness information. They are not medical advice and are not a substitute for a doctor, physical therapist or other qualified professional. Talk to a qualified professional before starting or changing a training program, especially if you have an injury, a health condition, or take medication. Stop immediately if something hurts or you feel unwell, and do not train through pain. If you think you have a medical emergency, contact your local emergency services.

Suggestions about load, reps, sets and rest are estimates from a rule-based engine and your own history. You are responsible for choosing weights and exercises that are safe for you.

Your data

You own your training data. Chalkmark stores it on your iPhone. Keep your own backups; we cannot recover data from a phone we never received it from. See the privacy policy for details.

Beta software

Chalkmark may be offered as a beta. Beta versions can contain bugs and change without notice.

Provided as is

The app and website are provided “as is” and “as available”, without warranties of any kind, to the extent allowed by law. We do not promise that they will be error-free, uninterrupted, or that coaching suggestions will fit you.

Limitation of liability

To the extent allowed by law, we are not liable for indirect or consequential damages, loss of data, or injury arising from your use of the app. Nothing here limits rights you have by law that cannot be limited.

Changes

We may update these terms. We will change the effective date above, and for material changes tell you in the app.
