Terms of use

Last updated November 7, 2026. ClassStamp is made by Taylor O'Neal, Purafield Studio, Austin, Texas ("we").

These terms add to Apple's standard Licensed Application End User License Agreement, which applies to ClassStamp. If they conflict, Apple's agreement controls for anything Apple requires.

1. What ClassStamp does

ClassStamp listens to a yoga class on your iPhone and produces a list of the poses it heard (a "flow"). It may miss poses or name the wrong one. Flows are for your own reference and for sharing a summary of a class. ClassStamp is not instruction, medical advice or a record to rely on for safety.

2. Recording other people

You may use ClassStamp in any class you take or teach, but you are responsible for having permission to do so.

• Some studios, teachers and venues do not allow recording. Follow their rules.
• Some places require the consent of everyone being recorded. Follow the law where you are.
• When in doubt, ask the teacher before class.

ClassStamp does not store audio or transcripts (see the privacy policy), but the listening still happens while your phone is in the room. You agree not to use ClassStamp to record anyone without the permission the place, the people or the law requires.

3. Sharing

Flows and cards you share are yours to share. Do not use them to misrepresent a teacher, a studio or a class, and respect a teacher's or studio's own sequences and brand if they ask you to.

4. Acceptable use

Don't reverse engineer the app beyond what the law allows, don't use it to break any law, and don't use it to harass or monitor anyone.

5. No warranty and limits

ClassStamp is provided "as is". To the extent the law allows, we are not liable for indirect or consequential loss, or for anything arising from recordings you make or flows you share. Nothing here limits rights you have under consumer law that cannot be limited.

6. Changes and contact

We may update these terms; the version on this page applies from its date. Questions: purafieldstudio@gmail.com.
