Tarna is a coaching studio. We keep the least we need to run a roster, a program, and a bill.
What we store
Account email and name. Client files your coach creates: workouts, check-ins, photos you upload, messages, wearable logs, and package payments. Billing identifiers from Stripe. Optional mail (Resend) and Strava tokens if you connect them.
Who sees it
Your coach and the staff they invite to the studio. Platform owners can see studio-level billing, not your session notes. We do not sell training data.
Your rights
Export or delete from Settings. Coaches can export a client file. Photos live in the studio database as compressed images you uploaded — delete the account and they go with it.
Questions: open Settings, or write the studio that coaches you. Terms.
