What we keep

• Your email, if you make an account.
• Your quiz answers: goal, days, gear, injuries, and the body stats you give, like age, height, and weight.
• Your workouts and cardio.
• Your chat with the coach, and short notes it keeps to remember you.
• Feedback you send, with your phone type.
• Error reports and usage totals, with nothing you typed.

Where it lives

• Signed out: on your phone.
• Signed in: in our database (Supabase), so it's there on any phone you sign in on.
• We read the chats saved there to fix mistakes and improve the coach.
• Cloudflare hosts the app and runs our server, so what you send passes through it.

The AI coach

An AI model writes the coach's replies. Your messages go to it with what it needs to answer:

• Your message and the recent chat.
• Your profile: goal, experience, days, gear, injuries, the lifts you like and avoid, and your body stats.
• Your workouts and cardio, your plans, and the workout open in Log.
• The notes the coach keeps from earlier chats.

Never your email. We send it only to write the reply.

Who gets it:

• Anthropic, which makes Claude. We send it through OpenRouter, a service that passes requests on to AI companies, or straight to Anthropic.
• Sometimes OpenAI, which makes GPT, instead. Also through OpenRouter.
• Signed in, OpenAI also turns most messages into numbers, through OpenRouter, so the coach can find your notes later.

When the app breaks

If something goes wrong on your phone or our server, we keep a short report: the error, where in the code it happened, the screen, the app version, and on a phone your browser and system, like Safari on iOS. We take out anything you might have typed, like quoted text, emails, the end of a web address, and long codes, on your phone and again on our server.

We also keep 10-minute totals of requests and coach messages: how many, how long they took, why one was turned away, and what the AI cost. They never include your messages, the coach's replies, or who sent them. Reports and totals are deleted after 30 days.

What we don't do

• No ads.
• We don't sell your data or share it for marketing.
• No tracking cookies.

Message limits

To cap messages and error reports per day, we keep a scrambled code for your phone and network. Not your address.

Your choices

• Sign out anytime. Signing out clears this phone.
• Take every set you've logged to another app or AI: You, then Export training log. We don't send it anywhere. You copy or share it yourself.
• Delete your account anytime: You, then Delete account. Your workouts, chats, what the coach remembers, quiz answers, feedback, and sign-in are erased from our database, and this phone is cleared.
