Your data, and what we do with it

• Your account — the email address you sign up with.
• Your profile — your name, and anything optional you choose to add: a self-assessed starting point, your preferred running days, and (only if you enter them) gender, date of birth, weight and an estimated max heart rate. These are used to shape and personalise your plan — never to judge you, and never as targets.
• Your running — the runs on your plan, how each one felt, and any notes or photos you add. If you connect Strava, we read your recent activities — including their route (GPS), distance, time and heart rate — so they land on your plan automatically. We only ever read from Strava; we never post to it.
• Your coaching — the messages you send the in-app AI coach, so it can answer you and remember the context of your training.
• The quiz — if you play the Rundamentals quiz, your chosen display name and scores, which appear on a shared leaderboard alongside other players’ handles and scores.

We use a small number of trusted services to run the app. They process your data on our behalf and only to provide their service — they’re not allowed to use it for their own purposes:

• Supabase — hosts our database and handles sign-in. Your data lives here.
• Strava — only if you connect it. We read your activities through Strava’s official API. You can disconnect any time in the app, and revoke access in your Strava settings.
• Anthropic (Claude) — processes your coach messages to generate the coach’s replies. It is not used to train models on your data.
• Vercel — hosts and serves the app.

• Edit or clear any profile field any time on your Profile screen.
• Disconnect Strava any time from the Connect Strava screen.
• Delete your account. On your Profile screen, “Delete my account” removes your account and every piece of data tied to it — permanently, straight away.
