What the app reads
With your permission, the app reads running workouts, heart rate and walking and running distance from Apple Health, to tell which planned workouts you have done. It never writes to Health.
What is stored
For each run you link to your plan, mark as extra or ignore, the app stores a summary: start time, distance, duration, average pace, average heart rate and the workout's Health identifier. It also stores your plan, workouts, pace zones and a log of changes, plus your account email and your phone's notification token, used only to tell the app your plan changed. Everything sits in your own rows in a Supabase database in Sydney, Australia, and row level security keeps each account to its own data.
If you connect intervals.icu, the app sends your planned runs for the next 7 days (date, title, coach notes, steps and targets) from your iPhone to your own intervals.icu account, using an API key you paste in. It also reads your intervals.icu athlete name, LTHR (lactate threshold heart rate) and Run threshold pace, to show the connection, set heart rate targets and set a planned load on the runs it sends. To link a finished run to its planned workout, it reads your intervals.icu activities from the last 3 days (each one's id, type and start time); linking renames the activity to the planned workout's name. The key stays in your iPhone's keychain and never reaches our servers. Disconnecting deletes the key and, while intervals.icu still accepts it, removes the upcoming runs the app added there.
AI assistants
An AI assistant, such as Claude or ChatGPT, can read and change your plan only through a connector you add and authorise yourself. What the assistant does with that data is covered by your agreement with the company that provides it, such as Anthropic for Claude or OpenAI for ChatGPT.
What is not done
No advertising, no analytics, no tracking, and no sale of data. The only services that handle it are Supabase (database and sign-in, Sydney), Vercel (this website), Resend (sign-in emails, which see your email address) and, if you connect it, intervals.icu (the planned runs and links described above). Health data is never used for advertising.
Deleting your data
