Signed in, these return your own data as JSON straight in the browser. That is the portable export, no request needed: /athlete, /plan/current, /history, /session/week, /week/changelog and /auth/devices.

Your meal picks, diet preference and allergen filters live only in this browser and were never sent to the server. Clearing your browser data removes them.

Deleting removes, in one go:

• your account and email address;
• your whole training history: every logged set, note, flag and heart-rate summary, and the plan built from it;
• your athlete profile: bodyweight, sex, height, age and goal;
• every paired watch. They stop syncing immediately and cannot be re-linked;
• this sign-in session and any sign-in code already on its way to your inbox;
• your place on the early-access list. Your address comes off it entirely, so coming back later means asking for access again and waiting for a place.

There is no undo and no backup to restore from. If you are let back in later and sign up with the same address, you start from week zero. Export anything you want to keep first.
