What is collected. Your body data and your training data: date of birth, weight, body fat, and the injuries, conditions or substances you choose to declare. Every one of those is optional except your date of birth. Then the sets you log.
What the AI does with it. Your training details are sent to the Claude API, run by Anthropic in the USA under standard contractual clauses, which writes and adjusts your plan. Your email address is never sent. Nothing you give us is used to train AI models.
How you stop it. Withdraw this consent in Settings and no new plan is built, or delete the account and everything above goes with it. Both controls sit at the bottom of Settings, next to a one tap download of everything STARKOS holds about you.
