You can permanently delete your account and the training data owned by it.
Sign in, then confirm deletion. This cannot be undone.
Account deletion cancels an active TrainCraft web subscription (Paddle) immediately, without a refund, and disconnects Strava and Garmin. It cannot cancel App Store or Google Play subscriptions; cancel those in the store before deleting your account.
Payment processors (Paddle, the App Store and Google Play) keep their own records of your payments. TrainCraft keeps transaction amounts and dates without your identity where needed for accounting and refunds, and a non-reversible hash that prevents a deleted account from being restored.
