Account: your email and a salted password hash (PBKDF2). Usage: the stimuli you submit, the simulations generated from them, and your credit ledger. Cookies: a session cookie when signed in, and an anonymous cookie that tracks whether your free simulation was used. No third-party analytics or ad trackers.
Card numbers (Stripe handles payment entirely), your name, your phone, your contacts, or anything we don't need to run the service.
To run simulations, maintain your balance, fulfill purchases (Stripe sends us a confirmation event with your account reference), and debug the service. Stimuli may be processed by our model provider to generate output. We don't sell or share your data with advertisers.
If you copy a share link or card, that simulation becomes viewable by anyone with the link. Don't put secrets in a stimulus you plan to share.
Email desk@xemulator.example from your account address and we delete the account, its simulations, and its ledger within 30 days (records required for payment compliance are retained as law requires).
