Calculator inputs stay in your browser unless you save a portfolio as a Pro user. If you create an account we store: your email address, sign-in timestamps, subscription status, and any portfolios you save. Written diagnoses are generated from the data you submit and are not used to train models.
No player-level personal data should be entered into the service; inputs are aggregated cohort metrics. We do not use advertising trackers.
Cloudflare (hosting, database, bot protection; EU region for data at rest), Resend (transactional email for sign-in links), our merchant of record (payment processing; they handle card data, we never see it), and a crypto payment processor for annual crypto plans. Each processes data only to provide their function.
We process account data to perform the contract with you (Art. 6(1)(b) GDPR). Accounts inactive for 24 months are deleted. You can request access, correction, export or deletion of your data at any time.
One session cookie for login. No third-party advertising cookies.
