Browsing the free site requires no account and collects no personal data beyond standard server logs. If you create an account, sign-in and profile data (email, name if you provide one) are handled by Clerk, our authentication provider. Payments are processed by Stripe; we never see or store card numbers.
Our own database stores, for members: your Clerk user id, the cards you save to your collection (with any group names you type), and daily counters for rate-limited actions. That's the full list — no browsing history, no analytics profiles, no ad tracking.
Deleting your account (from the account menu) removes your identity at Clerk; email chushi.li1@gmail.com to have your collection rows and usage counters removed too, or with any other privacy question.
