privacy

what we collect, what we don't.

we collect what we need to run the service: your email, your password hash (if you sign up with email), your sign-in source (google or email), your subscription status, your runs and their inputs, and the rows we've scraped from amazon on your behalf.

we don't sell your data. we don't share it with anyone who isn't directly providing the service (stripe for payments, neon for the database, vercel for hosting, resend for transactional email, amazon scout for the underlying feed).

scraped data

the time-series we accumulate is derived from publicly visible information on amazon.com (and the other five marketplaces). we don't store anything that isn't public on those pages.

cookies

one cookie holds your sign-in session — scoped to .0p.studio so the rest of the studio recognizes you. no third-party analytics cookies. no ad trackers.

retention & deletion

we keep your data while your subscription is active and for 90 days after cancellation, in case you come back. ask via the contact form to delete sooner and we'll do it within seven days.
