SlopCheck only ever reads what YouTube already publishes about a channel publicly: its handle/URL and its public upload feed (titles, descriptions, thumbnails, publish times of the most recent 15 videos). We do not ask for your Google account, YouTube Studio login, or any credential -- there is nothing to authenticate, because nothing we read is private.
We do not store the channel you check, the videos we fetch, or the report we generate. Everything is re-derived fresh from YouTube's public feed on every request. If you leave an optional email address for the free check, it is forwarded once to our own alert channel and not stored in a database. Payment is processed by Stripe for the $19 report -- we do not see or store your card details; see Stripe's privacy policy.
Questions: use the contact details you provided at checkout.
