privacy policy
last updated: June 26, 2026
spin sensei ("we", "us") is a DJ-practice app published by JCLVSH LLC. this policy explains what we collect, why, and the control you have over it. we keep it short because we collect little.
what we collect
- account identifier. on first launch the app creates an anonymous account so your progress can sync — no signup, no name, no email required. if you choose Sign in with Apple to back up your progress, we receive your Apple user identifier and, only if you allow it, your name.
- practice data. the drills you complete, your scores, XP, streaks, and levels. this is what powers your progress, syncing across devices, and the leaderboard.
- display name.optional. if you set one for the leaderboard, it is shown publicly there. we don't set it from your real name.
- push token. if you enable reminders/notifications, a device push token so we can send streak reminders. you can turn this off in iOS Settings at any time.
- waitlist email. if you join the waitlist on this site, your email — used only to tell you when the app launches.
what we do not do
- we do not sell your data.
- we do not track you across other apps or websites, and there is no third-party advertising.
- we don't collect your location, contacts, photos, or microphone.
where it lives
your data is stored on our backend provider, Supabase. subscriptions, if you purchase one, are processed by Apple and managed through RevenueCat — we never see your payment details.
your choices
- delete everything.the app has an in-app "delete account" option (Settings) that permanently erases your account and all associated data from our servers.
- notifications. turn reminders off in the app or in iOS Settings.
- waitlist. reply to any waitlist email to be removed.
children
spin sensei is not directed to children under 13, and we don't knowingly collect their data.
changes
if this policy changes materially, we'll update the date above and, where appropriate, notify you in the app.
