Privacy policy

This policy explains what GYST ("the app") collects, why, and how you can control it. GYST is built to collect as little as it needs to plan your trips.

What we collect

Account. You sign in with Sign in with Apple, or use the app as a guest without creating an account. A signed-in account is linked to the identifier Apple provides; we don't receive your Apple ID password.

Trip and vehicle data. Trips you plan or save, your vehicle details, and app preferences are stored in our hosted backend so they sync across sessions and, if you signed in, across devices.

Location. GYST uses your location — including in the background during an active trip — to plan routes, find nearby chargers, and track trip progress on your Lock Screen, Dynamic Island, and CarPlay.

Camera and photo library. Used only if you attach a photo to a hidden-gem or charger report you choose to submit.

Microphone and speech recognition. Used only when you search for a destination by voice, to convert your speech into a search query.

Motion. Used to improve trip accuracy and detect driving conditions.

Calendars and Reminders. Used only if you choose to plan charging around your schedule or create charging-stop reminders.

Face ID. Used on-device to secure your sign-in. GYST never receives your Face ID data — iOS handles this locally.

Crash and diagnostic reports. If the app crashes or misbehaves, a report (device model, OS version, what the app was doing) is sent to our crash-reporting service so we can fix it.

Subscription information. If you subscribe, purchase processing is handled by our subscription provider and Apple; we receive your subscription status, not your payment details.

Who processes it

We use a small number of service providers to run GYST, each processing only the data needed for their function:

  • Supabase — hosts our backend database and authentication (account, trip, and vehicle data).
  • Sentry — receives crash and diagnostic reports.
  • RevenueCat — processes and manages subscriptions.
  • Apple — provides Sign in with Apple, App Store subscription billing, and on-device Face ID.

We don't sell your data, and we don't share it with anyone beyond these processors and as required by law.

Retention

We keep your account and trip data for as long as your account is active. Crash reports are retained by our crash-reporting provider on their standard retention schedule. If you delete your account, your data is deleted as described below.

Children

GYST is not directed at children under 13, and we don't knowingly collect data from anyone under 13.

Your rights and choices

From Settings in the app, you can export a copy of your data or delete your account and its associated data at any time — no email required. You can also revoke camera, photo, microphone, location, motion, calendar, or reminders access at any time in iOS Settings → GYST.

Changes

If this policy changes, we'll update this page and the date above.
