Who we are

Tunnel Coaching is a booking tool for indoor-skydiving coaches. It runs at tunnelcoaching.app and in the Tunnel Coaching iOS app, which shows the same service.

What we collect

If you request a session we store the name, email address, optional phone number, country and any notes you type into the booking form, together with the slots you selected. Your coach needs these to confirm the booking and contact you.

If you are a coach we store your email address, name, booking-page details, availability, confirmed sessions, student records and your settings. Passwords are stored only as a salted scrypt hash. Optional integration tokens (Notion) are encrypted at rest.

Everyone generates basic usage data: which pages were viewed and when. It is used to show coaches how their booking page is performing.

The iOS app

The app shows the same website inside a native shell. It additionally stores, on your device only: booking requests you made in the app, so it can remind you the day before you fly.

Face ID sign-in. If a coach turns it on, their email address and password are saved in the iOS Keychain on that device and unlocked with Face ID to fill the sign-in form. The Keychain entry never leaves the phone, is not included in iCloud or device backups, and we never receive it. Face ID itself is handled entirely by iOS — the app is only told whether the check passed. Turning the setting off erases the saved details, as does deleting the app.

If you allow notifications as a coach, a push token is sent to us and linked to your account so we can tell you about new booking requests. Push delivery goes through Expo's push service and Apple's APNs. Turning notifications off in iOS Settings, or signing out, stops this.

If you allow calendar access, sessions are written to a calendar on your device. We never read your existing calendar entries.

What we never do

We do not sell personal data, we do not run advertising, and we do not share your details with third parties beyond the service providers needed to run the product (hosting, database, email delivery, push delivery).

Keeping and deleting data

Coaches can ask for their account to be deleted at any time — in the app under Settings → Delete my account, or on the web at /account/delete. The request takes effect straight away: the account is suspended, you are signed out and your booking page stops accepting requests. The operator then permanently erases the account, availability, sessions, students, settings and analytics — normally within a few days. A coach's records are linked to student histories and to bookings clients already hold, which is why the final erase is done by a person rather than by a single tap.

If you requested a session as a client and want your details removed, email us and we will delete them.
