Radius — privacy policy

Radius collects no data. Nothing about you or your location is stored off your device or shared with anyone, ever. Tips are handled entirely by Apple; we never learn who you are.

This policy covers the Radius app for iPhone and iPad. Below is exactly what that means, and the few places where something does leave your phone because you asked it to.

Your location

Radius reads your phone's position to compare it with the zones you set. Each position is used for that comparison, shown on screen while the app is open, and then discarded. Radius keeps no history, no trail, no log of when you entered or left a zone, and no record of any kind of where the phone has been.

What stays on your device

• Your zones (name, center, distance, warning ring, keep-out or keep-in) and your settings. They are protected at rest and excluded from iCloud backup.
• Street packs you import, kept in the app's private storage and never backed up.

Deleting the app deletes all of it. Settings › Privacy › Wipe all zones deletes your zones immediately.

Network

Radius has no networking code of its own. Three things can leave your phone, and only when you start them:

• Address lookup. When you type an address for a zone, the text you typed is sent once to your phone's built-in geocoder (Apple's) to turn it into coordinates. Your position is never part of that request. Enter coordinates instead and nothing is sent.
• Street packs. You download them yourself, in your web browser, from our packs page. The site is hosted on GitHub, which — like any web host — sees an ordinary download request (your IP address and which region file you chose). It never learns where you are inside that region, and we do not receive GitHub's logs.
• Tips. If you choose to leave a tip, Apple processes the purchase under Apple's terms. Radius learns only that a tip went through on this device — never your name, Apple ID or payment details — and no location is part of it. The tip screen is the only part of Radius that talks to a server, and it does nothing until you open it.

Notifications and speech

Warnings, alarms and spoken alerts are created on the phone. Alerts contain only the zone name you chose and a distance — never an address or a time. Speech is generated by the phone's own voice.

No accounts, analytics or ads

Radius has no account, no sign-in, no analytics, no crash reporting, no advertising and no third-party code of any kind.

What we can't control

This policy covers what Radius does. Your phone's operating system, Apple and your mobile carrier have their own location and data practices, which Radius cannot change. Check Location Services if you want to limit those too.

Children

Radius is not directed at children. It collects no data from anyone.

Changes and contact

If this policy changes, the new version will be posted here with a new effective date. Questions: ljna2714@proton.me.
