Privacy policy

LoEUC is an electric unicycle telemetry application.

Data processed by the app#

• Bluetooth device identifiers and electric unicycle telemetry.
• Ride history and dashboard settings.
• Location data, used to record a ride route when you grant location permission.

Storage and transmission#

All of it is stored locally on your device. LoEUC does not transmit wheel telemetry, ride history or GPS routes to the developer, and sends none of it anywhere on its own.

There is one exception, and it happens only when you press "Share", "Copy link" or "QR" on a dashboard preset. At that moment the dashboard layout alone is sent to loeuc.ru and kept there: which tiles you have, their sizes and colours, the pinned band setup, plus the preset name and wheel label you typed. No telemetry, no rides, no routes and no device identifier.

What is worth knowing about those links:

• a link is not password protected — anyone holding it can read the preset;
• a record is deleted automatically once its link has gone a year without being opened;
• with no network the app hands you the long self-contained link instead, which carries the whole preset and puts nothing on the server at all. Sharing by file or through the clipboard works the same way.

For a published preset the app may silently create a guest account so this and later presets have an owner. The server keeps its identifier, public name and a recovery-key hash, not the key itself; the device token remains only in the app's protected storage. The key is shown once: if you lose it, the guest account cannot be recovered until it is upgraded on the website. You can revoke the local session in settings; this removes the device's access but does not delete already published presets.

Telegram photos are retained for at most 90 days, solely for private administrator feedback ingestion. This has nothing to do with preset sharing: sharing never uploads wheel telemetry, ride history or location.

Apple may process TestFlight diagnostics, crash reports and feedback according to Apple's own privacy terms when you install a beta through TestFlight.

Permissions#

Bluetooth access is used to discover and communicate with electric unicycles. Location access is used only to record ride routes. Both permissions can be revoked in your phone settings.

Data deletion#

Ride records can be deleted inside the application. Removing LoEUC from the device removes its locally stored application data.

Changes#

This policy will be updated if LoEUC begins using additional data or network services.

Contact#

The public contact email published with the LoEUC TestFlight or App Store listing can be used for privacy questions.
