Privacy Policy · TrekGPS

Provider and scope

TrekGPS (行者精准定位) is a KingShark brand app provided by Gongyi Jinsha Technology Co., Ltd. Updated and effective November 10, 2026. This policy explains data handling, permission requests, recipients and data controls for the iOS app. Contact: support@kingshartktech.cn.

Local data and retention

Tracks, places, motion classifications, photo copies, notes, privacy zones and weather caches remain on your device until deletion, cleanup or uninstall. Some temporary files are managed through cache cleanup. Region names and temporary map targets are retained briefly in memory. This version has no TrekGPS account, cloud sync, ads or third-party analytics SDKs and does not upload tracks or photos to our servers. System backups and exported files are managed by the relevant system or recipient.

Location and precise location

Requested when you use instruments, fetch a place’s location, query weather or start recording. Used for location, direction, altitude, region names, place guidance, weather and tracks. Background location supports recording while locked. Denial prevents live location and normal track recording; disabling precise location reduces accuracy. Existing data remains available. Revoke access in system settings or pause/end recording.

Camera and photo selection

Camera access is requested when you take activity or place photos. Denial disables in-app capture; you may still use the system photo picker. The picker provides only selected images without requesting full-library access. The app creates local copies with EXIF location and other metadata removed and does not alter or delete originals. Visual content and text may still reveal places.

Motion, pressure and instrument sensors

Motion and fitness permission is requested for automatic travel classification or pressure readings. Denial may disable these features; manual mode and GPS recording remain available. While visible in the foreground, the instrument uses device motion for movement wake and, while awake, leveling assistance. Leaving the instrument or backgrounding stops its collection without stopping an active recording. Motion information is not uploaded.

Network services and data sent to Apple

Weather requests send coordinates rounded to three decimal places to Apple Weather, following cache rules when the environment panel is opened: at least four hours apart and at most five attempts per rolling 24 hours. Reverse geocoding sends coordinates to Apple for region names. Opening maps or search sends map regions, search terms and nearby-search location to Apple Maps. These requests do not send entire tracks or photos. Apple handles its services under its privacy policy. The app does not request contacts or microphone access.

Purchases and transaction verification

Apple processes payments. The app reads product information, verified transactions, subscription validity and renewal status to provide Pro access, restore purchases and handle refunds or revocations. We do not receive payment-card information. Apple determines trial eligibility; see the Terms of Use and purchase confirmation.

Sharing, deletion and withdrawal

Only your explicit sharing sends selected media, GPX or diagnostics to a chosen app. GPX contains precise location and does not apply media cropping. Diagnostic text excludes track coordinates and photos. Photos, text and route shapes may identify places; review before sharing. Delete activities, places, photo copies and notes in the app, clear export caches in settings and retry incomplete cleanup in Help. Local deletion does not remove photo-library originals, backups or recipient copies. There is no account to close. Revoke permissions in system settings to stop related future access.

Security, minors and policy updates

System permissions, the app sandbox and Apple transaction verification restrict access, but cannot prevent all loss caused by device failure or user error. Back up important data. The app is not directed at children; minors should use it with guardian guidance and obtain required purchase permission. Contact the email above about access, correction, deletion or minors’ information without sending full private tracks. Material data-handling changes will be communicated in-app or through release notes, with renewed consent where applicable.
