PaceGrid is built with privacy-by-architecture. Your data stays on your device: there is no PaceGrid account, and your workouts are never uploaded to a PaceGrid server. Data leaves your device only through the connections listed under Third-Party Services below.
Data Stored on Device Only
GPS coordinates — recorded during workouts and stored locally; your tracks leave your device only if you share or export them, or connect Strava (see below)
Health data from Apple Health — heart rate, HRV, VO2 Max, sleep and other workout metrics, read with your permission and processed locally
Heart-rate strap and smart ring data — if you pair a heart-rate strap or a supported smart ring, PaceGrid connects to it over Bluetooth and reads its data (heart rate, and from a ring also data such as blood oxygen, sleep and activity) on your device
Workout data — distance, duration, pace, elevation, kept locally
Settings and preferences — stored locally
Data We Do NOT Collect
Personal identifiers
No accounts required
No location tracking outside the workouts you record
No analytics SDKs
No advertising
No data monetisation
Third-Party Services
Strava — optional. You sign in on Strava's own page (OAuth 2.0), so your Strava password never reaches PaceGrid. Once you connect Strava, each completed GPS workout's track, title, notes and sport type upload to your Strava account automatically. You can disconnect Strava in Settings at any time.
Apple Health — optional and requires your permission. PaceGrid reads your Health data for its analytics, and saves your workouts, plus heart rate, blood oxygen and sleep from a connected smart ring, to Apple Health. Governed by Apple's privacy policy.
Apple Maps — route building. When you build a route, the points you place, and any place you search for, are sent to Apple Maps to calculate directions. Following a saved route works offline.
Cloudmesh — optional heat alerts. Only if you turn on heat alerts in Injury Guard: during outdoor workouts, an approximate location (rounded to about 10 km) is sent to Cloudmesh, Blue Flame Games' weather service, about every 15 minutes. Nothing else about you or your workout is sent, and no account or ID is attached; like any web request, it also carries your device's IP address.
OpenFreeMap — map tiles only. When a map is on screen, or you download an offline region, tiles for that area are fetched from OpenFreeMap. No personal data is sent, only tile coordinates.
Apple App Store lookup — when you open the “More from Blue Flame Games” screen and its saved list is more than a week old, PaceGrid asks Apple’s public App Store lookup for the current names and icons of our other apps; the request contains only those apps’ App Store IDs and your device’s country code.
Storage
Data is stored in an encrypted SQLite database on your device. GPS tracks are stored in binary format within sandboxed storage.
Export and Deletion
Export your data in GPX or FIT format. Delete individual activities within the app. Uninstall the app to remove all data stored on your device, except the trial start date, which is kept in the device's keychain so the free trial survives a reinstall. Copies you have uploaded to Strava or saved to Apple Health stay there until you delete them.
