Who is responsible
Grindly is published by SKA Digital LLC, operating as SKA Digital Studio. Contact us at contact@skadigitalstudio.com.
Data stored on your iPhone
- Workout history, earned minutes, preferences, alarms and Screen Time choices.
- Nutrition profile, meal journal, water tracking and body-journal photos.
- Camera frames used for rep counting, alarm missions and meal recognition are processed on-device. Grindly does not upload or retain those images on its servers.
Friend Challenges
An anonymous guest account is created without an email or password. Your user ID, display name, username and Challenge stats such as XP, streaks, reps and wins are sent to Supabase so invites and leaderboards work. Profile photos remain on your device.
Nutrition searches
When the local food database cannot answer a search, a food name or barcode may be sent to Open Food Facts and, when configured, USDA FoodData Central. Meal photos are not sent to those services.
Apple system services
App blocking uses Apple Family Controls and Screen Time APIs. Grindly does not receive the identity of the apps you select. Alarm delivery depends on iOS, device permissions and compatible system services.
Sharing and tracking
We do not sell personal data, show third-party advertising or use data to track you across apps and websites. Data is shared only with the providers named above to operate the requested feature.
Retention and deletion
Local data remains until you delete it or uninstall Grindly. Challenge data remains while the guest account is active. In Grindly, open Settings > Account > Delete account to permanently remove the guest account, Challenge data and local app data.
Your choices and contact
You can change camera and notification permissions in iOS Settings and Screen Time authorization in the app. For access, correction, deletion or privacy questions, contact contact@skadigitalstudio.com. Grindly is not intended for children under 13.
