On your device
What stays on your iPhone
Your full run data lives on your iPhone and syncs to your other Apple devices through iCloud. This includes GPS routes, heart rate, pace splits, shoe mileage, personal records, and training plans. We never see this data. Apple handles the sync, and only your Apple ID can access it.
On our servers
What we hold
The social side of Cursa runs on our servers (Supabase, hosted on AWS). This is limited to:
- Your profile: display name and share code
- Your social graph: who you follow, clubs you belong to
- Your interactions: kudos, comments, RSVPs
- Run summaries: distance, pace, and time for runs you choose to share
Your full GPS route is never uploaded unless you explicitly choose to share it. Run summaries contain only the numbers, not where you went.
Your controls
You decide who sees what
Every piece of shared data has its own visibility setting:
- Profile visibility: Public, Followers only, or Private
- Route visibility: Public, Followers only, or Hidden
- Stats visibility: Public, Followers only, or Mutual follows only
- Ghost mode: Run without appearing in anyone's feed at all
Routes are trimmed by default. The first and last 400 meters of every GPS route are hidden so nobody can pinpoint where you live. You can adjust this from 0 to 1 km, or hide routes entirely.
What we won't do
Lines we don't cross
- We do not sell your data. Not to advertisers, not to data brokers, not to anyone.
- We do not track you outside the app.
- We do not use your run data to train machine learning models.
- We do not share your information with third parties unless you connect a specific integration (like Garmin) and authorize it yourself.
Leaving
Take your data and go
Cursa includes a full data export. Go to Me → Privacy → Download my data, and you will get a JSON file containing everything we have.
To delete your account: open the Me tab, scroll to the bottom of the settings section, and tap Delete Account below the Sign Out button. This permanently removes your profile, social connections, and any shared run data from our servers. Your on-device data — GPS routes, Apple Health runs, training plans — is stored by iOS and is not affected; remove the app if you want to clear that too.
Cursa ships a privacy manifest (PrivacyInfo.xcprivacy) as required by Apple. The App Store privacy nutrition label for Cursa reflects the actual data practices described on this page.
