Privacy Policy
Trailline tracks your days skiing and snowboarding and helps you ride with friends and family. We collect as little as we can, never sell your data, and never use it for advertising.
On this page
What stays on your phone
- Your full GPS tracks, height, weight, boot size, gear locker, setups and day history.
- Workouts you choose to save to Apple Health or Health Connect. We never read your other health data or upload health data.
What we store on our servers, and why
- Account: a random account ID created when you install the app. If you back up your account, your email or Sign in with Apple identifier.
- Profile: display name, username, birth year (to keep riders under 18 away from strangers), level and riding styles.
- Profile photo (optional): if you add one, it's stored privately and shown only to you, your friends and your family, never to strangers or people you've blocked. Remove it any time from the You tab; deleting your account deletes it too.
- Location you choose to share: when you check in to share with your crew or family, your latest position at the resort (updated about every 20 seconds, expiring after at most 12 hours). Riders you haven't connected with only see a rounded area (~100 m).
- Lift moments (optional): if lift-buddy alerts are on, which lift you're heading to, waiting for or riding, kept for 10 minutes.
- Run activity (optional): if "Help show what's open" is on, which run or lift you used and when, never your track or position. Others only see totals, with rider counts hidden below 3.
- Your content: messages, run status and condition reports, and reports about other users.
- Family (Trailline Family): family membership, and for members, today's totals (runs, lifts, vertical, top speed, last run).
- Support messages: if you use the form on our support page, your name, email, message and device details are emailed to our support inbox (through Cloudflare) and used only to answer you. Nothing from the form is stored on our servers.
- Purchases: whether you have Trailline Family, via the App Store or Google Play and our billing provider, RevenueCat.
Children
Accounts for children are created by a parent or guardian through Trailline Family. They need no email, are visible only to their family, can only message their family, and can never be found by strangers. A guardian can remove a child from the family, and deleting the child's account removes their data. If you believe a child's data was collected without consent, contact us and we'll delete it.
Who we share data with
- Supabase (database and sign-in), RevenueCat (purchases) and Cloudflare (delivering support-form messages) process data on our behalf.
- Open-Meteo receives a resort's coordinates (not yours) to look up the weather.
- Other Trailline users see only what's described above, under your sharing settings.
- We don't sell data, run ads, or use third-party analytics or tracking.
Your choices
- Sharing location, run activity and lift-buddy alerts are all off until you turn them on, and you can turn them off any time.
- Block or report any user from their profile or by holding a message. We review reports within 24 hours.
- Delete your account any time: You → Account → Delete account. This permanently deletes your server data; deleting the app removes the data on your phone.
Security and retention
Data is encrypted in transit, and access is restricted per user by database rules. Shared locations expire within 12 hours, lift moments within 10 minutes, and run activity is used for 3 hours. Messages and reports are kept until you delete your account.
