Trapline privacy policy
Last updated 15 September 2026
Trapline is built to know as little about you as possible. There is no sign-up, no advertising and no tracking. Signing in to Game Center is optional and happens through Apple.
What stays on your device
Your progress (bolts, cores, research, settings and the course you are building) is saved on your phone. Deleting the app deletes it.
What our server keeps
When the game is online it talks to our server at trapline.theronix.app. The server keeps:
- a random player id and a generated handle such as @swift-otter-4217, never your name, email or phone number;
- if your phone is signed in to Game Center: your Game Center player id for this game and your Game Center nickname. Apple checks it is really you; we use it to show your nickname instead of the handle and to find your player again on another device or after a reinstall;
- the courses you publish (their layout, name from a fixed list, music and laugh);
- which courses you have run and cleared, your best flip count, the courses you like and report;
- your score on the daily course.
Other players see your Game Center nickname (or, without Game Center, your handle) next to your courses and your daily scores, and on the weekly builders board with the number of players who ran your courses. That is all they see. If you would rather be shown by your handle, email us and we will switch it.
Like any website, the server sees your IP address when your phone connects. It is used only to stop abuse (limits on how fast one address can publish or create players) and is not stored with your player data.
What we never collect
No name, email, contacts, location, photos, advertising identifier or device fingerprint. We do not sell or share data, and there are no third-party analytics or ad services in the app.
Purchases
In-app purchases are handled by Apple. We never see your payment details.
Children
Trapline is rated 9+. Because it collects no personal information, it asks for none from anyone.
Deleting your data
In the game, open Settings and tap Delete my online data. That deletes your player id, handle, Game Center id and nickname, and everything linked to them from our server at once: your published courses, runs, likes, reports and daily scores. The game then stays offline until you choose to go online again. You can also email info@monah.me with your handle and we will delete it for you.
