Terms of Use
Branchline — Train Tracks
Last updated: 28 August 2026
What this is
Branchline is a logic puzzle game. These terms cover your use of it. By installing and using the app, you accept them.
What you can do
Use Branchline on any device you own, for as long as you like, for free. Play, share your results, and enjoy it.
What you cannot do
- Decompile, reverse engineer, or extract the puzzle files for redistribution
- Republish the app or its puzzles as your own
- Use the Branchline name, icon, or artwork for anything other than talking about the app
The puzzles are generated by us and are ours. The rules of Train Tracks are not — nobody owns them, and you are welcome to write your own game.
Advertising
Branchline is free and has no paid version. It shows one optional advertisement: a reward video you can choose to watch to reveal a square of the puzzle you are solving. Nothing is shown unless you ask for it.
Those videos come from Google AdMob, which collects data to serve them. What it collects, and how to control it, is set out in the Privacy Policy.
We do not control which advertisements you are shown and we do not endorse them. If an advertisement is broken, misleading, or inappropriate, tell us at the address below and we will report it, but the advertiser and Google are responsible for its content.
No warranty
Branchline is provided as it is. We do not promise it is free of bugs, that it will always work on your device, or that a future version will keep any particular feature. Your progress is stored only on your device: if you lose the device, uninstall the app, or clear its data, that progress is gone and we cannot recover it, because we never had a copy.
Limitation of liability
To the extent the law allows, we are not liable for any loss arising from using the app — including lost progress or lost time.
Changes
These terms may change when the app changes. The date at the top will change with them, and the current version always lives at this address.
