Common questions
My progress disappeared.
Progress is saved on your device, not in an account, so it does not follow you to a new phone and it is removed if you delete the game. If progress vanished on the same device without reinstalling, please email us with the device and OS version — that would be a bug and we want it.
I am colour blind and cannot tell the compounds apart.
Turn on Show compound symbols in Settings. Every compound then carries a distinct shape as well as a colour, which is the reliable way to read the harder labs. The setting is saved.
Can I turn the ads off?
Rewarded ads are always optional — you choose whether to watch one, and there is an in-game currency alternative. Where a Remove Ads purchase is offered, buying it removes banner and interstitial ads permanently on that device.
How do I change my ad privacy choice?
Open Settings → Ad privacy choices in the game. This appears where privacy regulations require it, and it reopens the same consent form you saw the first time.
How do I delete my data?
Delete the app. Everything our games store is on your device, so removing the app removes all of it. We hold no account and no server-side copy — there is nothing for us to delete on our side. See the Privacy Policy for exactly what is stored.
A level seems impossible.
It is not — every board is generated so that a complete solution is guaranteed to exist before it ever reaches you. If you are stuck, Undo is unlimited, and a hint will show a move that keeps the cure reachable. If you believe you have found a genuinely unsolvable board, please tell us which game, difficulty and level number.
