No. There are no Chronotrace accounts. Your progress is saved on your device, and on iPhone and iPad it also syncs through Game Center if you are signed in.

Open the Shop and tap Restore purchases, signed in with the same Apple ID or Google account you bought with. If it still doesn’t appear, email us with the date of purchase.

Purchases are handled by Apple and Google. Request a refund at reportaproblem.apple.com (iPhone/iPad) or from your Google Play account (Android).

Levels 1 to 5 never show ads. After that, buy Remove Ads in the shop to turn off ads between levels and the banner. Watching an optional ad for a free Chrono Charge stays available if you want it.

No. Every one of the 50 rooms can be cleared without any power-ups. They make some rooms easier, and runs that use them are marked “Assisted”.

If something stops one of your Echoes from repeating what you did (a box in its way, or you standing where it needs to be), time snaps back to the start of your current recording. A Chrono Charge cancels a Paradox instead: the Echo that went out of sync dissolves.

Every room has a solution with the tools shown. Try recording an Echo that waits longer on a plate, freezing objects at a different moment, or rewinding and trying again. The Time Shard in each room is optional.

On iPhone and iPad, if you are signed in to Game Center, your progress (stars, best times and Chrono Charges) syncs automatically and comes back when you reinstall or switch devices. Otherwise progress is stored only on your device and is lost if you delete the app. Purchases can always be restored with Restore purchases.
