Common questions

The game crashed or something looks broken

Sorry about that. Email us with your device model and operating-system version (for example, “Pixel 8, Android 15”) and a quick note on what happened — which city you were playing helps too. Details like these let us reproduce the problem and fix it fast.

I got a new phone — how do I move my progress?

PieceSwap has no accounts and no sign-in. Your progress is stored on your device, which keeps things private and lets you play without ever handing over an email address — but it also means progress does not transfer between devices, and uninstalling the game removes it. If something went wrong on the same device, get in touch and we will help.

Does the game use my own photos?

No. Every image in PieceSwap ships inside the app, and AI tools may be used in creating some of them. The game never asks for photo-library permission and cannot read your camera roll, your camera, or your files.

The game asked for permission to track me

On Apple devices you may see an App Tracking Transparency prompt. We use it only for advertising and measurement. You are free to decline, and the game keeps working exactly the same, with every city and puzzle available. You can change your choice any time in your device’s privacy settings.

Is the game free? Are there in-app purchases?

The game is free to download and play, and it shows advertising. It also offers optional in-app purchases — but you can play and finish it without spending anything.

I bought something and it did not arrive

Email us with the date of the purchase and the item you expected, and we will look into it. Because payments are handled by the Apple App Store or Google Play, your app-store receipt is the useful thing to have to hand — and for refunds or billing disputes, your app-store account is the place to start, since that is where the payment was taken.

I have a question about my data or privacy

We are built around collecting as little as possible — no accounts, no email collection, no access to your photos. The full details are in our Privacy Policy, and you can always email us with a specific request.

I have feedback, or a city you should add

We would genuinely like to hear it. Send it over — requests from players shape which destinations and features we build next.
