POP CLASH — Privacy Policy

Last updated: 20 August 2026

POP CLASH plays entirely offline. There is no account and no sign-in. Two features are optional and you choose whether to use them: connecting a Solana wallet, and the weekly ranking. Everything else in the game works with the network switched off, exactly as before.

What the app collects on its own

Nothing. There is no analytics, no advertising, no crash reporting and no third-party SDK that transmits data. The app requests no runtime permissions: no camera, microphone, contacts, location, storage or identifiers. Nothing is sent anywhere unless you press a button that says it will.

What the app stores on your device

One save file, held in the app's own private storage. It contains your coins, the equipment you own and have equipped, your skill levels, your quest progress, your chosen language, a count of matches played and won, and — if you have played the weekly challenge — your best time for the current week together with the recorded button presses from that run. It never leaves your device unless you submit it to the ranking. Uninstalling the app removes it.

If you connect a wallet, the app also stores your wallet's public address and the authorisation token the wallet gave it, so you do not have to approve again every time. Disconnecting removes both.

Connecting a wallet (optional)

Connecting uses the Solana Mobile Wallet Adapter, which talks to a wallet app installed on the same device. It does not use the internet. We receive nothing from it, and we never see your private key or seed phrase. The app never asks your wallet to approve a transaction, spend anything, or write to any blockchain — the only thing it ever asks for is a signature that proves you own the address, and only when you submit a ranking time.

If your wallet reports a display name for the account (for example a Seeker ID ending in .skr), the app shows that name instead of your address.

The weekly ranking (optional)

The ranking is the only part of POP CLASH that uses the internet. It is off unless you use it.

When you press SUBMIT

The app sends the following to api.oshogames.com, a server operated by OSHO GAMES:

WhatWhy
Your wallet's public addressTo identify the entry as yours. This is public information; it is not a private key.
The display name your wallet reports (e.g. osho.skr), if anyTo show a readable name on the board instead of an address.
The week number and your clear timeThe entry itself.
The button presses recorded during that runSo the server can replay the run and confirm the time is real. Without this, any time could be claimed. It is a list of which buttons were held on each frame — nothing else.
A signature made by your walletTo prove the entry came from the owner of that address.
The version number of the gameSo the server replays with the matching version of the game code.

What is sent is a record of that single challenge run. It contains no personal information, no contacts, no device identifiers and nothing about anything else you do on your phone.

When you open the ranking screen

The app requests the current board. If a wallet is connected, your public address is included in that request so the server can tell you your own position. Nothing else is sent.

What is stored, and what is public

For each week we keep one entry per wallet address: the address, the display name, the time, the recorded run, and when it was submitted. The name and the time are shown publicly on the leaderboard inside the game. The recorded run is kept so an entry can be re-checked; it is not published.

Entries are kept while the game is in service. You can ask us to delete yours at any time — email the address below from any address, telling us the wallet address to remove.

Server logs

Like any web server, ours records the IP address, time and path of requests it receives, for security and troubleshooting. These logs are rotated and discarded in the ordinary course; they are not combined with ranking entries and are not used to build a profile of anyone.

Who else receives anything

Nobody. There is no analytics provider, no advertising network and no data broker. The ranking server is run by OSHO GAMES and does not share what it holds with third parties. We would disclose information only if we were legally required to.

Children

The game is suitable for all ages and contains no advertising and no purchases. Played on its own it collects nothing, so it collects nothing from children. The ranking requires a Solana wallet, which children are unlikely to have; the only text it can display is the name supplied by a wallet, and there is no chat, messaging or other way for players to communicate.

Changes

If a future version collects anything not described here, this page will be updated before that version is released, and the change will be described here.

What changed in version 1.1

Version 1.0 had no network functionality at all. Version 1.1 adds optional wallet connection (which does not use the internet) and the optional weekly ranking (which does). The game still plays in full with the network switched off.
