Mole Miner is a mining game you play in your browser or in our Android app. This page explains what we collect, why, and what you can do about it.
What we collect
- Your Solana wallet address. You sign in by signing a message with your wallet. We never see or store your private key or seed phrase.
- Your game progress. Your mine, upgrades, Grubs, NUGS balances, refines, claims, withdrawals and other in-game actions are saved on our server so your progress follows you between devices and so rewards can be checked for fairness.
- Basic technical data. Your IP address and device or browser details, used to keep the game running, stop cheating and abuse (for example many accounts from one network), and fix bugs.
- Bug reports you send. If you use "Report a bug", we receive your message plus your game version, screen size and recent errors.
What we don't do
- We don't sell your data.
- We don't ask for your name, email or phone number to play.
- We don't use advertising trackers. If the game shows optional rewarded ads, the ad provider may process data under its own policy.
The blockchain
Withdrawals of NUGS happen on the Solana blockchain. Transactions on a public blockchain, including your wallet address and amounts, are public and permanent. We can't change or delete them.
Who we share with
Only the services we need to run the game: our server host, our DNS and network provider, Solana RPC providers that send transactions, and Discord, where bug reports are posted to our private team channel.
How long we keep it
Game records are kept while the game runs, because they hold your balances and the history used to check rewards. Bug reports are deleted after a few weeks. Server logs are kept for a short time.
Your choices
You can stop playing at any time. To ask for a copy of your data or to have your account removed, contact us in our Discord or through the in-game bug report. Records already written to the blockchain can't be removed.
Children
Mole Miner is not meant for children under 13.
Changes
If we change this page, we'll update the date at the top and post about it in the game or on our Discord.
