LairbreakerPrivacy policy
Lairbreaker, by CST Solution. Last updated 4 November 2026.
Lairbreaker is a game. We keep what the game needs to save your progress across phones, run the tournaments and deliver every purchase once. The game offers optional reward ads served by Unity LevelPlay. We do not sell your data.
What we keep
| Data | Why |
|---|---|
| A guest account: a random account ID and a secret key, made on first launch and kept on your phone | To know which progress and purchases are yours, with no sign-up. It is not linked to your name or phone number. |
| Your email address, only if you choose to add it | To save your account and sign in on another phone. We use it only to send you one-time sign-in codes, never marketing. |
| Your game progress (the cloud save), including the hero name you choose | So you can keep playing on a new phone or after a reinstall. |
| Tournament entries: hero name, class, scores | To rank players. Names and scores are shown on the in-game boards. |
| Purchase records: the store, the transaction or purchase token, the item and the date | To confirm each purchase with Google Play (or Apple), deliver it exactly once, and restore it. |
Payments are handled by Google Play (or Apple). We never see your card or payment details.
Ads
The only ads are ones you choose to watch for a reward (for example a free summon or double gold). There are no banners and no full-screen ads between runs. After you buy REMOVE ADS you get those rewards without watching. The ads are served by Unity LevelPlay (Unity Ads and ironSource Ads), which may collect your device's advertising ID, your internet address and how you use the app, to show and measure ads. In the EEA, the UK and Switzerland the game asks LevelPlay for non-personalised (contextual) ads only. The game is not directed at children. You can reset or delete your advertising ID in your phone's settings. Read Unity's privacy policy for game players.
What we don't keep
- No contacts, location, photos or microphone.
- Your internet address is used only briefly, in memory, to stop abuse (too many attempts from one address). It is not stored with your account.
Who processes it for us
- Our server is hosted in a data centre run by OVHcloud.
- Sign-in code emails are sent through Brevo.
- Purchases go through Google Play (and Apple's App Store); store connections use Unity In-App Purchasing.
- Reward ads are served by Unity LevelPlay (Unity Technologies).
How long we keep it
Your account, email, cloud save and tournament entries are kept while your account exists. Purchase records are kept, without your email, for as long as the law requires records of sales. Backups are overwritten within about a month.
Deleting your account
In the game: Settings → Account → DELETE ACCOUNT. This deletes your account, email, sign-in keys, cloud save and tournament entries at once. If you no longer have the game, see how to ask us by email.
Children
The game is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has an account, write to us and we will delete it.
Changes
If the game starts to collect anything new, this page will be updated before that version is released, and the date above will change.
