Privacy policy
Ironspire Legion, by CST Solution. Last updated 13 October 2026.
Ironspire Legion is a game. We keep what the game needs to save your progress across phones, to run the online Arena, to check idle progress, and to deliver every purchase once. 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 device | 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 device. We use it only to send you one-time sign-in codes, never marketing. |
| Your game progress (the cloud save) | So you can keep playing on a new device or after a reinstall. |
| Your Arena defence team (heroes, levels, gear stats), the player name you choose, your Arena rating and fights | To match you with other players. Other players see your defence team, your player name and your rating, and can watch fights against it. |
| Idle results: the time you were away and the battles your team fought | To check idle progress against the server's clock and battle engine. |
| Game events, such as a floor cleared or a battle won, with the time | To fix bugs and balance the game. They are tied to your account ID, not to your name. |
| Purchase records: the store, the purchase token or transaction ID, the item and the date | To confirm each purchase with Apple or Google Play and deliver it exactly once. |
Payments are handled by Apple or Google Play. We never see your card or payment details.
Ads
The game does not show ads at present. If ads are added, this page will be updated before that version is released.
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 Apple's App Store and Google Play; store connections use Unity In-App Purchasing.
How long we keep it
Your account, email, cloud save, Arena data and game events 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, Arena team, rating and fights, and game events 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.
