Frontier LordPrivacy policy
Frontier Lord, by CST Solution. Last updated 1 October 2026.
Frontier Lord is a game. We keep what the game needs to save your progress across phones and to deliver every purchase once. The game can show ads from Google AdMob, but only when you choose to watch one for a reward. 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) | So you can keep playing on a new phone or after a reinstall. |
| Game events, such as a building finished, a battle won or an ad watched, 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 Google Play (or Apple) and deliver it exactly once. |
Payments are handled by Google Play (or Apple). We never see your card or payment details.
Ads
The game shows only ads you choose to watch for a reward, such as finishing a short wait for free. There are no ads you have to watch. These ads come from Google AdMob, which may collect your device's advertising ID, your internet address and how you use the app, to show and measure ads. Where the law requires it (for example in the EEA, the UK and some US states), the game asks for your consent first, and you can change your choice at any time in the game's Settings (Privacy choices). You can also reset or delete your advertising ID in your phone's settings. Read how Google uses data from apps that use its services.
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.
- Ads are served by Google AdMob.
How long we keep it
Your account, email, cloud save 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 → Delete account. This deletes your account, email, sign-in keys, cloud save 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.
