HOIST — Privacy Policy
Last updated: 29 September 2026
HOIST ("the game") is made by Ogbar ("I", "me"). This policy explains what happens to your data when you play the game from Google Play.
What the game keeps
- Your progress is stored on your phone. Depth, credits, machines, research and purchases you made are saved in the game's private storage. I do not run a server and I never receive this data.
- If you are signed in to Google Play Games, the game also keeps a copy of that save in your Play Games account (Google Play Games Saved Games), so a new phone or a reinstall can bring it back. The copy belongs to your Google account; I cannot see it. You can delete it from the Play Games app or by removing HOIST from your Play Games profile.
- If you have Android backup turned on, Android may include the game's save in your personal Google backup. That backup belongs to your Google account; I cannot see it.
- The game has no accounts of its own and no chat, and does not ask for your name, e-mail or contacts. Signing in to Google Play Games is optional and handled by Google.
Ads (Google AdMob)
The game can show rewarded ads, only when you choose to watch one. The ads come from Google AdMob. To show and measure ads, Google may collect:
- your device's advertising ID,
- your approximate location, derived from your IP address,
- information about how you use the app and see ads,
- diagnostic information such as crash logs.
In the European Economic Area, the United Kingdom and Switzerland the game asks for your consent before it requests any ad, and you can change your choice at any time in Settings → Privacy options. If you do not consent, you still get ads (non-personalised) and the same rewards.
How Google uses this data: policies.google.com/technologies/partner-sites. You can reset or delete your advertising ID in your phone's Settings → Google → Ads.
Purchases (Google Play)
In-app purchases are handled entirely by Google Play. I never see your payment details. The game receives only a confirmation (a purchase token) from Google Play, which it uses on your phone to give you the item.
Children
The game is not directed at children under 13, and I do not knowingly collect data from them.
Deleting your data
- Your game data: Settings → Reset in the game, or uninstall the game.
- Advertising data: through your Google account and device ad settings (see above).
Changes
If this policy changes, the new version will be published at this address with a new date.
