Tuner help · Crow Summit Tuner privacy policy
Updated September 30, 2026. This policy covers Hilljack, developed by Vernon Hendricks under the Hendricksoft name.
Scores, copper, jugs, missions, upgrades, settings, and cached purchase status are saved on your device. Hilljack does not require a player account. Device backups may include game data.
Hilljack uses Google AdMob for ads between completed runs. Google's ad software may process IP addresses and approximate location, device identifiers, ad views and interactions, app interactions, crashes, and performance data to deliver and measure ads, prevent fraud, and maintain its services. Available privacy choices depend on your region and device settings. Where required, the game presents Google's privacy message. Available ad choices can be revisited through Settings > Ad Privacy. Remove Ads disables between-run ads. Test builds may show test ads.
Apple processes payments on iPhone and iPad. Unity In-App Purchasing checks ownership and restores purchases. Purchase services may process transaction information, device information, installation or session identifiers, and country information. Hendricksoft does not receive your payment-card details. Restore Purchases restores eligible purchases on the same store account.
If you email support, we receive the contact details and information you send and use them to respond. This website uses Google Firebase hosting, which may process technical request information to deliver and protect the website. We have not added website analytics or advertising.
Manage device privacy permissions in iOS or iPadOS Settings. Deleting the app removes its local data; it does not cancel purchases or remove store records or backups. Use Contact support for privacy questions or requests about information you provided to Hendricksoft. Service-provider information is subject to their policies and applicable retention requirements.
