Gridlock: Block Puzzle
Last updated 5 September 2026
The short version. Gridlock has no accounts and no sign-in. Your scores and your game in progress are stored on your device and never sent anywhere. The app is free and supported by advertising, and the advertising provider collects some data in order to serve ads.
This policy covers the Gridlock iOS app and this website, both published by Grounded Tech Co.
The following stays on your iPhone and is not transmitted anywhere:
Deleting the app removes all of it.
Gridlock shows ads through Google AdMob. To serve them, Google may collect and process:
Google handles this data under its own policy, at policies.google.com/privacy. How Google uses data from apps that use its services is described at policies.google.com/technologies/partner-sites.
Grounded Tech Co does not collect this data itself, does not have access to it in an identifiable form, and does not sell it.
App Tracking Transparency. On first launch, iOS asks whether Gridlock may track your activity across other companies' apps and websites. Decline and the IDFA is not used; you will see less relevant ads. The game itself is unaffected either way. Change it any time in Settings → Privacy & Security → Tracking.
Consent in the EEA, UK and Switzerland. In these regions Gridlock presents a consent form from Google's User Messaging Platform before requesting any ads. You can decline personalised advertising there, and the choice is remembered.
System-wide. iOS offers Settings → Privacy & Security → Apple Advertising to control personalised advertising across all apps.
Leaderboards are optional and provided by Apple's Game Center. If you sign in, your Game Center alias and score are visible to other players on the leaderboard. Gridlock submits only a numeric score. Apple's handling is covered by the Apple Privacy Policy. Declining Game Center hides the leaderboard and changes nothing else.
Gridlock includes no separate analytics service. There is no crash reporting, behavioural analytics, or attribution SDK beyond what Google AdMob performs to serve and measure advertising.
Gridlock is rated 4+ but is intended for a general audience and is not directed at children under 13. It is not distributed in the App Store Kids Category. The app does not knowingly collect personal information from children. If you believe a child has provided personal information through the app, write to the address below and it will be removed.
Grounded Tech Co operates no servers and stores none of your data, so there is nothing for us to retain or delete. Data processed by Google for advertising is retained under Google's own policies and may be processed outside your country.
Depending on where you live you may have rights to access, correct, or delete personal data held about you, and to object to certain processing. Since we hold no personal data about you, requests about advertising data are directed to Google. You can review and control what Google associates with you at myadcenter.google.com.
A revised policy will be posted here with a new date at the top. Material changes to how data is collected will also be noted in the app's release notes.
