GridBlast is free to play and supported by official Google AdMob advertising. To prevent ad fraud and guarantee that only authorized advertisers can buy ad inventory in our games, Google requires developers to publish an app-ads.txt record on their official developer domain. Our verified record is publicly available at basavaraj.pages.dev/app-ads.txt.

We take player and user feedback very seriously. If you encounter any unexpected behavior, layout glitch, or have suggestions for new boosters or puzzle shapes, send an email to bm4248757@gmail.com with your device model and Android version. We typically respond within 24 to 48 hours.

Our complete Google Play and AdMob compliant disclosures are published on our Privacy Policy page. We do not collect names, credit card numbers, or personal identifying information.
