Privacy Policy

Last updated: September 2026

Your images stay on your device

GridMaker is a client-side application. All image processing — uploading, gridding, and exporting — happens locally in your web browser. Your images are never uploaded to, transmitted to, or stored on any server. When you close the page, everything is gone.

Information we do not collect

We do not require accounts, we do not ask for personal information, and we do not collect the images you edit.

Local storage

We store your theme preference and Pro unlock status in your browser's local storage. See the cookie policy for details.

Cookies and analytics

We may use privacy-respecting, aggregated analytics to understand overall traffic. If advertising is displayed in the future, third-party vendors including Google may use cookies to serve ads based on prior visits. You can opt out of personalized advertising via Google Ads Settings.

Payments

If you purchase a Pro license, payment is processed by our payment provider. We receive only your email address and order status — never your card details.
