Privacy Policy
Spot the Difference Studio ("we", "this site") is a free, browser-based puzzle generator. We designed it to collect as little data as possible.
What happens in your browser stays in your browser
All puzzles are generated locally on your device. The pictures you create, the PDFs you download, and the settings you choose are never uploaded to any server. This site has no user accounts, no forms that collect personal information, and no database.
Data we store on your device
If you activate a Pro license, the license key is stored in your browser's local storage so you don't have to re-enter it. It never leaves your device except when it is checked against the payment provider's license service (Gumroad) to confirm it is valid.
Payments
Pro purchases are processed by Gumroad. We never see or store your payment details. Gumroad's own privacy policy applies to the checkout process.
Advertising and analytics
This site may display advertising (such as Google AdSense) to keep the generator free. Ad providers may use cookies or similar technologies to serve ads; where required, you will be asked for consent. You can opt out of personalized advertising at Google Ads Settings. We do not run our own tracking or sell any data.
Children
The puzzles are family-friendly, but the site is operated for adults (parents, teachers, carers, publishers). We do not knowingly collect any personal information from children — or from anyone else.
