What we collect
DataStructure360 has no accounts and no sign-up. The values you type into the visualizers are processed in your browser and are not sent to our servers. Our hosting provider, Vercel, may keep standard server logs such as IP address, browser type and requested page for security and operations.
Local storage
We use your browser's local storage to save your theme preference (dark or light mode) and whether you have completed the tutorial. No personal information is stored.
Advertising
This site uses Google AdSense to show ads. Google and its partners use cookies and similar technologies to serve and measure ads, which can include ads based on your previous visits to this or other sites. You can manage personalized advertising in Google Ad Settings and learn more at How Google uses information from sites that use its services. Where required, such as in the European Economic Area and the United Kingdom, ads are shown according to the consent choice you make in the consent message.
Fonts
Pages load fonts from Google Fonts, which means your browser contacts Google servers to download them.
