Information we collect

We do not require accounts and do not collect personal information directly. Our hosting provider may collect standard, aggregated technical logs (such as request counts) to operate the service.

Advertising and cookies

This site is supported by advertising served by Google AdSense. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising at Google Ads Settings. See how Google uses data from sites that use its services for details. We do not set our own tracking cookies.

Third-party resources

Tool pages load open-source JavaScript libraries (PapaParse, JSZip) from a public CDN. These requests are standard static-file fetches and do not include your file data.
