Privacy policy
CrabTools is a free suite built by Crabsoft. It asks for no accounts or personal data to use its tools.
Your files
The tools on this site process PDFs, images and QR codes inside your browser. Those files, and any WiFi passwords you type, are not sent to our servers or stored. Your files never leave your device.
Cookies and tracking
CrabTools uses no cookies, analytics, tracking pixels, advertising or third-party scripts, so you will not see a cookie banner. Fonts are served from this same site, with no connection to Google or any other service.
Technical data
As with any website, the infrastructure that hosts it may log technical data about visits, such as the IP address and browser type, for operation and security. It is used only for that purpose.
API
CrabTools also offers an API for anyone who chooses to use it directly. In that case the data sent is processed to produce the response and the application does not store it.
Links to Crabsoft
Links to crabsoft.dev take you to another site with its own terms. Anything you send us when contacting us there is handled on that site.

If you have questions about this notice, write to us through Crabsoft.
Third parties and licenses
CrabTools relies on these open-source components. All of them run from this same site and send no data to their authors.
