Your files
Tools marked "Runs in your browser" process your files on your device. Files are not sent to us or to anyone else.
Some tools download extra code from this site the first time you use them, such as the HEIC image decoder. Nothing about your files is sent when this happens.
Cookies and analytics
We use Google Analytics to see which pages and tools are used, so we can improve them. It never receives your files, their names or their contents.
Until you choose Accept, and if you choose Decline, Google Analytics sets no cookies. It sends Google only anonymous signals that a page was viewed, with the page address and your browser type, and nothing that identifies you or links your visits together.
If you choose Accept, it also sets cookies (named _ga) so it can count returning visitors, and Google estimates your approximate location. You can change your choice at any time with Cookie settings at the bottom of every page.
Google signals and ad personalisation are turned off. See how Google uses this information.
Hosting
The site is hosted on GitHub Pages. GitHub may log technical information such as your IP address when you visit, as described in the GitHub Privacy Statement.
Tools that look things up
A few tools need to ask another service a question. They send only what is needed, straight from your browser:
The Password Checker sends the first 5 characters of your password’s SHA-1 hash to Have I Been Pwned, never the password itself. The Email DNS Checker sends the domain you enter to Cloudflare’s public DNS service, or Google’s if Cloudflare can’t be reached. The Currency Converter asks Frankfurter for the European Central Bank’s rates, sending only the currency and date. Tools that preview images from links you enter, such as the Email Signature Generator, load those images from their websites.
Data saved in your browser
Some tools may remember settings in your browser’s storage, and your cookie choice is stored there too. This stays on your device, and you can clear it in your browser settings.
