TechCrz has no accounts, no forms, no ads and no analytics, and this site sets no cookies.
What you type
The tools run in your browser. The text, numbers, passwords and files you enter stay in the page on your device. They are not sent to this site or to anyone else, and they are not saved. The tool pages contain no code that makes a network request with your input.
The file checksum tool reads the file you choose in your browser only. The file is not uploaded.
What is stored on your device
If you use the light and dark switch, your choice is kept in your browser's local storage so the page remembers it. Nothing else is stored. You can clear it in your browser settings at any time.
Cookies, analytics and advertising
This site sets no cookies. It has no analytics and shows no ads. This page will be updated before ads or analytics are added.
Server logs
The site is hosted on Cloudflare Pages. Cloudflare processes each request for a page and may keep standard server logs, such as the address of the request, the time and the page asked for. See the Cloudflare privacy policy.
