Privacy
The short version: your files are never sent anywhere, because there is nowhere for them to be sent.
Files you compress
ShrinkWrit has no backend. Compression runs inside your browser using WebAssembly. Your file is read from disk by the page, processed in memory, and written back out as a download. It is never uploaded, never stored, and never transmitted — not to us, not to anyone. Closing the tab discards everything.
Because there is no server component, this is a structural property rather than a policy commitment. You can verify it: open your browser’s network inspector while you compress a file, or disconnect from the internet after the page loads and compress offline.
What we do not collect
- File contents, file names, file sizes, or file types
- Anything derived from a file you process, including hashes
- Accounts, email addresses, or any information you would have to give us
Analytics
Any analytics used on this site are limited to page-level traffic measurement and are never permitted to observe the compression tool, its inputs, or its outputs.
Advertising
This site is supported by display advertising. Ad code runs strictly outside the compression path and has no access to files you process. Advertising partners may set cookies and process data under their own privacy policies; see your browser’s cookie controls and your ad settings with those providers to manage this.
Hosting
The site is served as static files from a CDN. As with any web request, the host receives standard server log information (IP address, user agent, requested page) for the pages themselves. No request is ever made that carries the contents of a file you compress.
