Privacy Policy

Last updated: May 2026

The short version: Your files never leave your device. ClientSide does not collect, process, transmit, or store any file you drop on this site. This is not a legal formality — it is a technical fact baked into the architecture.

How ClientSide works

ClientSide is a static website hosted at clientside.sh on Cloudflare Pages. When you visit, your browser downloads HTML, CSS, and JavaScript files from Cloudflare's CDN. After that, all file processing happens entirely inside your browser tab:

  • The File API reads your files directly from your disk into browser memory (RAM).
  • JavaScript processes the file data locally — no data is sent anywhere.
  • The processed file is written directly from browser memory to your Downloads folder.

No file data is ever sent over the network. There is no upload endpoint. Cloudflare, which hosts this website, has no ability to receive your files because no code on this site sends them.

What we do not collect

  • We do not collect your files or any content within them.
  • We do not collect metadata, GPS coordinates, or any information extracted from your files.
  • We do not require an account, email address, or any personal information.

Third-party scripts

ClientSide uses open-source JavaScript libraries served from jsDelivr CDN on relevant pages. These libraries run entirely in your browser and never receive your file content. jsDelivr may log standard CDN access data (IP address, timestamp, resource requested) per their own privacy policy.

Advertising

This site displays ads served by Google AdSense. Google may use cookies and similar technologies to show personalised ads based on your browsing activity, in accordance with Google's Privacy Policy. You can opt out of personalised advertising via Google's Ad Settings or by visiting aboutads.info. Ad serving is handled entirely by Google — ClientSide does not receive or store any data collected for advertising purposes.

Hosting

This site is hosted on Cloudflare Pages. Cloudflare may retain standard web server access logs (IP address, browser, pages requested) as part of CDN operation. Cloudflare never receives or processes your files.
