Privacy Policy

1. What we collect

Downloads on this site use a unified YofMo account: the account, password and login session are all provided by YofMo (yofmo.com). C-Slim stores no passwords and has no registration or login system of its own; a free YofMo account is required to download. Beyond that, we store only two preferences in your browser's local storage:

• cslim-theme — remembers whether you chose the dark or light theme;
• cslim-lang — remembers whether you chose the Chinese or English interface.

Both values live only in your own browser; C-Slim never reads them and never sends them to any server. You can delete them any time by clearing site data in your browser settings.

2. The desktop tool itself

Every C-Slim script runs on your local machine and sends no data, logs, or telemetry to any server. Installation packages are distributed through our official channel.

3. Cookies

This site serves no ads and includes no advertising or analytics scripts. The login state required for the download gate is set by YofMo as the yof_session cookie (domain .yofmo.com, HttpOnly, 7 days). C-Slim only uses its presence to decide whether you are signed in; it never reads or stores its contents. Signing out at yofmo.com clears it.

4. Hosting and logs

This site is hosted on Cloudflare Pages. As a CDN, Cloudflare may record routine information such as your IP address, User-Agent, and visit time for security and operations. These logs are handled by Cloudflare under its privacy policy; the C-Slim project does not separately collect or analyze them. Package delivery and download counting are handled by a Cloudflare Worker (cslim-api), which only accumulates a download count and records no personal information.

5. Children's privacy

This tool is aimed at Windows desktop users for managing local disk space. It is not directed at children under 13 and does not knowingly collect information from children.

6. Changes to this policy

If this privacy policy changes, we will update the "Last updated" date at the top of this page. Significant changes will also be noted in the project changelog.
