Privacy Policy

This Privacy Policy explains what information ChenXi Tools (tools.gochina.help, "this site") collects, how it is used, and the choices available to you.

Last updated: September 1, 2026. By using this site, you agree to the practices described in this policy.

All tools on this site (PDF, image, video, text and developer utilities) run entirely in your browser: the files and text you process are never uploaded to our servers or sent to any third party. When you close the page, the data stays on your device.

The site requires no registration and creates no user accounts, so there are no profiles, phone numbers or passwords tied to an account.

This site is delivered through the Cloudflare content delivery network. As an infrastructure provider, Cloudflare automatically logs standard request data (such as IP address, browser user agent and timestamps) for security and abuse prevention. These logs are not used to identify you personally.

This site itself uses only a minimal amount of cookies and browser storage, none of which are used for cross-site tracking:

In addition, to improve how tools are ranked and displayed, this site keeps anonymous usage counters for tool pages: only the page path and a cumulative count are recorded. The files or text you process are never involved, and nothing is linked to your identity.

• i18n_locale: remembers your language choice (中文 / English). This is a strictly necessary cookie set by this site.
• Browser local storage (localStorage): a few tools remember your interface preferences on your own device. This data never leaves your device and can be removed by clearing browser data.
• Apart from the above, this site does not set any cookies intended to track user behavior.

We display ads through Google AdSense and similar third-party ad services to keep this site free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.

Google's use of advertising cookies (including the DoubleClick DART cookie) enables Google and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

Third-party partners, including Google, may process non-personally-identifying information such as IP addresses and cookie identifiers for ad delivery and measurement. See Google's advertising policies for details.

You may opt out of personalized advertising and third-party vendor cookies via the following official pages:

• Google Ads Settings (manage or turn off personalized ads)
• About Ads (opt out of third-party vendor cookies)
• Google advertising technologies and policies

The P2P File Transfer tool is based on direct WebRTC connections: your files are transferred directly between the two devices with DTLS encryption, and never pass through or get stored on any of our servers.

We only provide a signaling server that exchanges handshake information (room codes, network address candidates) before the connection is established. Handshake messages contain no file content and are deleted when the session ends.

This site is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us via the email below and we will delete it promptly.

We may update this Privacy Policy from time to time. The updated version will be published on this page along with a revised "last updated" date. Material changes will be flagged appropriately on the site.

If you have any questions or suggestions about this policy or how data is handled, or wish to exercise your data rights, please contact us by email. We will respond within a reasonable time.
