Privacy Policy
Last updated: 18 September 2026
The short version
Everything you paste, type or drop into our tools stays in your browser. The tool code executes locally on your device; there is no application server that could receive, store or log your content. What we do collect is minimal, and it is listed below in full.
1. Your content
Text you paste, colors you pick, UUIDs you generate and images you compress are processed entirely in your browser tab (JavaScript, Canvas, Web Crypto). They are never transmitted by our code to any server, and closing or reloading the page discards them. We have no access to them at any point.
2. Cookies and local storage
The tool pages themselves do not set first-party cookies and do not use localStorage to profile you. Your browser may keep the page in its regular HTTP cache for faster reloads.
3. Third-party advertising
This site displays advertising served by Google AdSense. When you visit a page, Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.
- You may opt out of personalised advertising by visiting Google Ads Settings.
- You can also opt out of third-party vendor cookies for personalised advertising at aboutads.info/choices.
- Where required (for example in the EEA/UK), a consent banner will request your permission before advertising cookies are set, and you may withdraw consent at any time.
4. Analytics
We may use privacy-conscious, cookieless aggregate analytics (page counts and referrers only) to understand which tools are useful. No cross-site tracking identifiers are used for analytics.
5. Hosting and server logs
Like every website, our static hosting provider may record standard server logs (IP address, user agent, requested page, timestamp) for security and abuse prevention. We do not control or additionally exploit these logs.
6. Children
The site is a general-audience utility and is not directed at children under 13. We do not knowingly collect personal information from children.
7. Changes and contact
If this policy changes materially, the "last updated" date above will change. Questions can be sent to hello@lanrensoft.cn.
