Privacy Policy
Last updated: July 26, 2026
1. Tool data
The text, files, or images you enter into a U5F tool are processed locally in your browser using standard web APIs (such as the Web Crypto API or the Canvas API). That content is not uploaded to our servers and we do not store, log, or have access to it.
2. Information we do collect
Like most websites, we may collect standard technical information when you visit U5F — for example, your browser type, device type, approximate location derived from IP address, pages visited, and referring site — through analytics tools such as Google Analytics or a comparable privacy-respecting alternative.
3. Cookies
U5F uses cookies or similar local storage to remember your theme preference (light, dark, or system) and, if analytics are enabled, to distinguish visitors. You can clear or block cookies through your browser settings; doing so may reset your theme preference.
4. Advertising
U5F may display ads served by third-party ad networks (such as Google AdSense). These networks may use cookies or device identifiers to serve relevant ads and measure performance. We do not share the content you enter into a tool with advertisers, because that content never reaches our servers in the first place.
5. Third-party links
U5F may link to third-party sites. We aren't responsible for the privacy practices of sites we don't operate.
6. Children's privacy
U5F is not directed at children under 13, and we do not knowingly collect personal information from children.
7. Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with an updated revision date.
