Privacy Policy

The tools currently provided by QR9.NET run in the browser. Text, files, keys, images, or other content you process are not uploaded to QR9.NET servers as tool computation input.

If a page needs to load model files, scripts, styles, or images, the browser still sends network requests for those resources. Those requests do not need to submit your tool input as the request body.

Shared computers, unknown browser extensions, the system clipboard, and device security can still affect the risk of handling sensitive information.

Some tools store interface state, temporary results, or local history in your browser, such as JSON tool history or metronome settings.

You can clear site data, cache, and local storage from your browser settings.

Pages with advertising enabled may use Google AdSense. Google and its advertising partners may use cookies, local storage, or similar technologies to process IP addresses, device and browser information, page URLs, advertising identifiers, and ad impression or interaction data.

This information is used to deliver ads, control frequency, prevent invalid traffic, personalize ads where permitted and consented to, measure performance, and secure advertising services. Google and its partners may process this information outside your country or region.

Google AdSense is not used to read local content you process in tool inputs, file selectors, or key fields. This site may disable advertising on pages intended for highly sensitive content.

Where required by applicable law, this site uses a Google-certified consent management platform to request your choice before consent-dependent advertising storage or personalized ads are used. If you refuse or withdraw consent, advertising features may be limited and non-personalized or limited ads may still appear.

You can review or withdraw your choice through the privacy options shown on the site, block or delete cookies in your browser, and manage Google ad personalization in My Ad Center. Blocking cookies may affect some advertising or site functions.

When you contact us by email, we receive the email address, message, and attachments you choose to provide. That information is used only for feedback, troubleshooting, or security response.

This site may link to filing lookup pages, open-source projects, or other third-party websites. Those websites have their own privacy policies and data handling practices.

Privacy questions or rights requests can be sent to [email protected]. This policy was last updated on July 31, 2026.
