Privacy and data instructions

Input and results

Calculation and text tools do not upload input and results to the server, write to URLs, log to analysis events, or save to local storage. Refreshing, closing, or switching tool pages will reset the input. The Copy button writes the result to the system clipboard when clicked; clipboard saving and synchronization is determined by the operating system and the software you are using.

Sharing includes only the public page title, description and a link without parameters, never tool inputs, results or files. QR codes are generated in your browser. Public page information is passed to the system share sheet only when you choose system sharing.

Images, PDFs, compressed packages, audio and video, recognition results, interpreter codes and local database files are only processed in the memory of the current page and background thread, and are not uploaded or written to local storage. The download is initiated by you and the original file will not be overwritten. Runtime libraries and open source models are loaded on demand from this site, and ordinary HTTP cache may retain these public program files without your input.

You must choose the sharing range for screen recording. It only records the screen and does not collect microphone or system sound. Text reading only uses device speech marked as local by the browser; Internet speech is not used in the absence of local speech. Leaving or clearing a tool stops the related tasks and frees the results from the page.

Proactive IP and connection detection

After clicking the detection button, the page will query the current connection information and measure the request time. Click the details button to query the ASN, network organization and city. Cloudflare, our host, handles the connection IP and provides request metadata such as country code and protocol. We do not call other IP intelligence services, do not request device location permissions, and do not provide arbitrary IP lookups.

The detection code does not write to the database, does not record IP logs, does not cache individual detection responses, and does not save query history. Results are only retained in the current page memory; clearing, refreshing, closing, or switching tool pages will clear the results. Cloudflare's handling of network requests remains subject to the privacy policy listed below; this is not a promise that "IPs never pass through the server."

Active DNS lookup

DNS, Mail DNS, Reverse Lookup, CAA, and DNSSEC tools request Cloudflare public DNS directly from the browser only after a click query. The queried domain name (reverse name converted from IP during reverse query) and record type are sent through the HTTPS request parameters of the service; Cloudflare will receive the query name and connection IP. Please do not fill in internal or sensitive domain names.

This site does not save query history, put input into page URLs or count events. Processing of query data appliesCloudflare Public DNS Privacy Notice。

Native preferences

Theme and language selections are saved in the current browser via localStorage, and the sidebar expanded state is saved only in page memory. These preferences do not cover tool input and output and can be cleared through your browser's site data settings. When you visit for the first time, you can recommend versions according to the browser language, but you will not be forced to jump.

After you open a tool, Frequent saves its ID in this browser’s localStorage, with the most recently opened tools first. It does not store inputs, results, file contents or query parameters, and does not upload or sync this list across devices. Clear this site’s browser data to remove these records.

Network loading and performance statistics

Cloudflare provides web and static resource distribution, handling the network requests required to load the pages. The online page will load the Cloudflare performance statistics script to observe page access and loading performance; this site does not connect the tool input or output to this statistics.

Cloudflare's statistics collection scope is based onData collection documentationandprivacy policyshall prevail. The page is not currently loading ads, nor is it requesting external fonts.

External links and examples

Reference materials need to be clicked to open an external website. The URL tool does not access the entered URL, and the Markdown preview does not automatically load external images. The examples are demo content; it is still recommended to use desensitized samples first and confirm the URL before using any web tools.
