Summary: What This Policy Means for You

In short: our tools run in your browser and generally send nothing to our servers; the site itself uses standard analytics and advertising cookies that you can block; and we do not sell personal data. This page explains each statement in detail, including your rights and how to contact us.

Data We Do Not Collect (Because Tools Run Locally)

Most tools - converters, counters, calculators, encoders, SEO checkers - process everything in your browser using JavaScript. The text you paste, the files you select and the results you see never leave your device. That is a design decision, not a limitation: we cannot see, store or lose data we never receive. A few tools that need server-side processing (if any) state this explicitly on their page, and any data they handle is covered by the sections below.

Data We May Collect Through the Site

Server logs - IP address, user agent, requested URL and timestamps, retained briefly for security and abuse prevention
Analytics - aggregate usage statistics (pages visited, approximate region, device type) used to improve the site
Advertising - cookie-based ad delivery and measurement by third-party networks, where ads are shown
Contact correspondence - the content you send us by email, kept only as long as needed to resolve your case

How We Use This Data

Server logs protect the site from abuse and diagnose outages. Analytics tell us which pages deserve updates and which tools are failing. Advertising keeps the site free. Contact data resolves your request. We do not build profiles of individual visitors, do not combine analytics with contact data, and do not sell personal information to anyone.

Your Rights and Choices

Block cookies - set your browser to reject third-party cookies or use private mode; tools keep working
Opt out of analytics - install a privacy blocker or use the browser's do-not-track settings
Access and deletion - email us to request what we hold about you (normally only correspondence) and we will provide or delete it within 30 days
Children - the site is not directed at children under 13 (or 16 where local law says so) and we do not knowingly collect their data
International transfer - data processed by service providers may cross borders; we only use providers that commit to adequate protection

Cookies and Similar Technologies

First-party cookies are used only for essential site functions. Third-party cookies may be set by analytics and advertising providers; blocking them does not break the tools. The most common providers on this site are Google Analytics (usage statistics, aggregatable) and Google AdSense (ad delivery and fraud prevention); both offer opt-out mechanisms at their official sites.

Data Retention and Security

Server logs are deleted on a rolling schedule (normally under 90 days). Correspondence is kept until the case closes plus a short audit window. Access to any stored data is limited to the maintainers who need it, transmitted over HTTPS, and protected by standard access controls. We review these practices when our stack changes.

Changes to This Policy

We update this page when practices change, with the new date at the top. Material changes are highlighted and, where required, announced. Continued use of the site after an update means you accept the revised policy; you can always stop using the site instead.

Contact for Privacy Questions

Privacy questions and data requests go to wy18850939@gmail.com or 18850939@qq.com with 'Privacy' in the subject. We respond within 30 days, usually faster, and never require payment for a data request.
