Privacy Policy
This policy explains what information Jianpu Studio collects, why we collect it, and the choices you have. It applies to every page on jianpu.mytoolmasters.com.
The short version
- Data you type into a tool stays in your browser and is never sent to us.
- We use privacy-friendly analytics to understand which pages are useful.
- We only collect feedback details when you choose to submit them.
- We do not sell personal information.
Information we do not collect
Tool inputs, uploaded files and calculation results remain in your browser memory. We have no server endpoint that receives them, so we cannot read, store or share them.
Information we do collect
Like most websites, our hosting provider records standard technical logs (IP address, browser user agent, requested URL, timestamp) for security, abuse prevention and performance monitoring. These logs are retained for a limited period.
Analytics
We use Cloudflare Web Analytics, a cookie-less, privacy-first measurement service that reports aggregated page views. If Google Analytics 4 is enabled on this site, it collects aggregated usage data such as page views, approximate region and device type.
Advertising and affiliate links
This site currently shows no third-party advertising.
This site currently contains no affiliate links.
User feedback
If you use the feedback widget, we store your rating, optional message, the page identifier, your browser user agent and IP address. We use this to improve tools and to prevent spam. Feedback is never published with your identity.
Third-party services
Our hosting and analytics providers process data on our behalf under their own privacy terms. Links to external websites are governed by those websites' policies.
Data retention
Technical logs and feedback records are kept only as long as needed for the purposes above, then deleted or aggregated.
Your rights
Depending on where you live, you may have the right to access, correct, delete or restrict the processing of your personal data, and to object to processing. Contact us to exercise these rights.
Children
This site is not directed at children under 13, and we do not knowingly collect personal information from them.
Changes to this policy
We may update this policy when our services change. The latest version is always available on this page.
