1. Introduction
This Privacy Policy explains how 器傳 QICHUAN ("we", "us", or "the Website", accessible at toolregula.com and its sub-domains) handles information and cookies when you visit the Website. The Website provides engineering calculation tools for plastics and polymer processing.
2. Information We Collect
The Website is designed to operate without requiring you to create an account or submit personal information. Calculations you perform are executed in your browser and are not stored on our servers. We do not knowingly collect names, email addresses, or other personally identifiable information unless you voluntarily send it to us (for example, by contacting us via email).
3. Cookies
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work, to improve efficiency, and to provide reporting information. We may use the following categories of cookies:
- Essential cookies — required for the basic operation and security of the Website. These do not require consent.
- Preference cookies — used to remember settings such as input values or display preferences, so the tools are more convenient to use.
- Analytics cookies — if enabled, these help us understand how visitors use the Website (for example, which tools are most used) on an aggregated, anonymous basis.
4. Third-Party Services
The Website relies on third-party providers that may set their own cookies or receive technical data (such as your IP address and browser type) when serving content:
- Cloudflare — used to host and deliver the Website and to protect it against malicious traffic.
- Google Fonts — used to load the typefaces used on the Website.
These providers process data in accordance with their own privacy policies, over which we have no control.
5. Managing Cookies
You can control and delete cookies through your browser settings. Most browsers allow you to refuse or remove cookies; however, please note that disabling essential cookies may affect how parts of the Website function.
6. Data Retention & Security
Because we do not maintain user accounts or a personal-data database, we do not retain personal information beyond what is technically necessary to operate and secure the Website. We take reasonable measures to protect any data that is processed.
7. Children's Privacy
The Website is intended for professional and academic use and is not directed at children. We do not knowingly collect personal information from children.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
