Privacy Policy
Effective 24 October 2026
This policy explains what information terasystem.app collects, why, and the choices you have. We collect very little, so it is short.
Who we are
This site is operated by TeraSystem. Contact for privacy questions and requests: [email protected].
Site analytics
We use Cloudflare Web Analytics to count page views. It does not use cookies, does not follow you across other sites, and reports only aggregate statistics such as pages viewed, referring sites, country and browser type.
Hosting and security
The site is delivered through Cloudflare, which processes your IP address and request information to deliver and protect the site.
Our own server keeps an access log with the time, the requested address, the referring page and your browser type. It does not record your IP address. These logs are kept for about two weeks and then deleted.
If you email us, we receive your email address and message through Cloudflare Email Routing and store them in Gmail (Google). Replies are sent through Brevo. We use them only to answer you.
Your browser
Your language choice is saved in your browser’s local storage so the site remembers it. It is never sent to us.
What we do not do
We do not sell personal data, show advertising or use advertising trackers.
Your rights
Under Taiwan’s Personal Data Protection Act you may ask to inquire about, review or copy the personal data we hold about you, to supplement or correct it, to stop its collection, processing or use, or to delete it. Send requests to [email protected].
Changes
If this policy changes, we will update this page and the effective date above.
