When you open a page

This website is delivered by Cloudflare. To send you the page and to protect the site from attacks, Cloudflare processes technical data that every browser sends, such as your IP address, browser type and the page you request. We do not use this data to identify you. Legal basis: our legitimate interest in running a secure website (Art. 6(1)(f) GDPR). Cloudflare, Inc. is a US company, so this data may be processed outside the EU; it is kept according to Cloudflare’s privacy policy.

Google Analytics

We use Google Analytics 4 to count visits and to see which pages buyers read. It sets the cookies _ga and _ga_HWKGV9N1E7, which are kept for up to 2 years.

Visitors in the EU, the EEA, the UK, Switzerland and related territories (such as the French overseas territories, Gibraltar, the Channel Islands, Monaco and Andorra), and visitors whose location cannot be determined: Google Analytics only starts after you click “Accept” (Art. 6(1)(a) GDPR, § 25(1) TDDDG). Until then no Google script is loaded. Your location is determined from the IP address of your connection; if you use a VPN, the location of the VPN counts. You can withdraw at any time under “Cookie settings” at the bottom of every page; the cookies are then deleted and the page stops sending data at once. Withdrawing does not affect the lawfulness of processing before the withdrawal.

Your choice is stored in your browser (entry cq-ga-consent, which only records “accepted” or “declined”). It is deleted when you clear your browser data.

Visitors in other regions: Google Analytics starts when the page loads.

Google does not log or store IP addresses of users in the EU, Switzerland or the UK. Event data is deleted after 2 months and user-level data after 14 months.

Data may be processed on Google servers in the USA. Google LLC is certified under the EU-U.S. Data Privacy Framework.

Email and phone inquiries

If you email or call us, we use your details only to answer your inquiry and to prepare quotations (Art. 6(1)(b) GDPR). We delete them when they are no longer needed, unless the law requires us to keep them.

Your rights

You can ask us for access to your data, for correction or deletion, for processing to be restricted or stopped, or to receive your data in a portable format. You can withdraw consent at any time, and you can complain to a data protection supervisory authority. Write to Rick_Lee@chec.tw.
