7. Cookies

Technically necessary and without consent: the cookie architektonik_session keeps you logged in after you sign in (at most 12 hours). The cookie architektonik_lang stores the selected language (12 months). We store your choice in the cookie notice in your browser’s local storage (architektonik_consent); it does not leave your device.

Statistics: for audience measurement we use Google Analytics 4, integrated via Google Tag Manager. Google Analytics sets the cookies _ga and _ga_<ID> (storage period up to 2 years) and may transfer data to the USA (see section 4). Full IP addresses are not stored. We do not use advertising functions or cookies for advertising purposes. We rely on our legitimate interest in improving the website (Art. 31 para. 1 FADP). On your first visit, a notice points out these cookies.

Objection: you can decline the statistics at any time, in the notice shown on your first visit or via «Cookie settings» at the bottom of every page. After that we no longer load anything from Google and delete the Google Analytics cookies in your browser. Your choice applies for 12 months.
