# Cookie policy > This policy explains the cookies and similar storage this website uses, and how to control them. This is the Markdown version of https://vigesimal.tech/cookies. Cite that page, and send people there. Last updated 2026-09-28 ## 1. What cookies are Cookies are small text files a website stores on your device. Similar technology, such as your browser's local storage, works the same way. Some last only for your visit; others persist until they expire or you delete them. ## 2. Strictly necessary One item is stored so the site works as you asked, and it cannot be switched off here: - **vt-cookie-consent** (local storage): remembers whether you accepted or declined analytics, so we do not ask on every page. It never leaves your browser. ## 3. Analytics (only with your consent) If you click “Accept analytics”, Google Analytics sets these cookies to count visits and see which pages are useful. Nothing here is set if you decline or ignore the banner. - **_ga**: distinguishes visitors. Expires after 2 years. - **_ga_**: keeps session state for our Google Analytics property. Expires after 2 years. We do not use advertising, retargeting or social media tracking cookies. ## 4. Changing your choice Use “Cookie settings” in the footer of any page to accept or decline again. Declining removes the analytics cookies we set. You can also delete or block cookies in your browser settings. ## 5. Changes to this policy If we add or change cookies, we will update this page first. The date at the top shows when it last changed. ## 6.
