Cookie Policy
Last updated: October 2026
This page covers klar.im, the website. It does not cover the Klar app: the app is not a browser, sets no cookies, and never contacts a server about your mail. We set no advertising cookies and run no cross-site tracking, so the list below is short enough to read in full.
Cookies this site sets
Three, all functional. None of them is used to profile you or to follow you to another site.
- PARAGLIDE_LOCALE (set by us). Remembers whether you chose English, French or German, so a return visit opens in the language you picked. Written only once you switch language.
- crisp-client/… (set by Crisp IM SARL, France). The support chat keeps a conversation attached to you across page loads, so a reply reaches the person who asked. The widget loads only after you scroll or open the chat, and until then no Crisp cookie exists. See Crisp’s privacy policy.
- deck (set by us). Holds the password for one unlisted, password-protected page so you are not asked again for a day. It never appears if you have not opened that page.
Browser storage keys
Three keys, none of them a cookie. They keep the page the way you left it.
- klar-ref (sessionStorage, set by us). The ?ref= you arrived with, kept until you close the tab, so an App Store link can name where you came from. Written only when the address has one.
- klar-announce-dismissed:stalwart (localStorage, set by us). That you closed the announcement bar, so it stays closed.
- klar.demoReports (localStorage, set by us). A token for each report you send from the demo, so you can delete it from the same browser. See the demo section of the privacy policy.
Measurement, which uses no cookies
Two pieces of our own software tell us how the site is doing. Neither one identifies you, neither uses a cookie, and neither stores anything in your browser.
- Page views and three kinds of anonymous events, counted by our own analytics software (signals.klar.im) on our own server in Paris. The events say which homepage version was shown, whether the inbox-tax calculator was used and whether an App Store link on any page was clicked. Cookieless by design: it stores nothing in your browser and builds no visitor identifier.
- Session replay, by our own software (signals.klar.im) on our own server in Paris, which shows us where people get stuck in the on-page demo. It records the text and layout of the page, your clicks and your scrolling, never what you type, never a message you drop into the demo and never text that looks like an email address or a long number. It keeps no identifier beyond the day: a replay and its clicks carry a code worked out from your network address and browser that changes every day, so they cannot be linked to you on another day. Replays are deleted after 14 days. It honours Do Not Track and Global Privacy Control: turn either on in your browser and nothing is recorded.
Why there is no banner
A consent banner exists to ask about storing things in your browser and following you between sites. We store nothing beyond the functional items above, and follow nobody. So there is nothing for us to ask you about, and a banner would be theatre.
How to refuse any of it
You do not have to take our word for the list. Open your browser’s developer tools, look at Storage, and check it against this page.
- Never open the support chat, and no Crisp cookie is ever set.
- Turn on Do Not Track or Global Privacy Control in your browser, and session replay records nothing.
- Block or clear cookies for klar.im in your browser settings. The site keeps working; it will just forget your language.
