Local storage
In addition to cookies, our website also uses localStorage technology in the browser. This serves as a fallback mechanism to store your cookie preferences (cookie_consent_v2) in case cookies are not available.
With your consent, PostHog also keeps a local storage key ph_<project key>_posthog with the same data as its cookie, including your browser's identifier, your profile details and where you first came from. If you open the blog from a PostHog toolbar link (an address ending in #__posthog, used only by our team), PostHog's script saves the toolbar settings in local storage (_postHogToolbarParams).
With your consent, we also keep your first visit in local storage (cc_first_touch) for at most 13 months, and we delete it on any visit without consent.
Apart from cc_first_touch, our own localStorage entries (the copy of your cookie choice, and whether you have closed a banner or panel or collapsed the table of contents) stay in your browser; we do not send them to our server. When you make a cookie choice, the banner reports it once to our server, together with the page, the language and a random code kept for this tab only in session storage. PostHog's entry is read by PostHog's script, which sends the data it holds to PostHog with your page views.
