Cookies are small text files stored on your device when you visit a website. They help the site function properly (e.g. by keeping you logged in) and can remember preferences. Related technologies covered by this policy include localStorage and sessionStorage, which are similar browser-side storage mechanisms.
The cookies required for the Platform to work — authentication and security — are strictly necessary and always active. In addition, and only with your consent, we use Google advertising and measurement cookies (loaded via Google Tag Manager) to measure how many visitors start a trial after seeing our advertising. These are set only if you choose “Accept all” in our cookie banner, and you can decline or withdraw your consent at any time. Under Article 5(3) of the ePrivacy Directive the strictly-necessary cookies do not require consent; the advertising and measurement cookies do, and we obtain it through Google Consent Mode v2.
| Cookie | Set by | Purpose | Type | Duration |
|---|---|---|---|---|
| __session | Clerk | Authenticated session token | Essential | Session |
| __client_uat | Clerk | User authentication timestamp | Essential | Session |
| __clerk_db_jwt | Clerk | Short-lived session JWT | Essential | Session |
| __clerk_* (other) | Clerk | Authentication / CSRF protection | Essential | Session |
| sp_cookie_consent | Self Property (localStorage) | Records your cookie choice | Essential | Persistent |
| _gcl_au | Google (via Google Tag Manager) | Google Ads conversion linker — measures trial sign-ups from our ads | Advertising (consent) | 90 days |
| IDE, NID, test_cookie, _gcl_* | Google / DoubleClick | Ad-conversion measurement — set only if you choose “Accept all” | Advertising (consent, third-party) | Up to ~13 months |
We also use your browser's localStorage to remember UI preferences so the Platform feels continuous across visits. This data stays on your device and is never transmitted to our servers. The keys we set include:
selfproperty-language— your chosen interface language (en / fr / nl)selectedBuildingId— the building currently in viewlastSeen_announcements, lastSeen_maintenance, lastSeen_meetings, lastSeen_documents— timestamps used to calculate unread badgeshasSeenManagerWelcome, hasSeenOwnerWelcome, hasSeenTenantWelcome— dismissal state for the first-time welcome modalpwaInstallPromptDismissed— dismissal state for the "Install this app" promptYou can clear local storage at any time through your browser's site-data settings.
We use Google Ads with Google Consent Mode v2 to measure how many visitors start a trial after seeing our advertising. It is loaded through Google Tag Manager and only sets cookies after you accept them in our banner; if you decline, Google receives only aggregated, cookieless signals and no advertising cookies are stored on your device. We do not use Google Analytics 4, the Meta pixel, the TikTok pixel, Hotjar, session-replay, or social-media tracking, we do not display advertisements on the Platform, and we never sell your data.
You can accept or decline non-essential cookies at any time through our cookie banner — clear your browser's site data for this site to see it again — and you can manage or block cookies in your browser settings. Note that blocking the strictly-necessary cookies will prevent you from logging in or using the Platform.
We may update this Cookie Policy from time to time. Changes will be shown here with an updated date. Where we use non-essential cookies, we ask for your consent beforehand through our cookie banner, which uses Google Consent Mode v2 and defaults to “denied” until you accept.
