Cookie Policy
Last updated: September 14, 2026
This section lists the cookies and similar technologies used on the marketing website (wonderguest.app) and in the WonderGuest application (app.wonderguest.app and the mobile apps).
Marketing website
- Strictly necessary: a single cookie, wg_market, which keeps the currency shown for pricing for the session, or the one chosen with the currency selector for one year. The language is carried by the page address (/fr, /en…).
- Audience measurement: Plausible Analytics, Vercel Analytics and Vercel Speed Insights. None of them sets a cookie or tracks you across other websites.
- Attribution: a first-party cookie (wg_attribution, 30 days) that records the campaign parameters of the link you arrived from (utm tags, referral code, gclid, fbclid, ChatGPT Ads oppref and oai_*) so that a later sign-up can be attributed to that campaign.
- Advertising: the Meta Pixel, which loads on every page of the marketing website. It sets the _fbp and _fbc cookies and sends the pages you view, your IP address and browser data to Meta Platforms, so that we can measure our Facebook and Instagram campaigns and build advertising audiences. Meta may combine this data with your Meta account under its own privacy policy.
Application
- Session and preferences: your authentication session, language, theme and onboarding progress are kept in local storage on your device.
- Product analytics: PostHog, hosted in the European Union, identifies your session with a cookie or a local storage key and records the actions you take in the application.
Your choices
You can block or delete cookies in your browser settings. The website works without the attribution and advertising cookies. To limit how Meta uses the data collected through the pixel, adjust your Meta ad preferences. Our websites do not currently respond to “Do Not Track” or Global Privacy Control browser signals.
