What is a cookie?
A cookie is a small text file stored on your device when you visit a website. Cookies allow the site to remember certain information, such as your language preference or session. Your browser's local storage and session storage play the same role; they are described here along with cookies.
What useservice.app stores on your device
Running the site
- Language preference (
service-docs-locale, local storage) — remembers the language you read the site in, so you are not redirected again. Kept until you clear the site's data. - First page of the visit (
service-first-touch, session storage) — the page you arrived on, the site you came from and the campaign parameters in the address, attached to your message if you use the contact form. Cleared when the tab is closed.
Audience measurement and sales follow-up (PostHog)
We use PostHog (PostHog Inc., data hosted in the European Union, in Frankfurt) to measure the site's audience, record browsing sessions with form fields masked, know where visits come from, and link a professional's visits to their establishment or email address. These trackers are set from your first visit:
- Cookie
ph_<project identifier>_posthog— a random identifier for your browser and your session. Duration: 365 days. - Local storage and session storage, under names starting with
ph_— the same information, and the state of the current session.
What PostHog collects, why, and how long we keep it is detailed in Section 13.2 of our privacy policy. PostHog is loaded on useservice.app only, never in the back office, the app, the booking widget and pages, or on restaurants' websites.
What we don't use
- Advertising or retargeting cookies
- Cross-site tracking cookies
- Third-party tracking pixels (Facebook, Google Ads, etc.)
- Google Analytics
Managing your preferences
You can delete or block cookies and site data in your browser settings: the site works without them, except for remembering your language. To object to audience measurement or to your visits being linked to your establishment, write to us atsupport@useservice.app.
