Cookies
We use a small, explicit set of cookies. The essential ones are necessary for the site to work; everything else is only activated if you authorise it in the cookie banner or on the “Cookies” control in the footer.
1. Essential (always on)
- yss_consent — stores your decision on optional cookies (valid 12 months).
- yss_currency — remembers your display currency (EUR / GBP / USD).
- OpenAuth session cookie (if you sign up) — keeps you logged in.
2. Analytics (optional)
Only when you accept the Analytics category. They let us see which landing converts best, where in the funnel visitors drop off, and the return on ad campaigns.
- PostHog (EU) —
ph_*cookies. Funnel and product analytics. We use a pseudonymous browser identifier. - Google Analytics 4 —
_ga,_ga_*,_gidcookies. Used to measure site use and campaigns. - Microsoft Clarity — site interaction and performance analytics.
- yss_utm — retains URL campaign parameters for 30 days to attribute a purchase to its traffic source.
3. Marketing (optional)
Only when you accept the Marketing category. These cookies optimise campaigns and measure ad conversions.
- Meta Pixel (Facebook / Instagram) —
_fbp,frcookies. Used for retargeting and so Meta Ads can learn which visitors become customers. Without these, ads still work, but with a worse cost per acquisition. - TikTok Pixel — on the US site only, for TikTok campaign attribution and optimisation.
4. Changing your decision
You can change or withdraw consent at any time through “Cookies” in the footer. You can also block or delete cookies in your browser settings.
5. Providers
PostHog, Google, Microsoft, Meta and TikTok process data under their own terms and international-transfer mechanisms. You can prevent this processing by rejecting the optional categories.
