Cookie policy
Last updated: 26 October 2026
Yerjung uses only the cookies it needs to work. We do not use advertising cookies, analytics cookies or third-party trackers, so there is nothing to opt out of.
What we set
- ps_session: keeps you signed in. Essential. Removed when you sign out or after it expires.
- ys_shop: remembers which shop you are working in if you belong to several. Essential.
- ps_as: lets an administrator view a shop on its owner's behalf, and only for administrators. Essential.
- ys_gstate: a short-lived (10 minutes) safety check while signing in with Google. Essential.
- lang: remembers your language choice for a year. A preference you set yourself.
Browser storage
We also keep a few small settings in your browser's local storage, such as that you closed a tip, how you sorted your product list, and that you closed the cookie notice. They never leave your device.
Third parties
If you choose to sign in with Google, you go to Google's own page, which sets its own cookies under Google's policy. Fonts are served from our own site.
Controlling cookies
You can delete cookies in your browser settings or block them. If you block the essential ones you will not be able to sign in. Because none of our cookies are optional tracking, we only show a small notice, not a consent form.
If this changes
If we ever add analytics or anything else that needs your consent, we will ask first, before it runs, and update this page.
