Cookie policy.
The cookies and similar technologies NJYN uses, what they do, and how you control them. We use as few as we can get away with — today only a single session cookie.

What cookies are
A cookie is a small piece of text a website stores on your device. We also use similar local technologies — localStorage and session storage — and we treat them all the same in this policy: as "cookies".
Some are set by NJYN directly ("first-party"), others by services we embed ("third-party"). Some live only for a session, others persist. The full current list lives in section 3.
Categories
We group cookies into four categories. Strictly-necessary cookies are always on — without them the site cannot function. Everything else is opt-in. Today only the strictly-necessary category is in use. The other three are listed as placeholders so you can see what they would do if we ever enable them. They are non-interactive on this page.
Strictly necessary
Keeps you signed in and authenticates each request. Cannot be disabled — without it you cannot use NJYN.
Functional
Would remember preferences like theme or sidebar state across sessions. Today these live only in your browser's localStorage and are never sent to us.
Analytics
Reserved for privacy-friendly, EU-hosted analytics. Currently not in use — we ship no analytics tracker.
Marketing
Reserved for advertising measurement. Currently not in use — we ship no marketing or ad-tech tracker.
Third parties
We embed only the third-party services strictly required to run the platform. None of them sets advertising or cross-site tracking cookies.
- Supabase — managed Postgres + authentication (EU-hosted, Frankfurt). Sets the auth cookie listed above.
- Vercel — application hosting. Does not set user-facing cookies on NJYN.
No advertising cookies. NJYN does not use Google Analytics, Meta Pixel, LinkedIn Insight Tag, or any other ad-tech tracker. Marketing measurement is opt-in only and currently nothing is active.
Manage your preferences
You can change your choices any time:
- Sign out from inside NJYN to clear the strictly-necessary auth cookie.
- In your browser — every modern browser lets you block or delete cookies. Doing so for the auth cookie will sign you out.
Withdrawing consent does not affect processing that happened before. It also does not delete cookies already set — those expire on their own, or you can clear them in your browser.
Do Not Track & Global Privacy Control
We currently set no analytics or marketing cookies, so Do Not Track and Global Privacy Control signals don't change what NJYN does today. If we ever add non-essential trackers we will respect GPC as a withdrawal of consent for those categories.
Changes
If we add or change a cookie we update this page and the "Last updated" date. Material changes — for example a new third-party tracker — are announced in-product and would require fresh consent.
