Cookies.

We use a layered consent system that distinguishes four categories. Strictly necessary technology stays on so the site can remember your choice. Everything else is off until you opt in. You can change or withdraw consent at any time on this page.

// Categories and items

Strictly necessary

Always on

Technically required to operate the site. These items cannot be switched off — without them the page cannot remember whether you have already given consent and basic security headers cannot be applied.

Name	Provider	Purpose	Duration	Legal basis
urban-future-alliance-consent	European Urban Future Alliance (this site)	Stores your cookie preferences so we don't ask you again on every page view.	Up to 12 months in localStorage, then we ask again	Art. 6 (1) (f) GDPR · § 25 (2) Nr. 2 TDDDG (strictly necessary)
sb-<project-ref>-auth-token	Supabase Inc. (EU project hosted on AWS Frankfurt) — set on this domain only	Holds your sign-in session JWT after you authenticate (magic link or OAuth). Without it you would be signed out on every page navigation. Set only after you sign in; never set for anonymous visitors.	Up to 7 days of inactivity, or until you sign out	Art. 6 (1) (b) GDPR (performance of the account contract) · § 25 (2) Nr. 2 TDDDG (strictly necessary for a service explicitly requested by the user)
OAuth round-trip cookie (Google · LinkedIn)	Google LLC / LinkedIn Ireland UC — set on the provider's own domain during the redirect handshake	Required to complete the OAuth round-trip you initiated by clicking 'Sign in with Google' or 'Sign in with LinkedIn'. The cookie is set on the provider's domain (accounts.google.com / linkedin.com), not ours, and is discarded as soon as you land back on this site.	Session only — cleared at the end of the OAuth round-trip	Art. 6 (1) (b) GDPR (performance of the account contract you initiate) · § 25 (2) Nr. 2 TDDDG (strictly necessary for a service explicitly requested by the user — the OAuth sign-in path)

Functional

Off

Improves how the site looks and works. Currently used to load the Inter and JetBrains Mono web fonts from Google so the page renders in its intended typography. With this off, your browser falls back to system fonts.

Name	Provider	Purpose	Duration	Legal basis
Google Fonts (Inter + JetBrains Mono)	Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA	Loads the typeface files from fonts.gstatic.com.

Statistics

Off

Anonymous, aggregated usage measurement so we can see which articles work and which don't. No personal profile is built; the data is used to improve the site.

Name	Provider	Purpose	Duration	Legal basis
Vercel Web Analytics	Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA	Counts page views and referrer sources at an aggregate level.

Server-side aggregates retained for up to 12 months.	Art. 6 (1) (a) GDPR (consent) · transfer to the U.S. covered by the EU-U.S. Data Privacy Framework (Vercel is certified)
Vercel Speed Insights	Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA	Measures page-performance metrics (LCP, CLS, INP, TTFB) so we can spot slow pages. Cookie-free.	No persistent client-side storage.	Art. 6 (1) (a) GDPR (consent) · transfer covered by the EU-U.S. Data Privacy Framework

Marketing

Off

Cross-site advertising and remarketing. We do not run advertising on this site and have no plans to. The category exists so that any future change requires a new, explicit opt-in.

// No items in this category. Reserved for future use.

// Withdrawing consent

You can withdraw consent at any time. Choose Reject all above, or open Customise to flip individual toggles. The change takes effect on the next page load and applies to all of urban-future-alliance.com.
