Cookie ledger · Effective September 29, 2026

Nothing is stored for ads until you press Allow, and one link takes it back.

People find this climbing gym photo shoot location through paid ads on Google, Microsoft and Meta. This ledger lists every cookie and browser key the site can use, who sets each one, how long it lives, and what stops working when you say no. Short answer: nothing you need.

Read the privacy notice

A row of quickdraws and coiled ropes hanging on a wooden rail — L.01Everything on the rail is counted and hung in order. So is this list.

C.00 Effective date

This ledger took effect on September 29, 2026 and was last updated that day. It is kept by Brooklynboulders, trading at brooklynboulders.us, the same operator named in the privacy notice. When a row is added, removed or its lifetime changes, the date above changes with it.

Read each row left to right: the clause, what it means in plain words, and why it applies to this site. On a phone each row stacks into its own labelled block.

Categories of storage
Category	What it means	Why it applies here
C.01Strictly necessary	Storage the site needs to do what you asked. It is on without a banner click because without it the thing you asked for breaks.	Two keys: your consent choice, so the banner does not reappear on every page, and the chat token, so an open conversation with the floor desk survives a reload.
C.02Analytics	Counts visits and which pages were read, as totals. Not used to identify you.	We want to know whether crews read the walls page before writing, or skip it. Off until you press Allow.
C.03Advertising	Links a visit to the ad click that produced it, so the platform can report whether the ad worked.	We run paid campaigns on Google Ads, Microsoft Advertising and Meta Ads today. Off until you press Allow.

Every cookie and storage key
Name	Set by and for	Lasts
K.01 · Necessary`site_consent_v2`	This site, in local storage. Records Allow or Decline and when. The only key on the site that persists a choice.	12 months, then the banner asks again
K.02 · NecessaryChat token	This site's support chat, in local storage. A random token that reconnects you to your own thread with the floor desk. Holds no name or message text.	Until you clear site storage; the transcript on our side is kept 18 months
K.03 · Advertising`_gcl_au`	Google Ads. Stores the `gclid` so an inquiry can be counted as a conversion.	90 days
K.04 · Analytics`_ga`, `_ga_*`	Google Analytics. Distinguishes one browser from another for visit totals.	2 years
K.05 · Advertising`_uetsid`, `_uetvid`	Microsoft Advertising, through its UET tag. Stores the `msclkid` link and counts conversions.	`_uetsid` 1 day; `_uetvid` 13 months
K.06 · Advertising`MUID`	Microsoft. A browser identifier used across Microsoft's ad services.	13 months
K.07 · Advertising`_fbp`, `_fbc`	Meta Ads, where a campaign runs there. `_fbc` holds the `fbclid`; `_fbp` identifies the browser.	90 days

K.03 to K.07 are never written while the Consent Mode signals are denied. If your browser shows one of them and you did not press Allow, tell us; that is a fault and we want to see it.

What happens to the identifier
Clause	Plain words	Why
C.04aIt arrives in the address	The platform puts it in the URL. We cannot stop it arriving, and it does nothing by itself.	That is how Google Ads, Microsoft Advertising and Meta Ads build their links.
C.04bIt is stored only after Allow	With consent, the platform's tag saves it in a cookie from the table above and reports the visit.	So a platform can tell us an ad for a bouldering gym film location in NYC brought one real inquiry, or none.
C.04cIt is dropped after Decline	Nothing saves it and nothing sends it on. It sits in the address bar until you leave the page.	Your refusal is the end of it.

Giving, changing and withdrawing consent
Clause	Plain words	Where
C.06aGiving it	A bar sits at the bottom of the screen on your first visit. It does not cover the page. Press Allow or Decline. Ignoring it counts as no.	The bar on any page
C.06bChanging it	Reopen the bar and press the other button. The change applies on the spot, no reload needed.	"Cookie settings" in the footer of every page, or the button at the top of this page
C.06cWithdrawing it	Press Decline. All four signals go back to denied. Cookies already set by the platforms can be cleared in your browser's site settings.	Same footer link
C.06dBrowser signal	A Global Privacy Control signal from your browser is read as Decline without asking.	Your browser or extension

If you decline
Part of the site	What happens	Why
C.07aPages, photos, shoot finder	Still works Every page, the walls rail and the shoot finder work exactly the same.	None of them rely on ad or analytics storage.
C.07bInquiry form and chat	Still works You can ask for a date and talk to the floor desk.	They use only the strictly necessary keys.
C.07cAd measurement	Stops No ad cookie is written and the click is not reported back.	The ad signals stay denied.
C.07dVisit analytics	Stops Your visit is not stored in our totals.	`analytics_storage` stays denied.
