This page explains the cookies and similar technology (like local storage) that arbostar.com uses, what they're for, and how to control them. It's part of our Privacy Policy, which covers how we handle personal data more broadly.
Cookies are small text files a website stores on your device. They let a site remember things between visits or page loads — like whether you're logged in, or which ads led you here. "Similar technology" includes local storage, which works the same way but is stored differently by your browser.
If you're in the EEA, UK, Switzerland, or Quebec: non-essential cookies (analytics and advertising) only load after you actively accept them in our cookie banner. If you reject them or close the banner without choosing, only strictly necessary cookies run.
Everywhere else: non-essential cookies may load by default when you arrive, and you can opt out using the controls below.
In both cases, you can change your mind at any time.
Built from live scans of arbostar.com, arbostar.com/pricing, and the book-a-demo page (run in September 2026 as a UK visitor and as an Ontario visitor, when every tag loads). "First party" means the cookie is set on the arbostar.com domain; "third party" means it's set on the named provider's own domain.

The demo-booking pages show Calendly's scheduler in a frame. Calendly sets these cookies on its own domain and decides itself whether to ask: if you have not accepted cookies on our site, we do not tell Calendly that you did, so Calendly shows its own cookie choice where the law requires one. See Calendly's cookie notice for details.
If you're in the UK, the EEA, or Quebec, Calendly's own consent tool (OneTrust) asks you before it runs any of its analytics cookies — including the Google Analytics and Google Ads rows below — regardless of the choice you made in our banner. Elsewhere, Calendly may run them by default.
Before you make any choice, the scheduler also runs a few security checks that set no cookie at all: a device-fingerprint check (dfp.calendly.com) and Stripe's own anti-fraud script (m.stripe.network) to screen out abusive bookings, Google's reCAPTCHA to block spam submissions, and Google Identity Services (accounts.google.com) to offer a "Sign in with Google" shortcut in the booking form. These run for every visitor, in every region, because Calendly treats them as security measures rather than analytics or advertising — none of them stored a cookie in our tests.

The Gist chat widget loads with the page and sets these cookies straight away, without waiting for you to open the chat. If you're in the EEA, UK, Switzerland or Quebec, it only loads after you accept cookies.
Some of our pages embed YouTube videos. The video player itself isn't loaded until you either accept cookies or press "Play video" on the notice shown in its place. Once you do, YouTube (Google) sets the cookies below in your browser and receives data from the player, handled under Google's own privacy policy.

Set only after you accept cookies, if you're in the EEA, UK, Switzerland, or Quebec; may load by default elsewhere, per the choice explained above.
If you don't accept, or you haven't chosen yet, neither cookie is written: this was confirmed on the live site with a visitor recognised as browsing from the UK, and, separately, with a real Swedish IP address.

The tables above reflect cookies and storage observed in live automated scans of our pages in September 2026, Calendly's own published cookie rules, and each other vendor's own published documentation. They do not capture every cookie a script might set under different conditions (for example, after you interact with chat or complete a booking) — if you spot something not listed here, let us know at info@arbostar.com and we'll add it.
For how we use the data these cookies collect, and your broader rights over your personal data, see our Privacy Policy.
