Mac DuoPrivacy
The app. Mac Duo reads your display in order to build the glass. Capture runs only while the lid is moving. Nothing is recorded, written to disk, or transmitted. The app does not use analytics, cookies, account tracking, or personal identifiers. The app may connect to macduo.co.uk to check for software updates. Update checks can be disabled from the menu bar.
This website. Payment is handled by Stripe, who receive your email address and payment details directly; we never see your card. We store your email address and what you bought, so that we can send you your download link and tell you about updates. We also count page views, through Vercel Analytics. That measurement sets no cookie, keeps no raw IP address and follows nobody across other sites - it tells us how many people came and which pages they read, and nothing that identifies you. We measure how quickly pages load with Vercel Speed Insights, which also sets no cookie and records nothing that identifies you. When you start a checkout, we pass Stripe a short note of how you arrived: the page you landed on, the name of the site that linked here, any campaign tag in that link, which button you pressed, and whether you are on a phone, tablet or computer. That note is kept in your browser tab, not in a cookie, and is gone when you close it. If you arrive through a creator's link, we also keep that creator's code in a cookie called macduo_ref for 30 days, so that they can be credited if you buy. Only our checkout reads it, and we never send it to Meta. It is separate from the advertising choice below. Creator videos on the homepage are hosted on YouTube. Nothing is requested from YouTube until you press play on one; when you do, it plays through YouTube's privacy-enhanced player, and YouTube receives your IP address and may store information in your browser, under Google's privacy policy.
Advertising measurement, only if you agree. When you visit this website we ask whether we may measure our Facebook and Instagram adverts with the Meta Pixel. If you decline, nothing below happens, and nothing else about the site changes. If you accept, the Pixel loads on the pages of this website other than the download, unsubscribe and admin pages, and tells Meta which page you viewed and when you press the button to start checkout. Meta then receives your IP address, details of your browser and device, and the page address, and sets cookies in your browser (named _fbp, and _fbc if you arrived from a Meta advert). Meta uses this under its own privacy policy, and may use it for its own purposes as well as for ours. If you have accepted when you start checkout, we keep those two cookie values and your browser's description of itself (its user agent; not your IP address) in the note we pass to Stripe, together with a random reference that records your agreement and nothing else about you. Your browser keeps that reference for three days, in cookies called macduo_consent_ref and macduo_consent_ref_set. About 15 minutes after Stripe confirms your payment, our server tells Meta that a purchase took place and the amount you paid, with a one-way hash of your email address and that browser description so that Meta can match it to the advert, unless in the meantime you have declined in the same browser or the payment has been refunded. Nothing from a purchase is sent to Meta if you had declined when you started checkout. You can change your mind at any time with “Tracking choices” at the foot of any page: declining removes Meta's cookies and stops measurement from then on. It cannot recall anything Meta has already received. Your choice is kept in a cookie called macduo_consent_v2 for 180 days, after which we ask again. An earlier version of this question, which did not cover purchases, was kept in a cookie called macduo_consent; that answer no longer counts, so we ask again, and the old cookie is removed when you choose.
Email. We will email you your download link, and we will email you when there is an update to the app you bought. Nothing else. Every email carries an unsubscribe link.
Your rights. Ask us for a copy of what we hold, or ask us to delete it, at hello@studiogohl.co.uk. We will do it within thirty days.
