We don't want your data.

The short version

There are no accounts, so there is nothing to sign up for and nothing to log in to. Your screen travels directly from your Mac to your tablet over your own network or a USB connection — it never passes through, and is never stored on, any server we operate. We run no analytics in either app, and this site loads nothing from anyone else.

The Mac host and the tablet app

Wing Display captures your Mac's screen and sends it to your tablet. That connection is made directly between your two devices — on your local network, over your tablet's hotspot, or down a USB cable — and is encrypted in transit using TLS. Screen contents, pointer movement, touches and pen strokes exist only on your Mac and your tablet, for as long as the session lasts. Nothing is written to disk by us, and nothing is transmitted anywhere else.

Neither app contains analytics, telemetry, crash reporting, or advertising of our own. The tablet app includes one piece of Google software: the Google Play Billing Library, which Google requires for anything bought through Google Play. It talks to the Google Play app on your tablet to show prices and to make and check purchases, and it sends Google its own diagnostic information about how that is working, under Google's privacy policy. Apart from it, neither app includes third-party software that collects or sends data: both are built on open-source libraries that run only on your devices, and the Mac host's updater, the open-source Sparkle framework, makes only the version check described below. The latency and statistics readouts some users may have seen are developer tools compiled into internal builds only; they are not present in the apps we ship, and they never transmitted anything in any case.

When you buy Pro, Google Play gives the tablet app a record of the purchase, signed by Google, which includes Google's order number for it. The tablet keeps that record and shows it to your own Mac when they connect, so the Mac can check that it is genuine and turn Pro on — without either device contacting us. The Mac does not store it, and neither app writes it to a log or sends it anywhere else.

The permissions macOS asks for are used only for what they say. Screen recording is what lets us capture the picture to send. Accessibility is what lets your taps and pen become clicks and strokes on the Mac. Local network access is how your tablet finds your Mac without you typing an IP address. We do not use any of them for anything else.

This website

This site sets no cookies and loads no third-party resources. Every file it serves — the stylesheet, the script, the typeface, the images — comes from this domain, so visiting it tells no advertising network, analytics vendor, or content delivery network anything about you. There is no tracking script to block, because there is no tracking script.

The site is served by Cloudflare, our hosting provider, which records requests in its own server logs — including IP addresses — exactly as every web host on the internet does. Those logs belong to the hosting platform and are governed by its policies. We do not receive them, and we do not store them. Cloudflare may also ask your browser to report failed connections back to it, as part of the same hosting service.

Downloads of the Mac host pass through a small Cloudflare program of ours that fetches the file from storage. Cloudflare lets the site's owner watch that program's requests live, as they happen, including their IP addresses. We do not use it to look up visitors, and nothing from it is kept.

What we do see is aggregate: how many requests the site served, how much data it transferred, and how many times the Mac host was downloaded. Those numbers carry no visitor detail. They tell us whether people are finding the product; they cannot tell us anything about you.

Where other companies are involved

The tablet app is distributed through Google Play. Downloading and installing it is a transaction between you and Google, under Google's privacy policy, not ours. So is buying Pro, which happens through Google Play's payment system: Google handles the payment and we never see your payment details. Downloading the Mac host from this site involves no app store and no payment provider — though, as described above, Cloudflare serves the file and records the request in its own logs, exactly as it does for every other page here.

For each Pro purchase, Google Play gives us an order record: Google's order number, the plan and its price, the purchase, renewal and cancellation dates, and the buyer's country — sometimes also region and postcode — plus any reason you choose to give when you cancel. We use it only for accounting, tax and refunds, and it does not include your payment details. Google Play also shows us install counts and, from people who let Google share diagnostics with app developers, crash reports with the device model. Neither app sends any of this to us: it comes from Google Play's developer console, under Google's privacy policy.

Joining the tablet app beta

While the tablet app is in beta, it is available only to testers. You join by asking to join our Google Group, wing-display-beta, either directly or after emailing us. Google hosts the group under its own privacy policy; as its managers we see the name and email address of the Google account you join with, and we use them for one thing: approving you as a tester, which is how Google Play knows to offer you the app. You stay in the group while the beta runs; we remove you when it ends or as soon as you ask, and you can leave it yourself at any time. We never use your address to send you anything else.

Your data rights

We hold no account record, no profile and no usage history. We hold personal data in three cases only, each started by you: if you email us, we have your message and your email address for as long as it takes to answer you; if you join the tablet app beta, the Google account you joined with sits in the beta group described above; and if you buy Pro, we have Google Play's order record for it, described above. You may ask us at any time to show you, correct or delete the first two, and to show you the third, and we will. Order records are kept for as long as accounting and tax rules require.

Wing Display is not directed at children, and neither app collects anything for us from anyone, children included.

Changes and contact

If this policy changes, the date at the top changes with it. Should we ever want to collect something we do not collect today, we will say so here before we start, not after.
