Privacy Policy

QiuDisplay · Effective October 6, 2026

QiuDisplay turns an iPad into an extended display for a Mac. It consists of the QiuDisplay iPad app (App Store) and the free QiuDisplay app for Mac (downloaded from this website). Both are made by QiuSpan (“we”). This policy explains what information QiuDisplay handles and where it goes.

Accounts

QiuDisplay does not require or offer a QiuDisplay user account. We do not ask for your name, email address or phone number in the apps.

Data we collect

The QiuDisplay apps do not send any data to us or to any server operated by us or by third parties. They contain no analytics, advertising, tracking or crash-reporting code. We do not sell or share personal data, and we do not track you across apps or websites.

If you have chosen in your device settings to share analytics with app developers, Apple may provide us with aggregated usage statistics and crash reports under Apple's own privacy terms. These do not identify you to us.

Screen, audio and touch

• Screen. The Mac app creates a virtual display and captures its contents to send them to your paired iPad.
• Audio. If you choose to play Mac sound on the iPad, the Mac app captures system audio and sends it to the iPad.
• Touch. Touches on the iPad are sent to your Mac to move the pointer, click and scroll.

All of this is transferred directly between your own Mac and iPad over your local network (Wi-Fi) or a USB cable. It is not uploaded to us, not sent to any cloud service, and not recorded or stored by QiuDisplay. The Mac app only accepts connections from your local network or USB, and a new iPad must be approved on the Mac before it can connect.

Information stored on your devices

• Pairing. When you approve an iPad on your Mac, a random pairing token and a random device identifier are stored on both devices so they can reconnect. You can remove pairings in the Mac app's settings.
• Settings. Display, quality, sound and other preferences are stored locally.
• Diagnostic logs. Logs are kept only on the device. They leave the device only if you choose to copy and send them to us, for example when asking for support.

Purchases

Purchases, subscriptions, free trials, renewals and refunds are processed entirely by Apple through the App Store using StoreKit. We never receive your credit or debit card number, bank details or Apple Account password.

To confirm that your purchase is valid, the iPad app passes Apple's signed transaction record directly to your own Mac over the local connection, and the Mac app verifies Apple's signature offline. This record contains transaction details such as the product, purchase and expiration dates and transaction identifiers — not your name, email address or payment details. It is not sent to us. Apple's handling of purchases is described in Apple's Privacy Policy.

Permissions

• Local Network (iPad and Mac): to find and connect to your Mac on your own network.
• Screen & System Audio Recording (Mac): to show the extended display on your iPad and, if you choose, play Mac sound there.
• Accessibility (Mac, optional): to let the iPad control the Mac by touch.

This website

This website uses no cookies, no analytics and no third-party scripts, fonts or trackers. Like any web server, it records standard access logs (such as IP address, time, requested page and browser type) to keep the service secure and working. These logs are not used to identify you and are kept only for a limited period.

Children

QiuDisplay is a general-audience utility. It does not collect personal information from anyone, including children.

Your choices

Because the apps do not collect personal data, there is nothing for us to access, correct or delete on your behalf. You can remove all local QiuDisplay data by deleting the apps. If you have sent us an email, you can ask us to delete it.

Changes to this policy

If we change how QiuDisplay handles information, we will update this page and the effective date above before the change takes effect.
