Privacy

What information Tonari handles, and what it doesn’t. Last updated: September 28, 2026

Video

The video of your Mac’s screen and the control traffic are sent directly from your Mac to your iPhone, only within the same network. They don’t pass through the internet or our servers. The video is never saved.

The connection is encrypted with a key your iPhone receives from your Mac when you pair (TLS and DTLS, using the operating system’s built-in features). That key is handed over inside a connection encrypted with the QR code’s temporary key, and it’s kept in the keychains on your Mac and iPhone. Each iPhone also gets its own key, so you can unpair iPhones one at a time on your Mac.

Which devices can connect, and what others nearby can see

  • Only iPhones paired by scanning the QR code shown on your Mac can connect, and only from the same network (the same Wi-Fi or Personal Hotspot). Anyone who sees the QR code can pair, so show it only to the iPhone you want to pair. The QR code works only while “Add iPhone” is open on your Mac and stops working once you close it. When a new iPhone is paired, the Mac menu lets you know. You can unpair iPhones one at a time in Settings > Paired iPhones on your Mac. Besides the temporary key, the QR code contains your Mac’s name, an identifier, its network addresses at the time, and the port. Anyone who sees the QR code can read these as well.
  • While Tonari is accepting connections, your Mac’s computer name and a random identifier for recognizing this Mac are visible to devices on the same network (Bonjour). The identifier is created by Tonari the first time it runs and isn’t related to your Apple Account or your device’s serial number. If this concerns you on shared Wi-Fi, turn off accepting connections, or use Personal Hotspot on your iPhone.
  • The iPhone’s camera is used only while scanning a QR code, and no images are saved.

Information we don’t collect

There are no accounts. We don’t collect your name, email address, usage data, or screen contents. The apps contain no advertising or usage analytics.

Checking for updates

Once a day, the Mac app reads appcast.xml from this site to check whether a new version is available. When it does, the app’s name and version are sent. You can turn this off in Settings in the menu.

This site is hosted on Cloudflare Pages. When you view pages or download files, connection records (such as your IP address) are handled within Cloudflare’s systems. This site doesn’t use analytics or cookies.

Logs on your Mac

To help investigate problems, Tonari keeps activity logs on your Mac (~/Library/Logs/Tonari). Only the 20 most recent files are kept (up to 100 MB in total; long sessions are split into 8 MB files), and the app never sends them anywhere. The iPhone app keeps similar logs on your iPhone, up to the 10 most recent files (up to 60 MB in total). The iPhone logs are not included in iCloud or other backups.

Problem reports

Only when you choose “Report a Problem” in the app are the logs collected into a single file (zip). It contains Tonari’s logs (your Mac’s name, the model of the connected iPhone, network addresses, and connection records), Tonari’s crash reports, your device model and OS version, and Tonari’s settings. No screen images are included.

The file stays on your device until you send it yourself, for example by email. The app never sends it automatically. We use the reports we receive only to investigate and fix problems.

The iPhone app saves the diagnostic information that iOS delivers to apps (MetricKit, such as crash records) on your iPhone so that it can be included in this file.

How permissions are used

  • Screen Recording: Used only to capture the screen Tonari creates (the screen shown on your iPhone).
  • Local Network: Used to connect to your iPhone nearby.
