Tethry
Connecting from your phone
Tethry opens right in your phone’s browser — no app to install. Here’s what to use, and the one Safari setting that trips people up.
Chrome
Supported by defaultJust open your Tethry link (or scan the QR code) in Chrome and connect. Nothing to change, nothing to install.
Works the same on Android and iPhone.
Safari
Turn off Private Relay firstSafari hides your IP by default, which stops the secure connection from forming. One quick setting fixes it:
- Open Settings
- Tap your name at the top → iCloud
- Tap Private Relay → turn it Off
- Reopen your Tethry link in Safari
No Private Relay option? Turn off Limit IP Address Tracking: on Wi-Fi go to Settings → Wi-Fi and tap the ⓘ by your network; on cellular go to Settings → Cellular → Cellular Data Options → Limit IP Address Tracking → Off.
Why this happens
Tethry uses WebRTC — the same peer-to-peer technology behind video calls — to stream your desktop over a direct, end-to-end-encrypted connection. To set that up, the two devices need to discover a network path to each other.
Apple’s iCloud Private Relay and “Hide IP Address” deliberately mask your IP in Safari, which blocks that discovery step — so the connection sits on “connecting” forever. Chrome doesn’t use those features, so it connects out of the box. Turning Private Relay off restores Safari to full speed.
Tethry never sees your screen in the clear either way — the relay only forwards sealed, encrypted packets between your devices.
