Termpolis R is a mobile companion app to the Termpolis Desktop Application. You need to have the Desktop Application installed for this mobile application.
Termpolis Remote is a companion for the Termpolis desktop app. It lets you check on the terminals already running on your computer, read what they have printed, and type into them, from your phone.
It is a viewer and a keyboard. Nothing runs here. The work happens on your desktop, signed in the way it was already signed in, on the machine where your files, your repositories and your tools already are. Close this app and the work carries on without it.
REQUIRES THE TERMPOLIS DESKTOP APP
Termpolis Remote does nothing on its own. You need Termpolis running on a Mac, Windows or Linux computer, with Remote turned on in Settings. Termpolis is free and open source: github.com/codedev-david/termpolis
RELAY ACCESS IS A SUBSCRIPTION
The app is free to install. Your phone reaches your desktop through a relay we run and pay for, and that is what the subscription covers:
Relay access -- $4.99 per month, auto-renewing. New subscribers get the first week free.
The desktop app stays free and open source. There is no free tier here and nothing is held back from subscribers; the relay is the one thing this app does.
Payment is charged to your Apple ID at confirmation of purchase. It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of that. Manage or cancel it in your Apple ID account settings after purchase. Any unused part of a free week is forfeited when you buy a subscription.

PAIRING TAKES ONE SCAN
Your desktop shows a code. You scan it. Both screens then show the same eight words -- if they match, the two devices agreed on a key nothing in between can derive. If they do not match, something is in between, and the right move is to unpair.
ONE PHONE, SEVERAL DESKTOPS
Pair with up to 16 computers -- a work machine, a home one, a Linux box in the corner -- and switch between them from the terminal list. Each pairing has its own key and its own name, so each desktop grants what this phone may do on that desktop alone, and unpairing one leaves the others exactly as they were.
END TO END, NOT JUST IN TRANSIT
Every message between your phone and your desktop is sealed with a key the two of them derived together, using X25519 key agreement and ChaCha20-Poly1305. The relay that carries the traffic sees a room id, a size and a time. It cannot read a single byte of what passes through it, and it keeps nothing.
YOUR DESKTOP DECIDES WHAT THIS PHONE CAN DO
Reading output, starting terminals, typing, closing terminals -- each is granted on the desktop, in Settings, and each is checked again on the desktop for every request. This app can report what it has been allowed. It cannot grant itself anything.
WHAT IT STORES
One encryption key and one pairing record for each desktop you have paired with, in the iOS keychain, on this device only. No transcript, no scrollback, no cache of what your desktop said. Unpairing erases that desktop's key and record, and works whether or not the desktop is reachable.
WHAT IT DOES NOT DO
No account. No sign-in. No analytics, no crash reporting, no advertising identifier, no tracking of any kind. There is no server of ours that your terminal output ever reaches, because there is nowhere for it to go.
CAMERA
Used for one thing: reading the pairing code on your desktop screen. Frames are decoded on the phone and thrown away. If you would rather not, the pairing code can be typed in by hand.

Fixed a previous bug when launching a new terminal to allow an agent chooser and directory option.
