About
Plan B VPN is the access tool for teams of Impeltech LLC and the companies we work with. It is not a public service: there is no sign-up, no country picker and no free plan. Your administrator issues an access code, you enter it once, and the device is set up.
HOW IT WORKS
• Enter the code you were given — the app fetches its settings from our gateway and remembers them.
• Slide the switch to the right to connect and to the left to disconnect — no accidental taps.
• Traffic from the device goes through an encrypted tunnel over TLS 1.3 on port 443. To the network it looks like ordinary HTTPS, so it keeps working where other VPNs are blocked.
• The main screen shows the current ping to the server.
• Settings changed on the server? The app picks them up on its own at the next launch.
WHAT WE DO NOT DO
• We do not record the sites you open, your DNS queries or the contents of your traffic.
• We ask for no name, email, phone number or location, and use no advertising identifiers.
• We sell nothing to anyone and show no ads.
WHAT THE APP SENDS US
The access code, so the gateway knows which profile to issue, and a random identifier created on this device at first launch — it exists only so that one code is not used on several devices at the same time. While the tunnel is up, the gateway sees the device's current IP address and the time of the last handshake; that is held in memory and not written down as history. The app explains all of this on screen before you connect.
ONE CODE — ONE DEVICE
A code works on one device at a time. If it is busy elsewhere, turn the VPN off there and it frees up within a minute.
NEED A CODE?
Write to info@impeltech.us. Without a code the app cannot connect — that is by design.

What's New in Plan B VPN
1.2.2
October 26, 2026
Fixed: the VPN did not connect on iPhone 6s, SE (1st generation), 7, 8 and X and on iPads of the same years — it works now. Faster reconnection after sleep and lower memory use.
