Terms that sit next to each other
- Client and app: the same thing here. "Client" is the word guides use for an app that connects to a server; on Android it is simply an app from the store.
- Link, key, subscription and profile: all four describe the one text address from the bot. "Subscription" stresses that the app downloads the server list from it, "profile" is what the app calls the saved entry.
- VLESS: the protocol the servers speak, not a brand and not an app. A link of this kind is sometimes called a VLESS key.
- APK: the installer file for an Android app. The same app can arrive from the store or as a file.
- Server: one city in the list, here Singapore, Tokyo, Hong Kong, Sydney or Frankfurt.
Where the words get tangled
The word "key" causes the most confusion. In the status bar a small key icon appears when a tunnel is active, and many guides also call the link itself a key. Two different objects, one word. If a page tells you to look for the key, check whether it means the icon or the text from the bot.
"Free VPN for Android" is the second tangle. It can mean a free app, or a free trial of a paid service. Here the app is free and the service has a 10-day trial; after that a plan is paid in the bot with cryptocurrency. The phrase says nothing about what happens to your traffic, so it is worth asking each time which of the two meanings a page has in mind.
Phone brand names are not a different technology
Samsung, Xiaomi, Oppo, Vivo and Realme all ship Android, and the connection permission is part of Android, so an app behaves the same on each. The brand changes the words in the settings. Battery saving may be called optimisation, power management or app launch on different makers, and the same switch sits in a different corner. When a guide says "allow background activity", the label on your phone may read otherwise; search the settings for the app name instead of for the guide's wording.
Words about the network, and what they do not mean
"Encrypted" means the traffic between your phone and the server is unreadable on the way, for example on a warung Wi-Fi shared by thirty phones. It does not mean faster, and a Telkomsel plan with a weak signal stays weak under a tunnel. "Location" in the server list means where the server stands, and no server is in Indonesia, so an Indonesian address is not on offer. The link holds up to 5 devices at once, which is a limit of the subscription, not of the phone.
Who explains this, and where you decide
Canting sells the plan behind the link, so a glossary from us leans toward our own setup; check any term against the Android screen in front of you. Rules for tunnels differ from country to country and from one network to the next, and the duty to follow local law and the terms of a school, office or café network stays with you.
