What an extension covers
A VPN extension for Chrome sets a proxy inside the browser. Google's developer page for the proxy interface says it lets an extension manage Chrome's proxy settings, and requires a proxy permission in the extension's declaration. The result is that pages opened in Chrome go through the server, and traffic from outside the browser does not.
For a quick job, such as opening a page on a public network, that may be enough. For anything wider, it is not.
What the extension leaves outside
- Other browsers on the same computer, unless you add the add-on there too.
- Desktop apps, including messengers and game launchers.
- System services such as updates and time sync.
- A DNS lookup done outside the browser, depending on how the add-on is built.
- Anything a company or college policy has locked down on a managed browser.
Free does not mean neutral
A Chrome extension may ask for permission to read and alter the data on websites you open. That is a lot of trust for a free add-on. Open the extension's store page, check the publisher, the number of users and recent updates, and read the list of permissions twice. An add-on that asks to read all your sites is able to see more than a tunnel needs.
A simple test
Add the extension, then open a page that shows your address in Chrome and note it. Open the same page in another browser and compare. If Chrome shows the new address and the other browser shows your own, the extension is working as designed, and also showing you its limit.
When the browser is not enough
On a laptop that you use for study, mail, calls and downloads, an app-level client is the better fit. It takes the subscription link from the Telegram bot, covers the whole device, and works with the same ten-day trial. The five locations are Amsterdam, Frankfurt, Singapore, Dubai and London, and one link has no device limit.
There is no extension of our own. The route here is the client route, and the page on PC and Mac shows how it goes.
A note on the college lab
A lab computer or a managed office laptop often forbids add-ons, and the browser may be set by a policy. Do not try to get around that; the machine belongs to someone else and its rules apply. A VPN is permitted in some places and limited in others, and the terms of the services you open can add their own limits.

Questions
Is a Chrome VPN extension enough for a whole laptop?
No. Only browser traffic is covered. Other apps connect as usual unless you use a client that tunnels the whole device.
How can I judge whether a free extension deserves trust?
It depends on the extension. Look at the publisher, the permissions, how recently it updated and whether it has a privacy policy you can read.
Will the extension work in other browsers?
Not automatically. Each browser needs its own add-on, and each one has a separate setting.
Why does my address not change in another app?
Because the extension changes only Chrome's proxy. That is the limit of this kind of add-on.
Can I use the trial link with an extension?
No. The link goes into a client app. The trial is for the whole-device route, not for a browser add-on.
Does it work on a Chromebook?
An extension runs inside Chrome there too, with the same browser-only limit. Many Chromebooks can also run Android apps, which allows a wider tunnel.
