Free or paid VPN: what to expect from each
The underlying question
Running servers costs money. If a service is free, somebody covers that cost. Knowing who and how is the only way to judge it.
There are four common models: advertising inside the app, selling browsing data, voluntary donations, or a paid service subsidising the free one.
The first two should give you pause. The last two are sustainable and honest, if declared.
What a paid one usually offers
More servers in more countries, which means less congestion.
Service commitments and support with response times.
Apps for every platform, not just one.
In some cases, external audits of their logging practices. This is the most valuable and the least common.
What a well-run free one can offer
Encryption of the same technical standard: protocols cost nothing, infrastructure does.
No account, which is sometimes a genuine privacy advantage over a paid service that needs your billing details.
Access for people who cannot afford a monthly subscription, which in some countries equals several days of wages.
Warning signs in either kind
It does not explain how it is funded.
It promises total anonymity or undetectable browsing.
It does not say where the company is incorporated or under which jurisdiction it operates.
Its privacy policy is generic and could apply to any product.
It requests permissions it does not need: contacts, precise location, file access.
None of these alone proves bad faith. Several together should stop you.
How to choose
If you need service guarantees, broad coverage and support, pay. That is the sensible answer and there is no way around it.
If you need to encrypt your connection on other people's networks and cannot or will not pay, a transparent free one does that job.
What matters is choosing with information, not slogans. Start with what to check before installing.
