First of all, I would like to apologize for my terrible English, I'm from Brazil.

For those who doesn't know, here in Brazil we are close to our elections for president, and the top runner, called Bolsonaro, promised to "eliminate" the oposition. Crimes are already happening and there are already people dissapearing. And we are really scared.

I would like to ask how safe VPN is. With a free VPN, is there ANY WAY to the military/government can read emails, private mesages or find my location with a VPN in my computer? Is there VPN for smartphones too?

I'm really sorry, I know that all this questions could be really stupid, but I just find out about VPN, and I'm really scared about how things are going here.
