It's very rare to actually change things in a liberal democracy with voting. This is a central contradiction of the system, because there is very little incentive for existing governments to offer the ability to vote for policies which would change the status quo. Probably doubly so with something as subversive as what you are suggesting, states don't like it when non-states are able to keep secrets.

Modern labor rights, environmental policy, and basic equality for marginalized groups (women, POC, LGBT people etc.) under the law, are frequently touted as victories of liberal democratic systems but almost all of these rights exist because of massive civil disobedience, and often violent protests.

In all cases, you need huge support of the voter base for a particular issue before voting for a candidate to represent it is ever an option. Even then, there is simply no way to hold elected officials accountable to implementing their platform, and how could there be? No plurality of elected officials would ever want to pass that law in the first place.

This is absolutely not the case in Switzerland where ProtonMail is located. The government doesn't have a say in what questions are voted for. Any proposal that gathers 100k signatures is put to a nation-wide referendum. About a dozen proposals are voted for each year. It is absolutely possible to run a public initiative to change the privacy or criminal laws, provided you have support in the population.

Women's rights actually occurred in defiance of popular numbers by a vote. In the US, the same thing happened for integration of schools.

You do, typically, need a majority of the voters to agree with you. In representative democracy that means you need a plurality of representatives.

Candidates can and do lie. That is something you need to evaluate as part of voting for them.

In defiance of popular numbers, but as a result of decades of (mostly illegal) protests.

It might largely depend on whether you live somewhere with proportional representation or not. Full-on revolution at the ballot box is rare in liberal democracies, sure, but single-issue candidates get elected pretty commonly and often have outsized influence if they're needed for a coalition government.
