About FAQ Vault
FAQ Vault answers the kind of question people actually type into a search box: how something works, why it works that way, and what the words mean. Every answer is free to read, and there is no account to create.
How the answers are written
We are straightforward about this, because you should be able to judge what you are reading. Answers here are drafted with the help of large language models, then edited, structured and published under our name. A growing number are written by hand from the outset, usually the ones that explain a mechanism or correct a common misunderstanding.
What that means in practice: we take responsibility for what is published here, and we would rather you knew how it was made than guessed. It also means an answer can be wrong in ways a human expert would not be, which is why the section below matters.
What this is not
Nothing here is professional advice. Answers about health, law, money, immigration or safety are general explanations of how something works, not guidance for your situation. Rules differ by country and change over time. For anything that carries a consequence, speak to someone qualified who can look at your specific circumstances.
Found something wrong?
Please tell us. Corrections are the most useful thing anyone sends us, and we would rather fix an answer than defend it. Include the page and what is wrong with it, and we will correct or remove it.

How it is paid for
Advertising, and direct support from readers. Some answers carry a sponsor credit, which pays for the research behind that page.
A sponsor buys their name beside an answer. They do not get a say in what it says, they do not see it before it is published, and we will refuse a sponsorship that arrives with conditions attached. If that ever stops being true, this paragraph will change. More about supporting the vault.
Your data
We keep as little as we can and say exactly what we keep, for how long, and how to have it removed. It is all in the privacy policy, written to be read rather than skimmed past.
