Updated 4 minTry another word, or tell us which question is missing.
No review by licensed professionals has taken place; the legal articles are therefore not advice. Whether a person has approved an article is stated in the “About this article” box below the text.
The person responsible is Hermann Hampel, the founder of Biwak. The texts are created with AI assistance and checked against their sources in a separate pass. Every article names its sources and the date of that check. No review by lawyers or tax advisers has taken place.
No. The legal articles are the groundwork we had to do for ourselves, with the legal references. Where a question depends on your circumstances, the text says so. The decision is up to your adviser or your data protection officer.
Because most AI roll-outs get stuck on these questions, not on the feature list. Anyone who says “your data stays protected” must first have understood which test that sentence has to pass.
Write to kontakt@biwak.ai and tell us which question really comes up in your business. We write about questions that someone actually has.
