Most useful for

Pitfalls to watch at work

The extension reads everything you type in the browser, including form fields: decide in your corporate policy whether it is allowed on work computers
Rewriting a sentence changes its legal meaning: in English contracts and claims, accept only spelling fixes
For text in other languages the service offers almost no suggestions; use LanguageTool for that

Billing

Card payment on the website or through app stores. VAT is added for individuals where required.
