In this case, it redirects to Google’s general privacy policy that covers all their services. Anyway Google’s calculator stores a history of all the calculations you did in your account somewhere. So I guess it needs to have a policy stating what they do with that data.

Kinda but Thunderbird is community driven, and spun out into an independent subsidiary.

Laura Chambers, who stepped into an interim CEO role at Mozilla in February, says the company is reinvesting in Firefox after letting it languish in recent years,

It’s sort of amusing to me that Mozilla would let the Firefox browser languish. Is that not the raison d’etre of your entire organization? What are you doing with your time and effort if you are allowing your core product to languish? What would people say if Microsoft said “yeah, we’ve allowed windows to languish in recent years.” What an insane notion.

That’s not quite what it means. Legitimate interest is a term from the GDPR, and is one of the legal bases on which a company may process your personal data. Essentially the company has a “legitimate interest” (i.e. reasonable purpose) for which your data must be processed.

Typical examples of legitimate interest are: fraud prevention, direct marketing, or ensuring network/information security of their IT infrastructure.

The rest of your comment is essentially correct though. Notably, the examples above are not exhaustive: legitimate interest is fairly vaguely defined. And there is a process in the GDPR to object to your legitimate interest claim. This has resulted in essentially all data collection companies claiming a generic legitimate interest on your data, and it’s up to you to object to all of them individually. This undermines the general “you must opt in to tracking” principles of the GDPR, but until privacy agencies of the EU get around to some enforcement that’s how it is.

Not exactly, the guy who runs it became a brave employee shortly after starting it. but they claim to continue to run it independently.
