Thanks for this. Been with Proton a while and they're not great at letting their customers know of new products. Either that or they are too successful at filtering their own marketing email.

To the OP: Proton is privacy first. I use their tools for a reason, trusting file transfer to a third party would never happen even with an open code base.

It's fine if the tool is for yourself, great for your CV and well done for shipping something. HN can at times be a cruel place, think of this as a learning experience.
