Back to notes

In Japan, data breaches at major companies are reported almost every day. I honestly don’t understand why services store so much information that they don’t actually need.

Sure, collecting detailed information about customers can improve the accuracy of targeted advertising. But is it really worth the cost and risk when that data gets leaked?

Nostr doesn’t even require an email address. It has already proven that you can build useful services without collecting personal information in the first place.
