Privacy is not a luxury; it's a right. When you write a private note, it should stay private. But most cloud services scan your text for keywords to target ads.
If you write 'pregnant' in a cloud note, expect baby formula ads tomorrow. If you write 'engagement ring', expect jewelry ads.
Notestopin runs entirely in your browser sandbox. Your notes are saved to your hard drive. We don't have a server to receive them even if we wanted to. This architectural decision guarantees that your private thoughts remain truly private.
It's a return to the days when software served the user, not the advertiser.
