I kept running into this while building web products:
If I want to notify a user about something important, the usual options are email, SMS, or WhatsApp, which all require them to hand over some personal information.
Native push feels much cleaner, but for a web product it s surprisingly annoying to implement well.
That s what led me to build Nudgebox: a user scans a QR code, follows a channel, and the business can send notifications directly to their phone. No email or phone number exchanged.
Put a QR code on your site, receipt or status page. People scan it with the free Nudgebox iPhone app and choose what to hear about. No account, email or phone number. Your backend reaches them with one HTTPS call. No SDK, no device tokens.
