This is what Nextdoor says about privacy:
Fences are sometimes necessary. But online privacy is always necessary. Nextdoor makes it safe to share online the kinds of things you'd be okay sharing with your neighbours in person.
Here's how:
Every neighbour has to verify their address.
Every neighbour signs in with their real name. Just like in person.
Your website is protected by password and encrypted by
HTTPS.
We never share your info with advertisers.
