Nextdoor

Is Nextdoor safe?

For keeping up with your street, mostly yes. Nextdoor checks that members really live in the neighbourhood they join, asks for real names and blocks registered sex offenders in the US, so it has fewer anonymous trolls than most social networks. The trade-off is privacy. The app knows your home address by design, Apple's label says that address and your email are used to track you for advertising, and scammers have learned that a neighbourly tone opens wallets. We score it 52/100.

That puts it just above Reddit (49) and well above Facebook (37), with a cleaner regulatory record than either but weaker privacy than Reddit, where you can stay anonymous.

What does Nextdoor do with your address?

To join, you give your name, email and home address. The October 2026 privacy policy says Nextdoor confirms accounts by checking third-party data and public records, verification codes or your phone's location, and may ask for ID in some cases.

The data then feeds an advertising business. Apple's privacy label lists five kinds of data used to track you across other companies' apps and sites: physical address, email address, user ID, device ID and advertising data. Data linked to you includes precise location, contacts, search history and a category Apple calls sensitive info. Google Play's data safety section adds web browsing history, collected for advertising.

Members in some jurisdictions can opt out of personalised ads. Everyone else cannot. Nextdoor also ignores browser Do Not Track signals.

Scams and neighbourly trust

Nextdoor's verification gives posts a trust that scammers exploit. BuzzFeed News documented the pattern in 2019: "contractors" who took deposits and vanished, a car-sale scheme paid in eBay gift cards that police in Fishers, Indiana, warned about, and an Oakland arrest of a woman who used a nanny's details from Nextdoor to steal her identity. A visible street address also tells a fraudster exactly who needs a roof fixed.

Nextdoor's own numbers are reassuring on tone. Its 2025 transparency report says less than 1% of content was reported as hurtful and less than 0.5% as harmful, and that new verification steps and machine learning have improved how it blocks fraud and account takeovers. Its 2019 Kindness Reminder, which prompts people before they post a hostile reply, cut negative comments by about 20% in tests. These are company figures, not independent audits.

The app has also faced years of complaints that safety and crime posts single out people of colour. Its privacy policy and help pages now point to bias research and anti-racism resources, but moderation still rests heavily on neighbours and volunteer leads.

Security and regulators

Nextdoor runs a private bug bounty on HackerOne, listed in its security.txt file, and Google Play says data is encrypted in transit. We found no reported breach of member data. The privacy policy mentions two-factor authenticationTwo-factor authenticationSigning in with a second proof of identity on top of your password, such as a code from an app, a security key or a passkey.More in the glossary "where appropriate", but we could not find a setting that lets members turn it on.

No regulator has fined or ordered Nextdoor over privacy or consumer protection that we could find. The closest episode came in the Netherlands in 2019, when residents received printed invitation letters signed with neighbours' names and addresses, which some of those neighbours said they never approved. The Dutch data protection authority confirmed complaints but said it could not act against a company not based there.

How to use Nextdoor more safely

1. In your privacy settings, limit how much of your name and address appears on your profile and next to your posts.
2. Post to your own neighbourhood, not to "Anyone", when you mention being away or a new purchase.
3. Do not sync your address book. It uploads friends' details who never signed up.
4. Hire tradespeople only after checking a licence and reviews off the app, and never pay a large deposit up front.
5. For For Sale and Free deals, meet in a public place and refuse gift cards, wire transfers or payment before you see the item.

How we scored it

Privacy (33) is the weakest factor: your home address and email are tracked for ads, and contact uploads reach people who never joined. Scams and harmful content (50) balances real address checks against well-documented local fraud. The regulatory record (86) is the strongest factor, with no fines, though no regulator has examined the app closely.
