What we store
- Your account: e-mail address and password (the password is handled by Google Firebase Authentication and we never see it).
- Private details: your full name and date of birth. Only you and NSM moderators can see these. We ask for your date of birth to keep NSM 13+.
- Your profile: username, display name, display picture, status, personal message and “What I'm listening to”. Your contacts can see these.
- Your messages: text, pictures, voice clips, winks and game moves you send, so they can be delivered and shown in your chat history.
- Contacts: who you've added, blocked or grouped.
- Notifications: a device token so your phone can be told about new messages and calls.
Calls
Voice and video calls go directly between devices where possible. When a direct connection isn't possible, they pass through Cloudflare's encrypted relay. Calls are never recorded.
Keeping NSM safe
NSM automatically checks messages for words linked to serious harm or illegal activity (for example child abuse, drug dealing, weapons, threats or fraud). If a message matches, or someone reports it, a copy of that message and the sender's account details are shared with NSM moderators. Moderators may remove messages, suspend accounts and, where the law requires or someone may be at risk, pass information to the police or child-protection bodies. Nothing else in your conversations is read.
Who processes your data
- Google Firebase stores accounts, profiles and messages.
- Cloudflare relays calls when needed and serves this website.
- Expo delivers push notifications to phones.
- Giphy provides GIF search when you use the GIF picker.
- YouTube plays videos when you use Watch Together. YouTube's own privacy policy applies to the video player; NSM only shares which video is playing with the people in that chat.
We don't sell your data and NSM has no ads.
E-mails
We only send news and updates if you ticked “E-mail me NSM news” when signing up. You can change your mind at any time. Account e-mails, such as password resets, are always sent.
How long we keep it
We keep your data while your account exists. Flagged messages are kept as long as needed to deal with the report.
Deleting your account
You can delete your account yourself at any time: on PC use Help ▸ Delete My Account, on your phone tap ⋮ ▸ Delete my account, or use the delete your account page. It happens straight away and removes your profile, display picture, every message you've sent, your contacts and settings, your username and friend code, your login, and your e-mail, full name and date of birth. Messages your friends sent you stay in their chat history. Reports of flagged messages and suspensions are kept until they've been dealt with, so deleting an account can't be used to avoid moderation.
Your rights
You can ask for a copy of your data, ask us to correct or delete it, or object to how it's used. Contact [email protected]. If you're unhappy with our response, you can complain to the Information Commissioner's Office (ico.org.uk).
Children
NSM is for people aged 13 and over. If you believe a child under 13 has an account, contact us and we'll remove it.
