Niner is a calling app that rewards you for calling your friends inside Niner. To calculate those rewards, we need to know that a call happened outside Niner. We record when calls start and end, never what was said, who you called outside Niner, or which app you used.
What we collect
- Account: your phone number for sign-in, your name, and an optional profile photo.
- Friends: the Niner user IDs you connect with using a PIN.
- Niner calls: who called whom, whether the call used audio or video, start and end time, and duration.
- Outside-call events on iOS: a call identifier, direction, connection state, and start and end timestamps for calls visible through CallKit while monitoring is on. iOS does not tell us which app placed the call, and we do not try to find out.
- Monitoring coverage: when monitoring was on or off, heartbeat timestamps, and why it stopped.
- Device: platform, model, OS version, and an app-generated device ID.
- Push tokens: so Niner can ring you and send notices.
What we do not collect
Niner does not collect call audio, message content, contacts, location, browsing history, or internet traffic. The background Niner measurement profile that iOS displays as a VPN carries no internet traffic. It only lets Niner detect call events in the background.
Why we use this information
We use it to calculate your Call Share and estimated reward, ring you, show an activity log you can audit, operate the app, and review reports about incorrect entries.
Service providers
We use Google Firebase for sign-in, database, and notifications; Fly.io for call signaling and media relay; and Upstash for presence caching. We do not use advertising networks or data brokers, and we do not sell your data.
How long we keep it
We keep account data while your account exists. Deleting your account from Niner removes your account, friend links, events, and ledger within 30 days. We may retain payout records where required by law.
Your choices
You can pause monitoring, decline notifications, report an incorrect entry, or delete your account. Your reward estimate may change when monitoring is unavailable.
