Privacy Policy — Next Block Rewards app
This policy covers the mobile app only. The rewards program and this website are covered separately — see the program and website policy.
What the app collects
- Phone number — to sign you in with a one-time code and to identify your rewards account.
- Account identifier — the account and wallet ID we create for you, sent with each request so we know which wallet to act on.
- Purchase and receipt data — the receipt codes you scan and the purchases they represent, so rewards can be credited and shown in your history.
- Rewards balance and transactions — your balance in satoshis, and the Lightning payments you send and receive.
- Device key and session data — a key generated on your device and held in the device's secure storage, used only to keep you signed in securely.
- Family sharing links — if you use family wallets: which wallets are linked, and transfers between them.
Camera
The app uses the camera only when you choose to scan a receipt code. The scan runs on your device. Images are not stored and are never sent to us — only the code itself is. You can sign in and use the app without granting camera permission.
What the app does not collect
Your name, email address, location, contacts, or advertising identifiers. The app contains no advertising and no third-party analytics SDKs. (This website is separate and does use analytics — see the website policy.)
How we use it
To operate your rewards account, credit and redeem rewards, move funds you ask us to move, prevent fraud, and support you. We do not sell personal data. We do not share it with third parties except service providers that host our systems under contract, or where the law requires it.
Security
Data is encrypted in transit using TLS. Session keys are held in your device's secure storage.
Deleting your account and data
In the app: Settings → Privacy → Delete my data. Or email michael@nextblockcoffee.com with the phone number you signed in with. We complete deletion within 30 days, except records we are required to keep for tax and fraud-prevention purposes.
Full step-by-step instructions, and a breakdown of exactly what is deleted and what is kept, are on the delete your account page.
Children
The app is intended for users aged 18 and over. Family child wallets are created and controlled by a parent account holder.
Changes and contact
We post changes here with a new effective date. Questions: michael@nextblockcoffee.com.
