Who we are
Ang Bao Book (红包簿, “the app”) is made by NJSStudioAI, an independent developer. This policy explains what information the app uses and why. If you have questions, email njsstudioai@gmail.com.
The short version
- There are no accounts. We never ask for your name, email address or phone number.
- Everything you record stays on your phone. We do not run a server, and the app does not send your records to us or to anyone else.
- There are no ads, no advertising ID, and no analytics or tracking tools in the app.
Information stored on your device
The app stores what you enter: people and their relationship, events, guest names, gifts and amounts, dates, birthdays, notes, invitations and settings. This is saved in the app's local storage on your phone only. Deleting the app deletes this data. We cannot see it and cannot recover it for you.
Photos and camera (optional)
If you choose to attach a picture of an envelope, the app asks for access to your camera or photo library. The picture you choose is copied into the app's private storage on your phone. It is not uploaded anywhere. You can use the app without granting this permission.
Face ID, fingerprint and app lock (optional)
If you turn on app lock, the app asks your phone to verify you with Face ID, fingerprint or your device passcode. The check is done by your phone's operating system. The app never receives or stores your biometric data.
Notifications (optional)
Reminders for birthdays, events and backups are scheduled on your phone. No notification data is sent to us.
Backups, export and sharing
You can export a backup file or a spreadsheet (CSV), and import a backup back in. These only happen when you ask. The file is created on your phone and then handed to the share sheet or file picker; nothing leaves your phone unless you pick where to send it. Backup files contain the same information as in the app, so keep them somewhere safe.
Purchases
The app offers a one-time “Pro” unlock. Payment is handled entirely by Apple (App Store) or Google (Google Play). We do not see or store your payment details. The store tells the app whether Pro is unlocked, and the app keeps that status on your phone. See Apple's and Google's privacy policies for how they handle purchase data.
Widgets
Home-screen widgets show a summary from the data already on your phone. They do not send data anywhere.
Children
The app is not directed at children under 13, and we do not collect personal information from anyone.
Data retention and your rights
Because we do not collect or store your data, there is nothing for us to access, correct or delete on our side. You control your data directly: edit or delete it inside the app, or delete the app to remove everything.
Changes
If this policy changes, we will update this page and the date at the top.
