Bzap is designed with privacy as a core principle. We collect the minimum data necessary to deliver push notifications to your devices.
The server stores only what is required to route notifications:
Device registration data: Your device's push notification token (assigned by Apple), a device name (e.g., "iPhone"), and a randomly generated webhook secret. This data is needed to deliver notifications via Apple Push Notification service (APNs).
We do NOT store: notification content, message history, personal information, email addresses, names, or any analytics data. Notification messages pass through the server and are immediately forwarded to APNs — they are never written to disk or logged.
The iOS/macOS app stores notification history locally on your device using SwiftData. This history never leaves your device. You can delete it at any time from the app, and you control the retention period (1 week, 1 month, 3 months, or forever).
Your webhook secret is stored in the device's Keychain, protected by the operating system's security model.
When you tap an action button on a notification, the app sends an HTTP request directly from your device to the webhook URL specified by the notification sender. This request does not pass through our server. We have no visibility into these action webhooks or their destinations.
Apple Push Notification service (APNs): We use APNs to deliver notifications. Apple's privacy policy applies to the push delivery infrastructure. We send Apple your device token and notification content; Apple delivers it to your device.
We do not use any analytics SDKs, tracking pixels, advertising networks, or crash reporting services.
You can delete all your data at any time:
1. On-device history: Delete from the Recent Notifications screen in the app.
2. Server data: Rotating your secret (Settings → Webhooks) effectively invalidates all stored device registrations. Uninstalling the app removes the device token from APNs.
If this policy changes, the updated version will be posted here with a new effective date.
