Privacy Policy

Hear BJB — Last updated: March 2026

Hear BJB is a live audio streaming app for BJB Olomouc church. It delivers real-time interpretation audio to congregation members' phones during services. This policy explains in plain terms what the app does — and importantly, what it does not do — with your data.

What data we collect

None. The app does not collect, store, transmit, or process any personal information about you. Specifically:

• No name, email address, phone number, or any identifier is ever requested or stored.
• No account or registration is required to use the app.
• No location data is accessed or recorded.
• No device identifiers, advertising IDs, or fingerprints are collected.
• No usage analytics, crash reports, or telemetry are sent anywhere.
• The app contains no third-party SDKs for analytics, advertising, or tracking.

Audio stream — not stored, not recorded, not analyzed

The app receives a live audio stream from the church's local server and plays it through your device's speaker or headphones. This audio is the interpretation of the church service, streamed in real time.

The audio data flows exclusively from the server to your device — it is never transmitted back, never stored on any server, never recorded, and never analyzed. The stream exists only in your device's memory for the instant it is being played, and is discarded immediately afterward. No audio file, fragment, or derivative is ever written to disk or sent over the internet.

The church's server produces the audio stream live from a connected sound interface and forwards it to connected listeners. The server does not log who is listening, for how long, or what device they are using.

How Cloudflare is used — and what it does not do

When you are outside the church's local Wi-Fi network, the connection to the server is routed through Cloudflare, a globally trusted internet infrastructure provider. Cloudflare acts strictly as a secure proxy — it creates an encrypted tunnel between your device and the church's server so that the connection remains stable and protected even when accessed remotely.

Cloudflare's role is purely technical and protective:

• It encrypts the connection between your device and the server using TLS (HTTPS).
• It provides a stable, reliable access point regardless of the server's local network conditions.
• It does not inspect, store, or analyze the audio content passing through the tunnel.
• It does not receive, collect, or retain any personal data on our behalf.
• It does not track individual users or build usage profiles.

When you are connected to the church's Wi-Fi, the app connects directly to the local server without using Cloudflare at all — the audio is delivered entirely within the local network, never leaving the building.

Cloudflare may process transient network metadata (such as IP addresses) as part of normal internet routing, subject to Cloudflare's own privacy policy. We have no access to this metadata and do not request or receive it.

Network usage

The app establishes a connection to the church's server to receive the audio stream. No personal data, usage information, or device data is ever sent from your device to the server or to any other party. The only data transmitted is the raw audio stream, flowing one way: from server to your device.

Third-party services

None. The app does not integrate any advertising networks, analytics platforms, social media SDKs, or any other third-party data services. The only external dependency is Cloudflare, used solely as a network tunnel for remote access as described above.

Children's privacy

Because no personal data is collected whatsoever, the app is safe for users of all ages. There are no features that could collect children's data.

Changes to this policy

If the app's data practices ever change, this page will be updated and the date above will be revised. Given the app's deliberately minimal design, significant changes are unlikely.
