Privacy Policy

1. Scope

This privacy policy applies to the current core functionality of Recept TV, an Android TV app provided by Kaizu Electric Co., Ltd. ("we" / "us"), which operates within an on-site LAN.

2. Information handled

Recept TV stores, on the TV device itself, the reception number, destination, short call text, notification identifier, and timestamp received from a PC, smartphone, or tablet on-site. It also stores display, audio, and public Google Slides URL settings, and an administrative code, on the device.

We do not use in-app advertising, in-app analytics, crash reporting, or user accounts. We do not collect location data, camera footage, microphone audio, contacts, or photos/videos through the app. Cloud Relay traffic occurs only when an operator enables that feature.

3. Purpose of use

Information stored on the device is used for call display, history, re-calling, spoken announcements, idle-screen display, device settings, recovery of the receiving service, and maintenance checks requested by the user.

There is no need to enter names or similar identifying information. We recommend that operators use reception numbers rather than patient or customer names, and send only the minimum information necessary.

4. Communication and third-party services

Recept TV's core communication happens within the same LAN managed by the facility. The current local API uses HTTP rather than HTTPS, so it should only be used on a trusted on-site network and never exposed directly to the internet.

If an administrator enables the public Google Slides display, the TV device accesses the specified Google URL directly. In this case, Google may handle standard web-access information such as IP address and browser/device information in accordance with Google's own terms and privacy policy. We do not have a feature that obtains Google account credentials.

If spoken announcements are enabled, Recept TV passes the call text to a TTS engine installed on the Android device. Whether the TTS engine processes this on-device or communicates with a provider's server depends on the engine used and device settings. Facility operators should check the terms and privacy settings of whichever TTS engine is in use.

When Cloud Relay is enabled, the TV opens a TLS-protected WSS connection to relay.recept.tv. The relay temporarily handles authenticated reception data such as a reception number, destination ID, schedule, and display duration while delivering it to the TV. It may also receive device diagnostics for an authorized management request, including app version, model, receiver state, and overlay-permission state. Relay does not accept patient names, clinical details, the settings code, the TV's LAN address, or port 7979, and it is not the authority for local history or settings. Local LAN operation remains available without Relay.

5. Retention and deletion

The app keeps up to the most recent 100 call records on the device; when a new record exceeds that limit, the oldest record is deleted. Users can delete individual history entries. Clearing the app's data or uninstalling it removes the on-device history and settings. Exported settings do not include history or the administrative code. Relay delivery data is retained only briefly for delivery and status handling, not as a permanent copy of the TV's history or settings. Clearing app data or uninstalling also removes the TV's Relay settings and credentials.

6. Security

Recept TV operates using a combination of the administrative code, Android special-access permissions, the foreground service's notification, and management of the on-site network. Facility operators should properly secure their LAN and Wi-Fi, avoid disclosing the administrative code to unauthorized third parties, and keep the device and app up to date.

7. Our collection and disclosure

We do not sell or share call history for advertising. When Cloud Relay is enabled, authenticated call data and connection/diagnostic data pass through the relay only as needed to deliver the call and answer an authorized management request. If a user voluntarily provides us with logs or screen information for support purposes, we handle it only to the extent necessary to respond to the inquiry. Please remove information that could identify a patient or customer before providing it.

8. Changes to features

Before adding remote device management, accounts, analytics, remote logging, external connectors, or similar features, we will re-evaluate the data flow before release and update this policy and the in-app explanations accordingly. We will obtain consent where required.

9. Analytics on this website

This website (recept.tv) uses Google Analytics 4 to understand traffic and improve its content. Google Analytics may handle pages viewed, referral source, approximate region, device/browser information, and on-page interactions.

On first visit, storage of analytics cookies is denied by default. Analytics cookies are stored only if you choose "Allow." Even when declined, Google's consent mode may still make limited, cookie-less communication. You can change your choice any time from "Analytics settings" at the bottom of each page.

Reception numbers, call content, the administrative code, and on-site LAN settings within the app are never sent to Google Analytics. See Google's Privacy Policy for how Google handles information.
