Privacy Policy

Your Privacy Matters
to LumiSea

This policy explains what data the LumiSea app (Android & iOS) accesses while controlling and monitoring your fisherman's lamp, and — most importantly — what never leaves your device.

Last updated: August 24, 2026
1. Overview

LumiSea is a mobile app developed by PT. Santinilestari Energi Indonesia for Android and iOS. It lets fishermen connect to, switch on/off, and monitor the battery health of a Lampu Nelayan — a solar‑powered fishing lamp with a built‑in Battery Management System (BMS) — using a direct Bluetooth Low Energy (BLE) connection.

The app talks to your lamp device directly over Bluetooth. It does not require you to create an account, and it does not operate a cloud backend that stores your battery data, your lamp's status, or your identity.

By installing or using LumiSea, you agree to the data practices described in this policy. If you do not agree, please uninstall the app.
2. Data We Collect

LumiSea is designed to work entirely over a direct Bluetooth connection between your phone and your lamp. We — PT. Santinilestari Energi Indonesia — do not operate any server that receives, stores, or processes the data listed below. It stays on your phone and on the lamp device it's paired with.

Account & Identity Data

None. The app has no sign‑up, login, or user profile. We do not collect your name, email address, or phone number.

Bluetooth Device Data

Lamp device name Bluetooth device ID Signal strength (RSSI) during scanning

When you scan for nearby devices, the app reads the advertised name, Bluetooth identifier, and signal strength of lamp devices in range so you can select the one to connect to. This is used only to establish and maintain the Bluetooth connection and is never transmitted off your phone.

Lamp Status & Battery Telemetry (BMS Data)

Lamp on/off status Individual battery cell voltages Battery capacity / state of charge Cell voltage imbalance

Once connected, your lamp's BMS streams live battery and status data to the app over Bluetooth so you can monitor it in the dashboard. This telemetry is displayed in real time and is never uploaded to, routed through, or stored on any server operated by us.

Local App Preferences

The app stores a small set of preferences locally on your device: the last connected lamp (so it can offer to reconnect automatically) and your custom safety warning thresholds (low‑battery and cell‑imbalance limits). This data never leaves your device and is removed when you uninstall the app.

We do not collect analytics, advertising identifiers, contacts, photos, files, or your precise GPS location. See Section 3 for why the app may still request a Location permission on some Android versions.
3. Device Permissions

The table below lists every permission the app can request, on which platform, and exactly what it is used for. You may deny or later revoke most of these in your device Settings; doing so may limit the corresponding feature.

Permission Platform Why it's used
Bluetooth scan & connect AndroidiOS Required to discover nearby lamp devices, connect to the one you choose, send on/off commands, and receive live battery data.
Bluetooth / Bluetooth Admin (legacy) Android ≤ 11 Older Bluetooth permission model required on Android 11 (API 30) and below for the same scanning and connecting described above.
Location Android ≤ 11 An Android OS requirement for classic Bluetooth LE scanning on Android 11 and below — the app does not read, use, or store your GPS location. On Android 12+, the app requests Bluetooth scan permission with the neverForLocation flag specifically so location is not required.
Internet access Android Included by default in the app's underlying web runtime. It is not used to transmit lamp data, battery data, or any personal information to us or to any third party.

We do not request access to your camera, microphone, contacts, call logs, SMS, photo library, or background location.

4. How Your Data Is Used

Everything the app accesses is used for one purpose only: connecting to and operating your Lampu Nelayan device.

  • Device discovery & pairing: Bluetooth scanning finds nearby lamp devices so you can select and connect to yours.
  • Lamp control: Connecting sends on/off commands directly to the lamp over Bluetooth and confirms the lamp's response.
  • Battery monitoring: Live BMS data (cell voltages, capacity, imbalance) is displayed on the dashboard so you can check battery health at a glance, with color‑coded warnings based on your configured thresholds.
  • Convenience & safety: Remembering the last connected lamp and your chosen warning thresholds lets the app reconnect faster and flag low‑battery or cell‑imbalance conditions the way you want.
We do not use any data accessed by this app for advertising, analytics, profiling, or any purpose other than operating and monitoring your lamp. We never sell data — because we never receive it in the first place.
5. Data Sharing

Because LumiSea has no server component and no account system, there is no central place for us to share your data from — we simply never receive it.

  • Between your phone and your lamp: Commands and battery telemetry are exchanged directly, over Bluetooth, with the specific lamp device you connect to — nowhere else.
  • Third parties: We do not share, sell, or transmit any data to advertisers, analytics providers, or other third parties.
  • Legal obligations: As we do not retain any of the data described above, we would have nothing to disclose in response to a legal request; if that ever changes, this policy will be updated accordingly.
6. Data Retention
  • Battery telemetry & lamp status: Never stored anywhere, on either device or any server — it exists only as a live reading for as long as you're connected.
  • Bluetooth scan results: Held in memory only while scanning is in progress; discarded as soon as scanning stops or the app closes.
  • Last connected device & warning thresholds: Retained on your device until you reset them in‑app, clear the app's storage, or uninstall it.
7. Security

The app relies on the lamp's proximity and Bluetooth's pairing model to protect the connection between your phone and your lamp:

  • Proximity‑limited connection: Bluetooth Low Energy only works within a short physical range, so only phones near your lamp can discover or connect to it.
  • Device verification: The app checks that a discovered device exposes the expected lamp Bluetooth service before treating it as a genuine Lampu Nelayan, and disconnects otherwise.
  • No persistent server: With no cloud backend involved, there is no central database of user or battery data that could be breached.
  • Explicit user action required: Scanning, connecting, and sending on/off commands all require an explicit action from you — the app never controls your lamp in the background without your knowledge.
Anyone within Bluetooth range who knows how to pair with your lamp's Bluetooth service could potentially connect to it. Keep physical access to your lamp and phone secure, especially when docked or in port.
8. Your Rights & Choices

Since LumiSea does not create an account or store personal data on any server, there is no remote profile for us to show, correct, or export on your behalf. Your controls are on the device itself:

  • Disconnect anytime: End the Bluetooth connection to your lamp instantly from the in‑app dashboard.
  • Revoke permissions: Disable Bluetooth or Location access at any time from your device's Settings app.
  • Reset or clear local data: Reset your safety thresholds to default in‑app, or clear the app's storage / uninstall it to remove all locally saved preferences, including the remembered last device.

If you have questions about how a specific permission is used, contact us using the details in Section 11.

9. Children's Privacy

LumiSea is a technical utility tool intended for fishermen and boat operators, and is not directed at children.

Since the app collects no personal information and has no account system, it does not knowingly collect data from anyone, including children under 13 (or the applicable minimum age in your jurisdiction). If you believe a child has used the app in a way that concerns you, please contact us at [email protected].
10. Policy Changes

We may revise this Privacy Policy if the app's features or permissions change. When we do, we will:

  • Update the "Last updated" date at the top of this page.
  • Publish the new policy version through the app store listing and/or an in‑app notice ahead of the update that introduces the change, where required by applicable law.

Continued use of the app after a change has been posted constitutes your acceptance of the revised policy. We encourage you to review this page periodically.
