Welcome to WiFi Speaker – PC Audio ("the App"), developed by Jeweality ("we", "our", or "us"). We are strongly committed to respecting and protecting your privacy.

This Privacy Policy explains how our application operates, how it interacts with your local network, and our strict commitment to safeguarding your privacy in full compliance with the Google Play Developer Policies (2026 Edition) and the Google AdMob Publisher Policies.

Unlike many multimedia apps, WiFi Speaker is designed to function without collecting personal information. Specifically:

• No Personal Identifiers: We do not collect names, email addresses, phone numbers, account credentials, or physical addresses. No login or registration is required.
• No Audio Recording or Wiretapping: The app never records, records in background, archives, or uploads any audio samples playing through your speakers.
• No Device Files: We do not access, read, or scan your photos, videos, documents, or file storage.
• No Contacts or Call Logs: The app does not request or access your contact book, call records, or SMS data.
• No Precise Location Data: We do not collect or monitor your GPS coordinates.

WiFi Speaker functions as a high-fidelity, ultra-low latency audio receiver for your computer:

• Windows Companion Server: The user runs a lightweight server script/executable on their Windows computer that captures system audio output (via Windows WASAPI Loopback).
• Local Subnet Transmission: Uncompressed 48 kHz 16-bit PCM stereo audio packets are transmitted directly across your local Wi-Fi router or Mobile Hotspot on port 45454.
• Transient In-Memory Playback: The Android app receives these packets and plays them live through Android's low-latency AudioTrack API. Once played, the samples are instantly discarded from memory (RAM).
• Zero Cloud Relaying: At no point does the audio stream leave your local area network (LAN). The app functions completely even when your Wi-Fi router is disconnected from the internet.

In accordance with Google Play's Limited Permission & Data Minimization guidelines, WiFi Speaker requests only permissions strictly necessary for its advertised core functionality:

To keep WiFi Speaker free of cost, we display advertisements provided by Google AdMob (a service provided by Google LLC).

Data that may be processed by Google AdMob includes:

• Device Identifiers: Google Advertising ID (GAID / AAID), device model, operating system version, and screen size.
• Network & Diagnostics: IP address (used for coarse geographic ad localization and fraud prevention), mobile carrier, and SDK crash logs.
• Ad Interaction Metrics: Information on whether an ad was viewed, clicked, or dismissed.

Google Play & AdMob Policy Adherence (2026):

• No Accidental Clicks: Banner ads are strictly placed at the bottom with a guaranteed 8dp+ safety margin above system navigation bars and buttons.
• No Layout Shifts (CLS): The ad space is reserved prior to loading, preventing content jumps.
• Natural Transition Interstitials: Full-screen interstitial ads are shown only at natural break points (e.g. connecting to a found PC) and are never shown on app launch or exit.
• Frequency Capping: Interstitial ads are limited with a minimum 60-second cooldown timer to prevent ad spam.

You can review how Google handles advertising data by visiting:
Google Privacy Policy  |  Google Advertising Technologies

How to Opt-Out of Personalized Ads:
You can reset or opt out of personalized ads at any time on your Android device by visiting:
Settings → Google → Ads → Delete advertising ID (or "Reset advertising ID").

Audio Stream Retention: Zero retention. Audio frames are received in RAM buffers, decoded, rendered, and freed immediately. No data is written to disk or transmitted to external servers.

App Preferences: The app stores basic operational settings (such as your last connected PC IP address, port number, volume, and latency preset) locally on your device using Android's encrypted DataStore. This data never leaves your device and is completely erased if you uninstall the app or clear its cache in Android Settings.

WiFi Speaker is a general-audience PC utility app and is not directed at children under the age of 13 (or under the age of 16 in the European Economic Area).

We do not knowingly collect, request, or solicit any personal identifiable information from children. If you believe that a child has provided us with personal data, please contact us immediately, and we will take prompt action to investigate and remove any such data.

Under international privacy laws (including the European Union General Data Protection Regulation and the California Consumer Privacy Act), users have specific rights regarding their information:

• Right of Access & Deletion: Because we do not store personal data on remote servers, there is no remote account data to retrieve. All local connection history can be wiped instantly by clearing app data in your phone's Settings.
• Right to Restrict Processing: You may control or limit AdMob personalization via your device's Google advertising settings.
• Non-Discrimination: We do not discriminate against any user for exercising their legal privacy rights.

We may update this Privacy Policy from time to time to reflect changes in our operational practices, application updates, or new Google Play and legal compliance requirements. Any revisions will be published on this page with an updated "Effective Date".
