Privacy Policy

Last Updated: September 28, 2026 • Effective Date: September 28, 2026

This Privacy Policy explains how Yiwu Heluo Network Technology Studio (operating under the international trade names "Holos AI" and "Holos Labs", hereinafter referred to as "we", "us", or "our") collects, uses, processes, stores, and protects your personal data when you use:

  • The Holos Android Application (the "App"), including its floating copilot, smart reply, on-device translation, and multimodal vision modules;
  • The Holos Web Platform accessible at https://holos.ing (including the Web Chat Workbench, download centers, and checkout systems);
  • The cloud synchronization APIs and edge services operating under api.holos.ing; and
  • All related services, features, and content (collectively, the "Services").

OUR PRIVACY COMMITMENT: Holos is engineered with a strict Local-First and Data Minimization philosophy. We prioritize on-device machine learning (such as offline neural translation and private local GGUF models), transient memory execution, and zero retention of inference data. We NEVER sell your personal data, and we NEVER use your private messages, uploaded documents, or conversations to train public artificial intelligence models.

1. Android Sensitive Permissions & Data Access (Google Play Policy Compliance)

Certain core features of the Holos Android App rely on Android system permissions to deliver assistive floating tools, contextual smart replies, and instant translation. In strict compliance with Google Play Developer Program Policies, Google Play User Data Policies, and Accessibility API Guidelines, we detail below the exact scope, purpose, and protections governing these sensitive permissions.

A. Android Accessibility Service API (Strict User-Initiated Interaction)

The Holos App includes an Accessibility Service (SmartReplyAccessibilityService). We strictly adhere to the following principles:

  • Specific Data Accessed: The Accessibility Service accesses only the visible on-screen text displayed within the active foreground window of supported instant messaging applications (specifically WhatsApp, Telegram, and Meta Messenger; it does NOT inspect WeChat screen nodes) or text explicitly highlighted by the user with the selection magnifier;
  • Specific and Limited Purpose: The service is used exclusively to:
    1. Inspect the latest incoming message or active chat context solely to formulate relevant, multi-tone AI reply suggestions; and
    2. Backfill the user's selected reply suggestion directly into the target app's text input field upon user request;
  • User-Initiated & On-Demand Operation Only: The Accessibility Service operates strictly upon active, affirmative user interaction (such as actively tapping the floating bubble, tapping the '⚡︎' Quick Reply shortcut, or dragging the screen magnifier). The App NEVER silently, passively, or continuously monitors, logs, scrapes, or records your screen, keystrokes, or background conversations;
  • Assistive Action Scope (Strictly NO Automated Sending): The service performs assistive text insertion into the input field only. The App strictly refrains from automated UI clicking of "Send", "Submit", or "Dispatch" buttons. The user retains sole and exclusive control to review, edit, and manually send any message;
  • No Excluded or Sensitive Data Harvesting: We do not use the Accessibility API to capture passwords, credit card numbers, biometric data, contact lists, phone logs, or complete chat history archives;
  • No Sale, Advertising, or Data Brokering: Data accessed via the Accessibility Service is never sold, never rented, never transferred to data brokers, and never used for targeted advertising, marketing, or behavioral tracking;
  • No System Abuse: We do not use the Accessibility API to alter system settings without user consent, circumvent Android permission frameworks, or impede user control;
  • Prominent In-App Disclosure & Affirmative Consent: Prior to requesting Accessibility permission, the App presents a prominent, blocking disclosure explaining the exact data accessed, its purpose, and security safeguards. The user must provide explicit affirmative consent (Opt-In). You may revoke this permission at any time in Android Settings > Accessibility.

B. MediaProjection & Screen Capture Permission

  • Specific Data Accessed: A single visual frame/screenshot of the active screen at the moment of invocation;
  • Purpose: Used exclusively for full-screen OCR (Optical Character Recognition) and in-place AR translation overlay when you double-tap the floating ball or trigger screen translation;
  • Ephemeral Processing: Screen capture frames are processed transiently in device memory. Captured frames are NEVER recorded as continuous video streams, never stored on disk, never uploaded for surveillance or advertising, and are deleted immediately once text extraction is complete.

C. Notification Listener Service

  • Specific Data Accessed: Incoming notification text (sender name and message preview) originating from supported instant messaging applications (including WhatsApp, Telegram, Meta Messenger, and WeChat);
  • Purpose: To detect incoming conversations and populate quick reply suggestions via standard Android RemoteInput;
  • Data Minimization: Unrelated system notifications (such as banking alerts, email notifications, or system alerts) are ignored. Notification contents are never permanently logged on remote servers.

D. Microphone & Audio Data

  • Specific Data Accessed: Audio streams captured via the device microphone;
  • Purpose: Speech-to-text voice input within the conversation input capsule;
  • 100% On-Device & Offline: Voice audio is transcribed entirely locally on your device using the offline Whisper Tiny model. Audio streams are NEVER transmitted over the internet, never stored on any remote cloud server, and never used for voice biometric profiling.

E. Camera & Photo / Document Storage

  • Specific Data Accessed: Photos captured via the camera or images and PDF documents explicitly selected by the user from the device file picker;
  • Purpose: Multimodal visual question answering, diagram analysis, and document translation in ASK mode;
  • Ephemeral Transmission: Selected media is converted into temporary Base64 representations and transmitted via encrypted TLS 1.3 to the vision AI endpoint solely for the duration of the inference request. The files are not retained for model training.
