Line Mixer

01 Introduction & Overview

This Privacy Policy outlines the privacy practices and operational principles governing the Line Mixer mobile application (hereinafter referred to as "the Application", "the App", or "Line Mixer"), developed by DV Siam.

Line Mixer is an offline-first productivity tool engineered to instantly randomize and shuffle lines of text using the unbiased Fisher-Yates shuffle algorithm. We firmly believe that your data, lists, notes, and text belong solely to you. This policy provides clear, unambiguous documentation on how our software respects your privacy.

02 Information We Do NOT Collect

Line Mixer operates with a strict zero-data philosophy. We do not collect, monitor, store, or transmit any user data whatsoever:

• No Personal Information: We do not ask for or collect names, email addresses, phone numbers, ages, or any personally identifiable information (PII).
• No Text Content Logging: The text lines you enter, paste, shuffle, or copy never leave your device and are never sent to any external server.
• No Device Identifiers: We do not access or collect IMEI numbers, IP addresses, MAC addresses, Android Advertising IDs (AAID), or hardware fingerprints.
• No User Accounts: There is no sign-up, login, password manager, or cloud user profile system.

03 Local On-Device Execution

Every line operation—including line splitting, blank line filtering, Unicode normalization, and Fisher-Yates permutation—is computed solely within the local volatile memory (RAM) of your device.

04 Device Permissions & Clipboard Access

Line Mixer is designed to operate safely without requiring sensitive device permissions:

• No Internet Permission: The app does not request or require the android.permission.INTERNET permission. It functions 100% offline.
• No File Storage Access: The app does not request access to read or write files on your internal or external SD card storage.
• Manual Clipboard Interactions: When you explicitly tap the "Paste" button, the app accesses your system clipboard once to insert your text. Similarly, tapping "Copy Result" places the randomized lines into your clipboard. The app never monitors, logs, or reads your clipboard in the background.

05 Third-Party Services & Advertisements

We do not partner with or incorporate any third-party tracking frameworks, data brokers, or advertising networks:

• Zero Advertising SDKs: No Google AdMob, Unity Ads, AppLovin, or IronSource.
• Zero Analytics or Trackers: No Firebase Analytics, Mixpanel, AppsFlyer, or Crashlytics telemetry.
• Zero Remote Servers: No cloud databases, backend APIs, or web servers interact with the app.

06 Children’s Privacy Protection

Line Mixer strictly complies with the Children’s Online Privacy Protection Act (COPPA) and Google Play Families Policy guidelines.

Since Line Mixer does not collect, retain, transmit, or share any personal information from any user, it is rated for all ages (3+) and is completely safe for children.

07 Data Security

Because all text processing is confined strictly to on-device memory without network connections, your text is inherently safeguarded against external network sniffing, data breaches, and server vulnerabilities. You retain 100% control over your data at all times.

08 Policy Modifications

We may update this Privacy Policy from time to time if future offline enhancements require documentation. Any modifications will be posted directly to this landing page with an updated Effective Date.
