Privacy Policy for Focus Cat - AI Focus Tutor

Last Updated: June 20, 2026

Privacy-First Promise: Focus Cat is built with privacy as the foundation[cite: 6]. Your webcam feed is processed locally on your device in real-time and is NEVER recorded, stored, or transmitted anywhere[cite: 6]. We collect ZERO personal data, though we track anonymous usage metrics to improve the extension[cite: 4].

1. Introduction

Focus Cat ("we," "our," or "the extension") is a privacy-first productivity Chrome extension that uses local artificial intelligence to help users maintain focus during work or study sessions[cite: 6]. This Privacy Policy explains our data practices and your privacy rights.

2. Information We DO NOT Collect

Focus Cat is designed with privacy as the core principle[cite: 6]. We explicitly DO NOT collect, store, transmit, or process:

Webcam Recordings: Your camera feed is analyzed in real-time using local AI and immediately discarded[cite: 6]. No frames are saved, recorded, or transmitted[cite: 6].
Screenshots or Images: No visual data from your camera is ever saved to disk or memory beyond the milliseconds needed for AI analysis.
Browsing History: We do not track, monitor, or collect information about websites you visit[cite: 6].
Location Data: No GPS coordinates, IP addresses, or location information[cite: 6].
Device Information: No personal device identifiers, hardware specifications, or personal system information.
Third-Party Data Sharing: We do not sell or share personal data. Anonymous interaction metrics are processed purely to improve user experience[cite: 4].

3. Information We Store Locally

The ONLY data stored by Focus Cat is saved locally in your browser using Chrome's storage API and never leaves your device[cite: 4, 6]:

3.1 Productivity Statistics

Daily Time Counters: Three anonymous numbers representing seconds spent in each state (focused, distracted, away from desk)[cite: 4].

3.2 User Preferences

Detection Mode: Your selected monitoring mode preference (laptop/phone , future aspect for new features)[cite: 4].

3.3 Anonymous Identification

Client ID: A randomly generated unique string stored locally to differentiate separate user sessions across analytics events anonymously[cite: 4].

Important: All local data is stored in your local browser storage (chrome.storage.local)[cite: 4]. This local history data never leaves your computer, is not synchronized across devices, and is not accessible to us or any third party[cite: 6].

4. How the Extension Works

4.1 Local AI Processing

Focus Cat uses TensorFlow.js and Teachable Machine libraries that run entirely in your browser[cite: 1, 6]:

AI models are downloaded once during installation and stored locally[cite: 6]
Your webcam feed is processed frame-by-frame in your browser's memory[cite: 1, 6]
Each frame is analyzed and immediately discarded (within milliseconds)[cite: 1, 6]
Only the AI's classification result (focused/distracted/away) is used, not the image itself[cite: 1, 4]
No frames are sent to external servers or cloud services[cite: 6]

4.2 Webcam Permission

Focus Cat requests webcam permission solely for local AI focus detection[cite: 4, 6]:

The camera activates only when you click "Start Focus Session"[cite: 1]
The video feed is displayed to you as a preview for transparency[cite: 1, 6]
The feed is processed locally using on-device machine learning[cite: 6]
No recording, saving, or transmission of video data occurs[cite: 6]
You can revoke camera permission at any time in Chrome settings[cite: 4, 6]

5. Chrome Permissions Explained

Focus Cat requests minimal permissions[cite: 6]:

5.1 Storage Permission

Purpose: Save your daily productivity statistics and preferences locally[cite: 4, 6]
Data Stored: Anonymous time counters, client identifiers, and user preferences[cite: 4]
Location: Local browser storage only (chrome.storage.local)[cite: 4]

5.2 Camera Permission

Purpose: Enable local AI focus detection[cite: 4, 6]
Usage: Real-time analysis only, no recording or storage[cite: 6]
Control: Only active when you start a focus session[cite: 1]

6. Third-Party Services

Focus Cat uses Google Analytics to help improve feature design and stability.

Google Analytics 4 (GA4): We use the GA4 Measurement Protocol to transmit anonymous interaction telemetry (e.g., when the extension is opened, which tracking modes are used, configuration selections, and the total duration the camera remains active per session)[cite: 4, 6].
No personal data, browser footprints, tracking cookies, or video frames are sent to Google Analytics[cite: 4, 6].
No advertisement networks or personal demographic trackers are integrated[cite: 6].

Telemetry Architecture: Focus Cat contains no backend databases or custom infrastructure. Outbound network communication is limited to secure analytics logging intended to discover bugs and evaluate usage trends[cite: 4, 6].

7. Data Security

Since Focus Cat doesn't collect personal data, traditional data security concerns don't apply[cite: 6]. However:

All code runs locally in the isolated Chrome extension environment[cite: 6]
AI processing happens in a sandboxed iframe for additional security[cite: 1, 6]
Local storage data is protected by Chrome's built-in security mechanisms[cite: 6]
Network behavior is explicitly bound to transmitting telemetry signals securely to Google Analytics[cite: 6].

8. Your Privacy Rights

You have complete control over your data[cite: 6]:

Access: All your status metrics are stored locally in chrome.storage.local, accessible only to you[cite: 4, 6]
Delete: Uninstalling the extension removes all stored data[cite: 6]
Modify: You can clear your statistics at any time by reinstalling the extension[cite: 6]
Revoke Permissions: Disable camera access in Chrome settings at any time[cite: 4, 6]

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time[cite: 6]. Any changes will be posted on this page with an updated "Last Updated" date[cite: 6]. Since we don't collect contact information, we cannot notify you directly of changes[cite: 6]. We encourage you to review this policy periodically[cite: 6].

10. Consent

By installing and using Focus Cat, you consent to this Privacy Policy[cite: 6]. You can withdraw consent at any time by uninstalling the extension[cite: 6].
