Peace of Mind — Privacy Policy

Chrome Extension for Content Filtering

Effective Date: March 28, 2026

This Privacy Policy describes the data practices of the Peace of Mind browser extension ("the Extension"), developed and published by SNAC AI LLC ("we," "us," or "our"). Peace of Mind is a content filtering extension designed to help users in addiction recovery avoid triggering content online.

The core principle is simple: all content filtering happens locally on your device. We do not collect, transmit, or store any data about your browsing activity.

1. Information We Collect

We collect no personal information. The Extension does not require an account, login, or registration. There is no sign-up process and no user data is ever sent to our servers or any third party.

2. How the Extension Works

The Extension performs content filtering entirely on your device using the following techniques:

  • Domain blocking: A locally-bundled database of blocked domains is checked against the URLs you visit. This database is included in the extension package — no network requests are made to look up domains.
  • Text scanning: Page text is scanned locally for configurable keywords. All keyword matching, text normalization, and fuzzy matching run in your browser. No page text is transmitted anywhere.
  • Image classification: A machine learning model (NSFWJS, ~4.4MB) is bundled with the extension and runs locally using TensorFlow.js. Images are classified on your device. No images or classification results are sent to any server.
  • Network interception: API responses from websites you visit are scanned locally for keywords. This catches content loaded dynamically by single-page applications. All scanning happens in your browser — no network data is transmitted externally.
  • Safe search enforcement: Search engine URLs are modified locally to enable safe search parameters (e.g., adding safe=active to Google searches). No search queries are logged or transmitted.

3. Data Stored on Your Device

The Extension stores the following data locally in your browser using Chrome's built-in storage APIs (chrome.storage.local):

  • Your settings: Toggle states, preferences, and configuration options you choose in the extension popup.
  • Custom blocklist: Any domains or pages you manually add to the blocklist.
  • Custom keywords: Any words you add to the keyword filter lists.
  • Pending changes: Time-delayed setting changes (e.g., 3-day unblock waiting periods) and their expiration timestamps.
  • Lockdown state: Active cooldown or social media blackout timestamps.

This data never leaves your browser. It is not synced to any server, not backed up externally, and not accessible to us or anyone else. If you uninstall the Extension, this data is deleted automatically by Chrome.

4. Permissions and Why We Need Them

The Extension requests the following Chrome permissions. Each is required for the extension to function as a content filter:

  • storage: Save your settings, custom blocklist, pending changes, and lockdown state locally in your browser.
  • tabs: Read the URL of the active tab to determine whether it should be blocked, scanned, or whitelisted.
  • declarativeNetRequest: Enforce safe search on search engines and block network requests to known harmful content delivery domains. These rules run at Chrome's network layer before pages load.
  • alarms: Run periodic checks (every 60 seconds) to process time-delayed setting changes, clean up expired lockdowns, and verify that protection rules are intact.
  • downloads: Detect and block downloads of media files or executables from blocked domains.
  • offscreen: Create a non-visible document where the image classification model runs. Chrome's service workers cannot run TensorFlow.js directly — the offscreen document provides the necessary browser APIs.
  • host_permissions (all URLs): Content scripts must run on every page to scan text and images. The Extension is a comprehensive content filter — it cannot function if limited to specific websites.

5. Data We Do Not Collect

To be explicit, the Extension does not:

  • Collect, log, or transmit the URLs you visit
  • Collect, log, or transmit the content of pages you view
  • Collect, log, or transmit images or image classification results
  • Collect, log, or transmit your search queries
  • Collect, log, or transmit text you type into input fields
  • Send any data to our servers or any third-party servers
  • Include any analytics, telemetry, or tracking code
  • Include any advertising or monetization code
  • Use cookies or any browser fingerprinting techniques
  • Communicate with any external server for any reason

The Extension makes zero network requests of its own. It only processes network requests that your browser already makes when you visit websites.

6. Third-Party Services

The Extension does not use any third-party services, SDKs, or APIs. There are no analytics providers, no crash reporting services, no advertising networks, and no external data processors. The only external interaction is with the Chrome Web Store for extension updates, which is handled by Chrome itself.

7. Children's Privacy

The Extension does not collect any personal information from any user, including children. Because no data is collected or transmitted, there is no children's data to protect. The Extension complies with the Children's Online Privacy Protection Act (COPPA) by design — it is impossible for the Extension to collect data from children because it does not collect data from anyone.

8. Data Security

All data processed by the Extension remains on your device and within your browser's sandboxed extension storage. Chrome's extension security model prevents other extensions, websites, and applications from accessing this data. The Extension includes tamper detection that monitors for unauthorized changes to protected settings.

9. Changes to This Privacy Policy

If we make material changes to this Privacy Policy, we will update the "Effective Date" at the top of this page. Because the Extension does not collect user data, we have no way to notify users directly — we encourage you to review this page periodically. Any future versions of the Extension that collect data will require explicit user consent before any data collection begins.

10. Your Rights

Because the Extension does not collect any personal data, there is no personal data to access, correct, delete, or port. If you wish to remove all locally-stored Extension data, you can uninstall the Extension from Chrome — all data is deleted automatically. You can also clear Extension data from chrome://extensions without uninstalling.

11. California Privacy Rights

Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), California residents have the right to know what personal information is collected about them. The Extension does not collect, sell, or share any personal information as defined by CCPA/CPRA. There is no personal information to disclose, delete, or opt out of.
