Extension: Drive Photo Classifier

Last updated: June 2026

  Short version: Drive Photo Classifier connects to Google Drive
  to fetch and organise your photos. The AI classification runs entirely inside
  your browser — your photos are never sent to any third-party server. We collect nothing.

1. What This Extension Does

Drive Photo Classifier is a Google Chrome extension that automatically organises photos stored in your Google Drive into labelled folders (Animals, Group Photos, Human, Junk). It connects to Google Drive to fetch and move your photos, while the machine-learning model that classifies them runs entirely inside your browser — photo pixels are never sent to any third-party server.

2. Data We Access

Data	Why	Sent anywhere?
Google Drive file names & metadata	To list and organise your photos	No — stays on your device
Google Drive photo thumbnails	Fed into the AI model for classification	No — processed locally in your browser
Google OAuth token	To call the Google Drive API on your behalf	No — used only to talk to Google's own API

3. Data We Do NOT Collect

We do not upload, store, or transmit any of your photos to any server.
We do not collect analytics, telemetry, or usage statistics.
We do not store your Google account credentials or OAuth tokens beyond your active browser session.
We do not share any data with third parties — there are no third parties involved.
We do not use cookies or any tracking technologies.

4. How the AI Model Works

The photo classification model (EfficientNet-B2, 29.4 MB) is bundled inside the extension package and runs entirely within Chrome's offscreen document using ONNX Runtime WebAssembly. Photo pixels are never sent to any third-party server — classification happens locally in your browser. An internet connection is still required to fetch photos from Google Drive and move them into the organised folders via the Google Drive API.

5. Google API Scopes Used

Scope	Purpose
`https://www.googleapis.com/auth/drive`	Move photos between folders in your Google Drive
`https://www.googleapis.com/auth/drive.file`	Create the organisation folder structure in your Drive
`https://www.googleapis.com/auth/drive.metadata.readonly`	Read file names and MIME types to identify photos

All API calls go directly from your browser to Google's servers using your own OAuth token. No intermediate server is involved.

6. Data Retention

The extension stores only two small items in Chrome's local storage:

Processed file ID list — a list of Drive file IDs that have already been classified, so they are not re-processed on future runs. Stored locally in your browser. Never transmitted anywhere.
OAuth token — managed entirely by Chrome's identity system. We do not persist it ourselves.

You can clear all stored data at any time by uninstalling the extension or clearing Chrome's extension storage.

7. Children's Privacy

This extension is not directed at children under 13. We do not knowingly collect data from children.

8. Changes to This Policy

If we make material changes to this privacy policy, we will update the "Last updated" date above. Continued use of the extension after changes constitutes acceptance of the revised policy.
