Privacy Policy

Email Filer Chrome Extension — Last updated: April 26, 2026

Overview

Email Filer is a Chrome extension that lets you save highlighted text snippets from Gmail and organise them into folders, backed by your own Google Drive. This policy explains exactly what data is collected, where it is stored, and what is never collected.

What data we collect

• Text snippets you explicitly save. When you highlight text in a Gmail email and save it, that text and the Gmail URL it came from are stored. Nothing is captured automatically or in the background.
• Folder names you create. The names of any project folders you create inside the extension are stored.

Where data is stored

• Locally on your device using Chrome's chrome.storage.local API, as a local cache for fast access.
• Your Google Drive (required). The extension requires a Google Drive connection to function. Your snippets and folder structure are synced to a private folder named "Email Filer" in your own Drive. The extension uses the drive.file OAuth scope, which limits access exclusively to files it creates — it cannot read or modify any other files in your Drive.

What we do not collect

• We do not collect any analytics or usage telemetry.
• We do not read your emails or any Gmail content automatically.
• We do not transmit any data to our own servers. There are no backend servers.
• We do not share any data with third parties.
• We do not store your Google account credentials. Authentication is handled entirely by Chrome's built-in identity API and Google's OAuth flow.

Third-party services

• Google Drive API. Used only when you explicitly connect Drive. Governed by Google's Privacy Policy.
• Google Fonts. The extension loads fonts (Google Sans, Roboto) from fonts.googleapis.com for display purposes. This is a standard Google Fonts request and is subject to Google's Privacy Policy.

Permissions explained

• storage — saves your snippets and folders locally on your device.
• identity — enables the Google OAuth flow to connect Drive; no credentials are stored by the extension.
• alarms — schedules periodic background sync with Google Drive.
• Content script access: mail.google.com — required to inject the sidebar into Gmail pages. Granted via the content_scripts manifest field; the extension does not request broad tab or browsing-history access.
• Host permission: googleapis.com/drive — required to read and write files in your Drive when sync is enabled.

Data deletion

You can delete all locally stored data at any time by removing the extension from Chrome. If you connected Google Drive, you can delete the "Email Filer" folder from your Drive directly to remove all synced data.

Changes to this policy

If this policy changes materially, the "Last updated" date above will be revised. Continued use of the extension after a change constitutes acceptance of the updated policy.
