Chrome Extension

Privacy Policy

Last updated: June 17, 2026

Overview

TmpMailer is a temporary email service that generates disposable email addresses to protect your privacy online. This privacy policy explains how the Chrome Extension handles your data.

What Data We Collect

The TmpMailer Chrome Extension collects and stores the following data locally on your device:

• Generated email addresses — Stored locally in chrome.storage.local so you can access your inbox from the extension popup
• A random device identifier — Generated on first install to authenticate API requests. This is not tied to your identity
• Temporary authentication tokens — Used to securely communicate with the TmpMailer API

We do NOT collect: Your name, email address, browsing history, cookies, passwords, or any personal information.

How We Use Data

• Generated emails are used solely to provide the service (receive and display temporary emails)
• The device identifier is used to authenticate API requests and prevent abuse
• No data is sold, shared, or transmitted to third parties

Data Storage & Security

All data is stored locally in your browser using chrome.storage.local. API communications are encrypted via HTTPS. We use industry-standard security practices to protect your data in transit.

Third-Party Services

The extension communicates with the TmpMailer API at tmpmailer.com to generate emails and fetch messages. The API is governed by the same privacy standards.

Data Retention

Generated emails are stored locally until you delete them or clear your extension data. Server-side emails are automatically cleaned after 20 days of inactivity.

Your Rights

You can clear all extension data at any time by right-clicking the extension icon → "Manage Extension" → "Clear Storage". This will remove all locally stored emails and session data.
