01 Overview
Temporary Email Generator ("the extension," "we," or "our") is a free Chrome extension created by Mubashir Hassan that lets you generate disposable email addresses and read incoming messages without signing up for anything.
We built this extension to reduce the amount of personal data floating around the web, so it would make little sense to collect a lot of it ourselves. This policy describes the limited data the extension works with, almost all of which never leaves your own browser.
The plain-language summary: we don't ask you to register, we don't run analytics or advertising, we don't have servers that receive your data, and we never sell or share your information. Temporary inboxes are powered by third-party email providers, and the sections below explain how that works.
02 What the extension does
When you click Generate New Email, the extension requests a brand-new disposable address from a temporary-email provider and shows you any messages that arrive at it. From the popup you can copy the address, view messages as plain text or rich HTML, download attachments, keep a local history of past addresses, and adjust notification and display settings.
The extension does not send email, and it has no access to your real Gmail, Outlook, or any other personal mailbox.
03 Information we handle
The extension works with a small amount of data needed to do its job. It is stored on your device unless a section below says otherwise.
What the extension handles
- The temporary email addresses it generates for you
- Messages and attachments received at those addresses
- A local history of past addresses (up to the 50 most recent), with their creation time and provider
- Your preferences: theme, chosen provider, notification and sound settings, default view
- Basic local counters, such as how many emails you've generated
- The temporary account credentials and access token used to fetch your messages
What we never collect
- Your name, real email address, or any sign-up details
- Passwords for your real accounts
- Your browsing history or activity on other sites
- Analytics, tracking identifiers, or advertising profiles
- Anything sent to servers owned by the developer
Important: a temporary inbox is, by design, not private from the people you give the address to. Anyone who knows a temporary address can potentially view the messages sent to it while it is active. Please don't use temporary addresses for sensitive, financial, or important accounts.
04 Where your data is stored
The developer operates no servers for this extension and never receives a copy of your data. Everything the extension remembers is kept locally in your browser using Chrome's storage:
- Local storage holds your settings, your email history, and local usage counters. This stays in your browser profile until you clear it or remove the extension.
- Session storage holds the active temporary address, its access token, and a short cache of recent messages. This is temporary and is cleared automatically when your browser session ends, and the extension also clears sessions older than 24 hours.
Because this data is tied to your browser profile, it may sync between your devices only if you have Chrome profile sync enabled — that syncing is handled by Chrome itself, under Google's terms, not by us.
05 Third-party services
To actually create inboxes and render some features, the extension communicates with a few external services. When it does, only the minimum information needed is sent, and each service has its own privacy policy that governs that data.
Temporary email providers — Mail.tm & Mail.gw
Disposable addresses and the messages you receive are provided by Mail.tm and Mail.gw. The extension creates a temporary account with the provider you select and fetches your messages from it. The actual email content lives on the provider's systems, so their handling of that data is governed by their privacy policies. If one provider is unavailable, the extension may automatically use the other so you can still get an address.
QR code rendering — QRServer
If you open the QR code feature, the extension asks QRServer (api.qrserver.com) to draw a QR image of your current temporary address. That means the temporary address is sent to QRServer only when you choose to use this optional feature. It is never used for any of your real information.
We encourage you to review the privacy policies of these providers if you want to understand how they process temporary email data. We don't control these third parties and aren't responsible for their practices.
06 Browser permissions
Chrome asks you to approve a set of permissions when you install the extension. Here is what each one is for and why it's needed:
| Permission | Why the extension needs it |
|---|---|
| Storage | Save your settings, email history, and preferences locally in your browser. |
| Clipboard write | Copy a generated email address to your clipboard when you ask it to. |
| Notifications | Show an optional desktop alert when a new message arrives. You control this in Settings. |
| Alarms | Periodically check the active inbox for new messages in the background. |
| Access to api.mail.tm and api.mail.gw | Create temporary inboxes and fetch your messages and attachments from the email providers. |
The extension requests only these permissions and does not request access to your data on the websites you visit.
07 Data retention & deletion
You stay in control of everything the extension keeps:
- Active inbox data is cleared when you click Clear, when your browser session ends, or automatically after 24 hours.
- Email history is capped at the 50 most recent addresses, and you can erase it anytime with Clear History in the History panel.
- All extension data is removed from your browser when you uninstall the extension.
Messages held by the email providers follow their retention rules; temporary inboxes are generally short-lived by nature.
08 Your choices & controls
- Turn desktop notifications and sound alerts on or off in Settings.
- Choose which email provider to use, or let the extension pick automatically.
- Export your email history or current inbox to a file you keep.
- Clear your history or current inbox at any time.
- Remove the extension to delete everything it stored locally.
09 Security
All communication with the email providers happens over encrypted HTTPS connections. The extension follows Chrome's Manifest V3 security model, runs with a restrictive content-security policy, and sanitizes HTML email content before displaying it to reduce the risk of malicious code running in the message viewer.
No method of storage or transmission is ever completely secure, and temporary email is meant for low-stakes, throwaway use. Please treat it accordingly.
10 Children's privacy
This extension is not directed to children under 13, and we do not knowingly collect personal information from children. Since the extension doesn't collect personal information in the first place, it does not build profiles of any users, including minors.
11 Changes to this policy
We may update this policy as the extension evolves or as legal requirements change. When we do, we'll revise the "Last updated" date at the top of this page. Significant changes may also be noted in the extension's listing. Continuing to use the extension after an update means you accept the revised policy.
