Quick Summary
Browser-Only Processing
EML Reader processes your email files entirely in your browser. When you drop an .eml file onto the viewer, your browser reads the file and renders it locally. Nothing is uploaded to our servers. We have no way to see your files, your attachments or your email contents.
This applies to everyone who uses the free online viewer, whether you create an account or not. It also applies to the desktop product, which runs on your computer and reads .eml files from your local disk. No internet connection is required to view your files, and nothing about your file contents is sent back to us.
If you have asked your IT team to whitelist this domain, you can verify the above by inspecting network traffic in your browser developer tools while opening a file.
Data Collection
We collect very limited information, and only when you give it to us yourself.
Data Usage
Anything you share with us is used for a small set of clearly defined purposes.
Security
Information you do share with us is protected through several measures.
Cookies
We use cookies to remember your preferences and improve your experience on the site. You can disable cookies in your browser settings at any time. Some features may not work fully if you disable them.
We do not use cookies for cross-site behavioral tracking, retargeting ads or building profiles of you across the web.
Third Parties
We use a small number of third-party services to run the site. These currently include a web analytics provider, a payment processor for the desktop product and a live chat platform. Each of these providers has its own privacy policy, which you can review on their websites.
Our site may occasionally link to third-party websites or products. These sites operate under their own privacy practices. We do not control them and are not responsible for their content or how they handle your data.
We do not sell, trade or transfer your personal information to anyone outside the small set of providers above, and even those providers see only the data they need to do their specific job.
Your Rights
If you live in the European Union, the United Kingdom, California or another jurisdiction with similar data protection laws, you have specific rights over the data we hold about you.
Policy Updates
We update this policy when our practices change, when new laws apply or when we add features that affect how we handle data. The Last Updated date at the top of this page reflects the most recent revision.
We do not send individual notifications when this policy changes. Please check this page from time to time if these details matter to you.
Questions
If you have questions about this policy, want to exercise one of the rights above or want to flag something we have got wrong, get in touch directly.
