Mailspring takes the privacy of your data seriously. When you connect email accounts to the app, your email credentials are stored securely in your system keychain. Mailspring does not transmit, store or process your mail in the cloud. For more information about how we protect and handle your data, take a look at the Privacy Policy. We've written up a detailed breakdown of the information that Mailspring stores in the cloud, and we allow you to delete it all in compliance with GDPR.

When you set up the app you can also choose to skip "Mailspring ID" setup, which opts you out of our cloud features and prevents your data from being transmitted off your machine entirely.

If you have reason to believe that Mailspring is subject to a security vulnerability or breach, or believe a third-party or unofficial download site is hosting malware under the Mailspring name, please email our team at [email protected] with as much information as you can provide. You can expect a response within a day.
