SendSafely Encryption and Gmail Extension

With the SendSafely Chrome Extension, you can send encrypted files and messages directly from Gmail or using our Chrome pop-out menu. It's never been easier for Chrome or Google Mail users to use SendSafely.

SendSafely is an end-to-end encryption platform that eliminates the need for pre-shared encryption keys and passwords. With SendSafely, nobody other than you and the people you send items to can view them...not even us.

- Built on OpenPGP: OpenPGP is the most widely used email encryption standard in the world. It's been in development and use for years, and proves to be the best encryption available today.

- Multi Factor Authentication: We offer an extra layer of security to keep your information secure. When users access items sent using SendSafely, they are prompted for a username and password, along with a unique SMS code.

- No Software for Recipients: With SendSafely, the people you share items with don't need to download or install on anything on their computer. If they have a web browser, they can receive your files.

Terry Saunders (ID: 000000234e4f2df0) Voted 3 ★ - Updated 01/27/2019 This is not free, and is false advertising. After installing the extension and logging in with my google account, I then got sent an email saying I've started a 14 day pro trial, and there is nowhere on the chrome store about this extension being a trial, also, there is nowhere, anywhere on this extension's details does it mention anything about a pro trial and how much it would cost after the 14 days. Other than that I haven't yet had reason to send anything encrypted so I can't really say how it holds up. As quoted by the email I got sent:- "Thanks for signing up with SendSafely, we are happy to have you on board! Your free 14-day trial of our SendSafely Pro plan is now underway." I wasn't informed that this is a trial, and I wasn't given the opportunity to refuse the trial period. I will be removing it from chrome.
