The apps works great and when I had questions the developer answered right away. Great app and great service!
it works really well with my emails. perfect pranks too :)
This app is working great both on Android and in the Chrome-Browser and makes it very easy to use PGP encryption within Gmail. Setup is done in just a few clicks and it is even possible to import your own private keys and to encrypt attachments. Moreover, the customer support is great and so far all of my requests have been answered within a day. Great work!
Excellent solution for encryption of emails. I'd like to see a functioning version to use on iOS
An exceptional, incredibly cool product. It just--works, no hassles. If you use Thunderbird and install gpg4win and the enigmail extension for that, FlowCrypt on Gmail works with Thunderbird too. Support staff are very helpful, even with the free version, which in itself is very pleasantly surprising. I couldn't recommend this extension more highly as a encryption solution for Gmail.
why it needs too much permission and it can read my browser data and also can change it permission???
I've had some questions and sent an email to the developer, they replied in less than 24h with a detailed and very helpful response. 5 stars from me! PS: please consider translating in Greek, too.
fabulous!!!
Thank you. Awesome app with good old PGP. Still waiting for Google Disk encryption. Go ahead!
The developer is fast to respond, however the app itself is buggy. The settings dialog is not getting opened with Firefox extension. I would highly recommend the Mailvelop as more mature and feature rich option.
