Some ideas

I would like to see added a feature such it recognizes the key being printed to pdf counted as a backup. In such a case a user might not have wireless access to a printer nor wish to use such. Instead the user might choose to print the key to pdf and encrypt it with a high grade peer reviewed encryption algorithm. Taking this a step further have your app when installed create a local printer to print the key to pdf locally and add the high grade peer reviewed encryption algorithm support for security. Once backup is completed turn off the red dot reminding users to do a backup they already did.

I would also like to be able to create vaults in your app and pick if they are ever auto decrypted and a warning shown if it ever does/try auto decrypts or manually decrypts. Many of us have worked those long hours that when asked questions by an application things are only glanced over and not closely read this will help guard against that. Also a warning should be shown if data is being attempted to be copied to any cloud. It is common news such information is compromised for any number of reasons.

Thank you for a useful application.

Wow - so much control!

Now I can send our proposals that include pricing and other confidential information without worrying about them being shared or used against us! I can just erase them whenever I want. Great product!

Love the app! HOWEVER....

I love what the developers are doing with this app and use it regularly. However, when I’m mobile I use an IPad more than my IPhone so not having an IPad version really limits me from fully integrating it into my business and personal needs. These days, apps like this need to be fully compatible with IPadOS to get serious work done outside of a laptop or desktop.
