People Are Saying
Our Go-To Marital Messenger
“A really great, simple relationship app with lots of thoughtful touches. after using free for several months, we went to premium for the ability to access history and to save drafts. This will be our go-to marital messenger for now on”
New Favorite App
“Our new favorite app! Sexting is way more fun now that I’m not afraid I’ll accidentally send something to the wrong person, and now that I don’t also see my parents’ pictures in my list of contacts (mood killer). That’s what I was looking for, but I didn’t even realize at first it also came with prompts! So both quality AND frequency have improved ;)”
Safe Way to Improve Private Communication
“This is a great app for communication between myself and my wife! We love that there is no way to send to the wrong person as you are only connected to one person. The app can also be locked so that it can’t be opened by others or children playing with your phone. Shared photos can also be blurred so that they won’t be opened unexpectedly. This is a great and safe way to improve private communication.”
My Wife & I Use This All the Time
“I appreciate how much you can do with a minimal interference from ads. My wife and I use this all the time… It’s good to send each other all kinds of stuff, including explicit photos for free, and videos if you pay to subscribe. Overall a great app!”
Prefer this App Over Snapchat
“We prefer this app over Snapchat. No chance of sending content to the wrong user, and premium version allows you to keep old conversations”
Wholesome & Spicy Suggestions
“***This app is what they say it is!*** +I’ve provided positive feedback and suggestions which were responded to by a real live person. +Info is kept private and it stays on my and my partner’s phone. No one else is able to join the convo because of a key that syncs our phones/accounts. +They have set/passive wholesome and spicy suggestions to help you stay out of a communication rut. These suggestions are passive in that they are sometimes updated for variety during an app software update.”
About the Security
Let's get technical about how the software keeps your messages safe.
- The Just Between Us uses public & private key RSA encryption. This is the same public key encryption used by banks, SSL/HTTPS on websites, and other places where security is essential.
- When the app is first launched, it checks to see if a private key has been generated. If not, the app generates a private key. The private key stays on the phone — it’s not uploaded to any server. However the public key is saved with your profile on the server and is exchanged with your spouse when you sync. If you delete the app without backing up your key, you won’t be able to decrypt your past messages any more.
- An encrypted copy of the message is stored on the server so that messages can be shared and retrieved when one person is offline, but the private keys are not stored with the message. Nothing un-encrypted is ever transmitted off the device.
- Larger messages (say, large images and videos) are chunked into smaller pieces, encrypted, and stored on the server as blobs. Upon retrieval, the chunks are retrieved, decypted, and stitched back together.
- For authentication we hash passwords and all server communication is done over TLS / HTTPS.
