Are you in search of a secure text messaging app with end to end encryption. Well there is no better encrypted secure messaging app than InnerGroup! Now You Can Easily Send & Receive Secure, End-to-End Encrypted Texts, Videos, Pics & Audio! > FREE Download & NO Ads > Perfect for Small & Large Groups > Nothing Stored in the Cloud – Ever! > Stop Worrying About Data Leaks, Spam & Strangers > Ideal for Personal & Professional Use ***About InnerGroup*** With InnerGroup, users start or join a tight-knit group that is comprised exclusively of members – who are called “Groupies”. Only people (a.k.a. Groupies) who are invited can join a group. Everyone else has to request access from the group’s owner. ***Secure Communication*** Groupies send each other secure, end-to-end encrypted texts, videos, picture messages, and audio. There is no cost to send or receive posts, and there is no size limit. **Automatic Router Deletion*** Once a post is delivered to each Groupie, it is automatically and permanently deleted from the InnerGroup router. As such, the only place the post lives is on each Groupie’s device – unless/until they wish to delete it. ***Enhanced Privacy*** InnerGroup doesn’t collect or store any personal information, and there’s no back door. Conversations and posts can’t be tracked, intercepted or monitored. In addition, Groupies don’t have to worry about their contact information or address book being exposed, since they don’t need to provide their email address or phone number to use the app. ***Group Owner Deletion*** If a group’s owner decides to delete a group, then ALL posts are automatically deleted from each Groupie’s device. Group owners can also “prune” their group by removing individual Groupies, and even update their join code to prevent banished Groupies from trying to sneak their way back in! ***Group Lock*** Group owners can also use the handy “Group Lock” feature, which only allows Groupies to comment on posts. If desired, group owners can temporarily disable this feature and allow groupies to create new posts. ***Simple & Easy-to-Use*** InnerGroup’s intuitive design makes starting and joining groups very easy, and sending and receiving posts is as simple, fun and fast as Facebook and other popular social media apps -- but without the security concerns or spam worries. ***Get Started*** InnerGroup is FREE to download and there are NO ads – ever! Once you experience the freedom and security of InnerGroup, you’ll wonder how you ever managed without it!
