Sent the wrong picture altogether? Telegram can help you out. The app allows users to edit photos and even replace them after you have sent it.

Add Nearby People and Group Besides these security enhancements, you can set a self-destruct timer of duration varying from one second to one week. Furthermore, you or the other person cannot forward messages that you receive within the Secret Chat and taking screenshots (or screen recordings) is completely blocked. Currently, the Secret Chat is limited to conversations between only two people and Secret Groups are not supported within Telegram. Another great option in groups or channels is being able to pin messages. Tap a message and choose Pin to keep it at the top of the chat, where everyone can easily reference it. To create one of these, go to Settings or a Chat Info page, click Edit > click the Profile Picture > select Sticker or Emoji.
The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange. Perhaps the most important and the best feature of the Telegram app is its security. It is based on the MTProto protocol that is built upon time-tested algorithms. It enables high-speed, reliable message delivery on weak connections. Users on macOS now have a quick way to generate a custom profile picture – choose any sticker or animated emoji as the focus, and add a colorful gradient background. You can set one for your own profile, or as a group or channel photo – making it easy to create a themed icon for chats without searching for stock photos. On desktop applications, chat folders are displays in the sidebar. In the mobile app, these folders are arranged in tabs that can be easily swiped between.

It takes care of local data storage, network implementation details, and encryption so that you can focus on design and interfaces.
