Jumbo is a new iOS app that aims to help you protect your privacy on various apps and services. Currently, this includes: Facebook, Twitter, Google Search, and Alexa but more are planned. With Jumbo, everything runs locally and is only stored on your device.
With Twitter, it deletes old tweets, then privately backs them up, accessible only by you, on your Jumbo app. With Facebook, it will help manage all the privacy settings, and with Google and Alexa, it’ll clean your saved searches and voice recordings.
Right now the app is free but they plan to make premium features in the future to help sustain the development of the app. If you want to take back control of your privacy give Jumbo a look.
