There seems to be a lot of upheaval at the micro-blogging site. You can either leave the social network or remain and see what happens. It is a good idea to back up your data when an online app is experiencing that kind of behavior. You have to download an archive of your data if you want to use it in the future.
Your archive will include your account info, and history, any apps and devices you used to access it, any accounts you have blocked or muted, all the interests and other ad data that you have listed for you, and your tweets history.
It is very easy to apply for a download of your material in the social network.
You can find your personal icon in the upper left corner of the mobile app. You can choose settings and support for your account. You can use this link if you need to. You can download an archive of your data by clicking on the link. It is possible that you will be asked to verify your account. You can click on the archive.
It can take up to 24 hours before you get the link that will allow you to download your data.
You can either leave your account or keep it. At least you have a record of your time at the social networking site.
