If you were a tsū user and you wanted to download your data archive, tsu has opened for data retrieval. Just log into your account and your data is posted in zip files according to month.
I didn't download my data. I have just about everything I posted. Plus I mainly posted cryptocurrency news along with some of the more personal stuff we share with social networking. Pictures of lunches, places, flowers, etc... Not really worried about that stuff. I lost some email addresses and contacts in my private messages, and even if PM's are included I'm not going through a year and a half of private messages to find a few email addresses. Anyway, if you want your data, it's available for download.
