Welcome to the community. Projects are associated to e-mail. Do you use the correct one to login in case you have more than one ?

I don't know...did you enter the correct account? Or did you accidentally deleted them?

Hello seo ship

Rest assured that they would not have been deleted from the Server. As dora_peace remarked, ensure you have used the correct email address.

If you still cannot see your projects, let us know which App Inventor Server you are using (for example http://ai2.appinventor.mit.edu).

We can ask MIT to find your projects on the server - but only if we absolutely have to as the team is very busy. So let us know here if you can or cannot see your projects.
