How to delete an uploaded app or disable a link on Diawi?
Apps can be managed through the Dashboard: log in with your account before uploading your app, so it is identified as belonging to your account. Then, open the dashboard and click on the cog near the app's status to disable it.
When disabled, the app can't be seen or installed anymore. It is however possible to re-enable it during a few days.
If you want to delete it right away, just click on the cog again to delete it now. It will then be definitely Gone.
Apps uploaded without an account can't be disabled or deleted, they will expire automatically after the link availability expires.
