Application code

Is my project secure as in I don't have a source code? 



1) No project is entirely secure on the MIT server as with any server anywhere and MIT does not guarantee it.  The Terms of Service indicate that:

THE SITE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR USE FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. MIT does not warrant the Site will operate in an uninterrupted or error-free manner or that the Site is free of viruses or other harmful components. Use of information obtained from or through this Site is at your own risk. Your access to or download of software, information, materials, or data through the Site or any reference sites is at your own discretion and risk and that you will be solely responsible for any damage to your property (including your computer system) or loss of data that results from the download or use of such material or data.

2) We recommend  users download the aia file periodically for their project to their desktops.  The aia file is the App Inventor 2 source code.   How to create and save an aia file is described here along with how to save/share an apk (the compiled app)  

• Packaging & Sharing Apps

3)  You can also save multiple copies of your Project on the MIT server.   Projects > Save project as ...    where you can give the project another name.. MyProject1, and MyProject2.

4) You can also save Projects > Checkpoint.

If you save copies of the above, your project is secure as possible, however, the Terms of Service still apply..

Is that what you wanted to know?
