Why?
Once your data is saved in RunApps.org, it will not be wiped. All sessions or instances share the same storage space. The worst part is, your sessions aren't private nor secure. It is fully open to the public because of unencrypted Remote Desktop connections.
Anyone can easily access your data, files, and information without your consent. This is a major security flaw that puts your sensitive information at risk. If you are using RunApps for any important tasks or storing sensitive data, you should be extremely cautious.
They claim that their "security is our utmost priority"... Since when did your service have all the security requirements here? Here are some images about it (IP Address has been censored as they do not require a password to get in) (Click to enlarge images):
In conclusion, RunApps.org security practices are HORRIBLE and pose a significant risk to your data and privacy. It is advisable to use alternative solutions that prioritize security and protect your information from unauthorized access and to sign-out after use. Lastly, I highly recommend that you do not use this app for serious work, like logging in your Google accounts because it's very unsecure plus, you can see another users' directories and files.
