I have no clue what is being requested. Will try to answer anway.
github allows private repositories. Probably must pay for it.
Google provides some online storage space that can be shared or kept private. It is accessible through a web browser.
To truly keep data accessible and private it should probably be encapsulated in a tar or cpio file, compressed, and then AES encrypted. Without the encryption program and key or pass phrase the encrypted file if downloaded the content can not be viewed/comprehended.
So maybe those 3D designs on google files can be hosted/stored made available to others, perhaps also be encrypted so that those who want to pay for the decryption pass phrase only can access? Maybe?
Good luck.
I had to install a different file browser. This is actually a cleaning app that Google made for phones, but it works great as a file browser, and it's ad free.
After it's installed, at the bottom center of the app, click "Browse"
Scroll to the bottom of the browser page, and click "Internal Storage".
Using the C language linked with the program curl provided library files hosted anywhere on the WWW can be downloaded. The file can be stored AES encrypted. Upon download the program can decrypt the information. Encrypted information on googles servers if stored can not be viewed/comprehended sans encryption key. Probably some encryption libraries exist if not the AES reference source code can be downloaded. The question then becomes how will the program that downloads and decrypts the data display/render it?
Basically, anything remotely stored if private should be encrypted. Through SSL when accessed the data is again encrypted and decrypted when received. Thus on all hops between the unencrypted data can not be attained. To keep google and carnivore out of the data while it is stored on files.google.com the data afore uploading AES encrypt.
Not sure if that was helpful or just repeating what was previously mentioned? As for the extremely obvious answers, a text editor to write source is required, a compiler to compile it might be required, some installed libraries, program make also might be useful. How much skill does Hishammy99 already possess? Might want to decide which programming language to use. I would use C, but that's just my preference.
On iOS, you need to access the files via iTunes?
Yea, I have problem looking for the files on Andriod. I think I might not be using the right app, I'm looking for it using the Files app.
I also have this problem with my p3 64gb. I use the Google File app to periodically look for apps and other files that take up space for no reason. https://files.google.com/
​
I also use the SolidExplorer to look for hidden files that take up space. I honestly haven't ever been able to get it below 25gb of used space though, maybe someone else on here has some tips.
Not sure which edition you have. On my 32Gb X4, I often run quite low on space due to the number of apps I use on the phone.
Based on my use, I am more suitable with 64Gb or even 128Gb.
I'd suggest OP installing Google Files, and use that app to free up some spaces.
