Your design must be encrypted before uploading using the app developed by stonefree.design.
The app, although still in the beta version, shortly to be optimised, works perfectly and can be used with the latest operational systems for Mac(OsX) and Windows.
We are in the process of obtaining official approval from Apple Computer for the app. The app does not install any components in the operational system of your computer and is perfectly safe.

FILE NAMING – You must name your design file/folder or the image of your handmade design that you wish to upload onto stonefree.design with a unique code. This code must not be repeated on other designs so that you can always easily identify it within the system. The design code used as the name of the file will automatically be assigned as the design code once uploaded on to the marketplace.
MULTIPLE FILE DESING – If the design is a composition of more than one file, make a zipped folder of the files, name the zipped folder with a unique code (see “file naming” here above) and drag it on to the window in the SFencryptor app.
ATTENTION! Do not modify the name of the encrypted design file or it’s decryption key file.
