PHYSICAL LOCATIONS
Support2U (developers of YOKdata) is located in Lelystad (NL).
Our main servers are located in our DataCenter housed within the AltiCom/Cellnex Media-tower in Lelystad (NL).
From there we have our own fiber connections to the main internet connections in Amsterdam Internet Xchange.
Our storage servers are housed in Alticom/Cellnex Media-towers elsewhere in The Netherlands.
All locations are connected directly through DC-Spine internet connections.

THE WAY IT (BASICALLY) WORKS
After registration and choice of subscription you will be able to store your data on the YOKdata system.
Depending on your choice of subscription you will have the following possibilities available.

Upload file
You need to select a local file on your computer and it will be uploaded to our central server.
After upload has finished, the system will ask you for a personal key to encrypt your uploaded file.
An encryption of your file takes place in the background with a key consisting of a system part and your personal key.
After successful encryption your (encrypted) file will be divided into parts and, with the use of some blockchain technology, these parts will randomly be stored twice on different physical storage locations.
The system does not in any way store the personal key you used for encryption!
The complete process of encrypting, dividing and storing your file will only take a few seconds (depending of the size of the file).

Download file
Once you select a file for download via the web-interface of YOKdata, you will be asked for your personal key. This has to be the same key you have entered when you uploaded the file! Without this personal key or with an uncorrect key, the system will not be able to decrypt your file.
After the system accepted your key, it will recover the various blocks of your file and decrypts your file with the key you entered. The file will then be given available for download only after successfull decryption.

Delete file
Once you select a file for deletion via the web-interface of YOKdata, you will be asked for your personal key. This has to be the same key you have entered when you uploaded the file! Without this personal key or with an uncorrect key, the system will not be able to decrypt your file.
After the system accepted your key, it will delete the various blocks of your file on all the different locations.

Mail file
Once you select a file to mail (max. 10Mb because of email function) via the web-interface of YOKdata, you will be asked for your personal key. This has to be the same key you have entered when you uploaded the file! Without this personal key or with an uncorrect key, the system will not be able to decrypt your file.
After the system accepted your key, it will give you the opportunity to enter the mail address of the recipient and enter a shortmessage.The mail will then be sent with the selected (decrypted)file.

Transfer file
Once you select a file to transfer (max. 10Mb because of email function) via the web-interface of YOKdata, you will be asked for your personal key. This has to be the same key you have entered when you uploaded the file! Without this personal key or with an uncorrect key, the system will not be able to decrypt your file.
After the system accepted your key, it will give you the opportunity to enter the mail address of the person to whom to transfer and enter a shortmessage. The recipient will be sent an email with your message and including a safe link to download the selected file from our servers.

There is of course a lot more to tell about the (technical) details of the above, but that's the part we keep to ourselves.
Sorry!
