We have developed a Private Cloud Storage system on Google infrastructure to securely store your files. Only you, and those you share the files with, can see the pages from the THINKERS Notebook.We created our own private storage system to make it easy for you to share files and allow others to comment on those files using their web browser. There is no need for them to have software on their device or an account on your cloud service.Of course, you can download images and files captured from the THINKERS App to your phone and store them on any cloud storage account you have (i.e. Dropbox, Evernote, Google Drive, iCloud, etc).Your security and the App's performance are important to us.
