This is what you need — ultra-secure free cloud storage.
We believe that cloud storage should be free, just like email. Current cloud storage vendors, like Dropbox, Google, Box, Microsoft and Apple only offer 5-15GB of free storage, which is not enough for your photos and other media files. Now we offer 100GB-1TB of totally FREE online space to everyone, which is big enough for everything you have stored on your PCs and mobile devices.
Free doesn't mean that we don’t take responsibility for your files. We know that you care about security and privacy, and that you don't want anyone else being able to read your files. This is why our service is ultra-secure. We are the only company in the market that ensures that only you can access your files. Thanks to our patent protected TruPrivacy™ technology, all files are encrypted and we don't hold the encryption key. Yes, SurDoc is the first company that can provide full feature service, including cross users’ deduplication, without holding the user's encryption key.
We are also very good at document technology. SurDoc provides the best online document viewer. Upload a complex document to both SurDoc and Google Docs, and you will easily be able to see the difference. This is the power of our patent protected VisiDoc™ technology.
SurDoc works as a huge cloud drive residing in your mobile device or PC. Besides huge free storage, it includes excellent, rich features such as auto-uploading of photos, backing up, accessing, viewing, annotating, signing, and sharing photos, music, movies, documents and more from an unlimited number of devices:

SurDoc – 100GB+ FREE storage APK: questions and answers
Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 2d2af948e3d9c2c3bb609a764b70e903.
