In a world where photos, documents, and videos never stop piling up on our devices, cloud storage apps have become like an invisible “vault of the future” that keeps everything safe; from travel memories to work contracts, from massive project files to backups that save you on disaster day. Rumman website brings you the best cloud storage apps, helping you choose a secure, fast, and cost-effective environment for your data without draining your wallet or compromising your privacy.
What are cloud storage apps?
Cloud storage apps are services that store your files on remote servers instead of keeping them locally, allowing you to access them from any internet-connected device, share them via customizable links (permissions, expiration dates, passwords), sync them automatically when edited, and keep multiple previous versions for restoration whenever you want. Most services also provide encryption during transfer, and some add full end-to-end encryption to ensure that only you can decrypt your files, even the service provider itself cannot access them.

- Microsoft OneDrive
- Google Drive
- Sync.com
