RocketShare
Zero-Knowledge Encryption
This is the cornerstone of your privacy journey. Every file you upload is encrypted locally on your device using a unique key before it is transmitted. This key never leaves your possession, meaning RocketShare's servers only ever handle encrypted, unreadable data. It's a fundamental design that guarantees not even the platform's own engineers can access your files, placing you in complete and absolute control of your data from start to finish.
Local Peer-to-Peer Sharing
For the ultimate in speed and privacy, RocketShare offers a local sharing mode. This feature creates a direct, encrypted connection between your device and the recipient's device, allowing files to travel directly without ever being stored on a central server. It's the digital equivalent of handing over a sealed envelope in person, perfect for sharing extremely large files or when you require the absolute minimum data footprint on the internet.
EU-Based Data Storage
Your encrypted data resides on servers located within the European Union, a region known for its stringent data protection laws like the GDPR. This geographic commitment provides an additional layer of legal and regulatory security, ensuring that data sovereignty is respected and that your information is managed under some of the world's most robust privacy frameworks.
Simple, Self-Serve Interface
RocketShare believes powerful security should not come with a complex setup. The platform is designed with a clean, intuitive drag-and-drop interface. You can start sharing protected files in moments, with no IT department required. This elegant simplicity ensures that everyone, from a solo freelancer to a large team, can embark on their secure sharing journey without any friction or learning curve.

RocketShare FAQ
How does zero-knowledge encryption work?
With RocketShare, encryption happens on your device before upload. You create a share link, which contains or points to the unique decryption key. Your files are scrambled into unreadable ciphertext using this key and then sent to our servers. Since we never receive the key, we cannot decrypt the data. Only someone with the correct link (and key) can unlock and download the original files.
What is the difference between Cloud Share and Local Share?
Cloud Share uploads your encrypted files to RocketShare's secure servers in the EU, allowing recipients to download them at any time, ideal for asynchronous sharing. Local Share establishes a direct, encrypted connection between your device and the recipient's device for the transfer; files are never stored on our servers, offering maximum speed and privacy for immediate, peer-to-peer exchanges.
Can I share files with someone who doesn't have a RocketShare account?
Absolutely. RocketShare is designed for effortless sharing with anyone. You generate a secure link and send it via email, messaging app, or any method you prefer. The recipient simply clicks the link to download the files directly in their browser—no account or software installation is required on their end, making the receiving journey just as simple.
Where are my files stored, and for how long?
All files shared via Cloud Share are stored in their encrypted form on servers located within the European Union. You have full control over the lifespan of your shares. You can set expiration dates for links or manually delete files from the server at any time. Once deleted, the encrypted data is permanently removed from our systems.
