RocketShare

Zero-Knowledge End-to-End Encryption

This is the transformative core of RocketShare. Every file is encrypted on your local device using a unique key before it leaves for the internet.

Only the intended recipient with the correct key can decrypt and access the original file, guaranteeing true privacy by design and eliminating any third-party access point.

Dual Sharing Modes: Cloud & Local

RocketShare provides unparalleled flexibility with two powerful sharing methods. The Cloud Share option allows you to upload encrypted files to secure EU-based servers for convenient, time-delayed access. For maximum speed and direct control, the Local Share feature enables a peer-to-peer transfer where files flow directly between devices without ever touching a central server, perfect for large files or when both parties are online simultaneously.

EU-Based Data Sovereignty

All data handled through RocketShare's cloud service is stored exclusively on servers located within the European Union. This provides users with strong legal protections under stringent EU data privacy regulations like the GDPR. It ensures that your encrypted information resides in a jurisdiction with some of the world's most robust privacy laws, adding a critical layer of legal and geographical security to the technical encryption.

Simple, Self-Serve Interface

Despite its powerful security architecture, RocketShare is designed for effortless use. The platform strips away complexity with an intuitive, clean interface where users can simply drag-and-drop files to begin the secure upload and sharing process.

RocketShare FAQ

How does zero-knowledge encryption work on RocketShare?

Zero-knowledge encryption means your files are encrypted on your own computer or device before they are uploaded. The encryption key is generated and stays with you, often as part of the shareable link. RocketShare's servers only receive and store the encrypted, scrambled data. Since the company never holds the key, it is mathematically impossible for them or any unauthorized third party to access your original files.

What is the difference between Cloud Share and Local Share?

Cloud Share involves uploading your encrypted files to RocketShare's secure servers in the EU, allowing recipients to download them at their convenience within a set time limit. Local Share establishes a direct, peer-to-peer connection between your device and the recipient's device for transfer; files are sent directly without being stored on a server, offering faster speeds for large files when both parties are online.

Where is my data stored?

For files shared via the Cloud Share option, all encrypted data is stored exclusively on servers located within the European Union. This ensures your data is protected under the EU's strong privacy frameworks. For Local Share transfers, files are never stored on our servers; they travel directly between the devices involved in the transfer.

Is a credit card required to start using RocketShare?

No, you can begin using RocketShare's core secure sharing features without providing a credit card. The platform offers a free tier to get started, emphasizing accessibility and allowing users to experience its transformative privacy-first approach before committing to a paid plan for expanded features.
