RocketShare

Zero-Knowledge End-to-End Encryption

This is the foundational security feature of RocketShare. All files are encrypted on your device using a unique key before they leave your computer. The encryption key is never sent to or stored on RocketShare's servers. Only the person with the correct share link, which contains the key, can decrypt and access the files. This ensures that your data remains completely private, even from RocketShare itself, providing the highest standard of confidentiality for your shared content.

Dual Sharing Modes: Cloud and Local

RocketShare offers flexible sharing methods to suit different security and speed needs. The Cloud Share option uploads encrypted files to secure servers in the EU for easy, accessible sharing. The Local Share (or peer-to-peer) mode creates a direct, encrypted connection between devices for transferring files without them ever being stored on a central server. This is ideal for sharing extremely large files or when you require the utmost control over data transit, as the files move directly from sender to recipient.

Secure EU-Based Data Storage

For files shared via the cloud option, RocketShare ensures all encrypted data is stored on servers located within the European Union. This provides users with the strong data protection guarantees offered by EU privacy regulations, such as the GDPR. Choosing a provider with EU-based storage is a critical consideration for businesses and individuals concerned with jurisdictional data sovereignty and compliance with strict international privacy standards.

Simple, Self-Serve Interface

Despite its powerful security architecture, RocketShare is designed for ease of use. The platform features a clean, intuitive interface where users can simply drag and drop files to begin the secure upload process. There are no complex configurations or IT expertise required. This simplicity ensures that robust, zero-knowledge encryption is accessible to everyone, from solo freelancers to large enterprise teams, without a steep learning curve.

Photographers and videographers can deliver high-resolution client galleries, raw footage, and final edits securely. RocketShare protects their intellectual property from unauthorized access or piracy during transfer. Clients receive a simple link to access their private gallery, ensuring a professional and secure delivery process that safeguards the creative's work and the client's personal moments.

Confidential Business Collaboration

Teams working on confidential projects, such as product development, financial mergers, or strategic plans, require a secure way to share large blueprints, financial models, and internal reports.

RocketShare FAQ

How does zero-knowledge encryption work on RocketShare?

Zero-knowledge encryption means RocketShare has no knowledge of or access to your files or their encryption keys. When you upload a file, it is encrypted on your device using a strong, unique key. This encrypted data is then sent to and stored on RocketShare's servers. The decryption key is not stored with RocketShare; it is typically part of the share link you send to your recipient. Only someone with that full link can decrypt and download the original file. We cannot view, scan, or access your data at any point.

What is the difference between Cloud Share and Local Share?

Cloud Share uploads your encrypted files to RocketShare's secure servers in the EU. This allows recipients to download the files at any time, even if your device is offline. Local Share creates a direct, encrypted peer-to-peer connection between your device and the recipient's device. The file transfers directly without being stored on our servers, which can be faster for very large files and offers an additional layer of control. The local transfer only works while both devices are online and connected.

Where are my files stored?

If you use the Cloud Share feature, your encrypted files are stored on secure servers located within the European Union. We choose EU-based hosting to align with strong data protection regulations. If you use the Local Share (peer-to-peer) feature, your files are never stored on our servers at all; they travel directly between the sender's and recipient's devices during the transfer.

Is a credit card required to start using RocketShare?

No, you can start using RocketShare's core file-sharing services without providing a credit card. The platform offers a free tier or trial to allow users to experience the security and simplicity firsthand. This aligns with our commitment to making powerful privacy tools accessible to everyone from the outset.
