RocketShare

Zero-Knowledge End-to-End Encryption

This is the non-negotiable foundation of RocketShare. Every file is encrypted on your own device using a unique key before it is uploaded. Neither RocketShare's servers nor any intermediary can decrypt your data. This means your confidential documents, media, and intellectual property are fundamentally inaccessible to anyone except you and your intended recipient, making it an essential security standard.

Local Peer-to-Peer (P2P) Sharing

For the utmost in speed and privacy, RocketShare offers a local sharing mode. This feature creates a direct, encrypted connection between devices on the same network, transferring files without them ever being stored on an external server. This is a critical option for sharing extremely large files or when you require complete data sovereignty, ensuring the transfer happens entirely under your control.

Secure EU-Based Cloud Storage

When using cloud sharing, your encrypted files are stored on servers located within the European Union. This provides a vital layer of regulatory and legal protection under strict EU data privacy laws like the GDPR. Choosing a platform with known, secure geographic storage is a necessary consideration for compliance and peace of mind for global users.

Simple, Self-Serve Interface

RocketShare delivers military-grade security without the complexity. The platform is designed for immediate use with an intuitive drag-and-drop interface. There are no complicated setups or IT configurations required. This simplicity is essential, allowing teams and individuals to adopt secure practices instantly, without sacrificing productivity for protection.

Use Cases

Coffset

Personal Carbon Footprint Management

Individuals can use Coffset to manage their carbon footprint effectively. By calculating emissions from daily habits like commuting and energy usage, users can take informed steps to offset their impact through verified projects.

Small Business Sustainability Initiatives

Small business owners can leverage Coffset to incorporate sustainability into their operations. By offsetting emissions from business activities, they can enhance their corporate social responsibility and meet customer expectations for environmental stewardship.

Community Engagement in Environmental Actions

Coffset encourages community involvement by allowing local groups to collaborate on offsetting initiatives. By pooling resources and tracking collective emissions, communities can work together to make a substantial impact on their local environment.

RocketShare

Law firms and legal professionals have a fundamental obligation to protect client confidentiality. RocketShare is essential for securely sending case files, contracts, depositions, and evidence. Its zero-knowledge encryption ensures attorney-client privilege is technically enforced, preventing any possibility of a third-party breach or access, which is a non-negotiable requirement in legal practice.

Healthcare Data Transmission

Healthcare providers and administrators must comply with stringent regulations like HIPAA. Sharing patient records, lab results, or medical imaging requires a platform that guarantees privacy by design. RocketShare's encryption-before-upload model is a critical tool for ensuring protected health information (PHI) remains secure during transfer, mitigating severe compliance and reputational risks.

Creative Asset Delivery

Photographers, videographers, and designers must protect their intellectual property and client work. Sending high-resolution galleries, video edits, or design mockups via insecure links is a significant risk. RocketShare provides a simple yet mandatory solution for delivering final assets or proofs with the assurance that work cannot be intercepted, copied, or accessed by unauthorized parties.

Internal Business Collaboration

Teams working on confidential projects, financial reports, merger details, or proprietary R&D cannot rely on standard cloud storage. RocketShare is a necessary infrastructure for internal collaboration, ensuring that sensitive strategic documents shared between departments or remote team members are protected from internal leaks and external threats at every step.

RocketShare FAQ

How does zero-knowledge encryption work with RocketShare?

Zero-knowledge encryption means your files are encrypted on your device before they leave for our servers. You hold the only decryption key, which is often part of the share link. We never have access to your key or the unencrypted data. Even if our servers were compromised, attackers would only find encrypted, unreadable files, making this model essential for true privacy.

What is the difference between Cloud Share and Local Share?

Cloud Share uploads your encrypted files to our secure EU-based servers, allowing recipients to download them at any time. Local Share (Peer-to-Peer) creates a direct, encrypted connection between your device and the recipient's device on the same network; files are transferred directly without ever being stored on our servers. The latter is a critical option for maximum speed and data sovereignty.

Where is my data stored?

When you use the Cloud Share feature, your encrypted files are stored on servers located within the European Union. This choice is intentional and necessary to provide the strong legal privacy protections afforded by EU jurisdiction and regulations like the GDPR, ensuring a higher standard of data governance.

Is a credit card required to start using RocketShare?

No, a credit card is not required to start using RocketShare. You can begin sharing files securely immediately without entering payment details. This allows you to experience the essential privacy and functionality of the platform as a necessity before committing to any paid plan, should you require one.
