RocketShare
Zero-Knowledge Encryption
This is the cornerstone of RocketShare's security. Your files are encrypted on your own computer or phone before they are uploaded. The encryption key never leaves your possession, meaning RocketShare's servers only receive and store data that is completely unreadable to them or anyone else. This guarantees that your privacy is absolute, as even the platform itself has "zero knowledge" of your file contents.
Client-Side Encryption
Building on the zero-knowledge model, client-side encryption means the entire encryption process happens locally on your device. You don't have to trust the security of an online server because the file is already locked and protected before it ever touches the internet. This gives you full control and peace of mind from the very first step.
Flexible Sharing Modes
RocketShare offers two main ways to send files to fit different needs. Use "Cloud Share" for convenient, asynchronous sharing where files are stored encrypted on secure EU-based servers for the recipient to download. Or, choose "Local Share" for a fast, peer-to-peer transfer that sends files directly between devices without them being stored online, perfect for very large files or when you need maximum speed.
EU-Based Data Storage
For users concerned with data sovereignty and regulations like GDPR, RocketShare stores all cloud-shared file data on servers located within the European Union. This provides an additional layer of legal and privacy assurance, ensuring your data is housed under some of the world's strictest data protection frameworks.

RocketShare FAQ
How does RocketShare's encryption work?
RocketShare uses a method called zero-knowledge, client-side encryption. When you select a file to share, our application on your device immediately encrypts it using a unique key before it is uploaded. This key is what decrypts the file, and it is never sent to our servers. Often, this key is embedded in the download link you share. This means we only handle encrypted data that we cannot read or access.
What is the difference between Cloud Share and Local Share?
Cloud Share uploads your encrypted file to our secure servers in the EU, generating a link you can send. The recipient can download it anytime. Local Share creates a direct, peer-to-peer connection between your device and the recipient's device for the transfer. The file never passes through our servers, making it faster for large files and keeping it entirely off the cloud.
Is RocketShare really free to use?
Yes, you can start using RocketShare's core secure sharing features without providing a credit card. This allows you to experience the privacy and simplicity of the platform firsthand. We believe in making true security accessible to everyone from the start.
Where are my files stored?
For files shared via Cloud Share, the encrypted data is stored on our secure servers located within the European Union. For Local Share transfers, files are sent directly between devices and are not stored on any server. In both cases, the actual content of your files remains encrypted and inaccessible to anyone without the unique key.
