Feature Comparison

Caller

Pay-As-You-Go Pricing

With Caller, users benefit from a pay-as-you-go pricing model, starting as low as $0.02 per minute. This feature eliminates monthly fees and hidden charges, allowing users to pay only for the minutes they actually use, making it budget-friendly for all kinds of callers.

Secure and Private Calls

Security is a priority for Caller. All calls and transactions are protected by bank-level encryption, ensuring that conversations remain private and secure. Users can communicate confidently, knowing their data is safe from unauthorized access.

RocketShare

Zero-Knowledge Encryption

This is the cornerstone of RocketShare's security model. Every file you share is encrypted locally on your device before it ever leaves for the internet. The encryption key remains solely with you, typically as part of the shareable link. This ensures that the servers only handle unreadable, encrypted data, making it technically impossible for RocketShare or any third party to access your files' contents. Your privacy is non-negotiable and architecturally guaranteed.

Dual Sharing Modes: Cloud & Local

RocketShare offers unparalleled flexibility with two distinct sharing methods. For convenience and accessibility, use Cloud Share to upload encrypted files to secure EU-based servers, allowing recipients to download at any time. For maximum speed and privacy in real-time collaboration, use Local Share (peer-to-peer), which creates a direct, encrypted connection between devices without the files ever touching an external server, giving you complete control over the data transfer.

EU-Based Data Storage

All data uploaded via the Cloud Share function is stored on servers located within the European Union. This provides users with the strong data protection and privacy regulations afforded by EU jurisdiction, offering an additional layer of legal security and peace of mind for businesses and individuals concerned with data sovereignty and compliance with strict privacy laws like the GDPR.

Private-by-Design Architecture

RocketShare's entire system is engineered from the ground up to protect user privacy. From client-side encryption and zero-knowledge protocols to secure data handling, every technical decision reinforces that your files are for your eyes only. The platform requires no credit card to start, minimizing data collection, and provides transparent resources like a security whitepaper, demonstrating a full commitment to its private-by-design philosophy.

Use Cases

Caller

Remote Team Communication

Caller is an excellent solution for remote teams needing to communicate effectively across different time zones and countries. With no app installation required, team members can connect instantly from their web browsers, facilitating seamless collaboration.

Sales Professionals

Sales teams can leverage Caller to reach potential clients across the globe without worrying about high international calling costs. The pay-as-you-go model allows sales professionals to manage their budgets efficiently while maintaining clear communication with prospects.

Customer Support Services

Businesses providing customer support can utilize Caller to handle calls from international customers. The high-definition audio quality ensures that support representatives can effectively assist customers, enhancing overall satisfaction and service quality.

Family and Friends Communication

Caller also serves personal users looking to stay in touch with family and friends abroad. With affordable rates and easy accessibility from any device, making international calls has never been more convenient for personal communication.

RocketShare

Law firms and legal professionals constantly exchange highly sensitive case files, contracts, and evidence. Using standard email or consumer cloud storage risks attorney-client privilege and compliance breaches. RocketShare allows lawyers to send these documents with the absolute confidence that the content is inaccessible to anyone except the intended recipient, maintaining confidentiality and meeting stringent legal industry standards for data protection.

Secure Client Deliverables for Creatives

Photographers and videographers need to deliver high-resolution galleries and raw footage to clients. These files are large and constitute valuable intellectual property. RocketShare enables fast, secure delivery where only the client with the correct link can access the files. The zero-knowledge model ensures that even RocketShare cannot view the creative work, protecting the artist's IP and the client's privacy throughout the process.

Confidential Healthcare Data Sharing

Healthcare providers, therapists, and research teams need to share patient records, lab results, and study data in compliance with regulations like HIPAA. RocketShare's encryption-before-upload and EU data storage provide a secure channel for this sensitive information, ensuring that patient confidentiality is never compromised and helping organizations maintain critical regulatory compliance during digital transfers.

Internal Business Collaboration

Teams working on confidential projects, financial reports, merger details, or proprietary R&D need a safe space to collaborate. RocketShare's local peer-to-peer sharing allows team members in the same office or on a secure call to transfer files directly between computers at high speed, with no copy ever stored on a cloud server, eliminating the risk of external data leaks during internal collaboration.

RocketShare FAQ

How does zero-knowledge encryption work with RocketShare?

Zero-knowledge encryption means the encryption and decryption of your files happen exclusively on your device. When you upload a file, RocketShare's application on your computer or phone encrypts it first. The resulting encrypted data is then sent to our servers. The key to unlock this data is not stored with us; it is generated and kept by you, often within the share link itself. Since we never have the key, we can never access the original file content.

What is the difference between Cloud Share and Local Share?

Cloud Share involves uploading your encrypted file to RocketShare's secure servers in the EU. The recipient can then download it using the unique link you provide, at any time. Local Share (peer-to-peer) creates a direct, encrypted tunnel between your device and the recipient's device over the internet. The file transfers directly between you without ever being stored on our servers, offering maximum speed and an additional layer of privacy for real-time sharing.

Where is my data stored?

For files shared via the Cloud Share function, all encrypted data is stored on secure servers located within the European Union. This ensures your data is protected under the EU's robust data privacy regulations. For files shared via Local Share (peer-to-peer), the data never touches our servers; it travels directly between the sender's and recipient's devices.

Is RocketShare compliant with regulations like GDPR?

Yes. RocketShare is designed with compliance in mind. By employing a strict zero-knowledge encryption model where we cannot access user data, and by storing all cloud data within the EU, RocketShare helps users maintain compliance with stringent data protection regulations like the GDPR. However, users are always responsible for ensuring their specific use of the tool meets all applicable legal requirements for their industry and jurisdiction.

RocketShare Alternatives

RocketShare is a secure file-sharing platform in the productivity and management category, built on a zero-knowledge encryption model. This means files are encrypted on the user's device before upload, ensuring that no one else, including the service itself, can ever access the content.

These can include budget constraints, the need for specific collaboration features like real-time editing or user management, or a requirement for a different platform or storage location. Some may also seek simpler tools without advanced security or prefer a different pricing structure. When evaluating an alternative, consider your core priorities. Key factors are the level of security and privacy offered, the maximum file size and storage limits, the ease of use for both sender and recipient, and where your data is physically stored and processed. Balancing these elements against your budget will help you find the right fit for your needs.
