Caller vs RocketShare

Browser-Based Calling

Say goodbye to app stores and software installations. Caller operates entirely within your web browser, whether you're on Chrome, Safari, or Firefox. This means you can start making high-quality international calls in seconds from any device with an internet connection, without any downloads. It eliminates compatibility issues and frees up storage space on your devices, offering ultimate convenience and flexibility for on-the-go communication.

Transparent Pay-As-You-Go Pricing

Caller champions simplicity and fairness with its straightforward pricing model. There are no monthly subscriptions, contracts, or hidden fees. You simply purchase credits that never expire and only pay for the minutes you actually use on completed calls. With rates starting from just $0.02 per minute to many destinations, you get incredible cost savings and complete control over your communication budget, with real-time usage tracking.

Global Coverage to 200+ Countries

Connect with virtually anyone, anywhere. Caller provides extensive global reach, allowing you to call landlines and mobile phones in over 200 countries and territories worldwide. This extensive coverage ensures that whether you're calling a business partner in London, a relative in Sydney, or a client in Tokyo, you can reach them instantly and reliably, all from one simple platform.

Dedicated Phone Numbers

Enhance your professional image or establish a local presence with your own dedicated phone number. Caller lets you purchase numbers from various countries, including the US and UK, available as local, toll-free, or mobile formats. You can use this number as your caller ID for outgoing calls, giving your business a more established and trustworthy appearance, with activation that happens instantly.

Zero-Knowledge Encryption

This is the cornerstone of RocketShare's security. Your files are encrypted on your own computer or device using a unique key before upload. This encryption key never leaves your control and is never sent to RocketShare's servers. Because the company has "zero knowledge" of your key, it is physically impossible for them to decrypt or view your files. This ensures true privacy, protecting your data from external breaches and internal access alike.

Client-Side Encryption

Building on the zero-knowledge model, encryption happens entirely on your device—this is known as client-side encryption. When you drag and drop a file into RocketShare, the app on your computer immediately scrambles the data into a secure, encrypted format. Only this scrambled, unreadable "blob" is ever transmitted and stored on the remote servers. This means your sensitive information is protected from the very moment you decide to share it.

Secure Share Links with URL Fragments

When you create a shareable link, the decryption key is cleverly embedded within the URL fragment (the part after the #). This fragment is not sent to the server during transmission; it stays locally in the browser of the person you're sharing with. The server only handles the encrypted file data and basic metadata (like file name and expiry), while the crucial key travels directly and securely to the recipient, enabling them to decrypt the file.

Flexible Sharing Modes (Cloud & Local)

RocketShare offers two powerful ways to share. The Cloud Share mode uploads your encrypted file to secure EU-based servers for easy, asynchronous sharing with anyone, anywhere. The Local Share (coming soon) mode creates a direct, peer-to-peer connection between devices for transferring files without them ever touching an external server, ideal for the most sensitive transfers on a local network.

Remote and International Teams

For distributed companies and remote workers, Caller is a game-changer. Team members can easily connect for meetings, quick check-ins, or collaborative discussions with colleagues in different countries without worrying about exorbitant international calling charges on their personal phones. It simplifies communication and keeps global teams tightly knit and productive.

Freelancers and Small Businesses

Freelancers and small business owners who work with international clients can use Caller to maintain professional, cost-effective communication. They can make client calls, conduct interviews, or provide customer support using a dedicated business number, projecting a professional image while keeping overhead costs extremely low with the pay-per-minute model.

Staying Connected with Family and Friends

For individuals with loved ones abroad, Caller offers an affordable and simple way to stay in touch. Instead of relying on expensive carrier plans or less reliable apps, users can enjoy crystal-clear HD voice calls to mobile and landline numbers in their family's home country, making regular conversations easy and budget-friendly.

Business Sales and Support

Sales and customer support teams can leverage Caller to reach customers and prospects globally. The service allows for high-volume calling to international numbers at a fraction of the cost of traditional business phone systems. The dedicated number feature also helps build local trust, and the instant setup means teams can be operational in minutes, not days.

Legal Document Exchange

Law firms and legal professionals regularly handle highly confidential case files, contracts, and evidence. RocketShare allows them to send these documents to clients, co-counsel, or experts with an auditable trail and the absolute assurance that the content is protected by zero-knowledge encryption, maintaining attorney-client privilege and compliance with data protection regulations.

Healthcare Data Sharing

Medical practices, therapists, and healthcare administrators can use RocketShare to safely transmit patient records, lab results, and insurance information. The platform's robust encryption ensures Protected Health Information (PHI) remains confidential, helping organizations meet strict HIPAA and GDPR requirements for data security and patient privacy during digital communication.

Creative Asset Delivery

Photographers, videographers, and marketing agencies can deliver high-resolution portfolios, campaign assets, and draft edits to clients without fear of unauthorized access or piracy. The sender controls the link expiry, and the encryption guarantees that only the intended recipient can view the final creative work, protecting intellectual property.

Secure Financial Collaboration

Accountants, financial advisors, and business owners need to share sensitive spreadsheets, tax returns, and audit reports. RocketShare provides a secure channel for this collaboration, ensuring that financial data is never exposed. Teams can confidently collaborate on sensitive projects, knowing the files are encrypted end-to-end.

RocketShare is a secure file-sharing platform designed with one core principle: your privacy is non-negotiable. It allows individuals and businesses to send files of any size with the confidence that no one, not even RocketShare itself, can ever access the content. This is made possible through a zero-knowledge encryption model, where your files are encrypted on your own device before they ever touch the internet. The encryption key stays with you, often embedded in the share link itself, meaning the servers only ever handle unreadable, encrypted data. This approach provides enterprise-grade security in a beautifully simple, self-serve package. Whether you're a lawyer sending sensitive case files, a photographer delivering client galleries, or a team collaborating on confidential projects, RocketShare ensures your intellectual property and private data remain exactly that—private. With options for both cloud-based and local "peer-to-peer" sharing, and data stored securely in the EU, it’s the perfect tool for anyone who values simplicity without compromising on top-tier security.

How do I start using Caller?

Getting started is incredibly easy and free. First, visit the Caller website and sign up for an account in seconds—no credit card is required initially. Once your account is created, you can add funds to your wallet using a secure payment method. Then, simply enter the phone number you wish to call in the browser interface and click the call button to connect instantly.

Do I need to download any software or app?

No, you do not need to download any software, apps, or browser extensions. Caller is a fully web-based (WebRTC) service. You can make and receive calls directly through your modern web browser on your desktop, laptop, tablet, or smartphone, ensuring easy access from any device with an internet connection.

What is the call quality like?

Caller uses enterprise-grade infrastructure to deliver High-Definition (HD) voice quality on your calls. This means you can expect crystal clear audio with minimal delay or distortion, making conversations feel natural and seamless, as if you were speaking to someone in the same room.

Are my calls and payments secure?

Absolutely. Caller employs bank-level security measures to protect your privacy and data. All calls are encrypted with SSL, and payment transactions are processed securely. The company adheres to a strict no-hidden-fees policy, ensuring your financial information and conversations are safe.

How does zero-knowledge encryption protect my files?

With zero-knowledge encryption, your files are encrypted on your device with a key only you possess. RocketShare's servers never receive this key, so they only store encrypted, unreadable data. Even if someone accessed the servers, they couldn't decrypt your files. Only someone with the unique link containing the key fragment can decrypt and view them, giving you ultimate control.

Where are my files stored?

All files uploaded via RocketShare's Cloud Share are stored on secure servers located within the European Union. This ensures that your data is protected under the EU's strong data protection laws (GDPR). The files are stored exclusively in their encrypted state, so the storage provider only ever handles scrambled data.

What is the difference between Cloud Share and Local Share?

Cloud Share uploads your encrypted file to RocketShare's secure servers, generating a link you can share with anyone. It's great for asynchronous sharing. Local Share (coming soon) establishes a direct connection between your device and the recipient's device to transfer the file without it going to any server, ideal for maximum privacy on the same network.

Do I need a credit card to start using RocketShare?

No, you do not need a credit card to start using RocketShare. You can sign up and begin using the service for free to experience its secure file-sharing capabilities. This allows you to test the privacy features and workflow before committing to a paid plan, if needed.
