ShareBox

Product Introduction

1. ShareBox is a macOS application designed to enable secure and rapid file sharing through cloud-based temporary links. It integrates directly with macOS Finder, allowing users to upload files or folders via right-click context menus or drag-and-drop actions. The app generates encrypted, shareable links that expire automatically after 7 days, ensuring no long-term data retention.
2. The core value of ShareBox lies in its emphasis on privacy, speed, and minimalist design for macOS users. It eliminates the complexity of traditional cloud storage by focusing on transient file transfers with end-to-end encryption and automated cleanup. The app prioritizes user experience with native macOS optimizations, ensuring seamless performance on devices running macOS 14 or newer.

Main Features

1. ShareBox enables drag-and-drop or right-click uploads directly from macOS Finder, bypassing browser-based interfaces or standalone cloud storage platforms. Files are uploaded to secure servers using TLS 1.3 encryption, and users receive a unique, time-limited URL immediately after upload.
2. Every file or folder shared through ShareBox is automatically deleted after 7 days, with no option for manual extension, ensuring compliance with data minimization principles. Expired links return a 404 error, and all associated metadata is purged from servers to prevent recovery.
3. The app provides instant notifications when recipients access shared links, including timestamps and IP address logs for audit purposes. Users can revoke access prematurely via the app’s dashboard, overriding the 7-day expiration window if needed.

Problems Solved

1. ShareBox addresses the inefficiency and security risks of sharing large files via email or permanent cloud storage platforms. Traditional methods often expose users to data breaches or require cumbersome account setups, which ShareBox eliminates through ephemeral links and zero user authentication.
2. The target user group includes macOS professionals, developers, and teams requiring frequent, secure file exchanges without long-term storage commitments. It is particularly suited for industries like legal, healthcare, or freelance design, where temporary data access is critical.
3. Typical use cases include sending project drafts to clients, sharing sensitive documents with expiration guarantees, or transferring large media files that exceed email attachment limits. Developers can use ShareBox to distribute beta software builds securely.

Unique Advantages

1. Unlike cross-platform tools like WeTransfer or Dropbox, ShareBox is built exclusively for macOS 14+ using Swift and SwiftUI, ensuring deeper system integration and faster performance. It leverages macOS-native features like Finder extensions and Metal-accelerated UI rendering.
2. The app’s “temporary by design” architecture ensures no files persist beyond 7 days, a feature absent in most competitors that rely on manual deletion or paid plans for expiration settings. This automation reduces user effort and mitigates accidental data exposure.
3. Competitive advantages include end-to-end encryption for both in-transit and at-rest data, a no-signup-required model, and adherence to Apple’s privacy guidelines. ShareBox avoids third-party trackers and does not collect user metadata beyond operational requirements.

Frequently Asked Questions (FAQ)

1. How long do files remain accessible in ShareBox? Files are available for 7 days after upload, after which they are permanently deleted from servers. Users cannot extend this period, ensuring compliance with strict data retention policies.
2. Is ShareBox compatible with older macOS versions? The app requires macOS 14 or newer due to its reliance on SwiftUI 5 and Metal 3 optimizations. It is not backward-compatible with macOS Ventura or earlier releases.
3. What file types and sizes does ShareBox support? ShareBox supports all file types without restrictions, including folders, and imposes no size limits due to its chunked upload technology. Upload speed depends on the user’s internet bandwidth.
4. How does ShareBox ensure data security? Files are encrypted using AES-256 during transit and storage, and links are generated with cryptographically random tokens. The app does not store encryption keys, making decryption impossible after deletion.
5. Can recipients download files multiple times? Yes, recipients can download files repeatedly until the link expires or is manually revoked. ShareBox does not impose download limits or require recipient authentication.
