What It Is

BOZON.CC is an online note-taking app focused on security and privacy, with client-side encryption and a zero-knowledge architecture as its core selling points. Users’ notes, folders, files, and even data structures are encrypted on the device, while the server only stores encrypted data. The product runs in the browser and emphasizes quick access from any device with a modern browser.

Core Features and Security

In terms of features, it supports unlimited nested folders, file attachments anywhere inside notes, multi-device sync, as well as client-side full-text search and regular expression search. Another notable feature is encrypted message transfer: users can securely send notes with text and attachments to other users using public-key asymmetric encryption. On the security side, BOZON.CC says it does not know users’ login passwords or encryption keys. After login, keys remain only in the device’s memory and are not sent to the server. Encryption uses the Salsa20 algorithm from the NaCl library, and data is stored in data centers in the Netherlands. The website also states that it does not track users through cookies, localstorage, logs, or similar methods.

Pricing and Plans

Pricing is straightforward: the free plan is $0 for life and includes unlimited notes and unlimited folders, with 50MB of file storage and 100MB of daily downloads. The paid plan costs $3/month and includes 10GB of file storage. The enterprise plan has variable monthly pricing and offers unlimited files. For personal secure note-taking, the free plan is quite usable, and the paid plan is also inexpensive. However, the enterprise plan lacks clear pricing rules and details on service scope.

Pros, Cons, and Who It’s For

The strengths are a clear encryption-first approach, instant browser-based access, unlimited notes on the free plan, and support for file encryption and encrypted transfers. The limitations are also obvious: there is no disclosed information on team permissions, admin controls, audit logs, third-party integrations, APIs, or developer support. The client code is only described as being open-sourced in the future, not currently open source. Official support channels only mention Twitter, and service assurance information is limited. It is better suited to individuals, privacy-sensitive users, and small-scale secure information management. Enterprises that need permission systems, compliance certifications, and centralized administration should evaluate it carefully.

Access from China and Alternatives

The official website does not provide information about access from mainland China, payment methods, or localization, so actual connectivity should be verified through testing. If access, payment, or collaboration features are limited, alternatives worth comparing include Standard Notes, Joplin, Notesnook, and Obsidian Sync. Users focused on team document collaboration may also consider Notion, 语雀, or 飞书文档, but their privacy models are not exactly the same as BOZON.CC’s.
