Internxt is a cloud storage service used by individuals and privacy-conscious users around the world on Windows, Mac, Linux, Android, and iOS. It provides zero-knowledge encrypted file storage, automatic photo and folder backup, cross-device sync, and secure file sharing, all within a clean and straightforward interface built around a privacy-by-default approach. This review takes a neutral and practical look at what the service does well, where it performs consistently, and who is most likely to find it useful.

Internxt is a Spain-based company that positions itself as a privacy-focused alternative to mainstream cloud storage services such as Google Drive and Dropbox. Its key architectural distinction is that files are encrypted and fragmented on the user’s device before being uploaded, meaning Internxt has no technical ability to access stored content. The service is open source and has undergone independent security audits.

For users who want encrypted cloud storage without the complexity of a tool like Cryptomator — which adds encryption on top of an existing provider — Internxt offers a self-contained solution where privacy protection is built into the service from the ground up.

What Is Internxt

Internxt is a zero-knowledge cloud storage service designed for individuals who want to store personal files, photos, and documents in the cloud with strong privacy protections. It supports Windows, Mac, Linux, Android, and iOS, with a web interface also available for browser-based access from any device.

Files uploaded to Internxt are encrypted on the user’s device before transmission using AES-256 encryption. The encryption keys are held by the user and are never transmitted to Internxt’s servers, meaning the company has no ability to view, access, or share stored content. Files are also fragmented before upload — split into pieces distributed across multiple storage nodes — which provides an additional layer of protection against unauthorized access.

Internxt includes automatic backup for local folders and photos, cross-device sync for keeping files current across all linked devices, and secure sharing tools for sending files or folders to others. The interface is designed to be clean and accessible, avoiding the feature complexity of enterprise-oriented storage platforms.

Key Features

Zero-Knowledge Encrypted Storage Files are encrypted locally on the user’s device using AES-256 before being uploaded. Internxt holds no encryption keys and has no technical means to access the contents of stored files. In tested scenarios, this architecture ensures that the storage provider cannot read user data even if its servers are accessed by a third party.

File Fragmentation Before Upload In addition to encryption, files are fragmented into smaller pieces before being distributed across multiple storage nodes. This means that even if individual storage nodes were accessed, the fragments would be meaningless without the full set and the decryption key. This approach provides an additional layer of protection beyond standard encrypted cloud storage.

Automatic Photo and Folder Backup Internxt supports automatic backup of local folders and photo libraries to the encrypted cloud vault. Backups run in the background without requiring manual uploads, keeping a secure remote copy of selected directories current as files change on the local device.

Cross-Device Sync Files stored in Internxt sync automatically across all linked devices. Changes made on one device are reflected on others without manual intervention, making it practical for users who work across desktop and mobile platforms.

Secure File Sharing Individual files and folders can be shared with others through generated links. Sharing links can be protected with a password and set to expire after a defined period, giving users control over who can access shared content and for how long.

Open Source and Audited Internxt’s client-side applications are open source, with code publicly available for independent review. The service has undergone independent security audits, and results have been published — a level of transparency uncommon among consumer cloud storage providers.

Performance Review

Upload and Download Speeds In tested scenarios, Internxt delivers acceptable upload and download speeds for everyday file types including documents, photos, and moderate-sized archives. As a smaller provider compared to Google Drive or Dropbox, speeds can vary depending on server load and geographic location, and heavy transfers of large video files may be slower than with larger mainstream services.

Sync Reliability In tested scenarios, cross-device sync functions reliably for standard file types and folder structures. The desktop client maintains sync status in the background with low resource usage. Occasional sync delays with large files or during periods of high activity have been noted by some users, which is not unusual for a growing independent storage service.

Backup Performance Automatic photo and folder backup operates in the background without requiring manual input. In tested scenarios, the initial backup of large photo libraries takes time proportional to the volume of data, with subsequent incremental backups completing more quickly as only changed files are processed.

Interface and Usability The interface is clean and minimal, making it easy for general users to upload, organize, and share files without a steep learning curve. The web interface, desktop apps, and mobile apps share a consistent design language, and the core features are accessible without requiring configuration or technical knowledge.

Pricing & Plans

Internxt offers a free plan that includes a modest amount of storage — sufficient for light use but limited for users who want to store large photo libraries or document archives. Paid plans are available with significantly larger storage capacities, offered as monthly or annual subscriptions. Lifetime plans have also been available at various points, which can represent strong long-term value for users who want to avoid ongoing subscription costs.

Internxt is generally priced competitively against privacy-focused alternatives such as Proton Drive and Tresorit, and below mainstream services when comparing storage capacity per cost at paid tiers.

Current pricing, plan details, and any available lifetime options are listed on the official Internxt website.

Use Cases

Users Who Want Privacy-by-Default Cloud Storage Internxt is well suited for individuals who want the convenience of cloud storage without relying on providers such as Google or Microsoft that have business models involving data access. The zero-knowledge architecture removes the need to trust the provider with file contents.

Users Backing Up Photos and Personal Documents The automatic photo and folder backup features make it a practical option for users who want a secure remote copy of their photo library and important files without manually managing uploads.

Users Looking for a Cryptomator Alternative Where Cryptomator adds encryption on top of an existing cloud provider, Internxt provides encryption and storage as a unified service — a simpler setup for users who do not want to manage two separate tools.

Privacy-Conscious Users Who Prefer Open-Source Software The open-source client applications and published audit results make it a credible option for users who want to verify the privacy claims behind the service independently.

Pros and Cons

  • Zero-knowledge encryption with file fragmentation provides strong privacy protection — Internxt cannot access stored content
  • Open-source client applications with published independent security audits
  • Automatic photo and folder backup runs in the background without manual management
  • Clean, accessible interface suited to general users without technical backgrounds
  • Competitive pricing at paid tiers compared to other privacy-focused cloud storage services
  • Lifetime plan options available periodically, which can offer strong long-term value
  • Smaller provider than mainstream services such as Google Drive or Dropbox, with upload and download speeds that may vary more depending on server load and location
  • Free plan storage is limited, making a paid subscription necessary for users with larger storage needs
  • Sync reliability with very large files or high-volume transfers can be less consistent than established mainstream providers
  • Feature set is narrower than enterprise-oriented storage platforms — collaboration and real-time document editing are not supported
  • As a growing independent service, long-term business continuity carries more uncertainty than larger, established providers

Who Should Consider This Software

Internxt is a strong fit for privacy-conscious individuals who want encrypted cloud storage without the complexity of layering a tool like Cryptomator on top of an existing provider. It is particularly well suited for users who store personal photos and documents in the cloud and want assurance that the storage provider cannot access their files, those who prefer open-source software with verifiable security, and users looking for a self-contained privacy-focused alternative to Google Drive or Dropbox.

Users who need high-speed transfers for large media files, real-time document collaboration, or the stability of a large established provider may find mainstream services or enterprise-focused alternatives more suitable. For everyday personal file storage with strong privacy protections, Internxt is a capable and cost-effective option.

Final Verdict

Internxt delivers on its core promise of privacy-first cloud storage with a clean interface and a verifiable zero-knowledge architecture. File fragmentation before upload, open-source code, and published security audits place it in a credible position among privacy-focused storage services, and its pricing is competitive for the level of protection offered.

The main trade-offs are the limitations common to smaller independent providers — variable transfer speeds and less extensive infrastructure compared to mainstream services. For users whose priority is keeping personal files genuinely private in the cloud, Internxt is a well-built and accessible option worth considering.
