Your Private Cloud.
Securely Encrypted.

No. Files and filenames are encrypted directly upon upload with AES-256-GCM. Without your password, neither we nor any third parties can read the content.

Darkdrive uses AES-256-GCM encryption, split-key authentication, CSRF protection, rate limiting, strict Content Security Policies, and automatic memory zeroing. Only with complete, unauthorized server access could data be intercepted during upload or viewing.

Yes. The decryption password can be changed via Emergency Mode, which decrypts all files and filenames and re-encrypts them with the new password. This function is directly accessible via the server in the Self-Host plan; in the Managed plan, it can be activated upon request.

Your password is the only key to your data. Since it is not stored anywhere—neither in plain text nor in a derivable form—your files cannot be recovered without the password. We therefore recommend creating regular backups using the export function.

Keep your decryption password in secure locations only. Sessions expire automatically after 12 hours; manually logging out will immediately remove cached data.

Darkdrive supports over 80 file types across nine categories: images (JPG, PNG, GIF, WebP, SVG, AVIF, HEIC, etc.), audio (MP3, FLAC, OGG, WAV, etc.), video (MP4, MKV, MOV, WebM, etc.), documents (PDF, DOCX, XLSX, PPTX, ODT, etc.), archives (ZIP, RAR, 7z, TAR, etc.), text and code (TXT, MD, CSV, JSON, PY, JS, etc.), fonts, contacts (VCF), and design files (PSD, Sketch, Figma, etc.).

Images, videos, and audio can be viewed or played directly in the browser. PDFs open natively in the browser, and office documents receive an encrypted preview of the first page. Audio files automatically detect cover images within the same tag and display them as thumbnails. Encrypted thumbnails are generated automatically for all supported file types.

Yes. Text-based files such as TXT, MD, CSV, JSON, HTML, CSS, and numerous programming languages can be edited directly in the detail view, provided they are smaller than 2 MB. Changes are automatically re-encrypted on save. New text-based files can also be created directly.

Tags allow thematic organization of files. Multiple tags can be assigned to each file, and the file overview can be filtered by individual tags. Using multi-select, multiple files can be tagged at once. Entering a tag again removes it. All tags are stored encrypted.

Yes. Individual files can be shared as a decrypted copy via a temporary link. Access can be revoked at any time. The original file remains fully encrypted throughout – only the shared copy is accessible without a password.

Individual files can be downloaded directly from the detail view. For a full export, a decrypted ZIP archive containing all files – or files filtered by tag or type – can be downloaded. Using multi-select, specific files can also be exported as a bundle.

A separate synchronization tool enables automatic two-way file sync. New or modified files are downloaded as decrypted backups, and files placed in an upload folder are automatically uploaded and encrypted.

Yes. The interface is fully responsive and optimized for mobile browsers. Using the "Add to Home Screen" feature, Darkdrive can be used like a native app.
