Questions, answered.
What encryption algorithm does Privaci use?
Privaci uses AES-256-GCM, the same encryption standard used by governments and financial institutions worldwide. It provides both confidentiality and integrity verification.
Can I preview encrypted files without decrypting them?
Yes. Privaci decrypts files in memory for preview — nothing is written to disk. When you close the preview, the decrypted data is immediately cleared from memory.
What happens if I forget my password?
Privaci uses zero-knowledge architecture — we never store or have access to your keys. If you lose your password, the encrypted files cannot be recovered. Your password is the only key — please write it down somewhere safe.
Which file types can I preview?
Privaci supports preview for images (PNG, JPG, GIF, WebP, SVG), documents (PDF, TXT, Markdown), and more formats are being added regularly.
Is my data sent to any server?
Never. All encryption and decryption happens entirely on your device. Privaci works completely offline — no internet connection required for any core functionality.
Which platforms are supported?
Privaci is available on macOS 13.0+ and Windows 10+. Both platforms share the same encryption format, so your files are portable across systems.
