File names are encrypted too, not only what is inside the files.
How the encryption works
You put files in a vault
A vault is an encrypted folder with its own password, on your phone or your computer.
Your device encrypts them
File contents and file names are encrypted on the device with rclone crypt, an open and documented format.
Only encrypted data is stored
Your storage receives encrypted files. It can see that they exist, their approximate sizes and when they changed, but not what they are.
Your vault password and recovery key
A vault opens with its password or with its recovery key. We never receive either, so if you lose both, nobody can recover your files, not even us. Write the recovery key down and keep it away from the device.
Your files do not depend on us: with the recovery key you can decrypt them with the free rclone tool, without KhaznaTech.
Keep your vaults where you want
Each vault can live on different storage. The app connects straight from your device to it.
- On a device or drive
- A folder on your phone or computer, a USB drive or a network share.
- S3-compatible storage
- AWS, Backblaze B2, Wasabi, Cloudflare R2, MinIO, Hetzner and others.
- Google Drive
- You sign in with Google in your browser, and the app can only see the folders it creates.
- Your own server or NAS
- WebDAV (including Nextcloud), SFTP, Windows shares (SMB) and FTP.
- Storage you set up in rclone
- Already use rclone? Import the storage you configured there.

Phone and computer, in sync directly
Pair your phone and computer once by scanning a QR code; only paired devices can connect. On the same Wi-Fi they connect to each other directly. Anywhere else they connect through the KhaznaTech relay, end-to-end encrypted, so the relay only passes on encrypted data.
On Windows and Linux, KhaznaTech runs in the tray and can start with your computer.
Pro feature. Sync through the relay needs a free account.
Know when a backup did not run
When a backup fails or does not run on time, KhaznaTech alerts you:
- Telegram a message from the KhaznaTech bot
- Email to an address you have confirmed
- Webhook to your own systems, signed with a secret
Pro feature. Alerts need a free account.
Private from the start
- No ads.
- No analytics or crash-reporting SDKs: only an anonymous daily count of active installs, which you can switch off.
- An account is optional. Without one, the app does not contact our servers.
- With an account, our server never receives your file names, folder paths, file contents or vault passwords.
Questions
Can KhaznaTech read my files?
No. Files and their names are encrypted on your device before they are stored. Our servers never receive file contents, file names, folder paths or vault passwords.
What if I forget my vault password?
Open the vault with its recovery key instead. If you lose both, nobody can recover the files, not even us.
Do I need an account?
No. A free account is needed only for alerts, sync through the relay, activation codes and using one Pro licence on several devices.
Can I get my files back without KhaznaTech?
Yes. Vaults use the open rclone crypt format, so with your recovery key you can decrypt them with the free rclone tool.
Does the relay see my files?
No. Your devices encrypt the connection end to end with the keys they exchanged when you paired them, so the relay only forwards encrypted data. On the same Wi-Fi the relay is not used at all.
What does lifetime Pro mean?
One payment for Pro for as long as we offer and run KhaznaTech Pro. It is not tied to one device. Read the terms
How do I delete my account?
In the app, open Settings → Account → Delete account, or sign in on this website and delete it from the dashboard. How account deletion works
