The Korean version is the authoritative text. Where the two differ in interpretation, the Korean version governs.
Summary
This app collects no personal information.
There is no account, no analytics, and no advertising. Everything you enter stays on your device, and the developer cannot see it.
1. Who operates this app
| Company | OSAN SOFT (오산전산) |
| Representative | Dongmin Song |
| Business Registration No. | 671-17-02657 |
| Contact | vigvadvoodoo@gmail.com |
2. What is stored on your device
The following stays on your device only and is never transmitted to any server.
| Data | Where | Protection |
|---|---|---|
| Connection profiles (host, port, username) | On-device database | Full database encryption (SQLCipher) |
| Passwords and key passphrases | On-device storage | AES-256-GCM with an Android Keystore-derived key |
| SSH private keys | On-device database | Same |
| Accepted server host keys | On-device database | Full database encryption (SQLCipher) |
| Command snippets | On-device database | Full database encryption (SQLCipher) |
On devices with StrongBox or a TEE, the master key never leaves the hardware.
Android auto backup is disabled (android:allowBackup="false") so that server credentials are not
carried into a Google account backup. If you want a backup, the app can export an encrypted file —
you choose that password, and the developer does not know it.
3. Network communication
The app talks only to the SSH servers you enter yourself.
Your connection details go only to the server you entered. Traffic is encrypted by the SSH protocol and the server’s identity is verified against its host key. The app never accepts a host key automatically — whether the key is new or has changed, it shows you the fingerprint and waits for your decision.
The developer’s infrastructure plays no part in this. The app sends nothing to the developer.
4. Third parties
The developer does not sell or share your information.
The app contains no third-party SDKs — no advertising network, no analytics, no push service.
5. What is never collected
- Usage statistics or analytics
- Advertising identifiers
- Location
- Contacts, photos, or files (other than key files you pick yourself and files you transfer over SFTP)
- Crash reports (none are collected automatically)
- Terminal input and output
6. Permissions
| Permission | Purpose | Required |
|---|---|---|
INTERNET | Connecting to SSH servers | Yes |
FOREGROUND_SERVICE | Keeping SSH sessions alive while the app is off screen | Yes |
FOREGROUND_SERVICE_DATA_SYNC | Declaring the type of that service (required on Android 14+) | Yes |
POST_NOTIFICATIONS | Showing the status notification while sessions are held open | Yes |
About the status notification. Android drops network connections once an app leaves the screen. Holding a session open requires a foreground service, and the system requires that service to show a notification for as long as it runs.
That notification shows only the number of open sessions and a button to disconnect them all. It does not contain server addresses, usernames, or terminal contents. It is displayed on the device and is not transmitted anywhere, nor does it pass through any push service.
Storage permission is never requested. File access happens only through the system file picker (SAF), and only for the file you select at that moment.
7. Retention and deletion
Everything stored on the device is deleted when you uninstall the app. The developer keeps no copy.
8. Your rights
Because the app neither collects nor stores personal information, there is nothing held by the developer to access, correct, or delete. Data on your device can be reviewed and deleted by you from within the app.
For any question, use the contact address above.
9. Children
This app is not directed at children under 13 and collects no information from them.
10. Changes
If this policy changes, the “last updated” date above changes with it, and any substantive change is noted in the app’s update description.
