Whats new in version 316

14 December 2025



New: framework upgraded


- In this release, we've upgraded our application's underlying technology from .NET Framework 4.5 to 4.8. We've held off on this change in the past to maintain low system resource usage, but this upgrade is now essential for security and compatibility as Microsoft ends support for older frameworks. You should not notice any difference in how the app looks or functions. As always, if you experience any unexpected behavior, please don't hesitate to reach out to us.

Patch 315

New: PIN recovery feature

- We're excited to introduce an important security feature: the ability to recover a forgotten PIN via email. This new recovery option is a logical addition to the PIN code security layer we introduced recently. For your security, the recovery feature is disabled by default. You can continue using your PIN as before, or you can enable email recovery in your settings for added convenience. Please remember that PIN is not the same as password, its a different things.
- Resolved an issue where the app icon did not display correctly in the taskbar for some users.

Patch 314

New: PIN code (second layer of security)

- New: Added a PIN code feature for securing app startup. This will be the second layer of security for your files located on the secret disk. The PIN protects application access, while the password remains the key for the secret disk itself, providing two distinct layers of security. This is a free function. With the next release we will add an option to recover forgotten PIN code via email.
- Adjusted: Refined the background colors in the common menu for improved visual consistency.
- Improved: Redesigned the common menu (accessed via the "3-dots" icon) to appear as a focused overlay, clearing the window content to minimize distraction and reduce visual clutter.
- Fixed: Resolved an issue where the app icon did not display correctly on the update screen.

Patch 313

Close disk on screensaver or Windows lock

- This release improves the tray agent's functionality with a new feature that allows you to quickly close the secret disk when the screen saver starts or Windows is locked. In other words, if you step away from your computer or close your notebook's lid, the disk can be closed instantly for security. This function is disabled by default and only works if the tray agent is enabled in the settings.

Patch 312

New: hotkey to close the disk

- New option: secret disk can be closed instantly by pressing the SHIFT + ESCAPE key combination on the keyboard. This functionality is only available if the tray agent is enabled within the application's settings.

Added few new great functions

- Say goodbye to tabs! The new settings screen is here with a sleek, clean design for a smoother experience.

- Premium features, when activated, now shine with a green label (instead of yellow) for better clarity.
- Unlimited Free Trial! We've removed the one-year limit - use the free version forever! Only premium features require a paid plan. Enjoy!

Patch 310

Two new security functions

- 2 New Security Functions
Available for all users.
1. Failed Login Alerts: Get notified if someone enters an incorrect password.
2. Auto-Shutdown Protection: Your computer can automatically shut down after failed login attempt.
Both features can be found in the app’s settings under the "Main" tab, giving you greater privacy and control over your secret disk.
- Design Update
Adjusted the main color scheme for a darker, more refined look.
- Bug Fixes
Fixed an issue where the "Update Later" button was incorrectly restricted to the Professional version - now available to all users.

Patch 309

New function: encryption level selection

- Encryption Level Selection. You can now select the encryption level to protect files on your secret disk. By default, no encryption is applied. Available options include:
1) Weak but extremely fast PkZIP encryption;
2) Modern AES encryption (two variants, with the strongest option being slower but highly secure).
Note: Encryption (and compression) is recommended for SSD disks or if your secret disk contains only a few files. For larger file collections (or HDD disks), enabling these features may take additional time depending on the data size.
To use this new function click "Preferences" and the select tab "Encryption".
- Improved "Install Later" Behavior. When clicking "Install later" (after detecting a new version), the app will now suppress update notifications for 7 days (previously just 1 hour). This feature is exclusive to the Professional version.
- Minor bug fixes and optimizations.
