1. Overview

Link to GUI is a lightweight Windows utility that registers the sap:// URL protocol and forwards URL parameters to the SAP GUI shortcut launcher (sapshcut.exe), enabling one-click SAP transaction launch from a browser.

Link to GUI does not connect to the internet. It does not transmit, store, or process any personal data on remote servers. All processing happens locally on your device.

2. Data we collect

Link to GUI collects no personal data. Specifically:

The only data Link to GUI processes is the sap:// URL passed to it by the browser at the moment you click a link. This URL is parsed in memory, used to construct arguments for sapshcut.exe, and immediately discarded. It is never written to disk by Link to GUI itself.

3. Data we do NOT collect

4. How data is used

Link to GUI uses the URL passed by the browser solely to launch the SAP GUI transaction you requested. No data leaves your device as a result of using Link to GUI.

5. Data sharing

mkysoft does not share, sell, rent, or trade any data with third parties because Link to GUI does not collect any data in the first place. No third-party analytics, advertising, or tracking SDKs are included in Link to GUI.

6. Local-only processing

Link to GUI runs entirely on your local Windows machine. It does not require or use an internet connection. The executable communicates only with sapshcut.exe on the same machine via a standard Windows process launch call (Process.Start).

7. Windows registry usage

During installation or when you run Link2GUI.exe --register / --register-user, Link to GUI writes the following registry keys to register the sap:// URL protocol handler:

These keys contain only the path to Link2GUI.exe and the string "Link to GUI". No personal data is stored in the registry by Link to GUI. The keys are removed automatically when you uninstall Link to GUI or run Link2GUI.exe --unregister / --unregister-user.

8. Third-party software (SAP GUI)

Link to GUI launches sapshcut.exe, which is part of SAP GUI published by SAP SE. mkysoft has no control over SAP GUI's data collection or privacy practices. Please refer to SAP's privacy statement for information on how SAP GUI processes data: https://www.sap.com/about/legal/privacy.html

9. Children's privacy

Link to GUI is a professional enterprise tool intended for use in corporate SAP environments. It is not directed at children under the age of 13. Because Link to GUI collects no personal data, it does not knowingly collect information from children.

10. Your rights and choices

Because Link to GUI collects no personal data, there is no personal data to access, correct, export, or delete. You may uninstall Link to GUI at any time using Windows Settings → Apps, which will remove the application and its registry entries from your device.

You can also manually remove the sap:// registration at any time by running:

11. Security

Link to GUI is a compiled, signed Windows executable distributed via the Microsoft Store. It runs with standard user privileges when handling URLs (no UAC prompt on link click). Registry writes require elevation, which is handled by the MSI installer or when you explicitly run the registration commands.

URL parameters are validated and URL-decoded in memory before being passed to sapshcut.exe. No shell interpolation is used; arguments are passed via ProcessStartInfo.ArgumentList to prevent injection.

12. Changes to this policy

If we make material changes to this privacy policy, we will update the effective date at the top of this page and, where appropriate, notify users through the Microsoft Store update notes. We encourage you to review this policy periodically.
