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.
2. Data we collect
Link to GUI collects no personal data. Specifically:
- No analytics or telemetry data is collected or sent.
- No crash reports are sent to any server.
- No usage statistics are recorded.
- No account creation or login is required.
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
- Name, email address, or any contact information
- IP address or network identifiers
- Device identifiers or hardware fingerprints
- Browser history or browsing behaviour
- SAP credentials, system names, or transaction data from URLs
- Location data
- Cookies or tracking identifiers
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:
-
All-users install (HKLM):
HKEY_LOCAL_MACHINE\Software\Classes\sap -
Per-user install (HKCU):
HKEY_CURRENT_USER\Software\Classes\sap
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:

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:
Link2GUI.exe --unregister(removes HKLM entry, requires admin)Link2GUI.exe --unregister-user(removes HKCU entry)
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.
