Terms of Use

1. Use at your own risk

Weimer Network Defender modifies the behavior of background processes and network connections on your operating system. While the software is designed with safety in mind, you understand and agree that:

• You are solely responsible for any consequences arising from your use of the software.
• You decide which services to allow, kill, or firewall — the software follows your instructions.
• Terminating system processes can in some cases lead to unexpected behavior, including system freezes, application crashes, or the temporary loss of features (e.g. iCloud sync, push notifications, Spotlight indexing).
• The aggressive "Auto-Kill IMMEDIATELY" mode is documented as a power-user feature. Use it only on processes you have identified and understood.

2. No warranty

The software is provided "as is", without any warranty of any kind — express or implied — including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement.

We do not warrant that the software will be uninterrupted, error-free, or compatible with every macOS configuration, version, or third-party software you may run.

3. Limitation of liability

To the maximum extent permitted by applicable law, Weimer Software shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages — including but not limited to data loss, system instability, lost revenue, or interruption of service — arising out of or in connection with your use of the software.

This limitation applies regardless of the legal theory under which the claim is made (contract, tort, negligence, or otherwise), even if we have been advised of the possibility of such damages.

4. Recovery

If a decision you made through the software causes your Mac to become unstable, you can always recover by booting into Safe Mode and running the appropriate command-line utility (documented in the product) to undo the change. No setting is permanent.

5. License

A purchased license grants you the right to install and use the software on up to three Macs that you own or control. The license is non-transferable. Reverse engineering, redistribution, or resale of the software is not permitted.

6. Refunds

We offer a 14-day refund window, no questions asked. Refunds are processed through our payment provider (Polar). Contact service@weimersoftware.com to request one.

7. Governing law

These terms are governed by the laws of the Federal Republic of Germany. Place of jurisdiction is Baden-Baden, Germany, to the extent permitted by law.

8. Changes to these terms

We may update these Terms of Use from time to time. The version that was in effect at the time of your purchase or last download applies to you.
