## License Terms

### 1. **Restrictions on Use & Modification**

You may **NOT**:

- Modify, adapt, alter, or create derivative works of this software
- Remove or obscure any proprietary notices, labels, or marks
- Redistribute, republish, or repackage this plugin as your own product
- Distribute modified versions of this software
- Bypass, disable, or circumvent the license validation mechanisms
- Create or distribute unlicensed versions based on modified code

You are permitted to read and understand the source code for personal learning, but any modifications are prohibited.

You may use this software freely within the scope permitted by Section 2 below.

### 2. **Permitted Use**

**Free Features:** You may use the free features (viewing time series and models, basic plotting) without a license or with a free tier license.

**Pro Features:** Advanced features (model solving, editing) require a valid Pro or ProNL license that is currently active and not expired.

In either case, you must comply with all other terms in this agreement.

### 3. **License Validation**

For paid (Pro/ProNL) features, this plugin requires online license validation. The software will:

- Attempt to contact the license server at startup
- Validate your license key and machine for Pro features
- Disable paid features if validation fails or is disabled
- Free features remain available without validation

Strictly online licensing is enforced without local workarounds for paid features.

### 4. **Prohibition on Unlicensed Redistribution**

**Circumventing or removing the license validation to create an unlicensed version is explicitly forbidden.** This includes:

- Modifying if-statements or conditional logic to bypass license checks
- Removing the `license_manager` module
- Redistributing modified versions as "free" alternatives
- Creating forks that disable licensing enforcement

**Violation may result in legal action, including but not limited to:**
- Takedown notices under EU Copyright Directive Article 6 (2001/29/EC) or equivalent national implementation
- Civil litigation for copyright infringement under Dutch law
- Injunctive relief and damages

### 5. **No Warranty**

This software is provided "as-is" without warranty of any kind, express or implied.

### 6. **Termination**

Your license to use paid features is automatically terminated if you violate any term of this agreement. Upon termination, you must immediately cease use of all Pro/paid features but may continue using free features in compliance with all other terms in this agreement.
