Description
MethodGrid Maler-Kostenrechner is a focused estimate calculator for German painting businesses that want a simple alternative to a generic form or calculator builder.
Site operators enter their own rates, add a note explaining the price basis, choose an accent color, configure a contact link, and place the calculator with the shortcode [malerpreis_rechner].
Visitors can enter wall and ceiling area, select the condition of the surfaces, add wallpaper removal and door painting, and receive a non-binding price range.
Key characteristics:
- Preconfigured workflow for standard interior painting estimates.
- The business enters its own pricing parameters; bundled numbers are demo values only.
- Demo values are blocked from public display until the operator explicitly confirms the settings.
- Optional room-dimension helper for estimating wall and ceiling area.
- Configurable minimum order value, estimate range and rounding.
- Configurable contact button and accent color.
- Calculation runs locally in the visitor’s browser.
- No lead form, tracking, cookies, external APIs, external fonts or visitor-data storage in version 1.0.0.
MethodGrid Maler-Kostenrechner is currently designed for German-language painting businesses and uses EUR for estimates.
The result is an estimate, not a binding quotation. The site operator is responsible for entering appropriate business-specific prices and wording.
Privacy
Version 1.0.0 stores only administrator-configured plugin settings in the WordPress options table. The plugin itself does not store personal visitor data, set cookies, use local/session storage, or send external requests.
The contact button is a normal link configured by the site operator. When a visitor follows that link, the privacy behavior of the destination page, email client or phone application is outside this plugin’s control.
Support
For support after publication, use the plugin’s WordPress.org support forum. Please include your WordPress version, PHP version, active theme, and steps to reproduce the issue.

FAQ
-
Are the default prices market recommendations?
-
No. They are demo values only. The public calculator remains locked until the site operator explicitly confirms the stored settings.
-
Is the result a binding quotation?
-
No. The frontend labels the result as a non-binding estimate. The business can also add its own price-basis note below the result.
-
Does the plugin collect leads or personal visitor data?
-
No. Version 1.0.0 has no lead form and does not store personal visitor data. The configured contact button only links to an existing contact page, email address or phone number.
-
No. The plugin code does not set cookies, use browser local/session storage, load external fonts, send analytics, or call external APIs.
-
Can I change the calculator colors?
-
Yes. You can choose one accent color in the settings. The plugin derives matching hover, selection, button-text and focus colors automatically.
-
Can I use several calculators on the same page?
-
Yes. Multiple shortcode instances are scoped independently.
-
What happens if JavaScript is disabled?
-
The calculator does not calculate prices and displays a message explaining that JavaScript is required.
