By default, published and embedded calculators show a small "Powered by Numio" mark in the footer. On the Business plan you can turn it off. This article covers the toggle and where the watermark appears.
Plan note: Removing the watermark is a Business plan feature. On lower plans the toggle is shown with an upgrade pill, and switching it off prompts you to upgrade.
Where the watermark appears
The Numio mark renders in the footer of your live calculator — on both the General share view and the embedded iframe view. It's a subtle, semi-transparent logo that links back to Numio. It does not appear in single-page-view layouts.
Toggle it off
The watermark control lives in the editor's Settings panel:
- Open your project in the editor and go to the Settings panel.
- Find the Watermark switch.
- Turn it off to hide the "Powered by Numio" mark.
On the Business plan the change applies immediately to the project's branding. On lower plans, attempting to switch it off opens an upgrade prompt instead of changing the setting.
Publish to apply
Like any project setting, the watermark change only reaches your live calculator after you publish. Click Publish to push a new version with the watermark hidden — see Publish your project. Your existing share and embed links will then serve the watermark-free version.
Related branding
The watermark toggle is separate from your workspace branding (logo, accent color, font) and from the optional workspace icon you can show on a project. Hiding the watermark removes only the "Powered by Numio" footer mark; it doesn't affect your own logo or icon.
