Engineered for Healthcare Professionals
SugarCalc isn’t just another widget. It’s a robust, medically-focused tool designed to add genuine value to your health or diabetes website.
Privacy-First
All calculations happen client-side. No reading or health data ever leaves the visitor's browser or reaches a server, so our converter adds nothing for you to secure or report under HIPAA or GDPR.
Lightning Fast
Zero dependencies and no external API calls mean the converter loads instantly, and keeps working even if the visitor's connection drops after the page has loaded.
Multiple Colour Schemes
Match your brand! Choose from pre-built clinic-suitable themes or customise colours to blend seamlessly with your WordPress site.
Developer Friendly
Built with modern, modular vanilla JavaScript. Core conversion logic is 100% unit-tested with Vitest. Clean, well-structured code with no conflicting dependencies.
Global Standards
Supports both mmol/L and mg/dL units, making your health content accessible to a worldwide audience without confusion.
Built-in Medical Info
It's more than just a converter. SugarCalc provides contextual, evidence-based information on diabetes-related issues such as hypoglycaemia, hyperglycaemia, and ketoacidosis.

No. All conversions happen in the browser using JavaScript. No reading ever reaches a server. SugarCalc keeps no log of conversions and has no database of results.
The only thing the converter keeps is one flag in the visitor's browser session (sessionStorage), which records that they have accepted the medical disclaimer so it isn't shown again on every page. It contains no reading, and the browser deletes it when the tab is closed.
The converter never does. No blood glucose reading, calculation or anything you type is transmitted anywhere.
The plugin contacts Freemius only when you choose to: by opting in, or by activating a licence. The Upgrade link opens sugarcalc.com in your browser. If you skip the opt-in, SugarCalc makes no external connections.
If you opt in, Freemius receives your name and email address; basic website details (homepage URL and title, WordPress and PHP versions, site language); and the versions of SugarCalc and the Freemius SDK, and whether SugarCalc is active, deactivated or uninstalled. The opt-in screen also offers to share a list of your installed plugins and themes (names, versions and whether each is active). That option starts switched off, and nothing from it is sent unless you switch it on.
For more details please see:
* Freemius Privacy Policy
* Freemius Terms of Service
SugarCalc was built with a privacy-first architecture. The converter collects no personal data. All calculations happen entirely within the visitor's browser (client-side). No blood glucose reading, and no health data of any kind, is ever transmitted to our servers or stored in your WordPress database. The converter holds no personal data, so it adds nothing for you to secure or report under data protection law.
HIPAA and GDPR obligations apply to your organisation and how it handles data overall, not to a single plugin. SugarCalc is designed so the converter adds no personal data for you to account for. Please confirm your own obligations with your legal or compliance adviser.
If you opt in to Freemius, Freemius handles that data under its own privacy policy and obligations: see the Freemius Privacy Policy.
SugarCalc is designed to WCAG 2.1 AA, and the colour contrast of every scheme has been audited against it.
Yes. The free version comes with our standard Minimal Mono theme, a clean black, grey, and white design.
The Professional version includes all 5 Professional Colour Schemes, and the Agency adds 6 more Premium Dark Colour Schemes.
The Agency version also includes a Custom Editable Colour Scheme you can match to the exact colours of your website. It will also check your custom colours and warn you if their contrast falls below the WCAG 2.1 AA level and won't save them until it's fixed.
The Agency version has further features to control more style elements such as corner rounding and divider lines.
If you need something completely unique, we also offer custom development services to tailor the plugin exactly to your brand guidelines.

Yes. The interface is responsive and works on phones and tablets of all sizes.
Yes. SugarCalc works with Elementor and other major WordPress page builders that support shortcodes. You can insert the converter using a simple shortcode.
Add [sugarcalc] by typing it as a shortcode in any page, post, or text widget. In the block editor, add a Shortcode block and type [sugarcalc] inside it. The converter will appear in place of the shortcode when the page loads.
No. SugarCalc is very lightweight. SugarCalc loads its scripts and styles only on pages that include the '[sugarcalc]' shortcode. The converter front-end has zero external dependencies (no jQuery, no external API calls) and is built with modern, plain JavaScript. It makes no external CDN requests and no remote API calls during normal operation. The total asset footprint is very small.
SugarCalc provides contextual, evidence-based information based on the entered reading. It covers scenarios such as hypoglycaemia, hyperglycaemia, and ketoacidosis.
SugarCalc always includes a clear disclaimer that it is an informational tool, not a replacement for professional medical advice.
The plugin applies thresholds from the ADA (American Diabetes Association) and NICE (the National Institute for Health and Care Excellence in the UK).
You can review the threshold values on our Blood Glucose Thresholds page.
SugarCalc displays a disclaimer stating that the tool provides general information only and is not medical advice. You should seek your own legal advice about the disclaimer wording for your jurisdiction and your specific audience.
Yes. We offer email support on all Pro and Agency licences.
Yes. We offer a 100% Money Back Guarantee on all Pro and Agency licences.
