SugarCalc isn’t just another widget. It’s a robust, medically-focused tool designed to add genuine value to your health or diabetes website.
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.
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.
Match your brand! Choose from pre-built clinic-suitable themes or customise colours to blend seamlessly with your WordPress site.
Built with modern, modular vanilla JavaScript. Core conversion logic is 100% unit-tested with Vitest. Clean, well-structured code with no conflicting dependencies.
Supports both mmol/L and mg/dL units, making your health content accessible to a worldwide audience without confusion.
It's more than just a converter. SugarCalc provides contextual, evidence-based information on diabetes-related issues such as hypoglycaemia, hyperglycaemia, and ketoacidosis.
Don’t settle for a widget that looks out of place. SugarCalc Pro includes 6 meticulously designed WCAG 2.1 AA compliant colour schemes to integrate with your chosen WordPress theme.
SugarCalc Agency extends that further with 6 ‘Dark Mode’ schemes and a Custom Editable Colour Scheme with a WCAG 2.1 AA compliance checker so you can match your website colours exactly.

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 the Freemius diagnostic programme, Freemius handles that data under its own privacy policy and obligations, which you can review at the links in the Description section.

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.

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.
