Extension Metadata

About this extension
FitCheck helps you choose the right size faster while shopping online.

Enter your body measurements once, open a product page, and click Check My Fit. FitCheck detects available size-chart information on the page and compares it with your saved measurements to recommend a likely best size.

What you get
- A recommended size based on chart ranges
- Confidence level for the recommendation
- Measurement-by-measurement fit breakdown
- Alternative size suggestion when relevant
- Automatic centimeter/inch handling for chart comparisons

How it works
- You enter measurements in the extension popup (for example: chest, waist, hips, inseam, shoulder, neck, height).
- On demand, FitCheck reads the current product page for size-chart tables and fit-related chart structures.
- FitCheck runs local matching logic to map your measurements to chart ranges and displays the result in plain language.

Designed for real shopping flow
- Works across many retailer domains
- Built for quick repeated checks
- Keeps your saved measurements locally for convenience

Privacy and data handling
- Measurements and preferences are stored locally in your browser.
- No account required.
- No ads and no sale of personal data.
