Privacy Policy
Effective Date: November 2, 2026. Your body dimensions are deeply personal. We designed Perfect Size Calculator so that your measurements never touch our servers.
1. Zero Collection of Personal Measurements
When you type measurements into our calculators (waist, hips, inseam, bust, or foot length), that data remains entirely in your device's local browser memory. No measurement numbers, sizing outputs, or personal body traits are transmitted across the internet, logged into server files, or sold to third parties.
2. Local Execution
All calculation logic runs client-side using JavaScript. When you click “Calculate,” the mathematical comparison takes place right on your phone or laptop. Closing or refreshing the tab completely wipes your entered data from memory.
3. No Accounts, Passwords, or Photos
We will never ask you to create an account, provide an email address, or upload full-body photos to find your clothing size.
4. Analytics & Infrastructure
We may collect basic, anonymous aggregated website telemetry (e.g. general page views, browser device types, or 404 error occurrences) to monitor uptime and site performance. This telemetry contains no identifying information or sizing inputs.
