What this site is
LeanLoss GLP-1 is a free, educational calculator. It does not require an account and does not collect your name, email, or contact information.
What you enter into the calculator
Your age, height, weight, activity level, medication selection, and goal weight are processed entirely in your browser to compute your results. We do not save these values to a database, and we do not associate them with you.
Optional photo upload (AI body-fat estimate)
If you choose to upload a photo for an AI body-fat estimate:
- The photo is resized in your browser and re-encoded to strip EXIF/location metadata before it leaves your device.
- It is sent over HTTPS to our serverless endpoint, which forwards it to the Lovable AI Gateway (Google Gemini) for a one-shot vision analysis.
- The photo is not stored on our servers or in any database. Only the numeric result is returned to your browser.
- We apply basic rate limiting (per-IP, in-memory) to prevent abuse. IP addresses are not logged to any persistent store.
Cookies and analytics
This site does not use advertising cookies. If hosting-provider analytics are enabled, they may collect anonymous request metadata (such as page paths and country) but no personal information from your calculator inputs.
Third parties
Photo analysis is performed by Google Gemini via the Lovable AI Gateway. Their handling is governed by their own terms; we do not retain copies of the photos we forward.
Children
This calculator is intended for adults (18+). It is not designed for, and should not be used by, minors.
Changes
If this policy changes, the “Last updated” date above will change.
