Privacy Policy

Last updated: 2026

MTMODEX is built privacy-first. We collect the minimum needed to run the Service and never sell personal data.

Data we process

Account: if you sign in, we store your email address to authenticate you and associate your subscription. Authentication is handled by Supabase.

Billing: payments are processed by Lemon Squeezy. We do not store card details; we keep your subscription status only.

Calculations & history: free calculation history is stored locally in your browser. Premium projects are synced to our database so you can access them across devices.

Analytics: we use Plausible, a privacy-friendly, cookieless analytics tool that records aggregate usage only — no personal profiles, no cross-site tracking, no cookie banner required.

Advertising: the free tier may show Google AdSense ads. Premium users see no ads.

Your rights

You can request access to or deletion of your account data at any time by contacting us. Deleting your account removes your profile and synced projects.
