Your Privacy. Our Highest Priority.
Calculator inputs stay safely in your browser memory. Formulexa requires no accounts, saves no calculation history, and sells no personal information.
Privacy at a glance
No Accounts
V1 does not create accounts or save projects.
Local & Secure
Calculator inputs stay in your browser.
No Tracking
Analytics is cookieless and anonymous.
Transparent
Clear about what we do and don't collect.
Calculator data
Calculations run entirely in your local browser memory. Inputs are never uploaded to our server, never stored in persistent local database caches, and never recorded in product analytics.
Analytics and performance
When enabled in production, this site sends PostHog only explicit anonymous product events, and the only values it attaches are a tool name, category, and page path. Autocapture, automatic pageviews, replay recordings, heatmaps, and surveys are strictly disabled.
The intended PostHog project configuration is cookieless with client IP capture discarded. Vercel hosts the application and Speed Insights measures anonymous performance.
Contact messages
Name, email, topic, calculator selection, and message are transmitted directly to our project mailbox. Formulexa does not maintain an account or marketing database of past inquiries.
Abuse protection on the contact endpoint counts recent submissions per network address solely in volatile server instance memory for rate limiting.
