Welcome to Serge3DX
Serge3DX is a free, privacy-first online platform offering practical, evidence-informed tools to help individuals and couples understand their relationships better, navigate complex conversations, and build healthier digital connections.
Our Mission
We believe everyone deserves access to high-quality relationship tools — without subscriptions, data collection, or judgment. Every calculator, planner, and assessment on Serge3DX runs entirely in your browser, meaning your personal data never leaves your device.
The Tools We Build
Our tool library includes relationship compatibility calculators, date budget planners, NVC (Non-Violent Communication) conversation frameworks, milestone trackers, long-distance relationship planners, digital boundary assessors, and more. All tools are informed by established psychological frameworks including Gottman’s Four Horsemen research, Attachment Theory, and Nonviolent Communication methodology.
Evidence-Informed, Not Clinical
Serge3DX tools are designed for self-reflection, educational exploration, and communication support. They are not diagnostic clinical instruments and do not replace professional therapy, counseling, or mental health services. For serious relationship difficulties or mental health concerns, we strongly encourage consulting a licensed professional.
Privacy Commitment
100% of our tool computations happen client-side in your browser using JavaScript. We do not store, transmit, or analyze any of your responses. We do not use tracking pixels, behavioral advertising, or behavioral analytics on our tool pages.
