Privacy Policy

Introduction and Our Privacy Commitment

16TypeTalk ("we," "our," or "us") is built on a simple principle: your thoughts and reflections are yours. This Privacy Policy describes what information we collect, why we collect it, how we use it, and the choices you have about your data.

We have written this policy in plain language — not to hide anything, but to be genuinely transparent. We believe you deserve to understand exactly how your data flows through our service.

This Privacy Policy covers the 16TypeTalk mobile application and any related services (collectively, the "Service"). By using the Service, you agree to the practices described here.

About 16TypeTalk

16TypeTalk is an AI-powered personal reflection application. The Service presents multiple MBTI-inspired personality perspectives ("the Council") in response to situations, decisions, or questions you share. Our goal is to help you think more clearly by offering diverse, structured viewpoints — not to replace human connection, professional advice, or therapy.

MBTI® and Myers-Briggs Type Indicator® are registered trademarks of The Myers & Briggs Foundation. We are not affiliated with or endorsed by The Myers & Briggs Foundation. Our use of MBTI-inspired concepts is for self-reflection and entertainment purposes only.

These providers act as data processors on our behalf. They are contractually prohibited from using your prompts to train their models without separate disclosure and consent.
