Our Core Values

🔒

Privacy First

Your emotional data stays on your device, period. No cloud sync, no data mining, no exceptions.

🧠

Science-Based

Every feature is grounded in peer-reviewed research from psychology and behavioral neuroscience.

💜

Empathy-Driven

We design with deep understanding of mental health challenges, having walked this path ourselves.

Simplicity

Mental health tools should reduce stress, not add it. We obsess over making complex insights feel effortless.
