1. Purpose of Stellia and Important Notice

1.1. Purpose of the Application

It notably allows you to:

  • track your emotional state using visual avatars (stars) and personalized pillars (life domains);
  • add comments and, where applicable, photos linked to certain check-ins;
  • create a ”galaxy” / ”tribe” and share certain information with selected members;
  • benefit from AI coach features (e.g., Ora) offering analyses, observations, and suggestions based on your data.

1.2. Warning — Stellia Is Not a Medical Service

IMPORTANT: Stellia is a tool for well-being, self-reflection, and communication. It does not constitute:

  • a medical device within the meaning of Regulation (EU) 2017/745;
  • a mental health service, psychotherapy, or diagnostic tool;
  • a substitute for the advice of a healthcare professional.

In particular:

  • No content in the Application (AI messages, analyses, suggestions, visualizations, notifications, etc.) should be interpreted as a diagnosis, medical recommendation, or psychotherapy;
  • The AI features (Ora) generate automated content that may be imperfect, incomplete, or unsuitable for your personal situation;
  • Stellia does not replace the advice of a healthcare professional, nor appropriate medical or psychological care.

1.3. In Case of Distress or Emergency

If you are experiencing significant distress, suicidal thoughts, or any other concerning symptoms, contact a healthcare professional or emergency services immediately.

Stellia may display help links or phone numbers, but does not handle real-time emergencies and cannot detect crisis situations.
