4 Decision Content and Sensitive Information

We recognize that the decisions you create in Decidia may touch on deeply personal matters — including health conditions, financial situations, family circumstances, or other sensitive topics. A user might create a decision such as "Choose an oncologist for upcoming treatment" or "Decide whether to change careers," which could reveal sensitive personal information.

Our commitments regarding Decision Content:

  • Private by default. Your decisions are visible only to you.
  • We do not read your decisions. Decidia employees and contractors do not access or review your Decision Content except: (a) at your explicit request when seeking technical support, or (b) when required by a valid legal obligation.
  • No profiling. We do not use Decision Content to build profiles, serve advertising, draw inferences about you, or make automated decisions about you.
  • No sharing. Decision Content is never disclosed to third parties, except to our database infrastructure provider (Supabase) solely for the purpose of storing it securely and returning it to you.
  • No AI training. Decision Content is not used to train, fine-tune, or benchmark any machine learning or AI systems, now or in the future.
