Where is the data stored?

Qualia (questions and answers and other settings) are securely stored in a private MySQL database at Heroku. Like most web apps, Qualia uses SSL to encrypt data in transit.

The questions and answers pass through either OpenAI servers (where they are retained for 30 days for US compliance purposes, but are not used for training any LLM) or Perplexity servers (where they are not stored at all).
