How Insights Work Without Storing Health Data

We generate insights like "You focus better after good sleep" without keeping your actual sleep data. Here's how:

  1. When you start a session, your health data is categorized (e.g., "good sleep" vs "low sleep")
  2. We update aggregate statistics: "Sessions with good sleep have X average focus"
  3. The raw values (7.5 hours, quality 4/5) are discarded immediately
  4. Only the pattern ("good sleep = better focus") is stored

A Note on Session Notes

While your session notes are encrypted and unreadable to us, we recommend avoiding highly sensitive information (passwords, financial details, etc.) in your notes. The encryption protects your privacy, but good data hygiene is always smart.
