Data Collection & Usage

A. Interaction Data

To provide architectural insights, Lattice processes specific technical data:

  • Diagram Image: We capture a temporary snapshot of your current Excalidraw canvas.
  • Technical Context: We gather relevant text or code snippets you verify to improve evaluation accuracy.
  • Processing: All analysis is performed by the Google Gemini API. Data is never stored on Lattice servers.

B. Storage & Security

  • API Keys: Your Gemini API key is stored locally in your browser's encrypted storage.
  • Encryption: Data transmitted to Google is secured via HTTPS/TLS 1.3 encryption.

Data Protection

We do not sell, rent, or share your data with third parties except for the necessary transmission to Google for AI analysis.

  • No Tracking: Lattice does not use trackers, analytics, or background telemetry.
  • Anonymity: Evaluations are independent and not linked to a Lattice user account.
