LEGAL & PRIVACY

Transparency. Security. Trust.

At Nair Engineering, privacy is a human right. We minimize data collection and prioritize On-Device Processing.

  • Payment: Processed by Apple/Stripe. We do not store credit card details.
  • Automatic: Anonymous crash reports, device type (e.g., iPhone model).

3. Where Your Data Lives

  • On-Device: Significant AI inference occurs locally on your Neural Engine/GPU.
