Privacy Is the Foundation

We built ByteThirst to be private by default, not private by promise.

What we NEVER collect

  • Your conversations (prompts or responses)
  • What topics you discuss
  • Exact timestamps (only the date)
  • URLs you visit
  • Your identity (free tier)
  • Browser fingerprint

What we do collect (locally only)

  • Number of queries per day (by platform)
  • Estimated token counts
  • Model type (e.g., GPT-4o, Claude Sonnet)
  • Date (no time)

All data stays on your device in chrome.storage.local. Free users make zero network calls. Even premium users only transmit email and subscription status — never usage data.
