HOW IT WORKS
Caffeine Tracker uses scientific data to calculate how much caffeine remains in your bloodstream. The extension adjusts calculations based on your profile:

• Thresholds adjust to your body weight
• Sleep threshold: 2 mg/kg (when sleep may be affected)
• Maximum threshold: 5.7 mg/kg (recommended daily limit)
PRIVACY
All data stays on your device. Nothing is sent to external servers.
