## What is Circa?

Build a calmer bedtime routine and understand the patterns behind your sleep.

Circa combines a practical circadian schedule with private sleep insights from Apple Health. Plan the habits that shape your day, reduce digital distractions before bed, and follow your sleep trends without sending sensitive health data to external servers.

YOUR DAILY RHYTHM
• Create a personalized wake-up, morning light, meal, wind-down, and bedtime routine
• See your current phase and what comes next at a glance
• Receive optional reminders and Live Activities at the right time

PROTECT YOUR WIND-DOWN
• Choose distracting apps, categories, or websites with Screen Time
• Apply optional boundaries during wind-down and after waking
• Keep your selections private through Apple’s Family Controls framework

PRIVATE SLEEP INSIGHTS
• Turn sleep records stored in Apple Health into clear duration and bedtime trends
• Follow resting heart-rate patterns from a compatible wearable
• Explore interactive weekly and monthly charts

CALMER DISCOVERY
• Browse a focused collection of products for darkness, noise, comfort, and waking
• Open product pages securely in an in-app Safari view
• Affiliate links are clearly disclosed and never affect your price

PRIVACY BY DESIGN
Your Apple Health values and Screen Time selections are processed on your device. They are never sent to Mixpanel, Amazon, or advertising platforms. Circa uses limited analytics only when a Discover product link is opened.

Circa is a general wellbeing tool and is not a medical device. It does not diagnose, treat, cure, or prevent any condition.
