How Deck works
A calm companion for the details that matter.
Deck brings your private history, calendar and guidance into one careful experience across web, iPhone and Android.
Add an observation
Choose the date, time and event location, then review what you entered.
See the calendar clearly
Deck keeps each calculation reason independent and shows whether it applies by Day or Night.
Use your trusted devices
Your Deck account works everywhere. Encrypted-history access is approved separately on trusted devices.
Privacy without complication
Apple, Google or email signs you into your account. Trusted-device encryption protects sensitive history. An optional local app lock protects a particular phone. These are separate safeguards, each doing one clear job.
