Habits

A per-user habit tracker with a configurable target per period. The deterministic streak calculator reports current, longest, and 30-day rolling totals, and habitsAtRisk() flags anything whose streak will break today unless you hit its target.

• Daily or multi-day targets (targetPerPeriod, periodDays)
• Current streak, longest streak, and 30-day completion sparkline data
• An at-risk endpoint surfaces habits one check-in away from breaking
• Per-user scope, so teammates never see each other's habits

• Streak math is UTC-day based. If you travel across timezones, check-ins near midnight can surprise you.
• Archiving a habit preserves its history but hides it from active lists.

1. 1Create a habit with a target and period (for example, 1/1 daily, or 3/7 three times a week).
2. 2Check in each time you complete it. Check-ins are idempotent per day.
3. 3Review the at-risk list every evening to protect your streaks.

Can I track habits across a team?

Not today. Habits are per-user by design so no one feels monitored. Shared team rituals live in Cycles and Goals.

Why did my check-in land on the wrong day?

Streaks are calculated on UTC days. A check-in close to midnight, particularly while travelling, can therefore fall either side of the boundary from where you expect it.

If I stop a habit, have I lost the record of it?

No. Archiving hides a habit from the active list and preserves its history, so the streak you built remains readable even though the habit is no longer being tracked.
