ADR 0006 — The Streak is derived; Reminders are rescheduled, not repeating
Status: Accepted (2026-10-29)
Streak
The Streak, its Freezes and the calendar are computed from scratch from the end times of all complete
Sessions (both Modes) every time they are shown (Streak.compute). Nothing about the Streak is stored:
a Freeze is earned, held and spent deterministically by walking the days from the first Streak Day to
today. The Grace Hour is applied while assigning Sessions to Streak Days, in time order, so the rule
"counts for yesterday unless yesterday is already done" is stable.
A few years of daily Sessions is a few thousand rows, which is cheap to walk.
Reminders
Android cannot skip a repeating notification on days that are already done, so instead of repeating alarms the app schedules one-off notifications for the next 14 days and replaces them whenever something changes: on app start, after every saved Session and after a Reminder setting changes. A day that is done gets none. If the app is not opened for two weeks, Reminders stop; that is acceptable for a gentle nudge.
They use inexact scheduling (inexactAllowWhileIdle), which needs no exact-alarm permission but lets
Android deliver up to about an hour late. Permission to post notifications is asked for after the
first complete Session, or from Settings.
