Streakly is a local-first desktop habit tracker for people tired of renting their own checkmarks. Habitify charges $5/month forever — $180 over 3 years — to store your streaks in their cloud. Streakly is $15 once, no account, no telemetry, no network calls at all: your entire history is one human-readable JSON file on your machine.

The streak engine is the star — it's actually fair:

• Weekday-only habits survive the weekend; off-days never break a streak

• "N times per week" habits count weekly quotas across week boundaries

• Vacation mode freezes streaks instead of killing them

• Numeric goals ("8 glasses of water") track partial progress through the day

• Today doesn't break your streak just because it isn't done yet

• GitHub-style year heatmap per habit plus an all-habits month view

• Native OS reminders, notes per day, drag-to-reorder, 30/90/365-day stats

• One-click JSON and CSV export for backup and spreadsheets

Runs as a Windows desktop app — fully offline, zero setup.
