Cairn - 차곡차곡

Cairn (차곡차곡) is a calm, anonymous-first todo app — every core feature works without an account. Like the small stones stacked into a cairn on a quiet trail, line up today's tasks one by one with clarity.

■ Core features

• Anonymous by default: no sign-up, no transmission. All data stays on your device.
• Inline markers: type @, #, !, * to set date, time, importance, and repeat in one line. e.g. "@tomorrow #3pm meeting", "*every-monday run".
• Two-way swipe: left for reschedule / favorite / repeat. Right for duplicate / move group / delete.
• Groups and color labels: organize by work, personal, fitness — at a glance.
• Notifications with quiet hours: push reminders that auto-defer to the next morning during quiet hours.
• Stats dashboard: weekly / monthly / yearly completion, 14-day sparkline, average completion time.
• Backup & restore: JSON / CSV / Markdown export and import. Move devices safely.
• Dark mode and three themes (Tica, Tally, Nudge).
• English / Korean auto-detected.

■ Tracks

• Anonymous (default): full core, on-device only.
• Pro: ad-free — one-time purchase, yours forever.

■ What we don't collect

No location, contacts, photos, microphone, camera, or health data. In anonymous mode, not a single byte leaves your device.
