CheckIn - Solopreneur Tracker

CheckIn is a private, on-device attendance and presence tracker for solopreneurs, freelancers, and remote workers who want real, office-style work discipline — without a boss, a login, or a server.

Start a session with a single check-in and CheckIn keeps a live timer running in a notification until you check out. Every check-in and check-out is confirmed by an on-device presence check, so your recorded hours reflect time you were genuinely present.

HOW IT WORKS
• Check in to start a work session; check out to end it. Your net time is the sum of your completed intervals for the day.
• Each check-in and check-out is verified by an on-device face check (offline). If it cannot be completed, the app falls back to your device biometric or screen lock.
• While you're checked in, a periodic presence reminder asks you to re-verify. Time between the reminder and your response is paused, so idle time doesn't inflate your hours.
• Set a daily target. Each day is graded against the target in effect that day: meet it and you're present; fall short and a half-day or full-day leave is recorded.
• A rolling leave deficit accumulates from your start date, giving an honest running picture of your discipline over time.

PRIVATE BY DESIGN
• 100% on-device. There is no account and no server.
• The app ships without the internet permission, so nothing about you can be uploaded, tracked, or sold.
• The camera is used only for the presence check. Each frame is analysed on your device and deleted immediately — no image is ever stored, shown, or shared.
• No ads. No analytics. No third-party data collection.
• Your attendance history stays in a local database on your phone. Export it to CSV whenever you like — that copy is yours.

WHO IT'S FOR
CheckIn suits solopreneurs, freelancers, consultants, students, and anyone working without external oversight who wants to build and measure a consistent daily work habit. It treats every day the same — the discipline is yours to keep.

CheckIn is a self-discipline tool, not a substitute for any employer or legal time-keeping system.
