Frequently Asked Questions

How does the Pomodoro Technique improve focus?
The Pomodoro Technique trains your brain to resist interruptions by working in dedicated 25-minute intervals followed by 5-minute restorative breaks. This prevents cognitive fatigue and maintains high working memory capacity.
What are Ultradian Rhythms and the 52/17 Rule?
Ultradian rhythms are natural 90-minute human biological cycles of peak alertness followed by 20 minutes of restorative rest. The 52/17 rule is an empirical discovery from DeskTime tracking showing the top 10% most productive knowledge workers work dedicatedly for 52 minutes followed by a 17-minute complete mental break.
How does the Workday Finish Time projector work?
The planner sums your target focus cycles, short breaks, and long breaks, then adds this total duration to your current start time to forecast exactly when your workday sessions will finish.
Does the timer require an internet connection?
No. The timer uses the browser native Web Audio API oscillator to synthesize gentle chime notifications locally. It operates 100% offline with zero external network downloads.
What should I do during short and long breaks?
Short breaks (5 mins) should involve physical movement, stretching, resting your eyes, or drinking water away from screens. Long breaks (15-30 mins) can include a short walk, meditation, or a nutritious snack.
Is my session data sent to any remote server?
No. All session logs, timers, and calculations run strictly client-side in your local browser sandbox with zero telemetry or cookies.
