Plan bedtime or wake-up time, allow time to fall asleep and build a weekly schedule with private calendar and summary exports.
Use the tool
Choose units, measurements or a session preset. Review the supported scope beside the controls.
Adjust the plan and review the visual result. For a timer, select Start; Pause, Reset and Next remain available where applicable.
Save a private summary, schedule or log if offered. Nothing is uploaded or automatically saved.
Understand the method and limits
Clock-time planning, not sleep measurement or fixed 90-minute cycle prediction. Most adults need at least seven hours of sleep. Sleep-onset time is a user assumption. Calendar events use floating local times; daylight-saving changes can alter elapsed duration. No alarm or guaranteed background reminder.
Keep your information private
Inputs and logs stay in page memory. No account, upload, health-data analytics, browser storage or medical-record synchronization. Leaving or refreshing the page can clear the session; explicitly downloaded files contain your information. Exports are local PNG/PDF summaries, CSV schedules or logs, and a sleep calendar where offered. These tools are for general planning and estimates, not diagnosis or individualized treatment.
Try the workflow
Keep your original documents and review the output. You can also browse all guides or contact Team Hypomnema.
