Frequently Asked Questions
Common questions and answers about the Sleep Quality Tracker.
How does the Sleep Quality Tracker work?
Enter the date, the time you went to bed, the time you woke up, and rate your sleep quality from 1 (Poor) to 5 (Excellent). Click 'Generate Report' and the tool instantly calculates your total sleep duration and displays a personalised sleep summary.
How many hours of sleep do I need?
Most adults need 7–9 hours of sleep per night according to the National Sleep Foundation. Teenagers need 8–10 hours, and school-age children need 9–11 hours. Consistently sleeping less than 7 hours is linked to increased health risks.
What does the sleep quality rating mean?
The 1–5 quality scale reflects how rested and refreshed you felt upon waking: 1 = Poor (exhausted), 2 = Fair (somewhat tired), 3 = Good (reasonably rested), 4 = Very Good (well-rested), 5 = Excellent (fully refreshed and energised).
What if I went to bed before midnight and woke up after midnight?
The tracker automatically handles overnight (midnight-crossing) sleep. It detects when your wake time is earlier than your bed time and adds 24 hours to calculate the correct duration.
Is my sleep data stored or shared?
No. All calculations happen entirely in your browser. No data is uploaded, stored, or shared with any server. Your sleep information stays completely private.
