Frequently Asked Questions (FAQ)
What can I log in the headache diary?
For each headache you can record the date and time, the type (migraine, tension, cluster, sinus or other), pain intensity from 1 to 10, duration in minutes, possible triggers such as stress, lack of sleep, dehydration, skipped meal, screen time or caffeine, any medication taken, and free notes.
What statistics does the diary show?
It shows the total number of entries, your average pain intensity, the most common trigger across all entries, and how many entries you made this month. Newest entries appear first in the list.
Is my headache data private?
Yes. All entries stay in your browser only and are never sent to a server. Clearing your browser data will permanently remove them.
Can I delete an entry?
Yes. Each entry has its own Delete button, and the statistics update automatically after a deletion.
Can the diary diagnose my headaches?
No. This is a personal diary, not medical advice, and it cannot diagnose anything. If your headaches are severe, sudden, new, or getting worse, please see a doctor.
