Hush

Terms of Use

Last updated: 7 November 2026

These terms apply when you download or use Hush: Migraine Tracker & Diary ("Hush"), an app from Itworked Systems, a company registered in Türkiye, free to download with optional paid Pro. By using it, you agree to them. If you downloaded the app from Apple's App Store, Apple's standard license agreement applies as well.

A diary, not medical advice

• Hush helps you keep a personal record of headaches and migraine attacks and shows counts and summaries of what you logged. It does not diagnose, treat or monitor any disease, it is not a medical device, and it does not replace a doctor.
• Words like "possible trigger" describe what you chose to note. The app does not decide what brings on your attacks or what helps.
• Never start, stop or change a medication because of something in the app. If your headaches change, get worse, or come with new symptoms, contact a doctor. In an emergency, call your local emergency number.

Using the app

We give you a personal, non-commercial right to use the app on devices you own or control. Please don't copy, resell or redistribute it. We may change or improve features with updates.

Hush Pro

• Logging, history, the calendar, 30-day stats, the 30-day text summary and backups are free. Hush Pro is optional and adds the PDF doctor report for any period, stats for 3, 6 and 12 months, trigger, symptom and medication insights, sleep from Apple Health on iPhone, and a Face ID or fingerprint lock.
• Pro is sold as a yearly subscription (with a free trial where offered), a monthly subscription, or a one-time lifetime purchase. Prices are shown in the app before you buy and are charged by Apple or Google.
• Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before it ends. You can manage or cancel them in your App Store or Google Play account settings. If you cancel during a free trial, you are not charged. Any unused part of a free trial ends when you buy a subscription.
• Refunds are handled by Apple or Google under their rules. Use Restore purchases in Settings to unlock Pro on a new phone with the same store account.

Your diary is yours

• Everything you log stays on your phone and belongs to you. We have no copy.
• Because there is no cloud backup, you are responsible for keeping your own copies. Use Export backup in Settings now and then, and keep the file somewhere safe. If you delete the app or lose your phone without a backup, your diary cannot be recovered.
• Check reports before you share them. They show what was logged, and they are only as complete as your diary.
