Using Dusk
Dusk: Migraine Tracker (“Dusk”, “the app”) is developed by Asaduzzaman (“we”, “the developer”). By downloading or using Dusk you agree to these terms. Your use of the app is also governed by Apple’s Licensed Application End User License Agreement (Standard EULA), which applies to all apps distributed through the App Store.
Not medical advice
Dusk is a tracking tool, not a medical device. It does not diagnose, treat, cure, or prevent any condition, and nothing in the app — including trigger patterns, correlations, weather alerts, and reports — is medical advice. Insights are based only on the data you log and may be incomplete or wrong. Always consult a qualified health professional about your migraines, your medications, and any decisions about your care. Never delay seeking medical help because of something the app showed you.
Dusk Pro: subscriptions & lifetime purchase
Core logging is free. Dusk Pro is an optional paid upgrade, offered as an auto-renewing subscription (monthly or yearly) or a one-time lifetime purchase:
- Payment is charged to your Apple account at confirmation of purchase.
- Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends, at the price shown at purchase.
- You can manage or cancel subscriptions anytime in your device’s Settings → your name → Subscriptions. Deleting the app does not cancel a subscription.
- The lifetime option is a single one-time payment, not a subscription, and does not renew.
- Purchases are tied to your Apple ID and can be restored on your other devices via Restore Purchases in the app.
- Refunds are handled by Apple under App Store policies — request one at reportaproblem.apple.com.
Prices may change for new purchases; an active subscription’s price will not change without notice as provided by the App Store. Current pricing is always shown in the app before you buy.
Your data
Your health data stays on your device and in your private iCloud — see the Privacy Policy for the full picture. You are responsible for keeping your device and iCloud account secure, and for maintaining backups (iCloud sync, if enabled, serves this purpose). The app is provided without a warranty that data loss can never occur; export your data regularly if it matters to you.
Acceptable use
Don’t reverse-engineer, resell, or misuse the app, and don’t use it in any way that violates the law or Apple’s terms. The app, its design, and its content are the developer’s intellectual property.
Warranty & liability
Dusk is provided “as is”, without warranties of any kind, to the maximum extent permitted by law. To the same extent, the developer is not liable for indirect or consequential damages arising from your use of the app. Nothing in these terms limits liability that cannot be limited by law. Where the Standard EULA and these terms overlap, the Standard EULA governs your license to the app.
Third-party services
Weather data is provided by Apple Weather. iCloud sync and Apple Health are provided by Apple under your Apple account terms.
Changes
We may update these terms as the app evolves; material changes will be reflected on this page with a new date. Continued use after a change means you accept the updated terms.
