Privacy Policy
Last updated: October 14, 2026 (version 1.2)
4Migraine is made by Robert Poetzsch (robspace.de), who is responsible for this app within the meaning of the GDPR. Contact: support@robspace.de. The postal address is in the legal notice (Impressum) on this website.
In short. Everything you record in 4Migraine stays on your device. The app makes no network requests of its own: there is no 4Migraine server, no user account, no location access, no analytics, no advertising, no tracking and no third-party SDKs. The developer receives none of your data.
What you enter and where it is stored. Migraine entries (start and end time, intensity, where the head hurts, symptoms, medications and notes with time stamps), your symptom and medication lists and your app settings are stored only on your iPhone/iPad, in the app's private storage. Older or imported entries may also contain weather values; the app does not fetch weather data. While a migraine is being logged, the running entry is kept separately on the device so that it survives a crash.
Report details. If you fill in the form for a PDF report, the name, date of birth and comment you type are saved on the device so you do not have to enter them again. They appear only in reports you create yourself. "Reset All Data" deletes them together with your entries and a running migraine.
Reminders. If you switch on the check-in reminder while logging a migraine, the app asks for permission to show notifications and schedules them on the device. No push server is involved. Reminders stop when the migraine is ended or when you switch the reminder off.
Backups, export and reports. About once a week, when you open the app and there are entries, 4Migraine writes a backup file into its own Documents folder on the device and keeps the last seven; you can also create, restore and delete backups manually. JSON exports and PDF reports are created on the device and leave it only if you share them yourself via the iOS share sheet (for example by AirDrop, mail or Files). Who receives them is your decision; the developer has no access. A PDF report contains your entries and, if you entered them, your name, date of birth and comment. After sharing, the app deletes its temporary copy of the file. Importing reads only the file you pick.
iCloud and device backups. 4Migraine has no iCloud sync. Like any app data, its data — including the backup files and the report details — is part of your iCloud or computer backup of the device if you have turned that on. This is an Apple function that you control in iOS Settings.
Links. Links in the app (medical sources, the community pages on GitHub, robspace.de, e-mail) open in your browser or mail app only when you tap them. The app itself sends nothing to these sites; the respective provider's privacy policy applies there.
Health data. Information about migraines, symptoms and medications is health data under Art. 9 GDPR. It is processed only on your device under your control and is never transmitted to the developer or to third parties by the app.
Your control and your rights. In the app, Log → Settings (gear icon) → Data lets you back up, restore, export or reset your data. "Reset All Data" removes entries, report details and a running migraine; backup files are deleted separately under Backup & Restore. Deleting the app removes all its data from the device; copies in device backups and files you shared remain under your control. You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR). Because the app sends the developer no data about you, there is nothing the developer could disclose, correct or delete; questions are still welcome at support@robspace.de. You have the right to lodge a complaint with a data protection supervisory authority, for example the Hessian Commissioner for Data Protection and Freedom of Information (HBDI).
Not a medical device. 4Migraine is a diary and information app. It is not a medical device and does not provide diagnosis or treatment. Always consult a qualified healthcare professional.
This website. This website is hosted by Hetzner Online GmbH on a server in a data centre in Falkenstein, Germany. When you open a page, the web server automatically logs your IP address, the date and time, the requested page or file, the HTTP status, the number of bytes transferred, the referring page (referrer) and your browser’s user agent. These logs are used solely to operate and secure the website; the legal basis is Art. 6(1)(f) GDPR (legitimate interest in secure, stable operation). They are deleted automatically after 14 days at the latest, are not analysed and are not passed on unless required by law.
The website sets no cookies, uses no analytics or tracking and embeds no content from third parties. Only your language choice is kept in your browser’s local storage, and not for tracking. Fonts are served from this server; no connection is made to Google Fonts or other font services.
Changes. If the app's handling of data changes, this policy is updated and the date above changes.
