Version 1.1 — Effective: 2 March 2026
Health Exporter is developed by Spookwerk, a sole proprietorship (eenmanszaak) based in the Netherlands. This policy explains how the app handles your data. The short version: your data stays on your device. Spookwerk does not access, cannot access, and will not access your data.
Health Exporter does not collect, transmit, or store any personal data on external servers. The app contains no analytics, no tracking, no telemetry, no advertising, no crash reporting, and no network calls. It does not collect device identifiers, usage data, or any other information. It does not require an internet connection or a user account.
The app reads health data from Apple HealthKit with your explicit permission. It can access up to 187 data types across 14 categories: Activity & Fitness, Mobility, Running, Cycling, Heart, Respiratory, Body Measurements, Vitals & Lab, Nutrition, Sleep, Hearing & Environment, Reproductive Health, Symptoms, and Workouts. This includes sensitive data such as electrocardiogram (ECG) recordings with voltage waveforms.
The app is read-only — it never writes, modifies, or deletes any data in Apple Health.
This data is processed entirely on your device to generate export files (JSON and CSV). Specifically:
Your health data is never used for advertising, marketing, data mining, or any purpose other than generating the export files you requested. This complies with Apple's HealthKit guidelines.
Health data is classified as a special category of personal data under the EU General Data Protection Regulation (GDPR). The lawful basis for processing your health data is your explicit consent (Article 9(2)(a)), which you provide through the iOS Health authorization dialog. No data is processed until you grant this permission.
All exported data is stored locally on your device by default, in compliance with Apple's guidelines for health data. If you choose a cloud-based export folder, the data is transferred to that provider under their terms and privacy policy.
You are in full control of your exported files. You can view, share, or delete them at any time through the iOS Files app. Uninstalling Health Exporter removes all app data from your device, including export history and settings. Exported files in a custom folder you selected are not affected by uninstallation.
Exported files remain on your device (or in your chosen export folder) until you delete them. There is no automatic expiration or scheduled deletion. Spookwerk retains no copy of any data — all data exists solely on your device and under your control.
You have full control over your data:
Under the GDPR, you also have the following rights:
Health Exporter offers a one-time in-app purchase to unlock premium features. Purchases are processed entirely by Apple through StoreKit and require an internet connection. Spookwerk does not receive or store any payment information.
The app uses no third-party SDKs, libraries, or services. All functionality is built using Apple's native frameworks. There is no server-side component — Spookwerk operates no servers and no backend for this app.
Health Exporter is a data export tool, not directed at children under 13. It does not provide medical advice, diagnosis, or treatment recommendations. The exported data reflects what is stored in Apple Health and should not be used as a substitute for professional medical judgment. Exported values reflect device sensor measurements, which have inherent accuracy limitations. Young users in particular should consult a parent or healthcare professional before interpreting health data.
If this policy changes, the updated version will be posted here with a new effective date and version number. Material changes will be noted in the app's update notes.
