1. Contact

Email [email protected]. We aim to reply within 2 business days. There is no live chat, no phone line, and no support portal — just that inbox, read by the same people who build the app.

2. Troubleshooting — HealthKit

• Nothing shows up after granting access. HealthKit only returns data your iPhone actually has. If your Health app is empty for the date range you picked, the export will be empty too. Open Health → Browse → Summary and then Health → Sharing → Data Access & Devices to confirm your Apple Watch or phone is writing the sources you expect. Pick those sources there first, then re-run the export.
• The permission sheet never appeared. iOS only shows the HealthKit prompt once. If you dismissed it or denied by mistake, fix it from Settings → Privacy & Security → Health → Health Export Kit and toggle on the categories you want the app to read. The app can also re-open that screen for you: Settings → Review permissions.
• Revoking access.Use the same iOS screen (Settings → Privacy & Security → Health → Health Export Kit) to turn categories off, individually or all at once. The app re-checks on every launch and will only read what you currently allow.

3. Troubleshooting — Exporting

• The export is empty. Most often this means there is simply no HealthKit data in the window you chose. Widen the date range, or pick a range you know has data (for example the last 7 days). Metrics you did not tick will also not appear — that is by design.
• The export looks too short. By default the app writes a compact summary so it fits comfortably into an LLM context window. If you want every raw sample, turn on Verbose export on the Format screen before running the export.
• The export contains a metric I deselected. It shouldn't. As of v1.0 the per-metric filter is applied before the file is written. If you see a metric in the file that you had unticked, that is a bug — please email us with the steps and we'll fix it.

4. Troubleshooting — Sharing & files

• Where exports live. Open the Files app and go to On My iPhone → Health Export Kit → Exports. Every export you have run is there, oldest at the bottom. You can delete, rename, or share them from Files just like any other document.
• Re-share an old export.Open the app's History screen, tap any past export, and choose Re-share. The iOS share sheet opens with that file attached — send it to AirDrop, Messages, Mail, a notes app, an LLM client, or anywhere else.
• Files persist across launches. Nothing is auto-deleted. Exports stay on disk until you remove them from Files, clear history in Settings, or delete the app. Clearing history only removes the in-app log; the files themselves stay until you delete them in the Files app.

5. Reporting a bug

Email [email protected] with the following, so we can reproduce it quickly:

• iOS version (Settings → General → About → Software Version).
• Device model (same screen, Model Name).
• App version (in the app: Settings → About).
• Steps to reproduce — what you tapped, what you expected, what happened instead.

Please do not attach your export file unless we explicitly ask for it. Exports can contain sensitive health and location data and we would rather not receive it by default. A screenshot of the app or a short description is almost always enough.

6. Feature requests

Same inbox: [email protected]. Concrete asks ("I want ECG waveforms in JSON", "I want to exclude sources from brand X") are more useful than general wishes and are more likely to actually ship. We read everything.

7. Data privacy

Health Export Kit is on-device only — no accounts, no servers, no analytics. The full details are on the privacy policy.

8. App Store review questions
