Privacy Policy — Inhead

Last updated: 6 October 2026

Inhead keeps your headache diary on your own device, and in your own iCloud only if you turn that on. It has no server of its own and no account with us.

The headaches, symptoms, treatments, notes and settings you enter are stored in the app’s database on your iPhone or iPad. Syncing is off until you turn on Sync with iCloud in Inhead’s Settings; then, if you are signed in to iCloud, that database is also kept in your own private iCloud storage, so the same diary appears on your other devices. That storage is yours: it sits in your Apple Account, it counts against your iCloud space, and it is governed by Apple’s iCloud terms and privacy policy. What Inhead puts there is end-to-end encrypted, with keys only your devices hold, so neither Apple nor we can read it. There is no Inhead server, no Inhead account, and no way for us or anyone else to reach your records. You can stop the syncing at any time by turning Sync with iCloud off in Inhead’s Settings, or iCloud off for Inhead in the iOS Settings app, and the diary stays on the device.

Inhead contains no analytics, no crash reporting and no advertising, and it does not track you across other apps or websites. The two open-source components it builds on — Apple’s swift-numerics and the SVGView drawing library — draw and calculate; neither collects anything and neither talks to a network. Nothing you record is used to build a profile of you or shared with any third party.

The only data that ever leaves the app by your hand is the doctor’s report you choose to export: it is handed to the iOS share sheet, and where it goes from there is your choice. Deleting the app removes it and its local database from that device; the copy in your iCloud is yours to manage, in the iOS Settings app under your Apple Account. If Inhead ever cannot open your diary and you choose Start over, the old diary is kept on the device, set aside, until you delete Inhead.

If you use Siri or Shortcuts with Inhead, Apple processes your request under its own terms and your Siri settings. Inhead gives the system the names of its built-in treatments in advance, so Siri can recognise them; the name of a treatment you added yourself reaches Siri only when you say it or choose it. What you log is saved on your device.
