Headache PalMigraine Tracker

Privacy policy

Last updated

Short version: your headache logs stay on your iPhone. There is no account, no ads and no tracking. Kip's AI chat only sends data after you say yes, and you can turn it off at any time.

Headache Pal is made by an independent developer (“we”, “us”). We built it to collect as little as possible. This policy explains exactly what the app stores, where, and what leaves your phone. If anything is unclear, write to info.stilak@gmail.com.

Which app this covers

There is no Android, iPad or web version of the app.

The short list

What the app stores on your iPhone

When you use Headache Pal, the app saves what you enter: headache date and time, pain level, where it hurts, how it feels, symptoms, triggers, medicines and whether they helped, notes, and your daily “No headache” check-ins. It also saves your settings, your own triggers and medicines, your answers from the first-run questions (such as your goals and known triggers), and a cached daily tip. Your chat with Kip is not saved: it is cleared when you start a new chat or close the app.

This data is stored in the app’s private storage on your iPhone. A shared App Group lets the Headache Pal widget on your Home Screen or Lock Screen read it, still on your device. The app does not use iCloud or any other cloud sync. If you back up your iPhone with iCloud or a computer, Apple’s normal device backup may include app data, under Apple’s own terms.

Chat with Kip (AI)

Kip’s chat uses an AI model to reply. Before Kip’s first reply (in the chat or the “Give me a tip for today” button), the app asks for your permission and explains what will be sent. If you say no, nothing is sent and the rest of the app works as usual.

If you say yes, then for each chat:

Kip is not a doctor. Replies can be wrong and are not medical advice.

Apple Health

Connecting Apple Health is optional (Settings > Apple Health). If you turn it on:

Health data is never sent to the AI, never shared with third parties for advertising, and never used for marketing. You can change Health access at any time in the iOS Settings app under Privacy & Security > Health > Migraine Tracker.

Purchases

Headache Pal Pro is sold through Apple’s App Store. Apple handles payment; we never see your card details. We use RevenueCat to check whether your subscription is active. RevenueCat receives an anonymous app user ID (not your name or email), purchase and receipt information, and basic device information such as iOS version, app version and language. See RevenueCat’s privacy policy.

What we do not collect

The app asks for only two permissions, and both are optional: Apple Health (to save headaches and read sleep) and notifications (for the evening reminder). It never asks for the camera, microphone, photos, contacts or location.

Reminders and widgets

The evening check-in reminder is a local notification scheduled on your iPhone. Widgets read your data from the shared App Group on your device. Neither sends data to us.

Exports and the doctor report

When you export your data (PDF of your logs, doctor report PDF, CSV or JSON), the file is created on your iPhone. It leaves your device only if you share it yourself through the iOS share sheet, for example by email to your doctor. Once shared, the receiving app or person controls that copy.

When you contact us

If you email us, we receive your email address and whatever you write, and use them only to reply. When you use Settings > Report a problem, the email the app opens already includes your iPhone model, iOS version and app version, so we can help faster; you can delete these lines before sending. We do not add you to any mailing list, and we delete support emails when they are no longer needed. Ask us to delete yours at any time.

This website

headachepal.com is a static website hosted by Cloudflare. It sets no cookies and runs no advertising or third-party analytics scripts. To see which pages help people find the app, we count page views, App Store button taps and how far articles are read, without cookies or any personal data: each visit only adds one to a daily total for that page, together with the country, the device type (iPhone, Android or other) and the kind of site the visit came from (for example a search engine). No IP address, identifier or browsing history is stored, so no visitor can be recognized or followed. Your browser keeps only that source type, and only until you close the tab. Like any web host, Cloudflare processes technical data such as your IP address to deliver the pages and protect against attacks. Links to the App Store go to Apple, which has its own privacy policy.

Keeping and deleting your data

Your data stays on your iPhone until you delete it. To delete your headaches, open Settings > Delete all headaches in the app. This also removes them from Apple Health if you connected it. To remove everything else (check-ins, settings and your own lists), delete the app. Because we do not hold your logs on a server, there is nothing for us to delete on our side. For data held by OpenAI, AIProxy or RevenueCat as described above, contact us and we will help with your request.

Your rights

Depending on where you live (for example under the GDPR in the EU and UK, or state laws in the US such as the CCPA), you may have rights to access, correct, delete or move your personal data, and to object to or limit its use. Most of your data is only on your device, where you control it directly. For anything else, email info.stilak@gmail.com. You can also complain to your local data protection authority.

Where the law requires a legal basis: we process chat data with your consent (you can withdraw it in Settings > Share with AI), and purchase data to provide the subscription you bought.

International transfers

OpenAI, AIProxy and RevenueCat may process data in the United States or other countries. They use safeguards required by law for such transfers.

Children

Headache Pal is not intended for children under 13, and we do not knowingly collect data from them. If you think a child has used Kip’s chat, contact us.

Medical disclaimer

Headache Pal is a diary and wellbeing tool. It is not a medical device and does not diagnose, treat or prevent any condition. Always talk to a doctor about your health.

Changes

If we change how the app handles information, we will update this page and the date at the top before the change takes effect.
