It is a fair question to ask, and an important one. Here is a plain, honest answer.
MigraineMe only knows two kinds of things about you:
- What you choose to type, tap, or speak into the app.
- What you choose to switch on or connect (your watch, your sleep app, your weather location, phone signals like screen time, and so on).
That is it. The app does not look at anything you have not given it.
Things you typed or logged yourself
When you log a migraine, MigraineMe stores:
- The time the migraine started and ended.
- How bad it was (the 0 to 10 number).
- Any triggers, medicines, reliefs, or symptoms you tapped on.
- Any notes you wrote.
- The pain location on the head diagram, if you tapped on it.
You can see all of this in the Journal tab at any time.
Things from your AI setup
When you first signed up, MigraineMe asked you a set of questions (the AI setup). Your answers are stored too. You can see a summary on the Profile screen under "Your Migraine Profile".
Things from connected apps and devices
If you chose to connect a watch, a fitness band, a sleep app, or a food app, MigraineMe stores the readings those send across. Things like:
- Sleep hours and quality.
- Step count and heart rate.
- Meals and ingredients.
- Period information, if you connected a tracker.
You can see and turn off any of these connections by tapping the gear icon in the top-left of the screen, then Connections (to disconnect a wearable) or Data and Notifications (to switch individual metrics off).
Things from your phone, if you switched them on
Some optional signals come from the phone itself, and each one only works if you allowed it in the Data and Notifications screen and granted the matching phone permission:
- Screen time, including late-night screen time. Full screen time is Android only. iPhone estimates late-night screen time only.
- Ambient noise level samples. This is a loudness number only. The app does not record or store any audio.
- Phone habits such as brightness and volume. Android also counts how often you unlock the phone.
- Calendar events, so the evening check-in can offer them for one-tap tagging.
Every one of these has its own switch in the Data and Notifications screen, and all of them can be off.
Your current location (only for the weather)
If you allowed location access, MigraineMe checks roughly where you are every so often, so the weather card can show you the pressure, temperature, and humidity for your actual area. Weather changes are a real trigger for many people. The app uses an approximate position from Wi-Fi and mobile networks, not GPS.
These positions are saved with the date in your account, so past weather can be matched to past migraines. They are deleted when you delete your account. We do not share your location. The app does not ask for permission to use your location in the background, and you can switch location off any time.
What MigraineMe does not know about you
To be very clear, MigraineMe does not look at:
- Your contacts.
- Your photos (other than a profile picture you picked, or a meal photo you took in the app).
- Your texts or messages.
- Your call log.
- Your other apps.
- Your bank or payment details. Apple or Google handles all of that.
- Your browser history.
Where to see everything
Two screens are useful here:
- Journal tab: every migraine, trigger, medicine, and note you have logged.
- Insights tab: what the app has learned from your data, summarised in charts.
If something there does not look right, you can edit or delete it. You are always in charge of your own data.
