What My Phone Knows for iPhone privacy policy

Last updated September 23, 2026

Short version: this version of the app never goes online. Everything it reads stays on your iPhone, there is no account and no server, and it collects nothing. That is what its App Store privacy label says too: Data Not Collected.

What this covers

This is the policy for What My Phone Knows on iPhone, made by Pettigrew Lab LLC. On the App Store its bundle ID is com.pettigrewlab.wmpk.

The web site has its own policy, because a web page and an app do different things and collect different things. If you came here from a browser, that is the one you want.

What My Phone Knows, the app’s page

It never goes online

This version opens no network connections of its own. No ads, no analytics, no crash reporting, and no server of ours for anything to go to.

Two things in the app are links: this policy and the contact email. Tapping one hands you to Safari or Mail, and nothing is sent unless you send it yourself.

What the app reads, and where it stays

The first screen shows what your iPhone tells any app without asking: the model, the iOS version, language, region and currency, time zone, screen size, battery, whether you are on wifi or cellular, a few accessibility settings, and the ID iOS gives every app from the same developer.

It reads them to show them to you, which is the point of the app. None of it is stored and none of it leaves the phone.

Your App Privacy Report

Your apps reads a file you export yourself, from Settings, then Privacy & Security, then App Privacy Report, and share or open in the app. It is read where it sits, not copied. If iOS makes a copy of it on the way in, the app deletes that copy as soon as it has read it.

The report the app builds from it is held in memory and is gone when you close the app. Nothing from the file, not an app name and not a domain, goes anywhere.

The tracker list it matches against, compiled by Exodus Privacy, ships inside the app. Nothing is fetched to run a match.

What the app saves on your iPhone

One date, and only if you tap “I’ve turned it on”: the day you said you started App Privacy Report, so the app can tell you when a week is up.

“I haven’t actually turned it on” clears it, and so does deleting the app. That is the whole list.

The reminder

If you tap “Remind me in a week”, the app asks iOS for permission to send notifications, then schedules one notification on the phone for the morning a week after that date. It is the only notification the app ever sends, and it is set up on your iPhone, not sent from anywhere.

Cancel it in the app, or switch notifications off for the app in Settings.

What the app asks permission for

Nothing when you open it. The only permission it can ask for is notifications, and only when you tap for the reminder.

No location, no contacts, no photos, no camera, no microphone, and no tracking. The app does not ask for them, so it cannot get them.

Tracking and the advertising ID

The app does not track you and never asks to. It does not read the advertising ID at all.

The Ads screen explains what an ad request carries, using this phone’s own values so the example is real, and sends none of it. There is no ad in this version.

If a later version shows an ad, this page says so, and so does the App Store privacy label, before that version ships.

What we do not do with any of it

We do not sell your personal information. There is nothing to sell: none of it reaches us.

Children

The app is written for adults, and we do not knowingly collect anything from a child. In this version we do not collect anything from anyone.

Deleting your data

There is no account, so there is nothing on our side to delete. Deleting the app removes the one date it saved, and any reminder with it.

If you email us

Then we have your email address and whatever you wrote, and we keep it as long as it takes to answer you. It does not go on a list.

If this changes

The date at the top changes with it. If a future version sends anything anywhere, this page says so before that version ships, rather than after somebody finds out.
