Tracks you

Grey's developer reports using usage data to track you across other companies' apps and websites.

Did Grey ask for something?

Pick the permission prompt you saw. We compare it with what Grey's developer declared.

It asked me for access to…
Tap a prompt to compare it with the label.
Not on the label

Location is not on Grey's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.

Matches the label

Grey lists User Content on its label, linked to you. Choose Limited Access and pick only the photos you want to share.

Not on the label

Contacts is not on Grey's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.

Expected — and you can decline

Grey declares data used to track you, so expect the “Allow to track?” prompt. Tap Ask App Not to Track; the app must keep working without it.

Not on the label

Health & Fitness is not on Grey's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.

A permission is what the app can reach on your iPhone; the label is what the developer says leaves it. They answer different questions.

Line by line

What Grey collects, explained

Data typeWhat it coversWhere to limit it
Financial InfoSensitiveLinked to you Card numbers, bank details, credit scores, salary, income, assets or debts. Pay with Apple Pay where offered so the app never sees your card number, and turn on the app's own login lock.
User ContentSensitiveLinked to you Messages, photos, videos, audio recordings, documents and support chats you create or upload. Settings › Privacy & Security › Photos: choose Limited Access or None; review Microphone and Files access too.
Contact InfoLinked to you Your name, email address, phone number or postal address. Use Sign in with Apple with Hide My Email where offered, and check the app's account and marketing preferences.
PurchasesLinked to you What you have bought or tend to buy. Review in-app marketing settings; subscriptions are listed in Settings › [your name] › Subscriptions.
IdentifiersLinked to you An account ID, screen name, customer number or a device-level ID such as the advertising identifier. Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted.
Usage DataUsed to track youLinked to you What you tap, open and view inside the app, plus which ads you have seen. There is no single iOS switch. Look for an analytics or personalised-ads toggle in the app's own settings.
DiagnosticsLinked to you Crash logs, launch times, hang rates and energy use. Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate.
Reading the label

What Grey's label means for you

Grey's label has 1 type under “Data Used to Track You”, 7 types under “Data Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.

Tracking is the declaration that most separates apps. It means usage data from Grey can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.

The items that deserve the most attention are financial info and user content. Financial data is high-value to criminals and is often regulated. Expect it in banking and budgeting apps; question it elsewhere.

Banking apps must collect identity and financial data to work; that is expected. Tracking declarations and third-party advertising SDKs are what to compare. Turn on the app's own biometric login and transaction alerts, and download banking apps only from the bank's own developer account.

Among the 196 banking apps in our snapshot with a label, 17% declare tracking, 91% collect data linked to you and 3% say they collect nothing. Grey lists 7 data types, about the same as the average of 6.6 for this group.

Finance apps need identity and financial data to function. Expect Contact Info and Financial Info; compare apps on tracking and third-party advertising instead.

On your iPhone

Settings to check for Grey

  1. 1

    Tracking

    Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.

  2. 2

    Photos

    Settings › Privacy & Security › Photos. Limited Access lets you pick exactly which pictures the app can see; Add Photos Only lets it save without reading your library.

  3. 3

    Sign-in

    When creating an account, Sign in with Apple can give the app a relay address from Hide My Email instead of your real one.

  4. 4

    Lock the app

    On iOS 18 and later, touch and hold the icon and choose Require Face ID. Anyone who picks up your unlocked phone then needs your face, fingerprint or passcode to open it.

  5. 5

    Notifications

    Settings › Notifications › Grey › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

Cross-app tracking

Does Grey track you?

Yes — 1 data type

Usage data. Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker.

iOS 18 and later

Lock Grey behind Face ID

  1. Find Grey on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. Grey now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Grey has a passcode of its own. It does not change what the app sends to its developer.

Read with care

What the label cannot tell you

  • A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Grey sends.
  • It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
  • Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
  • Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
  • Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.

The question to ask Grey's developer: Is this app published by my bank's verified developer account?
