Mercury collects 2 data types tied to your identity but declares no tracking.

Did Mercury ask for something?

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

Tap a prompt to compare it with the label.
Not on the label

Location is not on Mercury'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.

Not on the label

User Content is not on Mercury'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.

Not on the label

Contacts is not on Mercury'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.

Not declared on the label

Mercury declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.

Not on the label

Health & Fitness is not on Mercury'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 Mercury collects, explained

Usage DataLinked 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 Mercury's label means for you

Mercury's label has 2 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.

Mercury declares no tracking, which means the developer says it does not combine your data with other companies' data for advertising or sell it to data brokers. The data linked to you — usage data and diagnostics — is still tied to your identity, typically through an account, and is covered by the developer's privacy policy and retention rules.

None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.

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. Mercury lists 2 data types, fewer than 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 Mercury

iOS 18 and later

Lock Mercury behind Face ID

  1. Find Mercury 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. Mercury now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Mercury 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 Mercury 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.
