Polymail collects 5 data types tied to your identity but declares no tracking.

Did Polymail ask for something?

Pick the permission prompt you saw. We compare it with what Polymail'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 Polymail'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

Polymail 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 Polymail'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

Polymail 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 Polymail'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 Polymail collects, explained

Data typeWhat it coversWhere to limit it
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.
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 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 Polymail's label means for you

Polymail's label has 5 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.

Polymail 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 — user content, contact info, identifiers, 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.

The items that deserve the most attention are user content. This is the content you actually care about. Where it is stored, who can read it and how it is backed up matters more than any other line on the label.

Email apps see every message and contact. Third-party mail clients may route mail through their own servers to offer features like push or AI summaries. Check whether the client connects to your provider directly or stores your mail on its servers.

Among the 141 secure email apps in our snapshot with a label, 28% declare tracking, 60% collect data linked to you and 23% say they collect nothing. Polymail lists 5 data types, more than the average of 2.9 for this group.

Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

On your iPhone

Settings to check for Polymail

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

Cross-app tracking

Does Polymail track you?

iOS 18 and later

Lock Polymail behind Face ID

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

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