Did Temp Mail Pro ask for something?
Pick the permission prompt you saw. We compare it with what Temp Mail Pro's developer declared.
Location is not on Temp Mail Pro'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.
User Content is not on Temp Mail Pro'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.
Contacts is not on Temp Mail Pro'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.
Temp Mail Pro 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.
Health & Fitness is not on Temp Mail Pro'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.

|---|---|---|

What Temp Mail Pro's label means for you
Temp Mail Pro's label has 1 type under “Data Used to Track You”, 1 type under “Data Not 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 identifiers from Temp Mail Pro 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.
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.
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. Temp Mail Pro lists 1 data type, fewer than the average of 2.9 for this group.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.

Lock Temp Mail Pro behind Face ID
- Find Temp Mail Pro on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Temp Mail Pro now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Temp Mail Pro has a passcode of its own. It does not change what the app sends to its developer.

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 Temp Mail Pro 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.
