User Content is not on Certifient Secure Email'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.

Certifient Secure Email 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 Certifient Secure Email'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 Certifient Secure Email collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| Browsing HistorySensitiveUsed to track youLinked to you | Websites and other content you viewed that is not part of the app. | In browsers, use private tabs and clear history; Settings › Apps › Safari has Safari's own controls. |
| Contact InfoUsed to track youLinked to youNot linked 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. |
| Usage DataUsed to track youNot linked 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. |
What Certifient Secure Email's label means for you
Certifient Secure Email's label has 3 types under “Data Used to Track You”, 2 types under “Data Linked to You”, 2 types 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 contact info, browsing history, usage data from Certifient Secure Email 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 browsing history. Browsing history is a detailed record of interests. It is expected from browsers and content blockers and unusual elsewhere.
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. Certifient Secure Email lists 3 data types, about the same as 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.

Lock Certifient Secure Email behind Face ID
- Find Certifient Secure Email 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. Certifient Secure Email now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Certifient Secure Email 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 Certifient Secure Email 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.
