Contact info, browsing history and usage data.
Yes. Certifient Secure Email's developer declares contact info, browsing history and usage data as data used to track you — data that can be combined with other companies' data for targeted ads or ad measurement, or shared with data brokers. On iPhone you can refuse: tap Ask App Not to Track, or switch off tracking requests for every app in Settings.
What “tracking” means on an iPhone
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. It is narrower than “collecting data”: an app can collect a lot without tracking you, and a small app can track you with a single advertising SDK.
Since iOS 14.5, App Tracking Transparency requires every app to ask before it accesses your device's advertising identifier or otherwise tracks you. The App Store label is where the developer declares which of its data is used that way. Certifient Secure Email declares 3 data types, so expect the “Allow Certifient Secure Email to track your activity across other companies' apps and websites?” prompt.
The data Certifient Secure Email uses to track you
Contact Info
Your name, email address, phone number or postal address. Contact details identify you directly and are what marketing lists and account recovery rely on.
Browsing History
Websites and other content you viewed that is not part of the app. Browsing history is a detailed record of interests. It is expected from browsers and content blockers and unusual elsewhere.
Usage Data
What you tap, open and view inside the app, plus which ads you have seen. Product analytics show developers which features are used. The same records can also feed advertising when an app declares tracking.
How to stop Certifient Secure Email from tracking you
- When Certifient Secure Email shows the tracking prompt, tap Ask App Not to Track.
- Already said yes? Open Settings › Privacy & Security › Tracking and switch off the toggle next to Certifient Secure Email.
- To refuse every app in one go, switch off Allow Apps to Request to Track on the same screen. Apps then cannot ask, and are treated as if you declined.
- For Apple's own ads in the App Store, News and Stocks, see Settings › Privacy & Security › Apple Advertising and turn off Personalised Ads.
- Inside Certifient Secure Email, look for an analytics or personalised-ads switch in its own settings; it covers data the iOS switch does not.
