By default, Truple will alert when incognito mode is used. However, the screenshots Truple captures from incognito mode on Android will be black, unless you adjust specific settings (instructions shown below).
Incognito mode alerts on android
The Truple app analyzes each screenshot to determine if incognito or private mode was used. If it detects that incognito/private browsing was used, it will immediately send a tamper email out to all report recipients including the website that was being visited while incognito mode was used. Below you can see an example of what the email looks like.

Newer versions of Chrome have a setting that you can adjust so that incognito mode no longer blocks screenshots from being captured as well. If you follow the instructions below, incognito mode will be captured as normal and alerts won't be sent when incognito mode is used.

False positive incognito alerts on Android
Truple needs to analyze screenshots in order to identify incognito/private browser use. It looks for a specific pattern within the screenshot--primarily a mostly black screen. There are times when phones can "glitch" and produce a screenshot that looks identical to an incognito/private browser screenshot, even though incognito wasn't being used. This will result in false positive alerts being sent out. From what we've seen this happens rarely when it does happen, and we'd prefer to deal with the false positive alerts (which contain the website being visited within them when possible) instead of not alerting at all. We'll continue to look for ways to improve the accuracy, but for now false positives, while rare, can occur. When they do, have report recipients check the website being visited and as long as it's clean then there's nothing to worry about.
