As a security consultant, I regularly use Telemetry Deck because it perfectly combines data protection and user-friendliness. The setup is quick – everything runs in a few minutes – and the software immediately provides clear, understandable data. I particularly appreciate that data protection is not only considered here but consistently implemented. The data preparation is clear and understandable – ideal, even for less technical users. In short: Telemetry Deck is a data protection-friendly, straightforward solution that I wholeheartedly recommend.

Privacy focused, very easy to integrate into the app, ease of use, price is affordable. Originally, I considered Mixpanel as an alternative, but TelemetryDeck won.

TelemetryDeck is great for guaranteeing privacy of your users, being GDPR compliant and keeping your app’s Privacy Details in the App Store not scary. It’s easy to setup and won’t result in concerning additions to your privacy policy either. It comes with useful built-in charts and dashboards tailor-made for mobile apps, including device type breakdowns, OS versions, user language vs device language, daily active users, etc. The user retention chart is also great for understanding what percentage returns to using the app. It’s really nice that you get all of this without having to even add your own metrics to the app. For custom analytics, you can define your own signals and duration signals. Duration signals track the time events take, and are specially useful in my case to assess the app’s performance and the time people spend in screens on average. Other services may include more complex concepts like sessions for tracking higher level activities, but TBH I don't miss them, and some of the limitations are probably related to being privacy focused. You don't get as fine-grained tracking, but I value the privacy I get as a result. The price has been good for me, as an indie developer.
