I finally gave in and installed Truecaller as I wanted to avoid all those annoying telemarketers. I registered with my phone number, enabled blocking of “spammers” and disabled features I didn’t feel like I needed.

The next day I received my first notification reminding me something about Truecaller. The day after that again.

As standard Android notifications were not enough, there was couple of custom popup’s after I received text messages.

That made ma look to the actual preference file of the app. It contains records such as:

    <boolean name="truecaller.alarm.notification.TYPE_1DAY.fired" value="true" />
    <boolean name="truecaller.alarm.notification.TYPE_2DAYS_NEW.fired" value="true" />
    <boolean name="truecaller.alarm.notification.TYPE_2DAYS_UPGRADED.fired" value="true" />
    <boolean name="truecaller.alarm.notification.TYPE_5DAYS.fired" value="true" />
    <boolean name="truecaller.alarm.notification.TYPE_7DAYS.fired" value="true" />
    <boolean name="truecaller.alarm.notification.TYPE_15DAYS.fired" value="false" />
    <boolean name="truecaller.alarm.notification.TYPE_20DAYS.fired" value="false" />
    <boolean name="truecaller.alarm.notification.TYPE_RESCHEDULE.fired" value="false" />
    <boolean name="truecaller.alarm.notification.TYPE_UPDATE_SPAM.fired" value="false" />
    <long name="truecaller.alarm.notification.TYPE_1DAY.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_2DAYS_NEW.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_2DAYS_UPGRADED.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_5DAYS.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_7DAYS.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_15DAYS.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_20DAYS.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_RESCHEDULE.set" value="0" />
    <long name="truecaller.alarm.notification.TYPE_UPDATE_SPAM.set" value="1466500401780" />

So Truecaller will spam you 1, 2, 5, 7, 15, and 20 days after installation with various reminders to keep you using the app, installing other Truecaller apps, start using widgets or liking/sharing.

This is just too much for me. I only have 50 apps installed on my phone but if every app pushed notifications like that, I would go crazy.

In the end, it seems like Truecaller is (just) using www.muzutozvednout.cz anyway (at least for some numbers here in Czech Republic).

Ok, Truecaller offers “Upgrade to Professional”, but it’s monthly subscription (29 CZK = 1.2 USD per month) and it says “Remove all ads” but doesn’t specify what marketing experiments will I still be part of. I don’t care if I “Get the Pro badge on your profile”.
