Common questions
How does AlertBox detect payments?
AlertBox reads incoming SMS and matches them against known bank/UPI templates, then announces the amount aloud.
Is AlertBox free?
Yes. It is free and ad-supported. Premium removes ads.
Is my SMS data sent to Trei?
No. SMS parsing happens entirely on-device. Nothing is uploaded.
Which banks and UPI apps are supported?
Most major Indian banks and UPI apps are supported out of the box. Custom templates can be added.
Does it drain my battery?
AlertBox is event-driven — it only activates when a matching SMS arrives, so idle battery use is negligible.
