Questions

Short answers.

Read the batch code guide
What does it cost?

Free to download. The bear reads your code on a small server, and the ads pay for its keep, so the app stays free for you. If you'd rather have it quiet, Premium or Ad-Free Forever removes them.

Where is my history kept?

On your phone, and it stays there. There is no account.

How accurate is the date?

When the bear knows a brand's system, the date comes straight from the code. Shelf life is an estimate, so trust your eyes and nose too.

Which brands are covered?

More than 500. If a code can't be dated, the bear says so. See how the common ones work.

What data do you collect?

Usage and crash reports through Firebase, and ads through Google AdMob, with your consent where the law requires it. Purchases go through the store. See the privacy policy.
