Support

Write to support@molvenda.com. Tell us which app, which phone, and what happened; a screenshot helps. We usually answer within a few days.

I bought the full version on another phone

Open the app, tap Unlock, then Restore purchase. Make sure the phone uses the same Google account you bought with.

I want a refund

Purchases go through Google Play, so refunds do too. Within 48 hours you can usually request one yourself on Google Play's refund page. After that, write to us and we will look at it.

I found a mistake in an answer

The answer keys are checked by software when each app is built, but please tell us if something looks wrong. Name the app, the level and the molecule, and we will check it and fix it in the next update.

Does the app need the internet?

No. Everything works offline. Only buying or restoring the unlock needs a connection, since that goes through Google Play.

Do you collect data?

No. See the privacy policy.
