Privacy policy

Last updated: 13 November 2026. This policy covers every Molvenda app.

In short: our apps do not collect, store or share any personal data. They have no account, no ads and no analytics, and they work without an internet connection.

On your device

Your settings, your progress and whether you have unlocked the full version are saved only on your phone. They are removed when you uninstall the app. We cannot see them.

Purchases

The one-time unlock is sold through Google Play. The app asks Google Play whether you have bought it, so the purchase follows your Google account to a new phone. Google handles the payment under its own privacy policy. We do not see your payment details. For bookkeeping and refunds we receive the order information that Google Play gives every developer, such as an order number, the date and the country.

Permissions

The apps only ask for network access and Google Play Billing, which are needed to buy and check the unlock. They do not use your camera, location, contacts or files.

Medical information

MedChem Trainer teaches chemistry using real medicines. It is not medical advice and gives no guidance on dosing or treatment.

Children

The apps are educational tools for students. They collect no data from anyone, including children.

Changes

If this policy changes, the new version will be published on this page with a new date.
