Privacy Policy

Last updated: 20 September 2026

This policy explains how Reactia handles your information. The app is provided by Volkan Günay (Vomcore). Contact: hello@vomcore.com.

Short version

We run no server. The chemistry, the experiments and the table are inside the app, and what you do on the bench never leaves your device. No account is required and the app works with no internet connection. The only network traffic the app can produce is the purchase check described under Payments, and opening these legal pages in your browser.

What is stored on your device

• Your discovery log: which reagent pairs you have already found on the bench.
• Whether Reactia Pro is active, so the app does not have to ask the store on every launch.

None of this is transmitted to us or to anyone else. Deleting the app deletes it.

Permissions

The app requests no permissions. It does not use the camera, photos, location, contacts, microphone or notifications. If a permission prompt ever appears, that is a bug — please tell us.

Chemistry data

The reactions, the experiments and the periodic table are bundled inside the app. Nothing is fetched, and no search or reagent choice is sent anywhere.

Payments

Reactia Pro is a subscription or a one-time lifetime purchase, and either one is handled by the App Store. We never see or store your payment details. Whether Pro is active is verified through RevenueCat, Inc. using an anonymous identifier that contains no name, email address or phone number.

Analytics and advertising

There are no ads, no advertising identifier and no third-party ad network. There is no analytics SDK: we do not know which reactions you run or which elements you look up.

Use of AI

No AI service is involved. Every reaction shown is a stored record written and checked by a human; the app cannot invent one, and nothing you enter is sent to a model.

Children

Reactia is suitable for school-age users and does not knowingly collect data from anyone, at any age. It asks for no name, no email address and no sign-in.

Your rights

Because your data lives only on your device, you erase it in the app — Settings has a Reset discovery log control — or by removing the app. Questions: hello@vomcore.com.

Changes

If this policy changes, the date above changes. Significant changes are announced in the app.
