This Privacy Policy describes how Chem Lab (“the App”, “we”, “us”) handles information when you use our mobile application on Android. The App is published by Vasa Serafin.
Offline lab. The bundled reaction table, picks, and settings stay on the device. We do not operate a chemistry server. Chem Lab is a reaction card, not a university course. Classroom table only. Not mixing advice.
Summary
- We do not sell your personal information.
- Offline-first. The reaction table runs on your device without our servers.
- No cloud AI or machine learning.
- Local data stays local. Uninstalling removes app storage.
Information we process
- Reaction table and settings — stored on-device. Not uploaded to us.
- Purchase status — Google Play confirms No Ads (INAPP
com.vasaserafin.chemlab.noads or SUBS com.vasaserafin.chemlab.noadssub). We store a local entitlement flag only.
- Advertising (Lite only) — Google AdMob may collect device identifiers and ad interaction data per Google’s Privacy Policy. A banner may show on lab and settings; a full-screen ad may show on first open and after hard-coded react / next-card counts. UMP consent is requested before ads.
What we do not do
- We do not sell personal information.
- We do not upload your reaction picks to our servers.
- We do not require a cloud account.
- We do not operate a university course, mixing-advice service, or lab-safety program.
Legal bases (EEA/UK)
- Contract — providing the reaction table and ads-free features you request.
- Consent — personalized ads in Lite where required (Google UMP).
Retention and deletion
Uninstalling the App or clearing its storage removes local settings. Ad partners and the Play Store may retain purchase or ad data under their own policies.
Your rights
Depending on your region you may have rights to access, correct, delete, or port your data. Local deletion is typically achieved by uninstalling or clearing app data. Contact vasa_serafin@hotmail.com.
California residents: we do not “sell” or “share” personal information as defined by the CCPA/CPRA.
