Privacy Policy

Welcome to the Lexical Lattice app for Android!

As a developer, I take privacy very seriously. I know how frustrating it is when apps collect your data without your knowledge.

Data collected by the app

I hereby state, to the best of my knowledge and belief, that I have not programmed this app to collect any personally identifiable information. All data created by you (the user) — including your game stats, token balance, win streak, and puzzle history — is stored locally on your device only, and can be erased by clearing the app's data or uninstalling it. No analytics software is present in the app.

However, Lexical Lattice integrates Google Play Billing (for in-app token purchases), which may collect certain data independently. Please refer to the relevant section below for details.

Third-party services

Google Play Billing

In-app purchases (token packs) are handled entirely by the Google Play Billing system. Any payment or transaction data you provide is processed by Google and is subject to Google's Terms of Service and Privacy Policy. The app itself does not store or transmit your payment information.
