Privacy policy
In short: the app collects nothing about you. Below is why, and what applies if you write to me.
Summary
The Periodic table - Elementa app does not collect, store or send any personal data.
How the app works
All element data is bundled with the app. It works without an internet connection and does not talk to any server. It uses no analytics, ads, tracking or third-party tools, and requires no account or sign-in.
Data processed by Apple
If you have allowed your device to share analytics with app developers, Apple may make anonymous aggregated usage statistics and crash reports available to me. This data does not identify you, and you can turn sharing off at any time in Settings → Privacy & Security → Analytics & Improvements. Apple processes it under its own privacy policy.
Children
The app is intended for children too. Since it collects no personal data, it collects none from children either.
If you write to me
If you contact me by e-mail, I use your address and message only to reply to you and keep the message only as long as that requires. I, Miroslav Tourek, am the controller of this data. You have the right to access, correct and erase it, and to lodge a complaint with the Czech Office for Personal Data Protection (uoou.gov.cz).

Changes
If a future version of the app starts handling data differently, I will update this policy before that version is released. The current version is always at this address.
