LexiSort — Privacy Policy
1. Who we are
LexiSort is a word-sorting game for Android that teaches English words. It is published by Private Enterprise "VRK KRONOS" (ПРИВАТНЕ ПІДПРИЄМСТВО "ВРК КРОНОС"), registered in Ukraine ("we", "us"). We are the controller of the data described in this policy. Contact: lexisort@vrkkronos.com.
2. In short
You do not need an account, and we never ask for your name or email address. Your progress stays on your phone. The game sends gameplay statistics, without your name or email, to our own server; you can turn this off in Settings. Ads are shown by Google AdMob, and only when you choose to watch one. We do not sell your data.
3. Data stored on your phone
Your English level, the words you have met and learned, your review schedule, stars, badges, daily goal and streak, your settings and, if you enter one, a school code are stored only on your phone. We cannot see them.
If Android backup is on, Android may copy this data to your Google account backup and restore it on a new phone. Google provides this backup under its own terms; you control it in your phone's settings.
To delete this data, use Settings → "Reset all progress" in the game, or uninstall the app. More: how to delete your data.
4. Gameplay statistics
To understand how the game is played and to improve it, the app sends gameplay events to our own server (api.vrkkronos.com). Examples: the app was opened; a level was started, won, failed or replayed, with the moves, stars and wrong guesses; which words were shown; hints, undos and ads used; badges earned; settings changed; which Premium features you tapped and your answer.
Each event carries a random ID created when you install the game. It is not linked to your name, email, Google account or advertising ID. Events also carry the app version, the menu and meaning language, your English level, the date and time, and, if you have one, your school code or the partner link you installed from (section 6).
Like every internet connection, sending the events shows your IP address to our server. We use it only to deliver the data and to protect the server from abuse, and we do not store it with the statistics. Server logs that contain IP addresses are deleted after 14 days.
Statistics are kept for up to 25 months and then deleted automatically.
You can turn statistics off at any time in Settings → "Send statistics". Events not yet sent are then deleted from your phone. Clearing the app's data or reinstalling the game creates a new random ID.
Legal basis (EEA, UK): our legitimate interest in improving the game (GDPR Article 6(1)(f)). You can object at any time by turning statistics off.
5. Ads (Google AdMob)
LexiSort shows ads only when you choose to watch one, for example for an extra undo, a hint or more moves. The ads come from Google AdMob and are limited to content suitable for teenagers.
AdMob may collect and use your device's advertising ID, your IP address, information about your device and the app, and how you interact with ads, to show and measure ads, to prevent fraud and, if you agree, to personalise ads.
In the European Economic Area, the United Kingdom and Switzerland, the game asks for your choice with Google's consent form when it first starts. You can change your choice at any time in Settings → "Ad privacy options". You can also reset or delete your advertising ID in your phone's settings (Settings → Google → Ads, or Settings → Privacy → Ads).
How Google uses this data: policies.google.com/technologies/partner-sites. Google's privacy policy: policies.google.com/privacy.
6. Partner schools
Schools and teachers can give players a school code (Settings → "School code") or a partner link to the game on Google Play. If you install from a partner link, Google Play tells the app the link's tag. The code or tag is added to your gameplay statistics so that we can count players per partner. It does not tell us who you are. We may tell a partner school how many players use its code and how much they play, as totals only, never per player.
7. Who processes data for us

| Google (Play, Android backup) | Delivering the app; backup if you turn it on | Under Google's own terms |
We do not sell or rent your data. Google may process data in other countries under its own safeguards.
8. What we do not collect
We do not collect your name, email address, phone number, contacts, photos, precise location or microphone recordings. The game has no accounts, chat or social features.
9. How long we keep data

10. Your rights
Depending on where you live (including under the EU GDPR and the Law of Ukraine "On Personal Data Protection"), you can ask to access or delete your data and object to its use, and you can complain to your data protection authority (in Spain: AEPD, www.aepd.es; in Ukraine: the Ukrainian Parliament Commissioner for Human Rights).
Because we do not know who you are, we can find your statistics only by the random install ID shown in Settings. To ask for access or deletion, write to lexisort@vrkkronos.com with that ID. We answer within 30 days.
11. Children
LexiSort is meant for players aged 13 and over. It is not directed at children under 13, and we do not knowingly collect their data. If you believe a child under 13 has used the game and data was collected, contact us and we will delete it.
12. Security
Data is sent over encrypted connections (HTTPS), and access to our server is limited to people who need it.
13. Changes to this policy
We will publish any change on this page with a new effective date, and tell you in the game before an important change, such as a new kind of data.
