Privacy Policy & Data Deletion
Last updated: 5 September 2026
Zolva is a puzzle app (Sudoku, KenKen and Nonogram). This page explains what
data the app handles and how to have it deleted. It covers the Android app
published on Google Play under the package com.jeanpierre.zolva.
| Data | Why | When |
|---|---|---|
| Name and email address from your Google account | To identify your account so your progress can follow you between devices | Only if you choose to sign in with Google |
| User ID and friend code | To run leaderboards and the friends list | Always |
| Game progress — saved puzzles, statistics, best times, streaks, settings | So your progress is not lost when you reinstall or change phone | Always |
| Advertising ID | To show ads, via Google AdMob | Always, unless you have ads removed |
What other players can see: the name you choose and your completion times appear on the daily leaderboards. Nothing else is visible to anyone.
What we never do: we do not sell your data, build advertising profiles of our own, or share your information with anyone beyond the services named here (Google Firebase for storage and authentication, Google AdMob for ads, and Google Play for purchases).
Payments are handled entirely by Google Play. We never see or store your card or payment details.
Storage and security: data is stored in Google Firebase and is sent over encrypted (HTTPS) connections. Access is restricted so that only you can read or write your own data.
Children: Zolva is not directed at children under 13 and we do not knowingly collect data from them.
You can delete everything yourself, from inside the app, at any time:
What is deleted: your account, saved games, statistics, best times, streaks, daily-challenge history, leaderboard scores, friend code, friends list, and your entry in other players' friends lists — on your device and on our servers. This is permanent and cannot be undone.
Retention: nothing is kept after deletion. Ordinary server backups may retain copies for up to 30 days before they expire automatically.
No longer have the app installed? Email the address below from the Google account you signed in with, asking for deletion, and we will remove your data within 30 days.
