Privacy Policy
This Privacy Policy describes how Zenppon ("we") collects, uses and protects information when you use the QuotiDei application (the "App"). By using the App you accept the practices described in this document.
1. Data Controller
Zenppon, based in Argentina, is the controller of the personal data collected through the App. For any privacy inquiry you can write to us at zenppon33@gmail.com.
2. What Data We Collect
The App works without the need to create an account. We only collect personal data when you choose to sign in or use social features:
| Data | When it is collected | Purpose |
|---|---|---|
| Google account identifier, email address, name and profile picture | Only if you sign in with Google (optional) | Identify you and sync your progress across devices |
| Player name, picture, selected theme | When playing while signed in | Show your profile and personalize the experience |
| Game progress (streaks, statistics, scores) | When playing while signed in | Rankings, achievements and competitive streaks |
| Friend code, opponents' names and pictures | When using social/multiplayer mode | Connect with friends and manage matches |
| The text you send through the feedback form | If you send us feedback | Improve the App and reply to you if appropriate |
| Advertising identifier and device data | On mobile versions, when showing ads | Display advertising (see section 6) |
| App usage events (which minigame and theme you played, the outcome and the mode) and an installation identifier generated by Firebase | Always, even without signing in | Aggregated statistics to understand which parts of the App are used (see section 6) |
| Error reports: technical details of the failure, device model and operating system version | If the App crashes or fails | Detect and fix errors |
We do not collect precise location data or contacts.
3. How We Use the Data
- Provide and maintain the App's features (progress, rankings, social mode).
- Sync your progress across devices when you sign in.
- Prevent cheating through server-side result validation.
- Display advertising to keep the App free.
- Respond to your inquiries or feedback reports.
- Measure App usage in aggregate to decide what to improve.
- Detect and fix errors and crashes.
4. Legal Basis for Processing (GDPR)
For users in the European Economic Area, we process your data on the following bases: performance of the service you request (playing, syncing), your consent (sign-in, personalized advertising) and our legitimate interest (security and fraud prevention). You can withdraw your consent at any time.
5. Who We Share Data With
We do not sell your personal data. We only share it with providers that enable us to operate the App:
- Google Firebase (Authentication, Firestore, Cloud Functions) — authentication, progress storage and server logic. See Firebase privacy and Google's Privacy Policy.
- Google AdMob — advertising on mobile versions. See how AdMob uses data.
- Firebase Analytics — aggregated usage statistics, to understand which parts of the App are used and which are not. The events we send do not include your name, your email or your account identifier: only which minigame and theme were played, the outcome and the mode.
- Firebase Crashlytics — crash and error reports so we can fix them. They include the technical detail of the error, the device model and the operating system version.
6. Advertising, Analytics and Identifiers
Mobile versions show ads through Google AdMob to keep the App free. Advertising may use a device advertising identifier.
- iOS: before enabling tracking we will ask for your permission via the App Tracking Transparency (ATT) dialog. If you decline, you will see non-personalized ads.
- EU/EEA and UK users: we show a consent form (Google UMP) so you can choose between personalized or non-personalized advertising.
Usage analytics. We use Firebase Analytics to understand, in aggregate, which parts of the App are used: how many people finish the initial walkthrough, which minigames and themes are played most, and where a session is abandoned. It helps us decide what to improve.
- The events do not include data that identifies you: no name, no email, no account identifier. Only catalog ids (minigame, theme, difficulty, mode), outcomes and counters.
- Firebase generates its own installation identifier, which is different from the advertising identifier and is not used for advertising. It is deleted when the App is uninstalled.
- We do not use this data for personalized advertising and we do not combine it with the information AdMob receives.
Error reports. We use Firebase Crashlytics to detect crashes and failures. The report contains the technical detail of the error, the device model and the operating system version — nothing you write and nothing from your profile.
7. Data Retention
We keep your progress and account data while you keep the App or your account active. If you delete your account from the App or from the web, deletion is immediate; if you request it by email, we process the request within 30 days. Section 9 details what is deleted, what is retained and why.
8. Your Rights
Depending on your jurisdiction (GDPR, CCPA and Argentina's Law 25.326, among others) you may exercise the rights of access, rectification, erasure, objection and portability of your data. We do not sell personal information in the CCPA sense. To exercise them, write to us at zenppon33@gmail.com.
9. Account and Data Deletion
You can erase your match history, your streaks and your achievements — on this device and in your connected Google account — while keeping your account, from Settings → Danger Zone → Reset Stats and Achievements within the App. To delete your account entirely, use any of these three routes:
- From the App: Settings → Danger Zone → Delete account and data. Deletion is immediate and does not require contacting us.
- From the web, without installing the App: quotidei.web.app/delete-account.en.html.
- By email: write to zenppon33@gmail.com from the address linked to your account. We process requests within 30 days.
What gets deleted: your account identifier, email, display name, progress, inventory, statistics, your friends and your friend code, and your entries in leaderboards and duels. Your authentication account is removed at the end of the process, so you will not be able to sign in again.
What is kept: matches against other players remain in your opponent's history, without your name or photo, because they are also that person's record; any match still in progress is closed in your opponent's favour. Your suggestions and content reports are kept without the link to your account, because they describe the puzzle and not you. Diagnostics and analytics data (Crashlytics, Analytics) do not identify you and are unaffected. We only retain minimal records where a legal obligation requires it.
Deletion is irreversible: progress cannot be recovered afterwards.
10. Children's Privacy
The App is intended for a general audience over 13 years old and is not directed at children. We do not knowingly collect data from children under 13. If you believe a minor provided us with data, contact us so we can delete it.
11. International Transfers
Our providers (Google) may process data on servers located outside your country. These transfers are carried out under the protection mechanisms those providers implement in accordance with applicable regulations.
12. Changes to This Policy
We may update this Privacy Policy. We will post the current version at this same address with its update date. Continued use of the App constitutes acceptance of the changes.
