Privacy Policy — Daniel Quiz

1. Who we are

Developer: Anas — contact: AAA78JO@gmail.com

2. Data we collect

No sign-in is required. If you play as a guest, your scores stay on your device and do not appear in public rankings. The app still creates an anonymous guest account (no name or email) and sends to Firebase a random identifier (UID), basic usage statistics (last seen, play time, ads watched, app version and language, approximate country) and any multiplayer results — for app functionality, fraud prevention and analytics.

If you choose to sign in with Google, we store the following in Google Firebase:

• Display name — shown on public leaderboards.
• Email address — used only to identify your account; never shown to other players.
• Account identifier (UID) — links your scores to your account.
• Profile picture URL — shown inside the app.
• Scores, times and levels — used for leaderboards and your personal record.
• Usage statistics: play time, last seen, number of app opens, number of ads watched, app version and language, approximate country — to improve the app, support players and prevent cheating. Never shown to other players.
• Notification token (if you allow notifications) — for friend invitations, challenge results and app news (Firebase Cloud Messaging).

Friends (optional)

If you use the friends feature, your account gets a short ID (e.g. K7M2QP) that only you share. We store your friends list (internal id and display name) and temporary game invitations, which expire automatically within one hour. By default nobody can search for you by name or email, and your email is never shown to other players.

Player directory (optional, off by default): if you turn on “Let other players find me”, signed-in players can see your in-game name, level, best streak, app language and friend ID so they can send you a friend request. Your photo and email are never shown. Turning it off removes you immediately. You can block or report any player; we store your block list and reports (reason and time) for review.

Sending coins to friends: we keep a record of each transfer (sender, receiver, amount, time) to prevent abuse. Coins are virtual in-game items with no monetary value and cannot be exchanged for money.

Advertising

The app shows ads through Google AdMob. Google — not us — collects device identifiers, the Advertising ID and technical device/network data to serve and measure ads and prevent fraud. See Google's Privacy Policy and How Google uses information from partner sites or apps. You can opt out of personalised ads in Android: Settings → Google → Ads.

Users in the EEA, the UK and Switzerland: the app shows a consent dialog on first launch, and no personalised ads are served before you consent. You can change your choice any time via the "Ads options" link at the bottom of the app's home screen.

Crash reports

When a technical error occurs, an automatic report is sent containing the error message, the screen it happened on, the app version, the device and OS type, and the time. It is used only to fix bugs and contains no name, email or scores.

Approximate country & ad statistics

We infer only your country, approximately, from the device language/region and time zone — no GPS and no location permission — and store it with a random device identifier and first/last use dates, to count players per country. We also keep aggregated daily counts of ad impressions to measure app performance. This data is never shown to other players.

What we never collect

• No precise location (no GPS or location permission), contacts, messages or call logs.
• No photos, files, microphone or camera access.
• No payment information — the app is free; optional in-app purchases (such as removing ads) are handled entirely by Google Play and we never see payment details.

3. Sharing

Data is processed by Google Firebase (database, sign-in, Analytics, Crashlytics, Cloud Messaging, App Check with Google Play Integrity), Google AdMob (ads) and Google Play (optional purchases). We do not sell your data or share it with anyone else for marketing.

4. Security & retention

All traffic is encrypted with HTTPS/TLS. Scores are kept while your account exists; on a deletion request all your data is removed within 30 days.

5. Deleting your data

See Data deletion request, or email AAA78JO@gmail.com from the address you signed up with.

6. Children

The app targets users aged 13 and above. We do not knowingly collect data from children under 13; if we learn we have, we delete it immediately.

7. Your rights

You may request a copy, correction or deletion of your data, or withdraw consent by signing out. Email AAA78JO@gmail.com; we reply within 30 days.

8. Changes

We may update this page. The date at the top shows the current version.
