This Privacy Policy explains how the mobile game Bres Tis Lexis ("the App", "we", "us") handles information when you use it on Android and iOS. The App is provided by Nikolaos Kalaitzidis ("the Developer"), who is the data controller for the purposes of the EU/UK General Data Protection Regulation (GDPR).
Bres Tis Lexis is a Greek vocabulary word game. We do not require an account and we do not ask you for your name, email address, or phone number. The App is supported by advertising and an optional one-time "Remove Ads" purchase.
We do not ourselves collect personally identifying information. The third-party SDKs the App uses collect and process the following categories of data:
| Data | Collected by | Purpose | Shared |
|---|---|---|---|
| Advertising identifier (Android Advertising ID / Apple IDFA) | Google AdMob; Google Analytics for Firebase (when analytics collection is on) | Serving ads, frequency capping, and personalisation (only with ad consent). Analytics may also read the advertising ID when collection is on. | Shared with Google and advertising partners |
| Device & other identifiers and device information (model, OS version, language, network info) | Google AdMob; Firebase Crashlytics; Google Analytics for Firebase | Ad delivery, fraud prevention, crash diagnostics, and usage measurement | Shared with Google |
| Approximate (coarse) location, derived from IP address | Google AdMob / Google User Messaging Platform; Google Analytics for Firebase (masked IP) | Geo-appropriate ads, detecting whether consent is legally required, and coarse Analytics location | Shared with Google |
| App activity (ad impressions, clicks) | Google AdMob | Ad measurement and performance | Shared with Google |
| Diagnostics (ad SDK performance / crash data from ads) | Google AdMob | SDK functionality and reliability | Shared with Google |
| Crash logs, app state at crash time, Crashlytics installation UUID, and Firebase installation ID | Firebase Crashlytics (and its Firebase Installations / Sessions components) | Diagnosing crashes. Collected only after the consent flow finishes and you allow personalised ads (plus App Tracking Transparency on iOS). Off before that, and off if you decline. Google retains crash reports for 90 days. | Processed by Google; visible to the Developer in Firebase as crash reports, not as a name or email |
| Anonymous play analytics (app-instance ID; session / app-open events; stage start and finish; which clue was found and whether Help was used — never the clue or answer text) | Google Analytics for Firebase | Understanding how the game is played. Collection stays off until the consent flow finishes and analytics storage is allowed (or Google’s form is not required in your region). The SDK may also record in-app purchase events (product id, name, and price) when collection is on. We do not set a user ID. | Processed by Google; visible to the Developer in Firebase Analytics |
| Purchase status of the "Remove Ads" product | Google Play / Apple App Store | Unlocking the ad-free experience and restoring purchases | Processed by the app store; not received by the Developer in identifiable form |
We do not collect your precise GPS location, contacts, photos, files, or messages. We do not use Facebook, or any other analytics or crash SDK besides Google AdMob, Google User Messaging Platform, Firebase Crashlytics, and Google Analytics for Firebase. We do not attach your name or email to crash reports or analytics events.
Ads are provided by Google AdMob
(Android: play-services-ads; iOS: Google Mobile Ads). How Google uses information from
apps that use its services is described in
Google's
partner policy and the
Google Privacy Policy.
If you are in the European Economic Area, the United Kingdom, or Switzerland, the App uses Google's User Messaging Platform (UMP) to ask for your consent before any personalised ads are shown. If you do not consent, you will still see ads, but they will be non-personalised.
On iOS, the App also presents Apple's App Tracking Transparency prompt. The advertising identifier (IDFA) is only used for tracking if you allow it; if you decline, ads are non-personalised. iOS also registers Apple SKAdNetwork identifiers so AdMob and its partners can measure installs without the IDFA.
Where Google does not require a consent form (typically outside the EEA/UK/Switzerland), UMP reports that consent is not required. Personalised ads may then run without that form; on iOS, App Tracking Transparency still applies.
The App includes Firebase Crashlytics so we can see why the game crashed (stack traces, app and device state, and installation identifiers). Collection is off by default on both Android and iOS and stays off until the consent flow has finished.
After that, Crashlytics turns on only if personalised ads are allowed (the same choice as IAB advertising purpose 4). On iOS you must also allow tracking in App Tracking Transparency. If you decline, collection stays off and any crash reports waiting to send are deleted. Changing ad preferences later turns collection on or off the same way. If Google does not require a consent form in your region, Crashlytics may turn on together with personalised ads (still subject to App Tracking Transparency on iOS).
We do not send custom user IDs or extra developer keys with crash reports. If both Crashlytics and Analytics are on, Crashlytics may include recent Analytics events as “breadcrumbs” immediately before a crash. We do not ship native (NDK) crash collection. Google retains Crashlytics crash data for 90 days (see Firebase Privacy and Security).
The App includes Google Analytics for Firebase so we can see anonymous play (sessions, when a stage starts or finishes, and when a clue is found — including whether Help was used). Clue text and answers are never sent. We do not log Word Book use, Game Reset, or a custom app-open event (the SDK records its own session events).
Analytics collection is off by default. It turns on only after the consent flow finishes and analytics storage is allowed — or Google’s form is not required in your region. This is a different choice from personalised ads. Declining App Tracking Transparency on iOS does not turn analytics off by itself. Declining analytics, or later withdrawing it in privacy options, turns collection off again.
When collection is on, Google’s SDK may also record automatic events such as first open, session start, and in-app purchases. We do not set a Firebase user ID. Google processes this data under the Firebase and Google privacy policies.
The App offers a one-time, non-consumable Remove Ads purchase. Payments and purchase verification are handled entirely by Google Play Billing (Android) or StoreKit (iOS). We do not collect or store your payment details. The App only stores a local flag on your device indicating whether ads have been removed; this is re-verified with the store and can be restored via "Restore purchases".
After you finish a stage, the App may invite you to rate it using Google Play In-App Review (Android) or Apple's SKStoreReviewController (iOS). That interaction is handled by the store. We do not receive the text of your review through the App.
The following stay on your device and are not sent to the Developer:
On Android, the App does not participate in automatic backup (allowBackup is off).
Uninstalling the App removes this local data. Game Reset in Settings clears stage progress and
starts again from stage 1; it does not cancel a Remove Ads purchase. (If you have device backup
enabled on iOS, your operating system may include this data in your own cloud backup, which is
governed by your device provider.)
If you are in the EEA or UK, you have the right to access, rectify, erase, restrict, or object to the processing of your personal data, and to withdraw consent at any time. Where we rely on a legal basis, that basis is your consent for personalised advertising, for Crashlytics (the same personalised-ads choice), and for analytics storage. Google may process this data in the United States or other countries where Google or its agents operate. To exercise these rights, contact us at the address below. You also have the right to lodge a complaint with your local data protection authority.
The App is not directed to children under 13 (or the equivalent minimum age in your country), and we do not knowingly collect personal data from children. If you believe a child has provided personal data, please contact us and we will take appropriate steps.
We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the latest version. Material changes will be communicated through the App or its store listing.
