AlibiDoku Privacy Policy

Last updated: August 31, 2026
Effective: August 31, 2026

Welcome to AlibiDoku (the “App”). We respect your privacy. This Policy explains how information relating to you is handled when you use the App. If you do not agree with it, please do not use the App.

1. Who We Are

We operate the App and are responsible for the related processing of personal information.

Contact: wangziwei9401@gmail.com

2. Information We Handle

The App currently requires no account or sign-in. It does not request your name, phone number, email address, government identifier, contacts, precise location, camera, microphone, photos, or advertising identifier.

To provide its basic features, the App stores the following on your device:

• started and completed cases;
• challenge results, including best stars and time, clear count, hints used, and wrong-submission totals;
• board placements, notes, and puzzle state;
• first-tutorial completion; and
• your selected language.

We use this data only to restore gameplay, show progress, and remember settings. We do not use it for profiling, personalized advertising, or automated decision-making.

To understand App usage and fix stability issues, the App uses Firebase Analytics and Firebase Crashlytics to process:

• an app-instance or installation identifier and basic device, operating-system, and App-version information;
• gameplay interaction events, such as difficulty, case number, scene, grid size, level start, hint use, submission result, completion time and stars, restart, and exit; and
• crash stacks, App state, and limited current-case context when a crash or non-fatal error occurs.

These events do not contain suspect names, clue text, free-form input, or advertising identifiers. We use them only for analytics, gameplay improvement, and fault diagnosis—not for advertising, cross-app tracking, profiling, or automated decisions.

3. Local Storage and iCloud Sync

The App keeps gameplay progress on your device. When you are signed in to iCloud and allow the App to use iCloud, completed cases, challenge results, board placements and notes, saved attempts, and case-edition information automatically sync through Apple’s iCloud key-value storage to devices using the same Apple Account. Language, sound, haptics, and first-tutorial status stay on this device. We do not receive your Apple Account password or share synced data with other users or use it for advertising.

iCloud sync requires available Apple services and a network connection and may be delayed. Offline play remains available. Completed cases and best achievements are merged; the most recently saved unfinished version is used for each case. A board currently in use is not immediately replaced; synced saves are read when reopening a case. You can manage the App’s iCloud permission in system settings. Resetting all progress in the App also resets synced gameplay progress in iCloud. Deleting the App alone does not delete cloud copies. Apple handles synced data under its applicable terms and privacy policy.

4. System Permissions and Third-Party Services

The App currently requests no camera, microphone, photo, contact, location, Bluetooth, tracking, or notification permission.

The App uses SnapKit, an on-device user-interface layout library. It provides no account, advertising, analytics, or network service and does not transmit your personal information to its developer through the App.

The App uses Firebase Analytics and Firebase Crashlytics provided by Google LLC. Google processes the analytics and diagnostic information described above to provide usage measurement and stability monitoring. Retention and deletion follow the Firebase project settings and applicable Google policies. The App does not display ads, does not access IDFA, and does not use these services for cross-app tracking.

Apple may independently process account, device, download, or diagnostic information when you download or update the App through the App Store. When iCloud sync is enabled, Apple also handles the data necessary to provide iCloud key-value storage.

5. Sharing, Transfer, and Public Disclosure

We do not sell or publicly disclose your information, or provide it to third parties for their advertising purposes. To provide analytics and fault diagnosis, the App sends the limited analytics and diagnostic information described above to Google LLC through Firebase. Full board progress and language preferences remain stored locally. Future iCloud sync will provide sync data only to Apple’s iCloud/CloudKit infrastructure; it will not use a public database or expose data to other users.

If a future feature requires processing or sharing information with another recipient, we will update this Policy and provide notice, obtain consent, or establish another lawful basis before enabling it, except where law provides otherwise.

6. Information Security

We take measures appropriate to the App’s functions to protect local data and follow data-minimization principles. Please protect your device and system account. No security measure can guarantee absolute security; if a security incident may affect your rights, we will take remedial and notification measures as required by applicable law.

7. Your Rights

You can view gameplay progress, challenge statistics, and language settings in the App. You can reset local gameplay progress and challenge results in Settings, or clear App data by deleting the App. Use Apple’s backup controls for copies in a device backup. If future iCloud sync is launched, you will also be able to manage sync and cloud copies through the available controls and Apple’s iCloud storage settings.

To ask about this Policy, make a complaint, or exercise applicable access, copy, correction, deletion, or consent rights, contact us at the address above. Because the App has no account system and analytics or diagnostics are ordinarily associated only with an app-instance identifier, we may be unable to locate a particular record from your contact details alone. We will respond after reasonable verification within the period required by law.

8. Children

The App does not request age or identity information and does not knowingly collect children’s personal information. Minors should read this Policy and use the App with a parent or guardian’s guidance. If we later process personal information of children under 14, we will obtain guardian consent and take the measures required by law.

9. Updates to This Policy

We may update this Policy when features, processing practices, or legal requirements change. For material changes, we will provide appropriate notice, such as an in-App notice, and seek renewed consent where required by law. The updated Policy applies from its stated effective date.

10. Contact Us

Email: wangziwei9401@gmail.com

We generally aim to respond within 15 working days after receiving and reasonably verifying a request. You may also complain to a competent privacy or consumer authority.
