Privacy Policy & Terms of Service · Last updated: 21 October 2026
This Privacy Policy explains how AJD Mobile ("we", "us") handles information when you use the mobile game Unscrew Master: Wood Puzzle (package com.devify.screwpuzzle, the "App"). By using the App you agree to this policy.
The App has no user accounts. We do not ask for your name, email address, phone number, contacts, photos, microphone, camera or precise location, and we do not run our own servers that store personal information about you.
Your game progress (level, coins, stars, boosters, purchases made with in-game coins, settings and streak data) is stored locally on your device. We do not receive it. Uninstalling the App deletes it.
The App is supported by advertising. We use Google AdMob (Google LLC / Google Ireland Limited), which may collect and process the following data directly from your device:
| Data | Purpose |
|---|---|
| Advertising ID (Android Advertising ID) and similar device identifiers | Serving and measuring ads, frequency capping, fraud prevention |
| IP address and approximate location derived from it | Serving ads, fraud prevention, regional legal compliance |
| Device and app information (model, OS version, language, app version) | Ad delivery, diagnostics |
| Ad interactions (impressions, clicks, ad events) | Ad measurement and reporting |
| Crash logs and diagnostics produced by the ad SDK | Stability and performance |
Google may use this data to show personalised or non-personalised ads, depending on your choices. Learn more in the Google Privacy Policy and How Google uses information from sites or apps that use its services. Ads are limited to content suitable for a general audience (maximum ad content rating "PG").
Other Google components used by the App: Google Play services and the Google Play In-App Review API (to ask you for a rating). These are governed by Google's policies. We use Android WorkManager to schedule an optional daily reminder notification, which is created locally on your device.
Processing for ad personalisation is based on your consent. Processing needed to deliver non-personalised ads, measure ads and prevent fraud is based on legitimate interests of us and our ad partners.
The App is not directed to children under 13 (or the minimum age in your country) and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the App, contact us and we will help remove it.
We do not store personal data on our own servers. Data processed by Google is handled under Google's retention policies. Depending on where you live, you may have the right to access, correct, delete, restrict or port your data, and to withdraw consent. Because we hold no personal data about you, requests relating to advertising data should be directed to Google (via your Google account's ad settings); you can also contact us at the address below and we will assist.
Google may process data in countries other than your own, using safeguards such as standard contractual clauses.
We may update this policy; the date above shows the latest version. Significant changes will be reflected in the App or on this page.
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on your devices for personal, non-commercial entertainment. You may not copy, modify, reverse engineer, decompile, or resell the App, nor use bots, cheats or exploits.
Coins, stars, boosters, themes and other in-game items have no cash value, cannot be exchanged for money, and are earned by playing or by optionally watching advertisements. We may adjust, reset or remove virtual items to maintain game balance or prevent abuse.
The App is supported by ads. Rewarded video ads are optional. Ads are provided by third parties; we are not responsible for third-party products, content or websites you reach through ads.
The App, its artwork, code, sounds and design are owned by AJD Mobile or its licensors and are protected by copyright and other laws.
You agree not to disrupt the App or misuse its features. We may suspend or end access if you breach these terms. You may stop using the App at any time by uninstalling it.
The App is provided "as is" without warranties of any kind. To the maximum extent permitted by law, we are not liable for indirect, incidental or consequential damages, or loss of progress or virtual items. Nothing in these terms limits rights you have under mandatory consumer law.
These terms are governed by the laws of your country/state, without regard to conflict-of-law rules, subject to mandatory consumer protections in your place of residence.
We may update these terms. Continued use after an update means you accept the new terms.
