Privacy Policy

Effective 22 August 2026 · Last updated 3 November 2026

This policy applies to all mobile applications published by zTommyzGaming ("we", "us") on Google Play, and to the browser version of Dig A Museum on CrazyGames. It explains what happens to information when you use our games. Sections 1 to 5 describe our Android apps. The browser version works differently, and section 6 describes it.

1. Information we collect

We collect a small amount of anonymous usage data through two Google services: Google Analytics for Firebase and Google AdMob. Specifically:

• Gameplay events — which level you started, whether you completed it, how many hints you used, and whether you opened the shop. These tell us where a game is too hard or too confusing.
• Device identifiers — a Firebase installation ID and, on Android, the Advertising ID. These let us count returning players without knowing who they are, let us tell whether someone found the game through an ad we paid for, and let AdMob avoid showing you the same ad over and over.
• Device and app information — device model, operating system version, app version, language, and approximate country. Country is derived from your IP address; we never see or store the IP address itself.
• Ad interactions — whether a rewarded ad was requested, shown, watched to the end, or closed early. Google uses this to decide which ads to send and to detect fraudulent traffic.
• Diagnostic information — crash reports and performance measurements from the ad component, collected by Google so the ad system keeps working.

Information you choose to send us

Some games have a Send feedback screen and a Redeem code screen. Nothing is sent from them unless you tap Send or Redeem. When you do, the app sends our own server, over an encrypted connection:

• Feedback — the message you wrote, the category you picked, and an email address only if you chose to type one so we can reply. It comes with the in-game player ID shown at the bottom of Settings (a random code created on your device, not linked to your name or Google account), the app version, device model, game language, and your highest level, so we can reproduce the problem. Our server records your approximate country but never stores your IP address.
• Gift codes — the code you typed and your in-game player ID, so a single-use code cannot be claimed twice.

Apart from what you type into those screens, we do not collect your name, email address, phone number, contacts, photos, precise location, or the contents of any file on your device.

2. Advertising in our games

Our games contain no forced advertising. There are no banners, no ads between levels, no ads when you open the app, and nothing that interrupts a game in progress.

The only ads we show are rewarded ads: a video you can choose to watch in exchange for something in the game, such as extra coins or a hint. Nothing happens unless you tap the button. If you never tap it, you will never see an ad. Everything a rewarded ad gives you can also be earned by playing, or bought outright without ads.

These ads are served by Google AdMob. Google selects which ad to show, and may use the device identifier described in section 1 to do so. We do not see who watched what.

3. Data stored on your device

Your game progress, settings, and purchase records are saved locally on your device so you can continue where you left off. Uninstalling the app deletes it.

If you are signed in to Google Play Games, some games also keep a copy of your progress in your own Google account (Saved Games), so you can continue on a new phone. That copy is stored by Google in a private app folder of your Google Drive; we have no way to read it. You can delete it from your Google account settings at any time.

4. Purchases

If you buy something in one of our apps, the purchase is processed entirely by Google Play Billing. Payment details are handled by Google and are never sent to us or seen by us. Google's handling of that transaction is governed by the Google Privacy Policy.

We receive only aggregated, anonymous sales statistics through the Google Play Console — for example, how many copies were sold in a country. These figures cannot identify an individual.

Our analytics also records that a purchase happened, which item it was, and which level you were on at the time. This tells us which moments in a game people find worth paying for. It contains no payment details and no name.

5. Third-party services

Our apps embed Google Analytics for Firebase. Google processes the usage data described in section 1 on our behalf, on servers that may be located outside your country, under the Firebase Privacy and Security terms and the Google Privacy Policy.

Our apps also embed the Google Mobile Ads SDK (AdMob) to serve the rewarded ads described in section 2. Google collects and processes IP address, ad interactions, diagnostic information, and device identifiers for advertising, analytics, and fraud prevention, encrypted in transit. Google's use of that data is governed by the How Google uses information from sites or apps that use our services and the Google Privacy Policy.

We also run advertising campaigns on Google Ads to let people know our games exist. When you install a game after seeing one of those ads, Google tells us that an install came from that campaign. It does not tell us who you are.

Some games use Google Play Games Services for achievements and Saved Games. If you sign in, Google handles that under the Google Privacy Policy; we only learn that an achievement was unlocked.

Feedback and gift-code requests (section 1) are received by our own small server, hosted by Vercel on our behalf. Vercel stores the messages for us and does not use them for anything else.

Our apps contain no social media SDKs and no third-party crash-reporting service. Everything else goes through Google Play itself, for app distribution and billing.

6. Dig A Museum in your web browser

Dig A Museum can also be played in a web browser on CrazyGames (crazygames.com). It is the same game as the Android app, built with Unity and shown inside a CrazyGames page. Because it runs in a browser, it handles data differently. This section describes everything it does.

What the browser version does not use

The browser version contains no Google Analytics for Firebase, no Google AdMob, no Google Play Billing, and no Google Play Games cloud save. It does not use the Android Advertising ID. It has no purchases of any kind, so no payment is ever processed.

Analytics without cookies

We use Google Analytics through the Google tag (gtag.js) to see which levels people find too hard. It runs with Google's consent mode set to "denied" for analytics storage, ad storage, ad user data, and ad personalisation. As a result, the game itself sets no analytics cookies, and Google receives only cookieless measurement pings. Google signals and ad personalisation are turned off. Google receives:

• Gameplay events — the same kinds as in the Android app: which level you started or completed, which items you used, whether you opened the shop, and similar.
• Your in-game player ID — a random code of 8 characters, created by your browser and saved in its storage. It is not linked to your name, email address, or CrazyGames account. We send it as the Google Analytics user ID so we can count returning players without knowing who they are.
• Browser and device information — browser and device type, and language.
• Approximate country — Google derives it from your IP address; we never see or store the IP address itself.

Ads served by CrazyGames

The only ads are rewarded ads you choose to watch, as described in section 2. There is nothing to buy, so anything a rewarded ad gives you can also be earned by playing. In the browser version these ads are served by CrazyGames through the CrazyGames SDK. We do not run any ad network of our own on the web. CrazyGames runs the website the game is shown on, and it is responsible for its own cookies and the data its ads use, under the CrazyGames Privacy Policy.

Where your progress is saved

Your progress and settings are saved in your browser's storage on your device. Clearing your browser data removes them. If you are signed in to a CrazyGames account, a copy of your progress is also saved to that account through the CrazyGames SDK, so you can continue on another device. CrazyGames stores that copy under its own privacy policy.

Our own server and game files

The Send feedback, Redeem code, and Inbox screens work the same way as in the Android app. Nothing is sent unless you use them. When you do, the game sends our server, over an encrypted connection, your in-game player ID, the game's package name, and the code you typed or the feedback you wrote. An email address is included only if you chose to type one. We handle it as described in sections 1, 5, and 8. In the browser version, feedback can only be sent from inside the game; there is no option to send it through your email app.

The game also downloads its settings and level updates as plain files from Firebase Hosting, a Google service. Those requests carry no player data beyond what any web request carries, such as the IP address needed to deliver the file.

7. Your choices about ads

You can stop watching them at any time. Rewarded ads are optional by design; declining one costs you nothing except the reward it offered.

You can reset or delete your Advertising ID in Android settings: Settings → Privacy → Ads. Deleting it stops advertisers from linking your activity across apps. Ads may still appear, chosen without any history.

If you are in the European Economic Area, the United Kingdom, or Switzerland, our apps ask for your consent before any personalised advertising, using Google's User Messaging Platform. You can change that answer at any time from Settings → Privacy settings inside the app. Declining is a valid choice and the game remains fully playable.

If you are in a United States state with an applicable privacy law, the same in-app privacy screen lets you opt out of the sale or sharing of your information for targeted advertising.

In the browser version, there is no Advertising ID to reset. Rewarded ads are still optional, and choices about the ads CrazyGames serves are described in the CrazyGames Privacy Policy.

8. How long we keep it

Usage data in Google Analytics for Firebase is retained for 14 months and then deleted automatically. Usage data from the browser version is kept in Google Analytics for no longer than 14 months. Data held by Google AdMob is retained according to Google's own retention schedule. Aggregate reports, which contain no identifiers at all, may be kept longer.

Feedback messages are kept only as long as we need them to answer you and fix the problem. Records of used gift codes are kept so a code cannot be claimed twice. You can ask us to delete either at any time (section 10).

9. Children

Our apps are directed at people aged 13 and over. They are not designed for, marketed to, or intended for children under 13, and we do not knowingly collect information from children. We do not serve personalised advertising to anyone we have reason to believe is under the age of consent in their country. If you believe a child has used one of our apps and you would like their data removed, email us and we will delete it.

The same applies to the browser version of Dig A Museum on CrazyGames: it is intended for players aged 13 and over. We do not run any advertising of our own there, and the analytics we use in the browser set no cookies and are not used for advertising. If a child under 13 has played it and you would like the data linked to their in-game player ID removed, email us with that ID and we will delete it.

10. Your rights

You can ask us what data is associated with your device, ask us to delete it, or ask us to stop collecting it. Because we identify devices only by an anonymous ID, we will ask you to send us that ID from inside the app so we can find the right records. For feedback and gift codes, that is the player ID shown at the bottom of the Settings screen. Email us and we will explain how.

The quickest route to stopping collection entirely is to reset or delete your Advertising ID in Android settings, or to uninstall the app.

In the browser version, clearing your browser data deletes the progress and player ID stored in that browser. To have records tied to your player ID deleted, email us that ID as described above. A copy of your progress saved to a CrazyGames account can be removed through CrazyGames.

11. Changes to this policy

If a future version of an app collects anything beyond what section 1 describes, we will update this page and change the "last updated" date above before that version is released, never afterwards. Material changes will also be noted in the app's release notes on Google Play.
