Privacy Policy
Worm Puzzle
Last updated: 10 September 2026
The short version. Worm Puzzle has no accounts and no sign-in. We do not ask you for your name, email address, or any other personal detail, and we do not collect or store any personal information on our own servers. Your game progress stays on your device. The app shows ads supplied by Google AdMob, and Google receives limited device information in order to serve them. When you first open the app it asks your age; players under 13 only ever receive non-personalised, child-directed ads. Players 13 and over may be asked for permission to use their device advertising identifier for personalised ads — that request is always optional, and declining it simply means you see non-personalised ads instead. That is the entire extent of data handling in this app.
1. Who we are
Worm Puzzle (“the app”, “we”, “us”) is published by AppUnik. If you have any question about this policy or about privacy in the app, contact us at info@appunik.com.
2. Information we do not collect
We want to be explicit about this, because it covers most of what people worry about. The app does not:
- require an account, login, or registration of any kind;
- ask for your name, email address, phone number, or postal address;
- access your contacts, photos, camera, microphone, calendar, or files;
- collect or record your precise location;
- transmit your game progress, scores, or settings off your device;
- send any information to servers operated by us — we run none;
- sell any information about you to anyone.
The one exception to “nothing leaves the device” is advertising. Google AdMob is built into the app and does receive device information when an ad is requested. Section 4 sets out exactly what, and how you control it.
3. Information stored on your device
To make the game work, the app saves the following locally, in your device's own app storage:
- your level progress, star ratings, and which levels are unlocked;
- your remaining lives and in-game timer state;
- your preferences, such as whether music and sound effects are switched on;
- whether you answered the age question as under 13 or 13 and over — see section 4.
This information never leaves your device. We cannot read it, and it is not backed up to any server we control. Deleting the app removes all of it permanently.
4. The age question
Worm Puzzle is played by families, so the first time you open the app it asks a single neutral question: how old you are. This is asked once, before any ad is requested.
Your answer is not stored as a number and never leaves your device. The app keeps only which of two brackets you fall into — under 13, or 13 and over — and uses it to decide how ads are requested for you, as described in section 5. We do not transmit the bracket, your age, or your birth date to us or to Google; it only changes the settings the app applies locally to its own ad requests.
Until the question is answered, the app treats the player as a child, which is the more protective of the two settings.
5. Advertising
Worm Puzzle shows two kinds of ad, both provided by Google AdMob: optional rewarded video ads — for example, to earn an extra life or extra time, which you choose to watch — and a full-screen ad shown periodically after completing a level. The game is fully playable without ever watching a rewarded ad.
When an ad is requested, Google may receive and process:
| Data | Purpose |
|---|---|
| Device advertising identifier | Frequency capping, ad measurement, fraud prevention, and — where permitted, see below — ad personalisation |
| Device and app information (model, operating system version, app version, language) | Delivering an ad that renders correctly on your device |
| IP address, and coarse country/region derived from it | Serving region-appropriate ads and meeting legal requirements |
| Ad interaction events (an ad was shown, watched, or closed) | Measuring ad delivery and paying the developer |
Personalised and non-personalised ads
Which of the two you receive depends on your answer to the age question and, on iOS, on a permission prompt.
| If you are… | What the app requests |
|---|---|
| Under 13, or you have not yet answered the age question | Non-personalised, child-directed ads only. The app tags every request for child-directed treatment under COPPA and limits ad content to a general audience rating. No tracking permission is requested, and the advertising identifier is not used to build a profile. |
| 13 or over, and you granted the tracking permission | Personalised ads. Google may use your advertising identifier to select ads based on a profile of your interests, including activity in other apps and websites. |
| 13 or over, and you declined the tracking permission | Non-personalised ads. Ads are selected from general context rather than from a profile of your interests. |
Tracking, and the iOS permission prompt
On iOS, players aged 13 and over are shown Apple's App Tracking Transparency prompt asking for permission to track. “Tracking” here has Apple's specific meaning: linking your device advertising identifier with data from other companies' apps and websites for advertising purposes. Granting it is entirely your choice, the game is identical either way, and you can change your mind at any time in Settings → Privacy & Security → Tracking. Under-13 players are never shown this prompt.
On Android there is no equivalent system prompt; personalisation follows your device's own advertising ID settings together with your age answer.
Consent in the EEA, the UK, and Switzerland
If you are in a region where consent is legally required, the app additionally shows Google's consent form before ads are personalised, and your choices there are respected by Google's advertising partners. You can reopen and change those choices from the privacy options in the app where they are offered.
Google's handling of this data is governed by its own policies, not ours:
Controlling ad personalisation
- iOS: Settings → Privacy & Security → Tracking, and Settings → Privacy & Security → Apple Advertising.
- Android: Settings → Google → Ads, where you can delete or opt out of your advertising ID.
6. Children's privacy
Worm Puzzle is a general-audience puzzle game suitable for families. It is not directed specifically at children under 13, but we know children play it, which is why the app asks the age question described in section 4 rather than assuming.
Players who answer under 13 — and any player who has not answered yet — receive child-directed treatment: ad requests are tagged under the Children's Online Privacy Protection Act (COPPA), ad content is restricted to a general-audience rating, ads are never personalised, and no tracking permission is requested. We do not knowingly collect personal information from children. Because the app has no accounts, no messaging, no user-generated content, and no social features, there is no mechanism by which a child could submit personal information to us.
If you are a parent or guardian and believe a child has provided personal information through this app, or answered the age question incorrectly, please contact us at info@appunik.com and we will act on it promptly. Reinstalling the app clears the stored answer and asks the question again.
7. Permissions the app uses
| Permission | Why |
|---|---|
| Internet access | Required solely to load advertisements. All gameplay works offline. |
| Vibration / haptics | Tactile feedback when a move is blocked or a level is completed. |
| Tracking (iOS only, optional) | Apple's App Tracking Transparency prompt, shown only to players aged 13 and over. Granting it allows personalised ads; declining changes nothing about the game. See section 5. |
8. Your rights
Depending on where you live, you may have rights under the GDPR, the UK GDPR, the CCPA/CPRA, or similar laws — including rights to access, correct, delete, or port your personal data, and to object to its processing.
We operate no servers and hold no personal data about you ourselves, so there is nothing on our side for us to retrieve, amend, or erase. All data the app stores is on your own device and is deleted when you uninstall the app. For data held by Google in connection with advertising, please exercise your rights directly with Google using the links in section 5, or use the device-level advertising controls described there.
“Sale” and “sharing” under the CCPA/CPRA. We do not sell personal information for money. However, when a player aged 13 or over has permitted personalised ads, the resulting use of the advertising identifier for cross-context behavioural advertising may be treated as “sharing” under the CPRA. You can opt out at any time, and doing so is built into the app rather than requiring a request to us: decline or revoke the tracking permission on iOS, or opt out of ad personalisation in your Android advertising ID settings. Either one moves you to non-personalised ads immediately. Players under 13 are never included in this, and we do not knowingly sell or share the personal information of anyone under 16.
9. Data retention and security
We operate no servers and no databases for this app, so we retain nothing. Data stored on your device is protected by your device's own operating system security and is removed when you delete the app.
10. Changes to this policy
If we change how the app handles data — for example, by adding a new feature — we will update this page and revise the “Last updated” date above. Material changes will also be noted in the app's store listing release notes. Please review this page from time to time.
