Last updated: 9 November 2026
This Privacy Policy explains how Gizmo Studio (“we”, “us”) handles information in the mobile apps we publish on Google Play (each an “App”) and on this website, gizmostudio.xyz. Gizmo Studio is a small independent app studio based in Singapore. Our Google Play developer page is Gizmo Studio.
1. The short version
- Our Apps have no accounts and no sign-in. We do not ask for your name, email or phone number.
- Your settings, progress, favourites and creations are stored on your device only.
- Free Apps show ads from Google AdMob. Google collects some device data to show and measure those ads.
- Purchases are handled by Google Play. We never see your payment details.
- We do not sell your personal information.
2. Information stored on your device
Apps save your preferences (such as theme, font size or sound settings), your progress (such as reading position, scores or completed puzzles), favourites and anything you create in the App. This information stays on your device. We do not receive it. It is removed when you uninstall the App or clear its data in Android settings.
Some drawing, colouring and puzzle Apps let you choose a picture from your device. The picture is opened and processed on your device only and is never uploaded to us.
3. Advertising (Google AdMob)
Free Apps display ads served by Google AdMob, and some Apps offer an optional rewarded ad that you can choose to watch. To serve, personalise, measure and limit fraud on ads, Google may collect:
- your device’s advertising ID,
- IP address, and approximate location derived from it,
- device and app information (such as model, operating system and language),
- ad interactions (such as ads viewed or tapped).
Google acts as an independent controller of this data. See How Google uses information from sites or apps that use its services and the Google Privacy Policy.
You can reset or delete your advertising ID, or opt out of personalised ads, in your device’s settings (Settings > Google > Ads, or Settings > Privacy > Ads, depending on your device). You can also manage ad preferences at adssettings.google.com.
Ads in our Apps are restricted to family-appropriate content ratings.
4. In-app purchases
Purchases (such as removing ads or unlocking features) are processed by Google Play under the Google Payments Privacy Notice. Google Play tells the App whether a purchase was made so it can unlock what you bought. We do not receive your name, email address or payment details.
5. Content our Apps download
Apps may download a list of our other apps from gizmostudio.xyz to show in a “More apps” section. Like any web request, this reveals your IP address and basic device information to our web host, which may keep it in standard server logs for security and troubleshooting. No other information is sent.
6. When you email us
If you contact us by email, for example through an App’s feedback option, we receive your email address and whatever you write. We use it only to reply and to improve our Apps. We never use it for marketing, and we will delete it on request.
7. This website
This website runs on WordPress and uses web analytics (Google Analytics) and cookies to understand how it is used. If you leave a comment, we keep the details you enter, plus your IP address and browser user agent, to help detect spam. An anonymised hash of your email may be sent to the Gravatar service to show your profile picture (Automattic Privacy Policy). Comments and their metadata are kept until you ask us to delete them. Embedded content (such as videos) from other websites behaves as if you had visited that website.
8. Children
Our Apps are designed for a general audience and are not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has sent us personal information, please contact us and we will delete it.
9. Legal bases (EEA and UK)
Where the GDPR or UK GDPR applies, we rely on: your consent (for personalised advertising where required, and for website cookies); our legitimate interests (operating, securing and improving our Apps and website, showing non-personalised ads, and answering your messages); and performance of a contract (delivering what you buy).
10. Your rights
Depending on where you live (including under the GDPR, UK GDPR, Singapore’s Personal Data Protection Act and California law), you may have the right to access, correct, delete, restrict or object to the use of your personal information, to data portability, and to withdraw consent at any time. Because our Apps keep your data on your device, you can delete most of it yourself by clearing the App’s data or uninstalling it. For anything we hold, such as emails, contact us at the address below and we will respond as soon as we reasonably can. You also have the right to complain to your local data protection authority.
11. Sharing and transfers
We share information only with the service providers described above (Google and our web host), or where required by law. These providers may process information in countries other than your own, including the United States, under their own safeguards.
12. Security
This website uses HTTPS encryption. Anyone at Gizmo Studio who handles your messages or requests treats them as confidential and uses them only for the purposes in this policy. Because our Apps store your data on your device, its security also depends on your device’s protections, such as a screen lock.
13. Changes to this policy
We may update this policy from time to time. The “Last updated” date at the top shows the latest version.
