Privacy Policy

Last updated: September 8, 2026

Waluku Studio ("we", "us", or "our") develops mobile applications for the Android and iOS platforms. This Privacy Policy describes how we collect, use, and disclose information when you use our applications and services.

By using our applications, you agree to the collection and use of information in accordance with this policy.

1. Overview

Waluku Studio develops and publishes various mobile applications. While many sections of this policy apply to all of our applications, the data each application collects may differ. When you use a specific application, the information that application collects is governed by this policy together with any application-specific section included below.

This policy applies to all mobile applications published by Waluku Studio unless a specific application provides its own separate privacy policy.

2. Information Collection and Use

For a better experience while using our applications, certain applications may require you to provide us with certain personally identifiable information. The specific information collected depends on the application you use and is described in the relevant application-specific section of this policy.

The information we request may be retained on your device or collected by us or our service providers, depending on the features you use.

Our applications may use third-party services that collect information used to identify you, such as statistics and advertising services. You should review the privacy policies of these third-party services for more information.

3. Log Data

Whenever you use our Service, in case of an error in the application, we may collect data and information (through third-party products) on your phone called Log Data. This Log Data may include information such as your device's Internet Protocol (IP) address, device name, operating system version, the configuration of the application when utilizing our Service, the time and date of your use of the Service, and other statistics.

4. Advertising and Tracking

Some of our applications display advertisements to support their services. These applications may use advertising services that collect advertising identifiers (such as the Advertising ID on Android or IDFA on iOS) to deliver and measure advertisements.

On iOS, we will ask for your permission through the App Tracking Transparency (ATT) prompt before using your advertising identifier for personalized or cross-app advertising. You can decline this request, and you may still use the application, though you may see fewer personalized ads.

For more details specific to applications that show ads, please refer to the relevant application-specific section below.

5. Service Providers

We may employ third-party companies and individuals due to the following reasons:

To facilitate our Service;
To provide the Service on our behalf;

To assist us in analyzing how our Service is used.

We want to inform users of this Service that these third parties may have access to your Personal Information. The reason is to perform the tasks assigned to them on our behalf. However, they are obligated not to disclose or use the information for any other purpose.

6. Security

We value your trust in providing us your Personal Information, and we strive to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage, is 100% secure and reliable, and we cannot guarantee its absolute security.

Our applications or website may contain links to other sites. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by us. Therefore, we strongly advise you to review the Privacy Policy of these websites. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites or services.

8. Children's Privacy

Our applications are intended for general audiences. We do not knowingly collect personally identifiable information from children under the age of 13. In the case we discover that a child under 13 has provided us with personal information, we will immediately delete this from our servers. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we will be able to take the necessary actions.
