This Privacy Policy explains how EXO ("we", "us", or "our") handles information in connection with the mobile application Paper Fold: Learn & Craft (the "App").
Paper Fold: Learn & Craft is an educational and creative application that provides step-by-step instructions for paper folding, origami, and paper crafts.
The App does not require users to create an account or provide personal information to use its core features.
The App is free to use and is supported by advertisements provided through Google AdMob.
The App does not require registration, login, or a user profile.
We do not directly ask you to provide:
Name
Email address
Phone number
Password
Home address
Payment information
If you contact us by email for support, we may receive your email address and the contents of your message so that we can respond to your request.
The App uses Google AdMob to display advertisements.
Google AdMob may collect or process certain information automatically, which may include:
Device information
IP address
Advertising identifiers, where permitted
App interaction information
Advertising and diagnostic information
Approximate location derived from IP address
This information may be used to provide, personalize, measure, and improve advertisements, subject to applicable laws and your device or privacy settings.
Where applicable, the App may request your permission through Apple's App Tracking Transparency (ATT) framework before allowing advertising or measurement technologies to track you across apps and websites owned by other companies.
If you do not grant tracking permission, advertisements may still be displayed, but certain personalized advertising or measurement features may not be available.
For more information, please review Google's Privacy Policy:
Information may be used for the following purposes:
Provide origami and paper-folding instructions.
Display advertisements.
Measure advertising performance.
Maintain and improve the App.
Respond to support requests.
Detect and prevent fraud or abuse related to advertising.
We do not require users to create accounts and do not use information directly provided to us to create user profiles for unrelated purposes.
The App uses Google AdMob as its advertising provider.
AdMob may use device information, advertising identifiers, IP addresses, and other information to provide and measure advertisements.
Depending on the user's location, applicable laws, Apple's privacy requirements, and the user's privacy choices, advertisements may be personalized or non-personalized.
On iOS, certain forms of tracking across apps and websites require user permission under Apple's App Tracking Transparency framework.
Users can manage applicable tracking permissions through:
Settings → Privacy & Security → Tracking
Users may also have access to additional advertising and privacy controls provided by Apple, Google, or applicable third-party services.

Google Advertising Technologies
The App uses Google AdMob to display advertisements.
AdMob is operated by Google LLC. Google may process information collected through its advertising SDK according to Google's Privacy Policy and applicable laws.
The App is distributed through Apple's App Store.
Apple may independently collect and process information related to app downloads, installations, updates, ratings, reviews, purchases, and use of App Store services according to Apple's applicable policies.
The App does not offer in-app purchases or subscriptions.
For more information about Apple's privacy practices:
We do not sell, rent, or trade personal information directly collected by us.
Information may be processed by third-party service providers when necessary to operate the App, including:
Google AdMob for advertising and advertising measurement;
Apple for App Store distribution and platform services;
Other service providers where necessary to provide technical or support services;
Government authorities when required by applicable law or valid legal process.
Third-party providers process information according to their own privacy policies.
We do not intentionally sell personal information collected directly by EXO.
The App does not require user accounts and does not maintain a centralized database of user profiles.
Information processed by Google AdMob is retained according to Google's policies and practices.
If you contact us by email, we retain your correspondence only for as long as reasonably necessary to respond to your request, provide support, maintain records, or comply with legal obligations.
We take reasonable measures to protect information handled by us.
Network communications use appropriate security measures, such as HTTPS/TLS where supported.
However, no method of electronic transmission or storage is completely secure.
Because the App does not require accounts or store user profiles on our servers, we do not maintain a centralized database of personal user information.
EXO operates from the Socialist Republic of Vietnam.
Third-party service providers, including Google and Apple, may process information on servers located in countries outside Vietnam or your country of residence.
Where applicable, these providers use appropriate safeguards for international data transfers in accordance with applicable laws and their privacy policies.
Depending on your location and applicable law, you may have rights regarding your personal information, including the right to:
Access your personal information;
Request correction or deletion;
Object to or restrict certain processing;
Withdraw consent where applicable;
Opt out of certain personalized advertising;
Manage tracking permissions where applicable under Apple's App Tracking Transparency framework.
Information processed by Google is subject to Google's privacy controls and policies.
Information processed by Apple is subject to Apple's privacy controls and policies.
For information directly handled by EXO, you can contact us using the email address provided in Section 15.
Paper Fold: Learn & Craft is an educational and creative application.
The App does not require users to create accounts or directly provide personal information to use its core features.
Because the App uses Google AdMob, advertising-related information may be processed by Google.
Where required by applicable law, appropriate safeguards, consent mechanisms, and advertising settings are applied for children and users under the applicable age.
If you believe that a child has provided personal information directly to us, please contact us. We will take appropriate action in accordance with applicable laws.
The App does not provide user accounts, so there is no account that needs to be deleted.
To remove locally stored App data, you can delete the App from your iPhone or iPad.
You can generally delete the App by:
Pressing and holding the App icon.
Selecting Remove App.
Selecting Delete App.
Information processed by third-party services such as Google AdMob is subject to Google's own privacy policies and privacy controls.
If you believe that EXO directly holds personal information about you and would like to request its deletion, you may contact us using the email address provided in Section 15.
The core functionality of Paper Fold: Learn & Craft does not require access to:
Camera
Microphone
Location
Contacts
Phone
Messages
Health data
The App may use standard iOS system functionality required to operate the application and display advertisements.
If future versions of the App require additional permissions or access to personal information, this Privacy Policy will be updated accordingly.
We may update this Privacy Policy from time to time as the App, third-party services, or applicable laws change.
Any material changes will be reflected by updating the "Last updated" date at the top of this Privacy Policy.
We encourage users to periodically review this Privacy Policy for the latest information about our privacy practices.
