This Privacy Policy describes how European Castle Heritage Guide developed by MyEdhulight- AzxMatrix ("we," "our," or "us") collects, uses, and protects information when you use our mobile application European Castle Heritage Guide ("the App") and our companion website. We are committed to safeguarding your privacy and being transparent about our data practices.
Your privacy matters to us. This policy explains what information we collect, why we collect it, and how you can control it. The App is an offline guide to medieval castles across Europe, featuring castle profiles, travel routes, budget tips, and a personal photo diary.
When you use the App, the following information is collected automatically:
The App generates a unique anonymous identifier on your device when you first launch it. This identifier does not contain any personally identifiable information and is used solely to understand app usage patterns. It persists on your device until you clear the app data or uninstall the App.
The App detects your device's language and region settings to provide relevant content.
The App collects your device's Google Advertising ID for attribution purposes — to understand how users discover and install the App. You can reset your Advertising ID or opt out of ad personalization at any time in your Android device settings under Settings > Google > Ads. Learn more about Google advertising policies.
The App uses AppsFlyer for mobile attribution and marketing analytics. The following data is collected to understand how users discover the App:
Your anonymous user identifier, Advertising ID, and attribution data are shared with AppsFlyer. AppsFlyer also collects additional device data (such as IP address, device model, and operating system version) as part of its standard operation. For full details, see AppsFlyer's Privacy Policy.
The App includes a built-in browser used to display this Privacy Policy and the Support page directly within the App. The built-in browser does not collect any additional data beyond what is described in the Automatically Collected Information section above. The built-in browser supports cookies (including third-party cookies) and local storage as part of standard browser behavior. Any websites loaded in the built-in browser operate under their own privacy practices.
The App includes a photo diary feature that lets you capture and store photos of castles you visit. When you use this feature:
The App stores the following data locally on your device:
This data is not transmitted to our servers unless explicitly stated. You can clear all locally stored data through your device settings or by uninstalling the App.
The App downloads display fonts from Google Fonts when first launched. This requires a network connection and involves a request to Google's servers. For details on how Google handles this data, see Google's Privacy Policy.
The App's Support page allows you to send us a message or report a bug. When you submit a support request, you may provide:
This information is submitted only when you choose to send a support request. We use it solely to respond to your inquiry and resolve the reported issue. The App itself does not access your camera directly — photo and video capture is handled entirely by your device's built-in camera app.
We use the collected information for the following purposes:
We do not sell your personal information. We share data with the following third-party services:
We may also disclose information when required by law, regulation, or legal process.
We take reasonable measures to protect your information. Data transmitted between the App and external services uses encrypted connections (HTTPS). Some network connections within the App may use unencrypted HTTP. Locally stored data is protected by your device's security features.
You have the following options to control your data:
The App is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us and we will promptly delete it.
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy within the App. Changes are effective when they are posted.
