Privacy policy
Effective 16 October 2026 · App: DWG Viewer (com.cadreader.dwgviewer) for Android
Your drawings
Drawings and models you open are read and shown on your device only. DWG Viewer keeps a copy in the app's private storage so you can open them again from Recent and Favorites. They are never uploaded to us or to anyone else. Exports (PNG, PDF, DXF) are written where you choose or handed to the app you share them with. Removing a drawing from the list, clearing recent drawings or uninstalling the app deletes these copies.
Ads
The free version shows ads from Google AdMob and Unity Ads. To show and measure ads, these networks collect your device's advertising ID, approximate location from your IP address, device and app information, and how you interact with ads. In the European Economic Area, the UK and Switzerland, and where else the law requires it, the app asks for your consent with Google's User Messaging Platform before ads are personalised; you can change your choice in Settings → Privacy choices. You can reset or delete your advertising ID in Android Settings → Google → Ads. See how Google uses information from apps that use its services and the Unity Ads privacy policy. DWG Viewer Pro shows no ads.
Purchases
DWG Viewer Pro is bought through Google Play Billing. Google handles the payment; the app only learns whether you have an active Pro purchase. We never see your card or payment details. Manage or cancel subscriptions in Google Play → Payments & subscriptions.
Analytics and crash reports
The app uses Google Firebase Analytics and Firebase Crashlytics to count how features are used (for example "a drawing was opened" or "a PNG was exported", with the file format but never the file name or content) and to receive crash reports with the device model, Android version and the app's state at the time of a crash. Firebase Analytics is not linked to your advertising ID. Google keeps it for a limited time under the project's retention settings.
Permissions
- Internet: to load ads, check purchases and send analytics and crash reports. Opening drawings needs no network.
- Advertising ID (AD_ID): used by the ad networks as described above.
- Billing: for Google Play purchases.
DWG Viewer does not ask for access to your files, camera, contacts or location; you pick each drawing yourself with Android's file picker or share it to the app.
Children
DWG Viewer is meant for people aged 13 and over and is not directed at children.
Sharing
We do not sell personal data. Data is shared only with the service providers named above (Google AdMob, Unity Ads, Google Firebase, Google Play) for the purposes described.
Deleting your data
Clear the app's storage or uninstall it to remove every drawing and setting. To ask us about analytics data linked to your device, write to us; we answer within 30 days.
Changes and contact
If this policy changes, the new version will be posted here with a new date. Questions: fighttech.vn@gmail.com.
