Privacy Policy
In short: Qadrixa does not collect, sell or share any personal data. There is no account, no advertising and no analytics. Your projects stay on your device. The only connection is the Google Play purchase of Qadrixa Pro, which Google Play handles.
Who we are
Qadrixa (package name com.carlofabon.qadrixa) is a 3D CAD app made by an independent developer in the Philippines and published on Google Play under the developer name shown on its Google Play page (“we”, “us”). This policy explains how the app handles information on your device.
Information we collect
We do not collect any personal information. The app does not send your projects, files, contacts, location, device identifiers, usage data or crash reports to us or to anyone else. The app contains no advertising, analytics or tracking software, and it makes no network requests of its own.
Information stored on your device
To work, Qadrixa keeps the following on your device only:
- An automatic save of the project you are working on, so it can be recovered the next time you open the app.
- Your preferences, whether you have seen the quick tour, and whether Qadrixa Pro is unlocked.
Projects you save (.qdx) and files you export are written only to the place you choose. Files you open are read only with the access you grant at that moment through Android’s file picker.
Permissions and why they are used
| Permission | What it is used for |
|---|---|
| Google Play billing | To buy and restore Qadrixa Pro, a one-time in-app purchase that unlocks exporting. |
| Internet, network state | Added by the Google Play Billing Library so Google Play can process and confirm the Qadrixa Pro purchase. Qadrixa itself does not contact any server. |
Qadrixa does not ask for storage, camera, microphone, location or contacts permissions. Opening and saving files goes through Android’s file picker, which needs no permission.
Payments
Qadrixa is free to download. Qadrixa Pro is sold through Google Play, and Google Play handles the purchase and payment. We never receive or store your payment details. The app only asks Google Play whether Qadrixa Pro was bought on your Google account, and keeps that answer on your device so exporting also works offline.
Sharing of information
We do not share, sell or transfer any information, because we do not collect any. When you export a part or a drawing, the file is saved where you choose; sharing it is up to you.
Third-party services
Qadrixa is distributed through Google Play. Google may collect information when you download or update apps, or buy in-app products, as described in Google’s Privacy Policy. Qadrixa itself does not include third-party advertising, analytics or crash reporting services.
Children
Qadrixa is suitable for all ages. Because the app collects no personal information, it does not collect personal information from children.
Data retention and deletion
All data stays on your device. To delete it, clear Qadrixa’s storage in Android’s app settings, or uninstall Qadrixa, which removes its automatic save and preferences from your device. Projects and exports you saved elsewhere are removed by deleting those files. A Qadrixa Pro purchase stays on your Google account and can be restored after you reinstall.
Security
Qadrixa keeps its data in the app’s private storage on your device. No method of storage is completely secure, but because nothing is sent to us, your information stays under your control.
Changes to this policy
If we change this policy, we will update this page and the effective date above. Significant changes will also be noted in the app’s update notes on Google Play.
