Welcome to NDU Studio. Your privacy is our top priority. This Privacy Policy explains how we collect, use, and protect your information when you use our mobile applications and our website (www.ndustudio.com).
We believe in transparency. Depending on the app you use, we may collect the following types of information:
Personal Data: We do not collect personal identification information (like name or address) unless you voluntarily provide it by contacting us via email.
Usage Data: We may collect non-personal information such as device type, operating system, and app usage statistics to improve our services.
Media and Files (For Vault Apps): For apps like Calc Vault Pro, all photos, videos, and files are stored locally on your device. We do not have access to your private files, nor do we upload them to any external servers.
Our apps may request specific permissions to function correctly:
Camera: To capture images for the "Intruder Selfie" feature in our vault apps.
Storage: To hide and secure your files on your device.
Biometrics/Fingerprint: To provide secure local access to your encrypted vault.
We take data security very seriously.
All data processed by our utility and vault apps is encrypted and stored offline on the user's device.
We do not use cloud storage for your private content, ensuring that you have 100% control over your data.
We may use third-party tools (like Google AdMob or Firebase Analytics) to show ads or analyze app performance. These third parties may collect information sent by your device as part of their service, governed by their own privacy policies.
Our services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.
We may update our Privacy Policy from time to time. We notify you of any changes by posting the new Privacy Policy on this page.
