This Privacy Policy describes how PT. Devora Digital Kreasi ("we", "us", or "our") collects, uses, and discloses your information when you use the Concrete Calculator App (the "App").
Our App is designed to perform calculations locally on your device. We prioritize your privacy and do not collect any personal data on our servers.
All calculation history, project names, and customer details you enter are stored locally on your device using encrypted storage or shared preferences. This data remains on your device and is not uploaded to any external cloud service or server.
If you use the feature to upload a company logo for your PDF invoices, the App will require access to your device's photo gallery. These images are stored locally on your device and are used solely for generating your PDF documents.
To provide its full functionality, the App may request the following permissions:
Since all data is stored locally on your device, the security of your data depends on the security of your mobile device. We recommend using device-level security (PIN, pattern, or biometric) to protect your information.
The App does not use any third-party analytics, tracking, or advertising services that collect user data.
Our App does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children.
We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
