Carpenter Calculator
This policy explains how information is handled when you use Carpenter Calculator (formerly JS Universal Calculator), published by JS Universal Technologies (OPC) Private Limited.
Last updated: 21 October 2026Information you provide
The app processes measurements, project details, saved calculations, shopping-list entries, scanned documents and photos, app settings, and any business profile details you choose to enter (such as business name, phone number, address or GST number). This information is stored on your device. The developer does not operate servers for this data and cannot access it.
Device storage and permissions
The camera, document scanner and file access are requested only when you use features that need them, such as scanning a document or exporting a file. Photos scanned in the app are also saved in a separate album named "Carpenter Calculator" in your phone Gallery, so they are not lost if the app is removed. These files stay on your device and you can delete them anytime from your Gallery. The app does not access your other photos; it only uses photos you choose to add as a page. Internet access is used for advertising and for the optional Google Account backup.
Sharing and data control
Information is not sold as personal data. When you share a report, PDF, image or backup file, the app you select (for example Gmail, WhatsApp or Google Drive) handles it under its own terms and privacy policy. Nothing is shared unless you start it. You can delete saved records inside the app at any time. Data stored on your device stays until you delete it in the app or uninstall the app (scanned photos in the Gallery album remain until you delete them). Because the developer does not hold your data on its own servers, there is nothing for us to delete on your behalf; contact us below for any request. The app is a general utility tool and is not directed at children under 13. If this policy changes, this page and its "last updated" date will be updated.
Advertising and third-party services
Carpenter Calculator may display advertisements using Google Mobile Ads. Google and its advertising partners may process certain device and advertising-related information, such as device identifiers, IP address, app interactions, diagnostics and advertising data, in accordance with their own privacy policies and applicable consent settings. The application may also use third-party services required for features such as document scanning, file sharing, web content and other app functionality. Information handled by these services is subject to their respective privacy policies. Carpenter Calculator does not intentionally sell users' personal information.
Optional Google Account backup
You may choose to connect your Google Account in the app (Backup & Restore) to back up your data. The backup contains your saved records, settings and scanned photos, and is stored in the private "App Data" area of your own Google Drive. This area is hidden from your normal Drive view and can be read only by this app with your permission; the developer cannot see or access your backup. The app requests only the Google Drive "App Data" permission (drive.appdata) and cannot see your other Drive files. Your Google name, email address and profile picture are not sent to or stored by the developer; the email address may be shown on the Backup screen so you know which account is connected. If you turn on automatic backup, the app uploads a new backup about once a day when you open it. You can turn it off, tap Disconnect in the app, or remove the app's access in your Google Account settings at any time, and you can delete the backup from Google Drive (Settings > Manage apps). On a new phone you can connect the same account and restore your data. Google processes this data under the Google Privacy Policy.
