Privacy Policy

Scope of Data Collection

TraceCAD processes the files and settings needed to provide PDF conversion features. Depending on how you use the app, this may include selected PDF files, PDF page information, drawing geometry, rasterized page previews, OCR text candidates, conversion settings, diagnostic status, export status, credit balance information, purchase status, and exported DXF files.

The app does not collect your name, phone number, contacts, location information, or other personally identifiable information for advertising purposes.

Purpose of File Access

TraceCAD uses macOS file panels and App Sandbox permissions so you can choose the PDFs to open and the destinations where exported files should be saved. File access is used only for user-requested actions such as importing a PDF, rendering a preview, converting a drawing, and writing DXF output.

The app does not scan unrelated folders and does not access PDFs, DXF files, or other documents unless you choose them or choose an export destination.

Local Conversion and OCR

PDF rendering, vector extraction, image cleanup, OCR preview, OpenCV-based analysis, geometry reconstruction, DXF generation, and preview rendering run locally on your Mac in the current app workflow.

TraceCAD does not upload your source PDFs, drawing previews, OCR results, or generated DXF files to a TraceCAD server for conversion in the current local workflow.

Previews, Diagnostics, and Exports

The app may create temporary previews, conversion diagnostics, text overlays, and in-memory DXF text so you can inspect conversion quality before exporting. Exported DXF files are written only after you choose a save location.

If you export, copy, open, email, upload, or otherwise share PDFs, screenshots, previews, diagnostics, or DXF files yourself, that action is controlled by you and may be handled by the destination app or service you select.

Credits and Payments

TraceCAD uses consumable export credits for scanned PDF exports. Vector PDF exports may be free depending on the app version. Payments are handled by Apple through the App Store. TraceCAD may receive purchase and credit status needed to unlock paid features, but it does not receive or store your credit card information.

TraceCAD uses Firebase services to support anonymous app sessions, server-side purchase verification, credit balances, export spending, and refund adjustments. The Firebase-backed credit system may process a Firebase anonymous user identifier, authentication tokens, App Store transaction identifiers, product identifiers, signed transaction data needed for Apple verification, credit balance, credit ledger entries, export job identifiers, request timestamps, and server logs needed for security, reliability, fraud prevention, and support.

Your source PDFs, drawing previews, OCR results, and generated DXF files are not uploaded to Firebase for conversion or credit verification.

Data Storage and Use

App settings, recent conversion state, local diagnostics, Firebase authentication tokens, and related app data may be stored on your Mac. Server-side credit balances and credit ledger records may be stored in Firebase. Source PDFs and exported DXF files remain in the locations you choose.

TraceCAD does not sell your personal information and does not use your files, drawings, previews, OCR output, or DXF exports to train generalized artificial intelligence or machine learning models.

Data Sharing

TraceCAD does not sell your personal information. Data may be processed by Apple for App Store payments and by Google Firebase for authentication, Cloud Functions, Firestore credit records, security, reliability, and hosting operations. Data may also be shared only when needed to provide user-requested functionality, verify credits or purchases, comply with law, protect security, operate hosting infrastructure, or when you explicitly export, copy, open, upload, or share information yourself.

Data Deletion

You can delete exported DXF files and source PDFs from the locations where you stored them. You can remove locally stored app settings, Firebase authentication tokens, and local app data by deleting the app and its associated app container data from your Mac.

Payments, purchase history, and refunds are managed through your Apple ID and the App Store. Server-side credit ledger records may be retained as needed for purchase verification, fraud prevention, accounting, dispute handling, legal compliance, and support. To request deletion or review of server-side credit account data, contact us using the email address below.

Website Data

This privacy page may be hosted as a static website on GitHub Pages or similar static hosting infrastructure. Standard server logs or platform-level analytics may process basic request information such as IP address, browser, referring page, and request time for security, reliability, and hosting operations.

Policy Updates

This Privacy Policy may be updated due to app changes, export credit changes, payment changes, platform requirements, hosting changes, or legal requirements. Updated versions will be posted on this page.
