ETC Toll ZIP-to-PDF – Privacy Policy

Last updated:

Summary

  • All processing (ZIP scan, hashing, PDF merge) happens locally in your browser tab/worker; no network requests are made.
  • Your ZIP/PDF files stay on your device. They are used only to discover valid directories, deduplicate by hash, and merge PDFs for download.
  • No analytics, tracking, or third-party sharing. No personal identifiers are collected.
  • Optional preferences may be stored in chrome.storage; temporary data (buffers/ObjectURLs) is cleared when you close the tab or click clear/cancel.
  • Closing the extension tab immediately stops processing and frees temporary resources.

Data We Handle

  • Uploaded files: up to 10 top-level ZIP files per run, including contained PDFs and nested ZIPs.
  • Derived data in memory: directory names, ZIP entry paths, SHA-256 hashes of apply.zip/detail.zip for deduplication, and generated merged PDFs.
  • Optional preferences: UI language choice (via Chrome UI language), optional toggles, and any future local settings.

How Data Is Used

  • Files are read locally to find valid directories (must contain apply.zip and detail.zip), guard against abnormal entry counts, and warn on missing/damaged content.
  • Hashes are computed locally to skip duplicate directories with identical content; different content is processed separately.
  • Collected PDFs are merged locally into a single PDF per directory and exposed via URL.createObjectURL for you to click/download.
  • Progress and logs are shown only in the UI; they are not sent anywhere.

Storage & Retention

  • Processing buffers and ObjectURLs live in memory for the current tab session; cleared on cancel/clear or when the tab closes.
  • Optional preferences may be stored locally in chrome.storage (no remote storage). You can clear them via the UI or Chrome settings.
  • Generated PDFs are downloaded to your device according to your Chrome download settings; no server copy exists.

Transmission

  • No network requests are made by the extension for processing. Everything stays on your machine.

Consent & Control

  • Data is processed only after you select/upload ZIP files and click start.
  • You can cancel at any time; closing the tab stops processing and clears temporary data.
  • You can clear results/logs/ObjectURLs via the UI clear action.

Single Purpose

  • Purpose: merge ETC toll invoice PDFs from structured ZIP files locally for your download.
