Download Exam Attendance Sheet at Once. # BRACU Exam AttendSheet Saver **BRACU Exam AttendSheet Saver** is a Chrome extension for downloading exam attendance sheets from the BRAC University Connect portal. It automates repetitive section-by-section downloads and can combine the resulting PDFs into a single attendance document. ## Overview The extension provides a focused workflow around the BRACU Exam Attendance Sheet Download page: - Opens the BRACU attendance-sheet portal directly from the extension. - Verifies that the correct Attendance Sheet Download page is active before exposing download controls. - Reads the available section options from the portal. - Downloads attendance sheets for all sections or for a user-defined section range. - Supports section identifiers such as `1`, `24`, `01`, `01A`, and `01B`. - Sorts section identifiers naturally so that values such as `01A`, `01B`, `02A`, and `02B` are processed in the expected order. - Saves individual attendance sheets using section-based filenames such as `S01A.pdf`. - Optionally merges the downloaded PDFs into one course-level PDF. - Optionally adds a blank page after a single-page attendance PDF during merging. - Shows download and merge progress inside the side panel. ## Workflow 1. Open the extension side panel. 2. Select **OPEN PORTAL**. 3. Open or authenticate to BRACU Connect if required. 4. Navigate to the **Exam Attendance Sheet Download** page. 5. After the page is verified, **DOWNLOAD SETTINGS** becomes available. 6. Choose a section mode: - **Select All** — processes every available portal section. - **Manual Input** — specify a From and To value. 7. Review the selected sections shown after starting the download. 8. Choose whether PDFs should be merged and whether blank pages should be added to single-page PDFs. 9. Select **START DOWNLOAD**. 10. Monitor the progress panel until the individual downloads and optional merge are complete. ## Section Selection ### Select All The extension reads the section list directly from the portal and sorts it naturally before processing. This prevents alphabetical ordering problems such as `10A` appearing before `2A`. ### Manual Input Manual Input uses two text fields: - **From** — defaults to `1`. - **To** — defaults to `24`. The fields accept values such as: ```text 1 01 01A 01B 24 ``` Numeric endpoints are interpreted by section number. For example, when the portal provides `01A`, `01B`, `02A`, and `02B`, a numeric range covering sections 1 through 2 includes those available subsections. Alphanumeric endpoints can also be used directly, allowing ranges such as `01A` through `05B` when those sections exist on the portal. A maximum of 200 sections can be processed in a single run. ## PDF Download and Processing The extension uses Chrome's download facilities for the individual attendance PDFs. For merging, it captures the PDF response associated with the portal's original download request and processes the PDF data in the extension's background service worker. It does not need to download the same PDF a second time just to perform the merge. When merging is enabled, the final file is named using the selected course code: ```text COURSECODE_Attendance_Merged.pdf ``` For example: ```text CSE101_Attendance_Merged.pdf ``` Individual section files are saved with section-based names, for example: ```text S01A.pdf S01B.pdf S02A.pdf ``` Chrome's normal filename conflict handling is retained, so existing files are not silently overwritten. ## Progress and Run State The side panel provides: - Total section count. - Completed section count. - Overall download progress. - Current section status. - Individual success and failure messages. - PDF merge progress. - Final merge status. - A persistent completion log for the current run. After a run finishes, the download settings are restored for a new run while the completed progress information remains visible. ## Privacy and Data Handling Privacy is a core design requirement of this extension. ### No tracking or analytics The extension does **not** track users. It does not contain analytics, advertising, telemetry, user profiling, or third-party tracking services. ### No external data collection The extension does not send attendance sheets, student information, course information, section information, or downloaded PDF contents to an external server. There is no remote database or developer-controlled data collection service in the extension. ### Local processing The information required to perform a download is processed locally by the extension and the user's browser. PDF merging is performed locally in the extension rather than by uploading the documents to an online PDF service. ### Portal access is functional, not tracking The extension does need access to the BRACU Connect attendance-sheet page because it has to interact with the portal, read the available sections, initiate the requested downloads, and obtain the PDF data required for local processing. This access is used only to provide the extension's stated functionality. ### No Downloads-folder browsing The extension does not scan or browse the user's Downloads folder. It uses Chrome's download API to create the files generated by the extension. ### No unrelated website access The declared website access is limited to the BRACU Connect domain used by the attendance-sheet workflow. The extension does not intentionally operate on unrelated websites. ## Permissions The extension requests the following Chrome permissions because they are required by its implementation: | Permission | Purpose | |---|---| | `sidePanel` | Provides the extension's side-panel interface. | | `downloads` | Creates and monitors the attendance-sheet PDF downloads and the final merged PDF. | | `debugger` | Captures the original PDF network response so the PDF can be merged locally without downloading the document a second time. | | BRACU Connect host access | Allows the content script to interact with the BRACU attendance-sheet page. | The `debugger` permission causes Chrome to display a broad permission warning. This wording is generated by Chrome for the permission and is not an indication that the extension is collecting or transmitting user data. Chrome's current permission documentation lists `debugger` as triggering the warnings **“Access the page debugger backend”** and **“Read and change all your data on all websites.”** The extension uses the permission for its PDF-capture workflow and does not use it for browsing-history collection, analytics, advertising, or unrelated website activity. ### User-Controlled Site Access Chrome allows users to control an extension's **website access** from the extension management page. In Chrome, open **Extensions → Manage extensions → BRACU Exam AttendSheet Saver → Details**. Under the extension's site-access controls, users can choose whether the extension can access the current site when selected, automatically access specific sites, or access all sites. Users can also add or remove allowed sites when Chrome provides the **On specific sites** option. For this extension, the intended website access is the BRACU Connect domain used by the attendance-sheet workflow. Restricting or removing that site access can prevent the extension from interacting with the BRACU attendance page and therefore can prevent downloads or portal automation from working. These Chrome controls apply to website access. They do **not** mean that every manifest permission can be individually switched off from the Details page. Permissions such as `downloads`, `sidePanel`, and `debugger` are part of the extension implementation; Chrome determines how those permissions are granted and presented. For official Chrome instructions on managing extension site access, see the Chrome Help documentation: https://support.google.com/chrome/answer/2664769 ## Security and Scope The extension is designed around the specific BRACU attendance-sheet workflow rather than general web automation. Its content script is declared for the BRACU Connect domain, and the download process is initiated by the user from the extension side panel. The extension does not ask for account passwords, does not provide a separate login system, and does not transmit BRACU credentials to the developer. ## Project Structure ```text manifest.json Chrome extension manifest background.js Download orchestration, PDF capture, state, and merging content.js BRACU portal interaction and section selection sidepanel.html Side-panel structure sidepanel.css Side-panel styling sidepanel.js Side-panel controls and progress rendering icon16.png Toolbar icon icon48.png Extension icon icon128.png Large extension icon README.md Project documentation ``` ## Notes - The extension is intended for the BRACU Connect Exam Attendance Sheet Download workflow. - The portal must be accessible and the required course/section options must be available for a download to succeed. - Network or portal-side changes can affect automation behavior. - The extension does not bypass BRACU authentication; users remain responsible for their own authenticated portal session. ## Attribution © Samiur Rahman
