Every row and column has been eliminated.
When signed in, Multiply saves and updates a single spreadsheet named Multiply_Scores.csv directly inside your own Google Drive using Google's non-sensitive drive.file scope. Each run is labeled sequentially by Player Handle (Beth 1, Beth 2, Sam 1) along with the grid size, scramble mode, date, time, and elapsed seconds—ready to open in Google Sheets.
If DEFAULT_GOOGLE_CLIENT_ID is not yet hardcoded in index.html, paste your Google Cloud Web Application OAuth Client ID below (e.g., 123456-abc.apps.googleusercontent.com) with Authorized Redirect URI set to https://wdv.com/multiply:
Warren Design Vision (wdv.com) collects, transmits, processes, and stores ZERO bytes of personal data, student names, OAuth tokens, or score records on its servers. By default (Tier 1 Walk-Up Mode), https://wdv.com/multiply/ runs 100% inside volatile browser RAM and writes nothing to local disk so shared classroom computers never expose one student's scores to another. When a user or educator chooses Tier 2 Google Drive Sync, the browser communicates directly with Google Drive's official REST API (drive.file scope) to read and write Multiply_Scores.csv exclusively inside that authenticated user's own personal Google Drive account.
The Player field is strictly for a first name, nickname, or short classroom station handle (e.g., Beth, Sam, Station 3), which the app automatically indexes as Beth 1, Beth 2, Sam 1. Users, parents, and educators must never enter full legal names, email addresses, birthdates, or school ID numbers into the Player handle box. Any user or educator who connects their Google Drive acts as the sole, independent Data Controller of their own Google Drive files.
