ZetaLog

ZetaLog records every game you play on Zetamac (arithmetic.zetamac.com) and turns your history into a clear picture of how you are improving. No copying scores into a spreadsheet, no manual logging. FEATURES • Automatic score capture. Play Zetamac as usual and ZetaLog records the result the moment a game ends. • Progress over time. A trend that adapts to your history: a recent-scores list, then a sparkline, then a full chart as you play more. • Personal bests. Your best score at each standard duration (30s, 60s, 120s) for the default settings. • Skill analysis. Your solve times broken down by operation and times table, with the specific problems that slow you down. • Works offline. Everything runs on your device and the extension is fully functional without an account. An otherwise eligible game played offline is considered for ranking when it later syncs. • Optional leaderboard. Link a ZetaLog account to compare your best scores worldwide, with a per-university board if you verify a UK student email. Submitted telemetry is recomputed and checked for consistency; suspicious scores can be held for review. HOW TO USE 1. Install ZetaLog and play a round at arithmetic.zetamac.com. 2. Click the ZetaLog toolbar icon to see your latest score, personal bests and trend. 3. Optional: press Sync to leaderboard, sign in on the ZetaLog site and link the extension to start syncing your best scores. PRIVACY ZetaLog stores your game history on your own device. Nothing is uploaded unless you link an account, and even then only your game results are sent, never your browsing. Full details are in the privacy policy linked below. PERMISSIONS • Storage. Saves your recorded games, preferences and (if you link an account) a revocable extension credential on your device. • Unlimited storage. Prevents Chrome’s normal local quota from discarding legitimate scores or pending offline game evidence as your history grows. • Alarms. Schedules background retries so that, when leaderboard sync is on, a score that failed to upload is retried later. • Identity. Opens a secure, browser-owned account-link redirect after one explicit Link click; it carries no Chrome install warning. • Access to arithmetic.zetamac.com. Reads the running game (problems, answers, score, timer) to record your result. This is the core feature and the only site ZetaLog reads. • Access to the ZetaLog link page (www.zetalog.co.uk/link). Receives only your explicit request to start the browser-owned link flow; credentials, website session tokens, authorization codes, and the PKCE verifier are never exposed to the page or content script. Requires Chrome 116 or later. ZetaLog is an independent project and is not affiliated with Zetamac. SUPPORT Questions or bugs: contact.mtaha@gmail.com
