Privacy and learning records

No account, name, email or microphone recording is required. Answers, written drafts, progress and explanation language stay in this browser; the learning app does not send them to a server.

Our own statistics count daily distinct browsers per site, public page views, foreground time and lesson interactions. A site-only temporary cookie named labs3001_daily expires at midnight in Korea (UTC+9). The statistics server keeps only hashes used for same-day deduplication; cleanup runs every 30 seconds after the date changes. Aggregate totals are kept for 90 days. The 7-day and 30-day visitor figures are sums of daily counts. We do not link dates, sites, devices or accounts. The statistics store does not keep IP addresses, search terms, answers, scores, progress or written content. Hidden tabs and unfocused windows are excluded from active time. Existing opt-outs and browser GPC/DNT signals are respected. Browsers blocking the cookie are excluded from distinct visitor counts. Earlier identifier-based records expire under their existing retention schedule and are not linked to the new totals. Server access logs, login and learning records, advertising and Google privacy choices remain separate.
