Set target ratings for each format. The dashboard goal bar and trajectory will use these targets.

Select which formats to track. Unchecked formats are hidden from goal bars, rating trajectory, and stats. Classical is excluded by default.

How many minutes can you train per day? The training plan will limit today's tasks to fit this window.

Tell the coach which openings you actually play. ECO codes are authoritative — the coach uses these to know whether a game is "in repertoire" and stops penalising stylistic choices within your openings. Comma-separated; ranges OK (e.g. D01, B10-B19).

Choose how chess positions render in Repertoire Drills, Position Drills, and other in-app boards. Preference saves automatically.

Engine analysis runs on your VPS in the background. New games auto-queue when imported; the VPS picks them up within ~30 seconds and writes complete eval data back to Supabase. If you ever want to re-analyse the entire library (after engine upgrades, to fix stale data, or just for peace of mind), use the button below.

When Lichess cloud-eval doesn't have a position (returns 404), the app can fall back to a local Stockfish engine running in a Web Worker. This requires self-hosting two files on your domain — CDN-based loading proved unreliable across browsers and we got tired of chasing it. With Stockfish self-hosted, coverage approaches 100% for any game. Without it, the app uses Lichess cloud-eval + the "request Lichess analysis" prompt, which is the reliable path most users actually need.

Tune what counts as a drift moment. Stricter values = fewer but higher-quality drill positions. Adjustments apply immediately to the Position Drills library — entries that no longer meet the thresholds are hidden (not deleted) and reappear if you loosen the values back.

Maps each coaching theme to a Lichess puzzle theme. Consumed by the upcoming smart-daily-plan puzzle rotation (v25.6 Phase 4) — when surfacing puzzles that match the patterns in your last 15 coached games, the rotation looks up the Lichess theme via this table. Leave a field blank for themes with no good Lichess equivalent; the rotation skips those. Multiple themes per row are allowed — separate with commas (e.g. fork, advantage) and the rotation will treat them as a candidate set. Valid Lichess theme strings: see lichess.org/training/themes. Changes save on each field edit; reload not required.
