FAQ & troubleshooting

License and trial

How does the trial work? 7 days, every feature, up to 10 full game analyses per day. No account, no card. When it ends, nothing disappears — the app waits for a license to resume analyses.

How many Macs per license? Two. To change machines: deactivate the license on the old one from the license window, activate it on the new one.

I lost my license key. It’s in the purchase email. Can’t find it? A message to contact@regence.app is enough.

Can I get a refund? Yes — 30-day guarantee, full refund with no questions asked, with a single email.

Updates

How do updates work? Automatically: at launch, Régence offers the new version when one exists — one click installs. They’re included in the license, and the changelog is public.

Data

Where are my games and studies? On your Mac, in the app’s standard container. Settings > Storage opens the folder and exports a full backup.

How do I migrate to a new Mac? A backup exported from the old one, restored on the new — analyses included. Then deactivate/reactivate the license.

Does Régence send my games anywhere? No. Analysis runs locally; your games never leave your Mac. The only network requests: importing from Lichess/chess.com, theory lookups (explorer, position by position), license checks and updates. Full detail: privacy.

Analysis

Analysis is slow / my Mac is blowing air. That’s the Quiet / Performance setting: Quiet (default) favors silence, Performance speed. During a big batch, Performance + lid open remains the most effective.

A game shows “Waiting” and doesn’t move. The analysis queue processes one game at a time — Cmd + Shift + Q shows the run order. Analyzing the open game from the board puts it at the front.

Something went wrong and I want to report it. Help menu → “Export diagnostics…” saves a technical report: app version and recent events (engine starts, batch steps, positions that took too long, save errors). It contains no games, no accounts and no license keys, and nothing is sent automatically: you read it, then attach it to your message. “Contact support…”, in the same menu, opens the site’s contact form, with your version and system already filled in.
