Log matches. See what's working.

Game Set Log is a match-tracking and stats app for tennis players who want more than a scoresheet, without a subscription, an account, or a cloud connection. This is the **Offline Version** — a single downloadable file with no license check and no server connection at all, ever. It's yours to keep and use however you like.

**What it does:**

• Log singles and doubles matches — opponent, partner, score, and notes in a couple of taps
• Track serve and error stats: aces, double faults, return errors, net errors, hit wide, change of direction, plus-one errors
• Correct tiebreak handling — only the deciding set's tiebreak counts as a tiebreak win, not every 7-6 set
• Handles retirements, walkovers, and no-result matches properly, excluded from your win % and streaks where they should be
• See trends over time — by week, by league or tournament, by opponent, by surface
• Rename or merge league/tournament names across every match at once, so a typo doesn't split your history
• Export your data as JSON (full backup/restore) or CSV (spreadsheet-ready)

**What it isn't:**

• No account, no login, no cloud sync
• No ads, ever
• No subscription — pay once, use forever

**How your data works:**

Everything lives in your browser's local storage, on your own device. We never see it, store it, or have access to it. Because it's local-only, moving to a new device means exporting a backup first — there's no automatic sync by design. Use the built-in Export/Import to move your data yourself, any time.

**Format:** One self-contained HTML file. Open it in any modern browser — nothing to install, nothing to configure. Works on iPad, desktop, and mobile browsers.

**Purchase type:** One-time purchase. Refunds handled no-questions-asked within 14 days.
