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 **Web/PWA Version** — the same complete app as the Offline Version, plus a one-time license check on first use and the ability to install it to your home screen like a native app. Once verified, it works fully offline too.

**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 you get over the Offline Version:**

• Install to your home screen for one-tap access, like a native app
• Automatic updates whenever we improve the app — no re-downloading a new file
• Same one-time license, checked once on your device, then works fully offline from then on

**What it isn't:**

• No account beyond the one-time license check, no ongoing login
• 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 — never sent to us, license check aside. We never see, store, or access your match data. 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:** Installable Progressive Web App (PWA). Works on iPad, desktop, and mobile browsers.

**Purchase type:** One-time purchase, not a subscription. Refunds handled no-questions-asked within 14 days.
