Privacy policy

Last updated 27 August 2026

The short version: Luasc has no accounts and no ads. Your matches live on your devices and, if you're signed in to iCloud, in your own private iCloud database. The app sends your match data to no servers of ours, and we never see it.

What Luasc stores

• Match data: scores, formats, point timelines, and the player names you enter. Stored on your iPhone.
• Presets and settings: your saved game types, player profile and match defaults.
• Player directory: names of people you've played with or against, so you can pick them from a list instead of retyping them.

This data syncs between your own devices through your private iCloud database (Apple CloudKit). It's readable only by you, under your Apple ID. Not by us, and not by anyone else. If you're not signed in to iCloud, everything simply stays on the device.

Health data

When you score from your Apple Watch, the session is recorded as a tennis workout, with heart rate, distance and energy, using Apple HealthKit, only after you grant permission. Workout data is written to Apple Health and governed by Apple's Health privacy protections. Luasc never transmits your health data anywhere.

Location

“Remember where I play” is off by default. If you turn it on, the watch captures a single location fix at the start of the match, never continuous tracking, so your match history can show where you played. To turn the coordinates into a venue name, your iPhone uses Apple's geocoding service, which involves sending the coordinates to Apple; this is the standard iOS reverse-geocoding lookup and includes nothing about you or the match.

Spoken scores

Score announcements are generated on-device with Apple's speech synthesis. Nothing is sent anywhere.

Purchases

Luasc Pro is an optional in-app purchase. Payment is handled entirely by Apple through the App Store. Luasc never sees your card or payment details. All the app keeps is whether Pro is currently active, and it confirms that with the App Store on each device you use. There's no account and no separate profile tied to your purchase.

Usage analytics in the app

Luasc uses TelemetryDeck to understand which features actually get used: for example, whether a match was started on the watch or the phone, whether it was finished, or whether someone tapped through to the Pro paywall. Like Plausible below, TelemetryDeck is anonymous and cookie-free: it identifies devices with a salted, one-way hash that can't be reversed back to you, sets no cookies, and never uses Apple's ad-tracking framework. What it sends is a feature name and a small number of non-identifying details (a match format, which screen prompted an upgrade, an error code). Never your name, your opponents' names, your score, or your match location. That data isn't linked to your identity and is never sold.

This website

The pages on luasc.com, separately from the app, use Plausible Analytics to count visits and see which pages people actually find useful. Plausible is cookie-free: it sets no cookies, collects no personal data, doesn't follow you across other sites and doesn't build a profile of you. What it produces is aggregate counts about pages, not about people. This applies to the website only; browsing here has nothing to do with what the app does on your devices.

The “Download on the App Store” links here, the luasc.com/get address printed on a shared match card, and the link in the Luasc Instagram bio all carry a campaign tag in the URL that tells Apple which of them the tap came from. It identifies the link, not you: App Store Connect reports it back as a count of downloads per source, and only once at least five different people have installed from that source, with nothing about who any of them are. No third party is involved and nothing is added to your device.

What the app doesn't do

• No accounts or sign-up.
• No advertising or ad SDKs, and there never will be.
• No selling of your match data.

Luasc talks to no third-party services apart from Apple's (iCloud, Health, geocoding) and TelemetryDeck (anonymous usage analytics, described above). Nothing else, under your own Apple ID or otherwise. This describes the app as it ships today, not every future version. If a later release changes what it collects, this page changes with it, and so does the “last updated” date above.

Deleting your data

Delete matches from the Stats tab, or delete the app to remove everything on the device. Data synced to iCloud lives in your private iCloud database and can be removed by deleting the app's iCloud data from iOS Settings → Apple ID → iCloud.
