Privacy Policy
Established: 15 June 2026
CuViu (“we”) sets out below how we handle personal information. This policy covers our website (cuviu.jp), the iOS / watchOS app MatchHub (Japanese title: 卓球MatchHub) and the web app Scorebook by CuViu.
MatchHub (iOS / watchOS app)
Your match records, player information and settings are stored only on your device. They are never sent to our servers.
- No account and no sign-in are required
- Your records leave the device only when you export them yourself
- The app uses no analytics tools
Ads (version 1.1.1 and later)
MatchHub shows Google AdMob banner ads on the settings screen and the history screen. No ads are shown on the scoreboard during a match, and none on Apple Watch.
- To deliver ads and measure them, Google and its advertising partners may collect and use device identifiers (such as the advertising identifier), your IP address and information about how the app is used
- What is collected, and what it is used for, follows Google’s “How Google uses information from sites or apps that use our services” (https://policies.google.com/technologies/partner-sites)
- Where consent is required (for example in the United Kingdom, Switzerland and Norway), the app asks for your consent, and you can change it at any time from “Privacy settings” on the settings screen
- After you first open the app, iOS asks whether MatchHub may track you across other companies’ apps and websites. Only if you allow it can ads be chosen for you with the advertising identifier. You can change this at any time in Settings > Privacy & Security > Tracking
- Your match records, player information and notes are never sent for advertising
Scorebook by CuViu (web app)
Scorebook by CuViu (https://cuviu.jp/apps/scorebook/) is a baseball scorebook that runs in your browser.
- Your game records and what you enter, such as player and team names, are stored in your browser. They are not sent to our servers, except when you use “Send feedback” below
- When you use “Send feedback”, your message, the game you have open (including player names) and a screenshot are saved on our server and emailed to us. We use them only to look into your feedback and improve the app
- A team share URL contains the team roster, such as player names. The roster lives in the URL and is not stored on our servers. Anyone who receives the URL can see the roster, so take care whom you share it with
- Support payments are made on a page run by the payment service Stripe. Your card number is handled by Stripe and never reaches us. Through Stripe we receive your email address and a record of the payment (see “2. The personal information we collect”)
- Pages on cuviu.jp may show ads from Google AdSense. Scorebook by CuViu does not show ads. (see “5. Cookies”)
- We use Google Analytics to understand how the app is used (see “6. Analytics”). What you enter, such as player names, and the roster in a team share URL are not sent
Everything from “1. Who we are” onwards is about our website (cuviu.jp, including Scorebook by CuViu). It does not apply to MatchHub.
