Privacy Policy

Who we are

atDEUCE is a web-based padel session management tool operated by its developer. The service is available at atdeuce.com.

What data we collect

When you join a session as a player

• Display name — the name you type when joining via link or QR code. This is visible to the host and other players in the session.
• Session participation — which sessions you joined, your scores, and standings within those sessions.

No account is required to join and play. You can participate entirely anonymously.

When you sign in with Google

• Google profile — your name, email address, and profile picture as provided by Google OAuth.
• Session history — when you sign in, any sessions you previously joined anonymously are linked to your account so your history follows you.

Automatically

• Service analytics — we use Cloudflare Web Analytics for aggregate traffic data and PostHog for product analytics and diagnostics. Product events may include browser or session identifiers, user IDs, event IDs, format keys, counts, status values, and timing data. Our analytics event schema is designed to avoid names, email addresses, phone numbers, street addresses, avatar URLs, and event titles.

What we do not collect

• No advertising identifiers, ad-network pixels, or data sold to advertisers
• No payment or financial information
• No precise GPS location data
• No data from your Google account beyond name, email, and profile picture

How we use your data

• To run padel sessions — display names, scores, standings, and court assignments
• To authenticate you when you sign in with Google
• To link your anonymous session history to your account when you sign in
• To improve reliability and understand whether core flows are working

We do not sell, rent, or share your personal data with third parties for marketing purposes.

Cookies and local storage

atDEUCE uses a small number of cookies and browser storage entries to operate the service, remember preferences, and measure product reliability. No advertising cookies are used.

• Player session cookie (pp_participants) — maps your browser to the sessions you have joined. Expires after 30 days. Without this cookie, the app cannot identify you as a participant in a session.
• Auth verifier cookie — a short-lived, single-use cookie set during Google sign-in to complete the OAuth handshake. Consumed immediately and not persisted.
• Theme preference — stored in localStorage (not a cookie) to remember your light/dark theme choice.
• Analytics identity — PostHog may use cookies or browser storage to associate product events with the same browser session or signed-in user. This is used for product analytics and diagnostics, not advertising.

We do not add advertising or marketing cookies without updating this policy and any required consent handling.

Where your data is stored

Session data is stored in Convex (our real-time database provider). The application is served via Cloudflare Workers. Product analytics and diagnostics may be processed by PostHog. These services operate data centers globally or in their configured regions. Your data may be processed in any region where these providers operate.

Data retention

Session data (scores, standings, participation) is retained indefinitely so that hosts and players can review past sessions. Signed-in users can delete their account themselves from the Profile page (“Delete my account”): this removes your account and sign-in, and replaces your name on past events with “Removed player”. For anything else — or if you cannot sign in — contact us and we will remove it.

Your rights

If you are in the EU/EEA, you have the right to access, correct, or delete your personal data. You can also request a copy of your data or object to its processing. To exercise any of these rights, contact us using the details below.
