## What is Founta Lab?

Founta Lab is the recording app of the Founta research project: together we are building a dataset of tennis serves used to train serve-analysis models.

Record your own serves right on the court. Your clips upload automatically and robustly — even on a poor connection — and enter the research corpus once you confirm them. You always see what happens with your footage: upload status, detected serves, and your contribution on the team leaderboard.

ACCESS BY APPROVAL ONLY
Founta Lab is a research project, not an open social network. After signing in with Apple you need an access code, or a manual approval by our team. That is how we make sure nobody — especially no minors — ends up in the dataset without deliberate, verified consent. No code yet? Write to us: contact@tkmedia.lu

FEATURES
• Guided serve recording with automatic on-device serve counting
• Automatic upload that resumes after connection drops
• Your recordings at a glance: status, detected serves, points
• Leaderboard and team goals for approved members
• Player profiles for children — created and managed exclusively by parents or guardians, with explicit consent
• Delete your account any time, directly in the app

PRIVACY
Your footage is used exclusively for research on serve-analysis models — never for advertising and never sold to third parties. Details: https://founta-labeling-privacy.vercel.app/datenschutz

Operated by TK MEDIA S.à r.l.-S, Luxembourg.
