Alcaraz has a coach, a trainer, a physio, a nutritionist, a mental performance coach, and a data analyst. Your child has you and a notes app. CourtSide gives every competitive junior tennis family the same data infrastructure the pros have.
Our Philosophy
CourtSide exists to help families keep their eyes forward and their footing steady. In a sport filled with emotion, noise, and constant judgment, we believe parents serve their children best by choosing clarity over reaction and patience over pressure.
"Let your eyes look directly forward, and your gaze be straight before you.
Ponder the path of your feet; then all your ways will be sure."
Proverbs 4:25-26
Everything the pros track, built for the families behind every competitive junior.
Chart matches in real time from your phone courtside. Four detail levels — from tapping the winner of each point to full shot-by-shot analysis with placement and rally length. Start simple, go deeper when you're ready.
Capture what the scoreboard doesn't — effort, compete level, enjoyment, reflections. After 50 matches, the patterns in how your child responds to wins and losses tell you more than any stat.
Month-by-month view of activity, trends, and growth. Rolling average comparisons instead of single-month snapshots. Subtle load awareness when activity is notably above baseline.
Track every hour on court — matches, practice, lessons, free play. Watch cumulative hours build toward development milestones from 250 to 10,000 hours. See your child's pace projection and know exactly where they are in the journey.
Auto-groups matches by tournament. Daily reflections after multi-match days. Full tournament summary with results, progression, and the emotional arc of the weekend.
Build head-to-head records over time. Track play styles, scouting notes, and match history against every opponent. In junior tennis, you play the same kids — that history matters.
CourtSide grows with you. Start by tracking scores, then add journals, training connections, and opponent scouting at your own pace.
Not every parent wants to track serve placement. Not every match needs full analysis. CourtSide's four charting tiers let you choose your depth — and switch mid-match if you want.
After every match, CourtSide prompts a simple reflection — effort, compete level, enjoyment, and an optional free-text journal. It takes 60 seconds and creates the most valuable data in the entire app.
Individual matches are noise. Development happens over months and years. CourtSide's Progress Timeline, trend analysis, and rolling averages help you see what actually matters.
Every piece of data starts private. Parents decide what to share with their coach — and can change their mind anytime.
Parents can opt in to share any of these categories with their coach. The default is private — you choose what to open up.
Some families share everything with their coach. Some keep reflections private. CourtSide gives you the control — the default just makes sure nothing is shared until you're ready.
CourtSide gives coaches a dedicated mobile app for on-court work — video capture, lesson logging, and player lookup — plus a web portal for roster management and analytics. See match data, trends, and opponent history from matches you couldn't attend. Families control what else to share. You get better-prepared parents and better conversations.
Film a stroke during a lesson, slow it to 0.25x, annotate body position and racket path, record voice-over coaching notes, and send it to the family with one tap. Compare today's footage side-by-side with video from three months ago.
Tap to start a lesson — auto-logs duration to the player's court hours. Tag focus areas, write session notes, and set homework. Everything pushes to the family's Coach Log automatically. No double-entry.
Pull up any player before a lesson: recent match results, current training block, gear setup, court hours this week, and any shared journals. Walk on court knowing exactly where they are.
See exactly how many hours each player has spent on court — broken down by matches, practice, lessons, and free play. Know who's putting in the work between lessons and who's dropping off, without having to ask.
Journals, effort ratings, and reflections start private. Families who trust their coach can opt in to share any of it. You don't ask for access — they offer it when they're ready. That trust makes the data better for everyone.
When your families subscribe, you earn a referral — $5/mo per Pro family, $10/mo per Elite family, capped at 24 months per family. With 20 active families, that's $100-200/mo in passive income just for being a great coach.
Academy Partnerships
If you run a program and your families are already using CourtSide, we offer bulk licensing so you can provide it as part of your academy experience. Better-engaged parents, structured tournament feedback, and training block alignment — without adding to your coaching workload.

Auto-capture weather at match time or quick-select conditions manually. Over 50+ matches, see how your player performs in heat vs. cold, wind vs. calm, hard court vs. clay. Data that tells you where to focus training.
Log what they ate and drank before and during matches. Not calorie counting — just observational tracking. Over time, spot patterns: "Matches with a meal 2+ hours before had 23% higher effort ratings in the final set."

CourtSide stores photos and videos of your children. That responsibility shapes every technical decision we make.
Every login requires SMS verification — not optional, not "recommended." Biometric unlock for quick re-entry after verification. New device detection triggers additional verification.
AES-256 encryption at rest for all stored media. TLS 1.2+ in transit. Private storage with short-lived access links — no persistent URLs to your family's photos or videos.
Designed for families with minors from day one. Only parents create accounts. No direct data collection from children. No behavioral advertising. No selling or sharing of family data. Ever.
Rally AI is scoped to tennis, tournament logistics, and your family's data. It won't offer medical advice, mental health counseling, or stray into non-tennis topics. Purpose-built boundaries, not generic filters.
Every CourtSide account requires multi-factor authentication. Not optional, not toggleable, not something families can skip "for convenience."
Parents create accounts with email + phone number. Every login requires SMS verification. Biometric unlock after session is established. 30-day session expiry forces re-authentication. Tokens are encrypted on-device, never in plain text.
Coaches get a mobile app for on-court work — video capture, lesson logging, player lookup — plus a web portal for roster management and analytics. Email magic links plus SMS verification. No passwords to manage, no passwords to leak. Full audit logging on every login and data access. Parents can revoke access instantly.
Match data, journal entries, videos, photos — everything is encrypted at rest and in transit. No public buckets, no unprotected endpoints, no shortcuts.
Row-Level Security: CourtSide uses database-enforced data isolation. Your family's data is invisible to other families — not by application logic, but by database policy. Even if the application had a bug, cross-family data leaks are architecturally impossible.
COPPA — the Children's Online Privacy Protection Act — requires special protections for data about children under 13. CourtSide tracks data about junior tennis players, so COPPA compliance isn't optional. It's foundational.
Rally is a tennis assistant — not a general-purpose chatbot. It's purpose-built for match analysis, tournament logistics, and player development. It's explicitly blocked from topics it has no business discussing.
Two layers of enforcement: Rally's topic boundaries are enforced by a constrained system prompt and a topic classifier that screens every query before it reaches the AI. Off-topic, medical, and mental health queries are caught and redirected to the right professional — a doctor, a therapist, a nutritionist. Respectful, clear, immediate.
The coach dashboard supports the player-coach relationship — on the parent's terms.

Sell your data to third parties. Run behavioral advertising. Share data with analytics companies. Use your child's information for marketing. Allow unencrypted media storage. These aren't settings you can toggle — they're architectural decisions baked into how CourtSide is built.
Not at all. Start with Score + Notes — just tap who won each point. That's it. You can layer in more detailed charting as you get comfortable. The journal and development features don't require any tennis knowledge.
Not unless you choose to share it. Journals, reflections, effort/compete/fun ratings, and tournament daily reflections are all private by default. As a parent, you can opt in to share any category with your coach — and turn it off anytime. You're in control.
One subscription covers your entire family. Each player has their own profile, match history, opponents, training blocks, and journals — all completely separate. Switch between players with a tap.
Use Quick Match to log a match after the fact — enter the score, opponent, and a quick journal note. Or have your player use the Player Match Log to self-report. Not every match needs live charting.
Security is foundational, not optional — especially because CourtSide stores photos and videos of your children. Every login requires SMS verification (MFA). All media is encrypted at rest and in transit. Videos and photos are stored in private buckets with short-lived access links — there are no persistent URLs to your family's content. We're COPPA-compliant from day one, we never sell or share your data, and we never serve ads. Reflections are private by default — only shared with your coach if you choose to opt in.
CourtSide is built for tennis right now. The development tracking, journal system, and privacy model apply to any individual competitive sport — and we plan to expand after we've proven the model in tennis.
