Privacy Policy

1. Who we are

Ten-Fifty5 ("Ten-Fifty5", "we", "us") provides AI-powered tennis match analysis. You upload match video and we return performance statistics, biomechanical (pose-based) technique analysis, and an AI coaching assistant grounded in your own data.

• Data controller: Ten-Fifty5
• Contact: info@ten-fifty5.com
• Data protection contact: info@ten-fifty5.com

This policy explains what we collect, why, the legal bases we rely on, who we share it with, how long we keep it, and the rights you have.

2. Who this applies to

Players, parents/guardians managing a junior's account, and coaches who use Ten-Fifty5. Because we analyse video of people playing tennis, a match you upload may contain personal data about other people (e.g. your opponent). See Section 9 on footage of third parties.

3. The data we collect

Account & profile (personal data)

Name, email, phone (optional), country, role (player / parent / coach), and login credentials (authentication is handled by our provider, Clerk).

Junior / minor profile data

Where a parent or guardian sets up a junior, we may hold the child's date of birth, skill level, club or school, and coaching notes. Accounts for minors are managed by a consenting adult — see Section 8.

Match video

The video you upload. The original upload is deleted after processing; a trimmed review clip is retained as part of your match history.

Biometric data (special category)

To produce technique analysis we extract skeletal pose / keypoint data (the position of body joints across frames). We treat this as biometric data and, where applicable, as a special category of personal data under Article 9 GDPR. We only process it on the basis described in Section 6.

Match analytics (derived data)

Statistics derived from your video — serve placement, rally metrics, KPIs, technique scores.

Usage data

Events such as logins, uploads, report views, and AI-coach queries, used to operate and improve the service.

Payment data

Payments are processed by PayPal. We do not store your card details.

4. Where your data comes from

Almost all of it comes directly from you (your account details and the video you upload) and from your use of the service (usage events, derived analytics). For juniors, the managing adult provides the child's details.

5. How we use your data

• Provide the core service: process your video into statistics, technique analysis, and AI coaching.
• Maintain your match history and progression over time.
• Operate, secure, troubleshoot and improve the platform.
• Communicate with you about your account and analyses (service messages).
• Send marketing communications only where you have opted in (Section 7).
• Comply with legal, tax and accounting obligations.

6. Legal bases for processing (GDPR / UK GDPR)

• Contract — to deliver the analysis you sign up for (account, video processing, analytics, AI coach).
• Consent — for biometric/pose processing (explicit, opt-in consent collected before your first technique analysis), for marketing email (Section 7), and for processing a minor's data via parental consent (Section 8). You can withdraw consent at any time (Section 10).
• Legitimate interests — to secure, maintain and improve the service, where not overridden by your rights.
• Legal obligation — to retain certain financial records (Section 11).

7. Marketing communications

We send marketing email (tips, product updates, offers) only to people who have explicitly opted in. For EU/UK signups we use double opt-in (a confirmation click) before adding you to any marketing list. Every marketing email has an unsubscribe link, and you can opt out at any time without affecting the service. Service/transactional messages (e.g. "your analysis is ready") are not marketing and are sent as part of delivering the product. Our marketing email is delivered via Klaviyo (Section 12).

8. Children's data and parental consent

Ten-Fifty5 is designed to be used by adults, including parents/guardians and coaches who manage junior players. Accounts involving a minor must be created and managed by a consenting adult.

• We process a minor's data (including biometric/pose data from their match video) only with verifiable parental/guardian consent. We treat players under 16 as minors requiring parental consent.
• The consenting adult can review, export or delete the minor's data at any time.
• We do not knowingly let minors create their own accounts or direct marketing at minors.
• If you believe a minor's data has been provided without proper consent, contact info@ten-fifty5.com and we will act promptly.

9. Footage of other people

A match video may show other individuals (e.g. your opponent or doubles partners). By uploading, you confirm you have a proper basis to share that footage with us for analysis. We process incidental third-party data only to deliver your analysis, apply the same retention and security to it, and will respond to any rights request from an identifiable individual in the footage.

10. Your rights

Subject to your jurisdiction, you may have the right to: access your data; correct it; erase it ("right to be forgotten"); restrict or object to processing; data portability; and to withdraw consent at any time (including for biometric processing and marketing). Where we rely on consent for biometric data, withdrawing it means we stop technique/pose processing going forward.

To exercise any right, contact info@ten-fifty5.com. We handle requests as data-subject requests and respond within the timeframe required by law (generally one month under GDPR/UK GDPR). You also have the right to complain to your data protection authority.

11. How long we keep your data (retention)

We keep personal data only as long as needed for the purposes above. Our retention periods are set out below.

On account closure or consent withdrawal we delete or anonymise data per these rules, except where we must retain limited (anonymised) financial records to meet legal obligations.

12. Who we share data with (sub-processors)

We do not sell your data. We share it with vetted providers strictly to run the service:

We contractually require these providers to protect your data and process it only on our instructions. For the current, authoritative list — including each provider's data categories, region and transfer safeguards — see our Sub-processors page.

13. International transfers

We operate in both the United States (us-east-1) and the European Union (eu-north-1). Your data — including video and biometric data — may be processed in either region. Where data is transferred internationally, we rely on appropriate safeguards (e.g. Standard Contractual Clauses) as required by law.

14. Security

We use appropriate technical and organisational measures to protect your data, including access controls and encryption in transit. No system is perfectly secure, but biometric data and minors' data receive heightened care, and we never route them into marketing or CRM tools.

15. Cookies & analytics

We use necessary cookies to run the site. To understand how many people visit we use privacy-friendly, cookieless first-party analytics: it sets no cookies, stores no personal data, does not track you across other sites, and is never sold or shared for advertising. It records only aggregate, non-identifying signals (page counts, a coarse new-vs-returning measure via a first-party identifier, device type, approximate country from the network edge, and time on page). Because it cannot identify you, it runs without a consent prompt.

Non-essential cookies — marketing, and any third-party product analytics (e.g. Amplitude) for signed-in product usage — only run with your prior consent, captured via our cookie banner. You can change your choices anytime via the Cookie settings link in the footer.

16. Changes to this policy

We may update this policy. Material changes will be notified and the version/effective date above will change. Continued use after an update means the updated policy applies.
