How we handle your data
Effective date: March 2026 · Last updated: September 2026
This site is a free tennis equipment information service. We do not ask for or store any personal information — there are no accounts, no questionnaires, no cookies and no advertising trackers, and we sell nothing to anyone.
Tennis Pro Equipment Database is a website that provides information about professional tennis player equipment. We are the data controller for any personal data processed through this site.
Our hosting provider (Netlify) may log standard server-side information such as IP addresses and request timestamps as part of its infrastructure operation. This is governed by their privacy policy and is not accessible to us in identifiable form. We hold no database of visitors and store nothing about you ourselves.
The racket comparison tool can generate a written analysis of two frames using Anthropic's Claude AI. Only the specifications of the two rackets you selected are sent — no personal data, no identifiers and nothing about you or your game. Neither the request nor the result is stored on our side.
We maintain a database of professional tennis players and their publicly known equipment (racquets, strings). This data relates to public figures acting in their professional capacity and is sourced from publicly available sporting information.
| Purpose | Legal Basis (GDPR Art. 6) |
|---|---|
| Operating, securing and serving the website | Legitimate interest (Art. 6(1)(f)) — our host must process request data to deliver pages and defend against abuse |
The following third parties are involved in operating this site:
| Provider | Role | Privacy Policy |
|---|---|---|
| Netlify | Website hosting and serverless function execution | netlify.com/privacy |
| Anthropic (Claude AI) | Generates the written analysis in the racket comparison tool from racket specifications only | anthropic.com/privacy |
| Google Fonts | Web font delivery (your IP address is transmitted to Google when fonts load) | policies.google.com/privacy |
We operate no user database, so there is nothing for us to retain. Server logs held by Netlify are subject to their own retention schedule. Racket specifications sent to Anthropic for the comparison tool are subject to Anthropic's data retention policies; Anthropic's API does not use inputs to train models by default — see their privacy policy for details.
Under GDPR you have the right to:
Because we do not store personal data, in most cases there will be nothing for us to return or delete — but contact us any time and we will confirm that in writing.
This site does not use cookies, tracking pixels, or advertising networks. No user sessions are tracked across visits. Your light/dark theme choice is kept in your own browser's local storage and is never transmitted to us.
Anthropic and Netlify are US-based companies. Data transferred to them is covered by their respective data transfer mechanisms (e.g., EU Standard Contractual Clauses).
