Effective date: November 12, 2026.
Arc Gnomon LLC ("we", "us") operates GolfAPI.dev, including golfapi.dev, console.golfapi.dev, the API at api.golfapi.dev and clubapi.golfapi.dev, the MCP server at mcp.golfapi.dev and our emails (the "Service"). This policy explains what personal information we collect and how we use it. The golf equipment catalog itself contains no personal information.
Summary
- We collect your email address, account and billing records, API usage, messages you send us, and technical logs.
- Stripe processes payments. We do not receive full card numbers.
- We do not sell personal information or use it for targeted advertising.
- We use only the cookies needed for sign-in.
1. What we collect
- From you: your email address and sign-in details; your plan and purchase records (payment details go to Stripe); and the name, email address, company and message you send when you contact us.
- Automatically: API usage per key and account, activity on your account, and logs that include your IP address, browser and device type, requests, and approximate location derived from your IP address.
- Page views and clicks: which pages of golfapi.dev and console.golfapi.dev are viewed and which buttons are clicked, with browser, device type, screen size, language, referring site and country (section 4).
An email address is required to create an account or receive product updates. Do not send us personal information about your own users, in API requests or otherwise.
2. How we use it
To provide and bill for the Service, answer messages, send service messages and product updates you have confirmed, secure the Service and prevent abuse, improve the Service, enforce our terms and meet legal obligations. We may use de-identified or aggregate data for any lawful purpose and will not try to re-identify it.
3. How we share it
We share personal information with service providers that process it for us, currently Cloudflare (hosting), Neon (database), Clerk (sign-in), Stripe (payments) and Resend (email), and with support and productivity tools we use. We also share it with professional advisers, when required by law or to protect rights and safety, in a merger, acquisition or sale of assets, or with your consent.
We do not sell personal information or share it for cross-context behavioral advertising.
4. Cookies and page analytics
We use only the cookies needed to keep you signed in. We do not use analytics or advertising cookies, and we will update this policy before we do. We do not respond to Do Not Track signals because we do not track you across other sites.
We count page views and clicks on golfapi.dev and console.golfapi.dev with Umami, which we host ourselves at stats.arcgnomon.com. It sets no cookies. Your IP address is used to derive your country and to group the pages of one visit, and is not stored. Recorded page addresses leave out query strings, and click counts carry no email address, account or API key.
5. Product updates
Product updates are optional. We add you only after you confirm your address, and every update has an unsubscribe link. After you unsubscribe, we keep your address on a suppression list so we do not email you again.
6. Retention and security
We keep personal information while your account is open, and afterwards only as long as needed for billing, security, disputes, legal obligations and enforcing our terms. Then we delete or de-identify it.
We use reasonable safeguards, but no system is completely secure. Keep your API keys secret. If one is compromised, revoke it in the dashboard and email security@golfapi.dev.
7. Your rights
Depending on where you live, you may have the right to access, correct, delete or receive a copy of your information, to restrict processing, and to withdraw consent at any time. Where we rely on legitimate interests, you may object to that processing at any time.
Email privacy@golfapi.dev from the address on your account. We will verify your request and will never ask for your API secret. You may use an authorized agent. If we decline a request, you may appeal by replying to our response. We will not discriminate against you for exercising your rights.
8. International users
We are based in the United States and process information there and wherever our providers operate. Where the law requires, we protect transfers with Standard Contractual Clauses or equivalent safeguards; email privacy@golfapi.dev for a copy.
For users in the EEA, UK and Switzerland, Arc Gnomon is the controller. We process your information to perform our contract with you, for our legitimate interests in operating, securing and improving the Service and answering messages, to meet legal obligations, and with your consent for product updates. You may complain to your local data protection authority.
9. Children
The Service is not directed to children. We do not knowingly collect personal information from anyone under 16, and we do not sell or share any. If you believe a child has given us information, email privacy@golfapi.dev and we will delete it.
10. Changes
We update this policy when our practices change and post the new effective date here. We will email account holders before a material change takes effect.
