Privacy Policy

1. Introduction

A2A Protocol ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you visit our website a2aprotocol.ai and when you use features such as our product directory, paid product and sponsored article submissions, and user accounts.

2. Information We Collect

We may collect the following types of information:

• Contact and inquiries: personal information such as name and email when you contact us or subscribe to updates.
• Accounts: submissions and purchases require an account. You can sign in with Google or with a one-time email code. We store your email address, display name, and profile image (if your sign-in provider shares one), plus a session record used to keep you signed in. Email sign-in codes are stored only in hashed form and expire within minutes; the code email is delivered by our email provider. When you sign in with Google, Google processes your authentication under its own privacy policy.
• Paid submissions: product listings and sponsored articles are paid features tied to your account. When you pay, we store an order record linked to your account (amount, status, and payment identifiers from the checkout provider). When you submit, we collect the details you provide — for products, the URL, name, description, and images; for sponsored articles, the title, article content, cover image, and tags — so we can review the submission, publish it if approved, and communicate with you about it.
• Security verification: we use Cloudflare Turnstile before sending email sign-in codes. Turnstile may process technical data (which can include your IP address as part of bot detection) according to Cloudflare's policies. We send the Turnstile response token and may pass a client IP to Cloudflare for server-side verification.
• Payments: payments for submissions are completed on Stripe (or another checkout link we configure). We do not receive or store your full payment card details on our servers; payment data is handled by that provider under its own terms and privacy policy. We may receive limited payment-related information needed to confirm a transaction (for example, whether a payment occurred, the email you provide at checkout, or identifiers the platform provides).
• Published directory data: if we approve and publish a listing, we may display information such as the product name, description, URLs, logos or screenshots, and categories, as shown on the public Products pages. Sponsored articles we approve are published on our Insights pages with a clear Sponsored label, including the article content, title, cover image, and links you provide.
• Usage data and analytics.
• Cookies and similar tracking technologies.

3. How We Use Your Information

We use the collected information for:

• Providing and maintaining our website and directory
• Reviewing submissions, preventing abuse, and operating our admin tools
• Communicating with you about your submission or account-related matters
• Improving user experience
• Analyzing website usage

4. Third-Party Services

We rely on service providers to host our site, store data, verify traffic, send emails, and process payments. These providers process information on our behalf and under their own policies. Examples include Cloudflare (hosting, database, email delivery, and Turnstile), Google (sign-in with Google), analytics tools we enable, and Stripe for checkout. We encourage you to review their privacy notices.

5. Retention

We retain submission and directory records as needed to operate the service, comply with law, resolve disputes, and enforce our agreements. One-time sign-in codes expire within minutes of delivery, and sessions remain valid only until you sign out or they expire. Retention periods may vary by data type; contact us if you have questions about deletion where applicable.

6. Data Security

We implement appropriate security measures to protect your personal information. However, no method of transmission over the Internet is 100% secure.
