Privacy Policy

1. Information We Collect

  • Account information: email, password (stored as scrypt hash; the platform cannot view your plaintext password), optional display name, phone number, Google OAuth identifier.
  • Usage records: teams you follow, matches you subscribe to, your Q&A interactions with the AI, archive, subscription and renewal records.
  • Technical information: access IP (used for risk control and aggregate statistics, not permanently linked to personal identity), device / browser UA, cookies.
  • Payment information: payment amount, order number, payment channel; payment credentials are handled directly by PayPal / Alipay / WeChat Pay. The Service does NOT store credit card numbers, payment passwords, or card CVV codes.

2. How We Use This Information

  • To provide subscription, AI commentary, Q&A and paid billing services
  • To protect account security (anomaly login detection, credential-stuffing detection)
  • To analyze overall usage patterns for product improvement (aggregated statistics, not individual targeting)
  • To comply with applicable laws and regulations

3. Cookies & Session

The Service uses the following cookies:

  • sa_session: session cookie, valid for 30 days, HttpOnly, used to maintain login state.
  • sa_locale: language preference cookie, valid for 1 year, readable by frontend JavaScript, used to remember your Chinese / English language selection.
  • sa_theme: theme preference (stored in localStorage rather than as a cookie), used to remember your dark / light mode selection.

The Service does NOT use any cross-site tracking cookies and does NOT participate in any advertising network. We use Umami (a privacy-respecting open-source analytics tool) for anonymous page-view statistics; we do not collect personally identifiable information for analytics purposes.

4. Data Storage & Security

  • Data is stored on servers located in mainland China, using industry-standard security measures (TLS in transit, database access control, password hashing).
  • Passwords are stored using scrypt hashing; platform staff cannot read your original passwords.
  • The Service does not proactively sell or exchange your personal data with third parties. If data must be processed by a partner, this will be disclosed before sharing.

5. Third-Party Services

  • api-football: used to fetch publicly available match data; no user personal information is uploaded.
  • PayPal / Alipay / WeChat Pay: when processing payment orders, only the necessary amount and order number are transmitted; your email or password is not transmitted.
  • Google OAuth: on sign-in we receive your Google email and basic profile (only name / picture); we do not access your contacts or email content.
  • LLM Services (OpenAI / Gemini-compatible API gateways): only factual evidence related to the specific match is transmitted when generating commentary and Q&A; your account information is not transmitted.
  • Cloudflare: provides CDN and Tunnel for network requests; see Cloudflare's Privacy Policy for details.
