Privacy notice

Effective 2 October 2026. Operator: Nemoto Hikaru, Japan. Contact: twinkle1774@outlook.jp.

Information we use

We use Google account identity, email and display name to identify your account; hashed sessions and API keys to authenticate requests; usage counters to enforce your plan; and Stripe customer/subscription references to manage billing. Google access and identity tokens are not saved. Card information is handled by Stripe, not stored in our database. Supplied pool inputs are processed for calculation and are not intentionally saved.

Providers and retention

The service uses Cloudflare infrastructure, Google authentication and Stripe hosted payments. These providers may process data in countries outside Japan under their own policies. Account, key, usage and subscription records are kept while needed to operate your account or resolve billing and security issues. Sessions expire after 24 hours and login-state records after 10 minutes; expired records are removed by scheduled maintenance. Webhook delivery identifiers are retained for up to 180 days for duplicate prevention. Provider operational logs and legally required financial records may have separate retention periods.

Your choices

You can revoke API keys and log out from Dashboard. Contact the operator to request access, correction or account/data deletion. Identity may need to be verified; records required by law or unresolved billing may need to be retained. No advertising cookies are required for this API Hub. Authentication uses essential secure session cookies.
