Generation happens in your browser
MAC addresses are generated, parsed and converted locally with the Web Crypto API. History, named pools and settings are kept in your browser's local storage and never leave your device unless you share a link.
Vendor lookups
To name a vendor, the address prefixes you generate or parse are sent to our server and matched against the public IEEE registry. We do not store these lookups.
AI features
When a Pro user runs AI setup or AI pool planning, the prompt and up to 300 addresses are sent to our AI provider to produce the result.
Account and billing data
If you create an account we store your email, name and subscription status. Payments are processed by Stripe; we never see full card numbers.
Service providers
We use Supabase (accounts), Stripe (billing), Resend (email), Sentry (error monitoring), Cloudflare (hosting) and, when enabled, Google Analytics and Microsoft Clarity.
Retention and choices
Clear your browser storage to remove local history and pools at any time. Contact us to access, export or delete account data.
