The generator remembers your rows, URL patterns and paths, and the checker remembers your last few URLs, using localStorage on your device. This never leaves your browser.

Sent to our server

• Hreflang checker: the URL you enter and the alternates found on it, so our server can fetch them. We don't store them; hosting logs may briefly record requests.
• AI planner: your site description is sent to an AI model through Vercel AI Gateway to draft tags. It's not stored by us or used for anything else.
• Validator and generator: run entirely in your browser. Nothing you paste is uploaded.

Analytics

We use Ahrefs Web Analytics, a cookieless tool that counts page views without identifying you.
