Privacy

Effective October 10, 2026

This page explains what lexerian.com and Grind Tracker collect and what happens to it. The site is operated by Lexerian.

What is collected

• Account: your email address and a password. The password is stored in hashed form by the sign-in provider.
• Tracker readings: the numbers read during your sessions (level, EXP, mesos, potion counts), your usage and your credit balance.
• Screen areas: while you are tracking, the two areas of the shared window that you select are sent to the server and passed to an AI model to be read. The images are not stored by Lexerian.
• Payments: card details are entered on Stripe's payment page and never reach Lexerian. Lexerian receives confirmation of the payment, its amount and the email used.
• Server logs: the hosting provider records standard request data such as IP address and browser type.

The site has no advertising and no tracking cookies. Page views are counted with Vercel Web Analytics, which does not use cookies and does not identify individual visitors. Your sign-in session and current tracker session are kept in your browser's storage.

How it is used

To sign you in, run the tracker, keep your credit balance, process payments and refunds, prevent abuse and answer your email. Personal information is not sold or used for advertising.

Who processes it

• Supabase: accounts and stored tracker data
• Vercel: hosting and page-view counts
• OpenAI: reading the screen areas you send
• Stripe: payments

Each handles the data under its own terms and privacy policy. Information is otherwise disclosed only when the law requires it.

Keeping and deleting

Account and tracker data is kept while your account exists. To have your account and its data deleted, or to get a copy of it, email brian@lexerian.com from the address on your account. Payment records may be kept as long as tax and accounting rules require.

Children

The site is not intended for children under 13.
