Privacy Policy

GRINDOR collects the minimum data needed to run the simulator: your email, hashed password, plan status, and simulated trade history. This information stays on our servers and is never sold.

Data Usage

Session data is used to render your positions, calculate stats, and debug performance issues. Aggregated metrics may be used to improve the product but will not identify you.

Payment Information

Paid plans are billed through Lemon Squeezy, our Merchant of Record. Lemon Squeezy handles card/PayPal processing, sales tax, fraud prevention, and compliance on our behalf. GRINDOR never stores full payment credentials. We only receive limited billing metadata (plan, charge ID, last four digits, expiration month/year) so we can provide invoices, detect failed renewals, and satisfy accounting obligations.

Billing metadata is retained as long as your account remains active and for a reasonable period afterward to comply with legal and financial record-keeping requirements. You may request removal of historic billing records after any mandatory retention window has expired by emailing contact@grindor.co.

Third Parties

We rely on Binance public APIs for market data and standard infrastructure providers (database, hosting). No advertising networks or trackers are embedded in the simulator UI. When you complete a payment, Lemon Squeezy acts as the relevant third party with its own privacy policy and compliance obligations.

Your Rights

You may request deletion of your account and related data at any time by contacting contact@grindor.co. We will confirm removal within a reasonable timeframe.
