What we collect

• Free calculator: the calculation runs on your device only. We do not send the numbers you enter to our servers or store them.
• Orders: when you order the model we store your email address, order number, date and status so we can deliver the file and follow up the payment. You enter your card details with the payment provider directly; we never see or store them. We send the delivery email through an email delivery provider (Resend) and do not use your email for anything else.
• Aggregate statistics: we count daily visits and calculator starts and completions as totals only, grouped by the channel you came from (for example X or WhatsApp) if your link carried one, with no identifier for you. We also use cookie-free visit statistics.

Why we collect it

To deliver what you bought, and to understand what business owners need and improve the product.

What we do not do

• We do not sell your data or share it with anyone for marketing.
• We do not send you messages you have not agreed to.

Where the data is stored

With the hosting provider that runs the website.

Your rights
