Privacy Policy

Calculator inputs

The calculators run in your browser. Amounts, countries, currencies, tax rates, APR values, and other inputs are used to update the result on the page; they are not PayPal login information.

Analytics and cookies

The site may use analytics, consent tools, and advertising services to understand page usage and support the project. These services can process page views, device/browser details, approximate location, referral pages, cookie identifiers, and consent choices.

Where cookie consent is required, analytics and advertising cookies should follow the consent settings shown on the site. You can also control cookies through your browser settings.

Information you should not send

Do not send PayPal passwords, full card numbers, government ID numbers, private account screenshots, or other sensitive account data when reporting a calculator issue. A country, currency, amount, calculator name and source link are usually enough.

Contact messages

If you contact SellerMaths by email, the message can include your email address and the information you choose to send. That information is used to respond to corrections, source updates, or feedback.

No PayPal account access

The site does not ask for PayPal login credentials and does not connect to a PayPal account.

Data control

If you contact SellerMaths, you can ask for your message to be deleted. Browser-based calculator inputs can be cleared by resetting the form, refreshing the page, or clearing your browser data.
