Privacy

Your finances are personal. The calculators run in your browser, and we collect as little as we can.

Without an account

The numbers you enter stay in your browser on this device (local storage). They aren’t sent to our servers, to advertisers or to analytics.

With an account

• Your email address, so you can sign in with a one-time code. Accounts are run by Supabase.
• Your plan, so Premium works on any device.
• Calculations you choose to save (the inputs and the one-line result), so your history follows you. Nothing is saved unless you press “Save to history”.

When you open a Premium schedule, the inputs for that schedule are sent to our server to calculate it and are not stored. The same email can sign in to our other ChowChow Labs sites, but each site keeps its own data.

Payments

Premium is sold by Paddle.com, our reseller and Merchant of Record. Paddle collects your payment details and billing address; we never see your card.

Advertising

Free visitors see one Google AdSense banner. Google may use cookies to show and measure ads; see how Google uses data from sites that use its services. Your mortgage inputs, income and debts are never shared with Google or any advertiser. Premium members load no ad scripts.

What we never collect

• Your address, identity documents or credit information
• Loan applications (we don’t take any)
• Precise location

Keeping and deleting your data

We keep your account and saved calculations until you remove them on the History page or delete your account on the Account page. Purchase records may be kept longer where tax law requires it.
