Privacy Policy

Short version: your calculator numbers stay on your device. We collect very little, and we don't sell personal data.

What stays in your browser

• Calculator inputs and results are processed in your browser and are not sent to our servers.
• Activation status and license key are saved in your browser's local storage so you stay unlocked on that device. You can remove them by clearing your browser's site data.

Purchases

Checkout is handled by Gumroad. Gumroad collects your name, email, and payment details under its own privacy policy. We receive order details (such as your email and license key) from Gumroad so we can deliver and support your purchase.

Basic usage events

We record anonymous events to understand which parts of the page are useful:

• when a "Get Access" button is clicked, and which button (for example "hero" or "pricing");
• when a FAQ question is opened, and which question number.

These events contain no name, email, license key, or calculator inputs. If we add an analytics provider, it will be named here: [PLACEHOLDER – analytics provider, if any].

Your choices and rights

You can ask us to access or delete information we hold about you by emailing [PLACEHOLDER – contact email]. Depending on where you live (for example the EU, UK, or California), you may have additional rights. [PLACEHOLDER – confirm with a lawyer.]
