Privacy Policy

When you use newsletter sign-ups or lead-magnet PDF downloads on the Website, we may collect:

• Email address
• Optional source tag indicating which page you subscribed from (for example, a calculator or guide slug)
• Any other information you voluntarily type into a signup field

When you submit your email address through any signup form on this site - including newsletter sign-ups and lead-magnet PDF downloads such as the 2026 Freelancer Tax Checklist - your email is sent via our Vercel-hosted subscribe endpoint to Buttondown, our email service provider (buttondown.com). Buttondown processes your email under their own privacy policy. We use your email to send the requested resource, occasional editorial updates, and freelance tax tips. You can unsubscribe at any time using the link in any email.

When you visit our Website, we and our processors may automatically collect certain technical data, including:

• IP address (which may be anonymised or truncated for analytics; may also be forwarded to Buttondown for spam/firewall checks when you subscribe)
• Browser type and version
• Operating system and device type
• Pages visited and time spent on each page
• Referring URLs (the page you came from)
• Date and time of your visit
• General geographic location (country/region level, derived from IP)
• Cookie consent preferences stored in your browser (localStorage)

Values you enter into calculators and generators on the Website (for example income figures, rates, or invoice fields) are processed in your browser for the purpose of showing results on that page. We do not collect, store, or transmit those tool inputs to our servers as part of the calculation itself. If a page also offers an email signup or PDF lead magnet, only the email-related data described in Section 3.1 is sent to our processors.

We use cookies and similar tracking technologies (e.g., pixels, local storage) to operate and improve our Website. See Section 9 (Cookies Policy) for full details.
