Privacy Notice

Last updated: August 12, 2026

This notice explains how Purple Carbon LLC ("we," "us"), the company behind MainLine Pro, handles information you share through this website at mainlinepro.net (the "Site"). MainLine Pro is in active development; today the Site is primarily a marketing site with a waitlist signup.

Information we collect

• Waitlist details you give us. When you join the waitlist, we collect the information you submit — such as your email address and, optionally, your name, company, and team size.
• Basic usage data. Like most websites, we may collect standard analytics such as pages visited, referring site, approximate region, and device or browser type, to understand how the Site is used and improve it.

The free tools on this Site (invoice and estimate templates, calculators) run entirely in your browser. The figures you type into them are not sent to us or stored on our servers.

How we use information

• To contact you about MainLine Pro — chiefly to let you know when early access opens.
• To operate, secure, and improve the Site.
• To comply with legal obligations.

We do not sell your personal information. We will not send you a drip marketing campaign; the waitlist is a short list we contact sparingly.

Sharing

We may share information with service providers who help us run the Site and communicate with you (for example, our email and hosting providers), under agreements that limit their use of it. We may also disclose information where required by law.

Data retention

We keep waitlist information until you ask us to remove it or it is no longer needed for the purpose it was collected. You can ask us to delete your details at any time.

Your choices

• Every email we send includes a way to unsubscribe.
• You can ask us to access, correct, or delete the personal information we hold about you by emailing us.
