Privacy policy.
The plain-English version: we collect what we need to reply to you and to understand how the site is used, and nothing is ever sold. Effective July 11, 2026.
What we collect
If you contact us or book a constraint check, we receive what you submit: your name, email, business details, and whatever you write about your situation. Bookings are handled by Cal.com, so your booking details are also processed by them under their own privacy policy.
Like most sites, we collect aggregate usage analytics (pages visited, referring site, general region, device type). This data is anonymous in aggregate and is used only to understand what is working.
How we use it
To respond to you, to prepare for and run your constraint check, to follow up on work you have asked about, and to improve the site. We do not sell or rent your information to anyone, and we do not run third-party advertising or ad tracking.
Who touches the data
The service providers that run this site: Vercel (hosting and analytics), Cal.com (scheduling), and email and database providers used to receive and store inquiries. Each processes data only to provide their service to us.
Your choices
Want to see, correct, or delete what we have about you? Email hello@616software.com and it will be handled by a human, promptly.
Changes
If this policy changes in a way that matters, this page will be updated and the effective date above will move.
