Privacy Policy

Last updated October 13, 2026

Advanced Thermal Concepts LLC (“ATC,” “we,” “us”) operates this air filter store. This policy describes what we collect, why, and the choices you have. The short version: we collect what we need to ship filters to you, and we do not sell your information.

What we collect

  • Order information: your name, email, phone, and shipping address when you place an order, start a subscription, request a custom size, or submit the contractor or contact forms.
  • Cart contents: stored locally in your own browser so your cart survives a page reload. This stays on your device.
  • Basic usage data: standard web logs and privacy-focused analytics from Vercel (page views, approximate region). We do not build advertising profiles.

How we use it

  • To fulfill and ship your orders and manage your subscription.
  • To respond when you contact us.
  • To send order-related email. Other email only if you opt in or join the Filter Club (which includes our monthly tips email), and every one has an unsubscribe link.
  • To send one filter tips email a month to Filter Club members and to shoppers who tick the tips box at checkout. Every one has an unsubscribe link, and unsubscribing does not change your filter deliveries.
  • To understand which pages and sizes people use so we can improve the store.

What we share

Only what is required to operate: our filter supplier and the shipping carrier receive your name and shipping address to send and deliver your order; our payment processor receives payment details to charge your card (we never see or store full card numbers); our email provider sends transactional messages. We do not sell or rent personal information to anyone.

Retention and your choices

We keep order records as required for accounting and warranty purposes. You can ask us to correct or delete your personal information, unsubscribe from any marketing, or request a copy of what we hold. Email mstoll@advancedthermalconcepts.com and we will handle it within 30 days.

Children

This store is not directed at children under 13 and we do not knowingly collect their information.

Changes

If this policy changes materially, we will update the date above and note the change here. October 13, 2026: orders are now shipped to you by our filter supplier, who receives your name and shipping address to do it. Questions: mstoll@advancedthermalconcepts.com or (270) 534-5492.
