Privacy policy

Last updated November 13, 2026. This policy explains what Epic Stuff, Things & Co. collects when you buy and use Aerion.

When you buy

Checkout is run by Lemon Squeezy, which collects your name, email, billing address and payment details under its own privacy policy. We receive your name, email, plan, subscription status and the last four digits of your card. We never see your full card number.

When you activate

To activate and renew a license, the app sends our license server your purchase email, your license key and a machine code made from your computer's hardware. We use these only to check your license, limit it to the computers you pay for, and stop key sharing.

Your projects

Projects are saved on your computer. They are not sent to us unless you use a business workspace with team seats, where shared project files are stored so your team can open them.

Online lookups

Some features look things up online when you use them: elevation and county from a project address, heat pump listings, and current material prices. Those requests send only what the lookup needs, such as the address or coordinates. If you use the optional AI assistant, the text and drawings you send it go to an AI service to produce the answer.

This website

This site has no tracking or advertising cookies. Fonts load from Google Fonts.

Keeping and deleting data

We keep license records while your subscription is active and for a reasonable time afterward for tax and fraud purposes. Ask us to delete your data by replying to your receipt email.

Changes

We will post any changes to this policy here.
