We're in preview. These terms take effect when we start taking real orders.

This covers what Caliper Air LLC, an Indiana limited liability company, collects when you use caliperair.com, and what we do with it. The short version: we collect what we need to make and ship your filters, and we don't sell it.

What we collect

• Your email address and, if you give it, your mobile number.
• Your delivery address.
• Your orders, subscriptions and saved filter sizes.
• If you turn on Face ID or fingerprint sign-in: a passkey's public key. Your fingerprint or face never leaves your device.
• If you use a photo to find your size: we read the photo to find the size and don't keep it.

Card details go straight to Stripe, our payment processor. We never see or store your full card number.

Text messages

If you turn on text reminders in your account, we text the mobile number you give us about your deliveries: usually one text before each box ships and one on filter-change day, and replies when you text us. Message and data rates may apply. Reply STOP to stop all texts, or HELP for help. We don't share or sell your mobile number or your text opt-in to anyone for their marketing. Sign-in codes by text are sent only when you ask for one.

Checkout has a "Keep me updated with news and personalized offers" box that starts ticked. If you leave it ticked and don't finish checking out, we may email you up to two reminders about your cart. Untick it and we won't. Every reminder has a link to stop them.

How we use it

To make and ship your orders, run your subscriptions, send reminders and receipts, answer you when you write to us, and keep the site secure.

Who we share it with

Only the companies that help us do those things: Stripe for payments, Cloudflare to run our website and send email, Twilio to send sign-in codes by text if you choose that, and the carrier delivering your package (UPS, USPS or FedEx). We don't sell your information or share it for advertising.

We share your name and shipping address with the manufacturer that makes your order, only so they can ship it. They must delete it within 60 days of delivery and can't use it for anything else.

Cookies

We use two cookies. One keeps you signed in. The other is a random ID, kept for up to 180 days, that remembers which creator, friend or link brought you here (so we can thank and pay them) and which version of a page we're testing you saw, along with steps like adding to your cart. It isn't used for advertising. Your cart is saved in your own browser. We don't use advertising cookies or third-party trackers.

Your choices

You can update your details anytime in your account, and delete your account there too, which erases your sizes, subscriptions and order history. Some records, like payment records, we keep as long as tax law requires. Questions or requests: hello@caliperair.com.

Children

Caliper is for adults. We don't knowingly collect information from anyone under 16.
