Privacy
We count visits without cookies, we keep your email only if you buy a sheet or write to us, and we never sell anything about you.
Visits
We run our own visit counter instead of an advertising tracker. It records the page, the referring site, rough scroll depth and time on page, outbound link clicks, and which layouts you looked at, so we know which rooms to draw next. It uses a random session id kept in your browser's session storage, cleared when you close the tab. No cookies, no cross-site profile.
Buying a sheet
Payment is handled by Stripe; we never see your card. We keep your email, the layout you bought and the order record so we can send the sheet, and send it again if you lose it. Orders are kept for five years for accounting.
Messages
If you write to us, we keep your name, email and message so we can reply, for up to 24 months.
Links to stores
Some pages link to products on Amazon. As an Amazon Associate we earn from qualifying purchases. Amazon may set its own cookies on its site; its privacy policy applies there.
Your data
Ask us to show or delete what we hold about you at hello@madetwenty.com and we will do it within 30 days. Drain and Vent is operated by GTMFM.NO.
