Cookie Policy
Last updated: 24 September 2026
I. What cookies are
Cookies are small text files a website stores in your browser. They help the site work, remember your choices and — only if you agree — measure traffic or how well our advertising works.
II. Categories
Necessary — needed for the site and the secure checkout to work, and to remember your cookie choice. These do not require consent.
Analytics — help us understand how visitors use the site. Only with your consent; never loaded before you give it.
Marketing — measure advertising performance. Only with your consent; never loaded before you give it.
III. Cookies we use
- cookie_consent — stores your cookie choice for up to 12 months. Necessary.
- Polar — our Merchant of Record's checkout sets necessary cookies to process your payment, prevent fraud and keep the checkout session secure.
- Cloudflare — our hosting provider may set necessary security cookies (such as __cf_bm) to protect the site from bots and attacks.
At present the site uses no analytics or marketing tools. If we add one, it will load only after your consent and we will list its cookies here.
IV. Changing or withdrawing consent
You can change your choice at any time:
- via (also in the site footer),
- by clearing cookies in your browser,
- by writing to hello@upsidedownmuseum.com.
Declining optional cookies does not affect your ability to browse or buy.
V. Do Not Track
There is no uniform standard for Do Not Track signals, so the site does not respond to them. You can control optional cookies through the cookie settings at any time.
