Cookie Policy

Effective Date: June 5, 2026

This Cookie Policy explains how Quelper LLC (“we”, “us”, “our”) uses cookies and similar technologies on www.quelper.com. It should be read together with our Privacy Policy and Terms of Use.

1. What are cookies?

Cookies are small text files a website stores on your device. They let the site remember your actions and preferences (such as your sign-in session and language) and, where you allow it, measure how the site is used. Some technologies we describe here (e.g. browser local storage) are not technically cookies but serve a similar purpose; we treat them the same way.

2. How we ask for your consent

Strictly necessary cookies are always active because the site cannot function without them — they do not require consent. For everything else (currently: analytics) we ask first:

  • EU/EEA, UK and Switzerland: non-essential cookies are off by default and are only set after you opt in via the consent banner.
  • Other regions: analytics may be enabled by default, and you can opt out at any time from the same banner or via “Cookie settings” in the footer.

Your choice is stored in a first-party cookie (cookie_consent) for 12 months. You can change it whenever you like through the “Cookie settings” link in the footer, or by clearing the cookie in your browser.

4. Third parties

Cookies set by third parties are governed by their own policies: Supabase, Stripe, and Google.

5. Managing cookies in your browser

Besides our banner, you can block or delete cookies through your browser settings. Note that disabling strictly necessary cookies will prevent you from signing in or making payments.

6. Changes to this policy

We may update this Cookie Policy from time to time. Material changes will be reflected by the “Effective Date” above, and where required we will ask for your consent again. Questions? Email s.alekhin@quelper.com.

We value your privacy

We use strictly necessary cookies to run Quelper and, with your consent, analytics cookies to see how it's used. Read our Cookie Policy and Privacy Policy.
