1. What are Cookies?
At Sustainable Day, we use "cookies"—small data files stored on your device—to help our ecosystem function properly. In line with our principle of Building in the Open, we want you to know exactly what we use and why.
2. How We Use Cookies
We use cookies to ensure that when you move between our subdomains (Meet, Travel, Voice, and Blog), your experience remains seamless. We categorize our cookies into three types:
Essential Cookies: These are required for the technical operation of our sites. For example, they allow you to stay logged into your session on meet.sustainable.day or remember your flight search filters on travel.sustainable.day.
Preference Cookies: These remember your choices, such as your preferred language (English, Estonian, Romanian, or Ukrainian) or your currency settings (EUR).
Analytical Cookies: We use these to understand how people interact with our mission. This helps us see which stories on sustainable.day are resonating most so we can focus our efforts where they matter.
3. Subdomain Specifics
meet.sustainable.day: Uses cookies via Trafft to manage booking sessions and prevent double-booking.
travel.sustainable.day: Uses cookies via TravelPayouts to track attribution for flight searches, which supports our mission at no extra cost to you.
voice.sustainable.day: Uses cookies via SocialJuice to ensure that if you start a video testimonial or an AI-chat, your progress is saved.
sustainable.day: Uses cookies via Ghost to manage newsletter subscriptions and member access.
4. Your Choices (Data Sovereignty)
You have full control over your cookies. Most browsers allow you to:
View what cookies are stored on your device.
Block cookies from specific domains.
Delete all cookies when you close your browser.
Please note that disabling essential cookies may prevent some parts of our booking or travel tools from functioning correctly.
5. Our Commitment
We do not use advertising cookies or "trackers" that follow you across the internet to build a profile for third-party marketing. Our focus is strictly on Connecting People and Planet, not on selling data.
