The EU-US Privacy Shield ("Privacy Shield") is a framework for US-based organizations.
monday.com Ltd is based in Israel and as such does not need Privacy Shield as Israel is a country that offers adequate level of data protection in accordance with an adequacy decision made by the EU.
You can see the list of countries HERE.
Having said that, our customers data is hosted by Amazon Inc. which is certified with Privacy shield. In addition, monday.com has a US entity (monday.com Inc.) that provides sales and customer success services for monday.com customers. This entity is Privacy Shield certified as well.
