Opera is a web browser for desktop and mobile (Windows, macOS, Linux, Android and iOS) with a built-in ad blocker, a free built-in VPN and integrated messengers. Variants such as Opera GX and Opera Air exist, along with AI features inside the browser. The desktop edition is based on Chromium and distributed as freeware rather than open source.
Opera was born in Oslo, and the data controller for the browser and its services is Opera Norway AS, based in Oslo. The parent company, Opera Limited, is incorporated in the Cayman Islands, is listed on NASDAQ and, according to Wikipedia, is majority-owned by the Chinese company Kunlun Tech. For a European organisation this is a relevant ownership signal: control sits outside the EU. The privacy statement also describes sharing data with other companies in the Opera group and with partners, relying on mechanisms such as standard contractual clauses for transfers outside the EEA. According to Opera, AI chat prompts are processed by OpenAI or Google.
