Truecaller is a smartphone app that identifies incoming calls from unknown numbers and blocks spam and unwanted calls. It is installed on the user's own phone rather than run on an organisation's infrastructure, so an organisation that allows it mainly decides which employee devices may use it. The company is based in Stockholm, Sweden, and its class B shares have been listed on Nasdaq Stockholm since October 2021.
Ownership is widely held: the co-founders hold high-vote class A shares that give them a majority of the voting power, while investors such as Sequoia Capital India and Atomico are shareholders. The company's own 2022 investor material states that a Swedish entity processes the data of EU users in data centres in Sweden under the GDPR, while a separate entity based in India is the controller for users outside the EU and data of Indian users is stored in India. Organisations should review the current privacy policy before allowing the app on managed devices.
