Two official languages, French and Arabic, shape the Chadian web: news sites and government pages often publish in both, with standard Arabic in writing and Chadian Arabic in speech, radio and social video. Prices are in Central African CFA francs (XAF), the currency shared with Cameroon and the other CEMAC countries. Most imported goods reach N'Djamena through Cameroon, along the Douala corridor and across the Chari river from the border town of Kousséri, so shipping costs on that route feed into shelf prices in the capital.
N'Djamena's online sellers work without a national marketplace: they advertise on Facebook and WhatsApp and take payment in cash or through Airtel Money and Moov Money, the wallets of the two main mobile operators, Airtel and Moov Africa. That makes publishers and operators the main monitoring targets. Alwihda Info and Tchadinfos are widely read online news sites, Le Progrès is a long-running daily, and the state media office ONAMA runs Télé Tchad with news in French and Arabic. Airtel and Moov Africa publish bundle prices and wallet fees that change with promotions.
Language decides what Chadians see in search. On Google, the dominant engine, French queries about Chad often return Cameroonian or French pages, while Arabic queries compete with sites from across the Arabic-speaking world. Personal data falls under Law No. 007/PR/2015 of 10 February 2015 on the protection of personal data, with implementing Decree No. 075/PR/2019 and supervision by ANSICE.
Outside N'Djamena, Chad's markets follow different languages and economies. Moundou, the second-largest city and capital of Logone Occidental, is the main city of the Ngambay-speaking south, with an industrial base around Brasseries du Logone, maker of the Gala beer brand, and cotton ginning and processing by CotonTchad. Abéché, capital of the Ouaddaï region in the east, is largely Arabic-speaking and lies on the road towards Adré on the Sudanese border, where aid agencies run large operations for refugees from Sudan, so humanitarian procurement and notices shape local demand. Online listings and news from both cities are sparse, so regional checks need town names, not just the country.
