Truecaller says Nigerians can remove their numbers after privacy ruling

Nigerians who never signed up for Truecaller now have a legal lifeline: they can unlist their numbers from a database that has been quietly scouring their phones for years. The Lagos High Court’s ruling on September 20, 2026, not only dismissed a privacy case but also clarified that the app’s “unlisting tool” is a real option for non‑users. For a country where scam calls are a daily nuisance, this is a win for privacy and a reminder that data practices can be challenged in court.

The heart of the dispute was whether a user’s agreement to upload contacts to Truecaller automatically gave the company permission to harvest the numbers of people who never opted in. The court rejected that idea outright. “The user of the app voluntarily consented to the upload of contact details on the user’s phone to the respondent is insufficient to establish implied consent,” it said. This judgment is a direct blow to the industry’s reliance on vague, blanket consent clauses. It reminds us that consent must be explicit and specific, not a catch‑all that covers everyone in a contact list. The ruling also warned that accepting the company’s theory would “completely eviscerate the rule of privacy and the definition of consent as provided by the Act.” In other words, the court is telling tech firms that the law is not a suggestion; it is a boundary.

Truecaller’s spokesperson framed the decision as a win for public safety, claiming that caller identification and spam detection protect Nigerians from scams, fraud and harassment. While it is true that many users rely on the service to avoid spam, the company’s blanket collection of non‑user data is a different story. By allowing anyone to unlist their number, Truecaller is admitting that it had been overreaching. The company’s claim that the court recognized the importance of its services is a classic “we’re doing good, so we’re justified” narrative. It is a narrative that needs to be challenged by the very fact that the court said the company must safeguard personal data and not release it to third parties without proper consent.

The ruling may ripple through the local tech ecosystem. Start‑ups that rely on data scraping for analytics or marketing will have to rethink their data acquisition strategies. If a single court can dismantle a privacy argument, the risk of legal backlash increases. I predict that within the next year, we will see a surge in Nigerian companies adopting opt‑in models for data collection, especially in sectors dealing with personal information. This shift could accelerate the adoption of GDPR‑style frameworks in Africa, pushing the continent closer to a unified data protection standard.

Truecaller’s new unlisting tool is a step in the right direction, but it is a bandage on a deeper wound. The court’s decision should be the catalyst for a broader conversation about data ownership in Nigeria. Companies must move beyond reactive compliance and embrace transparent data practices that respect users’ autonomy. If they fail to do so, we will see more lawsuits, more public backlash, and a loss of trust that will hurt the entire creator economy.

The Lagos High Court’s ruling is a landmark moment for Nigerian privacy law. It tells us that consent is not a one‑size‑fits‑all checkbox and that companies must treat personal data with the respect it deserves. For Nigerians who have never even opened the Truecaller app, the ability to unlist their numbers is a small but significant victory in a world where data is often treated as a commodity.
