As Typhoon Bavi barrels toward Taiwan with winds near 200 kph, authorities are urging residents to stock up on supplies and prepare for what could be the strongest storm since 2024. But amid the panic, a new convenience has emerged: hyper-local weather apps that promise real-time tracking, personalized alerts, and even automated supply lists. You can now get a push notification telling you exactly when to buy bottled water and how many sandbags to stack. But here's the doubt: what happens to all that data? Your app knows your location, your home's vulnerability (based on elevation and proximity to rivers), your shopping habits (via synced grocery lists), and even your response time to alerts. Some apps now offer 'storm readiness scores' that gamify preparation. But is that score just for you—or is it being sold to insurance companies? If the claim were true, the consequence would be absurd: your flood insurance premium could spike because you bought water at 3 p.m. instead of 2 p.m., or because you ignored a 'high-risk zone' warning. Data brokers could bundle your typhoon response profile with your credit score, and landlords might use it to evict tenants who 'failed' to prepare. Imagine a future where your smart home's storm shutters report your compliance to an insurer, and your coffee maker's blackout timer is used to prove you were home during the storm. In the end, the question is: who is the storm really tracking? As Typhoon Bavi approaches, the real tempest may be the one in your data profile. Smart for whom?
