About Us

Meet the folks behind the plug

🚗 We are a small crew of EV drivers, commuters and road-trip fans who got tired of range numbers that only hold true on a sunny test track. ChargeyWargey was born from our own garage notebooks.

🌍 Our mission is simple: make electric driving feel calm and predictable by turning battery management into a precise, stress-free routine for every owner.

🔋 The app gives you a real-world range scaler, a charging cost and efficiency log, a battery health journal and monthly analytics, all in one cozy workspace that runs fully offline.

⚡ Because knowing your range, costs and battery health means fewer surprises, longer pack life and more confidence at every junction. Charge smart. Drive far. Stay chargey.

None. ChargeyWargey does not collect any personal data, usage data, location, vehicle identifiers or device information.

2. How We Use Information

Since we hold no information, we do not use, analyze, profile or sell anything. Your range inputs, charging sessions and SoH entries are used only to show results to you.
