Your data stays on your device
MegaCarros asks for no account and does not sync your records. Vehicles, fuel stops, charging sessions, maintenance, expenses and reminders are stored in a local database on your phone. No login, no cloud, no data selling.
The app uses Firebase Analytics for usage metrics and offers an optional support chat (Tawk.to), disabled by default. Details are in the Privacy Policy.
Questions
Frequently asked
Is MegaCarros really free?
Yes. There is no subscription, no ads and no in-app purchases. Download it, add your
vehicles and use every feature.
Does it work without internet?
Yes. Records are stored in a local database on the device, so day-to-day use does not need a
connection. Internet is only used for usage analytics (Firebase Analytics) and for the
support chat, when you enable it.
Do I need an account or login?
No. There is no sign-up and no password. That also means your data is tied to the device —
which is why backups matter.
How is consumption calculated?
Between full tanks (or 100% charges), adding up partial fills in that interval. When there is
no full tank as a baseline, the app shows an estimate starting from 4
refuels and 300 km. Values are marked as confirmed, estimated or unavailable, always with an
on-screen explanation.
Does it support electric and hybrid cars?
Yes. Just choose “Electric” or “Hybrid” as the fuel type. The app then logs charging in kWh,
price per kWh, full charge and consumption in km/kWh or kWh/100 km.
What if I change phones?
Export a backup first and restore it on the new device. You can merge with existing data or
replace everything. Keep the file somewhere safe.
Which languages are available?
English, Portuguese and Spanish, switched instantly inside the app.
