Answers before you install

Free to install and free to use. There is one thing to buy: MiExpenses Premium, a single purchase on Google Play. It opens monthly limits and expense templates, the Global statistics list without the video, and four breakdowns in the statistics menu: Year in numbers, All vehicles, Cost of ownership and Where it is cheaper, which compares what you pay at each fuel station. It is not a subscription — nothing is charged again — and where Google Play purchases do not work, the app opens those features anyway. The video is the only ad in the app, and nothing else is behind it.

Not to begin with. Continue without an account on the first screen opens a notebook that lives on this phone alone: no copy on the server, no second device, and no sharing a vehicle with anyone. Signing in is what changes that — records go to the server under that email address, come back on a new phone, and can be shared. You can sign in later, and what you recorded beforehand moves into the account by itself as long as that account is still empty.

Partly, and more than it used to. A new vehicle, category, reminder or expense can each be created with no network: they wait on the phone and go out the next time the home screen opens online. A monthly limit or a template saved offline behaves the same way, and a limit keeps counting meanwhile. What still needs the server is changing what is already on it — editing or deleting a record that has been uploaded — along with signing in and reloading everything, and there the app says so with lines like Not available in offline mode.

On a server run by the developer, reached over HTTPS. Google Drive, Dropbox and other cloud storage are not part of the chain. What is stored there, and who else can see it, is set out in the privacy policy.

Install the app, sign in with the same account, and vehicles, expenses, categories, reminders and sharing are downloaded again. Monthly limits (Budget in the menu) and expense templates come back too, as long as they reached the server — that is part of MiExpenses Premium. Whatever stayed on the old phone alone stays there, so export a CSV first if you want a copy.

There is no automatic backup: nothing is copied anywhere on a schedule, and there is no cloud copy to fall back on. What there is, is a file you make yourself. Export one vehicle to CSV, and Data → Import in the side menu reads that file back into the app; running an import twice is safe, because anything already there is skipped. The file has to be one MiExpenses exported — it will not read another app's. Restore deleted vehicle in the vehicle list is a separate thing, it undeletes a vehicle you removed. And what brings your records to a new phone is still signing in to the same account.

Yes. Share the vehicle with another registered account by email at one of three levels: View, Edit or Move ownership. From the moment the invitation is sent the server counts that account as having access, and the vehicle shows up in their app once they accept.

From two full fill-ups of the same fuel: the distance between their odometer readings against everything that went into the tank after the earlier full one. Until a vehicle has two such fill-ups the figure is a dash, not a zero. Electric charges always count as full, partial fills are used only if you switch that on in Settings, and a vehicle running on two fuels gets a separate figure for each.

Android 8.0 and newer, installed from Google Play.

No. MiExpenses is an Android app, and there is no iPhone version today.

By email. The app has no delete-account screen, so write from the address you sign in with to contacts@mve.suxlv2.space and say what you want removed: one vehicle, the records, or the account. What is held and how a request is handled is described in the privacy policy.

The email address you sign in with, your vehicles and expense records, and a push token so reminders can arrive. On start-up it also asks a third-party service for your country by IP address, and the Google ad SDK loads on every launch; there is no crash-reporting SDK, and there is no location, camera or microphone permission in the app — though GET_ACCOUNTS, which Play lists under Contacts, is declared and never used. The full list is in the privacy policy.
