Privacy Policy

Last updated: June 26, 2026

DriveMath ("we," "us") is built privacy-first. This policy explains, in plain language, exactly what happens to your data.

The short version

Your shifts, fares, mileage, and all financial figures stay on your devices and, when iCloud sync is enabled, can sync privately through your own iCloud account. We never receive them, store them on our servers, or sell them — and we can't read your iCloud data.
We do not use any advertising or analytics tracking.
The only information that leaves your device is what's needed to sign you in (handled by Apple, Google, or Firebase Authentication — not collected by us for any other purpose).

What we store on your device

When you use DriveMath, the app saves the following on your device:

Shifts (times, gross fares, odometer/mileage, tolls, parking)
Vehicle details (MPG, gas price, maintenance and depreciation rates, insurance)
Fill-ups, maintenance records, goals, and your settings

This data is never uploaded to us. To keep it safe and available on your other devices, DriveMath stores it in your own private iCloud (Apple's CloudKit private database) when you're signed into iCloud — the same place your other app data lives. Only you can access it; we cannot, and it is not stored on our servers. When iCloud sync is enabled, it follows your device's iCloud setting, and you can turn it off in Settings → [your name] → iCloud. If you delete the app or use "Reset all data," the on-device copy is erased; data already in your iCloud can be removed from your iCloud settings.

Account sign-in

DriveMath requires an account, which you create with email, phone number, Google, or Apple, using Firebase Authentication (a service from Google LLC). To create and secure your account, the following may be processed:

Your email address and/or phone number (depending on the method you choose)
Your name, if provided by Sign in with Apple or Google
An anonymous account identifier (user ID)

This information is used solely to authenticate you. It is not used for advertising or tracking, and we do not share it with third parties beyond the authentication provider. Apple's Sign in with Apple can hide your real email via a private relay address; we fully support that.

Purchases

DriveMath Pro subscriptions are processed entirely by Apple through the App Store. We never see or store your payment details. Your subscription status is verified on-device via Apple's StoreKit.

What we do NOT do

We do not track you across apps or websites.
We do not include advertising SDKs or third-party analytics SDKs.
We do not sell or rent your personal information.
We do not access your contacts, photos, or browsing history.

Location

DriveMath does not use location services. Mileage is calculated from the odometer readings you enter yourself — the app never requests or accesses your location.

Your choices and rights

You can use most of DriveMath without sharing any driving data with us — it stays on your devices and in your own private iCloud. You can turn off iCloud sync anytime in your device's iCloud settings.
You can permanently delete your account and all data at any time from your Profile screen (or More → Data & Privacy) → Delete account. You can also erase on-device data without deleting your account via "Reset all data."
Depending on where you live (e.g., EEA, UK, California), you may have rights to access or delete personal data. Because your driving data lives only on your own devices and private iCloud, you are already in control of it.

Children

DriveMath is not directed to children under 13 and does not knowingly collect data from them.

Changes

We may update this policy; we'll revise the "Last updated" date above and, for material changes, note it in the app.
