Privacy Policy for Driver's Log

Last updated: July 2, 2026

This policy explains what data Driver's Log ("the App") collects, how it's used, and where it's stored. Your trip, financial, and profile records stay on your device — there is no account system and we never sell your data. The App uses Firebase (Google) for crash reporting and basic usage analytics, Google AdMob to show ads, and an optional AI feature that sends an aggregated summary of your activity to a cloud service, all described below.

Data the App Collects

Data	Why it's collected	Where it's stored
GPS location	To track mileage during a shift and to detect individual trips automatically	On your device only
Receipt photos	To read amounts off a receipt via on-device text recognition	Processed on your device; the photo itself is not retained after scanning
Voice audio	To let you log an entry by speaking instead of typing	Processed on your device via on-device speech recognition; audio is not retained or transmitted
Trip, revenue, expense, and shift records you enter	To power mileage history, financial tracking, and tax estimates	On your device only
Aggregated activity summary (AI Insights feature)	To generate personalized financial tips via the AI Insights feature	Sent to a Firebase Cloud Function and Google's Gemini AI when you request insights; raw records are never sent — only totals and category breakdowns
Advertising ID	To serve ads via Google AdMob	Managed by Google AdMob; see below
Crash and error reports	To diagnose and fix bugs	Sent to Firebase Crashlytics (Google); see below
App usage data (screens viewed, feature usage, app opens)	To understand which features are used so we can improve the App	Sent to Firebase Analytics (Google); see below

The App does not require an account and does not collect your name, email, or any other personal identifier as part of analytics or crash reporting. Your location, receipts, voice audio, and full financial records are never included in analytics events, crash reports, or AI requests.

How Data Is Used

Location is used exclusively to calculate mileage and detect trip start/end points while a shift is active. It is never transmitted to any server operated by us or any third party.
Receipt photos and voice audio are processed entirely on your device using Google's on-device ML Kit and speech recognition. Nothing is uploaded.
Trip, revenue, and expense records you enter are used to calculate totals, generate the tax estimates shown in the app, and produce exports you initiate yourself.
AI Insights — when you tap "Get Insights", the app computes an aggregated summary (total revenue, expense category totals, total miles, and mileage statistics for the past 30 days) and sends only that summary to a Firebase Cloud Function, which forwards it to Google's Gemini AI to generate tips. Your individual trip or transaction records are never sent.

Data Storage and Backup

All personal data is stored locally in the app's private storage on your device. If you have Android's automatic backup enabled (the default on most devices), this data is backed up to your own Google Drive account by Android itself — we do not operate or have access to that backup. Uninstalling the app or disabling backups will remove this data permanently unless you've exported it yourself (the app includes a CSV export feature for this purpose).

Permissions Requested

Location (including background) — for shift/mileage tracking.
Camera and Photos — for receipt scanning and vehicle photo.
Microphone — for voice-entry logging.
Notifications — to show a persistent reminder while a shift is active and for maintenance reminders.
Bluetooth — to connect to OBD-II diagnostic adapters (optional feature).
Advertising ID — used by Google AdMob to serve ads. You can opt out via your device's advertising settings.

Each permission is requested only when the corresponding feature is first used, and the app remains usable (with that feature disabled) if a permission is declined.

Third-Party Services

The App uses Google's on-device ML Kit (text recognition) and Android's Speech-to-Text APIs, both of which run locally on your device. No data processed by these APIs is sent to Google or any other party by this app.

The App also uses the following third-party services:

Google AdMob — displays ads within the App, including rewarded ads that unlock features. AdMob may collect your Advertising ID, device identifiers, and usage data to serve relevant ads. You can opt out of interest-based ads in your device settings under Privacy > Ads. AdMob is governed by Google's Privacy Policy.
Google Play Billing — processes any in-app purchases or subscriptions. Payment information is handled entirely by Google Play and is not accessible to us. Governed by Google Payments Privacy Policy.
Firebase Cloud Functions & Google Gemini AI — when you use the AI Insights feature, an aggregated summary of your activity is sent to a Firebase Cloud Function operated by us, which passes it to Google's Gemini AI to generate tips. No raw trip records, exact amounts, or personal identifiers are included. Governed by Google's Privacy Policy.
Firebase Crashlytics — automatically collects crash reports and error diagnostics (e.g. device model, OS version, app version, and the stack trace of what failed) so we can identify and fix bugs. It does not receive your trips, financial records, location, receipts, or voice audio.
Firebase Analytics — automatically collects basic usage data (e.g. which screens you open, how often the app is opened) to help us understand which features are actually used. It does not receive your trips, financial records, location, receipts, or voice audio.

All Firebase and Google services are governed by Google's Privacy Policy. Data sent to these services may be used by Google in accordance with that policy and is retained according to each service's standard data-retention settings.

Children's Privacy

This App is not directed at children under the age of 13. We do not knowingly collect personal information from children.

Changes to This Policy

If this policy changes, the "Last updated" date above will be revised accordingly. Continued use of the App after a change constitutes acceptance of the updated policy.
