Privacy Policy — OdoGrid

1

Overview

OdoGrid is designed to protect your privacy by default. The app operates entirely offline and does not transmit your vehicle data to any external server owned or operated by us.

All vehicle details, fuel logs, maintenance records, trip logs, and expenses are stored locally on your device inside an AES-256 hardware-backed encrypted Isar database. No account is required. No cloud registration. Your data belongs to you.

Third-Party Services

OdoGrid integrates with the following third-party services. Each operates under its own privacy policy:

Google AdMob Android only

Displays ads after consent is granted (GDPR compliant). Three ad formats are used: banner ads on list pages, rewarded ads gating premium exports and AI Assistant analysis, and frequency-capped interstitial ads shown at most once every three saves across fuel, maintenance, and expense entries. Users can purchase a one-time Remove Ads entitlement.

Google Drive Optional

If you enable backup, your encrypted database is stored in your own Google Drive appDataFolder — invisible to all other apps. OdoGrid does not have access to the rest of your Drive.

Google Privacy Policy →

Dropbox Optional

If enabled, encrypted backup ZIPs are stored in your Dropbox app folder /Apps/OdoGrid. OdoGrid does not access your other Dropbox files. Auto-backup silently skips if Dropbox has not yet been connected in the current session — the app never opens a browser or OAuth prompt in the background without your explicit action.

Firebase Crashlytics Diagnostics

Collects crash diagnostics to improve stability and reliability. It does not collect your vehicle log content.

Google Privacy Policy →

Firebase Analytics Product analytics

Helps measure app usage and feature quality trends. Vehicle records remain stored locally in the encrypted on-device database.

Google Privacy Policy →

Google ML Kit On-device only

OCR text recognition for receipt scanning runs entirely on-device using the Google ML Kit Text Recognition API. No images or scan results are ever uploaded.

Advertising & Consent

We display ads via Google AdMob on Android only. On first launch, you are presented with a GDPR consent dialog. You may decline personalised ads — the app remains fully functional with non-personalised ads shown instead.

Banner Ads

Small static banners shown at the bottom of list pages (fuel, maintenance, expenses). Non-intrusive and always visible.

Rewarded Ads

Short video ads shown when you choose premium exports (Tax Report, Export History, PDF, Excel) or run AI Assistant analysis. If the ad fails to load, the requested action proceeds immediately as fallback — you are never blocked.

Interstitial Ads

Full-screen ads shown at most once every three saves combined across fuel, maintenance, and expense entries. They appear after the form closes so you are never interrupted mid-task.

You can also purchase a one-time Remove Ads entitlement via Google Play Billing to disable all ads permanently.

5

Data Export & Deletion

You can export all your data at any time from Privacy & Data → Export My Data in JSON, PDF, or Excel format. Each export is gated behind a short rewarded ad; if the ad fails to load the export proceeds immediately. Exports include real stored values (including VIN and plate number).

To permanently delete all data, go to Privacy & Data → Wipe Data. This deletes the encrypted database and all secure hardware-backed keys from your device. This action is irreversible.

6

Cloud Backup & Auto Sync

Once you complete your first successful backup or restore for a provider, OdoGrid enables automatic backup by default — no additional configuration required. The app silently backs up your encrypted database each time it is brought to the foreground, provided the configured interval (Daily, Weekly, or Monthly) has elapsed since the last successful run. You can adjust the backup frequency at any time from Backup & Sync in the app — it is not limited to the Settings page.

If you connect Google Drive, your encrypted Isar database is transferred directly to your personal Google Drive appDataFolder — invisible to all other apps. OdoGrid does not have access to your Google credentials or the contents of the uploaded file. Backups are compressed (ZIP), timestamped, and auto-deduplicated so only the latest backup is retained. A Google Drive restore fully replaces your local database.

If you connect Dropbox, encrypted ZIP backups are stored in your Dropbox app folder (/Apps/OdoGrid). OdoGrid does not access your other Dropbox files. Dropbox restores merge missing records into your existing local data. If Dropbox has not been connected in the current session, scheduled auto-backups skip silently — the app never opens a browser or OAuth prompt in the background without your explicit action.
