Privacy Policy — Show Me The Fuel Refund

Effective date: August 17, 2026

This policy explains what "Show Me The Fuel Refund" (the "app") does and does not do with your data. If anything here is unclear, contact ohbrer+ShowMeTheFuelRefund@gmail.com.

Overview

The app helps you collect and organize Missouri fuel purchase receipts so you can claim Missouri's Motor Fuel Tax Refund. It has no server or backend of its own — every vehicle, fuel receipt, and photo you log is stored locally on your device, and optionally backed up to a cloud storage account you choose and control. We (the developer) never receive, see, or have access to a copy of your data.

Data Stored Locally

The app stores the following on your device only, unless you connect a cloud storage account (see below):

  • Vehicle information you enter (VIN, nickname)
  • Fuel purchase records (date, gallons, price, total cost)
  • Receipt photos you capture or select

This data is never transmitted to us. Uninstalling the app, or never connecting a cloud backup, means this data exists only on that device.

Optional Cloud Backup

If you connect a cloud storage account in Settings, a copy of the data above is also stored there — in storage you control:

  • Google Drive — via Google Sign-In and the Drive API
  • Dropbox — via the Dropbox API
  • Microsoft OneDrive — via the Microsoft Graph API
  • WebDAV — your own self-hosted server (Nextcloud, ownCloud, or similar)

For OAuth-based providers (Google Drive, Dropbox, OneDrive), the app requests only the permissions needed to create, read, and write files in a folder it manages there. We do not read, log, or have access to anything stored in these accounts — the connection is directly between your device and the provider you chose. For WebDAV, your server credentials are stored using your device's OS-level encrypted storage (Android Keystore) and are used only to connect directly to the server you specify.

Advertising (Google AdMob)

Unless you've purchased "Remove Ads for a Year," the app shows a single interstitial ad, at most once per app session, via Google AdMob. AdMob may collect data such as an advertising identifier and coarse, IP-based location to serve and measure ads. This collection is Google's, governed by Google's own privacy policy and AdMob's data disclosure — it is not something this app adds on top of, and we have no access to it.

In-App Purchases

"Remove Ads for a Year" is processed entirely through Google Play Billing. We do not receive or store payment information — that's handled by Google Play directly.

What We Don't Do

  • No analytics SDKs
  • No crash-reporting SDKs
  • No tracking of your usage or behavior
  • No server of ours that receives, stores, or processes your data
  • No selling or sharing of data with anyone, for any reason

Data Deletion

You can delete your data at any time from Settings > Data > Advanced (purge all data, or a specific date range), and disconnect any cloud storage account from Settings > Data. Deleting the app removes everything stored locally; anything already backed up to your own cloud storage account remains there under your control until you delete it yourself.

Children's Privacy

This app is not directed at children under 13 and does not knowingly collect data from them.

Changes to This Policy

If this policy changes, the effective date above will be updated. Continued use of the app after a change constitutes acceptance of the updated policy.
