# 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](https://policies.google.com/privacy) and
[AdMob's data disclosure](https://support.google.com/admob/answer/6128543) — 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.
