Live station listSort by price and compare ETA, distance and pump prices at a glance.
Private historyRefueling history stays on the device and helps build personal price insights.
Cross-deviceContinue naturally from iPhone to CarPlay when it is time to drive.
Designed around the journey
From search to best price to insights.
View the best prices first, compare nearby options, inspect a station in more detail, view insights, start navigation, and keep the actual refill price for future insights.
Compare first, decide with confidence.
The station list highlights the essentials immediately: price, distance, ETA and the best-priced stop nearby. Open any station to see more context, including the current price, how it compares with your last refuel, how it compares with nearby stations, and quick access to your preferred maps app.
Station listNearby fuel stations are easy to scan and already sorted the way cost-conscious drivers expect.
Station detailPrice context appears right where the decision happens, instead of being buried in a separate flow.
iPhone and CarPlayThe same core information carries across both screens so the experience stays familiar when the journey moves into the car.
Your refuels become useful beyond the moment.
Tank Radar is not only about finding a station right now. The app also keeps a local record of what you actually paid, letting Price Insights surface trends, price history and the historically cheapest day to refuel based on your own usage.
Price insightsSee recent trends, historical price changes and patterns drawn from your own refueling history.
Refuel historyEvery stop stays available as a clean timeline that is easy to review later.
Editable final priceIf the actual pump price differs, you can correct the history entry and keep your records accurate.
Built to feel at home in the car.
CarPlay extends the same station and price context into a layout that stays simple while driving.
At-a-glance list viewPrice, ETA, distance and best-price context remain readable on the car display.
Route handoffDrivers can move from discovery to navigation without leaving the flow.
History correctionThe full narrative still makes room for updating the final paid price directly from CarPlay.

This Privacy Policy explains how I, Damian Perera ("I", "me", or "my"), an individual developer based in Bavaria, Germany, collect, use, and protect your information when you use the Tank Radar iOS application ("the App"). I am committed to protecting your personal data and complying with the General Data Protection Regulation (GDPR).
Information I Collect and How I Use It
Tank Radar collects two categories of data: your device's geographical location (to provide core functionality) and anonymised usage analytics (to improve the App). Both are processed with care and in full respect of your privacy.
Location Data
I request your precise or approximate location via iOS system permissions.
This location data is used exclusively in real-time to query third-party APIs and display nearby gas stations.
Your location data is not linked to your identity, device ID, or Apple ID.
I process this data based on your explicit consent provided through the iOS location permission prompt, which you can revoke at any time in your device settings.
Analytics Data (Google Analytics for Firebase)
I use Google Analytics for Firebase to collect anonymised usage data to understand how the App is used and to improve its features and performance.
The following table summarises all data processed by the App:

No Personally Identifiable Information (PII)
Google's terms expressly prohibit sending any Personally Identifiable Information (PII) to Firebase. No names, email addresses, Apple IDs, or precise GPS coordinates are ever transmitted to Google Analytics.
Data Storage and Security
I do not operate backend servers that store your personal information.
Location data is processed temporarily in the device's memory to fulfil the API request and is never written to disk, transmitted to me, or logged anywhere.
Analytics data, is transmitted to and stored by Google on Firebase infrastructure in accordance with Google's security and data retention policies.
I do not transmit, log, or store your location history, searches, or any other personal data on my own servers.
Because I do not operate data stores myself, the risk of data breaches affecting your personal information through my systems is virtually eliminated.
External APIs and Third-Party Services
To provide the App's core functionality and to analyse usage, I interact with the following third-party services:
Data Transmission: Fuel API providers receive anonymous coordinate data only. They do not receive any identifying information about you or your device from me.
Google as Data Processor: Google operates as a data processor under a Data Processing Agreement (DPA) included in Google's Terms of Service.
Limitation of Liability: I do not own or control these external services and am not liable for how third-party providers collect, use, or protect data transmitted to them. Their respective privacy policies govern any data they process.
Analytics and Tracking
Tank Radar uses Google Analytics for Firebase to collect anonymised usage data. This helps me understand which features are used, how the App performs across different devices, and where to focus future improvements.
What is collected: App Instance ID, Identifier for Vendor (IDFV), device model and iOS version, App version, language, session duration, screen views, and in-app events (e.g. station viewed, map interaction).
What is NOT collected: Precise GPS coordinates, your name, location, email, Apple ID, payment information, or any content you personally interact with. Google's terms prohibit the transmission of any Personally Identifiable Information to Firebase.
Changes to This Privacy Policy
I may update this Privacy Policy from time to time to reflect changes in my practices, the services I use, or legal obligations. I will notify you of any significant changes by updating the "Effective Date" at the top of this document and, where the change materially affects your rights or requires renewed consent, through an in-app notification and a fresh consent prompt.
