This privacy policy describes how the app “EV Calculator” (hereinafter “the app”) handles your data. Protecting your privacy is important to us. The app was designed to collect and process as little data as possible.

The app is designed to process as little data as possible. There is:
Your app data is stored primarily on the device. Optionally and transparently, Apple iCloud is used to sync between your own devices, and anonymous contributions are sent to a public vehicle catalog (see Sections 4 and 6).
You can create vehicle profiles with technical data (name, manufacturer, model, battery capacity, consumption values, charging power, charge levels, electricity price). This data is:
If you disable iCloud or sign out, the data remains exclusively on the local device.
Your app settings (language, units, currency, consumption mode, display mode, charger filters, iCloud sync toggle) are stored locally in your device’s UserDefaults.
If you enter a custom API key for Open Charge Map, it is stored locally on your device. It is only used for direct requests to the respective service.
On first launch, the app generates a random UUID once and stores it locally. It is used solely to associate anonymous catalog contributions (see 6.4) with a device so that updates can be recognized. It has no relation to your Apple ID, name, location, or device hardware (no UDID, no IDFA, no IMEI).
The app uses your location only while actively in use (“While Using”). Your location is needed for:
Your location is not permanently stored and is not shared with third parties for advertising or analytics purposes. The location is only kept in memory while the app is active.
The app communicates with external services only in the following cases:
When you actively search for charging stations, the following data is transmitted to the selected provider:
This transmission occurs only upon your active request (e.g., when you open the map or plan a route).
When planning routes, start and destination coordinates are processed through Apple’s MapKit service. Apple’s privacy policy applies: https://www.apple.com/legal/privacy/
The app downloads a publicly visible JSON file with a curated list of electric vehicles from GitHub (raw.githubusercontent.com, repository beyerste/EMC-Vehicle-DB). No personal data is transmitted in this process — it is a simple HTTPS download comparable to fetching a web page. GitHub may log technical data such as IP addresses according to its privacy policy: https://docs.github.com/site-policy/privacy-policies/github-privacy-statement
To help grow the vehicle catalog, the app by default submits anonymous vehicle data to Apple’s CloudKit Public Database (container iCloud.de.beyerste.EVManualCalculation).
What is transmitted: Manufacturer, model, display name, battery capacity, consumption values (WLTP/city/rural/highway), maximum and average charging power, catalog reference ID (if selected from catalog), device hash (random UUID), submission timestamp, app version, and selected language.
What is NOT transmitted: Apple ID, UDID, IDFA, name, email, location, electricity price, personal charge levels (minimum/target/arrival), route planning data, search queries, or any other usage data.
Use: The submitted data is used exclusively to expand the public vehicle catalog with quality-checked entries. It is not shared, not used for advertising, and not analyzed.
Control: You can disable this feature at any time in the app settings under “iCloud → Anonymous Contributions to Vehicle Catalog”. After disabling, no further data will be transmitted. You can request deletion of previously submitted records (see Section 10).
The app does not establish any other network connections. There are no analytics servers, no ad networks, and no other third-party services.
The CarPlay feature displays charging stations and vehicle data on the CarPlay screen. It uses the same data and services as the main app (see sections 5 and 6). No additional data is collected.
The app does not share personal data with third parties, except in the cases described in section 6 (charging station search and route calculation), where technically necessary data (coordinates) is transmitted to the respective services.
All locally stored data is subject to the security mechanisms of your iOS device (app sandbox, device encryption). Communication with external services is conducted exclusively via encrypted HTTPS connections.
You can at any time:
Deletion of anonymous catalog contributions: If you would like already-submitted anonymous contributions to be removed from the CloudKit Public Database, contact us with your anonymous device hash (visible in Settings → Diagnostics, if enabled) or the manufacturer/model of the affected vehicles. We can then manually remove the records.
iCloud data: Data in your iCloud Private Database is tied to your own Apple ID. We as the app provider have no access to it. You can delete this app’s iCloud data separately via iOS Settings.
The app is not directed at children under 13 and does not knowingly collect data from children.
This privacy policy may be updated with app updates. Significant changes will be communicated in the app’s release notes.
