Data Collection and Sharing

The flashcard apps do not collect, store, or share personal data. They do not
require user accounts, do not include ads, and do not use analytics.

CityKing is a web-based city discovery app connected to cityking.com. CityKing
does not require an account and does not include ads. When you use CityKing,
our servers may automatically receive standard technical request data, such as
IP address, browser or device information, requested URLs, timestamps, and error
logs. This data is used to operate, secure, debug, and improve the service. We
do not sell this data.

In-App Purchases

Some flashcard apps offer one-time premium upgrades. Purchases are processed by
Google Play Billing or Apple. We do not receive or store your full payment card
details.

Text-to-Speech

The flashcard apps use your device's built-in text-to-speech engine for
pronunciation. No voice recordings are captured or transmitted by us.

Local Storage

The apps may store limited app data locally on your device, such as preferences,
premium unlock status, favourites, progress, or cached website data. You can
remove this local data by clearing app storage or uninstalling the app.

Data Retention and Deletion

For apps that do not send data to our servers, we do not retain personal data
remotely. For CityKing, standard server logs are retained only as needed for
operation, security, debugging, and abuse prevention.

You can delete local app data at any time by:
1. Clearing app storage in your device settings, or
2. Uninstalling the app.

Children

These apps are intended for users aged 18 and over.

Security

App and website network communication is performed over secure connections
(HTTPS) where available.
