Overview
This policy explains how the Vexilla iOS app and this support website handle information. Vexilla minimizes data collection and does not require a Vexilla account or custom login to learn flags.
Information in the app
Vexilla stores learning progress, achievements, activity, preferences, free daily allowances, purchase access status, and pending Game Center score submissions locally on your device. This information supports app features and is not sent to a Vexilla-operated account or cloud service.
Flag artwork and network requests
Vexilla includes its country information and map borders in the app, but it does not bundle a complete library of flag image files. When full flag artwork is needed, the app requests a PNG image from FlagCDN. As with an ordinary web request, FlagCDN may receive information such as your IP address, request headers, and device-related request metadata under its own practices.
iOS and the network response may cache downloaded artwork, so a previously loaded image can sometimes remain available without a new request. Vexilla does not guarantee that cached artwork will be available offline. If a full flag image cannot be loaded, the app shows the country's Unicode flag emoji instead; the bundled map borders remain available independently of flag artwork.
Flag artwork is provided through FlagCDN, a service created by Flagpedia using source artwork from Wikimedia Commons. Flagpedia describes the service as free for mobile apps and says it appreciates a backlink; this acknowledgment is provided in that spirit.
Optional Game Center
Vexilla connects to Apple Game Center only after you choose to enable it. Apple and GameKit may process your Game Center player identity, display name, authentication status, and eligible scores under Apple's policies. Vexilla does not use Game Center as an app login or send your Game Center identity to a Vexilla-operated server. Leaderboard availability depends on the Game Center services configured for the app.
Support and correction messages
When you choose to contact support, share feedback, or report incorrect data, Vexilla prepares an email for you to review, edit, and explicitly send. Depending on the report type, it can include your chosen description, topic, selected country or territory, suggested correction, source URL, Vexilla version and build, and iOS version. Vexilla does not attach hidden diagnostic logs, a persistent device identifier, or account credentials.
Your email provider or Apple Mail handles delivery. If you send the message, the Vexilla support inbox receives your sender address and the content you chose to include. That information is used only to investigate the message, reply when appropriate, improve Vexilla, and maintain an evidence trail for factual corrections.
App Store purchases
Vexilla offers a one-time lifetime Pro purchase through Apple's StoreKit. Apple processes the purchase and payment. Vexilla receives and uses verified transaction and entitlement information needed to unlock Pro features and restore access; it does not receive your full payment-card or bank details.
Retention and deletion
Local app information remains on your device until the app removes it through its normal behavior or you delete the app or its data. Support messages are retained only as long as reasonably needed to investigate the issue, maintain a correction record, respond to you, and protect the integrity of the support channel. You may request deletion of a support message by emailing the address below from the same account that sent it.
Children
Vexilla is intended for a general audience and is not in Apple's Kids Category. The app does not ask a child to create a Vexilla account or provide personal information to use its core learning features. A parent or guardian may contact support with questions or deletion requests.
Changes to this policy
This policy may change when Vexilla's features or data practices change. The effective date at the top of this page will be updated when material revisions are published.
