Umit Kaya ("we", "us") is committed to protecting your privacy. This Privacy Policy explains how information is collected, used, and safeguarded when you use the DBC Cards mobile application for iOS, distributed on the App Store as "Business Card Maker - Digital" (the "App").
The short version: the business cards you create and collect never leave your device. There is no account, no sign-in, and no server of ours that stores your data. The only information that leaves your device is what our advertising and purchase providers need in order to show ads and process a purchase, described in detail below.
1. Information We Collect
1.1 Information You Provide
The App lets you create digital business cards and store cards you have received in a Card Holder. The information you enter — such as name, job title, company, phone number, email address, postal address, website and social links — and any photograph or logo you add:
- Is stored only in a local database on your device
- Is never uploaded to, or stored on, any server operated by us
- Is never sold, rented, or shared with third parties
- Leaves your device only when you personally choose to share a card, using the iOS share sheet, to a recipient and channel that you select
1.2 Camera and Photo Library
With your permission, the App can use your camera or photo library so you can add a picture to a card — for example a headshot for a personal card, or a company logo for a work card. Images you take or select are copied into the App on your device only, and are used only on the cards you create. The App does not scan, upload, or transmit your photo library. You can withdraw camera or photo access at any time in iOS Settings.
1.3 Information Collected Automatically by Third-Party Services
The App itself does not operate analytics or user profiling. However, the third-party services listed in Section 3 may automatically receive limited technical information, such as device model and operating system version, general device and app configuration, an advertising identifier (only where you have permitted tracking), IP address, and interactions with advertisements or purchases.
2. Advertising and App Tracking Transparency
The App is free and supported by advertising delivered through Google AdMob.
On first use, iOS presents an App Tracking Transparency prompt asking whether the App may track you across other companies' apps and websites:
- If you allow tracking, your device's advertising identifier (IDFA) may be shared with Google AdMob so that advertisements can be made more relevant and their effectiveness measured
- If you decline, no advertising identifier is shared and you will still see advertisements, but they will be non-personalized
- Your choice can be changed at any time in iOS Settings → Privacy & Security → Tracking
The App also supports Apple's SKAdNetwork, a privacy-preserving framework that lets advertisers measure campaign performance without identifying you individually.
The business cards and contact details you store in the App are never shared with advertisers.
Google's handling of this data is governed by its own policies: Google Privacy Policy and How Google uses information from partner apps.
3. Third-Party Services
The App uses the following third-party services, each of which has its own privacy policy:
- Google AdMob — serves advertisements within the App, as described in Section 2
- RevenueCat — manages the optional one-time "Pro" purchase. RevenueCat receives purchase and receipt information and an anonymous, randomly generated app user identifier, together with basic device and platform information. It does not receive your name, email address, or any card content. See the RevenueCat Privacy Policy
- Apple — processes the purchase itself and may provide us with aggregate, anonymised App Store analytics. See the Apple Privacy Policy
We do not use Facebook, Firebase, or any other analytics or attribution SDK in this App.
4. Purchases
The App offers a single optional one-time purchase ("Pro") that removes advertisements. All features of the App are available whether or not you buy it.
Payment is handled entirely by Apple through your App Store account. We never receive or store your payment card details, billing address, or Apple ID credentials. We receive only confirmation, via RevenueCat, that a valid purchase exists so that advertisements can be switched off and your purchase restored on your other devices.
5. How Information Is Used
- To provide the App's core functionality — creating, storing, and sharing your cards
- To display advertisements, personalized only where you have permitted tracking
- To validate and restore the optional Pro purchase
- To diagnose crashes and technical problems, and improve stability and performance
- To respond to support requests you send us directly
6. Data Storage and Retention
Card data and images are stored in a local database on your device, protected by the security of iOS itself. Because we operate no server and hold no copy of this data, we cannot access, recover, or restore it.
Your data is retained on your device for as long as the App is installed. Deleting the App permanently removes all cards, contacts, and images it stored. Please export or back up anything you wish to keep before uninstalling. If you use iCloud or encrypted iTunes/Finder device backups, App data may be included in those backups under Apple's terms and your own settings.
7. Data Sharing
We do not sell, rent, or trade your personal information. Information is shared only with the service providers named in Section 3, strictly for the purposes described, or where we are legally required to do so.
8. Your Choices and Rights
- Tracking — allow or deny at any time in iOS Settings → Privacy & Security → Tracking
- Camera and photos — grant or revoke at any time in iOS Settings
- Deletion — delete any individual card inside the App, or delete the App to remove all of its data from your device
- Access and portability — all of your data is already on your device and visible to you within the App; you may share or export any card at any time
Depending on where you live, you may have additional rights under laws such as the GDPR or the CCPA. Because we hold no personal data on any server, most such requests are satisfied directly on your device using the controls above. For anything further, contact us using the details in Section 11.
9. Children's Privacy
The App is a business utility intended for general audiences and is not directed at children. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will take appropriate steps.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with a revised "Last Updated" date. Material changes will additionally be reflected in the App Store listing. Continued use of the App after an update constitutes acceptance of the revised policy.
