1. Information used on your device
WDGZ PRO stores your language, display currency, and watchlist in local device storage so your choices are available when you reopen the app. Calculator inputs and results are processed in app memory. The app does not create a permanently saved calculation history. Asset searches filter the bundled list and are not sent to a server.
2. App data collection and sharing
This offline version does not transmit your preferences, watchlist, calculator inputs, or results to us or to market-data services. It has no account registration, advertising services, usage analytics SDK, or integrated third-party crash-reporting service. The app does not request access to contacts, location, camera, microphone, messages, or bank accounts. We do not sell app user data.
3. Content and third-party services
Displayed prices, changes, charts, market summaries, and exchange rates are simulations bundled with the app, not live market data. Learning articles are also bundled. This version does not connect to market APIs, exchanges, brokers, payment services, or news providers. Core features do not require an internet connection. Operating system and app store services have their own privacy policies.
4. If you contact support
If you email wdgz2789000@gmail.com, we receive your email address and information you choose to send, such as an issue description or screenshots. We use this information to respond to your request, address problems, and meet applicable obligations. Do not send passwords, wallet keys, or complete bank account details. The email provider, relevant access, and support-data retention and deletion arrangements are: The email service is Google (Gmail), which processes sender addresses, message content, attachments you send, and email metadata to provide email services. Correspondence is retained only as long as needed to handle requests, related follow-up, and applicable obligations. Access is limited to those who need to handle your request. You can request deletion using the support address. Google’s processing is also described in its Privacy Policy: Google Privacy Policy.
5. Retention and deletion
Local preferences remain until you change them or clear app data. On Android, open system Settings → Apps → WDGZ PRO → Storage → Clear data/Clear storage; labels vary by device. Uninstalling the app also removes its on-device app-data copy. There is no account-deletion button because the app does not provide accounts. We cannot erase local preferences remotely. The Android release disables app backup through platform configuration. Some device transfer or restore behavior can depend on the manufacturer and operating system; copies managed by device services are governed by those services and your settings. To request deletion of support correspondence you sent us, email wdgz2789000@gmail.com. Information may be retained when required by applicable law, with the reason and period explained when relevant.
6. Security
Local data uses app storage provided by the operating system. Device security, screen locks, system updates, and backup settings affect its protection. Access to support correspondence is limited to those who need it to handle requests. No storage or transmission method can be guaranteed completely secure.
7. Children
WDGZ PRO is a financial calculation and learning tool and is not directed at children. We do not knowingly request children's personal information through the app. If you believe a child has sent personal information through support, contact wdgz2789000@gmail.com so the request can be addressed.
8. Privacy questions and requests
Contact RIO ALEX SANRO DAMANIK at wdgz2789000@gmail.com with privacy questions or to request access, correction, or deletion of information you sent to support, in accordance with applicable rights. We may need limited information to verify the request. Data stored only on your device must be managed using that device.
9. Policy changes
If the app's data practices change, we will update this policy and its effective date with the relevant app version. Before adding online services, accounts, ads, analytics, or data providers, the relevant disclosures will be updated and notice or consent provided where required. To request the latest policy or ask about changes, contact wdgz2789000@gmail.com.
