1. Data Storage
All portfolio data — transactions, holdings, ticker resolutions, historical prices, exchange rates — is stored locally on your device. We do not collect, transmit, or store any personal information on external servers.
2. Network Access
The app connects to public financial data APIs solely to retrieve current and historical market prices and exchange rates. The following providers are used, and no user-identifying data is sent in any request:
- Yahoo Finance — primary stock and ETF prices. Public quote endpoints; no user-identifying data is sent.
- Twelve Data — fallback stock and ETF prices. Public quote endpoints; no user-identifying data is sent.
- CoinGecko — cryptocurrency prices. Public price endpoints; no user-identifying data is sent.
- NBP (Narodowy Bank Polski) — exchange rates for PLN pairs. Public daily rates; no user-identifying data is sent.
- ECB via Frankfurter.dev — exchange rates for EUR pairs. Public daily rates; no user-identifying data is sent.
Beyond the standard HTTP request metadata that any web request transmits to a server (such as your IP address and a generic User-Agent string identifying the Android system version), no app-side personal data is included in any of these requests, and Cyber Vault retains none of it.
3. Crash Reporting (Opt-in)
Cyber Vault includes Firebase Crashlytics, which is off by default. If you opt in via Settings → Crash reports, anonymous crash stack traces and your device model are sent to Google’s Firebase servers so problems get fixed sooner. No portfolio data, ticker symbols, financial values, or other identifying information are ever transmitted. You can revoke consent at any time in Settings; previously sent reports cannot be recalled but contain only the information described above.
4. Third-Party Services
Other than the data sources listed in Section 2 and the optional crash reporting in Section 3, this app does not use any analytics, advertising, or tracking services.
5. Data Deletion
You can delete all app data at any time by uninstalling the app or clearing app data through your device settings. Because all data is stored locally, this fully and irreversibly removes your portfolio from this app.
6. Disclaimers
The same disclaimers shown inside the app under Settings → Disclaimers also apply to the use of this app:
- Price data may be delayed. Prices on European exchanges may be delayed up to 15 minutes. Cryptocurrency prices may be delayed up to 60 seconds. Always verify with your broker before making investment decisions.
- Cyber Vault does not provide financial advice. Cyber Vault is a portfolio-tracking tool. It does not provide financial, investment, tax, or legal advice. All investment decisions remain your own responsibility. Consult a licensed professional before acting on information shown here.
- Data accuracy is not guaranteed. Prices and exchange rates are fetched from third-party providers (listed in Section 2). Cyber Vault makes no warranty as to their accuracy, completeness, or availability.
