PRL Hub ("the app") is a self-custody cryptocurrency wallet and mining monitor for the Pearl ($PRL) network. We designed it to keep your data on your device. We do not collect, store, sell, or share any personal information.
No data collection
The app has no user accounts, no analytics, no advertising, and no third-party tracking SDKs. We — the developer — operate no servers that receive your personal data, and we have no way to identify you.
Your keys stay on your device
Your wallet recovery phrase and private keys are generated on your device and stored, encrypted, in the device Keychain / Secure Enclave. They never leave your device and are never transmitted to us. Viewing your recovery phrase or sending funds is protected by Face ID / Touch ID.
Third-party services the app contacts
To provide its features, the app makes direct requests from your device to public services. These requests carry only what is needed to fulfill them (for example a wallet or mining address you enter), and each service has its own privacy policy:
- Pearl blockchain indexer (
blockbook.pearlresearch.ai) — to read balances and broadcast transactions. - Public market data (e.g. SafeTrade public ticker, CoinGecko) — to display the $PRL price and charts, for reference only.
- Mining pool public APIs (AlphaPool, Lucky Pool, TW-Pool, HeroMiners, Pearl Fortune) — to show stats for a mining address you choose to monitor.
We do not control these services and receive no data from them.
iCloud sync (optional, Apple-encrypted)
If you use iCloud, your preferences (language, currency, pool setup) sync across your own devices through Apple iCloud. This data is handled by Apple under Apple's privacy policy; we have no access to it.
Children
The app is not directed to children and does not knowingly collect any information from anyone, including children.
Changes
We may update this policy from time to time. Material changes will be reflected on this page with a new "Last updated" date.
