TRXBest Wallet ("the App") is a non-custodial TRON wallet. Our design principle is simple: your keys and data belong to you, and we collect as little information as possible.
1. What we do not collect
- Recovery phrases and private keys: stored only in your device Keychain and never uploaded to our servers.
- Identity information: the App has no account system and does not collect names, phone numbers, or identity documents. An email address is collected only if you type one into the support chat yourself — see section 5.
- Advertising and tracking: the App contains no third-party analytics, advertising, or tracking SDKs and does not track you across apps or websites. It sends anonymous first-party usage statistics to our own server — see section 6. It also embeds a customer-support SDK, which sends data only when you open the support chat — see sections 5 and 8.
- PIN and biometrics: PIN data stays on device as a salted hash. Face ID and Touch ID are handled by iOS; the App cannot access biometric data.
- Exception: if you opt in to incoming-transfer notifications, public wallet addresses and a push token are uploaded — see section 4.
2. Necessary network requests
- Blockchain data: querying balances, resources, and transaction history uses public TRON node services such as TronGrid. Blockchain activity is public by nature.
- Broadcasting transactions: signed transaction data may be sent to public TRON node services for broadcasting. Private keys are not sent.
- Energy rental configuration: the App may request provider configuration used for TRON energy rental. This does not create an account and does not involve exchange services.
3. Cryptocurrency exchange services
The App does not provide buy, sell, swap, conversion, trading, centralized exchange, decentralized exchange, fiat on-ramp, fiat off-ramp, brokerage, new-token, staking, yield, or investment-advice services. TRON energy rental is a network-resource utility and does not exchange one cryptocurrency for another.
4. Incoming-transfer notifications (optional, off by default)
Only after you turn on Settings → Notifications → Receive Notifications does the App send the following to our server, so it can alert you to incoming TRX or USDT while the App is closed:
- Public wallet addresses: used to watch those addresses for incoming transfers on-chain. Wallet addresses are public blockchain data.
- APNs device token and an anonymous install identifier: used to deliver the notification to your device. The identifier is randomly generated by the App, is not linked to any identity, and is not used for tracking.
- App version, build number, and language preference: used to localize notification text and to troubleshoot.
Recovery phrases, private keys, PINs, balances, and transfer amounts are not uploaded. Amounts shown in a notification are rendered locally on your device.
Retention and deletion: turning the notification toggle off asks the server to delete these subscription records. Records inactive for 90 consecutive days are purged automatically.
5. In-app support chat (optional, only when you start it)
The App includes an in-app support chat powered by Crisp (Crisp IM SAS). Nothing is sent to it until you open the chat yourself. When you do, the following is attached so support can help you without interrogating you:
- Your messages and any files you attach, plus an anonymous session identifier randomly generated on your device. It is not linked to any identity and is discarded when you delete the App.
- App and device context: app version, iOS version, device model, language, selected network, number of wallets, available energy and bandwidth, and the range your balance falls into — never the exact amount.
- Transaction context, only when you start the chat from a specific transfer or rental: its status, amount, on-chain transaction hash, and a shortened form of your wallet address (for example TUEZSd…WYdH).
- An email address only if you choose to enter one in the chat so we can reply after you close the App.
Recovery phrases, private keys, PINs, exact balances, and your full wallet address are never sent. Support will never ask you for them — anyone who does is attempting theft.
Retention and deletion: transcripts are stored by Crisp on our behalf so we can trace how an issue was handled. Write to [email protected] to have yours deleted.
6. Anonymous usage statistics
To understand which features are used and where people get stuck, the App sends anonymous usage events to our own server (no third-party service), for example: which screens were opened, whether a transfer was confirmed or failed, whether rented energy arrived and roughly how long it took.
- What is sent: event names, the anonymous install identifier described in section 4, App version, and coarse categories such as the token type (TRX / USDT), an amount range (for example “10–100”), or a duration range.
- Never sent: wallet addresses, transaction hashes, exact amounts or balances, recovery phrases, private keys, PINs, clipboard contents, or support-chat messages.
- Not used for tracking: the data is not combined with data from other companies, is not used for advertising, and is not linked to your identity.
- Retention: raw events are deleted after 60 days; only aggregated daily totals are kept.
- Opting out: write to [email protected] (support can find your install identifier in the chat) and we will stop accepting usage events from your device.
7. Local storage and deletion
Wallet addresses, transaction caches, provider settings, and rental records are stored locally on your device. Deleting a wallet in the App or deleting the App removes the local app data from that device. Always back up your recovery phrase; because the App is non-custodial, nobody can recover assets for you if it is lost.
8. Third-party services
The App relies on public TRON node services such as TronGrid for on-chain data access. The in-app support chat is provided by Crisp (Crisp IM SAS) and is covered by Crisp's privacy policy. No third-party analytics, advertising, or tracking SDKs are integrated; usage statistics (section 6) go only to our own server.
9. Children
The App is not directed to children under 18.
10. Changes and contact
Updates to this policy will be posted on this page. Questions can be sent to [email protected].
