Trust Wallet is a self-custody (non-custodial) wallet: your private keys and recovery phrase are generated and stored only on your own device, never on Trust Wallet's servers. That is the core of your security — and also your responsibility. This guide explains exactly how Trust Wallet protects your local data, where it does and doesn't keep you safe, and the practical steps to lock down your wallet on your own device.
How Trust Wallet Stores Your Data Locally
Non-custodial by design.Your private keys are generated on your device and never leave it. Trust Wallet has no access to your funds, keys, or personal data.
Local encryption.Sensitive data (your keys and recovery phrase) is stored on your phone encrypted with industry-standard encryption (AES-256), the same standard used by banks and governments.
On-device signing.Every transaction is signed locally on your phone. No server sees your key, which means a hacker cannot steal your coins remotely without physical access to your device.
No personal information required.You can create a wallet without submitting an email, phone number, or any personal data, reducing the amount of sensitive data stored on the device in the first place.
Open-source transparency.Trust Wallet's code is open source, which allows the community to audit that the app is not harvesting or sending your keys anywhere.
What "Local Data" You Need to Protect
| Data | What it is | How it's protected |
| --- | --- | --- |
| Recovery phrase (seed phrase) | 12 words that control your entire wallet | Encrypted locally; should never be stored digitally |
| Private keys | Derived from the phrase; sign every transaction | Encrypted locally on the device |
| Wallet addresses / balances | Public info for each enabled network | Stored locally, not sensitive on their own |
| Custom network / RPC settings | Your manually added network configs | Stored locally on the device |
Device-Level Protections You Should Enable
1. Set a wallet PIN / passcode.Trust Wallet lets you lock the app with a passcode so an unlocked phone alone is not enough to open your wallet.
2. Enable biometric unlock.Fingerprint and Face ID add a fast, strong layer on top of the PIN. Anyone with physical access to your phone still can't open the wallet without your biometrics.
3. Secure your phone itself.A screen lock (PIN, pattern, or biometrics) on the OS is your first line of defense — if the device is lost or stolen, a locked phone keeps your wallet closed.
4. Keep the OS and app updated.Updates include security patches. Running an outdated app or operating system leaves known vulnerabilities open.
5. Enable "Signing confirmation" / re-confirm before sending.Double-check transaction details (especially the recipient address) before confirming each transfer.
Backing Up Your Local Data Safely
Your local data can be wiped, lost, or damaged with the phone — so the recovery phrase is your true backup. Protect it as carefully as you protect the device:
Write the 12 words on paperand store it in a safe, dry, private place (ideally a fireproof safe). Consider two copies in different locations.
Never store the phrase in screenshots, notes apps, or cloud storage— any of these can be breached or synced.
Do not photograph the phrasewith your camera (photos end up in cloud backups).
Never enter the phrase into any website or appother than an official wallet on a trusted device.
What Trust Wallet Does NOT Protect (Threats You Must Handle Yourself)
| Threat | What to do |
| --- | --- |
| Phishing | Never enter your phrase on a website, "support" chat, or link sent to you. Verify the official app and domain yourself. |
| Malware / keyloggers | Only install Trust Wallet from the official App Store / Google Play. Keep your OS updated; avoid sideloaded apps. |
| Physical device theft | Lock the app with PIN + biometrics, and enable phone screen lock. |
| Cloud backup exposure | Exclude wallet data and any phrase screenshots from iCloud / Google Drive backups. |
| Sharing your phrase | Trust Wallet support will never ask for it. Anyone who does is a scammer. |
| Unverified custom networks / DApps | Only add networks and connect to DApps you trust; a malicious RPC or DApp can drain approvals. |
Best Practices: A Quick Checklist
1. PIN/passcode enabled on the wallet.
2. Biometric (fingerprint/Face ID) enabled.
3. Phone screen lock enabled.
4. Recovery phrase written on paper, stored offline and private.
5. No screenshots or cloud copies of the phrase anywhere.
6. App and OS kept up to date.
7. Wallet installed only from official app stores.
8. Transaction details double-checked before every send.
9. Cloud backup excludes wallet data.
10. Custom networks and DApps added only from trusted sources.
The Bottom Line
Trust Wallet protects your local data with strong local encryption and self-custody design — your keys never touch a server. But the two things that can still hurt you are physical access to an unlocked deviceand you sharing the recovery phrase. Enable the PIN and biometric locks, keep the phrase offline, and verify every website and DApp before interacting. Do that, and your local data stays exactly where it should: under your control.
