Security tips
Keep your sensitive files safe
Short, practical guidance on authentication, privacy, storage, and the daily habits that keep your private documents and saved apps out of the wrong hands.
- AuthenticationHigh priority
Use a unique key for every vault
Never reuse the same rhythm or sound sequence across different apps or devices. A key that is unique to your SonicVault keeps one compromised account from cascading into every other place you store sensitive files. Treat your sound key the way you would treat a one-time passphrase: invented once, used nowhere else, and never shared.
- StorageHigh priority
Lock your device, not just your vault
Your sound key protects what is inside SonicVault, but the device itself is the first line of defense. Enable full-disk encryption and a strong screen lock on your phone or computer so that a lost or stolen device cannot be used to tamper with the app or its local storage before your vault is ever opened.
- AuthenticationHigh priority
Keep your recovery phrase offline
If you set a recovery passphrase, write it down on paper and store it somewhere physical and secure rather than in a notes app or cloud document. A recovery phrase stored digitally is only as safe as the weakest account that can reach it. Paper cannot be phished, synced, or leaked in a breach.
- Habits
Record your key in a quiet room
Background noise can distort the acoustic fingerprint your vault relies on. When you enroll a rhythm or sound sequence, pick a quiet environment with minimal echo so the recognition engine captures a clean signature. A key recorded in a noisy cafe will be harder to reproduce reliably and more prone to false rejections at unlock time.
- Privacy
Mind who is behind you when you unlock
A sound key is far harder to shoulder-surf than a typed password, but a determined observer can still try to learn your rhythm by watching your hands. When you unlock your vault in public, be aware of your surroundings and consider using the sound sequence method, which is harder to imitate from observation alone than a tapped rhythm.
- Habits
Review what you store regularly
Every few weeks, open your vault and remove files or saved apps you no longer need. Sensitive data you have deleted cannot be exposed in a future incident. Keeping only what is actively useful shrinks the surface area of what an attacker could reach if your device were ever compromised.
