Key qualities
Overview
This technical overview is for readers who already understand the simple explanation and want to know how the app is built under the hood.
In tools like this, the key questions are what is encrypted, which components can see your secrets, how keys are generated and stored, and what diagnostic data is sent back to the vendor.
In a privacy-respecting security tool you typically see:
- Well-known, peer-reviewed cryptographic algorithms instead of custom crypto.
- Clear separation between encrypted user data and unencrypted account or billing data.
- Strong protection for keys (hardware security modules, secure enclaves, or client-side key storage).
- Minimal logging by default, with options to further reduce telemetry.
Why it matters for privacy: even if the marketing page sounds reassuring, the real protection comes from the technical design — how encryption, key management, networking and updates work together to reduce what attackers, insiders or governments can see.
Example: when evaluating a password manager, authenticator, or encrypted storage app, look for documentation or audits that explain which parts are end-to-end encrypted, how recovery keys work, and whether the company can ever decrypt your data on their servers.
