Frequently Asked Questions

RoadEcho is a privacy-first, secure digital messaging and notification utility designed to seamlessly bridge communication between vehicle owners using cryptographic plate hashing.

To ensure absolute compliance with the Driver's Privacy Protection Act (DPPA) and international privacy laws, raw license plate strings are transformed using SHA-256 cryptographic hashing with unique server-side salts. No raw plate numbers or plain-text Personally Identifiable Information (PII) are ever stored in the database.

No. RoadEcho operates on a strict zero-knowledge architecture, meaning the platform does not track, unmask, or reveal the identity or personal information of anonymous senders.

Senders look up a vehicle by state and plate, type or dictate a message via browser-native voice integration, and submit it with a mandatory terms agreement. All messages pass through real-time autonomous OpenAI pre-moderation filters to instantly intercept and block harassment, threats, or toxic language.

Any content flagged by the autonomous pre-moderation gate is automatically rejected and blocked from entering the vault queue. Your text stays in the form so you can reword it calmly and try again.

Vehicle owners can voluntarily claim up to three plate inboxes digitally via secure email authentication. Physical registration documents and government ID uploads are strictly prohibited to eliminate unnecessary PII liability.

You receive a unique referral link in your vault dashboard. When friends use your link to send a message or claim a plate, a 24-hour access pass is safely deposited into your stored pass vault.

Go to your dashboard vault, check your available stored passes, and click "Activate 24-Hour Pass From Vault" whenever you are ready to unlock waiting messages. Active time extends cleanly if you have remaining duration.

Fees paid on the platform strictly cover secure digital decryption, data delivery, and real-time alert services.
