Why Relavoi

Privacy isn't a feature. It's the product.

Every call between your agents and customers routes through a temporary proxy number. When the job ends, the connection disappears.

Stop off-platform leakage

Drivers and customers can't take the relationship, or the revenue, off your app once the session expires.

No app on the customer's side

Calls run over Nigerian PSTN, so they reach any handset: smartphone or feature phone. No VoIP client, no data plan, nothing to install.

Privacy built in

Phone numbers AES-256-GCM encrypted at rest under per-tenant keys, never returned by the API, and never written to logs in plaintext.

For developers

One POST to your first masked call.

REST API, signed webhooks to your endpoint, and SDKs for iOS, Android and Flutter. Build against the sandbox before you touch a live number.
