Every component in Ringo was chosen with one goal: give kids the independence to communicate, and give parents the confidence that they're safe.
Every security layer in Ringo was designed specifically for a children's communication device — the bar is higher than a general consumer product.
Every Ringo has a unique ECC P-256 key generated inside the ATECC608B security chip at manufacturing. The key never leaves the chip — ever. A full flash dump cannot impersonate the device.
All calls use SIP/TLS for signaling and SRTP for audio. Voice notes are end-to-end encrypted — even the server has no keys. Your child's voice stays private.
A call to or from an unknown number is blocked locally on the device, blocked at the SIP server, and blocked by mutual pairing verification. Three independent layers. No gaps.
Unusual patterns — too many calls, repeated blocked attempts, volume spikes — trigger automatic throttling, parent alerts, or device suspension. Compromise of one device cannot spread.
Maximum blast radius: one household. Cross-household compromise is architecturally impossible without breaking hardware cryptography.
The Ringo parent app (iOS & Android) is how you set up, manage, and monitor your child's Ringo — from contacts to quiet hours to revocation.
Single, 2-pack, and 3-pack available. Free plan included. No contract.
