Peace of Mind SMS

A text-message filter built on the ternary method: messages from numbers not in your contacts are judged one at a time as they arrive — scams, spam, and threats quietly diverted, threats preserved as evidence and alerted on, and you always know someone reached out.

CONCEPT VISUAL — Peace of Mind SMS Filter
Designed concept panel for a text-message filter — not a screenshot of a built or live service.

The goal

To protect a phone from scams, spam, and threats without reading the whole inbox — each unknown message judged on its own, with evidence preserved when it matters.

What it does — the task

  • Messages from numbers not in your contacts are judged one at a time as they arrive.
  • Scams, spam, and threats are quietly diverted.
  • Threats are preserved as evidence and alerted on.
  • You always know someone reached out — nothing vanishes silently.
  • Spec includes a 35-entry mobile-messaging threat registry and a production-hardening pass.
  • Privacy-first by design: judge one message, never read the inbox.

Protection

Unknown messages are judged as they arrive, so scams, spam, and threats are diverted before they reach you, while genuine contact still surfaces and threats are kept as evidence. Protection — varies by message volume

Status: Concept-design — full spec and threat registry exist; nothing built or live yet.
