TETHER
Open dashboard
One card, contained.

A breach should cost you
one number, not your whole life.

Tether is a subscription tracker with a security spine. See every recurring charge in one place, get warned before a trial converts or a price climbs, and cut what you don’t want — in as close to one tap as the world allows.

Running in demo mode — the dashboard shows labeled sample data until bank linking is configured.

Tripwires

A heads-up before money leaves — price climbs, trials converting, new charges, duplicates, and the loud one: a charge after you cancelled.

Guided cancellation

There's no universal cancel button. Tether hands you the exact route per merchant — deep link, steps, pre-filled email — then watches that billing actually stops.

Leashes (Perimeter+)

Each subscription rides its own disposable card number. Snip the one that leaks; everything else keeps running. Your real card never moves.

The vocabulary is the product

TetherThe product. Each subscription is held on its own line, anchored to your real funding source but never exposing it.
LeashA virtual, merchant-locked card number issued for a single subscription. The merchant only ever sees the Leash, never your real card. (Phase 2.)
SnipKilling a Leash. One tap stops that subscription's billing instantly and permanently, with zero effect on any other Leash.
TripwireAn alert. Something crossed a line you care about — a price increase, a trial about to convert, a new recurring charge, a duplicate service.
DecoyWhat a thief actually walks away with. A skimmed or leaked Leash is worthless the moment you Snip it; your real card never moves.
