Decionis Shield
Stop charges you didn't okay
Free
An unexpected charge, a subscription price increase, an AI agent that bought something — Shield holds it over your limit until you approve. Data Not Collected.
Stop charges you didn't okay. Decionis Shield holds a purchase, a renewal, or an AI agent's spend that goes over your limit until you say yes — and keeps a signed record of what it decided. Its App Store privacy label reads "Data Not Collected."
SET A SPENDING LIMIT, THEN FORGET IT
One rule per source: Allow, Ask Me, or Block, and a maximum spend. Marketplaces, apps, and AI agents start on Ask Me, so an approval needs you until you decide otherwise. Anything above your limit is held.
APPROVE A PURCHASE, OR DON'T
When something wants to spend past your limit — a subscription price increase, a renewal you forgot, an agent buying on your behalf — Shield holds it and asks. One tap with Face ID to allow it; one tap to keep it blocked.
SEE WHAT'S COMING
Coming Up separates the renewals and charges that are scheduled from the ones that are only estimated, so you can cancel a renewal before it charges instead of after.
WARN AT CHECKOUT
Pair Safari on this iPhone, or Chrome and Edge on your computer, and Shield checks the amount at checkout against your limits. It warns you and keeps the record; it cannot stop a payment for you.
DISPUTE A CHARGE WITH PROOF
Every held charge can become a Dispute Passport — a signed, shareable record of what was requested and what Shield decided, ready for the day you dispute a charge.
KNOW WHAT SHIELD DID THIS WEEK
Activity keeps the plain-language record; the weekly Shield Brief adds it up — held, approved, allowed automatically, and what renews next.
Shield holds or blocks spending only when it passes through a supported app, agent, or paired browser. Other activity may be visible, but Shield cannot stop it. No budgeting, no ads, no selling your data.
1.0.5: one-tap sign-in (code field always opens; code sent by Decionis Account), Spending sources, Add a renewal + radar, Bind your own agent, ASO rewrite; extension 1.0.4 with the sign-in fix
