Decionis Shield · Money firewall
Your AI assistant can't spend what you haven't approved.
Assistants shop for you. Subscriptions renew themselves. Shield puts you back in charge: anything that wants to spend your money has to ask first — and anything over your limit is held until you say yes.
Free to start. No card required. Works in minutes.
Three minutes to a money firewall.
1. Connect what spends
Your assistants, subscriptions, and marketplaces — everything that can reach your money, in one list.
2. Set your limits
$25 per renewal. $100 per purchase. $50 a week for apps and AI. Your numbers, changeable any time.
3. Approve or block
Within your limits, life goes on. Over them, Shield asks — one tap to approve, one tap to block.
Made for the age of assistants that shop.
You told your assistant to find a gift, not to spend $400 on one. Shield gives apps and AI agents their own allowance — spend within it freely, ask you above it, blocked past the ceiling. The same for renewals that creep up and marketplace one-clicks at midnight.
- ✓A weekly allowance for apps and AI agents
- ✓Renewals held when the price jumps
- ✓Every held charge explained in plain words
- ✓A record of each decision, ready if you dispute a charge
Free to start. Pro when you want it all.

What does Shield actually stop?
Charges you didn't say yes to: an AI assistant buying something on your behalf, a subscription renewing at a price you forgot, a marketplace purchase over your limit. You set the limits; Shield asks you when something crosses them and holds anything higher.
Do I have to change how I pay?
No. You connect what's allowed to spend, set a limit per category — renewals, marketplace purchases, apps and AI agents — and keep living your life. Shield only interrupts you when something needs your yes.
Is it free?
Yes — Shield blocks surprise charges for free. Pro is $59.99 a year, cancel anytime, and removes the limits: unlimited Dispute Passports, custom protection limits, and protection across every connected platform.
What happens when Shield says no?
The charge is held, you get the reason in plain words, and you decide: approve it once, raise the limit, or keep it blocked. Every decision leaves a record you can show your bank if you ever dispute a charge.
How do I prevent subscription auto-renewal charges?
Set a per-renewal limit once — say $25 — and Shield holds any renewal above it until you approve. A price hike on a subscription you forgot stops being a surprise on your statement and becomes a question on your phone: this renewal wants $39.99, allow it?
