Terms and conditions
Last updated 14 July 2026.
These terms apply when you use Monk, a service of Welsenes Brothers V.O.F., Nieuwe Prinsengracht 92-2, 1018VW Amsterdam, the Netherlands (KVK 77647157). Using Monk means you agree to them.
What Monk does
Monk finds the ads winning in your market and generates new ones in your brand. It reads your Meta ad data and the public Meta Ad Library. It never posts ads and never spends your budget.
Your account
You need an account to use Monk. Keep your sign-in details to yourself, and tell us if you think someone else has access. You are responsible for what happens under your account.
Trial, price and cancelling
- New accounts get a free trial. No card is needed to start it.
- Prices are on the pricing section of our site. Founding brands keep their price for their first 12 months.
- You can cancel at any time, and you keep access until the end of the period you already paid for. We do not refund part-months, apart from any guarantee we have given you in writing.
- Payments are handled by Stripe. We never see your card details.
Fair use
Do not use Monk to break the law, to infringe someone else’s rights, or to attack the service. Do not resell it as your own.
Your content and your ads
Your brand, your inputs and the ads Monk generates for you are yours. You give us permission to process them only so we can run the service for you. Check every ad before you launch it: you are responsible for what you publish, including whether it follows Meta’s advertising rules.
Third parties
Monk depends on services we do not control, including Meta and Higgsfield. If they change or go down, parts of Monk may stop working. We will do our best, but we cannot promise those services will always be available.
What we do not promise
Monk helps you find and make better ads. It does not guarantee any particular result, ranking or return on your ad spend. The service is provided as it is.
Liability
We are not liable for indirect or consequential loss, including lost profit or lost ad spend. Where we are liable, it is capped at what you paid us in the 12 months before the claim. None of this limits liability that cannot be limited by law.
Changes
We may update these terms. If a change matters to you, we will tell you by email before it takes effect.
Law
Dutch law applies. Disputes go to the competent court in Amsterdam, the Netherlands.
