1.Who we are

sebbi.pro and AILeash are operated by Justin Antony Dobson, trading as Monop Content, Blyth, Northumberland, United Kingdom ("we", "us"). You can reach us at justin@monopcontent.com or through sebbi.pro/contact.

"You" means the person or organisation that opens the account. If you open an account for an organisation, you confirm you are allowed to bind it to these terms.

2.Agreeing to these terms

You agree to these terms when you open an account on sebbi.pro, when you use an API key, or when an AI assistant acting on your instructions opens an account for you (section 3). If you do not agree, do not use the service.

Every version of these terms has a version number and an effective date. The version in force when you agreed is the one recorded against your account.

3.Accounts opened by an AI assistant

You can connect an AI assistant (such as Claude, ChatGPT or Cursor) to sebbi.pro at https://sebbi.pro/mcp and have it set up your account.

4.Your account and API key

5.The free trial

Every product is free for 90 days from the day your account is opened. No card is needed to start. During the trial you have the full engine against your real traffic.

When the trial ends, the service pauses for your key until you add a card. Your key, your records and your device history are kept exactly as they were, and you carry on where you left off once billing is set up.

6.Price and billing

WhatPrice
All products50p per unique device per month after the 90-day trial. A device is a distinct device identifier that used your key in that month. There are no tiers and no minimum term.
Human KeysFor individuals, 50p a month for unlimited proofs, taken from your credit wallet and running for 30 days. For businesses, included in the per-device price.
Checking proofsFree, always. Verifying the chain, a block, a report digest or a Human Keys code costs nothing and needs no account.
Signal PacksWriting, reading, forking and publishing are free. Running a pack needs an API key.
Referrals10p per device per month, for as long as each referred device stays, paid to the holder of the referral code.

7.Cancelling

Stop using your key, or cancel your subscription in Stripe or by emailing us, at any time. Nothing further is charged after the end of the month in which you cancel. There is no cancellation fee.

If you are a consumer in the UK, you have 14 days from opening the account to change your mind. Because the service starts straight away and the trial is free, you will normally not have paid anything in that time.

8.The sealed record

The point of sebbi.pro is a record nobody can quietly change. Please understand what that means before you send us anything:

Do not send personal data into the chain. Use pseudonymous identifiers for people and devices (for example a hashed customer number, never a name, email address or phone number). Because the chain cannot forget, anything identifying you send into it stays there. Request details we record for the machine-proof report are kept off the chain and deleted after two years; only their fingerprints are sealed. See the Data Protection Statement.

9.Your data

How we handle personal data, what we deliberately never hold, how long we keep things and how to exercise your rights is set out in the Data Protection Statement, which forms part of these terms. Where we process personal data on your behalf, we do so only to provide the service you asked for.

10.Acceptable use

You must not use sebbi.pro to:

11.Your responsibilities

12.Signal Packs you publish

When you publish a Signal Pack, it becomes public, is sealed into the chain with you named as its author, and can be read and forked by anyone. You keep the credit for it. You give us and other users a free, worldwide, permanent licence to read, run, copy and adapt it within sebbi.pro. Do not publish anything you are not entitled to share.

13.Intellectual property

sebbi.pro, AILeash and our software, designs, documentation and names belong to us (see legal.txt). Your account gives you a licence to use the service for your own business while your account is active. Files we give you to run (such as the SDK or Sebdog) are licensed on the terms that come with them. Your data and your records belong to you.

14.The service

15.Liability

16.Suspension and ending

We may pause or close an account that breaks these terms, puts the service or other users at risk, or that we are legally required to act on. Where it is safe to, we will tell you first and give you a chance to put it right. You can close your account at any time. When an account closes, records already sealed stay in the chain (section 8); everything else is handled as set out in the Data Protection Statement.

17.Changes to these terms

We may update these terms. Each version gets a new number and date, and the changes take effect 30 days after we publish them, unless they are needed sooner for legal reasons. If you keep using the service after that, the new version applies. If you do not accept a change, you can cancel before it takes effect.

18.Law and disputes

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you are a consumer living elsewhere in the UK, you may also bring proceedings in your home courts. Please contact us first — most problems can be sorted out quickly.

The short version. Ninety days free. Then 50p per device per month, billed on real usage, cancel any time. Keep your key secret. Send pseudonymous data, because sealed records cannot be deleted. We record and prove; you decide, and you stay responsible for your own compliance.
