01Who this is between
These terms are between BlocksUI Ltd, trading as Muster (“we”), and the organisation that opens an account (“you”). The person who opens the account confirms they are entitled to bind that organisation. If you are a volunteer acting for a committee, that means the committee has agreed.
02What the service is, and is not
Muster is software for keeping records of your public protection readiness under the Terrorism (Protection of Premises) Act 2025: scoping, the four procedures with version history, a register of people and their briefings, exercise and review logs, an SIA notification tracker, and an evidence pack that gathers the lot.
It is not legal advice, and it is not a certification service. Nobody can certify a premises as “compliant” with this Act, and Muster does not claim to. Using the service does not discharge any duty; the responsible person for the premises remains responsible for deciding whether the Act applies, which tier applies, and what the procedures should say. Our templates are starting points to be argued with, not answers.
The service currently covers standard tier only. It does not yet cover enhanced tier, vulnerability assessments, live alerting, hardware, CCTV or general fire and health-and-safety management, and we will not pretend otherwise. Enhanced tier is on our roadmap; if and when it ships, this clause will be updated to describe exactly what it covers. Until then, treat it as out of scope.
03Accounts and access
Creating an account is free. You can set up your organisation and first premises before paying, but a subscription is required to add or change records. Without an active subscription the account is read-only: you can still sign in, read every record and export everything. Nothing is deleted merely because you have not subscribed or because a subscription ends.
You are responsible for keeping your sign-in details private and for who you invite. Each person needs their own login; sharing one is how records rot, and we do not charge per person, so there is no reason to.
04Subscriptions and fees
The single-venue plan costs £14.99 a month or £149.90 a year, which is twelve months for the price of ten. All prices include VAT, because most of our customers cannot reclaim it and an ex-VAT price would be a smaller number that is not what you pay.
Payment is by card through Stripe, in advance, and renews automatically until cancelled. Umbrella arrangements for dioceses, trusts and councils are priced by written quotation against your list of sites and are governed by that quotation where it differs from these terms.
If a payment fails we will retry it and email you. If it still fails after a reasonable period the account becomes read-only as in clause 3, and no data is deleted until clause 13 applies.
05Founding-member pricing
Organisations that first subscribe on or before 5 April 2027 pay 50% less than the list price, and keep that discount for as long as the subscription remains continuously active. It survives switching between monthly and annual billing. It ends if the subscription is cancelled or lapses for non-payment and is later restarted, in which case the list price at that time applies.
The deadline is tied to the date the Act is expected to come into force. If that date moves we may extend the offer; we will not shorten it once published.
06Cancelling and refunds
You can cancel at any time from the billing page. You keep full access until the end of the period you have paid for, then the account becomes read-only. We do not give pro-rata refunds for the unused part of a period, except where the law requires it or where we have failed to provide the service.
First-payment guarantee. If you ask us at [email protected] within 14 days after first subscribing, we will cancel the subscription and refund that first payment in full. You do not need to give a reason. The guarantee applies to organisations as well as consumers, and does not limit any stronger right the law gives you. Refunds are returned to the original payment method.
A consumer may also have a statutory right to cancel a distance contract. Nothing in these terms removes or reduces that right, or your rights where the service is faulty, misdescribed or not supplied with reasonable care and skill.
07Your responsibilities
- The accuracy of what you record. The evidence pack reproduces what you entered; it cannot know whether a briefing actually happened.
- Deciding scope, tier and the content of your procedures, and taking professional advice where your situation is unusual. The scope checker cites its reasoning so you can check it against the legislation and the statutory guidance, and it says so when the law does not settle your case.
- Having a lawful basis to put your staff and volunteers on the register and to send them briefing requests. Under the data processing agreement you are the controller of that data.
- Keeping your contact details current so we can reach you.
08Acceptable use
Do not use the service to store data you have no right to hold, to send unsolicited email through the briefing feature, to probe or overload the service, or to do anything unlawful. Do not present anything Muster produces as an endorsement or certification by us or by any government body. We may suspend an account that does any of these, and will tell you why.
09Availability and support
We aim to keep the service available at all times and to fix faults promptly, but the single-venue plan carries no guaranteed service level. Planned maintenance is done outside UK working hours where we can and announced in advance where it will be noticeable. Support is by email at [email protected], normally answered within two working days.
10Your data
It stays yours. You can export everything, in open formats, at any time including after cancelling. We process it only as the data processing agreement and the privacy notice describe, and both form part of these terms. We may use aggregated, anonymised figures — how many premises use the checker, which outcomes are common — to improve the service and to describe it publicly. Nothing that identifies you or your people is ever used that way.
11Intellectual property
We own the software, the templates and the guidance text. You own what you write in them. You may reproduce the procedure templates for your own premises without limit, including after you leave; we would rather your procedures were good than that they were ours. You may not resell the service or the templates as a product.
12Liability
Nothing in these terms excludes or limits liability that cannot be excluded or limited by law, including for death or personal injury caused by negligence, or for fraud.
Subject to that, we are not liable for any loss arising from the content of your procedures, from a decision about scope or tier, from an inspection or enforcement outcome, or for any indirect or consequential loss. Our total liability to you in any twelve-month period is limited to the fees you paid us in the twelve months before the claim arose. The service is provided on a reasonable-endeavours basis and we do not warrant that it meets any regulatory requirement, because none currently recognises third-party products.
13Ending the agreement
You can close your account at any time. We can end it on 30 days’ notice, or immediately for serious breach of clause 8 or for non-payment after the retries in clause 4. Whichever way it ends, you have 30 days after the end of the final period to export your data, after which we delete it as the privacy notice describes.
14Changes, law and the rest
We may update these terms. If a change is material we will email account holders at least 30 days before it takes effect, and you may cancel before then if you do not accept it. The date at the top is the current version.
These terms are governed by the law of Scotland, and the courts of Scotland have jurisdiction, without prejudice to any right a consumer has to bring proceedings where they live. If any clause turns out to be unenforceable the rest still stand. These terms, the data processing agreement and the privacy notice are the whole agreement between us.
