Deadline Diary โ€” Terms of Service

Operated by GMS Suite Ltd

Last updated 23 July 2026 ยท Version 1.0

These Terms of Service ("Terms") govern your access to and use of Deadline Diary. Please read them carefully. By creating an Account, accepting these Terms during onboarding, or otherwise accessing or using the Service, you agree to be bound by them. If you do not agree, do not use the Service.


1. Parties and definitions

1.1 Parties

These Terms are a contract between:

Each is a "party" and together the "parties". Where an individual accepts these Terms on behalf of a firm or other organisation, that individual warrants that they have authority to bind it, and "you" means both that individual and that organisation.

1.2 Definitions

In these Terms, unless the context requires otherwise:

1.3 Interpretation

Headings are for convenience only. "Including", "in particular" and similar words are illustrative and do not limit what precedes them. "Writing" includes email and in-application electronic acceptance. The Schedules and any incorporated documents form part of these Terms.


2. The agreement, acceptance and consideration

2.1 Incorporation and acceptance

These Terms, together with the DPA and the Privacy Notice, form the entire agreement between the parties for the Service (the "Contract"). You accept these Terms when you set your Account password using the single-use link we email you at sign-up โ€” at which point you also accept the DPA and the Privacy Notice โ€” and by accessing or using the Service. We recommend you save or print a copy; we keep a durable record of the version you accepted and the date and time you accepted it.

2.2 Order of precedence

If there is a conflict between the documents making up the Contract, the following order of precedence applies, from highest: (a) the DPA, in respect of GMS's processing of personal data as your processor; (b) these Terms; (c) the Privacy Notice, in respect of GMS's processing of personal data as a controller.

2.3 Consideration

These Terms are supported by valuable consideration, comprising (as applicable) your payment of any Fees and, in every case, your provision of Customer Content, your acceptance of the obligations, licences, warranties and indemnities in these Terms, and the parties' mutual promises. Where the Service is provided without a monetary charge, these Terms are nonetheless a binding contract.

2.4 Business customers only

The Service is provided for use by businesses, professionals and firms (in particular accountants, bookkeepers and other advisers) in the course of their trade, business, profession or craft. It is not intended for, or offered to, consumers, and you confirm that you are accepting these Terms in the course of a business, profession or firm. Accordingly, the Consumer Rights Act 2015 does not apply to the Contract, and these Terms are subject to the Unfair Contract Terms Act 1977.


3. Service description

3.1 What the Service does

You organise the companies you want to monitor into one or more named Watchlists, and you set โ€” separately for each Watchlist โ€” the alert cadence (daily, weekly or off), the change types you want to be told about (such as annual accounts, confirmation statement, director/PSC identity verification, company status and other details), and how far ahead of each deadline you want to be warned.

The Service reads publicly available information from the Register for the companies you choose to monitor, and:

3.2 What the Service reports

The Service reports what the Register shows. It reads and relays published data and detects changes to it. It does not determine, calculate, certify, guarantee or advise on any company's compliance status, and it does not file anything with Companies House or any other body.

3.3 Officer data is fetched live, not stored

Director and PSC information (including names and identity-verification status) is retrieved from the Register live at the time you view a company and is not written to disk by the Service. The Service stores only company numbers, your labels, and company-level snapshots consisting of dates and status values (which do not contain individuals' names), as needed to detect changes.

3.4 Scope and evolution

The Service currently covers UK companies. Irish (CRO) monitoring may be made available in future; until we confirm it is live, Irish companies added to a Watchlist are shown as pending and are not monitored. We may add, change or remove features from time to time in accordance with clauses 10 and 14.


4. Nature of the Service: a monitoring aid, not advice

This clause 4 defines what the Service is and is not. You accept the Service on this basis, and it governs how the Service is to be understood and relied upon.

4.1 A monitoring and alerting aid

The Service is a monitoring and alerting aid. It is not accounting, bookkeeping, tax, legal, audit, company-secretarial or compliance advice, and it does not create any advisory, fiduciary or professional-client relationship between you and GMS. GMS is not your accountant, auditor, solicitor or agent, and does not undertake to advise you.

4.2 The Register is authoritative

The Register maintained by Companies House is the sole authoritative source of the information the Service reports. Where anything shown or sent by the Service differs from, conflicts with, is more or less current than, or is absent from the Register, the Register prevails. You must verify the position directly with the Register before taking, or refraining from, any action that has legal, regulatory or financial consequences.

4.3 You remain responsible

You remain solely responsible for:

The Service files nothing on your behalf, extends no deadline, and does not discharge or reduce any obligation you or your clients owe. The Service supports your professional judgment; it does not replace it, or replace checking the Register.

4.4 No guarantee of detection, timeliness or delivery

We do not warrant or guarantee that the Service will detect every change, detect any change accurately or in time, or deliver any Alert. Alerts depend on data published by Companies House and on third-party email delivery, neither of which is within our control, and on the cadence and settings you choose (including turning Alerts off). Absence of an Alert does not mean nothing has changed, and receipt of an Alert does not mean that every change has been captured. You must not treat the Service as a complete or fail-safe compliance system.

4.5 Basis of dealing

The way the Service is defined in this clause 4 is a fundamental basis on which GMS provides it, is reflected in the terms on which it is offered (including that it is currently free), and is reasonable having regard to the nature of the Service described in clause 3. This clause describes the scope of what GMS provides; the allocation of liability for that scope is set out in clause 12.


5. Accounts, eligibility and security

5.1 Creating your Account

Sign-up is self-serve. You provide your name and work email; we email you a single-use link; and clicking that link โ€” which confirms the mailbox is yours โ€” lets you set a password and accept these Terms, the DPA and the Privacy Notice. You must provide accurate registration details and keep them up to date. We may suspend or withdraw an Account in accordance with clause 13, including where required by law or by Companies House.

5.2 Credentials

You are responsible for keeping your Account credentials confidential and for all activity under your Account. You must choose a password meeting our stated minimum strength, must not share your credentials, and must notify us promptly at hello@simplinuity.com if you suspect any unauthorised access. If you forget your password, you can reset it yourself using the self-serve reset. Subject to clause 12, we are not liable for loss arising from your failure to keep your credentials secure.

5.3 One firm, appropriate use

An Account is for use by you and, where you are a firm, your authorised personnel acting for the firm. You must not permit access by anyone else, or operate the Account as a bureau for third parties, except as permitted by clause 8.


6. Intellectual property and licence

6.1 Our IP

The Service, and all software, code, designs, text, layouts, logos, trade marks and other materials comprising it (excluding Customer Content and Register data), are owned by GMS or its licensors and are protected by intellectual-property rights. Nothing in these Terms transfers any such rights to you.

6.2 Licence to you

Subject to your compliance with these Terms, GMS grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to access and use the Service for your internal business purposes during the term of the Contract. All rights not expressly granted are reserved.

6.3 Your Content

You retain all rights in Customer Content. You grant GMS a non-exclusive, worldwide, royalty-free licence to host, store, copy, process and transmit Customer Content to the extent necessary to provide, secure and maintain the Service and to comply with law. To the extent Customer Content contains personal data that GMS processes as your processor (your Watchlists), GMS's use of that personal data is governed by, and limited to the purposes permitted by, the DPA and clause 9.3; the licence in this clause does not authorise GMS to use that Watchlist personal data to develop or improve the Service, except to the extent the DPA expressly permits (for example, the creation and use of aggregated or anonymised data that is no longer personal data). GMS may use other Customer Content, and aggregated or anonymised data derived from the Service, to secure, maintain and improve the Service.

6.4 Register data

Data sourced from the Register is used by GMS as permitted by Companies House and applicable licensing. You must not use Register data obtained through the Service otherwise than as permitted by law and by Companies House's terms of use.

6.5 Feedback

If you give us feedback or suggestions, we may use them without restriction or obligation to you.


7. Your obligations and warranties

You represent, warrant and undertake, on each occasion you use the Service, that:

7.1 Authority and lawful basis to monitor

You are entitled to add and monitor each company number you enter; doing so is for a legitimate professional purpose; and it breaches no obligation of confidentiality, contract or law owed by you (including to your clients). Where any Customer Content constitutes personal data, you have a valid lawful basis under the UK GDPR for the processing you instruct GMS to carry out on your behalf, and you have obtained or given any notices and satisfied any conditions required for that processing.

7.2 Your own transparency duties to your clients

You are responsible for your own duties as a controller towards your clients and any individuals whose data your use of the Service involves, including the duty to provide privacy information under Articles 13 and 14 of the UK GDPR. GMS's Privacy Notice covers only GMS's own processing as a controller; it does not discharge, and you must not rely on it to discharge, your transparency or other data-protection obligations to your clients.

7.3 Accuracy of Customer Content

The company numbers and other data you upload are your responsibility. The Service relies on the accuracy of the numbers you provide; an incorrect, mistyped or outdated number will cause the Service to monitor the wrong company or nothing at all. You are responsible for verifying that each number corresponds to the company you intend to monitor.

7.4 Professional responsibility

Where you are a member of, or regulated by, a professional body, you remain fully responsible for meeting your professional and regulatory obligations. Your use of the Service does not modify, reduce or satisfy those obligations, and you must not represent to any client or third party that it does.

7.5 Compliance with law

You will use the Service in compliance with all applicable laws, including data-protection and anti-money-laundering law, and will not use it to infringe the rights of any person.


8. Acceptable use

You must not, and must not permit any person to:

We may investigate suspected breaches and may suspend or terminate access under clause 13. You will not use the Service in a way that risks GMS's own access to Companies House data or breaches Companies House's terms.


9. Data protection

9.1 Three data relationships

The parties acknowledge that the Service involves three data relationships:

9.2 Compliance

Each party will comply with the Data Protection Laws in respect of its own processing. GMS's processing of Watchlist personal data on your behalf is governed by the DPA, which prevails over these Terms to the extent of any conflict on that subject. Nothing in the Contract limits or excludes: (a) either party's liability to a data subject under Article 82 of the UK GDPR (a statutory right to compensation that cannot be affected by a contract to which the data subject is not a party); or (b) any liability of either party to the Information Commissioner (or any successor regulator, including the Information Commission established under the Data (Use and Access) Act 2025) under the enforcement and penalty provisions of the UK GDPR and the Data Protection Act 2018. Liability of the kinds in (a) and (b) cannot be limited or excluded by agreement. This clause does not prevent the parties from allocating liability between themselves, or from exercising any right of contribution or recovery under Article 82(5) of the UK GDPR, in each case subject to clause 12.

9.3 No secondary use

GMS will not use Watchlist personal data for any purpose other than providing the Service on your instructions and as permitted by the DPA. Any future advertising-supported or data-monetisation model will be introduced only on terms consistent with GMS's processor role over the Watchlist and with the Privacy Notice, and, where it would materially change how personal data is used, only on notice under clause 14 and, where required, with a renewed lawful basis and updated notices.


10. Fees and changes to pricing

10.1 Current provision

The Service is currently provided free of monetary charge, on an "as is" and "as available" basis, with no service-level commitment. Providing the Service without charge does not reduce either party's obligations under data-protection law or these Terms.

10.2 Future charges and tiers

We may, on at least 30 days' prior notice given under clause 14, introduce charges, paid plans, usage limits or an advertising-supported tier, or change any of them. If you do not accept a new charge, your remedy is to stop using the Service and, where relevant, close your Account before the change takes effect; continued use after the change takes effect constitutes acceptance.

10.3 Where Fees apply

Where Fees apply, they are payable in advance unless stated otherwise, are exclusive of VAT (which you will pay where chargeable), and are non-refundable except as required by law or expressly stated. We may suspend the Service for non-payment after notice.


11. Indemnity

11.1 Your indemnity

You will indemnify and hold GMS harmless against all losses, liabilities, damages, costs and expenses (including reasonable legal costs) that GMS reasonably incurs arising out of or in connection with:

11.2 Conduct

GMS will notify you promptly of any claim to which the indemnity applies, will not settle it without your consent (not to be unreasonably withheld), and will give you reasonable assistance (at your cost) in dealing with it. This indemnity is subject to clause 12.1 (non-excludable liabilities) but is not subject to the cap in clause 12.3, which limits GMS's liability to you and not yours to GMS.


12. Limitation of liability

This clause 12 allocates risk between the parties and should be read in full. Some liabilities cannot lawfully be excluded, and these Terms do not exclude them (clause 12.1). The remaining limits are a reasonable allocation of commercial risk.

12.1 Liabilities we do not exclude

Nothing in these Terms excludes or limits GMS's liability for:

12.2 Loss we exclude

Subject to clause 12.1, GMS is not liable, whether in contract, tort (including negligence), breach of statutory duty or otherwise, for any:

in each case even if the loss was foreseeable and even if GMS was advised of the possibility of it. The losses in (a)โ€“(d) are risks that you can and should insure against and manage through your own compliance processes, consistent with the responsibility you retain under clause 4.3 and with the nature of the Service as a monitoring aid (clause 4).

12.3 Overall cap

Subject to clauses 12.1 and 12.2, GMS's total aggregate liability arising out of or in connection with the Contract (including the DPA, save for liabilities within clause 12.1) in any 12-month period is limited to the greater of:

This cap is a reasonable allocation of risk, having regard to the nature of the Service as a monitoring aid whose output you verify against the authoritative Register (clause 4), the price of the Service, and your ability, as a professional, to manage and insure compliance risk through your own processes and cover.

12.4 Independent provisions

Each exclusion and limitation in this clause 12 operates independently. If any is held to be unenforceable or unreasonable, that does not affect the enforceability of the others, which continue to apply.

12.5 Insure your own risk

You acknowledge that the excluded and capped losses are risks best borne and insured by you, and you are strongly advised to maintain adequate professional indemnity and other insurance appropriate to your business.

12.6 Your liability

Nothing in this clause 12 limits your liability to pay Fees when due or to indemnify GMS under clause 11.


13. Suspension and termination

13.1 Termination by you

You may stop using the Service at any time, and you may close and delete your Account yourself from your Account settings. You can also export your Customer Content from your Account settings before you do.

13.2 Termination by us

Either party may terminate the Contract on 30 days' written notice. We may, in addition, suspend or terminate your access immediately, on notice, if: (a) you materially breach these Terms (including clauses 7 or 8) and, where the breach is capable of remedy, fail to remedy it within 14 days of notice; (b) we are required to do so by law or by a regulator; (c) Companies House withdraws or restricts our access to Register data; or (d) we reasonably believe your use poses a security, legal or operational risk.

13.3 Effect of termination

On termination, your licence under clause 6.2 ends and your access ceases. Your data is deleted or returned as described in the Privacy Notice and, for Watchlist personal data, the DPA; we may retain a minimal record that you accepted these Terms (which version, and when) for the purpose of establishing or defending legal claims. Termination does not affect any accrued rights or liabilities.

13.4 Survival

Clauses 1, 4, 6.1, 6.3, 6.4, 6.5, 7, 9, 11, 12, 13.3, 13.4, 15, 16, 17 and 18, and any provision that by its nature should survive, survive termination.


14. Changes to these Terms

14.1 Right to change

We may change these Terms, the Service, and (subject to clause 10) the Fees, from time to time โ€” for example to reflect changes in the Service, in law, in our sub-processors, or in our monetisation model.

14.2 Notice and re-acceptance

We will give you reasonable notice of any material change (normally at least 30 days), by email to your Account address and/or in the Service. Where a change is material, we may require you to accept the updated Terms before you continue to use the Service, and we will record that renewed acceptance. Non-material changes take effect on posting. Your continued use of the Service after a change takes effect constitutes acceptance of it; if you do not accept a change, your remedy is to stop using the Service and close your Account.


15. Dispute resolution and escalation

15.1 Good-faith escalation

If a dispute arises out of or in connection with the Contract, the parties will first try to resolve it in good faith. Either party may escalate by written notice describing the dispute, and each party will nominate a senior representative to meet (in person or remotely) within 14 days of the notice to seek resolution.

15.2 Mediation

If the dispute is not resolved within 30 days of the escalation notice, the parties will consider referring it to mediation under the CEDR Model Mediation Procedure before commencing court proceedings. Nothing in this clause requires the parties to mediate where one party reasonably considers mediation inappropriate.

15.3 No bar to proceedings or urgent relief

This clause does not prevent either party from commencing court proceedings, and does not restrict either party's right to seek urgent interim or injunctive relief at any time, including to protect Confidential Information or intellectual-property rights.


16. General

16.1 Confidentiality

Each party will keep the other's Confidential Information confidential and use it only for the Contract, except where disclosure is required by law or regulator, or the information is or becomes public other than through breach. This clause does not restrict GMS's processing of personal data under the Privacy Notice or the DPA.

16.2 Force majeure

Neither party is liable for failure or delay in performing its obligations (other than payment) caused by events beyond its reasonable control, including failures of Companies House, internet or email infrastructure, hosting providers, or acts of government. This does not limit your obligation to meet your own statutory deadlines, which are yours alone (clause 4.3).

16.3 Assignment

You may not assign, transfer or sub-contract the Contract without our prior written consent. GMS may assign or transfer the Contract to an affiliate or in connection with a reorganisation, merger or sale of its business, on notice to you.

16.4 Entire agreement and non-reliance

The Contract is the entire agreement between the parties on its subject matter and supersedes all prior discussions, representations and agreements. Each party agrees that it has not relied on, and (save as set out below) has no remedy for, any statement, representation or warranty not set out in the Contract. This clause operates as an agreed basis of dealing and does not exclude or restrict any liability more than the law permits; to the extent it excludes or restricts liability for misrepresentation, it is subject to section 3 of the Misrepresentation Act 1967 and the reasonableness test of the Unfair Contract Terms Act 1977. Nothing in this clause limits liability for fraud or fraudulent misrepresentation.

16.5 Severance

If any provision of the Contract is or becomes invalid, illegal or unenforceable, it is to be deemed modified to the minimum extent necessary to make it valid, or, if that is not possible, deemed deleted; the rest of the Contract is unaffected.

16.6 Waiver

No failure or delay in exercising a right is a waiver of it, and no single or partial exercise prevents further exercise.

16.7 No partnership or agency

Nothing in the Contract creates a partnership, joint venture, agency or employment relationship between the parties.

16.8 Notices

Notices to GMS must be sent to hello@simplinuity.com (and, where these Terms require writing, are validly given by email). Notices to you may be sent to your Account email address. Notices are deemed received on the next business day after sending by email.

16.9 Third parties

A person who is not a party to the Contract has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any of its terms. The companies and individuals you monitor, and your own clients, acquire no rights against GMS under the Contract.


17. Governing law and jurisdiction

The Contract, and any dispute or claim (including non-contractual disputes or claims, such as a claim in tort or for misrepresentation) arising out of or in connection with it or its subject matter or formation, are governed by the law of England and Wales. The parties submit to the exclusive jurisdiction of the courts of England and Wales.


18. About us and contact

The Service is operated by GMS Suite Ltd, a company registered in England and Wales (registered number and registered office on the public register at Companies House), ICO registration ZC130423. For any question about these Terms, contact hello@simplinuity.com.

Version 1.3
