Terms & Conditions

Last updated: 24 March 2026

1. Introduction

GasMan Pro ("the App") is a professional productivity tool designed to assist gas engineers with record keeping, calculations, scheduling, invoicing, and documentation related to gas work.

The App is developed and provided by VibeTribe Studio Ltd (Company No. 17040308) ("we", "us", "our"), a company incorporated in England and Wales.

By downloading, installing, subscribing to, or using the App, you ("you", "the user") agree to these Terms & Conditions. If you do not agree, you must not use the App.

These Terms should be read alongside our Privacy Policy, which explains how data is handled on your device.

2. Eligibility & User Obligations

The App is intended for use by competent, appropriately qualified gas engineering professionals aged 18 or over.

By using the App, you confirm that you:

  • hold a valid Gas Safe registration (or equivalent qualification for your jurisdiction) where required by law
  • are solely responsible for verifying that your registration covers the categories of work you record in the App
  • will enter accurate and complete information
  • will review all documents generated by the App before issuing them to any third party
  • will keep your device physically secure and protected with appropriate access controls (PIN, biometrics, or password)
  • will comply with all applicable UK laws and regulations, including the Gas Safety (Installation and Use) Regulations 1998, Health and Safety at Work Act 1974, and the Building Regulations

You must not:

  • use the App for any unlawful purpose
  • reverse engineer, decompile, or disassemble the App
  • redistribute, resell, or sublicense the App or any content generated by it
  • remove or alter any proprietary notices within the App

3. Professional Responsibility

The App is a tool to assist you. It does not:

  • certify or approve gas work
  • validate compliance with regulations
  • replace professional judgement, training, or experience
  • verify the accuracy of data you enter

You are the issuer of every certificate, invoice, quote, warning notice, and document created using the App. The App generates documents based on the information you provide. You remain fully and solely responsible for:

  • all gas work carried out
  • all safety decisions made on site
  • the accuracy, completeness, and legal validity of every document you issue
  • compliance with all applicable laws, regulations, and industry standards
  • issuing documents to clients within any legally required timeframes (e.g. CP12 certificates to tenants within 28 days)
  • retaining records for legally required periods

Use of the App does not remove, reduce, or transfer any legal duties placed on you under UK law.

4. No Affiliation With Regulatory Bodies

GasMan Pro is not affiliated with, endorsed by, or connected to Gas Safe Register, the Health and Safety Executive (HSE), CORGI, or any other regulatory authority.

References to industry terms such as "CP12", "CP15", "CP16", "CP42", "CP44", or similar are descriptive only and reflect common industry usage. They do not imply any official status, approval, or endorsement.

All trademarks and regulatory authority remain the property of their respective owners.

5. Certificates, Records & Documentation

The App allows you to create, store, and export digital records and documents, including:

  • Gas safety certificates (e.g. CP12, CP15, CP16, CP42, CP44, CP2)
  • Domestic and commercial installation and commissioning records
  • Building regulations compliance records
  • Appliance and flue safety records
  • Warning notices (Immediately Dangerous, At Risk, Not to Current Standards)

Important

  • The App is a document generation tool. It does not issue, certify, or validate any document.
  • You are the issuer of every document. The legal validity of any certificate or record depends entirely on your competence, the accuracy of the information you enter, and your compliance with applicable regulations.
  • You must review every generated document for accuracy and completeness before issuing it to any third party.
  • We provide no warranty that generated documents meet the requirements of any specific regulation, standard, or authority.
  • Digital signatures captured within the App are your responsibility. You must satisfy yourself that digital signatures meet the legal requirements applicable to your work.

Record Retention

The App does not auto-delete safety records. However, record retention is your legal obligation. You are responsible for:

  • retaining gas safety certificates for a minimum of 2 years
  • retaining warning notices for a minimum of 6 years
  • complying with any other applicable retention requirements
  • maintaining backups of your records (see Section 11)

6. Warning Notices

The App allows you to create warning notices classified as:

  • Immediately Dangerous (ID) — indicating an immediate risk to life
  • At Risk (AR) — indicating a potential risk if the appliance continues in use
  • Not to Current Standards (NCS) — indicating non-compliance that does not present an immediate safety risk

The App does not enforce or verify the actions you are legally required to take when classifying an appliance. You remain solely responsible for:

  • correctly classifying defects
  • taking all required actions (including disconnection of Immediately Dangerous appliances)
  • notifying the relevant parties, including the customer and, where applicable, the Gas Safe Register
  • complying with the Gas Industry Unsafe Situations Procedure (GIUSP) and all other applicable safety procedures

  • gas rate calculator (metric and imperial)
  • pipe sizing calculator
  • unit converters (ft³/m³, MJ/kWh)
  • measurement and note-taking tools
  • scheduling and reminder tools
  • checklist templates
  • service interval calculators

All tool outputs:

  • are based entirely on data you enter
  • are provided for guidance and reference only
  • are estimates, not certified measurements
  • may not account for site-specific, appliance-specific, or environmental factors

You must independently verify all results before relying on them for any professional purpose. Tool outputs are not suitable for official records without independent confirmation by you.

We do not warrant that any calculation, conversion, or estimate produced by the App is free from error.

8. Invoices, Quotes & Financial Documents

The App allows you to create, store, and export invoices and quotes as PDF documents, including line items, VAT calculations, company details, and bank payment information.

Important

  • Invoices and quotes are generated based entirely on data you enter. You are solely responsible for the accuracy of all financial information, including pricing, VAT rates, VAT registration details, and payment terms.
  • The App performs VAT calculations automatically where you have enabled VAT. These calculations are provided as a convenience only. We do not provide accounting, tax, or financial advice. You must verify all VAT calculations independently and ensure compliance with HMRC requirements.
  • Quotes generated by the App may constitute offers capable of acceptance under contract law. You are responsible for the terms and validity of any quote you issue.
  • The App stores bank account details (sort code, account number, account name) locally on your device for inclusion on invoices. You are responsible for securing your device and ensuring this data is not exposed to unauthorised parties.
  • Payment tracking within the App (e.g. marking invoices as paid) is for your record-keeping only. It does not constitute official accounting or bookkeeping.

9. Email & Document Sharing

The App allows you to share documents (certificates, invoices, quotes, warning notices) via your device's built-in email client using Android's share functionality.

Important

  • Emails are sent from your own email account using your device's email application. We do not send emails on your behalf and have no access to your email account.
  • Pre-filled email templates (subject lines, body text) are provided as a convenience. You are responsible for reviewing and editing all email content before sending.
  • Documents shared via email may contain personal data (customer names, addresses, contact details). You are responsible for ensuring you have appropriate consent or lawful basis to share this information, in compliance with UK data protection law.
  • We are not responsible for the delivery, security, or interception of emails you send.

10. Notifications & Reminders

The App provides local on-device notifications to remind you of upcoming and overdue service appointments.

Important

  • Notifications are delivered on a best-effort basis only. Delivery depends on your device settings, battery optimisation, operating system behaviour, and other factors outside our control.
  • Notifications are not guaranteed and must not be relied upon as your sole method of diary or schedule management.
  • We are not liable for any missed appointments, overdue services, regulatory non-compliance, or other consequences resulting from notifications not being delivered or not being seen.
  • You remain responsible for managing your own professional schedule independently of the App.
