These Terms of Use ("Terms") are a legal agreement between you and Vladislavs Saperins, trading as Smart Business Labs ("we", "us"), England, United Kingdom. By downloading or using the SoleTax AI mobile application ("the App") you agree to these Terms. If you do not agree, do not use the App.
SoleTax AI provides general information only. It is not tax, financial, accounting or legal advice, and we are not regulated tax advisers, accountants or solicitors. AI-generated answers can be incomplete, out of date or wrong. You remain solely responsible for your Self Assessment return, tax payments and compliance with HMRC requirements. Always verify important matters with HMRC guidance or a qualified accountant before acting.
The App is designed for UK sole traders and individuals aged 18 or over. By using the App you confirm you meet these requirements.
The App provides general information about UK Self Assessment, National Insurance and allowable expenses, and includes tools for recording your income and expenses. Your financial records are stored locally on your device. Estimates and calculations produced by the App are indicative only and may not reflect your full tax position.
You agree not to: reverse-engineer, copy or resell the App; use it for unlawful purposes, including tax evasion; attempt to bypass subscription controls or overload our infrastructure; or use automated tools to extract AI responses at scale. We may suspend access for breach of these Terms.
How we handle information is described in the SoleTax AI Privacy Policy, which forms part of these Terms. You are responsible for backing up data stored on your device — uninstalling the App permanently deletes locally stored records.
The App, its design, branding and content (excluding your own records) are owned by us or our licensors. We grant you a personal, non-transferable, non-exclusive licence to use the App on your own devices for personal business purposes.
We aim to keep the App available but do not guarantee uninterrupted operation. We may update, modify or discontinue features. If we discontinue the App entirely, active subscriptions will be handled in line with Google Play policies and UK consumer law.
Nothing in these Terms excludes or limits liability that cannot be excluded under UK law, including liability for death or personal injury caused by negligence, fraud, or your statutory rights as a consumer under the Consumer Rights Act 2015.
Subject to the above: we are not liable for losses arising from your reliance on general information or AI-generated content in the App, including any tax underpayment, penalties, interest or missed deadlines; and our total liability to you in connection with the App is limited to the amount you paid us in subscription fees in the 12 months before the claim arose.
You may stop using the App at any time by uninstalling it. We may terminate or suspend your access if you materially breach these Terms.
These Terms are governed by the laws of England and Wales. Disputes are subject to the jurisdiction of the courts of England and Wales, without affecting your rights as a consumer to bring proceedings in your local courts.
