These terms are between you and OKASHI SCHOOL LIMITED (company number 17085323, registered office 24 Hannay Lane, Alexander Court Bld, London, N8 9QQ), which supplies declownify. "You" means the person using declownify and the company they use it for. By installing or using declownify you accept these terms.

declownify is software that runs on your computer. It helps a UK micro-entity company:

• keep its books;
• prepare its Company Tax Return, accounts and computation;
• file them with HMRC.

The feature matrix describes what it supports. Do not use declownify for a company or a situation it does not support.

declownify is independent software. It is not provided by, endorsed by or affiliated with HM Revenue & Customs (HMRC) or Companies House, and it does not act on behalf of either.

HMRC does not recommend or endorse any one software product over another, and Companies House does not endorse or recommend particular products. HMRC does not support commercial software, so please take any question or difficulty with declownify to us, not to HMRC. HMRC does not carry out security testing of software products. The security statement explains how declownify protects your data.

declownify is not HMRC recognised. We will describe it as HMRC recognised only after HMRC's recognition process is complete. We never describe it as approved, accredited or certified by HMRC.

We grant you a non-exclusive, non-transferable licence to install and use declownify to prepare and file returns for companies you are authorised to act for. You may not resell it, or remove or change its notices. The software stays our property.

The return is yours. The company, and the person who makes the declaration, are responsible for the return being correct and complete. declownify computes figures from the books you keep and the rules it contains, but you must check them before you approve a return. If your affairs are complex, or declownify flags a point as uncertain, take advice from a qualified tax adviser.

You are also responsible for:

• Your books and evidence. Keep them complete and accurate. Keep the company's records, including HMRC's receipt for each return, for at least six years from the end of the financial year they relate to, or longer where the law requires.
• Approving and confirming. declownify submits a live return only after you have approved it, accepted HMRC's declaration and typed the live-submission consent. Do not give that consent unless you mean to file.
• Credentials. Keep your Government Gateway and Companies House credentials safe, and use only credentials you are entitled to use.
• Deadlines and payment. Filing and paying on time is your responsibility. declownify reminds you, but a missed or failed reminder does not change your obligations. You make tax payments yourself.
• HMRC's messages. Read every message HMRC returns. A return is filed only when HMRC has accepted it and declownify shows HMRC's receipt.
• Your computer. Keep its operating system up to date and keep full-disk encryption switched on.

Some features use services you choose and pay for yourself: your email account, your calendar, and the optional AI assistants (Claude Code, Codex CLI or Z.ai). Your agreements with those providers govern your use of them. We are not responsible for them.

declownify is supplied "as is". To the extent the law allows, we give no warranty that it is free of errors, that it will work without interruption, or that it suits your particular circumstances. HMRC's and Companies House's services may change or be unavailable, and declownify may need an update before it can file. Your statutory rights are not affected.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else the law does not allow to be limited.

Subject to that:

• we are not liable for tax, penalties, interest or surcharges arising from figures, approvals or payments that are your responsibility under section 4;
• we are not liable for loss of profit, business or data, or for indirect loss;
• our total liability under these terms is limited to the greater of the amount you paid us for declownify in the 12 months before the claim and £100.

We may release updates. Some, such as new HMRC schemas or tax rates, may be needed before declownify can file. You may stop using declownify at any time. Your data stays on your computer.

We will publish any change on https://tech.okashi.school with a new version number and date. Continuing to use declownify after a change means you accept it.

These terms are governed by the law of England and Wales, and its courts have jurisdiction.
