Terms of Use

Last updated 3 October 2026

MyBuildTool is a product of Arity Craft Limited, a company registered in the Republic of Mauritius at Coastal Road, Suite 005, Grand Baie Business Park, 30515, Grand Baie, Republic of Mauritius. In these terms “we” and “us” mean Arity Craft Limited. By using the application you agree to these terms.

What the service does

MyBuildTool turns measurements into material quantities for construction and renovation work — paint, concrete, tiles, flooring and project costs. With an account you can save those calculations into projects and open them again later.

Estimates are not advice

The figures MyBuildTool produces are calculations based on the numbers you enter and the assumptions shown alongside each result. They are not professional, engineering, building-control, financial or legal advice. Materials, site conditions, local regulations and supplier packaging vary, and you remain responsible for checking any quantity before you order it and any figure before you quote it.

We never invent a price. Costs appear only when you enter your own, and every coverage rate, waste factor and mix ratio used in a result is shown with its source so you can judge it for yourself.

Accounts

The calculators work without an account, and always will. To save projects you need one, and you are responsible for keeping your sign-in details secure and for what happens under your account. You must be old enough to enter a contract where you live.

Plans and pricing

Free — every calculator, with or without an account. A free account saves up to 3 projects.

Pro — a paid subscription, monthly or yearly. It includes unlimited saved projects, project history, shopping lists, cost estimates and PDF export.

The currency you choose inside the application affects how your own estimates are displayed. Your own figures are never converted: a price you enter and a total we calculate from it stay in the currency you entered. The current plans are always on the pricing page.

Billing and payment

Pro subscriptions renew monthly or yearly at the price you choose at checkout until canceled. Paddle shows any applicable tax before you confirm payment and acts as merchant of record. A promotional code, where we offer one, applies only on the terms shown at checkout. Nothing is charged until you choose a plan and complete checkout. Manage or cancel a subscription from Settings. Cancellation stops future renewals and keeps paid access through the period already paid for.

Pro is USD 100 a month or USD 996 a year — USD 83 a month paid yearly. You choose the period at checkout, and you can cancel from Settings at any time.

Subscriptions are charged in USD. If your card is in another currency, your bank or card issuer applies its own exchange rate and may add its own fee, and the price in USD is the one that governs. The price and renewal terms shown at checkout apply only when you accept them.

What happens if you do not continue with Pro

When a subscription ends, your account moves to read-only Free access. You can still sign in and read your existing projects, calculations and shopping lists, but cannot save, edit or delete them while the account remains read-only.

Restoring Pro removes the downgrade restriction and gives you normal access to the same saved work. A separate restriction for misuse is not removed by subscribing. You may still ask us to delete your account and its data.

Refunds

For a paid subscription, you can ask for a full refund within 14 days of a payment. You do not need to give a reason.

How to ask, and what happens to your account afterwards, are in the Refund Policy. A refund would be returned by Paddle to the card or account you paid from. If something has gone wrong with a payment, contact admin@aritycraft.com and we will look at it.

Sales are made through Paddle, our payment processor and merchant of record.

Your data

What we collect and why is set out in our Privacy Policy. In short: if you calculate without an account we store nothing at all. If you sign up we store your account details so we can identify you, and the projects and calculations you save. We do not collect banking details unless you consent to a subscription, and even then they are handled by Paddle rather than by us. You can ask us to delete your account and its data at any time and we will remove it.

Acceptable use

Do not use MyBuildTool for anything unlawful, do not try to disrupt or overload it, do not attempt to reach data that is not yours, and do not resell access to it. We may suspend an account that does.

Availability and liability

The service is provided “as is”. We work to keep it available and accurate but do not guarantee uninterrupted service or error-free results, and we are not liable for decisions you make on the basis of its estimates — including materials ordered, work quoted or costs incurred — or for losses arising from your use of it, to the extent the law allows.

Changes

We may update these terms. The date at the top of this page shows when they last changed, and continuing to use MyBuildTool after a change means you accept the updated terms. If a change materially affects what you pay or what you get, we will tell account holders by email.
