Terms of Use

Version 1.2 — last updated 31 October 2026. Terms of Use. These terms are an agreement between you and Chandima Himal Abeyesekera (“we”, “us”), an individual in Sri Lanka who publishes Nexora Engine under the brand name Arcline Studios, for Nexora Engine — the desktop app, the web version and this website. By creating an account or using the app you agree to them. If you do not agree, do not use the app.

Who we are

Nexora Engine is provided by Chandima Himal Abeyesekera, an individual in Sri Lanka who publishes it under the brand name Arcline Studios. Address: B1-06-11 Viyathpura Apartments, Weera Mawatha, Kalalgoda, Thalawathugoda, Sri Lanka. You can reach us at support@nexoraengine.xyz or through the in-app Contact page. Your account and the work you sync are held in our database at Supabase (region Northeast Asia (Tokyo), ap-northeast-1); our providers may store or process your data outside Sri Lanka.

Who can use it

Anyone may use Nexora Engine. If you are under 18, use it only with the agreement of a parent or guardian. You confirm the email address on your account is yours, and you keep your password to yourself: you are responsible for what happens under your account and for the documents you make.

Your work is yours

Everything you put in — company and bank details, terms, logos, seals, your customers’ details and the documents you save — stays yours. We store and sync it only to run the app for you. You are responsible for having the right to use everything you save, and for your own customers’ personal data that you put into a document.

Acceptable use

Use Nexora Engine for lawful business work. Do not break, overload or misuse the service, do not try to reach another person’s data, do not work around the usage limits or the bot check, and do not store material you have no right to store.

Plans and limits

The Free plan gives a limited number of tool uses per day (5 today), counted on our server and resetting at midnight Colombo time. Premium unlocks the full app and unlimited use; the Master ERP Engine and Templates are Premium features. There is no online checkout: you ask for Premium inside the app, we arrange payment with you directly, and the plan is switched on by hand. We may change the free limit and will say so in the app before it changes.

Payments and refunds

Payments for Premium are not refunded, except in two cases: (a) a special case, such as paying for the yearly plan when you meant the monthly one — ask us within 14 days and we will put it right; or (b) where the law gives you a right that cannot be removed. Premium can be revoked; if it is, the account goes back to the Free plan. Nothing in this section takes away a consumer right the law gives you.

Tools, not advice

The calculators and the documents (including the Import Tax calculator, pricing sheets, quotations and invoices) are tools and estimates. They are not tax, legal, accounting or financial advice, and nobody checks your documents for you. Check every figure and document yourself before you rely on it.

No warranty

The app is provided as it is. We work to keep it running and correct, but we do not promise that it will always be available, error-free or fit for a particular purpose.

Limitation of liability

As far as the law allows, we are not liable for lost profits, lost data or indirect losses that come from your use of the app. Nothing in these terms takes away a right the law gives you that cannot be waived.

Support and your data

The Contact page is how you reach us, including with any question about your data: the topics “Delete my account” and “Get a copy of my data” are shortcuts, and the Backup page exports a copy of your own records at any time. A conversation you open there belongs to your account. A guest conversation stays with this guest session and is NOT moved into an account — sign in first if you want it saved to your account. You can ask us to see your personal data, correct it, delete it (we delete the account and its records), or withdraw a consent you gave; we answer within 30 days.

How long we keep it

An account and the work in it live until you ask us to delete them. An unused guest account is removed after 30 days without activity. A closed support conversation and a decided Premium request are removed one year after they are closed. You can ask for a copy of everything, or for deletion, through the Contact page.

Desktop app

The desktop app checks for a newer version when it starts and again while it runs. If a newer version exists, you must update before you can continue using it.

Governing law

These terms are governed by the law of Sri Lanka.

Changes

We may update these terms; the version and date at the top change with them, and continuing to use the app means you accept the version you are reading. Any question goes through the in-app Contact page.
