Terms of Use

Last updated: 8 October 2026

Using this site

These terms apply to the crypto calculators on this site, which is run by Lumara (“we”, “us”). By using the site you agree to them. If you do not agree, please do not use the site.

What the site offers

The site offers free calculators, converters and short explanations about crypto tax, profit, fees and trading. They are for education and general information.

Not advice

Nothing on this site is tax, legal, financial or investment advice, and using it does not make you our client. Speak to a qualified professional before you act on a result. The Disclaimer says more about this.

Accuracy

We try to keep the rates, rules and formulas up to date, but tax law and exchange rules change and may differ from what is shown here. Results are estimates that depend on the figures you enter. We do not promise that the site is complete, current or free of errors.

Acceptable use

You may use the calculators for your own personal or business calculations. Please do not:

• try to disrupt the site or get into the systems behind it;
• use the site in a way that breaks the law;
• copy or republish the site, or a large part of it, as your own without our permission.

Ownership

The lumara name and the design, text and code of this site belong to Lumara or are used with permission. The site also uses open-source software and fonts, which stay under their own licences.

Links to other sites

The site links to other websites, such as official tax pages. We do not control them and are not responsible for what they contain.

Availability

The site is provided as it is. We may change, pause or remove any part of it at any time without notice.

Liability

To the fullest extent the law allows, Lumara is not liable for any loss or damage that comes from using the site or relying on its results, including tax owed, penalties, trading losses or lost profit. Nothing in these terms limits any rights you have that cannot be limited by law.

Privacy

The Privacy Policy and the Cookie Policy explain how the site handles information.

Changes to these terms

We may update these terms. The date at the top shows the latest version, and using the site after a change means you accept it.
