Terms of Service

Last updated: June 16, 2026

These Terms of Service (“Terms”) govern your use of fyrslf (the “Service”), operated by an individual based in Colorado, USA. By using the Service, you agree to these Terms. If you do not agree, please don’t use fyrslf.

Not financial advice

fyrslf is an educational and illustrative tool. It is not financial, investment, tax, legal, or accounting advice, and nothing it produces should be treated as a recommendation. Its projections are estimates generated from the assumptions you enter and from simplified models; real-world results will differ, and they may differ significantly. Markets, tax law, and your circumstances change. You are solely responsible for your financial decisions, and you should consult a qualified professional before acting on anything you see here.

Eligibility

You must be at least 18 years old to use fyrslf. By using the Service, you represent that you meet this requirement.

Your account

If you create an account, you are responsible for the activity under it and for keeping access to it secure. You agree to provide accurate information and to use the Service only for lawful purposes and in accordance with these Terms.

Acceptable use

You agree not to misuse the Service — for example, by attempting to disrupt or gain unauthorized access to it, reverse-engineering it beyond what the law allows, or using it to violate the rights of others.

No warranty

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that any calculation or result will be accurate or reliable.

Limitation of liability

To the fullest extent permitted by law, fyrslf and its operator will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, savings, data, or goodwill, arising out of or relating to your use of (or inability to use) the Service or any decisions made in reliance on it.

Changes to the Service and Terms

We may modify or discontinue the Service, and we may update these Terms, at any time. When we update the Terms, we’ll revise the “Last updated” date above. Your continued use of the Service after changes take effect means you accept the revised Terms.

Governing law

These Terms are governed by the laws of the State of Colorado, USA, without regard to its conflict-of-laws rules. Any disputes arising from these Terms or the Service will be subject to the exclusive jurisdiction of the state and federal courts located in Colorado.
