By accessing or using FuelMath ("the Service"), you agree to be bound by these Terms of Use. FuelMath is operated by FuelMath, LLC, a California limited liability company ("FuelMath," "we," "us," or "our"). If you do not agree, do not use the Service. These terms apply to all users, including anonymous visitors, free account holders, and Pro subscribers.

You accept these terms by clicking "I agree" when you create an account; for paid plans, acceptance is captured again at checkout. We retain a timestamped record of your acceptance and of the version then in effect. These terms should be read alongside our Privacy Policy, which describes how we collect and use your information and is incorporated into these terms by reference.

FuelMath is a mileage and expense record-keeping application. It helps you log business trips and expenses, apply IRS standard mileage rates, and generate reports you can use when preparing tax returns or submitting reimbursement requests.

The term "IRS-ready" as used in our marketing means that FuelMath logs the fields required by IRS Publication 463 — date, starting point, destination, business purpose, and miles. It does not mean that any particular log entry or report is guaranteed to satisfy an IRS examination. Only reports you generate in IRS Deduction Mode (defined in Section 2a) are described as "IRS-ready."

FuelMath offers two separate calculation modes. They use different inputs, produce different outputs, and serve different purposes.

IRS Deduction Mode estimates a potential mileage deduction by multiplying the business miles you log by the IRS standard mileage rate then in effect in FuelMath. Its output is an estimate for tax record-keeping, and only reports generated in this mode are the reports we describe as "IRS-ready." As stated in Section 2, "IRS-ready" means only that the report captures the fields required by IRS Publication 463 — not that any deduction, entry, or report is guaranteed to be accepted in an IRS examination.

Fuel Cost Mode estimates the out-of-pocket cost of fuel for a drive using your logged miles, the price per gallon you enter, and a fuel-economy (MPG) figure for your vehicle. It is provided for personal and budgeting purposes only. Fuel Cost Mode does not apply the IRS standard mileage rate, does not calculate a tax deduction, and its outputs are not "IRS-ready" and should not be used to substantiate a tax deduction or a reimbursement claim.

Tax law is complex, changes frequently, and applies differently depending on your employment status, state of residence, business structure, and individual circumstances. A deduction that applies to one user may not apply to another. You should consult a qualified tax professional — such as a CPA, enrolled agent, or tax attorney — before making tax decisions based on FuelMath's output.

FuelMath expressly disclaims any liability arising from your reliance on information provided by the Service, including any penalties, interest, additional tax, or other consequences resulting from an audit, amended return, or IRS determination.

FuelMath estimates deductions based on information you enter. The accuracy of any output — mileage totals, deduction estimates, fuel cost figures, expense categories, or reports — depends entirely on the accuracy of the information you provide.

You are solely responsible for the accuracy of your tax filings and reimbursement claims. FuelMath is a tool to help you keep records — it does not file on your behalf and does not verify the tax accuracy of your entries.

FuelMath accounts are created via Google OAuth. You must have a valid Google account to use FuelMath. You are responsible for all activity that occurs under your account.

You may not share your account with others, create accounts on behalf of others without their consent, or use FuelMath to log trips or expenses for individuals other than yourself without their knowledge.

You must be at least 18 years old to create an account. By creating an account, you represent that you are 18 or older.

FuelMath Pro is available on an annual basis ($69/year) or monthly basis ($7.99/month). Pricing is subject to change. We will provide at least 30 days' email notice before any price increase takes effect on your active subscription. Continued use of the Service after a price change takes effect constitutes your acceptance of the new price.

You may cancel your Pro subscription at any time. Upon cancellation, you retain Pro access until the end of your current paid billing period. After that, your account reverts to the free tier.

Refund policy: We do not offer refunds for partial billing periods. If you cancel mid-year on an annual plan, you will retain Pro access through your renewal date but will not receive a prorated refund for the unused portion. Exceptions may be made at our sole discretion in cases of documented billing errors or extenuating circumstances — contact us at [email protected].

If a duplicate charge or billing error occurs, please contact us promptly. We will investigate and issue a refund if a billing error is confirmed.

You own the trip logs, expense entries, and other content you create in FuelMath. By using the Service, you grant FuelMath a limited license to store, display, and process your content solely for the purpose of providing the Service to you.

We do not claim ownership of your data and do not use your individual trip or expense records for any purpose other than operating the Service. See our Privacy Policy for full details.

Data portability: You can request a copy of your data at any time from your Account settings. If you are a free user, you may request a data export by contacting [email protected] — we will fulfill this request at no charge as required by applicable law. We strongly recommend exporting your records before requesting account deletion, as deleted data cannot be recovered.

You agree not to use FuelMath to:

Tax fraud: Using FuelMath to generate false mileage records for tax purposes is a violation of these terms and may constitute tax fraud under federal and state law. FuelMath reserves the right to terminate accounts found to be engaged in fraudulent activity and to cooperate with law enforcement as required.

FuelMath, including its design, code, content, and features, is owned by FuelMath and protected by copyright, trademark, and other intellectual property laws. These terms do not grant you any ownership interest in the Service.

You may not copy, modify, distribute, sell, or create derivative works from FuelMath's interface, code, or content without our written permission.

To the maximum extent permitted by applicable law, FuelMath, LLC and its members, managers, employees, contractors, and affiliates shall not be liable for any indirect, incidental, special, consequential, or punitive damages — including but not limited to:

In all cases, FuelMath, LLC's maximum total liability to you for any claim arising out of or relating to these terms or the Service shall not exceed the greater of (a) the amount you paid to FuelMath in the 12 months preceding the claim, or (b) $100 USD.

Nothing in this section limits or excludes liability that cannot be limited or excluded under applicable law, including liability for fraud, fraudulent misrepresentation, willful injury, gross negligence, or any violation of law that may not be limited under California Civil Code section 1668. Some jurisdictions do not allow the exclusion or limitation of certain damages; in such jurisdictions, our liability is limited to the greatest extent permitted by law.

FuelMath is provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.

We do not warrant that:

You agree to indemnify, defend, and hold harmless FuelMath, LLC and its members, managers, employees, and contractors from any claim, demand, loss, or expense — including reasonable legal fees — arising from (a) your willful misconduct or gross negligence in connection with the Service, (b) your violation of these terms or misuse of the Service, (c) your intentional infringement of any third-party intellectual property right, or (d) your submission of knowingly false information that causes direct harm to FuelMath, LLC. This indemnification obligation does not apply to claims arising from FuelMath's own negligence or wrongdoing.

You may delete your account at any time from account settings. Account deletion is permanent — we cannot restore deleted accounts or their data.

FuelMath reserves the right to suspend or terminate your account at any time, with or without notice, for violation of these terms, suspected fraudulent activity, extended inactivity, or at our discretion. In the event of termination for reasons other than terms violation, we will provide you with a reasonable opportunity to export your data before deletion.

If FuelMath discontinues the Service entirely, we will provide at least 30 days' notice to registered users and make data export available during that period.

Good faith resolution first: Before initiating arbitration, you agree to contact us at [email protected] and give us 90 days to attempt to resolve the dispute informally. We will do the same before initiating any claim against you. This 90-day period begins when written notice of the dispute is received.

These terms are governed by the laws of the State of California, United States, without regard to conflict of law principles. Any dispute arising out of or relating to these terms or the Service that cannot be resolved informally shall be submitted to binding arbitration under the Consumer Arbitration Rules of the American Arbitration Association, conducted in California. FuelMath will pay all AAA filing and arbitrator fees that exceed the cost of filing the same claim in court.

You waive any right to participate in a class action lawsuit or class-wide arbitration against FuelMath, LLC. Claims must be brought individually. This waiver does not bar a claim for public injunctive relief, which remains available in any forum (Cal. Civ. Code; McGill v. Citibank).

Nothing in this section limits your right to file a complaint with a regulatory authority, including the California Attorney General, the Federal Trade Commission, or any other applicable government agency.

You may opt out of this arbitration agreement by notifying us in writing at [email protected] within 30 days of first creating an account or first accepting these terms, whichever is later. Your opt-out notice must include your name, email address, and a clear statement that you wish to opt out of arbitration. Opting out does not affect your use of the Service or any other terms. Notwithstanding the above, either party may seek injunctive or other equitable relief in a court of competent jurisdiction to prevent irreparable harm pending arbitration.

If any provision of these Terms of Use is found to be unenforceable or invalid under applicable law, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will continue in full force and effect. The invalidity or unenforceability of any provision shall not affect the validity of any other provision.

We may update these terms from time to time. When we make material changes — those that affect your rights or obligations — we will notify you by email at least 14 days before the changes take effect. Material changes to the arbitration agreement or class-action waiver will not apply to disputes for which we have actual notice, and we will obtain renewed affirmative consent to such changes. Non-material updates (corrections, clarifications) may be made without notice, with the "Last updated" date reflecting the change.

Continued use of FuelMath after updated terms take effect constitutes your acceptance of the new terms. If you do not accept updated terms, you should delete your account before they take effect.
