Terms of Service
Effective May 12, 2026.
These terms (the “Terms”) govern your use of OpenFuel, a crowdsourced map of gas and alternative-fuel stations and their prices, available at openfuel.app (the “Service”). The Service is operated by Anthony Zachman, a sole proprietor based in California, doing business as “OpenFuel” (“OpenFuel,” “we,” “us”).
Please read these Terms carefully. By creating an account, signing in, or otherwise using the Service, you agree to be bound by them.
1. Eligibility
You must be at least 18 years old to use the Service. By using OpenFuel you represent that you are 18 or older and that you have the legal capacity to enter into a binding contract. The Service is not directed at children. If we learn that we have collected information from someone under 18 we will delete it.
2. Your account
•
You are responsible for everything that happens under your account, including the security of your password.
•
You agree to provide an accurate email address and to keep it current.
•
You agree not to create more than one account, not to share your account, and not to impersonate another person.
•
You may delete your account at any time from the in-app settings page. See the Privacy Policy for what happens to your data on deletion.
3. The crowdsourced data — accuracy disclaimer
Prices on OpenFuel are submitted by other users. They are a best-effort, community-maintained snapshot. They are not a price guarantee from any station, fuel retailer, or fuel producer.
•
Always verify the price posted on the pump or the pole sign before you fuel up. The price you actually pay is the price the station charges, not the price OpenFuel shows.
•
Always verify the fuel type at the pump before you dispense. Putting the wrong fuel in your vehicle can damage it. Renewable diesel (R99), biodiesel blends, ethanol blends, and conventional fuels look similar but are not interchangeable in every vehicle.
•
Station hours, station closures, station ownership changes, fuel availability, octane levels, and seasonal blends can change without warning. We have no relationship with the stations shown on the map.
•
OpenFuel does not pump, sell, blend, transport, certify, or warrant any fuel.
4. User content and license
When you submit a price, confirm a price, file a fuel-not-sold report, file a missing-station report, upload a photo, or post any other content to the Service (collectively, “User Content”), you keep ownership of it. You also grant OpenFuel and the public the following licenses:
•
You grant OpenFuel a worldwide, perpetual, irrevocable, royalty-free, sublicensable license to host, store, reproduce, modify (for example, to compress an avatar to thumbnail size), display, transmit, and use your User Content for the purpose of operating, improving, and promoting the Service, and to comply with the law.
•
For User Content that the Service publishes openly — most importantly the price, fuel type, posted-as designation, station, and timestamp of every submission, plus your display name as it appears at the time of submission — you also grant the public the same broad license. This is the point of a crowdsourced public price database.
•
For photos uploaded through the in-app submit flow, your license is limited to operating the Service. The photo is processed for optical character recognition and then deleted from our storage once the submission completes successfully. We do not redistribute submission photos.
You represent and warrant that you have the right to grant these licenses, and that your User Content does not infringe anyone else’s rights.
Submitted prices are append-only. By design, our database does not allow a posted price to be edited or deleted — only marked outdated by a more recent submission. If you submit an incorrect price, the way to correct it is to submit a new, correct price. If you delete your account, the price record itself remains (anonymized) so the public price history of the station is not corrupted; only your association with it is removed.
5. Acceptable use
You agree not to:
•
Submit a price you did not personally observe at the pump or pole sign of the station you are submitting against, within the last several hours.
•
Submit a price for a station you are not physically present at. The Service enforces a server-side geofence of approximately 500 yards on every submission and confirmation, but you also agree not to spoof, fake, or otherwise misrepresent your location.
•
Submit photos that contain people, license plates, payment information, or any other identifying or sensitive information of any third party.
•
Submit content that is unlawful, fraudulent, defamatory, obscene, harassing, hateful, or that infringes any third party's rights.
•
Use the Service to harass, threaten, dox, or impersonate any person.
•
Operate more than one account, or operate an account on behalf of a station owner without disclosing that you are doing so.
•
Game the trust score, leaderboard, or coverage map by coordinated submissions, multi-accounting, or any other manipulation.
•
Probe, scan, or attempt to disrupt the Service, the underlying database, or the rate-limit and anti-abuse systems.
•
Scrape, crawl, or bulk-download the Service in a manner that would degrade it for other users. If you want a research-scale extract of the public price database, contact us first.
•
Reverse engineer, decompile, or attempt to extract the source code of any part of the Service that we have not made public.
•
Use the Service in violation of any applicable law or regulation.
6. Third-party data and attribution
The map shown in the Service combines our crowdsourced submissions with public datasets:
•
Station locations and tags are sourced in part from OpenStreetMap contributors and are made available to you under the Open Database License (ODbL). You can read the license at opendatacommons.org/licenses/odbl. The required "© OpenStreetMap contributors" attribution is shown on the map.
•
Alternative-fuel station information is sourced in part from the U.S. Department of Energy Alternative Fuels Data Center (AFDC), which publishes its data in the public domain. We display an AFDC credit in the footer.
•
Map tiles are served by Mapbox under their own terms; their attribution control is shown on the map.
Your use of any data sourced from these third parties through the Service is also subject to the upstream license. Most importantly: if you redistribute OpenStreetMap-derived data, you must comply with the ODbL, including its share-alike and attribution requirements.
7. Our intellectual property
Subject to your rights in your own User Content, the Service, the OpenFuel name and logo, the source code, the user interface, the trust and territory mechanics, and the documentation are the intellectual property of OpenFuel and its licensors. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for personal, non-commercial purposes in accordance with these Terms. Nothing in these Terms grants you any other license or right.
8. Reporting abuse and copyright concerns
If you believe a piece of User Content infringes your copyright, misrepresents you, or otherwise violates these Terms, send a notice to support@openfuel.app with:
•
A description of the content and its location on the Service (a station name, a station id, or a direct URL).
•
A description of why you believe it is infringing or violating.
•
Your name, your relationship to the work or person at issue, and a way to contact you.
•
For copyright claims, a statement made under penalty of perjury that the information is accurate and that you are the copyright owner or are authorized to act on the owner's behalf.
We will review every notice and take appropriate action in our reasonable discretion, which may include removing or anonymizing content, restricting access to the account that posted it, or referring the matter to law enforcement.
9. Termination
You may stop using the Service at any time and may delete your account from in-app settings.
We may suspend or terminate your access to the Service, with or without notice, if we reasonably believe you have violated these Terms, if your activity poses a risk to the Service or other users, or if we are required to do so by law. Where reasonable and lawful we will tell you why.
Sections of these Terms that by their nature should survive termination — including User Content licenses for previously published content, disclaimers, indemnification, limitation of liability, and dispute resolution — will survive.
10. Disclaimer of warranties
The Service is provided “as is” and “as available,” without warranty of any kind. To the fullest extent permitted by law, OpenFuel disclaims all warranties, express or implied, including the implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, secure, or free of harmful components, or that any data shown — including station locations, fuel types, station hours, prices, or any educational content — is accurate, complete, or current.
11. Limitation of liability
To the fullest extent permitted by law, OpenFuel and its operator, contributors, and vendors will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, fuel, vehicle damage, time, goodwill, or other intangible losses, arising out of or related to your use of (or inability to use) the Service, even if we have been advised of the possibility of such damages.
Our total cumulative liability to you for all claims arising out of or related to the Service is limited to the greater of: (a) the amounts you have paid OpenFuel in the twelve months preceding the event giving rise to the claim, or (b) one hundred U.S. dollars (US $100). Because OpenFuel is currently free to use, the practical effect of this clause is the second cap.
Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of these limitations may not apply to you.
12. Indemnification
You agree to defend, indemnify, and hold harmless OpenFuel and its operator from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising out of or in any way connected with (a) your User Content, (b) your use of the Service, (c) your violation of these Terms, or (d) your violation of any third-party right, including any intellectual-property or privacy right.
13. Governing law and venue
These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws principles. The exclusive venue for any dispute arising out of or related to these Terms or the Service is the state and federal courts located in San Diego County, California, and you and OpenFuel each consent to the personal jurisdiction of those courts.
14. Dispute resolution
Before filing any claim against OpenFuel, you agree to first contact us at support@openfuel.app and try in good faith to resolve the dispute informally for at least sixty days.
Any claim that is not resolved informally must be brought individually. You agree that you will not bring a claim against OpenFuel as a plaintiff or class member in a class, collective, or representative action.
15. Changes to the Service and to these Terms
We may change, suspend, or discontinue any part of the Service at any time. We may also update these Terms from time to time. When we do, we will update the effective date at the top of this page, and for material changes we will display an in-app notice on the map screen for at least thirty days. Your continued use of the Service after a change takes effect means you accept the revised Terms. If you do not accept them, you must stop using the Service.
16. Miscellaneous
•
Entire agreement: these Terms, together with the Privacy Policy, are the entire agreement between you and OpenFuel regarding the Service, and supersede any prior agreements.
•
Severability: if any part of these Terms is held to be unenforceable, the rest remains in effect.
•
No waiver: our failure to enforce any provision is not a waiver of that provision.
•
Assignment: you may not assign these Terms without our prior written consent. We may assign them in connection with a merger, sale, or other transfer.
•
No third-party beneficiaries: nothing in these Terms creates rights in any party other than you and OpenFuel.
•
Headings: section headings are for convenience only and do not affect interpretation.
