What Fuel Signal collects

Short version: the fuel surcharge calculator needs no account and we keep nothing you type into it. If you sign in, we hold your name and email address so the account is yours, and the load checks and trucks you save are kept against that account so you can see them again. We do not sell or share your information, and there are no advertising or analytics trackers anywhere on this site.

Using Fuel Signal is also covered by our terms, which say what the numbers are and are not.

Who runs this

Fuel Signal is operated by Logixtecs Solutions LLC. For anything about your information, or to have it deleted, email [email protected].

The calculator, with no account

The figures you type — a base price, a fuel economy — are sent to our own server, used to work out the surcharge, and returned to you. We do not store them and they are not attached to you or to anyone else. You can use the calculator without signing in, and we do not ask you to.

The diesel price itself comes from the U.S. Energy Information Administration’s weekly on-highway diesel series. That is public data about fuel, not data about you.

The load check is different, and the next section says so. This paragraph is about the surcharge calculator on the front page only.

If you sign in with Google

Signing in asks Google for three things and nothing more: your name, your email address, and the account identifier Google uses to tell us it is the same person next time. We use them to create your account and to show you who you are signed in as.

We do not ask for access to your Gmail, your files, your calendar or your contacts, and we cannot read them. We never see or store your Google password.

Fuel Signal’s use of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements. We use that information only to provide and improve the features you signed in for; we do not transfer it to others except as needed for those features, to comply with the law, or as part of a merger or sale; and we do not use it for advertising or allow humans to read it except with your permission, for security, or where the law requires it.

You can disconnect Fuel Signal at any time from your Google account permissions. Email us to have the account itself deleted.

The load check, when you are signed in

A load check is saved to your account, and that is the point of it — the rail beside the form is how you price the same lane again without typing it out. What we keep is the lane you typed and the places we matched it to, the rate, the miles, the costs used, the net we worked out and the diesel price on the day.

When you compare loads, the comparison saves each of its loads in exactly that way — one saved check per load that we could price — and it spends one check from your allowance for the whole comparison.

Anything you fill in about the run on a load check — its mileage, tank size, what is in the tank, the driver and overhead figures — is used to work out that answer and then kept only as part of that check.

Trucks you add on the Trucks page are kept against your account: the unit number, plate, VIN, miles per gallon and tank size you give us, so a check can start from them. A VIN is looked up in the U.S. government’s public vehicle database (NHTSA) to fill in the year, make and model. Saving trucks is on the paid plan, and you can remove one at any time on that page.

If your account already has trucks on it, we read them so you can price against one and so the form can start from its figures. You can email us to have the whole account and its history removed.

This information sits in our own database, run on Neon in the United States. It is scoped to your account at the database itself, not merely by our code.

Maps, routes and lane suggestions

The map on a load check is loaded from Google, in your browser. That means Google receives your network address and the fact that you opened a map, directly, and may set its own cookies to serve it. We do not control those and we do not read them. There is no map on any other page, and nothing about the map is used to build a profile of you by us.

To work out the miles and the tolls, the two ends of your lane are sent to Google’s routing service and to the mapping services that turn a town name into a position. If you say where your truck is now, that place is sent the same way, to work out the empty miles to the pickup; we keep the miles that come back, not where the truck was. If your account has exact addresses turned on, what you type into the lane boxes is also sent to Google as you type, so it can suggest real facilities and street addresses.

Fuel prices come from our own scrapes of public truck-stop pricing. Those are facts about pumps, not about you.

If you tell us what you would pay

When you run out of checks, or tap something that is on the paid plan, we ask what it would be worth to you. If you answer, we send your answer, which paid feature you asked about, the email address on your account, how many trucks you have, and anything you typed in the box to a Notion database we own, so we can read the replies and come back to you.

Answering is optional, it changes nothing about your account, and no card is involved — there is nothing to buy yet. That is the whole reason we are asking.

If you connect an AI app, such as Claude or ChatGPT

You can connect Fuel Signal to an AI app so it can check loads for you. You choose what connects: nothing is connected unless you press Allow on our page, which names the app and the address it will send you back to.

A connected app can run load checks and comparisons, and read your recent checks, your trucks, this week’s diesel price and the fuel surcharge. What it reads is sent to that app, under your account with that company, and their privacy policy governs what they keep. A check through the app is saved and counted exactly like one on this site. It cannot add or change a truck or your settings.

We keep a record of each connection — which app, when it was connected and last used — and a scrambled (hashed) copy of the token it uses to stay connected, never the token itself. You can disconnect an app at any time on your account page, and it stops working straight away.

Cookies — there are two, and neither follows you

fuel_session keeps you signed in for 30 days. It holds only your account reference, name and email address, it is signed so it cannot be altered, and it is readable only by our server.

fuel_oauth exists for up to ten minutes while you are signing in, to make sure the reply coming back from Google belongs to the sign-in you started. It is deleted the moment it is used.

That is the entire list of cookies we set. There are no advertising cookies, no analytics cookies, and no advertising or analytics trackers anywhere on this site.

⚠️ One honest exception, because it is not ours to promise away: the Google map on a load check is loaded from Google and may set cookies of its own, as described above. It appears on that page and nowhere else.

The newsletter

If you subscribe, your email address is passed to Freight Signal, our newsletter, which is run on Beehiiv and sends a weekly issue. Fuel Signal itself does not store or log the address — it hands it over and forgets it. Every issue has an unsubscribe link, and it is the only thing that address is used for.

We ask once, just after you sign in for the first time, and the answer is a button — nothing is sent and no address is passed on unless you press it. There is no pre-ticked box anywhere on this site, and saying no is not recorded or asked again.

Keeping the site working

Our server briefly counts requests by network address so that one script cannot take the calculator down for everyone. Those counts live in memory, expire within minutes and are not stored, not tied to your account, and not used to build any profile of you.

Fuel Signal is served through Cloudflare and runs on Railway, who handle traffic on our behalf and keep their own operational logs. Accounts, load checks and trucks are stored in a Neon database in the United States. Sign-in is Google; the newsletter is Beehiiv; the price question goes to Notion; a VIN you add is looked up with NHTSA, the U.S. vehicle-safety agency. Those are the only places we send any of this to, and each of them only the part described above. An AI app you choose to connect is the one addition, and only while you keep it connected — see the section above.

What we do not do

We do not sell your information, we do not share it with advertisers, we do not use it to train anything, and we do not track you across other websites. We do not ask for a card, and there is nothing on this site that charges you.

Changes

If the product starts touching something new, this page changes in the same release — not afterwards. The date at the top tells you when it was last revised.
