Privacy Policy — Meineke Oil Sticker

Last updated: August 9, 2026

Meineke Oil Sticker ("the extension") is an internal tool built by ETF Auto for its own service writers and technicians. It is not offered to the general public and is distributed unlisted to ETF Auto staff. It runs only on the two systems ETF Auto shops already use: meineke.tekmetric.com (the shop management system) and tvpx.autovitals.com (the digital inspection system).

Nothing leaves the computer. The extension has no server, contacts no website, and sends no data over the internet. Its only outbound request goes to http://localhost:8080 — the shop's own label-printing program, running on that same PC.

What the extension does

After an oil change, someone has to write out a reminder sticker for the windshield. The extension reads the repair order already open on screen, shows the technician what it found, and — only after they confirm — sends it to the shop's label printer.

What data it handles

Only what is needed to print the sticker, read from the repair order already open in the user's own session:

The repair order number
Current odometer reading
Oil grade (for example 0W-20) and oil type (for example full synthetic)
The next-service mileage and date calculated from those

It does not read customer names, addresses, phone numbers, payment details or pricing.

Where that data goes

To the label-printing program on the same computer, over a local connection (localhost) that never leaves the machine. That program prints the sticker. No data is transmitted to ETF Auto, to the extension's developers, or to any third party. There is no analytics, no tracking, and no remote server of any kind.

What is stored

Nothing. The extension uses no browser storage, saves no files, and keeps no history. The sticker details exist only while the confirmation card is on screen, and are gone when it closes.

Why the permissions are needed

http://localhost:8080/ and http://127.0.0.1:8080/ — to reach the label-printing program on the same PC. A Chrome extension cannot talk to a printer directly; a small local program does that, and this is how the extension reaches it. These addresses always refer to the user's own computer.
Site access to meineke.tekmetric.com and tvpx.autovitals.com — to read the repair order on screen and to place the Print button and confirmation card on the page. The extension is inactive on every other website.

The extension requests no other permissions at all — no storage, no tabs, no downloads, no background access.

What the extension does not do

It does not sell or transfer data to third parties — it transmits no data off the machine at all.
It does not use data for any purpose other than printing that sticker.
It does not use data to determine creditworthiness or for lending purposes.
It does not track browsing, clicks, keystrokes or location.
It does not collect user credentials, and it downloads and runs no code from anywhere — every line it executes ships inside the extension package.
It never prints without a person confirming first, and when it cannot read enough from the repair order it says so rather than printing a guess.

Changes

If this policy changes, the updated version will be posted at this address with a new "last updated" date.
