Privacy Policy

Last updated: July 2026

OBD Bay ("we," "us," "this site") is a free diagnostic reference tool. This policy explains what information is collected when you use the site, how it's used, and the choices available to you.

Information Stored in Your Browser

Your saved garage (vehicles you've added), theme (dark/light), and language preference are stored locally in your own browser using localStorage. This data:

• Never leaves your device or gets sent to us
• Is only accessible to you, on the device and browser you used to save it
• Can be cleared at any time by clearing your browser's site data, or by removing vehicles individually in the Garage section

Third-Party Services We Use

To look up vehicle details, OBD Bay sends VIN or year/make/model queries directly from your browser to the National Highway Traffic Safety Administration (NHTSA)'s free public vPIC API. This is a US government service; no account or personal information is required to use it. Read NHTSA's own privacy practices at nhtsa.gov.

Fonts are loaded from Google Fonts, which may log standard server request data (like your IP address) as part of serving the font files. See Google's Privacy Policy for details.

Advertising

This site may display ads served by Google AdSense. Google and its partners may use cookies and similar technologies to serve ads based on your visits to this and other websites, and to measure ad performance. You can learn more about how Google uses data and manage your ad personalization settings at Google's Ads Policy page and Google Ad Settings.

Affiliate Disclosure

OBD Bay participates in the Amazon Associates Program and may participate in similar affiliate programs with AutoZone, Advance Auto Parts, and NAPA. This means when you click certain part links and make a purchase, we may earn a small commission — at no extra cost to you. Affiliate relationships never influence which causes, parts, or diagnostic information we show for a given code.

What We Don't Do

• We don't require an account, login, or personal information to use this site
• We don't sell your data — we don't have any of your data to sell in the first place
• We don't track you across other websites

Contact Form / Email

If you email support@obdbay.org, we'll have whatever information you choose to include in that email (like your address if it's in your email signature). We use it only to respond to you, and don't share it with anyone else.

Children's Privacy

OBD Bay is not directed at children under 13, and we don't knowingly collect information from children under 13.

Changes to This Policy

If this policy changes, we'll update the "Last updated" date at the top of this page.
