Privacy Policy
Overview
Hex Labs is an educational site with browser tools and learning resources for exploring ECU data, hexadecimal values and synthetic examples. This page describes the behavior present in the site code; it is not a statement that advertising is currently running.
Operator and contact
Hex Labs is operated by Adam Johnston as an individual based in Scotland, United Kingdom. For public enquiries and privacy requests, contact mail@adamj.link. This monitored email address opens your email application; the site's contact form is unavailable.
Data and browser storage
Tool calculations generally run in your browser. Some site and learning preferences, course progress, exercise state, and selected tool inputs or profiles are saved in this browser's local storage so a feature can restore them. What is stored depends on the feature; use its clear or reset control where provided, or clear this site's browser storage. A saved value is not sent to Hex Labs analytics merely because it is stored locally.
The VIN Decoder does not save the current VIN or lookup result. If you choose its NHTSA lookup, it sends the normalized VIN directly from your browser to NHTSA's vPIC service. Hex Labs does not proxy that request.
The site does not currently provide visitor accounts, payment features, or a working contact form.
Google Analytics
Google Analytics 4 is loaded only on https://hex-labs.pages.dev after you affirmatively allow analytics in Hex Labs privacy preferences and only when your browser's Do Not Track signal is not enabled. The preference is stored in local storage under hexlabsConsent:v1. The site sends page titles and paths, plus selected, fixed feature/action identifiers. It excludes tool inputs and outputs, VINs, filenames, share URLs, exercise answers and free text. Revoking the choice blocks subsequent Hex Labs analytics events without requiring a page reload.
Google provides this analytics service. See how Google uses information from sites or apps that use its services and Google's Privacy Policy.
External services
The optional VIN lookup contacts NHTSA vPIC directly only after you submit a valid VIN and choose to look it up. NHTSA receives the request; its service and privacy information apply to that request. The site does not send the VIN in its own analytics events.
Advertising and privacy choices
Hex Labs is preparing for a possible future AdSense review, but this site currently loads no advertising code and displays no ads. The owner reports that a Google European regulations message has been configured in AdSense. That account-side configuration is not connected to the current site build, so the message is not currently delivered by this site.
The Hex Labs privacy setting controls our optional Google Analytics only; it does not grant, refuse or reopen Google advertising consent. The Google message is configured with advertising consent mode enabled and analytics-purpose consent mode disabled, according to the owner's account setup. If advertising is introduced, the site will need the appropriate Google tag/message integration and updated disclosures before any ad requests. No ad personalization, cookie or data behavior is active through Hex Labs code now.
Use the browser storage notes and the Privacy preferences control in the footer to revisit Hex Labs analytics consent. A control for reopening Google's advertising message is not implemented in this build.
Changes and review status
This page should be updated when site behavior or vendors change. Data retention, transfers, and applicable legal wording should be reviewed against the actual operation.
