Effective Date & Governance Architecture
This cookie and storage ledger took effect on November 11, 2026 (2026-11-11). It provides a full technical accounting of every storage mechanism maintained by BT Garage LLC (138 Milford St, Upton, Massachusetts 01568, phone 508-762-1769) when you navigate btgaragellc.com.
Storage Categories in Active Operation
We classify browser storage into three precise categories to ensure technical necessity remains distinct from optional marketing measurements:
- Strictly Necessary Storage: Essential for foundational website operations, CSRF protection, anti-spam honeypot timing, and recording your affirmative consent preferences so you are not prompted repeatedly. These cannot be disabled while using the site.
- Functional Desk Storage: Enables conversational continuity in our workshop support chat by maintaining your unique session token in local browser storage, allowing Mechanic Alexey Ivanov to respond across page transitions.
- Attribution & Advertising Storage: Attaches click identifiers (such as Google Ads, Microsoft Advertising, and Meta Ads parameters) to verify which search campaign or mechanical repair keyword directed you to our Upton service bay.
Browser Storage and Cookie Ledger
The ledger below details each cookie and local storage key deployed on this website, specifying its originating controller, technical purpose, retention duration, and category:
| Storage Key | Domain / Origin | Category | Lifespan | Technical Purpose & Plain-English Meaning |
|---|---|---|---|---|
| site_consent_v2 | btgaragellc.com (localStorage) | Strictly Necessary | 12 Months |
Stores the visitor’s explicit cookie consent choice ("accept" or "decline") and timestamp. Governs whether advertising tags and telemetry scripts are activated.
|
| support_chat_token | btgaragellc.com (localStorage) | Functional | 6 Months |
Cryptographic session token issued by sebe2ba.php. Links subsequent messages to your ongoing conversation with our mechanic support desk without requiring a customer login.
|
| opened | btgaragellc.com (Session memory) | Strictly Necessary | Session only |

| _ga | .btgaragellc.com (1st party cookie) | Analytics | 14 Months | Distinguishes unique browsers to measure aggregate page visits, workshop inquiry completion rates, and average reading time across service descriptions. |
| _ga_* | .btgaragellc.com (1st party cookie) | Analytics | 14 Months | Maintains session state across individual page loads to determine if a visitor navigated from labor rates to diagnostic services before sending an estimate request. |
| _uetmsclkid | .btgaragellc.com (1st party cookie) | Advertising Attribution | 90 Days | Microsoft Advertising Universal Event Tracking (UET) cookie capturing Bing search ad click attribution to evaluate local search performance in Worcester County. |

Paid Advertising Platforms & Click Identifiers
BT Garage LLC runs active digital marketing campaigns on Google Ads, Microsoft Advertising, and Meta Ads to connect vehicle owners with our Upton repair facility. When a visitor selects one of our sponsored listings, the advertising platform appends a dedicated click identifier to the landing URL:
- Google Ads: Appends the
gclid(Google Click Identifier) query parameter. This allows our backend to confirm that a request for our 100 to 165 USD per hour mechanical repair rate originated from a specific search query. Must note google ads click attribution. - Microsoft Advertising: Appends the
msclkid(Microsoft Click Identifier) query parameter to trace referrals from Bing and partner networks under microsoft advertising. - Meta Ads: Appends the
fbclidquery parameter to verify referrals from social automotive service announcements.
These identifiers reside purely in URL query parameters and temporary attribution cookies. They do not give us access to your private profile on those networks. No statement on this website claims that Google Ads, Microsoft Advertising, or Meta Ads has reviewed, endorsed, or certified our garage.
Google Consent Mode v2 Operation
We implement Google Consent Mode v2 across every page of btgaragellc.com. By default under consent mode, prior to any visitor interaction with our consent dock, the following four consent signals are held strictly at denied:
These signals ensure that Google services do not write or read advertising cookies until you choose “Allow Storage”. If you select “Decline”, or if you later reset your preferences, all four signals immediately revert to denied, halting client-side tracking and ensuring cookieless measurement only.
How to Grant, Change, or Withdraw Storage Consent
Consent is requested on your initial page visit via the fixed bottom consent dock. You possess absolute freedom to choose:
- Granting Consent: Clicking “Allow Storage” sets
site_consent_v2to"accept"and updates Consent Mode v2 signals to granted. - Refusing Consent: Clicking “Decline” sets
site_consent_v2to"decline", keeping all non-essential storage blocked. - Changing Your Choice: You can modify or revoke your selection at any moment by clicking the control positioned in our site footer. Reopening the prompt allows you to switch your status instantly.
Operational Consequences of Refusing Storage
Declining optional cookies and storage keys does not hinder your ability to browse our website or engage our automotive repair workshop:
- What remains fully functional: You can review all service descriptions, examine labor rate benchmarks (100–165 USD/hr shop rate, 120 USD/hr median), read equipment ledgers, submit vehicle estimate inquiries via
gadu458.php, and telephone our garage directly at 508-762-1769. - What is adjusted: Advertising attribution scripts will not store persistent cross-session cookies on your computer, marketing campaigns cannot personalize subsequent ads to your device, and chat history may not persist if you close your browser tab.
Advertising Partner Privacy Governance
Our advertising partners maintain comprehensive documentation regarding their data storage, telemetry cookies, and consumer choices. We urge visitors to review their respective privacy policies directly:
- Google Ads & Analytics: Governed by Google’s Privacy & Terms portal at policies.google.com.
- Microsoft Advertising: Governed by the official Microsoft Privacy Statement available at privacy.microsoft.com.
- Meta Ads: Governed by the Meta Privacy Center at facebook.com/privacy/policy.
