Plain-language answers about cookies and browser storage.
A straightforward explanation of the browser cookies, local storage keys, and marketing tags deployed on trenvios.com. Written in plain questions with exact technical disclosures.
When did this cookie notice take effect?
This notice took effect on October 16, 2026. It reflects our current tracking setup, advertising integration rules, and Consent Mode v2 implementation across trenvios.com.
What categories of cookies and storage do you use?
Trenvios divides browser storage and cookies into three operational categories:
-
•
Strictly Necessary Storage: Local storage keys that preserve your privacy consent choice and keep the support chat session token active so you can converse with dispatchers across page reloads. These cannot be disabled because the site cannot function securely without them.
-
•
Measurement & Analytics: Aggregated diagnostic metrics that measure which dispatch service pages receive visitors, how long readers spend evaluating rate tables, and whether form validation errors occur.
-
•
Advertising & Conversion Attribution: Parameters that connect an inquiry back to the paid advertising click that brought the visitor to our website, allowing us to evaluate marketing efficiency without purchasing third-party broker profiles.

The complete inventory of cookies and local storage items utilized on this website is detailed in the table below:
| Key / Cookie Name | Origin / Provider | Operational Purpose | Storage Duration |

Which advertising platforms track visits, and what identifiers do they use?
Our dispatch desk purchases search and display advertising to reach businesses and individuals needing Chicago courier runs. Active traffic arrives from google ads, Microsoft Advertising (microsoft advertising), and Meta Ads.
These platforms attach unique alphanumeric click identifiers to landing page links:
- Google Ads attaches
gclid(Google Click Identifier) on google ads traffic. - Microsoft Advertising attaches
msclkid(Microsoft Click Identifier) on microsoft advertising traffic. - Meta Ads attaches
fbclid(Facebook Click Identifier).
Our client-side scripts read these parameters to credit the originating campaign when an inquiry form is sent to our dispatch desk.
How does Google Consent Mode v2 work on this website?
We have deployed Google consent mode v2 across the entire website. By default, before you take any action on our banner, the four technical permission signals are initialized in an explicit denied state:
ad_storage: deniedad_user_data: deniedad_personalization: deniedanalytics_storage: denied
These signals instruct Google scripts and partner conversion tags to refrain from reading or writing advertising cookies. Only if you click "Accept Storage" do these signals update to granted. If you click "Decline" or adjust your choice later, all four are returned to denied.
How do I make my consent choice, and how can I change it later?
When you first arrive on trenvios.com, a compact banner docks at the bottom of the viewport offering two clear buttons: "Accept Storage" and "Decline".
Your choice is instantly recorded in your browser under the key site_consent_v2. You are never locked into this decision. You can reopen the consent interface at any time by using the Cookie Settings button located in the footer of every single page on this website. Clicking it reopens the selection bar so you can update your preference with one tap.
What happens if I decline cookies and storage?
If you choose to decline, the core functionality of the website remains completely open and unimpeded. You can browse all dispatch services, review small parcel pricing (17–45 USD), check pallet freight options (25–150 USD), read postal forwarding schedules, and submit courier intake manifests through our forms without restriction.
The only mechanisms halted are marketing cookies, advertising attribution pixels, and third-party tracking scripts. The consent mode signals remain denied, so no conversion profile is created for your visit.
Where can I read the privacy policies of the advertising platforms?
Each advertising platform provides its own documentation regarding how click identifiers, remarketing lists, and attribution signals are processed under their enterprise policies:
- Google advertising and privacy practices: policies.google.com
- Microsoft Advertising statement: privacy.microsoft.com
- Meta Platforms data policy: facebook.com/privacy/policy
We recommend reviewing these policies to understand cross-platform data handling beyond our Michigan Avenue dispatch operations.
