ConsentLine

A consent management platform engineered by Interface that blocks GTM and analytics scripts from entering the document until a visitor grants permission. Zero requests to Google before consent—verified with network captures on every deployed site.

What this is

Most consent management platforms rely on Google Consent Mode, which allows tags to fire "cookieless" pings before a visitor has agreed to anything. ConsentLine takes a different approach: it gates the document itself. No analytics or marketing script enters the page until consent is granted. Interface built the platform after observing real cases of analytics firing before consent under conventional CMP setups—including on our own site. That observation drove the architecture: block by default, verify by network capture, and treat compliance as an operated service rather than a one-time install. ConsentLine runs in production across Interface-operated client sites and on ifmm.com and consentline.com—the platform runs its own CMP.

How it works

The hard-block difference

Most CMPs operate by configuration: they instruct tags to suppress certain data when consent is absent. ConsentLine operates by exclusion: GTM and analytics scripts do not enter the document until the visitor grants permission. There is no configuration to misconfigure, no cookieless ping that slips through. Every deployed site is verified by network capture—the panel shows zero requests to Google before consent is given.

Jurisdiction-aware compliance and Global Privacy Control

ConsentLine geo-detects each visitor at the edge and applies the correct ruleset across eight US state privacy laws—CPRA, VCDPA, CPA, CTDPA, DPDPA, TDPSA, OCPA, and NJDPA—plus a US baseline. When location cannot be determined, the platform fails closed to the most conservative posture rather than defaulting to permissive behavior. Global Privacy Control browser signals are honored on first visit and re-applied for returning visitors.

Evidence log and 24/7 monitoring

Every consent choice is recorded to an append-only log with salted IP hashes—no raw PII is stored. The log is exportable as CSV for audits and data-subject requests, and archived daily with integrity verification. An independent monitor checks every deployed site around the clock for configuration drift and uptime, alerting the team on first failure. Compliance is treated as an operated service: the platform does not assume a correct install stays correct.

Hosted policies, portal, and real-estate document options

Privacy policy, terms, and cookie policy are authored from original counsel-reviewed templates—written from scratch, not derived from any vendor's documents—and hosted centrally. A client portal allows edits, but every change is human-reviewed before it goes live and recorded in permanent revision history. Embeds are paste-once: when a policy updates centrally, every embed on every site updates with it. For real estate clients, optional document sections cover fair housing, accessibility statements, DMCA, and property-marketing disclosures.

Why it matters

US state privacy laws carry real litigation risk, and most CMPs quietly leak—tags fire before consent in ways the configuration never flags. Interface built ConsentLine after confirming this pattern in production on our own properties. The platform blocks by default, monitors continuously, and keeps its compliance evidence in an auditable log. That is the same operational discipline Interface applies to infrastructure—not a point-in-time install that drifts silently after launch.

Common questions

About ConsentLine

How is ConsentLine different from a typical consent management platform?

expand_more
Most CMPs use Google Consent Mode, which lets tags fire "cookieless" pings before a visitor consents. ConsentLine blocks GTM and analytics scripts from entering the document entirely until permission is granted—there is nothing to configure correctly after the fact. Every deployment is verified by network capture to confirm zero pre-consent requests.

What visitor data does ConsentLine store?

expand_more
Consent choices are recorded with salted IP hashes—no raw IP addresses or other personally identifiable information are written to the log. The record contains the timestamp, the choices made, the applicable jurisdiction ruleset, and a hash sufficient to associate the record with a device for data-subject requests without storing the raw identifier.

Does it work with Google Tag Manager and GA4?

expand_more
Yes—that is the point. GTM and GA4 are gated at the document level: they do not load until the visitor grants Analytics consent. Once consent is given, tag firing proceeds normally. The platform does not require removing or replacing your existing GTM setup.

Can Interface deploy ConsentLine for our site?

expand_more
Yes. The platform was built to operate across multiple sites with per-site configuration—jurisdiction rules, consent purposes, policy embeds, and monitoring all scoped to each deployment. Start the conversation and we will scope it to your stack.

What happens if a visitor's location cannot be determined?

expand_more
ConsentLine fails closed. When the edge cannot resolve a visitor's jurisdiction, it applies the most conservative consent posture in the ruleset rather than defaulting to a permissive baseline. The platform does not assume a visitor is exempt from privacy rules because their location is ambiguous.
