This provision discloses that Google collects operational and tag deployment data from GTM users, but includes a specific limitation that this data will not be shared with other Google products without consent, which is a notable carve-out relative to typical cross-product data sharing terms.
Interpretive note: The provision does not specify what mechanism or form of consent is required before cross-product data sharing, creating ambiguity about how this limitation is operationally enforced.
The agreement establishes that Google collects data on GTM usage and tag deployment patterns, and commits that this specific dataset will not be shared across other Google products without the user's consent.

"We may collect information such as how the Service is used, and how and what tags are deployed. We may use this data to improve, maintain, protect and develop the Service as described in our privacy policy, but we will not share this data with any other Google product without Your consent.Excerpt from Google's Tag Manager Terms of Service
(1) REGULATORY LANDSCAPE: This provision engages GDPR Article 13 and 14 transparency obligations regarding the purposes and legal basis for Google's own data collection from GTM users. The stated purpose limitation to service improvement, maintenance, protection, and development is relevant to GDPR's purpose limitation principle under Article 5(1)(b). CCPA applies where the GTM account holder is a California business or individual. The referenced privacy policy governs the details of this collection and should be reviewed for the full scope of applicable data practices. (2) GOVERNANCE EXPOSURE: Medium. The consent-based limitation on cross-product data sharing is a meaningful disclosure, but the provision does not specify what constitutes consent for this purpose or how it is obtained. Compliance teams should determine whether the consent mechanism referenced is adequately documented and whether it meets GDPR or other applicable standards. (3) JURISDICTION FLAGS: EU/EEA deployments require that the legal basis for Google's collection of this operational data be clearly identified under GDPR. UK deployments engage UK GDPR. California deployments engage CCPA where the GTM user qualifies as a consumer under that statute. (4) CONTRACT AND VENDOR IMPLICATIONS: Organizations acting as data processors on behalf of clients should consider whether Google's collection of tag deployment data constitutes processing of data subject to their own controller obligations, and whether their data processing agreements with clients address this. (5) COMPLIANCE CONSIDERATIONS: Compliance teams should review the Google Privacy Policy as incorporated by reference to assess the full scope of data collection from GTM usage. The consent limitation on cross-product sharing should be confirmed to be operationally implemented and documented. Data mapping exercises should include GTM usage and tag deployment data as a category processed by Google.
