"I wonder what our team is discussing with Gemini. Convenience is great, but is the history saved anywhere? If someone deletes it, is it gone without a trace?" Recently, we have received a steady stream of these questions from executives whose companies have begun using AI across the organization. They visibly feel the boost in productivity. On the other hand, if an employee planning to leave consults AI on confidential matters, or if a dispute with a client leads to a demand to produce past exchanges, where do those records live, who can delete them, and who can view them? With nobody able to answer, an uneasy ambiguity lingers.
Rather than a lack of control, the reality is closer to the fact that AI chats simply were not recognized as targets of governance. While email and document retention and audits are standard practices for the IT team, AI chats have been left outside that perimeter. This changed in June 2026. Two administrative controls were added to the Gemini app, and Google Vault rolled out support for retention rules and litigation holds covering the Gemini app. In short, the tools needed to bring AI interactions onto the same governance playing field as email and files are finally in place. In this article, we examine how SMB decision-makers can combine these tools to establish practical operational governance.
First, accurately understand who can delete Gemini history
Concerns almost always boil down to a single anxiety: fear that chat histories will be arbitrarily erased. Therefore, we should first establish exactly what changed in June 2026.
Two admin controls have been added to the Gemini app. The first is whether to allow users to access temporary chats. Temporary chats are disposable conversations not saved to history; when enabled, employees can conduct consultations without leaving a record. The other is whether to permit users to delete conversations. Administrators can decide whether users have the power to erase individual chats or their entire history. Both settings are on by default and can be turned off domain-wide, or by organizational unit (OU) or group, under Generative AI > Gemini app in the Admin console. Rollout of this feature began on June 16, 2026, reaching all Google Workspace customers by June 28.
What is crucial to recognize here is that simply turning off deletion is not an instant fix. Disabling deletion merely means that users cannot delete chats manually; the retention period for conversation history itself is governed separately by the conversation history settings in the Admin console. Options include 90 days, 540 days (approx. 18 months), 1,080 days (approx. 3 years), or do not auto-delete. If you stop deletion without addressing this setting, histories will still vanish once the configured retention window expires. Understanding that "preventing deletion" and "retaining data" are two distinct settings is the first key insight. For a comprehensive overview of the Admin console, see our Google Workspace Admin Console Guide as a reference map for setting locations.
Decide whether to permit or prohibit temporary chats based on business needs
The next dilemma is how to handle temporary chats. Defaulting to an outright ban across the board is not necessarily the right move.
Temporary chats have legitimate use cases. For example, HR and labor relations staff might brainstorm with AI to organize assumptions around sensitive personnel matters that cannot yet be publicized. Or an employee might temporarily paste text containing personal data to reformat it. There are genuine scenarios where not keeping a historical record is the cleaner, safer choice. Enforcing an across-the-board ban can backfire: employees may end up performing the same tasks in persistent chats, ironically leaving behind records of sensitive information that you wanted to protect.
On the flip side, leaving temporary chats open creates a loophole for anyone looking to conduct off-the-record consultations. The deciding factor is whether your organization holds an audit obligation regarding AI interactions. If your core business involves custom development, professional legal/accounting services, healthcare, or finance—where post-hoc accountability is paramount—it is safer to turn off temporary chats by default and lean toward keeping all interactions in history. Conversely, you can apply nuanced access by creating dedicated OUs for departments where confidential brainstorming is a routine necessity. Rather than adopting a blanket company-wide approach, you need to divide settings by OU based on operational needs. For governance principles extending into autonomous AI agents, see our overview in Gemini Spark Governance Design to understand how to draw these boundaries.
Introducing Vault ensures data persists even after deletion
The administrative controls discussed so far only dictate what users are permitted to do. Governance capable of withstanding audits and eDiscovery in the truest sense is realized only when you layer Google Vault on top.
In June 2026, Google Vault officially added support for retention rules and litigation holds covering the Gemini app across web and mobile. As a result, you can configure rules to retain Gemini conversations for a specific number of days or indefinitely across the entire domain or specific OUs, as well as apply litigation holds to designated OUs or user lists. What is decisive is the order of precedence: Vault retention rules and litigation holds always take precedence over Admin console settings, user deletion actions, and user activity controls. In other words, even if an employee manually deletes a chat, turns off activity history, or uses temporary chats, the chat data is preserved if a Vault retention rule is active, and reliably remains accessible to administrators whenever placed under a litigation hold.
This provides our first definitive answer to the opening worry of whether deleted chats can still be tracked. With Vault retention rules in place, user deletions are merely cosmetic on the client interface; organizational records persist. In fact, when an organization uses Vault for Gemini, employees opening a temporary chat are shown a notice explaining that their Gemini app activity may remain visible to Google Workspace domain administrators and Vault users for the duration specified by the domain's Gemini retention rules. The system is designed to make it transparent to employees that their activity remains governed, even when they think they are operating off the record.
There is one important caveat: this Vault support applies strictly to the standalone Gemini app (gemini.google.com and mobile apps) and does not cover Gemini in Workspace features like "Help me write" in Gmail or Google Docs. Because the latter are not retained in the exact same format, assuming that all AI interactions are captured by Vault creates a blind spot. You must draw a precise boundary around what is and is not covered by retention.
Unifying retention, deletion, and auditing into a single policy
Because the three mechanisms covered so far—temporary chat controls, history deletion controls, and Vault retention/litigation holds—can be configured independently, organizations often apply them piecemeal, leading to inconsistencies. To make them function as effective governance, you must unify them into a cohesive policy.
In summary, the logical sequence is as follows: first, decide how long your organization needs to preserve this data using Vault retention rules. This is your foundation. Next, determine how much leeway users should have with deletion and temporary chats via Gemini app controls. Finally, establish operational workflows to apply litigation holds when specific events arise, such as lawsuits, audits, or employee departures. Discrepancies—such as blocking deletions without defining retention periods, or banning deletions without implementing Vault under the assumption that data is preserved—present the greatest risk.
This unified approach connects directly to governance for other AI-generated data, such as AI meeting transcripts and Drive files. The core question of how to retain, classify, and audit AI-generated and AI-recorded data is also explored in AI Meeting Minutes Governance and AI Drive Classification and DLP. Rather than treating Gemini chat history in isolation, anchoring it within an overarching corporate policy on managing AI-touched data makes it much easier to maintain configuration consistency.
Case study: Bringing "vanished chats" under control at a 30-person design and production agency
Consider a real-world consultation from a design and production agency of about thirty employees (client name withheld). The catalyst was the discovery that a former employee had apparently consulted Gemini about handling confidential client blueprints while employed, but because the employee had deleted their history, what was discussed could not be traced. Although no actual damages occurred, the CEO turned pale at the thought of being unable to provide an accounting if litigation had arisen, and reached out to bring AI interactions under formal governance.
The company was on Google Workspace Business Standard. Checking their Gemini conversation history settings revealed that auto-deletion was still set to "off," while deletion and temporary chats remained turned on in their default state. We first upgraded them to a plan tier that included Vault licenses, then configured a Vault retention rule for the Gemini app to retain data company-wide for three years. Next, we turned off conversation deletion for operational design and production teams to keep histories intact, while granting temporary chat permissions via a dedicated OU for a handful of executive and administrative staff who routinely conduct confidential brainstorming. We also provided standard operating procedures for applying litigation holds to employees preparing to depart.
The technical setup itself took only half a day. The true value lay in the preceding step: sitting down with leadership to articulate which departments' conversations needed to be retained, for how long, and with priority over which user actions. A few months after implementation, when another client dispute prompted a request to produce past correspondence, the client contacted us to share that they successfully retrieved the relevant Gemini chats from Vault without issue. This case demonstrated the real-world value of ensuring data persists even after deletion.
Points to verify before evaluation
Before getting started at your own organization, verifying a few points will ensure sound decision-making. First, check whether your subscription tier supports Google Vault. Because Vault is included in higher-tier and Enterprise editions, confirming whether retention and litigation holds are supported on your current plan is the starting point. Next, check your current Gemini conversation history settings—specifically whether auto-deletion is configured, and whether deletion and temporary chats are enabled—by opening Generative AI in the Admin console. In most cases, these have been left untouched in their default state.
Most importantly, before diving into technical configurations, define the extent of your organization's audit obligations regarding AI interactions. If your operations center on work where retrospective accountability is required, retention and Vault are virtually indispensable; otherwise, excessive controls will merely degrade employee productivity. You cannot find this balance simply by looking at pricing charts or settings screens.
