Gemini

Incomplete, delayed and not restorable: Google Takeout exports Gems and activity asynchronously without memory, Connected Apps or credentials, and there is no import to restore them; Gemini's chat import accepts only ChatGPT and Claude exports.

• Import from other AI platforms to Gemini Apps

Takeout exports chats, generated media, uploads and Gems, but documentation does not state that memory derived from past chats, personal-context settings, Connected Apps configuration or credentials are included, so part of the agent stays with Google.

The Gemini app runtime and models are Google-hosted proprietary services; no open-source runtime can run the exported agent without Google servers.

• Download your Gemini Apps data

The agent's identity is the Google Account, which does not travel with an export, so nobody the agent has dealt with can verify its continuity after a move.

• Gemini Apps Privacy Hub

The functioning agent exists only on Google infrastructure and depends on the Google Account; exported files carry no license check but are not an executable agent.

Memory, Connected Apps, Gems and agent tasks are delivered by Google's platform and run only on Gemini models; none is documented to work with another provider or a local model.

• Use Gemini Spark / Agent for multi-step tasks

Takeout exports activity in readable formats (such as JSON or HTML in a .zip/.tgz archive), but live internal storage is undocumented and accessible only through Google's software.

• Download your Gemini Apps data

Owner instructions and Gem instructions are visible, but Google does not publish the Gemini app's system instructions or the personal context it injects from past chats and connected apps.

• Customize Gemini's responses with your instructions
• Memory of your past Gemini chats

Chats are retained 72 hours even with Keep Activity off, and chats selected for human review are retained up to three years even after the owner deletes activity.

• Gemini Apps Privacy Hub

Agent tasks show progress and a work panel of files accessed or modified, and chats are kept in Gemini Apps Activity and exportable via Takeout when Keep Activity is on. No complete record of actions and tool calls is documented, and history depends on activity settings.

Gems and instructions are plain natural-language text, but the app's agent logic and task orchestration are closed source.

• Customize Gemini's responses with your instructions

Google states there are no ads in the Gemini app and that Gemini chats are not used to show ads. Google has not made a binding commitment to keep the app ad-free and has described itself as open to ads, which already run in AI Overviews and AI Mode in Search.

Google does not document whether every consequential agent action is durably recorded, or whether an action is blocked when it cannot be recorded.

• Use Gemini Spark / Agent for multi-step tasks

Owner-visible history in Gemini Apps Activity can be deleted or auto-deleted without a detectable trace, and no tamper-evident record is documented.

• Gemini Apps Privacy Hub

Google does not document whether the agent layer can alter or delete records of its own actions.

• Use Gemini Spark / Agent for multi-step tasks

Takeout exports of Gemini Apps activity are readable with ordinary tools, but they are an activity export rather than a dedicated audit trail.

• Download your Gemini Apps data

The consumer app documents no agent-to-agent exchanges whose records each side could match against the other's.

• Use & manage Connected Apps in Gemini

The Gemini app and its service runtime are proprietary; no OSI-licensed, reproducible runtime is published.

• Gemini Apps Privacy Hub

The system instructions and injected personal context the app runs with are not published, so active configuration cannot be compared with inspectable configuration.

• Memory of your past Gemini chats

Messages go out through the owner's Google and connected accounts, so recipients cannot verify that they came from this agent, and no attribution survives leaving Google.

• Use & manage Connected Apps in Gemini

No action record is offered whose integrity can be checked with open tools that do not depend on Google.

• Download your Gemini Apps data

Server-side state is not fully exposed and Takeout is partial, so the owner cannot verify whether the agent's state changed between two points in time.

• Download your Gemini Apps data

Owners can view, edit and delete Instructions for Gemini and Gem instructions, but cannot read or rewrite the app's system instructions.

• Customize Gemini's responses with your instructions

Saved instructions are editable and past-chat memory can be switched off, but there is no viewer for individual derived memories; Google advises deleting the underlying chats or correcting Gemini in chat.

• Customize Gemini's responses with your instructions

Owners can create and edit Gems and Spark tasks/schedules, but cannot change the underlying agent logic or add executable code.

• Use Gemini Spark / Agent for multi-step tasks

Owners can enable or disable Connected Apps, and can add custom MCP servers for Gemini Spark. Custom apps require 18+, the US, a personal account, Keep Activity on and Spark access (Google AI Pro/Ultra).

• Connect & manage custom apps for Gemini Spark
• Use & manage Connected Apps in Gemini

Only Google's Gemini models can be selected in the app; third-party or local open-weight models are not supported.

• Use Gemini Spark / Agent for multi-step tasks

Adding custom tools requires a paid Google AI Pro/Ultra plan and eligible region, and depends on enabling Keep Activity.

• Use Gemini Spark / Agent for multi-step tasks

Owners choose which Connected Apps are enabled, and agent tasks ask before sending communications, but owners cannot set which recipients or channels the agent may contact, and no enforcement below the model is documented.

• Use & manage Connected Apps in Gemini
• Use Gemini Spark / Agent for multi-step tasks

Agent tasks prompt for confirmation before sending communications, modifying data, purchases and form submissions. The gated categories are set by Google, not selected by the owner, and enforcement cannot be independently verified.

• Use Gemini Spark / Agent for multi-step tasks

Owners can stop a task with Stop response or Take control of the browser, and can pause scheduled tasks from the work panel.

• Use Gemini Spark / Agent for multi-step tasks

All content is processed on Google servers by design. With Keep Activity on, Google uses chats to train its models and a subset is human-reviewed; this is opt-out rather than opt-in.

• Gemini Apps Privacy Hub

Connected Apps and custom MCP credentials are held by Google; owners can disconnect apps, but tokens are not inspectable and do not travel with an export.

Owners can delete Gemini Apps activity and Gems or their Google Account, but chats reviewed by humans are retained for up to three years, disconnected from the account.
