Gemini Spark

Spark is a Google-hosted feature of the Gemini Apps; the only documented exports are per-skill .zip downloads and Google Takeout of account data. No documented route restores a working agent (tasks, schedules, skills, connections) on any runtime Google does not operate.

Skills can be downloaded individually as .zip and account data can be exported through Takeout, but no documentation shows schedules and triggers, remote-computer files, remote-browser state, past-chat memory or integration links leaving Google in usable form; Connected Apps and MCP links rely on Google Account linking.

Spark runs in Google's cloud ('Spark runs in the cloud instead of on your phone or computer') and requires a signed-in personal Google Account plus a Google AI Pro or Ultra subscription; cancelling the subscription removes access to Spark, tasks and schedules.

• Create & manage schedules for tasks in Gemini Spark

Spark runs only on Google's Gemini models; the documented model options (Gemini 3 Flash-Lite, Flash, Pro) are all Google-hosted, and no documentation shows third-party or local model support.

After subscription cancellation Spark data is retained but paused, and the Terms promise 'reasonable advance notice' and a Takeout opportunity when a service is discontinued, except in urgent situations. Download from a disabled account is 'may be able to', and accounts 'may be disabled without the ability to download data for certain violations'; no 30-day guarantee exists.

• Create & manage schedules for tasks in Gemini Spark

Agent state (tasks, schedules, remote-computer files, memory, provider instructions) is readable only through Google's Gemini apps and services. Skill files are plain-text SKILL.md, but the main state has no documented open format outside Google's service.

Google does not publish the base system prompt or provider-injected context that Spark runs with (shortfall 1), and the Spark pages do not document which Gemini model or version a task uses, while the limits page notes 'model names, versions, and availability may change' (shortfall 2). Owners see planned steps, progress, skills, apps and files used.

Google says it retains some data 'longer when necessary for legitimate business or legal purposes' with no stated bound, and some data 'until you delete your Google Account'. Human-reviewed chats are kept for up to 3 years, disconnected from the account and not visible item by item.

• Gemini Apps Privacy Hub
• How Google retains data we collect

Google says Gemini chats 'are not being used to show you ads. If this changes, we will clearly communicate it to you', which is a non-binding statement. Spark uses Google Search services (Flights, Hotels, Maps) and shows 'Trending' tasks and 'Recommended' skills; no documented paid or self-preferencing ranking was found, but the absence is not bound by terms.

The work panel shows steps and the files Gemini read or updated, and activity lives in Gemini Apps Activity. But Gemini Apps Activity auto-deletes after 18 months by default (pruned by default). Public docs also do not show that entries include arguments and recipients or that failed recording is surfaced (counted as not met under G12).

• Manage & delete your Gemini Apps activity

No documentation describes integrity data, hash chaining or an independent verifier for Spark's task history or Gemini Apps Activity. Google holds the record and it can be changed without trace from the owner's side.

• Find & manage your Gemini Spark tasks
• Gemini Apps Privacy Hub

No documented Spark tool edits Gemini Apps Activity or task threads, and skills cannot be deleted from a chat or task thread. But in the local Chrome browser Spark 'has access to all the same sites that you do, including sites you're signed into', and that path is limited only by model-applied 'site and action restrictions' (policy-level protection).

Spark's runtime, the Gemini apps and the Gemini models are closed and Google-hosted. No source is published for any required component.

The agent has no identity of its own. It acts as the owner's Google Account, with 'Sign in with Google', Google Account-linked Connected Apps and Password Manager logins, and Google can disable that account.

Skills and schedules can be edited and saved, but no documented version history, diff, attribution or rollback exists for skills, schedules, instructions, memory, tools or model changes.

• Customize Gemini's responses with your instructions

Owners can create, edit, replace and deactivate skills, edit schedule instructions and set 'Instructions for Gemini'. Google's base instructions and built-in behaviour cannot be replaced, and Google notes that owner instructions to avoid topics 'doesn't always work perfectly'.

Instructions for Gemini are itemised and editable. Past-chat memory can be managed only by deleting the source chats or correcting Gemini in conversation, and what Gemini has inferred is not itemised ('just ask Gemini'). Remote-computer files and remote-browser data can only be deleted as a whole.

Owners can add any MCP server as a custom app in the web app without Google review, and can disconnect Connected Apps. Some built-ins cannot be removed: Gemini 'can always use public information from Google Search', and no documented setting removes the remote browser or remote computer from Spark.

Provider protections such as 'prohibited task recognition', site and action restrictions, mandatory take-control for passwords and payments, required confirmation for custom-app write actions, and the no-network rule for skill scripts are set by Google. No documented control lets the owner change them.

Google changes Spark server-side through dated rollouts (new connected apps, monitoring behaviour, notifications). Model names and versions 'may change', Gems are being removed and auto-converted to skills, and no pinning or decline option is documented.

Limits are mostly on/off: per-app connections, per-device autobrowse and per-folder Mac access. No documented control limits whom the agent takes instructions from (content such as emails and websites can inject instructions), whom it contacts, or how much it spends; its web purchases can use saved Password Manager logins. Site scope is chosen by the model.

Confirmation prompts cover a fixed set of classes that Google defines, and Gemini is 'designed to ask' for them. Owners cannot choose which classes need approval, and Google Tasks bulk actions proceed without confirmation. Google also warns that offline schedules may complete unintended actions.

Per-task Stop and 'Turn off Gemini Spark' exist, and turning Spark off pauses all schedules and tasks until the owner turns it back on. No documented guarantee covers how fast in-flight provider-side work stops. Stopping a local-browser run may lead Gemini to continue via the remote browser, and after subscription cancellation 'in-progress Spark tasks will finish'. Per the C3 note this is Unverified.

Spark requires Keep Activity to be on, and with it on 'Google uses your activity to provide, develop, and improve its services (including training generative AI models)' with human reviewers. So content use for training and staff review is on by default and cannot be turned off while using Spark. Data-term changes follow Terms updates on notice, not specific consent.

Connected Apps and custom MCP servers are listed and can be disconnected or unlinked one by one. Remote-browser cookies holding website sign-ins are neither itemised nor revocable per site ('delete all saved browser data'), and Google says this data is used 'consistently with the Gemini Apps Privacy Notice', which does not limit use to owner-directed actions.

Deleting the agent takes several steps: task threads, schedules, skills, remote browser and remote computer data are deleted separately, and turning Spark off deletes remote data only. Human-reviewed chats 'are not deleted when you delete your activity' and are kept for up to 3 years. Google-wide deletion 'generally takes around 2 months', and backups can last up to 6 months.
