Assessment: Google's help pages state what Spark confirms before doing, how to delete its remote browser and code data, and the risks of prompt injection. Spark has no public API, Google calls it experimental, and it runs only with Keep Activity on, the setting under which chats are used for model training and human review.

- Kind: Platform · vendor: Google LLC · category: Personal assistants · legal entity: Google LLC · provenance 54/100
- Auth: OAuth · pricing: Paid · x402: no · licence: Proprietary hosted service under the Google Terms of Service
- Probe metrics: not measured yet (probes haven't run)
- Status: Described by Google as an experimental feature in early development and as beta. Announced 19 May 2026 (https://support.google.com/gemini/answer/17094507; https://support.google.com/gemini/answer/13594961; https://gemini.google/us/release-notes/)
- Runs on: Google's cloud. Tasks continue with the user's devices off. Web browsing uses the user's local desktop Chrome or a remote browser, and code runs on a remote computer (https://support.google.com/gemini/answer/17094710; https://support.google.com/gemini/answer/17094507)
- Model: Google's own Gemini models. The limits page lists Gemini 3 Flash-Lite, Flash and Pro for Gemini Apps. Which model Spark uses is not stated, and no third-party model provider is named on the pages read (https://support.google.com/gemini/answer/16275805)
- Channels: Gemini mobile app, Gemini app on Mac and the web app at gemini.google.com. Tasks can also be started and checked in a Gemini Live chat. No text message or messaging app channel for Spark was found (https://support.google.com/gemini/answer/17094507; https://support.google.com/gemini/table/17434654)
- Acts without asking: Runs schedules on time, on matching Gmail messages and on topic events. Reads connected apps and browses. Bulk actions on private Google Tasks run without confirmation, per Google (https://support.google.com/gemini/answer/17094710; https://support.google.com/gemini/answer/17094507)
- Asks first: Sending communications, modifying data, making purchases, submitting web forms and Sign in with Google, per Google. Passwords and payment details are entered by the user in take control mode. Each browsing task asks for confirmation (https://support.google.com/gemini/answer/17094507)
- Approval controls: Connected apps are off by default and switched on one by one. A Stop button, a take control mode for the browser, pause and resume for schedules, and a switch that turns Spark off. No read-only setting for a connected app was found (https://gemini.google/us/overview/agent/spark/; https://support.google.com/gemini/answer/17094507; https://support.google.com/gemini/answer/17094710)
- Accounts: Gmail, Calendar, Drive, Docs, Sheets, Slides, Keep, Tasks, Contacts, Photos, YouTube, Search services and Maps, plus third-party connected apps and custom MCP servers. Websites the user is signed in to are reachable through the browser (https://support.google.com/gemini/answer/17094507; https://support.google.com/gemini/table/17434654; https://support.google.com/gemini/answer/17209137)
- Credential storage: The user signs in with a personal Google Account. Third-party and custom apps are linked to the Google Account and can be unlinked on its Linked apps page. Remote browser cookies with website sign-in details are saved in Google's cloud until deleted. Where connector tokens are held is not stated (https://support.google.com/gemini/answer/17209137; https://support.google.com/gemini/answer/17094507)
- Memory: Memory of past Gemini chats, saved instructions and skills. A remembered item is removed by deleting every chat that holds it, and by disconnecting the app it came from. Google says there may be a short delay (https://support.google.com/gemini/answer/16598469)
- Retention: Gemini Apps activity is deleted automatically after 18 months by default (3 months, 36 months or never by choice). Chats read by human reviewers are kept up to three years, disconnected from the account. Retention of remote browser and remote computer data is not given as a period (https://support.google.com/gemini/answer/13594961)
- Training: With Keep Activity on, activity is used to improve Google services, including training generative AI models, and a subset of chats is read by human reviewers. Spark needs Keep Activity on (https://support.google.com/gemini/answer/13594961; https://support.google.com/gemini/answer/17094507)
- Limits: 15 tasks running at once and 50 active schedules. Compute-based usage limits refresh every five hours up to a weekly limit. Pro has 4 times the standard limit, Ultra 5 or 20 times the Pro limit. The standard limit is not given as a number (https://support.google.com/gemini/answer/17094507; https://support.google.com/gemini/answer/17094710; https://support.google.com/gemini/answer/16275805)

## Before you call it

1. Do not plan an integration against Spark. No public API or MCP server was found, and a person must hold a Google AI Pro or Ultra subscription
2. Expect a confirmation request before sends, edits, purchases and web form submissions, and note that bulk changes to private Google Tasks run without one
3. Delete remote browser data and remote code execution data in Gemini Spark Settings after a sensitive session. Deleting a task thread or Gemini Apps activity does not remove them
4. Keep within 15 running tasks and 50 active schedules. A schedule does not run when 15 tasks are running or the usage limit is reached
5. Treat every safety statement here as Google's own description. None was tested, and no message was sent to the service
