This Privacy Policy explains how the Chrome extension handles user data. More or less the same applies to the other apps.
Overview
Ceres is a browser assistant that helps users read, write, translate, summarize, speak, capture images, and work with selected browser content.
Ceres does not sell user data, does not use user data for advertising, and does not use user content to train our own AI models.
User content is sent outside the browser only when needed for a feature the user chooses to use, such as sending an AI request to the AI provider selected or configured by the user.
Data Ceres Handles
Depending on the features the user chooses to use, Ceres may handle:
- Prompts, chat messages, drafts, and assistant responses
- Selected text and selected HTML from web pages
- Active tab URL, page title, and page content when the user attaches or requests the current page
- Screenshots, cropped page areas, pasted images, and selected images
- Files, pasted content, or attachment content selected by the user
- Microphone audio when the user starts a voice feature
- Text extracted from images through OCR
- AI provider settings, API keys, provider endpoints, selected models, language preferences, and extension settings
- License key and license status when licensing is used
Ceres does not collect full browsing history for tracking, advertising, or profiling.
How Ceres Uses Data
Ceres uses data only to provide the feature requested by the user.
For example, selected text may be used for rewrite, grammar, summary, translation, explanation, or chat actions. A screenshot or image may be used for canvas editing, OCR, or an AI image request chosen by the user.
Ceres does not use user data for unrelated advertising, selling data, or building unrelated user profiles.
Browser Page Data
Ceres may access page data such as selected text, selected HTML, page URL, page title, visible tab screenshots, or current page content when the user uses a feature that needs that data.
This data is used to provide actions such as chat, rewrite, grammar correction, translation, summarization, explanation, screenshot capture, image editing, or inserting user-approved output back into the page.
Ceres follows the Chrome Web Store User Data Policy, including the Limited Use requirements.
AI Providers
Ceres can send AI requests to the provider selected or configured by the user.
An AI request may include prompts, selected text, page content, chat context, attached files, images, transcription text, model settings, and other content needed to complete the action requested by the user.
Supported provider types may include OpenAI-compatible providers, OpenRouter, Google-compatible providers, Anthropic-compatible providers, custom endpoints, and local providers.
External AI providers process data according to their own terms and privacy policies. Users should review the privacy policy of the provider they choose.
On-Device Browser AI
Some Ceres features can use browser-provided on-device AI, such as writing, translation, summarization, or language features when available in the user's browser.
When a feature runs through browser-provided on-device AI, processing is handled by the browser environment. The browser may download local AI model files needed for that feature.
When the user chooses a remote AI provider instead, the request is sent to that selected provider.
Voice And Microphone
Ceres uses the microphone only when the user starts a voice or dictation feature and grants microphone permission.
Voice input may be handled by browser-provided speech recognition or by an audio-capable AI transcription model selected by the user.
If browser speech recognition is used, speech processing is handled by the browser or platform provider. If an AI transcription model is selected, the audio needed for transcription is sent to the selected AI provider.
Ceres does not store permanent voice recordings on our server.
OCR
Ceres can extract text from images using OCR.
OCR is processed locally in the browser. Images used only for OCR are not sent to an AI provider or to our server for OCR processing.
If the user separately chooses an AI chat or image feature with an image, that image may be sent to the AI provider selected or configured by the user.
Screenshots, Images, And Canvas
Ceres can capture the visible tab, crop selected page areas, accept pasted images, and provide image or canvas editing features.
Images and screenshots may be stored locally in browser storage while the user works with them.
Images or screenshots are sent to an external AI provider only when the user chooses an AI feature that requires sending that image.
File Attachments
Ceres allows users to attach or paste files, including images, text files, code files, structured text files, and PDFs.
Attached content may be read locally so it can be added to the user's prompt or chat context.
Attached content is sent to an AI provider only when the user sends an AI request that includes that attachment or its extracted content.
Local Folder Access
Ceres may ask the user to select which local folder they want to give access to through the browser File System Access API when the user chooses a feature that needs local file access.
Folder access is optional. When the user grants access, Ceres may scan file names, folder structure, file metadata, and selected file contents locally in the browser to help find relevant information or prepare context for the user.
Local folder contents are not automatically sent to an AI provider or to any external service. Files or extracted file content are sent to the user's selected AI provider only when the user chooses to include them in a chat, prompt, or AI request.
Ceres may write generated or edited files inside the folder selected by the user when the user uses a feature that saves files locally.
Folder access information, such as the selected folder name and permission state, may be stored locally in browser storage.
Storage And Chrome Sync
Ceres stores settings and working data using browser-provided storage such as Chrome Storage Local, Chrome Storage Sync, and browser local storage.
Stored data may include API keys, provider endpoints, selected models, language settings, custom prompts, chat history, drafts, attached content, images, license state, and extension preferences.
Some settings and credentials may be stored in Chrome Storage Sync. If Chrome Sync is enabled in the user's browser, Chrome may sync those values between the user's Chrome browser installations. Chrome Sync is provided by Chrome, not by us.
Ceres does not operate its own sync server for Chrome extension conversations, prompts, page content, API keys, files, images, or voice recordings.
OpenRouter Connection
Ceres can help users connect an OpenRouter account through a browser-based connection flow.
When the user connects OpenRouter, Ceres stores the provider settings needed to use that account.
OpenRouter processes requests according to OpenRouter's own terms and privacy policy.
License Verification
If the user enters a license key, Ceres stores the license key and license status in browser storage.
For Gumroad licenses, Ceres may send the license key to Gumroad to verify the license. Gumroad processes that request according to its own terms and privacy policy.
Version And Notice Checks
Ceres may contact ceres-assistant.com to check version information, update notices, or product messages but not auto update any source code.
These checks are used to show extension-related notices and do not send prompts, selected text, page content, files, images, or voice recordings.
Data Sharing
Ceres shares data only when needed for a feature the user chooses to use.
This may include:
- Sending AI requests to the AI provider selected or configured by the user
- Sending audio to the selected AI provider when the user uses an AI transcription model
- Sending a license key to Gumroad when the user verifies a Gumroad license
- Checking ceres-assistant.com for version information or notices
We do not sell user data. We do not share user data with advertisers. We do not use user conversations, prompts, page content, selected text, images, files, or voice data to train our own AI models.
Analytics
Ceres does not include an in-extension analytics system for tracking user activity inside the extension.
Chrome Web Store may provide marketplace-level statistics, such as install counts or store dashboard metrics, according to Google's own policies.
Our public website may use website analytics for site traffic. Website analytics are separate from the Ceres Chrome extension.
Data Retention
Locally stored extension data remains in the user's browser storage until the user removes it, clears browser storage, changes settings, or uninstalls the extension.
Data sent to an AI provider is handled according to that provider's retention policy.
License verification data sent to Gumroad is handled according to Gumroad's retention policy.
Data Deletion
Users can delete locally stored Ceres data by:
- Removing saved API keys, provider settings, custom prompts, and license keys inside Ceres
- Clearing Chrome extension storage or browser local storage
- Turning off Chrome Sync for extension settings if they do not want synced settings
- Uninstalling the Ceres Chrome extension
For data already sent to an external AI provider or Gumroad, users should contact that provider or use that provider's account tools.
Security
Ceres uses the permission and storage systems provided by Chrome and the user's browser environment.
Users should protect their browser profile, device, API keys, provider accounts, and license keys.
The security and retention practices of external providers depend on the provider selected or configured by the user.
Children
Ceres is not directed to children.
Users who are not old enough to use browser extensions or AI providers under the laws of their country should not use Ceres without permission from a parent or guardian.
Changes To This Policy
We may update this Privacy Policy when Ceres, its features, or provider integrations change.
The updated version will include a new last updated date.
