Such Summary — Privacy policy
Last updated: 14 June 2026
Overview
Such Summary is a Chrome extension that summarises web articles using AI.
TL;DR: If you sign in with Google, article text goes through our servers on its way to Anthropic, but we do not store it. If you bring your own API key, your key is stored locally and article text is sent directly from your browser to Anthropic without passing through our servers.
Data collection
Such Summary does not use cookies or tracking technologies, and does not collect general product analytics such as page views or click tracking. What reaches us depends on the mode you choose:
- Sign-in mode: you sign in with Google. We store the account information needed to keep you signed in, such as your email address and session tokens. Article text is sent to our summarisation server for each summary request, then forwarded to Anthropic. We do not store article text. We do store operational usage data needed to enforce quotas and control spend, including per-account daily summary counts and global daily estimated token/cost totals.
- API-key mode: you provide your own API key. Your article text and API key do not pass through our servers for summarisation.
API keys
In API-key mode, you provide your own Anthropic API key. Your API key is stored locally on your device using Chrome's built-in storage API (chrome.storage.local). It is never synced across devices and is never sent to us. It is sent only to Anthropic when making summary requests.
Article content
When you request a summary, the extension extracts article text from the current page. In sign-in mode, that text is sent to our summarisation server, forwarded to Anthropic, and returned to your browser. We do not store the article text or the generated summary. In API-key mode, the text is sent directly from your browser to Anthropic.
Settings sync
Non-sensitive settings (summary preferences and custom prompts) are stored using chrome.storage.sync, which Chrome may sync across your signed-in devices via your Google account. API keys are explicitly excluded from sync.
Model configuration
The extension periodically fetches a small JSON file from summariser.hartreeworks.org to check for updated default Anthropic model IDs. This allows us to automatically give you access to the latest supported Anthropic models as they become available, so you always get the best possible summaries without needing to update the extension. This request contains no personal data, no API keys, and no article content — it is a simple GET request that returns a list of model names.
Usage data
In API-key mode, the extension maintains local usage logs (token counts per request) stored in chrome.storage.local on your device. These logs are never transmitted anywhere. You can view and clear them from the settings page.
In sign-in mode, the proxy stores server-side usage counters so we can enforce free account quotas and shared-key spend limits. These counters include your daily summary usage count and aggregate daily estimated input tokens, output tokens, and cost. They do not include article text, page URLs, article titles, or generated summaries.
Third-party services
In sign-in mode, article content is sent to Anthropic via our summarisation server. In API-key mode, article content is sent directly from your browser to Anthropic. Anthropic has its own privacy policy:
Permissions
The extension requests the following Chrome permissions:
- activeTab — to read the current page's content when you activate the extension.
- storage — to save your settings and API key locally.
- scripting — to inject the content script that extracts article text and displays summaries.
The api.anthropic.com host permission is required to make API calls directly from the extension in API-key mode. The summariser.hartreeworks.org permission is used for sign-in mode summarisation, account usage checks, and Anthropic model configuration. The extension also requests broad page access so it can extract article text from the current page when you activate it.
Changes to this policy
If this policy changes, the updated version will be published at this URL. Material changes will be noted in the extension's changelog.
