適用範囲
SiteEgress helps users inspect and understand browser-visible privacy and data-flow behavior on websites they visit. It reports destinations, known services, form metadata, permission requests, browser-fingerprinting-related signals, Cookie names, browser-storage key names, security context, and optional country-level network-location estimates.
SiteEgress is an inspection and transparency tool. It is not an antivirus product, legal compliance certification, proof of malicious intent, or guarantee that a website does not collect data.
処理する情報
To produce an audit, packaged content scripts and the extension service worker may process the current page origin and hostname; destination hostnames; resource types and transfer channels; request methods; form action, method, field count, password-field presence, and broad field-name categories; Cookie names; Local Storage and Session Storage key names; permission events; fingerprinting-related API events; and selected page-security metadata.
SiteEgress does not intentionally retain typed form values, passwords, Cookie values, browser-storage values, authorization headers, request or response bodies, complete query strings, or URL parameter values.
Reports contain evidence metadata, not the private values users type into websites.
実行時のデータ最小化
SiteEgress はサニタイズされた制限付き URL パラメーター名だけを分類し、値は検査しません。
ページイベントは種類別スキーマに投影し、許可リスト、サニタイズ、上限を適用します。DOM 変更検出も増分かつ制限付きです。
Geo Insights が有効な間だけ応答オブザーバーを登録し、無効化時は解除して進行中の検索を中止します。
ローカルのサービス情報
サービスカードは内蔵のディレクトリとローカルのドメイン照合を使用し、バックグラウンドでディレクトリを問い合わせません。公式資料を開く操作は、利用者による第三者サイトへの移動です。
保存した訪問基準
利用者が明示的に保存し、最大40オリジン、各オリジン4場面につき1件を保持します。削除、置換、上限による削除、アンインストールまで保持します。
保持するのはオリジン、ホスト名、分類、件数、スコア、範囲、時刻のみです。パス、パラメーター値、ページやリクエスト本文、入力値、生のIPは保存しません。
チェックポイントと証跡
同一オリジンの二つの最小化された証拠窓を比較します。プライバシーまたはCookieの選択操作はユーザー自身が行います。
保存対象はオリジン、時刻、スコア、カバレッジ、送信先、既知サービス、集計シグナル、推定国コード、GPC/DNT状態などに限られます。個人値、ページ本文、生IPは含まれません。
保存はサイトごと8件、全体40サイトに制限されます。ローカルHTML証跡は明示的な出力時だけ作成され、法的な同意遵守を証明しません。
1.2ではChrome権限を追加していません。
プライバシー選択テスト
サイトの選択操作は利用者自身が行います。選んだサービス、出現の期待、10–120秒の観察期間を記録します。設定はセッション内、最大40タブに限り、120秒を超えた古い期間は無視します。
結果は対応するブラウザー上の観察であり、法令順守の証明ではありません。観察されないことは収集の停止を証明しません。
最小化された診断
診断は要求時にのみ生成・出力し、収集とローカル設定の状態を示します。出力にサイトのオリジンやホスト名は含みません。必要な送信先メタデータを含み得る監査レポートや基準とは別です。
Geo Insights
Geo Insights is optional and disabled by default. When a user enables it, SiteEgress may use Chrome's browser-visible response metadata to obtain a destination server IP address. Local and private addresses are classified on the device. A unique public destination-server IP may be sent to ipwho.is solely to obtain a country code and continent code.
The lookup request does not include page text, form values, the full page URL, Cookie values, report contents, or user account information. The raw destination IP is kept only transiently in service-worker memory, is deduplicated to reduce lookups, and is not written to reports, local history, exports, or persistent extension storage.
A displayed country is an estimate of the network server location observed by Chrome. CDN routing, anycast, proxies, caches, load balancers, and multi-region infrastructure can change the apparent country. Geo Insights does not prove legal data residency or where an organization ultimately stores or processes data.
Third-party lookup: ipwho.is. Geo Insights stays off until the user explicitly enables it.
任意のローカルブリッジ
SiteEgress can connect locally to the separately installed Agent Guard extension. The bridge is disabled by default in both products and requires explicit opt-in on each side.
Shared fields are limited to normalized origins or destination hostnames, known service/action categories, aggregate scores and counts, policy outcomes, confidence, and bounded evidence metadata. Page text, typed values, passwords, secrets, Cookie or Storage values, request bodies, URL parameter values, and raw destination IP addresses are excluded.
Agent Guard context cannot change a SiteEgress audit. SiteEgress context cannot approve, grant, block, or otherwise control an Agent Guard action. The products remain independently installable and usable.
The bridge adds no Chrome API permission and sends no bridge data to a developer server.
ローカル保存と保持
Live reports are stored in chrome.storage.session and normally disappear when the browser session ends or the tab report is removed. User preferences are stored in chrome.storage.local.
Local history is optional. If enabled, compact snapshots may include the site origin or hostname, score, destination hostnames, known service names and categories, aggregate signal counts, country-code aggregates, and save time. Raw IP addresses and private field values are not included. Users can clear history at any time.
レポートと出力
A user can export the current report as JSON, CSV, standalone HTML, or a printable page that can be saved as PDF. Exports are created on the user's device and are not uploaded to SiteEgress.
Exports can contain site hostnames, third-party destinations, known service names, evidence labels, scores, and country-code aggregates. Users should review an export before sharing it outside their device.
権限とサイトへのアクセス
storage keeps session reports and user-controlled local settings. sidePanel displays the audit beside the page. webRequest observes non-blocking response metadata required for optional Geo Insights. HTTP and HTTPS host access lets packaged content scripts inspect normal websites from document start and lets webRequest receive response metadata.
SiteEgress does not request webRequestBlocking, declarativeNetRequest, notifications, cookies, history, downloads, tabs, or remote-code permissions. It cannot inspect Chrome internal pages or the Chrome Web Store.
選択と削除
You can leave Geo Insights, the companion bridge and history disabled, pause or reset an audit, delete or replace visit baselines, clear checkpoints and history, cancel a privacy-choice test, delete your exported files, or uninstall the extension. These controls operate on separate features and storage namespaces.
Disabling Geo Insights removes its response observer and clears current location aggregates and pending lookup state. Disabling either companion bridge stops new summary exchange. Uninstalling removes Chrome-managed extension storage; files you exported remain on your device until you delete them.
