WNF Companion Extension — Privacy Policy

Effective Date: June 6, 2026

This Privacy Policy describes how the WebNovelFinder Companion browser extension (the "Extension") handles your data. It is a companion to your WebNovelFinder.com account (the "Site" or "WNF") and is published by the same team. This policy covers only the extension itself; the handling of your WNF account, reading lists, reviews, and other site features is governed by the main WebNovelFinder Privacy Policy, which this policy supplements and does not replace.

The Extension exists to do one thing: when you read a chapter on a supported web novel site, it notes the chapter URL and tells your WNF account so your library stays in sync with where you actually are in each story. It is read-only on the pages you visit, runs no ads, and shares nothing with third parties.

This policy applies to every install of the Extension from any official distribution channel (Chrome Web Store, Microsoft Edge Add-ons, Mozilla Add-ons / AMO, Apple App Store via Safari Extensions). The behavior described here is the same across all of them — the Extension is built from a single TypeScript codebase with only per-browser packaging differences.

The Extension's content script runs only on the WebNovelFinder site and on the set of third-party web novel reading sites that WebNovelFinder currently supports. That set is declared up-front in the Extension's host_permissions manifest, so your browser shows you the exact list of sites at install time and again whenever that list changes. The set evolves as WNF adds or removes platform coverage; each change ships as a new extension version with the updated list. No runtime permission requests are made — the Extension cannot quietly extend its reach without your browser asking you to re-grant access.

On those sites, the Extension reads:

• The URL of the chapter page you are currently viewing (so the server can match it to the corresponding novel + chapter in your library).
• The chapter label or title visible on the page, where the layout reveals it, used purely to improve the matching accuracy.

The Extension does not read:

• The text content of the chapter you are reading.
• Your scroll position, mouse position, clicks, or any other interaction on the page.
• Any other tab, window, or site outside the declared host list.
• Page contents from any site not in the manifest (the content script is scoped to the declared hosts; nothing else is touched).

Every request the Extension makes is sent over HTTPS to webnovelfinder.com only. Each request includes:

• The chapter URL described in Section 2, so the server can match it to the corresponding novel and chapter in your library and record your reading position.
• An authentication credential identifying your WNF account, so the server knows which account the action applies to.
• For shelf and library actions you take in the popup (add to shelf, remove a novel, browse your library), the corresponding novel and shelf information.

The Extension does not transmit page-content excerpts, browser fingerprints, IP-geolocation data, or any other data from your browsing activity beyond what these features require. It embeds no third-party analytics, advertising, or telemetry beacons (see Section 4).

None. The Extension does not embed third-party scripts, analytics SDKs, advertising networks, error-monitoring services, or any other external code. Every network request goes to webnovelfinder.com over HTTPS.

Inside your browser's local extension storage (sandboxed per-extension; not accessible to web pages), the Extension keeps:

• Preferences: theme choice, notification opt-ins, and similar user-controlled settings.
• A cached snapshot of your WNF shelves so the popup can open instantly without a network round-trip. Refreshed on demand.
• A sign-in credential that authorizes the Extension to act on your behalf. The credential is kept in your browser's secure extension storage with a layer of obfuscation, but the obfuscation is a deterrent rather than a strong defense — anyone with access to your browser profile could in principle recover it. Treat your browser profile with the same care as your account password. The stronger protections live on the server: WebNovelFinder never stores the credential in a readable form, and you can cancel it at any time (see Section 6).

You authorize the Extension by signing in on webnovelfinder.com once. The Extension never sees your password — it receives a sign-in credential after you approve the consent screen. That credential lives in your browser locally (as described in Section 5) and remains valid until you revoke it. You stay signed in across browser restarts and updates; you will not be prompted to re-authorize on a schedule.

You can revoke the credential at any time:

• From the Extension's popup, by signing out.
• From your WNF account at Account Settings → Connected apps, by clicking Disconnect.

Revocation is immediate. The next request the Extension makes will fail authentication and stop syncing.

The Extension is intended for users 13 years of age or older, matching the WebNovelFinder account requirement. We do not knowingly collect data from children under 13. See Section 8 of the main Privacy Policy for details.

You retain all the rights described in the main WNF Privacy Policy (access, correction, deletion, objection). Specific to the Extension:

• Uninstall the Extension at any time from your browser's extensions page — this stops all data collection by the Extension on your device.
• Revoke the bearer token as described in Section 6 to stop the Extension from communicating with your WNF account.
• Request deletion of any reading-position data the Extension has stored against your WNF account by emailing the contact address in Section 10.

Material changes to how the Extension handles your data will be announced via an in-extension notice and shipped in a new extension version that you must accept to continue using. Non-material changes (clarifications, typo fixes, contact updates) are made in place; the Effective Date at the top of this page reflects the latest revision.

Questions, deletion requests, or concerns about this policy: [email protected].

This policy is intentionally narrow — it covers only what the Extension does on your device and in transit to webnovelfinder.com. Account-level data handling (how WNF stores your email, reviews, lists, recommendations, and analytics on the site itself) is described in the main WebNovelFinder Privacy Policy. Where the two policies overlap (e.g., your bearer token is also referenced in the main policy's Connected Apps section), the more specific terms in this document govern Extension behavior.
