Privacy Policy

Last Updated: March 17, 2026

Overview

This Privacy Policy explains how Web Summarizer collects, uses, stores, and shares information when you use the extension, the related backend services, and connected features.

Web Summarizer is a browser extension that summarizes web pages, explains selected text, supports chat-style follow-up questions, optionally lets users sign in with Google, and includes optional YouTube and PDF helper features.

By using Web Summarizer, you agree to the practices described in this policy.

What We Collect

We collect only the information needed to operate the extension and related services.

1. Information stored locally in your browser

Depending on which features you use, the extension may store the following in Chrome storage:

• Extension settings and preferences, such as sidebar width, font size, output format, output language, and UI preferences.
• Optional third-party service settings you enter, such as a DumplingAI API key, DumplingAI endpoint, or PDF conversion endpoint.
• A locally stored authentication token after sign-in.
• A locally generated device ID used for abuse prevention and rate limiting.
• Local chat history for the current page, including recent prompts, assistant responses, compressed summaries, and optional image data.

Some settings are stored using Chrome sync storage and may sync across browsers logged into the same Chrome profile. Auth tokens, device IDs, and page chat history are stored locally on the device.

2. Information sent to our backend

When you use summarization, explanation, chat, review, or sign-in features, the extension may send information to our backend, including:

• Page URL and page title.
• Page content, selected text, chat prompts, and chat context.
• Browser UI language and technical request metadata.
• A locally generated device ID.
• Authentication token or Google access token when you sign in.
• Review submissions, such as rating and review text.
• Optional screenshot image data if you use image-based chat or screenshot features.
• Chat history cache data, including recent messages, summaries, and optional image data.

3. Account information

If you sign in with Google, we may process and store:

• Google account ID.
• Email address.
• Display name.
• Profile image URL.

If your account has paid access or credits, we may also store account-related service data such as plan, credits, subscription status, or related billing status metadata.

4. Usage, security, and abuse-prevention data

To operate the service, enforce usage limits, and prevent abuse, we may process and store:

• IP address.
• User-Agent string.
• Country or region information derived from requests.
• A hashed fingerprint derived from request metadata and device ID.
• Request counters and timestamps.
• Fraud or abuse flags.

5. Feedback and reviews

If you submit a review through the extension, we may store:

• Your rating.
• Your written feedback.
• Your associated account information if you are signed in.

How We Use Information

We use information to:

• Provide summarization, explanation, chat, translation, and related AI-assisted features.
• Authenticate users and maintain signed-in sessions.
• Enforce free and paid usage limits.
• Save and restore chat history for the current page.
• Process optional screenshot, image, YouTube, and PDF features.
• Improve reliability, troubleshoot failures, and detect abuse.
• Display reviews and operate account or admin functionality.
• Comply with legal obligations and protect users, the service, and the public.

We do not sell your personal information.

We do not use or transfer your data for purposes unrelated to Web Summarizer's core functionality.

We do not use or transfer your data to determine creditworthiness or for lending purposes.

When Information Is Shared

We share information only as needed to provide the service or comply with legal obligations.

1. Our backend and infrastructure

Extension requests are sent to our backend service to provide summarization, chat, account, review, and chat-history features.

2. AI and feature-processing providers

Depending on the feature you use and the current backend configuration, information may be sent to third-party processors such as:

• Vercel AI Gateway and the AI model provider used behind that gateway.
• OpenAI-compatible API providers used by the backend.
• Google, for Google sign-in token verification.
• DumplingAI, if you use YouTube transcript extraction and have configured that feature.
• A PDF conversion service endpoint, if you use PDF conversion.

These third parties process data under their own terms and privacy policies.

3. Legal and safety reasons

We may disclose information if required by law, legal process, or a good-faith belief that disclosure is necessary to protect rights, safety, security, or investigate abuse.

4. Business changes

If ownership of the service changes, relevant data may be transferred as part of that transaction, subject to applicable law.

Data Retention

We retain data for different periods depending on the feature:

• Local browser settings remain until you change them, clear browser extension storage, or uninstall the extension.
• Locally stored chat history remains until you clear it or uninstall the extension.
• Backend chat history cache is designed to expire after approximately 5 hours.
• Rate-limit and abuse-prevention records may be retained for operational and security purposes.
• Account, review, and related service records may be retained as long as needed to operate the service, comply with legal obligations, resolve disputes, and enforce policies.

Cookies and Tracking

The extension does not use cookies, advertising pixels, or third-party analytics SDKs inside the extension for advertising purposes.

However, our backend may process technical request data such as IP address, device ID, user agent, and request timestamps for security, abuse prevention, rate limiting, and service operations.

Security

We use reasonable administrative, technical, and organizational measures to protect information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Your Choices

You can:

• Uninstall the extension at any time.
• Clear locally stored extension data through Chrome extension storage or the extension UI where available.
• Sign out of your account and remove locally stored auth tokens.
• Avoid using optional features such as Google sign-in, screenshot-based chat, YouTube transcript extraction, or PDF conversion.

If you want account-related data deleted or have a privacy request, contact us using the methods listed below.

Children's Privacy

Web Summarizer is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

International Processing

Your information may be processed in countries other than your own, including by infrastructure providers and third-party processors that support the service.

We may update this Privacy Policy from time to time. We will update the date at the top of this document when changes are made.
