Terms and Conditions

    Effective Date: February 27, 2026

    1. Acceptance of Terms

    By downloading, installing, accessing, or using DoppelBrain, including the browser extension, web dashboard, and any related services (collectively, the "Service"), you ("you," "your," or "User") agree to be bound by these Terms and Conditions (the "Terms"). If you do not agree to any part of these Terms, you must not access or use the Service.

    These Terms constitute a legally binding agreement between you and DoppelBrain Inc. ("DoppelBrain," "we," "us," or "our"). We may update these Terms from time to time in accordance with Section 16. Your continued use of the Service after any changes constitutes your acceptance of the revised Terms.

    2. Service Description

    2.1 Overview

    DoppelBrain is an AI-powered personal knowledge assistant that passively captures your web browsing activity and transforms it into a searchable, intelligent knowledge graph. The Service is designed to help you recall, analyze, and derive insights from your digital research — automatically and without manual effort.

    2.2 Core Components

    The Service consists of the following components:

    (a) Browser Extension. A browser extension that monitors and records your browsing activity, including page titles, URLs, and selected page content. The extension operates passively in the background and can be enabled or disabled at any time via the extension interface.

    (b) Web Dashboard. A web-based interface where you can view, search, filter, and explore your captured browsing data. The dashboard includes a visual knowledge graph (mindmap), browsing history timeline ("Trail"), intelligent search functionality, and category-based filters.

    (c) AI Assistant. A conversational AI interface integrated into the dashboard that allows you to query, analyze, and interact with your captured browsing data using natural language.

    2.3 Nature of the Service

    DoppelBrain is a productivity tool designed for personal knowledge management. The Service is not intended for surveillance of third parties, corporate monitoring, or any purpose other than assisting you with your own browsing research and knowledge retrieval. You acknowledge that the AI Assistant provides informational responses based on your browsing data and general knowledge, and such responses should not be treated as professional, legal, medical, or financial advice.

    3. Eligibility

    3.1. You must be at least 18 years of age, or the age of majority in your jurisdiction, to create an account and use the Service.

    3.2. If you are using the Service on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.

    3.3. You may not use the Service if you have been previously suspended or terminated from the Service by DoppelBrain.

    4. User Account

    4.1. You must create an account to use the Service. You agree to provide accurate, current, and complete information during the registration process.

    4.2. You are solely responsible for maintaining the confidentiality of your account credentials, including your password and any authentication tokens.

    4.3. You are responsible for all activities that occur under your account, whether or not you have authorized such activities.

    4.4. You agree to notify DoppelBrain immediately of any unauthorized use of your account or any other breach of security.

    4.5. DoppelBrain shall not be liable for any loss or damage arising from your failure to comply with the security requirements set forth in this section.

    5. Data Collection and Browsing Activity

    5.1 What We Collect

    When the browser extension is enabled, DoppelBrain collects information about your browsing activity, which may include page URLs, page titles, selected text content, headings, timestamps of visits, and interaction metadata (such as clicks, copy actions, and hover events). The specific categories of data collected are described in detail in our Privacy Policy.

    5.2 Sensitive Site Filtering (Blacklist)

    DoppelBrain maintains an extensive blacklist of approximately 20 million domains classified as sensitive, including but not limited to banking and financial services, social media platforms, payment processors, healthcare portals, adult content websites, email providers, and authentication pages. The browser extension does not track, record, or transmit any browsing activity on blacklisted domains. This blacklist is updated periodically to maintain comprehensive coverage.

    5.3 Sensitive Data Filtering

    In addition to domain-level filtering, DoppelBrain employs internal content filtering mechanisms to detect and discard sensitive personal information that may inadvertently appear within collected browsing data. If our systems identify data that appears to contain sensitive personal information — such as financial account numbers, government-issued identification numbers, health information, or authentication credentials — such data will not be stored in our systems.

    5.4 User Control Over Tracking

    You have full control over the browser extension's tracking functionality at all times. You may enable or disable tracking via the extension interface toggle. When tracking is disabled, no browsing data is collected, recorded, or transmitted.

    5.5 No Sale of Personal Data

    DoppelBrain does not sell, rent, lease, or otherwise commercially distribute your personal data or browsing information to third parties. We do not and will not monetize your browsing data through advertising, data brokerage, or any similar practice.

    6. Data Storage and Security

    6.1. DoppelBrain stores your data using industry-standard security practices, including encryption in transit (TLS/SSL) and encryption at rest.

    6.2. Access to user data within our infrastructure is strictly limited to authorized personnel and systems on a need-to-know basis, protected by multi-factor authentication and role-based access controls.

    6.3. We utilize secure, access-restricted hosting environments with continuous monitoring and regular security assessments.

    6.4. While we implement robust security measures, no method of electronic transmission or storage is 100% secure. DoppelBrain cannot guarantee the absolute security of your data and shall not be held liable for any unauthorized access resulting from factors beyond our reasonable control.

    7. Your Rights Over Your Data

    7.1 Transparency

    You have the right to view the complete information that DoppelBrain has collected about your browsing activity. This information is accessible at any time through the dashboard, including via the Trail view, History view, and by querying the AI Assistant.

    7.2 Data Deletion

    You may clear all of your browsing data at any time through the dashboard settings. This action will permanently remove all collected browsing activity, knowledge graph data, and associated metadata from our systems.

    7.3 Account Deletion

    You may permanently delete your account and all associated data at any time through the account settings in the Service. Account deletion is an irreversible action. Upon account deletion, all of your personal information, browsing data, knowledge graph data, account credentials, and any other data associated with your account will be permanently removed from our systems. DoppelBrain does not retain backup copies of deleted account data beyond the period reasonably necessary to complete the deletion process.

    7.4 Data Export

    Where technically feasible and as provided through the Service, you may request a copy of your data in a portable format. Details regarding available export options are described in the Service documentation.
