DuckDuckGo provides a search engine focused on online privacy. It does not track users or collect search history, offering a private and secure browsing experience. The product works by delivering search results and monetizing through non-tracking ads and affiliate partnerships with e-commerce sites, plus educational content via SpreadPrivacy to help users learn about privacy. This approach differentiates it from competitors that monetize through tracking and personalized ads, by prioritizing user anonymity and transparency. The company aims to give people control over their personal information online and establish trust through privacy-focused search and education.

Claude 4.5 Opus and the personal Encyclopedia security risks. Jeremy (whoami.wiki) has utilised Claude 4.5 Opus and the Claude Code CLI to synthesise fragmented personal data into a structured MediaWiki instance. By cross-referencing Uber logs, bank statements, Marcus Webb Senior Backend Analyst The pitch. Jeremy (whoami.wiki) has utilised Claude 4.5 Opus and the Claude Code CLI to synthesise fragmented personal data into a structured MediaWiki instance. By cross-referencing Uber logs, bank statements, and Shazam history, the project reconstructed a detailed narrative of a Mexico City trip (Source: Tech Times, March 26, 2026). It demonstrates the high-end reasoning capabilities of the current Claude 4 series. Under the hood. Claude 4.5 Opus currently holds the benchmark lead for long-context reasoning as of February 2026 (Source: Anthropic Transparency Hub). This enables the model to ingest thousands of lines of raw CSV and GPS data to identify patterns that previous generations missed. Many large-scale organisations, including Notion, DuckDuckGo, and Quora, now integrate these models into their core workflows. See Claude profile However, the security implications of this "Personal Encyclopedia" are significant. Claude Code, the agentic tool used to manage the project, is subject to CVE-2026-21852. This vulnerability allows for remote code execution through manipulated settings files (Source: Dark Reading). Furthermore, OWASP 2026 has documented "HITL Dialog Forging," where users habitually approve agentic prompts without verifying the underlying commands. Privacy remains a primary concern for backend architects. Since late 2025, Anthropic's policy dictates that consumer data from Pro and Max tiers is used for training by default unless users manually opt out (Source: char.com, March 2026). Feeding raw financial transactions and location history into a proprietary cloud model creates a permanent, searchable record of a user's private life. Several technical details remain opaque. Usedby do not know the specific system prompts required to maintain consistency across the MediaWiki architecture (UsedBy Dossier). More importantly, there is no public verification that Anthropic effectively purges these large-scale personal data uploads after the standard 30-day retention period for non-training accounts. Marcus's take. This project is a sophisticated way to gift-wrap your digital soul for a future data breach. While the reasoning density of Claude 4.5 Opus is technically superior for indexing messy logs, the combination of CVE-2026-21852 and Anthropic's "opt-out" training policy makes this a non-starter for production or personal use. If you value your operational security, keep your bank statements and GPS coordinates out of the cloud and stick to local-first analysis. Ship clean code, Marcus.

Cloaked, consumer privacy platform generating virtual personal identities. Here you'll find information about their funding, investors and team.
Cloaked, a consumer-focused privacy company offering bundled security solutions, has raised $375 million in Series B funding and growth financing led by General Catalyst and Liberty City Ventures. Participants include Lux Capital, Human Capital, and DuckDuckGo. Founded in 2020 by brothers Arjun and Abhijay Bhatnagar, Cloaked provides multiple identities, data removal, identity theft insurance, VPN, and AI-powered call screening. The company saw 10x growth last year and now serves over 350,000 paying customers, protecting 10 million identities and processing over 50 million spam calls. The funding will support expansion into enterprise security, offering employees identity and password management with scam alerts. Cloaked is also developing AI-powered screening for text, email and browsing, plus an AI agent for automated security actions.
DuckDuckGo adds private AI photo editing to Duck.ai platform. DuckDuckGo has expanded its Duck.ai platform with a new AI-powered photo-editing feature that lets users modify images while preserving anonymity. The company says all image prompts are anonymized and never used to train underlying AI models, continuing its privacy-first approach to generative AI. The announcement positions the update as an optional enhancement to Duck.ai's existing text and voice capabilities. Users can now upload an existing image to the AI image generator and apply edits through natural language prompts. To access the feature, users select "New Image" and then "Start With An Image," after which they can upload JPEG, JPG, PNG, or WebP files. DuckDuckGo states that uploaded images are stored locally on the user's device rather than on its servers. As with text and voice interactions on Duck.ai, the company removes metadata that may contain personal information, such as IP addresses, before forwarding prompts to third-party model providers. These providers currently include Anthropic, Azure OpenAI, OpenAI, Meta, and together.ai. According to the Duck.ai Privacy Policy, DuckDuckGo does not store prompts or outputs on its own servers. By default, recent chats are saved locally in the user's browser, unless the user opts out. Local chat history can be deleted individually, cleared using the platform's "Fire Button," or automatically removed after 30 conversations. Browser settings may also affect how long local data is retained. Crucially, DuckDuckGo says it has contractual agreements with its model providers prohibiting them from using submitted prompts or generated outputs to train or improve their AI models. Providers are also required to delete any received data once it is no longer necessary to generate a response, and in most cases, within 30 days, except where limited retention is required for legal or safety compliance. Founded in 2008, DuckDuckGo is best known for its privacy-focused search engine, which positions itself as an alternative to data-driven advertising platforms. The company has steadily expanded its product portfolio to include a privacy-centric browser, tracker blocking tools, subscription services, and, more recently, AI features through Duck.ai. Its approach contrasts with many mainstream AI services, which require account sign-ins and may use user data to improve their models. The photo editing feature builds on DuckDuckGo's recent rollout of real-time AI voice chat, which also routes audio through an encrypted relay and avoids storing recordings. In that implementation, voice data is streamed ephemerally and neither DuckDuckGo nor the model provider retains it after a session ends. Duck.ai's terms of service impose several usage restrictions on the new image capabilities. Prohibited uses include generating photorealistic images of real people without their consent, creating deepfakes or non-consensual intimate imagery, and producing illegal, harmful, or sexually explicit content. The service also blocks use in regulated or high-risk domains such as medical, financial, or legal advice, and includes safeguards designed to prevent misuse. For users who prefer to avoid AI features altogether, DuckDuckGo also introduced a dedicated no-AI search interface at noai.duckduckgo.com. This version of the search engine removes AI-generated summaries, Duck.ai prompts, and related interface elements, while automatically applying the company's AI image filter to search results.
DuckDuckGo enables AI voice chat without saving voice data. DuckDuckGo has added voice chat to Duck.ai, allowing users to speak to an AI assistant while keeping audio private, unrecorded, and excluded from AI training. Voice chat is available in the DuckDuckGo browser and most third-party browsers, with support for Mozilla listed as coming soon. According to the company's help page, "DuckDuckGo limits access to audio streams and voice data so they are available only to OpenAI, the model provider for voice chats, and only... More
