All file processing happens entirely in your browser using WebAssembly and JavaScript. Your files are never transmitted to Doclair servers or any third-party servers. This is an architectural guarantee — not a policy.
We use Google Analytics for anonymous, aggregate page view and usage statistics, and Microsoft Clarity for session-replay heatmaps that help us improve the interface. Neither service has access to your files. We collect no file content, no personal identifiers, and no usage patterns at the file level.
Google Analytics and Microsoft Clarity may set first-party cookies for anonymous visitor analytics. We do not set any advertising or third-party tracking cookies. The only additional browser storage we use is for app preferences (theme, settings) stored locally on your device.
For AI-powered tools (Chat with PDF, AI Summarizer), only extracted text from your PDF is sent to our API route, which then calls an AI language model. The PDF file itself never leaves your device. Text is not stored beyond the duration of your session.
All file data loaded into browser memory is automatically cleared when you close the browser tab. We have no persistent storage of your document content.
We do not sell, share, or license your data to any third party. We do not use advertising networks or data brokers.
