Store description excerpt

D-Schutz is a PDF reader with real, on-device AI: no accounts, no ads, no tracking, no nonsense. Most "AI" apps quietly ship your documents to someone else's server. D-Schutz doesn't. After the AI model's one-time download, every question you ask, every summary you generate, and every answer you get happens entirely on your phone. Your PDFs are never uploaded anywhere to be processed. There's nothing to sign up for and nothing watching you move between apps. Old-school, on purpose: you install it, you use it. No account wall, no ad network, no cross-app tracking, no dark patterns nudging you toward a subscription you didn't ask for. WHAT IT DOES Import any PDF and read it in a clean, full-screen viewer with smooth zoom and page navigation. When you need the gist fast, ask D-Schutz a question about the current page or the whole document, or get a summary, even for documents far longer than the AI model can normally handle, thanks to on-device retrieval (RAG) and map-reduce summarization that covers the entire file. - Import and manage a local library of PDFs - Full-screen reader with smooth zoom and page navigation - Ask questions about the current page or the entire document - Page or whole-document summaries, including documents longer than the model's context window - Streamed, token-by-token AI responses - Answers in English, Spanish, French, Portuguese, German, Mandarin, or Arabic - Open PDFs straight from other apps (file managers, email, browsers, share sheets) - Full support for password-protected PDFs HONEST PRICING D-Schutz is free to use for reading, and free to try AI on up to 3 documents. Like it? Unlock unlimited AI documents with a one-time purchase, not a subscription, no recurring charge, ever. Want to back the project further? There's an optional one-time Founding Supporter purchase too. That's the whole pricing page. No confusing tiers, no "free trial" that quietly starts billing you. THE FINE PRINT WE WON'T HIDE AI answers and summaries are generated by a language model and are advisory: they can be inaccurate. Always check anything important against the original document. Everything runs locally: - The AI models (Gemma plus a small Gecko embedding model) download once, then run entirely on-device. - No document text, question, or answer is ever sent to a server to generate a response. - The internet is used only to download those models and app updates. Want proof it's private? Turn on airplane mode. Once the AI model is downloaded, D-Schutz keeps working with zero connection, read, ask questions, and summarize with Wi-Fi and data switched off. If it still answers with the network off, nothing is being sent anywhere. D-Schutz doesn't require an account, doesn't show ads, and doesn't track you across apps or websites. Read your PDFs. Ask your questions. Nothing leaves your phone.
