# Occlira > Occlira is a desktop app for Windows and macOS that detects and removes personal data (PII) from documents, spreadsheets, email, audio and images entirely on your own computer — no cloud, no account. You anonymize a file before sharing it or pasting it into an AI tool, then restore the original values locally when you are done. Occlira runs 100% locally on Windows 10/11 and macOS. Detection uses a local AI model plus pattern rules, and audio is transcribed on-device; your files and the personal data inside them never leave your computer, and there is no telemetry by default. It supports 7 interface languages (English, German, French, Italian, Russian, Dutch, Spanish) and detects 40+ types of personal data across documents (DOCX, PDF, XLSX, EML, TXT, MD, CSV), audio (MP3, WAV, M4A, FLAC, OGG) and images (JPG, PNG, HEIC, WEBP, TIFF, BMP). For photos it can blur faces on-device and strip location/EXIF metadata. Anonymization is reversible: a mapping stored locally lets you restore the original values. It is a one-time license (from €149 for a single seat, up to €999 for a 10-seat team; the exact amount is shown at checkout) with a 14-day free trial, sold through Polar as Merchant of Record. A companion Chrome extension (included with the license, requires the desktop app) anonymizes text and attachments inside ChatGPT, Claude and Gemini. ## Core pages - [Home / overview](https://occlira.com/): what Occlira is, how it works, use cases and pricing - [Pricing](https://occlira.com/pricing/): one-time license (solo and team seats), 14-day free trial - [Download](https://occlira.com/download/): the Windows and macOS installers ## Guides and answers - [All guides](https://occlira.com/guides/): index of tasks, questions, professions and reference - [Anonymize before ChatGPT](https://occlira.com/anonymize-before-chatgpt/): remove PII before pasting into an AI tool, then restore locally - [Video: anonymize a Word document before ChatGPT (YouTube, 6 min)](https://www.youtube.com/watch?v=PQ-aNPhI2gA): the desktop workflow on screen — drop the files in, review what the model found, approve, restore the real names later; embedded in the guide above - [Remove personal data from audio](https://occlira.com/redact-audio/): local transcription + redaction of recordings - [Redact Word, PDF & Excel](https://occlira.com/redact-pii-word-pdf-excel/): remove PII from office files locally - [Remove metadata from a Word document](https://occlira.com/remove-metadata-word-document/): Document Inspector on Windows, the Mac and web limits, the author name, and what it misses - [Is ChatGPT private?](https://occlira.com/is-it-safe-to-use-chatgpt-with-confidential-data/): what OpenAI stores, who can see your chats, and the safe way to use it with confidential data - [Does ChatGPT store your data?](https://occlira.com/does-chatgpt-store-your-data/) - [Use AI without breaking the GDPR](https://occlira.com/use-ai-without-breaking-gdpr/) - [What is PII?
