- Where files go
- A: Per the privacy policy, all Lumin servers are in the United States. Files are processed for tasks like OCR and compression, including with OpenAI and Google Gemini integrations. File copies are kept only if you upload, convert or share them. Account deletion removes files within 30 days of request, though another section says immediately.
- B: Web tools upload files to Sejda's servers and delete them automatically after 2 hours, with encryption in transit and at rest. Sejda Desktop processes files on your computer.
