About & security
Learn how 66PDF handles uploaded PDFs, summaries, and account information.
Before using the service, make sure you have the right to upload a document. Do not upload confidential material you would not share with an online service.
01
Your PDF may be sent to services that provide storage, text processing, or AI generation so 66PDF can complete the summary or question-answering request. File content or extracted text may be handled temporarily during processing.
02
Summaries created while signed in are associated with your account so you can view and manage history. Guest trials and signed-in history have different capabilities; follow the features and terms shown in the product.
03
Remove unnecessary personal information before uploading, avoid highly sensitive or confidential material, sign out on shared devices, and delete items from history when needed.
04
No online service can promise absolute security. Consider the sensitivity of each document and review the third-party storage, processing, and AI services that 66PDF relies on.
