This Privacy Policy explains how PDFdigest collects, uses, stores, and shares information when you use the website and submit paper comprehension requests.
1. Data We Collect
- Account data: email address only.

2. How We Use Data
We use data to operate the service, authenticate users, analyze papers, generate learning outputs, provide request history, send service emails (such as queue and completion notifications), secure the platform, and troubleshoot failures.
3. Authentication and Sign-In Data
For local account sign-in, we process account credentials and session cookies through WordPress authentication.
If Google sign-in is enabled, we access email address only for authentication and account linking.

5. Legal Basis and Retention
We process data where necessary for contract performance, legitimate interests, legal obligations, or consent where required.
Retention summary: user email is retained while an account is active; guest files are deleted periodically; registered-member files are retained indefinitely unless deleted by the user from the dashboard or through account deletion.
6. Sharing and Processors
We may share data with service providers that support hosting, email delivery, authentication, and AI processing infrastructure. Where external processing APIs are used, uploaded files and request metadata may be transmitted to those processors to complete your request.
7. Data Storage and Protection
We apply technical and organizational safeguards, including validation, controlled access to infrastructure, and credential restrictions. No system can be guaranteed fully risk-free.
8. Cookies and Session Data
We use essential cookies and session mechanisms for login state, request security, and core website functionality. Disabling essential cookies may prevent parts of the service from working.
