Permissions and privacy

Page access

Reading and accessibility tools may need to inspect or modify page content and, for speech features, process selected text. Restrict access on sensitive pages when practical.

Data notes

Text-to-speech and page-reformatting products may process page text locally or remotely. Check voice, account, and cloud-processing terms before using private documents.

Pricing

Free core tools with optional paid features. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
