Do I need an account?
No. None of the Quire readers has accounts or sign-in. Install one from the Chrome Web Store and open a file.
Are my documents uploaded anywhere?
No. Files are opened and processed in your browser, and anything kept for later, such as a library, recovery copy or recent document, is stored in your Chrome profile. When you open a document from a web link, the request goes to the site that hosts it, the same as downloading it.
Why are these three extensions and not one?
Each job needs different access. Opening every .epub link on the web needs broad site access, while the PDF and Markdown readers only ask for a website when you open something from it. Keeping them separate means you only grant what the reader you use actually needs.
Can Quire PDF edit the text in a PDF?
Not the original text. It adds highlights, notes, text, drawings, images and signature marks, fills existing form fields, and rearranges pages. It does not do OCR, secure redaction or certificate-based digital signing.
When can I install Quire Markdown?
It has been submitted and is waiting for Chrome Web Store review. An install button will appear here once it is approved. Until then, its website describes what it does.
What does it cost?
All three are free, with no ads. Quire EPUB Reader and Quire PDF are on the Chrome Web Store now; Quire Markdown can be installed once its review finishes.
Does browser storage replace a backup?
No. Uninstalling an extension or clearing browser data can remove what it stored. Keep your original files, and download copies of edited PDFs you care about.
