Glowmark - Privacy Policy
Last updated: 26 September 2026. Glowmark is a browser extension by Nightdrive Labs for highlighting web pages and PDFs.

What Glowmark stores

Your highlights, notes and their page addresses are stored only in your own browser (the extension's local storage).
They are never sent to us or to anyone else. Uninstalling the extension deletes them.

What Glowmark does not do

Glowmark does not collect analytics, does not track your browsing, does not show ads, and does not sell or share any
personal data. Page content is read only to draw highlights on the page you are viewing.

Payments (Glowmark Pro)

If you start a free trial or buy Glowmark Pro, payment and account status are handled by ExtensionPay
(privacy) and Stripe (privacy).
They receive the email address and payment details you enter; Glowmark only asks ExtensionPay whether your account is
paid or in its trial period.

PDFs

PDFs you open in Glowmark are downloaded directly by your browser from their original address, or read from the file
you choose. They are not uploaded anywhere.
