Mark-Up-Timer is a local-first Chrome extension for capturing timestamped review notes and copying a Markdown checklist.
Timer state, timestamped notes, page origin, preferences, and the cached license entitlement are stored in Chrome extension storage on your device. The extension does not transmit review notes or webpage content to el-two LLC.
The packaged content script runs on normal webpages so the floating timer can appear where you are reviewing work. It does not collect page content, passwords, form data, cookies, or browsing history. Gumroad pages are excluded.
When you activate or re-check a license, Mark-Up-Timer sends the entered license key and fixed product ID to Gumroad’s HTTPS license verification API. Gumroad handles checkout and payment details externally.
Markdown is written to the clipboard only after you click Copy. The extension has no analytics, advertising, account system, cloud database, or remotely hosted executable code.
