What we collect

Mentoku does not collect personal data. Gameplay happens on your device.

SmartRefresh stores your refresh settings locally in your browser and does not collect personal data.

MarkGrab does not collect personal data. It runs 100% client-side — page content is converted to Markdown locally in your browser and never sent over the network. Settings are stored locally via Chrome's storage API. Full privacy policy →

CleanJSON does not collect personal data. It runs 100% client-side — JSON is parsed and rendered locally in your browser and never sent over the network. It has no settings to store. Full privacy policy →

SEO Exporter reads SEO metadata from the page you're viewing entirely in your browser. Its batch audit feature (Pro) fetches only the URLs you provide, and a Pro license key is validated directly against Lemon Squeezy, our payment processor. It does not track you across sites or sell your data. Full privacy policy →
