Extension permissions
Nookspan asks only for the browser access needed to turn supported Facebook property posts into a private local map.
Facebook page access
The extension loads on Facebook to detect navigation into groups without a page refresh. In a group it recognizes supported property cards and their engagement. Opening the map automatically retrieves photos and listing details through your existing Facebook session. Nookspan does not inject a script on unrelated websites.
Storage
Keeps saved groups, listing details, favorites, and temporary image references in extension-owned local storage. Listing records are retained for up to 30 days.
Alarms
Checks pending Stripe payments and refreshes an active pass. These checks send only payment verification information; they do not read Facebook or upload saved listings.
Website connection
Access to the Nookspan website enables payment verification. Only the configured website can check your plan, initiate checkout, activate a pass or open saved groups. The extension does not request the general tabs permission.
Images and maps
Facebook CDN access displays listing photos. OpenStreetMap access displays map tiles. Locations are approximate and remain labeled as such.
Active tab
Lets the extension confirm that the Facebook group you currently have open contains supported listing posts before showing the Nookspan viewer.
