1. Scope

This notice covers the website lightningeg.com (the “site”), in English and Arabic.
It does not cover the Lightning app. The app has no account and no analytics, and keeps financial data only on your own devices.
The app connects to the internet only to look up prices of holdings you record.

Applies to every visitor.
Provider: GoatCounter, an open-source analytics service.
Collected: the page viewed, the referring site, screen size, browser language and the page’s release ID.
Collected: downloads by build, clicks on buttons and links, enlarged screenshots, sections scrolled into view, calculator use, questions opened, and whether a form was started or submitted.
Not collected: the contents of any field, including amounts entered in the calculator.
Nothing is stored on your device.
GoatCounter may tell page views of one session apart for a few hours, using a temporary value derived from your connection. It does not store your IP address.
Results are totals. A daily copy of the totals is published in the site’s public code repository.

Applies only if you select Allow all. It uses your browser’s storage, which works like a cookie.
Your browser creates a random visit identifier, held in session storage and deleted when the tab is closed.
Your browser creates a random visitor identifier, held in local storage for 90 days, to tell first visits from return visits.
Each page sends the events listed in section 2, with these identifiers, the page, device type (phone, tablet or desktop), language, referring site and campaign tags (utm_source, utm_medium, utm_campaign).
The data is sent to a Google Apps Script run by Lightning and stored in a private Google Sheet.
Records older than 90 days are deleted daily.
Only totals are exported from the sheet.

To request deletion, use the feedback form on Downloads.

Essential analytics apply until you choose.
Your choice and your light or dark theme setting are stored in this browser’s local storage, which works like a cookie. They apply to this browser only.
