Comparison data
When you save a comparison, StackOZ stores your answers, ranked results, evidence version, and a random identifier generated in your browser. StackOZ does not ask for your newsletter subscriber list or import its contents.
Decision files
A saved result can create a downloadable JSON decision file. The file contains the same comparison profile and results shown to you; it does not contain subscriber records.
Measurement
StackOZ records events such as comparison engagement, completion, saves, and outbound provider clicks. Events include a random session ID, page type, page path, first-touch UTM values, and the hostname of an external referrer when available. StackOZ does not store the full referrer URL for this measurement. These events are used to find friction and improve decision value—not to manufacture a score. Contact form submissions include your message, an optional reply email, and a page URL if supplied. Do not send subscriber data.
Browser storage
Your browser stores a random visitor identifier so the site can find saved comparisons. It also keeps a temporary random analytics session and its first-touch attribution in session storage; that session rotates after 30 minutes without activity. Use the control below to delete server records linked to the visitor identifier before clearing storage.
Retention and deletion
Saved comparisons and linked events remain available until they are deleted through the browser control below or removed as part of routine product maintenance. Contact submissions linked to this browser identifier are also deleted by that control. StackOZ does not use this data to build an advertising profile.
Delete data linked to this browser
This removes saved comparisons, generated decision files, usage events, and the random browser identifier on this device.
