5. Do Not Track

Some browsers include a "Do Not Track" (DNT) feature that signals to websites that you do not want to be tracked. There is currently no universal standard for how companies should respond to DNT signals. Kerplexir does not currently respond to DNT signals, but we limit tracking to the analytics tools described above and do not engage in cross-site tracking for advertising purposes.

6. Updates to This Policy

We may update this Cookie Policy from time to time to reflect changes in technology, legislation, or our data practices. We will post the updated policy on this page with a revised "Last updated" date.
