5. How We Store Your Consent
When you make a cookie choice, we store your preferences in a strictly necessary cookie (inkstant_consent) and in your browser's local storage. This record includes:
- Which categories you accepted or rejected
- The date and time of your choice
- The version of the cookie policy that was in effect
We retain consent records for up to 5 years for audit and compliance purposes. If we update our Cookie Policy (e.g., add new cookie categories), we will ask for your consent again.
6. "Do Not Track" Signals
Some browsers offer a "Do Not Track" (DNT) setting. There is currently no industry-wide standard for how websites should respond to DNT signals. However, when you reject analytics and marketing cookies through our consent banner, we honor that preference regardless of your DNT settings.
7. Changes to This Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in the cookies we use or for operational, legal, or regulatory reasons. We will update the "Last updated" date and, where appropriate, ask for your consent again.
