Cookie Policy
Last updated: 15 May 2026
This Cookie Policy describes the cookies and similar technologies used by vAInz Sport Analysis ("vAInz", "we", "us") on vainz.com and the related application (the "Service"). For information on how we handle personal data more broadly, please refer to our Privacy Policy.
1. What are cookies
Cookies are small text files placed on your device when you visit a website. They are used to remember your preferences, keep you signed in, measure usage, and provide essential functionality. We also use similar technologies such as localStorage and sessionStorage entries handled by your browser — for the purposes of this Policy, these are treated together with cookies.
2. Categories of cookies used
- Strictly necessary — required for the Service to function. These cannot be disabled and do not require consent.
- Functional — remember non-essential preferences such as the collapsed/expanded state of the sidebar and selected interface language. These improve your experience but the Service works without them.
- Analytics — none. We do not currently use any analytics or tracking cookies.
- Marketing — none. We do not currently use advertising or third-party tracking cookies.

4. How to control or disable cookies
You may control or disable cookies at any time through your browser settings. Each browser provides its own controls — typically under Settings → Privacy & Security → Cookies and Site Data. Disabling strictly necessary cookies will prevent you from signing in or completing payment.
You can also clear all data stored by the Service from Settings → Privacy & Security → Clear browsing data → Cookies and site data (Chrome) or the equivalent option in Firefox, Safari and Edge.
