4. Cookie-Free Analytics

We also use Cloudflare Web Analytics, which does not use cookies, does not collect personal data, and is loaded on all pages regardless of your cookie preferences. It provides aggregate, privacy-preserving metrics only.

5. Third-Party Cookies

The only third-party cookies on our services are set by Google Analytics (GA4) for analytics purposes. These are only loaded after you give explicit consent. We do not use advertising cookies or allow third-party ad networks on our services.

6. Managing Your Preferences

You can control cookies in the following ways:

  • Cookie banner: When you first visit, our cookie banner lets you accept or decline analytics cookies. You can change your preference at any time by clicking "Cookie Settings" in the footer of any page.
  • Global Privacy Control (GPC): If your browser sends a GPC signal, analytics cookies are automatically disabled without requiring further action from you.
  • Browser settings: Most browsers allow you to block or delete cookies. Note that blocking essential cookies may prevent our services from functioning correctly.

7. Local Storage in Blankitt Draw

Blankitt Draw uses your browser's localStorage to store diagram data locally. This data never leaves your device unless you choose to use cloud save. Clearing your browser's local storage will delete any locally saved diagrams that have not been saved to the cloud.

8. Changes to This Policy

We may update this Cookie Policy from time to time. Changes will be reflected in the "last updated" date at the top of this page. Material changes may prompt a new consent request via the cookie banner.
