What are cookies?

Cookies are small text files stored on your device by your web browser when you visit a website. They allow the site to remember information about your visit, such as whether you are signed in. Some cookies are essential for the site to work; others are used for analytics or advertising.

BERTlinker uses only essential cookies. We have no analytics, advertising, or third-party tracking cookies whatsoever.

localStorage data never leaves your browser and is not sent to our servers.

Third-party cookies

BERTlinker does not set any third-party cookies. We do not use Google Analytics, Facebook Pixel, or any advertising or tracking service. Payment processing is handled by Stripe on their own domain, so any cookies Stripe sets are governed by Stripe's Privacy Policy.

Managing cookies

Because all our cookies are essential for the site to function, disabling them may prevent you from signing in or using parts of the service. You can clear cookies at any time through your browser settings.
