Cookie Policy

Last updated: May 13, 2025

1. What Are Cookies?

Cookies are small text files stored on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work, or work more efficiently, and to provide information to website owners.

This website uses browser localStorage — a similar technology — rather than traditional cookies, to remember your preferences. The key distinction is that localStorage data never leaves your device and is not transmitted to our servers.

2. How We Use Cookies and localStorage

We use only one preference entry in your browser's localStorage:

This entry is strictly necessary for the cookie banner to function correctly and does not track your activity or share any data with third parties.

3. Third-Party Cookies

Some pages on this website embed content from third-party services. These services may set their own cookies, over which we have no control:

  • Lu.ma — The Events page embeds a Lu.ma calendar. Lu.ma may set cookies to track usage of their embedded widget.
  • PayPal — The Donate page includes a PayPal donation button. PayPal may set cookies when the payment flow is initiated.

We encourage you to review the privacy and cookie policies of these third-party providers for more information.

4. Managing Cookies

You can control and delete cookies or localStorage data through your browser settings. Note that deleting the tesf_cookie_consent key will cause the cookie banner to reappear on your next visit.

Instructions for managing cookies in popular browsers:

  • Google Chrome: Settings → Privacy and security → Cookies and other site data
  • Mozilla Firefox: Options → Privacy & Security → Cookies and Site Data
  • Safari: Preferences → Privacy → Manage Website Data
  • Microsoft Edge: Settings → Cookies and site permissions → Cookies and site data

5. Your Consent

By clicking "Accept" on our cookie consent banner, you consent to the use of the localStorage entry described above and to the possible setting of third-party cookies by the embedded services on our site.

If you click "Decline," we will store only the tesf_cookie_consent key with a value of "declined" so that we do not show you the banner again.

6. Changes to This Policy

We may update this Cookie Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page.
