Cookies

If you leave a comment, you may opt-in to saving your name, email address, and website in cookies for convenience. These cookies last for one year.

If you visit our login page, a temporary cookie determines if your browser accepts cookies. It contains no personal data and is discarded when you close your browser.

When you log in, cookies are set to save your login information and display preferences. Login cookies last for two days; display option cookies last for one year. Selecting “Remember Me” extends login persistence to two weeks. Logging out removes login cookies.

If you edit or publish an article, a cookie is saved in your browser with the post ID of the article you edited. It expires after one day.

Embedded Content from Other Websites

Articles on this site may include embedded content (e.g., videos, images, or articles). Embedded content from other websites behaves exactly as if you visited those sites directly.
These websites may collect data, use cookies, embed additional third-party tracking, and monitor your interaction with that content — especially if you have an account and are logged in to those websites.

Analytics and Performance Tracking

We may use website analytics tools (such as Google Analytics) to better understand visitor behavior, improve user experience, and monitor website performance.
These tools collect non-identifiable information such as pages visited, time on site, browser type, and general geographic location.
You can opt out of Google Analytics tracking using your browser settings or Google’s opt-out tools.

Who We Share Your Data With

If you request a password reset, your IP address will be included in the reset email.
We may also share limited data with service providers who assist with website hosting, maintenance, or email communication — but only to the extent necessary for them to perform their services.

How Long We Retain Your Data

If you leave a comment, the comment and its metadata are retained indefinitely to recognize and approve follow-up comments automatically.
For registered users (if any), we store personal information in their user profile. All users can view, edit, or delete their personal information at any time (except the username). Website administrators can also view and edit that information.
Form submissions are retained only as long as needed to fulfill your request or maintain business records.

Your Rights Over Your Data

If you have an account on this site or have left comments or form submissions, you can request an exported file of the personal data we hold about you, including any information you’ve provided.
You can also request that we erase any personal data we hold about you. This does not include data retained for administrative, legal, or security purposes.
Requests can be submitted to info@313subsurface.com.

Where Your Data Is Sent

Visitor comments and form submissions may be checked through an automated spam detection or filtering service.
