What personal data we collect and why we collect it

Cloud Registration

When you register for Blue Twilight Cloud, we collect your name and e-mail address so we may communicate service issues and contact you about your Cloud galleries.


When you leave comments on this website, we collect the data shown in the comments form, and also your IP address and browser user agent string to help spam detection.

An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy is available here: https://automattic.com/privacy/. After approval of your comment, your profile picture is visible to the public in the context of your comment.


If you leave a comment on our site you may opt-in to saving your name, email address and website in cookies. These are for your convenience so that you do not have to fill in your details again when you leave another comment. These cookies will last for one year.

If you visit our login page, we will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

When you log in, we will also set up several cookies to save your login information and your screen display choices. Login cookies last for two days, and screen options cookies last for a year. If you select “Remember Me”, your login will persist for two weeks. If you log out of your account, the login cookies will be removed.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.


To ensure you are getting the optimal experience when using this website, we monitor your browsing habits – for example the pages you have visited and links you click on.

This information is anonymised, aggregated and cannot be tracked back to an individual user.

You can opt-out of analytics using the form below:

Who we share your data with

Your data is held on infrastructure (servers and storage devices) owned and operated by Memset Hosting Ltd. The data environment is Memset’s Dunsfold data centre in Surrey, UK.

Backups are taken regularly and uploaded to Backblaze’s data-centre in Sacramento in the United States. The data is encrypted before it leaves the UK and cannot be decrypted by Backblaze.

How long we retain your data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue.

For users that register on our website (if any), we also store the personal information they provide in their user profile. All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

What rights you have over your data

If you have an account on this site, or have left comments, you can request to receive an exported file of the personal data we hold about you, including any data you have provided to us. You can also request that we erase any personal data we hold about you. This does not include any data we are obliged to keep for administrative, legal, or security purposes.

Additional information

How we protect your data

Our servers are protected by a combination of hardware and software firewalls. Administration ports (for example, SSH) are restricted to a whitelist of IP addresses.

Password authentication is disabled for remote connections to the servers and public key authentication is used instead.

Data breach notification

If we suspect a data breach has occurred, we will fully investigate what data may have been compromised and notify affected customers by e-mail within 72 hours of being made aware of the suspected breach occurring.
