How This Site Uses Cookies and Similar Technologies
Classic Science Fiction Archive uses cookies, local storage, and similar technologies to help the catalogue function reliably, to remember your preferences where you set them, and—only where you have consented—to understand how readers discover and use the collection. This policy explains what each type of storage does and how you can control it.
Essential Storage
Certain cookies and local storage items are necessary for the site to work. These may include a session cookie that keeps your browsing session secure, a cookie that remembers whether you dismissed a notice about the public-domain status of a work, or local storage that saves your reading progress on a long page. These essential technologies do not track you across other sites and are not used for advertising. If you disable all cookies, some parts of the catalogue—such as remembering your category filter—may not function as intended.
Preference Storage
If you choose a setting such as text size, display mode, or language, the site may store that choice in a cookie or in local storage so that it persists when you return. This storage is entirely under your control: you can clear it at any time through your browser settings, and the site will continue to work with default values.
Analytics Where Enabled
Where you have consented, the site may use a privacy-respecting analytics service (such as a self-hosted or anonymised tool) to collect aggregated, non-identifying information about page visits, referring sites, and the popularity of individual works. This data helps the catalogue project understand which catalogue entries—like Queen of the Martian Catacombs or Lord of a Thousand Suns—are of most interest to readers. No personal data is collected, and no analytics cookies are set without your consent. You can withdraw consent at any time using the consent controls available on the site.
Advertising Where Displayed
Some pages may display advertisements provided by Google AdSense or other Google advertising services. Where ads are shown, Google may use cookies and web beacons to serve ads based on your visits to this and other websites. These cookies allow Google and its partners to serve personalised or contextual advertisements. The use of such advertising technologies is conditional: if no ads are displayed on a given page, no advertising cookies are used. You can learn more about Google’s advertising practices and opt out of personalised advertising by visiting Google’s Ads Settings page.
First-Party and Third-Party Cookies
First-party cookies are set by this site and are used only for the purposes described above. Third-party cookies may be set by Google (for advertising or analytics where enabled) or by embedded content from other services. This site does not control the cookies set by third parties, and you should consult the relevant provider’s privacy policy for details.
Session and Persistent Storage
Session cookies and session storage are temporary and are deleted when you close your browser. Persistent cookies and local storage remain on your device for a variable period, depending on the technology used and your browser settings. The site does not set fixed expiry durations for persistent storage; instead, it uses durations that are reasonable for the purpose (e.g., a preference cookie may last for one year, while an analytics identifier may last for two years). You can clear all persistent storage at any time through your browser’s privacy settings.
Local Storage
In addition to cookies, the site may use browser local storage to remember your reading position on long texts or to cache catalogue data for faster loading. This data stays on your device and is not automatically transmitted to any server. You can clear local storage using your browser’s developer tools or privacy settings.
Your Consent Choices
When you first visit the site, a consent notice asks you to accept or decline optional cookies (analytics and advertising). You can change your choice at any time by clicking the “Cookie Settings” link in the footer of any page. Withdrawing consent for optional cookies will not affect the essential functions of the catalogue.
Browser Controls
Most web browsers allow you to control cookies and local storage through their settings. You can typically block all cookies, delete existing cookies and storage, or set preferences for individual sites. Please note that disabling essential cookies may affect the site’s performance and your ability to use certain features.
Practical Effects of Disabling Storage
If you disable all cookies and local storage, the site will still load and you can read public-domain works such as Martian Nightmare or The Dancers. However, you may need to re-enter preferences on each visit, your reading progress on long pages may not be saved, and any consent choices you make will not be remembered, causing the consent notice to appear on every page load.
Updates to This Policy
This Cookie Policy may be updated to reflect changes in technology, legal requirements, or the way the catalogue operates. Any changes will be posted on this page, and if they significantly affect your rights, you will be notified via a notice on the site.
