How We Use Storage on Your Device
When you visit Historical Physics Library (eatsb.com), small text files known as cookies may be placed on your device, along with similar technologies such as local storage. This page explains the types of storage we use, their purpose, and how you can control them.
Essential Cookies
Certain cookies are necessary for the catalogue to function. These include session cookies that remember your current visit so you can navigate between pages without re-entering information, and persistent cookies that store your cookie consent preferences. Without these, the site may not operate correctly. Essential cookies do not require your prior consent.
Preference Cookies
Where enabled, we use cookies to remember your chosen display settings, such as text size or reading mode. These are first-party cookies and are only set if you interact with a preference control. They are not used for tracking.
Analytics Cookies
If analytics are enabled on your visit, we may use a first-party analytics service to collect anonymous aggregate data about how readers use the catalogue — for example, which editions are most often viewed. These cookies help us understand which works are of interest and improve the browsing experience. No personal identifying information is collected.
Advertising Cookies
On certain pages where advertisements are displayed, we may use Google advertising technologies, including cookies, to serve relevant ads. These cookies may be set by Google or its partners, and they allow ad networks to recognise your device across sites. This helps limit how often you see the same ad and measure the effectiveness of campaigns. We do not control which specific third-party cookies are set by Google’s ad services. You can learn more about Google’s use of data at Google’s Privacy & Terms site.
Third-Party Cookies
Some pages may embed content from external platforms (such as video players or social sharing widgets). Those services may set their own cookies. We do not control those cookies and recommend reviewing the privacy policies of those services.
Session and Persistent Cookies
Cookies may be session-based (deleted when you close your browser) or persistent (stored for a period set by the cookie). The exact duration varies by purpose and provider. Persistent cookies from analytics or advertising may remain for up to a few months, after which they are automatically removed or renewed.
Local Storage
In addition to cookies, we may use local storage in your browser to cache catalogue data for faster loading. This data stays on your device and is not automatically transmitted to us.
Your Choices
Consent for Optional Cookies
When you first visit the site, a banner asks for your consent to set non-essential cookies (analytics and advertising). You may accept all, decline all, or customise your preferences. Your choice is recorded in a persistent cookie so you are not asked again for a reasonable period.
Withdrawing Consent
You can change your preferences at any time by clicking the “Cookie Settings” link available in the footer of every page. Withdrawal does not affect the lawfulness of processing based on consent before its withdrawal.
Browser Controls
Most browsers allow you to view, block, or delete cookies through their settings. You can also enable “Do Not Track” or similar signals. Note that disabling all cookies may affect the functionality of the catalogue, including the ability to save reading preferences or log in to any future account features.
Practical Effects of Disabling Storage
If you block essential cookies, some parts of the site may become inaccessible. Blocking analytics cookies does not affect your reading experience but prevents us from improving the catalogue based on usage patterns. Blocking advertising cookies may result in less relevant ads but does not stop ads from appearing.
Updates
This policy may be updated to reflect changes in technology or regulation. Any material changes will be notified via the site. We encourage you to review this page periodically.
If you have questions about our use of cookies, you can contact our Managing Editor, Charles Fitzgerald, at editor@eatsb.com.
