Information we collect
Slide Collection is a browse-only catalogue. We do not ask you to create an account, and we do not request personal information to use the site. Like most websites, our servers may record standard technical request data — such as your IP address, browser type, referring page, and the time of each request — in temporary log files used to operate the service, diagnose problems, and protect against abuse.
Cookies and local storage
Slide Collection uses only the cookies and local storage strictly necessary for the site to function, such as remembering basic display preferences. We do not set our own advertising or cross-site tracking cookies. If we introduce third-party services that set cookies, any consent those services require will be handled through their own standard consent mechanism.
Third-party services
Detail pages link out to, and may embed viewers from, the upstream archives we catalogue — including the Internet Archive, Wikimedia Commons, OpenStax, and MIT Open Learning Library. When you follow a link to or load content from one of those sources, that third party may collect data under its own privacy policy, which we do not control. We may also use privacy-respecting analytics and standard hosting or content-delivery providers to keep the site running.
How we use information
Any technical data we hold is used solely to operate and improve Slide Collection: serving pages, measuring aggregate traffic, keeping the catalogue available, and preventing abuse. We do not sell visitor data, and we do not build advertising profiles from your visits.
Data retention
Server logs are kept only for as long as they are useful for operations and security, and are then discarded or anonymized. We do not maintain long-term personal records about individual visitors.
Children's privacy
Slide Collection is an educational reference catalogue intended for a general audience. We do not knowingly collect personal information from children.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected on this page. Continued use of the site after an update constitutes acceptance of the revised policy.
