Presidentl is operated by Keystone Dynamic. There is no account and no sign-up.
Your streak, record, guess distribution, today's progress and quiz difficulty are kept in your browser's local storage. This is not a cookie, is never sent to us, and we cannot read it. Clearing your browser data erases it permanently.
We use Vercel Web Analytics to count visits. It is cookieless, does not fingerprint you and does not track you across other sites. It records aggregate data such as page, referrer, country, browser and device type. We cannot identify you from it.
Presidentl is supported by advertising served through Google AdSense.
• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• You may opt out of personalised advertising by visiting Google Ads Settings.
• You may opt out of third-party vendors' use of cookies at aboutads.info/choices or optout.networkadvertising.org.
Google may use the DoubleClick cookie or similar identifiers, and ad networks may collect IP address, device identifiers and interaction data. We do not receive or control that data.
Advertising and analytics storage are denied by default and no personalised advertising cookie is set until you consent through a Google-certified consent management platform. You may change or withdraw consent at any time in that tool, and you have the right to access, correct, export or erase personal data and to complain to your supervisory authority. As we hold no account data, such requests are best directed to Google via the links above.
We do not sell personal information and receive no money for personal data. Advertising cookies set by Google may still count as "sharing" for cross-context behavioural advertising under the CCPA/CPRA; opt out via the links above or a Global Privacy Control signal, which we honour where transmitted.
Presidentl is not directed to children under 13 and we do not knowingly collect personal information from them.
Presidentl is provided free, for entertainment and education, with no warranty of any kind. We aim to be accurate about the historical record but do not guarantee it. Presidential portraits are public-domain works; biographical links point to Wikipedia, which carries its own terms and privacy policy. If a portrait is not bundled, the app may request it from Wikimedia.
If this policy changes materially, the date above changes. Questions: kstdyn@gmail.com.
