This is the general policy for dotCreds web practice pages. Last updated: April 12, 2026.
Use the site as a guest, or optionally add email later to sync progress. We use privacy-friendly analytics, AdSense ads, and local storage for daily practice progress.
Daily question answers, score counts, and cert-page progress can be stored in your browser local storage. If you choose email progress sync, the same progress can be associated with your email address so it can move across browsers.
If you request a magic link, we store the email address and a temporary hashed sign-in token. The raw token is sent to you and is not stored as plain text.
We use Plausible Analytics to understand page views, catalog clicks, and practice-page usage without building invasive personal profiles.
dotCreds pages may show Google AdSense ads. Google may use cookies or similar technologies to serve, measure, and improve ads according to Google's policies.
We use local progress data to keep your daily practice state from resetting if you refresh the page or come back later on the same device.
We use email only to send sign-in links and connect your practice progress to your account if you opt in. We do not require an account for guest practice.
We use aggregate traffic and practice signals to decide which certification pages should get more content, premium web features, or a mobile app.
If you have a privacy or support question, use the support page or contact the dotCreds owner through the published app support channels.
