How CertNurse handles beta user data.

Information We Collect

• Your Google sign-in information, including your name, email address, and account identifier. CertNurse does not receive your Google password.
• Your practice activity: questions and versions attempted, selected answers, correctness, skips, answer timing, and saved quizzes and practice. We use this activity to show your topic progress and estimates.
• Your saved flashcards and review activity, including card versions, ratings, review times, and scheduling changes.
• Optional extra study activity: when questions, explanations, and flashcards are visible, approximate visible and recently active time, answer-option changes, card reveals, and request loading times. These records include content versions, small/medium/large screen size, and browser or installed-app display mode.
• Question ratings, optional comments, issue reports, account-deletion requests, and feedback you send to support. Question feedback includes the exact question version and practice context. We keep rating changes, private review notes, and replies so we can investigate and improve the content. Removing a rating removes its current vote; its earlier changes remain in this private history.
• Technical information needed to operate the service, including your sign-in status and security logs handled by our providers. This browser stores your sign-in session, theme, practice preferences, and answers waiting to save online.

How We Use Information

• To save your practice progress across sessions.
• To show topic progress, practice-based estimates, and suggestions for what to study next.
• To investigate question reports, bugs, and beta feedback.
• To assess question and answer-option quality, improve study suggestions and flashcard scheduling, and evaluate practice estimates. We may keep the practice evidence returned at the time so later analysis does not replace an earlier estimate with newer information.
• To protect and improve the platform.

What We Do Not Do

CertNurse does not sell beta user practice data. CertNurse does not claim to issue licenses, certifications, accredited education, or official exam content.

Extra study records do not contain typed keystrokes, screenshots, browsing history, advertising identifiers, or precise location. Viewing time does not prove attention or learning.

Extra Study Activity

You can turn off extra study activity in Profile under “Help improve CertNurse.” This account setting stops new optional observations and practice-evidence snapshots. Your submitted answers, saved progress, flashcard reviews, and feedback you explicitly send still work. Turning the setting off does not erase existing records; resetting progress removes the extra study history and snapshots along with your learning history, but keeps support messages, question ratings, and their history. Account deletion removes the account-linked records.

Optional events are sent in small batches. A temporary queue in this tab can retry after a connection problem or reload, for up to 24 hours. It is limited to 200 events and is cleared when you sign out or turn collection off on this browser. Closing the tab can discard unsent events. These observations may be incomplete; they are not a recording of everything you do.

Service Providers

The hosted beta uses Google for sign-in, Supabase for accounts and saved practice, and Cloudflare to deliver the website.

When you subscribe, Stripe processes payment details and manages recurring payments. CertNurse stores billing identifiers, subscription status, access dates, and checkout records; it does not store your full card number or security code. We share your account email with Stripe to set up billing.

Stripe collects your billing and home address during checkout to process payments, establish the service location, and help determine tax obligations. These addresses are kept in Stripe rather than your study history. Authorized staff can access billing records to resolve payment or tax issues.

Incoming support emails are routed through Cloudflare and received in Gmail. Resend sends account emails and, when enabled, support replies to your account email.

Support alert emails link staff to the private inbox without including your message. These services also process technical and security information under their own policies.

Homepage Sample Questions

We may randomly vary the sample question in each subject to learn which examples help visitors decide to join. When this measurement is enabled, a random identifier in your browser connects the questions you actually saw, whether you answered them, and whether you started sign-in.

If you create an account within seven days of that initial visit, we link the visit to the account once to count a completed signup. We compare questions you saw before creating the account; overall signup totals count the account only once. Returning sign-ins do not count as new accounts.

This optional measurement does not store your sample answer choices or correctness.

If you follow a CertNurse ad link, we may also record the campaign name with that visit. Our private report counts how many visitors create an account, start a trial, or make a first membership payment. We use our own billing records for these counts. We do not send your signup, payment, or study activity to the ad platform. The sample measurement choice below applies to this too.

Separately, demo questions keep your first answers in this browser’s local storage for 24 hours after your last answer. After that, the answers are no longer used and a new demo replaces them when you return. Account progress does not expire with the demo.

If you choose to save TEAS trial answers after signing in, we check them and add them to that account’s practice history and topic progress. We remove the browser’s answer copy after saving. Other product demos let you save selected flashcards after signing in; their sample answers are not added to account scores.

A progress reset removes the saved answers; a small account-linked save receipt prevents an old request from restoring them. Account deletion removes that receipt too.

Turning off sample measurement does not turn off this progress-saving feature.

We do not add advertising trackers or collect your IP address, browsing history, name, or email in these experiment records. Hosting and security logs are separate, as described above.

Visits older than 30 days are removed when the experiment next processes a visit, signup, or results request; deleting a linked account also removes its visit record.

Your Choices

We keep invitation redemptions and access dates to manage membership. A protected hash derived from your email records whether you have already used a free subscription trial. This eligibility marker remains after account deletion to prevent repeat trials; it contains no practice history or plain-text email. Stripe may retain payment records under its own policies. Resetting progress does not reset your subscription, invitation access, or trial eligibility.

You can reset your learning history or request account deletion from your profile. Resetting progress keeps your account and support requests. See the Data Deletion page for the process. For privacy questions or help accessing your account, email support@certnurse.com.
