Privacy Policy

Effective: 2026-08-28 · Back to Summit

1. Introduction

This Privacy Policy explains how Christensen Harker LLC ("Company," "we," "us," or "our") collects, uses, shares, and protects personal information when you use Summit — our AI-assisted learning platform — and the associated websites and applications at summitproficiency.com (the "Service"). It is a companion to our Terms of Service. Capitalized terms not defined here have the meaning given in the Terms.

This policy covers Learners, Instructors, and visitors.

2. Information We Collect

2.1 Information you provide. Account details (such as your name and email address); Source Material and other User Content you upload or enter; your messages, answers, and productions during sessions; support and other communications with us; and information you submit to join a waitlist or express interest.

2.2 Payment information. When you buy Credits, our payment processor (Stripe) collects and processes your payment details. We receive limited transaction data (such as confirmation, amount, and a payment identifier) but do not collect or store full payment-card numbers.

2.3 Information collected automatically. Usage and session data (sessions started, messages, scores, progress, and token/credit usage), and technical data (device and browser type, IP address, timestamps, and log data). We use cookies and similar technologies as described in Section 10.

2.4 Information from others. We may receive information from authentication and infrastructure providers that help us run the Service. We do not currently receive class rosters or enrollment lists from any school or institution.

2.5 Sensitive and student information. Your User Content may include information about learning or performance. Please do not upload sensitive personal information you are not authorized to share, and do not upload another person's information without the necessary rights and consents.

3. How We Use Information

We use personal information to: (a) provide, operate, and secure the Service, including generating Output and running sessions, probes, drills, scoring, and reports; (b) personalize your experience — for example, maintaining a Learner "memory" so future sessions build on your prior work, where you have consented as described in Section 6; (c) process payments, Credits, and refunds, and prevent fraud and abuse; (d) communicate with you about your account, changes, support, and (where permitted) updates you can opt out of; (e) understand usage and improve and develop the Service and its teaching methods, including through research using de-identified or aggregated data, where you have consented as described in Section 6; (f) maintain safety and security, enforce our Terms, and comply with legal obligations.

4. How AI Processing Works

4.1 Model provider. The Service uses Anthropic's Claude models to generate Output. To produce a response, we send the tutoring conversation and the study material provided for that session to Anthropic; Anthropic processes it and returns the response to us.

4.2 What we do not send. We do not send your name, email address, or account identifiers to Anthropic. Those are used only on our own systems — for sign-in and to check your consent settings — and never as part of a prompt. The only way personal information reaches the model is if it appears in the conversation or in uploaded study material: for example, if you type your name, or an uploaded file's contents or file name contain identifying information.

4.3 No training; retention. Under Anthropic's commercial API terms, Anthropic does not use data submitted through the API to train its models without our permission, and does not sell it. Anthropic does retain what we send it for a limited period under its own terms, for abuse-prevention and legal purposes. We do not have a Zero Data Retention arrangement with Anthropic, so we cannot tell you that your conversation is discarded the moment a response is returned.

4.4 Automated processing. The Service uses automated systems to generate teaching content, scores, and reports. These are learning aids and estimates, not decisions that produce legal or similarly significant effects about you; see the Terms for their limits.

5. How We Share Information

We share personal information only as described here. We do not sell your personal information.

5.1 Service providers (subprocessors). AI processing (Anthropic); payment processing (Stripe); database, authentication, and hosting (Supabase); application hosting and compute (Render); and transactional email (Resend). We do not use any third-party analytics or advertising provider. A current list is available on request.

5.2 Instructors. (REWRITTEN 2026-08-31 — supersedes the 2026-08-27 version, which described a per-result choice the Service no longer offers.) If you complete a probe a professor published, we share your name and that probe's results with him. What he sees is set out in full in Section 7. It is governed by this policy, not by any arrangement between us and your school — we have no agreement with your institution, receive no roster from it, and act on no instruction from it. Your choice is whether to use Summit for the class at all (see 7.4).

5.3 Legal, safety, and rights. We may disclose information if required by law or legal process, or where we believe in good faith it is necessary to protect the rights, safety, or property of users, the public, or the Company, or to enforce our Terms.

5.4 Business transfers. If we are involved in a merger, acquisition, financing, or sale of assets, information may be transferred as part of that transaction, subject to this policy.

5.5 Aggregated / de-identified data. We may create and share data that no longer identifies you, such as aggregate usage statistics or research findings.

6. Your Consent Choices: Memory and Research

6.1 Learner memory. With your consent, we retain a personalized "memory" of your prior sessions so the Service can build on what you have already done. You can decline or turn this off; doing so may reduce personalization.

6.2 Research and improvement. With your consent, we may use your data — preferring de-identified or aggregated forms — to research and improve the Service and its teaching methods. You can withdraw this consent for future use.

6.3 Managing consent. You can review and change these choices in your account settings or by contacting us. Withdrawing consent does not affect processing already carried out.

7. What Your Professor Can See

(REWRITTEN 2026-08-31. Supersedes the 2026-08-27 version, which described a per-result sharing choice that no longer exists. This section is the one students actually need, and it must match the product exactly.)

7.1 If you complete a probe for a class, your professor sees your results. This is how Summit works, it is the same for everyone, and we tell you on the start screen before your first question rather than asking you later. When you complete a probe a professor published, he sees the name you gave and the specific gaps your probe found.

There is no per-result choice to make, no sharing level to set, and no anonymous option. We removed them because almost nobody used them and their real effect was to hide participation rather than protect anyone — and because a diagnostic the professor cannot see cannot do the job he adopted it for.

7.2 What he does NOT see. Your conversation transcript, your email address, anything you did in a different class, or anything from a paid Summit session you started on your own. He sees results from probes he published, and nothing else.

7.3 Your professor sets nothing. There is no control anywhere in Summit that lets an instructor choose what he can see about you, raise it, or single you out. What he sees is fixed by us, disclosed here, and identical for every student.

7.4 If you would rather he did not see your results, do not use Summit for the class. That is the real choice, and it is why it belongs before you start rather than after. Where a professor offers credit for completing a probe, he must also offer an alternative assignment of comparable effort and equal credit — so declining costs you nothing. Ask him for it.

We will not pretend this is reversible. Once your results have reached your professor we cannot un-tell him, and we would rather say so plainly than offer a retraction that does not really retract. Deleting your account stops future sharing and removes your data from Summit (see section 8); it does not reach what he has already seen.

7.5 We never receive a roster. Your school does not give us a class list, and we do not connect your account to one. The name your professor sees is the name you gave us. If it is not the name he knows you by, he may not be able to match you — which also means a name you would rather not use is a name we never had.

7.3 Class misconceptions — what "aggregate" actually shows, and what it never shows. At the aggregate level and above, your professor sees a map of the mistaken ideas his class holds. Two rules govern it, and neither is ours to relax quietly:

• Only a short neutral label crosses — never your words. The map says something like

"treats a pointer as the value it points to." It never carries anything you typed, never a quotation, never a sentence written to you about your own answer. What you wrote stays between you and Summit.

• A misconception is only shown once enough of the class shares it. At least two

students must hold an idea before it appears at all, and at least five students must have completed the probe and opted in before your professor sees any of the map. Below that, he is told the class is too small and shown nothing. This exists so that in a small class "someone believes X" cannot become "you believe X."

7.6 Sessions from before 2026-08-31 keep the terms they were taken under. If you used Summit while the older sharing choice existed, whatever you chose then still governs that session. This change is not applied backwards, and a session you kept private stays private.

7.7 Required, graded, or roster-linked use. We do not offer required or graded use, or a roster-linked dashboard identifying individual students, unless the institution and the Company have entered a written agreement (such as a data processing and FERPA addendum) and completed the institution's required review. No such agreement is in place. Where one exists, and where applicable, we would act as the institution's service provider and "school official" under FERPA, using student personal information only to provide the Service and not for advertising.

8. Data Retention

We keep personal information for as long as your account is active and as needed to provide the Service. You can delete any individual probe yourself, from that probe's results screen, once it has finished. To delete a probe you did not finish, or your account and everything in it, email support@summitproficiency.com and we will do it for you. After you close your account or ask us to delete your data, we delete or de-identify it within 30 days, except where we must keep it to comply with law, resolve disputes, or enforce our agreements. Residual copies may persist in routine backups for up to 30 days before being overwritten. We may retain de-identified or aggregated data indefinitely.

9. Your Rights and Choices

9.1 General. You can access and update account information in the Service, and you can request access to, correction of, or deletion of your personal information, or a copy of it, by contacting us at support@summitproficiency.com. We will respond as required by applicable law and may need to verify your identity.

9.2 Marketing. You can opt out of promotional emails using the unsubscribe link or by contacting us. We will still send necessary account and transactional messages.

9.3 EU/UK users. If you are in the European Economic Area or the United Kingdom, you may have rights to access, rectify, erase, restrict, or object to processing, and to data portability, and to lodge a complaint with a supervisory authority. Where we rely on consent, you may withdraw it at any time. Our legal bases include performance of our contract with you, your consent, and our legitimate interests in operating and improving the Service.

9.4 California users. If you are a California resident, you may have rights to know, delete, and correct personal information, and to opt out of "sale" or "sharing" of personal information. We do not sell your personal information. You may exercise these rights using the contact details below, and we will not discriminate against you for doing so.

9.5 Do Not Track. The Service does not respond to browser "Do Not Track" signals, which are not yet standardized.

10. Cookies and Similar Technologies

We use no optional cookies, no tracking cookies, and no third-party analytics. There is nothing here to opt out of.

We use your browser's local storage to keep you signed in and to remember your preferences between visits. This is essential to the Service — it is how the Service knows it is still you — and it is not shared with anyone. We set a small number of functional cookies for the same purpose. You can clear both through your browser, but doing so will sign you out.

11. Children's Privacy

The Service is intended for users 18 and older, and for users 13–17 only with the consent and supervision of a parent, guardian, or authorized institution, as described in the Terms. We do not knowingly collect personal information from children under 13 without the consent required by law. If you believe a child under 13 has provided us personal information without the required consent, contact us and we will take appropriate steps to delete it.

12. Security

We use reasonable administrative, technical, and organizational measures designed to protect personal information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security. Please keep your account credentials confidential and notify us of any suspected unauthorized access.

13. International Users and Data Transfers

We operate in the United States, and we and our providers process and store information in the United States and potentially other countries. If you access the Service from outside the United States, you understand that your information will be transferred to and processed in the United States, where privacy laws may differ from those in your location. Where required, we use appropriate safeguards for such transfers.

14. Third-Party Links

The Service may link to third-party sites or services we do not control. This policy does not apply to them, and we are not responsible for their privacy practices.

15. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will take reasonable steps to notify you, such as posting the updated policy with a new effective date or notifying you through the Service. Your continued use of the Service after changes take effect means you accept the updated policy.
