Privacy Policy

Last updated: October 20, 2026

This policy explains what personal data MyQuantPartner, LLC collects when you use myquantpartner.com (the "Service"), why we collect it, how long we keep it, and what rights you have under the General Data Protection Regulation (GDPR) and other applicable data protection laws.

1. Who we are

The data controller for the Service is MyQuantPartner, LLC, a Delaware limited liability company (Delaware File Number 10713755), registered office at 131 Continental Dr, Suite 305, Newark, DE 19713, USA ("MyQuantPartner", "we", "us", "our"). Full company details are on our Legal Notice page.

For any question, request, or complaint relating to your personal data, contact us at [email protected]. We respond within one month, as required by Article 12(3) of the GDPR.

EU representative

MyQuantPartner, LLC is not established in the European Union and offers the Service to people located in the EU. Under Article 27 of the GDPR, we have designated the following representative in the EU:

Edward Bauduin
26 Avenue du Pavé Neuf, 93160, Noisy Le Grand
[email protected]

You may contact our representative instead of, or in addition to, us on any matter relating to the processing of your personal data.

2. What we collect

We only collect the data we need to provide the Service:

  • Account information: email address, hashed password (we never see your password in plain text), optional first and last name, and an optional avatar URL if you sign in with a third-party identity provider.
  • Public profile and leaderboard information: your handle, display name, avatar, and the progress you earn on the Service (experience points, aura, badges, rank, streaks, and solve counts).
  • Practice and interview activity: the written answers you submit, the voice transcripts of mock interviews you record, the scores and feedback produced by our automated grading system, and session metadata (topic, difficulty, company filter, duration).
  • Billing data: your subscription tier, billing period, and the identifier our payment processor associates with you. We never receive or store full payment card numbers. Those are handled entirely by our payment processor.
  • Communication preferences: whether you have agreed to receive promotional emails, and when.
  • Technical data: IP address, browser and device information visible from standard HTTP requests, and authentication cookies (described in Section 9). We use these to keep your account secure and the Service reliable.

3. Why we process it

For each purpose below we identify the legal basis under Article 6 of the GDPR.

  • To provide and maintain your account. Legal basis: performance of a contract (Art 6(1)(b)).
  • To grade your practice and interview submissions and build your performance history. Legal basis: performance of a contract (Art 6(1)(b)).
  • To display your public profile and leaderboard ranking to other users. Legal basis: our legitimate interests, and those of other users, in operating a competitive ranking that motivates practice (Art 6(1)(f)). Only the information listed under "Public profile and leaderboard information" is shown. You can object at any time by switching off Show on leaderboard in your profile settings (see Terms of Service, Section 15).
  • To process payments and manage subscriptions. Legal basis: performance of a contract (Art 6(1)(b)) and compliance with legal obligations for tax and accounting records (Art 6(1)(c)).
  • To keep the Service secure and detect abuse, including manipulation of the automated grader. Legal basis: our legitimate interests in protecting the Service and the integrity of other users' progress data (Art 6(1)(f)).
  • To send service-related emails (sign-in confirmation, password reset, billing receipts). Legal basis: performance of a contract (Art 6(1)(b)).
  • To send promotional emails. Legal basis: your consent, given at sign-up or in your account settings (Art 6(1)(a)). Where applicable law allows us to email existing users about similar features of the Service without prior consent, we rely on our legitimate interests (Art 6(1)(f)). Every promotional email contains an unsubscribe link, and you can opt out at any time in your account settings.

We do not use your personal data for advertising or marketing profiling, and we do not sell your personal data to anyone.

4. Automated decision-making and AI grading

Our practice and mock interview features use automated systems (large language models) to score your answers and generate written feedback. Under Articles 13(2)(f) and 22 of the GDPR, you have the right to know this is happening and to understand the general logic involved.

When you submit an answer, an AI model compares it against the canonical solution stored in our problem bank and produces a numeric score plus written feedback. Scores estimate correctness and clarity. They are used only within the Service, to track your progress and to compute leaderboard rankings. We do not share your scores with employers, schools, or any third party for hiring or admission decisions.

Decisions to suspend or ban an account, including for manipulation of the grader (Terms of Service, Section 18), are never taken solely by automated means. A person reviews the case before any such action. You can contest a score or an account decision by writing to [email protected].

5. Who we share data with

We share the minimum amount of data needed with the following categories of recipients:

  • Cloud hosting and infrastructure providers who run the servers the Service is deployed on. Our hosting provider is named on our Legal Notice page.
  • Database and authentication providers who store your account and activity data on our behalf.
  • Payment processing providers who handle subscription billing and store payment card data on their own infrastructure.
  • Voice transcription service providers who convert the audio of your mock interviews to text in real time.
  • AI and large language model providers who grade your answers and generate the interviewer's spoken responses.
  • Email delivery providers who send service-related and, where you have agreed, promotional emails.
  • Third-party identity providers such as Google, only if you choose to sign in with them. If you sign in with email and password, no third-party identity provider receives your data.
  • Other users of the Service, who can see your public profile and leaderboard information while Show on leaderboard is on.

A current list of named processors is available on request at [email protected]. All processors are bound by written agreements that include the protections required by Article 28 of the GDPR.

6. International data transfers

MyQuantPartner, LLC is based in the United States. When you use the Service from the European Economic Area (EEA), you provide your personal data directly to us, and the GDPR applies to our processing under Article 3(2).

When we, or our processors, transfer personal data onward to recipients located in countries outside the EEA, each transfer relies on one of the following safeguards:

  • an adequacy decision of the European Commission, including the EU-US Data Privacy Framework for recipients certified under it; or
  • the European Commission's Standard Contractual Clauses (SCCs), which require the recipient to apply protections equivalent to the GDPR.

You can request a copy of the relevant safeguards at [email protected].

7. How long we keep your data

  • Account, profile, practice, and interview data: kept while your account is active. When you delete your account from your account settings, it is erased immediately. When you ask us to delete it by email, we erase it within one month of your request (Terms of Service, Section 16). Residual copies in backups are overwritten on our normal backup rotation.
  • Billing and accounting records: kept for as long as applicable tax and accounting law requires, even after your account is deleted (Art 17(3)(b) GDPR).
  • Server logs: kept for up to twelve months for security and debugging, then deleted or anonymised.
  • Promotional email consent records: kept for as long as your consent is active and, after withdrawal, for as long as needed to prove that consent was obtained.

8. Your rights

Under the GDPR you have the right to:

  • Access a copy of the personal data we hold about you (Art 15).
  • Rectify data that is inaccurate or incomplete (Art 16).
  • Erase your data, also called "the right to be forgotten" (Art 17).
  • Restrict how we process your data in certain situations (Art 18).
  • Receive your data in a portable format so you can move it to another service (Art 20).
  • Object to processing that relies on our legitimate interests, including the leaderboard and security processing (Art 21).
  • Object at any time to processing for direct marketing (Art 21(2)).
  • Withdraw consent at any time, for any processing that relies on consent, without affecting the lawfulness of processing before withdrawal (Art 7(3)).
  • Obtain human review of, express your point of view on, and contest a decision based on automated processing (Art 22(3)).

To delete your account, use Account preferences in your account settings, or email [email protected] from the address the account is registered to (Terms of Service, Section 16). For every other request, email [email protected]. We respond within one month. Exercising your rights is free unless a request is manifestly unfounded or excessive (Art 12(5)).

You also have the right to lodge a complaint with a supervisory authority, in particular in the EU member state where you live, work, or where the alleged infringement took place (Art 77). In France, this is the Commission Nationale de l'Informatique et des Libertés (CNIL).

9. Cookies

We only use cookies that are strictly necessary to operate the Service: to keep you signed in and to protect against forgery of authenticated requests. These cookies are exempt from prior consent under EU law, so we do not display a cookie banner.

Our payment processor may set its own cookies to detect fraud during checkout. These are also strictly necessary for the payment to work.

We do not use cookies for analytics, advertising, or marketing profiling. If we add such cookies in the future, we will ask for your explicit consent through a cookie banner before placing them, and you will be able to refuse or change your choice at any time.

10. Security

We protect your data with industry-standard technical and organisational measures, including encrypted connections (HTTPS), password hashing, secure session cookies that JavaScript on the page cannot read, and access controls on our backend systems. No system is perfectly secure, and we cannot guarantee absolute protection against every possible attack, but we work continuously to minimise risk.

If we discover a personal data breach likely to result in a risk to your rights and freedoms, we will notify the competent supervisory authority within 72 hours and, where the risk is high, inform affected users directly, as required by Articles 33 and 34 of the GDPR.

11. Children

The Service is not available to anyone under 16. Users aged 16 or older who have not reached the age of majority in their country need the consent of a parent or legal guardian (Terms of Service, Section 2). We do not knowingly collect personal data from children under 16. If you believe a child under 16 has provided us with personal data, contact us and we will delete it.

12. Changes to this policy

We may update this policy to reflect changes in the Service, the law, or our processors. The "Last updated" date at the top of this page changes whenever the policy is revised. For material changes that affect your rights, we will notify signed-in users by email or through an in-app notice before the change takes effect.
