Privacy Policy

Effective June 13, 2026

SaturnPath(“we,” “us”) provides a personalized SAT study-planning tool. This policy explains what information we collect, how we use it, who we share it with, and the choices you have. By creating an account you agree to this policy. This service is intended for users in the United States.

Information we collect

  • Account information — your name, email address, and password (passwords are stored and verified by our authentication provider; we never see them in plain text).
  • Age & consent records — the birth year you provide at sign-up (used to confirm you meet our minimum age and to determine whether a parent/guardian acknowledgement is required), and a timestamp recording your acceptance of our Terms and this policy. We do not collect your full date of birth.
  • Study profile — your current and target SAT scores, test date, and study-time preferences.
  • Study activity — practice sessions you log (questions attempted/correct by topic), error-log notes you write, scores you enter, generated study tasks, and reminder/notification preferences including your timezone.
  • Usage & device data — aggregate, privacy-preserving analytics about page performance and visits, collected via Vercel Analytics and Vercel Speed Insights. These do not use advertising cookies and do not track you across other websites.

We do not store College Board SAT questions, passages, or answer choices. The app only records the numeric results and your own written notes.

How we use your information

  • To create and operate your account and generate your personalized study plan.
  • To compute analytics, topic mastery, and score predictions shown to you.
  • To send the reminder emails and in-app notifications you have enabled.
  • To confirm you meet our minimum-age requirement and comply with children’s and student privacy laws.
  • To maintain security, prevent abuse, and improve reliability and performance.

We do not sell or share your personal information, we do not use it for targeted advertising, and we do not build advertising profiles about you.

Cookies & analytics

We use a small amount of strictly necessary browser storage to keep you signed in and to remember your preferences (for example, your theme and whether you have dismissed our cookie notice). For product analytics we use Vercel Analytics and Vercel Speed Insights, which are designed to be privacy-preserving and do not use advertising or cross-site tracking cookies. Because we do not use advertising cookies, we do not show a blocking cookie consent gate; you can control non-essential storage through your browser settings.

Service providers

We share data only with vendors that process it on our behalf to run the service:

  • Supabase — authentication and database hosting (stores your account and study data).
  • Vercel — application hosting, plus Analytics and Speed Insights.
  • Resend — delivery of reminder emails (only if you enable email reminders).

Children’s privacy (COPPA) & student data

Our service is intended for students preparing for the SAT, who may be under 18. You must be at least 13 years old to create an account. We do not knowingly collect personal information from children under 13; we ask for your birth year at sign-up and block account creation if you are under 13. If you are under 18, we ask you to confirm that a parent or guardian has given permission for you to use the service. If we learn that we have collected information from a child under 13 without verifiable parental consent, we will delete it. Parents or guardians who believe their child under 13 has provided us information can contact us at saturnpathsupport@gmail.com.

We treat the information you enter as student data: we do not sell it, we do not use it for targeted advertising, and we do not create advertising or behavioral profiles for non- educational purposes. If you use this product through a school, the school may have additional rights and responsibilities under FERPA and applicable state student-privacy laws (such as California’s SOPIPA), and we will support the school’s lawful requests regarding its students’ data.

California privacy rights (CCPA/CPRA)

If you are a California resident, you have rights regarding your personal information. In the past 12 months we collect the categories described under “Information we collect” above (identifiers such as name and email, your age/consent records, and your study profile and activity), for the business purposes described under “How we use your information.” We do not sell or share personal information as those terms are defined under the CCPA/CPRA, and we do not sell or share the personal information of minors.

  • Right to know / access the personal information we hold about you.
  • Right to correct inaccurate personal information.
  • Right to delete your personal information.
  • Right to non-discrimination for exercising these rights.

You can exercise the access and correction rights for most data directly in the app, delete your account and data yourself from Settings → Delete account, or contact us at saturnpathsupport@gmail.com. We will not discriminate against you for exercising any of these rights.

Your choices & rights

  • Edit your profile and study data at any time from within the app.
  • Turn email and in-app reminders on or off in Settings (this is also your email opt-out).
  • Delete your account and associated data yourself from Settings → Delete account, or by emailing us.

Data retention & security

We keep your information for as long as your account is active. When you delete your account (in Settings) or request deletion, we remove your account and associated study data. We use industry-standard safeguards including encryption in transit and database row-level security so that each account can access only its own data. No method of transmission or storage is 100% secure.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the effective date above and, where appropriate, by notice within the app.
