1. Who We Are

PeakScore is an academic organizer for students. It keeps your classes, homework, tests and grades in one merged day, with Google Classroom, Google Drive and SAT prep as optional add-ons you can connect or turn on if you want them. This Privacy Policy describes how PeakScore ("we," "us," or "our") collects, uses, and protects your personal information when you use our website at www.peakscore.com.br.

For privacy inquiries, contact us at: peakscore2026@gmail.com

2. Information We Collect

2.1 Information you provide directly

• Account information: name, email address, profile picture (if signing in with Google)
• Email preferences and send history: whether you chose to receive study emails, when you made that choice, and when you turned them off if you later do. We also keep a record of which study emails we have already sent you and when, so that we never send you the same one twice.
• Notification subscription: if you turn on notifications, we store the subscription your browser creates for them. That subscription is a web address issued by your browser's own push service, plus two keys used to encrypt each notification so that only your device can read it. It identifies that one browser on that one device, not you by name. We also record when you turned notifications on or off, the reminder level you chose, and a note of the days and times we sent one, so that you never get the same one twice. To time the evening reminders, the app also sends your device's time zone offset and a short summary it works out on your device: your current study streak, how many streak shields you have, and which of the next fourteen days are study days in your week. If five evening reminders in a row are followed by no study at all, we record that and pause the evening reminders for a week.
• Files you upload: if you use Files, we store what you put there. This is usually photographs of your own marked work, mark schemes, drafts and feedback, so it can contain your name, your handwriting, your grades and a teacher's comments, and sometimes another student's name where it happens to appear on the page. You choose every one of these files. Getting to them goes through your account: nobody else can browse or list them. Each file also has its own private web address, long and unguessable, which we store only inside your own account. As with a link from any cloud drive, anyone you deliberately send that address to could open that one file. Deleting your account deletes all of them.
• Google Drive (optional): if you choose to connect Google Drive, PeakScore creates a folder called PeakScore in your Drive and can read, add to, rename and trash only the files it created there. It cannot see, list or open anything else in your Drive. The files stay in your own Google account, not on our servers, and disconnecting or deleting your PeakScore account leaves them exactly where they are. You can revoke our access at any time at myaccount.google.com/permissions.
• Study groups (class groups, optional): if you create or join a study group, we store the study group’s name, the name you chose to show its members (your first name, your initials or a nickname, never your full name), the date you joined, and any exam entries you add to its shared calendar (title, subject and date). If you switch on the study group’s week scoreboard, the placar (off until you choose it, one tap to leave), we also store your study-constancy signals for the current and previous week: which days had at least one completed session and how many sessions, never their content. If you send material to the study group’s shelf, we store that file and its details (name, size, type, who sent it). Exam entries you add are shown to members without your name; we keep an internal record of who added each entry solely so that you can delete your own entries and the study group’s creator can moderate. If you switch on “studying now” (off until you choose it), then while your study timer runs your placar entry also carries that you are studying, which class, and when the timer ends; it carries nothing once the timer stops. Each of these choices is made when you join and can be changed at any time from the study group menu. A study group never contains grades, homework answers, or any other part of your account.
• Study streak sharing (optional, off by default): your streak is counted on your device. If you choose to share it, we store your choice, your first name, a friend code, a generated public name (like @calm-otter-27), your current streak, which days of this week you studied, which weekdays are rest days in your plan and the date you last studied. We never store what you studied, or any grade, for this.
• A page for your family (optional, off until you make a link): if you create one, we store that it is on, when you made it, a number that lets you replace it, and whether you chose to include your class averages. Anyone who has the link sees your first name, how many days you studied this week, your current run of study days, your minutes of focused study this week, and your tests, homework and SAT date for the next two weeks; your class averages only if you turned them on. The page asks search engines not to index it. Making a new link, or turning it off, stops the old one at once.
• Calendar link (optional, off until you make one): if you create one, we store that it is on and a number that lets you replace it. A calendar app you add the link to (such as Google Calendar, Apple Calendar or Outlook) fetches your tests with their class and what they cover, your homework and project titles with their due dates, and your SAT date, and checks for changes on its own schedule. Anyone who has the link can see those dates; turning it off stops it at once.
• Calendar files you import: a calendar file (.ics) you choose, for example your school's, is read on your device and never uploaded. Only the dates you choose to import are kept, as time off or tests in your account.
• Academic profile: current SAT score, target SAT score, target grades per subject, target universities, school name, grade, country, and city, and, for each university you choose, the application round, deadline, checklist and the day you marked it submitted
• School organizer data (optional): school days and hours, outside activities, subjects and their languages, the topics of each class and any flashcards you write, planned tests, homework and study blocks, checkpoint notes, absences, and target, actual and term grades, used only to build your plan and show your progress
• Academic terms: the term structure you choose (semesters, trimesters, bimesters, or your own), and the start and end date of each term, used to organize your classes and to know when to ask you to review them
• Breaks and vacations: the date ranges you mark as time off and whether you chose to keep studying during them, used to pause your plan and to avoid counting those days as missed study
• Grade history: a snapshot of your grade average taken when each term closes, kept so you can see your own progress across terms
• Study preferences: weekly study hours, preferred study days, weak subject areas, study style, and learning resources
• Progress data: completed study sessions, practice test and timed module scores, flashcard reviews, error log entries, and notes
• Chosen SAT date: the official CollegeBoard test date you select during onboarding
• Study profile: your selected intensity level (Intensive, Moderate, or Steady) and the history of any profile changes you make over time
• Mood check-in: optional daily mood selections (e.g., motivated, tired, anxious) recorded after study sessions to help us tailor encouragement and pacing
• Topic mastery scores: per-topic performance data generated from Daily Checkpoints, tracking your estimated mastery percentage for each SAT skill area
• Daily Checkpoint results: question-by-question answers and scores from in-app practice questions used to assess readiness and adapt your schedule
• Adaptive engagement data: internally computed signals (e.g., consistency score, dedication level) derived from your session completion patterns, used to personalize motivational content and schedule adjustments
• Badge and streak progress: records of earned achievement badges and study streak milestones within the app

2.2 Information collected automatically

• Usage analytics: pages visited, time on site, clicks, and navigation paths (via Google Analytics and PostHog, only with your consent)
• Device information: browser type, operating system, screen size, and language preference
• IP address: used for geographic analytics only; not stored individually

2.3 Information from third parties

• Google Sign-In: if you use Google OAuth, we receive your name, email, and profile picture from Google
• Google Classroom (optional): only if you choose to connect it. With your permission we read, on a read-only basis, the names of your active courses, the title and due date of published assignments in them, and whether each of your own assignments has been turned in. We use this for one purpose: to place that work into your PeakScore plan and tick it off once you turn it in. We do not read your grades, the files you submit, messages, or anything belonging to your classmates, and we never write anything back to Classroom. You can disconnect at any time from the School page, which also removes the imported assignments from your plan.
• College Scorecard API: we query the US Department of Education API using your university search terms to provide institution data

2.4 How we treat Google user data

PeakScore's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements. Concretely, this means we use Google Classroom and Google Drive data only to provide and improve the features you asked for, we do not sell it, we do not transfer it to third parties except as needed to provide the service or where required by law, we do not use it for advertising, and no human reads it except where you have given explicit permission, where it is necessary for security purposes, or where the law requires it.

3. How We Use Your Information

We use your information exclusively to:

• Build and display your merged day of classes, homework, tests, and study sessions
• Place homework and due dates into your schedule and build an automatic prep plan for each test
• Track your grades across terms and, if you use the SAT, your practice scores and target universities over time
• Sync assignments from Google Classroom into your plan when you connect it
• Personalize session content, topic ordering, and resource recommendations
• Send you important service-related communications (no marketing without consent)
• Improve the platform based on aggregated, anonymized usage patterns

We do not use your information to: sell it to third parties, display targeted advertisements, build profiles for marketing purposes, or share it with any party other than as described in Section 4.

4. Data Sharing

We share personal data only with:

• Google Firebase / Firestore: used to store your account data securely in the cloud, enabling multi-device access and account recovery. Data is stored in Google's servers under Google's security standards.
• Google Analytics: anonymized usage data only, and only with your explicit consent via our cookie banner. You can opt out at any time.
• PostHog (EU): product analytics: which screens and buttons are used and the errors the app runs into, tied to a pseudonymous code, never your name or email, stored in the European Union, and only with your explicit consent via our cookie banner. You can opt out at any time.
• Vercel: our hosting provider processes requests to serve the website. Vercel may collect standard server logs (IP, timestamp, requested URL).
• Resend: our email delivery provider. It receives your email address and the content of the emails we send you, so that account emails such as address verification, and the study emails you opted into, reach your inbox. Resend acts only on our instructions and is not permitted to use your address for its own purposes.
• jsDelivr: a public content-delivery network that sends two open-source code libraries to your browser: an email helper, and the timetable reader when you tap Scan a photo. Like any website your browser loads, it sees your IP address. It receives none of your PeakScore data, and never your photos: the timetable reader runs on your device.
• Your browser's push service (Google for Chrome and Android, Apple for Safari and iPhone, Mozilla for Firefox): if you turn on notifications, this service relays each notification to your device. It receives the subscription address, but the contents of every notification are encrypted with keys only your device holds, so the service cannot read what a reminder says. We do not choose this company; it is whichever one your browser uses, and turning notifications off ends the relationship.
• Google Firebase Storage: where the files you upload are actually kept. The same company already listed above for your account data, under the same security standards. Access is restricted to your own verified account by server-side rules, so no other student can reach your files even if they know their address.
• Other members of a study group you join: this is one of the few places where PeakScore shows your information to another person (the others are streak sharing, the page for your family and the calendar link, below), and it happens only by your own action. Members of a study group see the name you chose to show (first name, initials or a nickname), the shared exam calendar (exam title, subject and date), your week placar signals only if you switched the scoreboard on (study days and session counts, and the study group’s shared streak built from them), and, only if you switched studying now on, that your timer is running and in which class (never what you studied) and any files you yourself send to the study group’s shelf. They never see your surname, email, grades, homework, your personal files, SAT data or anything else in your account. You can leave the placar with one tap, leave a study group at any time, and remove any file you sent; the study group’s creator can also remove members, files and entries. Study groups can only be joined through an invite link: they cannot be searched or browsed. Deleting your account removes you from every study group.
• People who see your study streak, only if you share it: with Friends, anyone you give your friend code or link to sees your first name and your streak; with Everyone, every PeakScore user can also see your generated public name (never your real name) and your streak on the board. Nobody sees your email, surname, grades or what you studied. Choose Only me at any time and your entries are deleted; a new friend code cuts off everyone who had the old one. Deleting your account deletes them too.
• People you give your family page link or your calendar link to: only what section 2.1 describes for each link, and only while that link is on. You decide who gets a link; we never send it to anyone.

We do not sell, rent, or trade your personal information to any third party under any circumstances.

5. Data Storage and Security

Your data is stored in two places:

• Your browser (localStorage): study progress and preferences are cached locally for fast, offline access
• Google Firestore: your profile and progress are synced to the cloud for account recovery and multi-device access, stored in Google Cloud’s São Paulo region, in Brazil

We implement industry-standard security measures including HTTPS-only access, secure headers (HSTS, X-Frame-Options, X-Content-Type-Options), and access controls on our database. However, no method of transmission over the internet is 100% secure.

6. Your Rights (LGPD / GDPR)

Depending on your location, you have the following rights regarding your personal data:

• Right of access: request a copy of all data we hold about you
• Right of rectification: correct inaccurate or incomplete data
• Right of erasure ("right to be forgotten"): request deletion of your account and all associated data
• Right of portability: download your data in a machine-readable format (available in your dashboard under Settings → Export Data)
• Right to withdraw consent: withdraw analytics consent at any time via the cookie preference link in our footer, and withdraw your consent to study emails at any time via the unsubscribe link at the bottom of every one of those emails, and withdraw your consent to reminders at any time from Settings in the app
• Right to object: object to any processing of your data

To exercise any of these rights, email peakscore2026@gmail.com. We will respond within 15 business days.

7. Data Retention

We retain your personal data for as long as your account is active. If you delete your account, we will permanently delete all associated data within 30 days, except where retention is required by applicable law.

Analytics data (Google Analytics) is retained for 14 months per Google's standard settings, after which it is automatically deleted.

Grade history snapshots are kept for as long as your account is active, because their whole purpose is to show you your progress over time. You can delete them at any point from the School page without deleting the rest of your account. Assignments imported from Google Classroom are removed as soon as you disconnect Classroom.

The switches for your family page and your calendar link are kept while your account is active and deleted with it.

8. Cookies

We use one category of cookies:

• Analytics cookies (Google Analytics and PostHog): used to understand how users navigate the site. These are only placed with your explicit consent. You can withdraw consent at any time by clicking "Cookie preferences" in the footer.

We do not use advertising, tracking, or social media cookies.

9. Children's Privacy

PeakScore is designed for students aged 13 and older. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child under 13 has provided us with personal information, please contact us immediately and we will delete that information.

For users between 13 and 18 years of age, we recommend that a parent or guardian review this policy. Parental consent may be required in certain jurisdictions.

10. International Data Transfers

PeakScore is operated from Brazil. Your account, your school data and the files you upload are stored in Google Cloud's São Paulo region (southamerica-east1), in Brazil, encrypted in transit and at rest. Its server functions run on Vercel, also in the São Paulo region; the website's pages are delivered by Vercel's global network, and product analytics run on PostHog in the European Union, so part of the processing happens outside Brazil under those providers' contractual safeguards, as the LGPD allows for international transfers (article 33). Google maintains appropriate data protection safeguards as described in its Privacy Policy.

11. Legal Basis for Processing (LGPD / GDPR)

We process your personal data under the following legal bases:

• Contract performance: processing necessary to provide the academic organizer, and the optional SAT planning, that you signed up for
• Your request: the family page and the calendar link run only when you turn them on, as part of the service you use. You can turn them off at any time.
• Consent: analytics cookies (you can withdraw at any time)
• Consent: study emails, if you chose to receive them. These are a weekly recap of your own week and occasional encouragement. You can withdraw this consent at any time using the unsubscribe link at the bottom of every one of those emails, or by emailing us. Withdrawing stops the study emails and changes nothing else about your account; we may still send you essential service messages, such as email verification.
• Consent: reminders, if you turned notifications on, at the level you chose. Chill is one notification each morning telling you what is already on your plan for the day, including a test of yours in the next three days and homework due the next day, named by class only. Coach adds one around 19:00 on a study day when you have not studied yet, and Relentless adds a last one around 21:30. Evening reminders are only about your study streak: they never go out on a rest day in your week, a break or a holiday, they stop the moment you study that day or answer "Not today" in the app, and they pause for a week on their own if five in a row go unanswered. Anyone who turned notifications on before levels existed stays on Chill until they choose another level. It is a separate choice from study emails, and your browser also asks you for permission before the first one. You can change the level or withdraw at any time from Settings inside the app, or in your browser's own notification settings, and withdrawing changes nothing else about your account.
• Legitimate interests: security, fraud prevention, and improving our service through aggregated analytics

12. Changes to This Policy

We may update this Privacy Policy from time to time. When we make significant changes, we will update the "Last updated" date at the top of this page and, where appropriate, notify users by email. Your continued use of PeakScore after any changes constitutes your acceptance of the updated policy.

13. Contact and DPO

For any privacy-related questions, data requests, or complaints, please contact us:

• Email: peakscore2026@gmail.com
• Response time: within 15 business days

If you are located in the European Economic Area and have concerns about our data processing that we have not adequately addressed, you have the right to lodge a complaint with your local data protection authority.
