1. Who we are
This Privacy Policy explains how Root (“Root,” “we,” “us,” or “our”) collects, uses, and protects personal information when you use the website at roottutor.comand the related services (the “Service”).
Root is operated by Root Tutor AI Ltd, a company registered in England and Wales and the data controller for your personal information. For any privacy question, contact us at privacy@roottutor.com.
2. What we collect
We collect different kinds of information depending on how you interact with the Service.
2.1 Account information
When you create an account, we collect:
- Your email address and display name (received from Google when you sign in with Google, or entered directly).
- Your Google account identifier (a unique ID provided by Google for OAuth sign-in — not your password).
- A profile photo if your Google account has one. This is optional and only used inside Root.
2.2 Onboarding information
During onboarding you may tell us your year level, the subjects you study, and your goals. This is used to personalise the tutoring experience.
2.3 Usage information
When you use the Service we collect the content you create and the way you interact with Root, including:
- Study sessions and chat messages exchanged with the Root tutor.
- Test papers you generate, your answers, and the feedback Root provides.
- Revision activity, flashcards, progress data, streaks, topics studied and the time at which you studied them. We use this study activity (which topics, how recently, your accuracy on revision walkthroughs) to schedule personalised study and streak reminder emails.
- Files or images you upload (for example, a worksheet you have a question about, or notes and past papers you add to a study unit). When you add files to a unit, Root reads them once to build a short topic summary it keeps as study context for that unit.
- Notes you save in a unit — notes you write yourself, messages or suggestions you save from the tutor, and the short summaries Root generates of a study session or a completed unit.
- Aggregate usage signals such as feature interactions, button clicks, and time spent on the Service.
2.4 Billing information
Payments are processed by Stripe. We do not see, store, or have access to your full payment card number. We receive a Stripe customer ID, the last four digits and brand of the card, your billing country, your subscription tier, and the status of your subscription (active, past due, cancelled, etc.).
2.5 Technical information
Automatically collected when you use the Service:
- IP address (used for rate-limiting and anti-abuse).
- Browser type and version, operating system, device type, and screen size.
- Referring URL and pages viewed within the Service.
- Approximate location derived from IP address (country / region only).
- Cookies and similar technologies (see Section 7).
3. How we use your information
We use the information we collect to:
- Operate, maintain, and improve the Service.
- Generate AI-powered tutoring responses, test papers, and feedback in response to your inputs.
- Personalise the experience to your year, subjects, and learning history.
- Process subscriptions, payments, refunds, and invoices through Stripe.
- Send transactional messages (account confirmations, billing receipts, security alerts, important service notices). You cannot opt out of these while you have an active account.
- Send study reminder emails based on your learning activity, including weekly streak reminders (when your streak is at risk of resetting) and spaced-repetition reminders (when a topic you previously studied is due for review). You can turn these off at any time from Settings → Notifications. They are on by default.
- Send progress and product emails — a monthly recap of your learning activity, occasional notices about new features, and a re-engagement reminder if you stop using Root for a while. These are on by default and you can turn them off at any time from Settings → Notifications or via the one-click unsubscribe link in each email.
- Detect, investigate, and prevent abuse, fraud, and security incidents.
- Enforce our Terms of Service and comply with our legal obligations.
- Analyse aggregated usage to understand how the Service is performing and to plan improvements.
Study reminder emails are scheduled by an automated system that reads your topic history and the time elapsed since you last revised each topic. The schedule follows established spaced-repetition research (review intervals of approximately 3, 7, 16, 35, and 70 days). At most one reminder email per day is sent to any user. The content of these emails is generated from templates filled with your first name, the topic name, the unit name, and the elapsed time — we do not generate per-email content with AI.
4. Legal bases for processing (EEA / UK users)
If you are in the European Economic Area, the United Kingdom, or Switzerland, we process your personal information on the following legal bases:
- Performance of a contract — to provide the Service you signed up for, including running the AI tutor and processing your subscription.
- Legitimate interests — to improve the Service, secure the platform, and prevent abuse, where these interests are not overridden by your privacy rights.
- Consent — for optional analytics and any communications that require consent under your local law. You can withdraw consent at any time.
- Legal obligation — where we must process information to comply with applicable laws (for example, tax or accounting rules).
If you voluntarily include special-category information in your content, we rely on your explicit consent to process it as part of providing the Service (see Section 11).
5. Who we share information with
We do not sell your personal information. We share it only with the service providers listed below, each of which is bound to confidentiality and security obligations and may use your information only to provide services to us.
- Supabase — hosts our database and stores your account, study sessions, and progress data.
- Anthropic, PBC— provides the Claude AI models retained as a backup AI provider. Content is sent to Anthropic's API only if we temporarily fail over to it during a Google outage; in normal operation no content is sent to Anthropic. Per Anthropic's commercial API terms, API content is not used to train their models.
- Stripe, Inc. — processes subscription payments and stores billing details.
- Vercel, Inc. — hosts the Root web application and processes related logs.
- Google LLC— provides “Sign in with Google” authentication, and the Gemini AI models used for all tutoring, test papers, marking, and revision. The relevant inputs are sent to Google's paid Gemini API to produce the reply. Per Google's API terms for paid services, this content is not used to train Google's models. If you opt in to our ad-measurement cookie (see Section 7), Google Ads additionally receives limited conversion data (that a signup followed one of our ads) — never your study content, and never for personalised advertising.
- PostHog, Inc. — provides product analytics so we can understand how the Service is used.
- Upstash, Inc. — provides rate-limiting infrastructure used to protect the Service from abuse.
- Resend, Inc. — sends transactional, reminder, and product emails (welcome emails, referral notifications, weekly streak reminders, spaced-repetition study reminders, monthly learning recaps, re-engagement reminders, and occasional product-update announcements) on our behalf. Resend receives your email address, your first name, and the contents of the email we send you.
Other users (Friends). If you choose to connect with friends on Root, the people you add can see your display name and your gamification stats — your XP, level, weekly XP, week streak, and streak freezes. Friends can never see your study sessions, messages, notes, uploads, or test papers. You can remove a friend at any time.
We keep an up-to-date list of our sub-processors and will provide it on request. We may also disclose information when we believe in good faith that it is required by law, court order, or government request; to enforce our Terms of Service; to protect the rights, property, or safety of Root, our users, or the public (including to protect a child from a serious risk of harm); or in connection with a corporate transaction such as a merger, acquisition, or sale of assets (in which case we will ensure the recipient is bound by privacy commitments at least as protective as this Policy).
6. AI processing and training
Root uses a third-party AI API to generate tutoring replies, test questions, marking, and revision feedback: Google's Gemini API for all of these features (with Anthropic's Claude API retained only as a backup used if Google is temporarily unavailable). When you send a message or generate a test, the relevant content is transmitted to the applicable provider's API, processed to produce the response, and the response is returned to you and stored in your account.
We do not use your study sessions, messages, generated tests, or any other personal content to train AI models. Both providers' commercial API terms state that API content is not used to train their models (this includes Google's paid Gemini API). We do not opt in to any data-sharing programs that would change this.
7. Cookies and analytics
We and our service providers use cookies, local storage, and similar technologies to keep you signed in, remember your preferences, secure your session, measure usage, and prevent abuse. You can disable cookies in your browser settings, but parts of the Service may not work without them.
Root uses PostHog for product analytics. PostHog receives anonymised event data about how you use the Service. Our analytics run in “cookieless” mode — they do not store cookies or persistent identifiers on your device. This is part of our high-privacy-by-default approach for younger users. We do not use PostHog to track you across other websites.
Optional ad-measurement cookie (opt-in only).We run ads on Google to let students and parents find Root. To know whether those ads work, we use Google's conversion-measurement tag (Google Ads) — but only if you say yes in the cookie banner. Until you accept, the tag is not loaded and sets nothing on your device. If you accept, it sets a cookie so Google can tell us that a signup followed one of our ads. It is used strictly for counting conversions: we keep ad personalisation, remarketing, and cross-site profiling permanently switched off — for everyone, including consenting users — because our audience includes teens. Analytics remain cookieless regardless of your choice.
If your browser sends the Global Privacy Control (GPC) signal, we treat it as a “no” automatically and won't ask. You can change your choice at any time here:
Withdrawing consent stops the tag from loading on future visits and instructs Google to stop using ad cookies immediately. Google LLC (and Google Ireland Ltd for UK/EEA users) processes this conversion data as described in Google's privacy documentation; transfers to the US are covered by the EU–US / UK Data Privacy Framework and standard contractual clauses.
8. How long we keep your data
We keep your information for as long as your account is active and as needed to provide the Service. When you delete your account, we delete or irreversibly anonymise your personal information within 30 days, except where we must keep certain records to comply with legal, tax, accounting, or anti-fraud obligations (for example, transactional records held by Stripe for tax purposes), or where information has been aggregated in a way that no longer identifies you.
Inactive free-tier accounts may be deleted after a prolonged period of inactivity (we will give notice by email before doing so).
9. Your rights
Depending on where you live, you may have the following rights regarding your personal information:
- Access — request a copy of the personal information we hold about you.
- Portability — receive your data in a machine-readable format. You can do this yourself from Settings → Download my data.
- Correction — correct inaccurate or incomplete information.
- Deletion — delete your account and the personal information we hold about you. You can do this yourself from Settings → Delete account.
- Restriction or objection — restrict or object to certain processing.
- Withdraw consent — where we rely on consent, withdraw it at any time.
- Lodge a complaintwith your local data protection authority. (UK: the Information Commissioner's Office (ICO). EU: your member-state authority. California: California Privacy Protection Agency.)
US state residents (including California):we do not “sell” or “share” personal information as those terms are defined in the CCPA/CPRA, we honour opt-out preference signals such as Global Privacy Control where legally required, and we will never discriminate against you for exercising any privacy right.
To exercise any right that isn't available in-app, email privacy@roottutor.com. We will respond within 30 days. We may need to verify your identity before acting on your request.
10. Children and young people
Root is intended for users aged 13 and over. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, email privacy@roottutor.com and we will delete it.
Because much of our audience is under 18, we design the Service with children in mind and aim to follow the UK Information Commissioner's Age Appropriate Design Code(the “Children's Code”). For users we know or believe to be under 18, this means:
- privacy-protective settings by default, and collecting only the information we need to provide the Service;
- we do not use their information for behavioural advertising or to build marketing profiles, and we never sell it;
- we do not use manipulative or “nudge” techniques designed to push them to share more information, or to spend more money or time, than they freely choose; and
- we aim to explain our data practices in language a young person can understand (the plain-English summary at the top of this page is part of that).
Parents and guardians.We encourage a parent or guardian to be involved in any under-18's use of Root. A parent or guardian may ask to access, correct, or delete their child's information by emailing privacy@roottutor.com; we may ask for reasonable proof of parental responsibility before acting. If you are between 13 and the age of majority in your country, you may use the free tier on your own, but you must have a parent or guardian's consent to subscribe to a paid plan.
Safety. Root is an educational tool, not a counselling, crisis, or emergency service (see Section 16 of our Terms of Service for sources of help). If we become aware of a serious risk to the safety of a child or any person, we may take appropriate steps, including contacting relevant authorities, to the extent permitted or required by law.
11. Sensitive (special-category) information
We do not ask you to provide special-category information — such as details about your health, race or ethnicity, religious or philosophical beliefs, sexual orientation, or biometric data — and the Service does not need it. Please do not share such information with the AI tutor, or upload documents containing it (about yourself or anyone else).
If you choose to include special-category information in your messages, notes, or uploads, it will be processed as part of Your Content solely to provide the Service to you. By voluntarily providing it, you give your explicit consent to that processing. You can delete it at any time, and we do not use it for marketing or to make decisions about you.
12. Automated processing and personalisation
Root uses automated processing to personalise your tutoring and to estimate your progress and “mastery” of topics. These are learning aids — they are estimates, not formal assessments, and they do not determine your grades, qualifications, or anything of legal effect.
We do not make decisions that produce legal or similarly significant effects about you based solely on automated processing without human involvement.
13. International transfers
Root is a global service. Your information may be processed in countries other than the one you live in, including the United States and the European Union, where our service providers operate. Where we transfer personal data out of the UK, EEA, or other regions with similar protections, we rely on a lawful transfer mechanism — typically an adequacy decision, the UK International Data Transfer Agreement (or Addendum), or the EU Standard Contractual Clauses. You can ask us for more detail about the safeguards that apply.
14. Security
We use industry-standard technical and organisational measures to protect your personal information, including encryption in transit (HTTPS), encryption at rest for our database, access controls, rate limiting, and routine security reviews. No system can be guaranteed 100% secure; if we become aware of a security incident affecting your data, we will notify you and the relevant authority in line with applicable law.
15. Changes to this Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you by email or through an in-app notice before the changes take effect. The “Last updated” date at the top of this page tells you when the current version became effective.
