PRIVACY NOTICE

What we know about you

Bluebell is used by children, so this has to be readable by one. The short version is written for you. Everything after it is the full legal detail, for a parent, a teacher or a school's data protection officer.

LAST UPDATED · 12 September 2026

The short version

  • We collect the least we can. Your name, email, date of birth, year group, exam boards, and the work you do here.
  • We do not sell anything about you, and we run no advertising and no tracking of any kind.
  • The AI does not know who you are. Your messages go to Anthropic to get a reply, but they are never told your name, your email or your school.
  • Your work is not used to train AI.
  • You can ask to see everything we hold, or to delete it. Email us and it is done within a month, usually the same week.
  • A few words we watch for. If you write something suggesting you are in danger, it puts your conversation in a list for a person here to read. We would rather tell you that than have you find out later. How that works.

Anything here you are unsure about, ask a parent or a teacher — or email us at privacy@bluebellai.org and we will answer in plain English.

1. Who is responsible for your data

The data controller is Bluebell AI Ltd, a company registered in England and Wales, company number 17183714, registered office [REGISTERED OFFICE ADDRESS].

We are registered with the Information Commissioner's Office under registration number [ICO REGISTRATION NUMBER].

We have not appointed a statutory Data Protection Officer, as we are not required to under Article 37 UK GDPR. Privacy questions and requests go to privacy@bluebellai.org, which reaches the person responsible for data protection at Bluebell.

Where a school provides Bluebell to its pupils under a school code, the school and Bluebell are independent controllers for their own purposes: the school decides which pupils are offered access, and we decide how the service itself operates. We are not a processor acting on the school's instructions.

2. What personal data we collect

2.1 Data you give us

DataWhen
Username, display name, email addressAt sign-up
Password, stored only as a bcrypt hash — never in a readable formAt sign-up
Date of birthAt sign-up, to check age (see section 8)
School code, where you have oneAt sign-up
Year group, stage, exam boards, subject confidence, tier and study preferencesDuring set-up and in settings
Your name, email and message if you use the contact formWhen you contact us

2.2 Data created as you use Bluebell

DataNotes
Your conversations with the tutorBoth what you write and what the tutor replies
Images you attach to a messageStored with the message. Photographs of your own work may show more than the work — see section 6
Quiz answers, marks, topics covered, XP and streaksHow progress pages are built
Interview and UCAT practice attempts, answers and scoresPro features
Counts of AI requestsUsed to apply your weekly allowance
A one-way salted hash of your IP address, and a random device markerAt sign-up only, to spot one person opening many free accounts. The IP address itself is never stored

2.3 Payment data

Payments are taken by Stripe. Card numbers never reach Bluebell's servers and we never see or store them. We keep the payer's email address, the Stripe customer and subscription identifiers, the plan and the renewal date.

2.4 Special category data

We do not ask for health, ethnicity, religion or any other special category data. Two routes bring it to us anyway, and we would rather name them than pretend otherwise:

3. Why we process it, and our lawful basis

PurposeLawful basis
Creating and running your account, and providing tutoring, quizzes and progress tracking Contract — Article 6(1)(b). Where a parent or school arranged the account, our basis for the child's data is legitimate interests — Article 6(1)(f) — in delivering the service they arranged
Taking payment and managing subscriptions Contract — Article 6(1)(b)
Keeping accounting and tax records Legal obligation — Article 6(1)(c)
Checking age at sign-up Legal obligation — Article 6(1)(c), to comply with data protection law as it applies to children
Security, rate limiting, and stopping one person opening many free accounts Legitimate interests — Article 6(1)(f). Our interest is keeping the service available and affordable; the data used is minimal and hashed
Safeguarding review of flagged messages Legitimate interests — Article 6(1)(f), and vital interests — Article 6(1)(d) — where there is a risk to life. For the special category element, DPA 2018 Schedule 1, Part 2, paragraph 18
Answering your messages and providing support Legitimate interests — Article 6(1)(f)

We do not rely on consent for any of the above, which matters for a service used by children: a child under 13 cannot give valid consent to an online service on their own behalf, so a service that depended on it would be on weak ground. You can ask us to stop processing based on legitimate interests at any time — see section 9.

We do not use your data for marketing, we do not sell or rent it, and we do not share it with data brokers or advertisers.

4. Who else receives your data

We use a small number of suppliers. Each is bound by a written contract to process data only on our instructions, and none of them may use it for their own purposes.

WhoWhat they receiveWhere
Anthropic
AI model provider
Your message, any image attached, the topic, and your year group, stage and exam board. Never your name, email, username or school. United States
Stripe
Payments
The payer's email and card details, which they collect directly Ireland and United States
Railway
Hosting
Everything, as the infrastructure the database and application run on [RAILWAY REGION]
Resend
Transactional email
Your email address and the contents of account emails, such as a password reset United States

4.1 Content loaded from other websites

Some pages load fonts and stylesheets from Google Fonts, jsDelivr and unpkg. When your browser fetches those files it connects directly to those services, which means your IP address is disclosed to them. They are not our processors and we have no contract with them covering this. They are used only to deliver fonts and stylesheets, not to track you, and we are working to serve these files from our own servers so that the disclosure stops.

4.2 Others we may disclose to

5. Sending data outside the UK

Anthropic, Stripe and Resend process data in the United States. Those transfers are made under the UK International Data Transfer Addendum to the European Commission's standard contractual clauses, which is the safeguard provided for in Article 46 UK GDPR. We hold a copy of each agreement and will provide it on request.

6. A specific word about photographs

You can attach a photograph to a message — usually a picture of a page of working. A photograph taken in a bedroom often contains more than the page: faces, a room, a name on a book. Those images are stored with the message, are sent to Anthropic to be read, and are deleted when the message or the account is deleted.

Send a photograph of the work rather than of yourself, and crop out anything you would not want stored.

7. How long we keep it

DataKept for
Account details, conversations, quizzes and progressAs long as the account is open, and deleted when it is closed
Records of payments and subscriptionsSix years after the end of the financial year they relate to, as company and tax law requires
Records of how many AI requests were madeKept indefinitely for cost accounting, but unlinked from you when your account is deleted, so they no longer identify anyone
Safeguarding review recordsDeleted with the account. We are not a school and hold no safeguarding record that outlives it
Contact form messages[CONTACT FORM RETENTION PERIOD]
BackupsDeleted data disappears from backups as they are rotated, within [BACKUP ROTATION PERIOD]

8. Children

Bluebell is designed for students aged 13 and over, and we follow the ICO's Age Appropriate Design Code.

9. Your rights

Under UK data protection law you have the right to:

How to ask. Email privacy@bluebellai.org. There is currently no button in settings that deletes an account, so a request has to come to us by email — we are adding one. We reply within one month as the law requires, and in practice usually within a few days. It is free.

Complaints. If you are unhappy with how we have handled your data, tell us first and we will try to put it right. You also have the right to complain to the Information Commissioner's Office at ico.org.uk/make-a-complaint or on 0303 123 1113. You do not have to come to us first.

10. Automated decisions and AI

The tutor's replies are generated by an AI model, so in that sense the service is automated throughout. But no decision is made about you that produces a legal or similarly significant effect: we do not grade your coursework, predict your results, report on you to anyone, or decide anything about your education. Article 22 UK GDPR — the right not to be subject to solely automated decisions — is therefore not engaged.

Your work is not used to train AI models. Our AI policy sets out which model is used, what is sent to it, and what is not.

11. Cookies

We run no analytics and no advertising trackers of any kind — no Google Analytics, no Meta pixel, nothing. That is why you have never seen a cookie banner: there is nothing to ask you about.

CookiePurposeLasts
sessionKeeps you logged in7 days
csrf_tokenStops forged form submissionsSession
admin_sessionStaff access only12 hours
bb_deviceA random marker so we can see one browser opening many free accounts. It identifies a browser, not a person, and is never used for advertising1 year
bb_ageSet only if a sign-up is refused on age, so the date cannot simply be retyped30 days

We also store your light or dark theme choice, and which tab you last used, in your browser's local storage. That never reaches our servers.

12. How we protect it

No system is perfectly secure. If a breach ever affects your rights and freedoms we will tell the ICO within 72 hours, and we will tell you directly where the law requires it.

13. Changes to this notice

The date at the top is when this was last changed. If we ever change something significant — a new supplier receiving your data, a new purpose, a new lawful basis — we will say so on the site before it takes effect rather than quietly updating the page.

14. Getting in touch

privacy@bluebellai.org for anything in this notice, or the contact page for anything else. If it is about a child's safety, say so in the subject line and we will read it the same day.
