ReadToWrite Account & learning data

ReadToWrite is a learning app with accounts. In short: your account holds a profile; your practice work is stored so you — and any teacher or parent linked to you — can see progress; and AI services help generate and grade exercises. The AI services see the work, never your name.

Your account

To use ReadToWrite you sign in with an account. The account includes:

• Sign-in details — a username and a password. We store the password only in a protected, scrambled form (a "hash"), never as the password itself.
• Display name — the name shown in the app. It is required to finish sign-in. It does not have to be your real or full name.
• Date of birth — optional, and added in your profile rather than at sign-up. It is shown as an age in your own profile and to the teacher or parent who supervises the account. It does not change the material you are given.
• Learning profile — your native language, the language and exam you are training for, and your measured level.
• Optional extras — an email address, a phone number, a profile photo, a short "about me" text, and gender. You can leave all of these empty.
• Support notes — our staff can attach a short note to an account when handling a support case.

What your practice creates

• The exercises you complete and the answers you write.
• Scores and grading feedback for that work.
• Which tasks were sent to you, and when you finished them.
• Words and passages you look up while reading (see "AI services" below).
• A service journal: a record of changes to your data (for example "an answer was submitted"), including which device made the change. We use it to keep devices in sync and to investigate problems.
• The most recent time your app contacted us. One date and time per account, overwritten each time. No location, no movement history, no list of past opens. We use it to tell live accounts from abandoned ones and to help with support.

Your devices

A student account may use one iPad, one iPhone and one Mac at the same time. To apply that rule, we store for each signed-in device: its type, system version, app version, and an app-generated device ID. Sign-in sessions last up to 30 days. If you turn notifications on, we store the Apple push token that delivers them.

Who can see a student's work

A student account can be linked to a teacher or a parent using a 6-character code. A linked teacher or parent sees the student's exercises, answers, scores and progress. That is the purpose of the link: it is how an adult supervises the learning. Nobody else sees a student's work. Our own staff access account data only to run the service and to answer support requests.

AI services we use

Parts of ReadToWrite are powered by external AI services, working for us under their service terms:

• Google (Gemini) — generates exercises and grades open-ended answers. For grading it receives the exercise, the passage, the student's written answer, and the student's native language.
• OpenAI — reviews longer writing tasks, and translates words you look up (it receives the word and the sentence around it).
• DeepSeek — generates learning content and writes progress summaries from overall statistics (for example an average score). It does not receive written answers.

What none of these services receive: your name, username, email, phone number, or any account identifier. What we send is the learning content itself.

Some grading is automatic. A grade in ReadToWrite is practice feedback, not an official result. Where a teacher is linked to the account, the teacher can see and review the graded work.

Where your data lives

• Our servers and database run in Japan (AWS, Tokyo region).
• A backup copy is kept in the United Kingdom for up to 14 days, then deleted.
• The AI services above process content in their own countries: Google and OpenAI mainly in the United States, DeepSeek in China.
• Apple distributes the app and delivers push notifications under its own privacy policy.

For readers in the EU and the UK: Japan is recognised by EU and UK law as a safe destination for personal data (an "adequacy" decision). For the US providers we rely on their published data-processing terms.

Why we are allowed to use this data

In the words the law uses: most of this processing is needed to provide the service you signed up for ("performance of a contract"). The device rule, the service journal and the last-active time protect the service and its users ("legitimate interests"). Optional profile fields are used with your agreement ("consent"), which you can withdraw at any time by emptying the field or contacting us.

How long we keep it

• Your account and work — for as long as the account exists.
• If you ask us to delete the account — we erase its personal data within 30 days. Backup copies expire within a further 14 days.
• Finished sign-in sessions — the record of a sign-in is deleted once it is no longer needed.
• Notification registrations — removed when you sign out, and as soon as Apple tells us a device can no longer be reached.
• Your learning history — kept while your account is active, so your progress and your teacher's view of it stay intact.

Children

ReadToWrite is used by school-age learners preparing for exams. A student account is set up through a teacher's or a parent's code, and a student cannot sign in without one. The adult who holds that code gives it to the student, and can see that student's work in the app.

Many countries set an age below which a parent or guardian must agree before a child's data may be used — for example 14 in China and South Korea, 13 in the United States, and between 13 and 16 across Europe. Where that applies, the agreement must come from the child's parent or guardian, or from a school acting together with them.

A date of birth is optional. It is not asked for when an account is created; it can be added later in the profile, and left empty. Where one has been given, we use it to show the learner's age in their own profile and to the teacher or parent who supervises them, and for nothing else. It does not change the material a student is given.

A parent or guardian can ask us at any time to show, correct or delete a child's data, or to end the child's use of the service: privacy@cambtic.com. If you believe a child is using ReadToWrite without a supervising adult, tell us and we will act.

Your rights

Wherever you live, you can ask us to:

• Show you a copy of the personal data we hold about you.
• Correct anything that is wrong or incomplete.
• Delete your account and its personal data.
• Export your data in a machine-readable file.
• Withdraw optional data you gave us earlier.

Write to privacy@cambtic.com. We answer within 30 days. If you are unhappy with our answer, you can complain to the data-protection authority where you live.

Payments

ReadToWrite is free today. If we add paid subscriptions, Apple will process every payment. We never see card numbers or bank details.

KeepReading Translation lookups only

KeepReading has no accounts, no sign-up and no profile. It shows no ads and contains no analytics.

• What stays on your device: your books, your reading position, and your saved vocabulary. They are stored locally and we cannot see them.
• What leaves your device: when you look up a word or translate a passage, the app sends the word or passage, the sentence around it, the book's title and your language pair to our server, which fetches the translation from DeepL, a translation service. This is the app's only network feature.
• Because the app has no accounts, a lookup is not tied to any account or profile.
