Privacy Policy
iStudy · last updated 18 October 2026
iStudy helps school students keep track of their lessons, revise and practise with AI quizzes and an AI tutor, and helps parents follow their progress. This policy explains what information iStudy uses, where it is kept, who it is shared with and the choices you have. It is written for parents and guardians; there is a short version for students at the end.
- Your child’s lessons, photos, notes and quiz answers stay on your devices and, if you turn on sync, in an “iStudy” folder in your own Google Drive. We do not keep them on our servers.
- To create summaries, quizzes and tutor replies, the lesson material and questions are sent to our AI providers (Google and OpenAI). The voice tutor sends your child’s voice to OpenAI while the call is running.
- We keep a small record about each family: the parent’s Google email, first names, year group, how much the AI features are used and simple counts such as lessons added and quizzes done. It never contains lesson content.
- Payments are handled by Stripe. We never see full card details.
- No ads, no selling data, no marketing profiles. You can ask us to delete your family’s data at any time.
1. Who we are
iStudy is provided by iStudy, a sole trader in the United Kingdom (“we”, “us”). We are the data controller for the information described in this policy. Contact us at support@istudyapp.co.uk.
2. What information we use and where it is kept
a) On your devices
Everything you add to iStudy (child profiles, timetables, lessons, photos, PDFs, notes, AI summaries, quiz questions and results, mistakes and settings) is saved in the browser on your device. A random device code is created so the app can tell your devices apart.
b) In your own Google Drive (if you turn on sync)
When a parent turns on Sync across devices, a copy of that data is saved in an “iStudy” folder in the parent’s Google Drive, so it appears on the family’s other devices. When you connect Google, iStudy asks only for:
- your email address, to show which account is connected and to link your plan to it;
- permission to create and manage only the files iStudy creates in your Drive (the “drive.file” permission). iStudy cannot see or change any other files in your Drive.
This copy belongs to you and stays in your Google account. iStudy’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google data is never sold, shared for advertising or used to train AI models.
c) The family record we keep to run iStudy
To run the service, manage free trials and plans, keep AI costs fair and give support, we keep a small record for each family. It is stored securely in the app owner’s Google Drive and is only visible to the app owner. It contains:
| What | Why |
|---|---|
| The parent’s Google email (or the device code if sync is off), the family’s device codes, and the dates the family first and last used iStudy | To recognise your family and link your plan to it |
| The names you entered for who uses each device (for example “Hany, parent”) and your children’s first names, year group and country | To show usage per student and to tailor AI answers to the right school year |
| Counts only: lessons added, lessons with notes or photos, timetable periods and subjects, quizzes done and passed, average quiz score, date of the latest lesson | To understand how iStudy is used and spot problems |
| AI usage: number of AI requests by feature, voice tutor minutes, estimated cost | To keep the service affordable and to apply trial limits |
| Free trial start date, plan status, and whether the family has free access | To run trials and subscriptions and prevent repeated trials |
This record never contains lesson content: no photos, PDFs, notes, summaries, quiz questions or chat messages.
d) Help and support requests
If you send an idea or a support request from the app, we receive what you write, an optional picture or screenshot (which shows whatever was on the screen, possibly a lesson or a child’s name), the name and role entered on the device, your Google email if connected, and the device code. Please avoid including information you don’t want to share.
e) Payments
Subscriptions are processed by Stripe. Stripe collects your card details directly; we never see or store full card numbers. We receive your email, name, billing country or postcode, the plan you chose, its status and invoices.
f) AI features
When you use an AI feature, the information needed for that request is sent to our AI providers, Google (Gemini) and OpenAI, to produce the answer:
- Summaries, quizzes, tests, photo checks and the chat tutor: the lesson’s text, photos or PDF pages, the questions and answers typed in the chat, and the student’s first name, year group and country so the answer suits them.
- Voice tutor: your child’s voice and the conversation are sent to OpenAI while the call is running, to understand and reply. iStudy does not keep recordings.
- Read aloud: the text being read is sent to create the audio.
We use these providers under their business (API) terms, which do not allow them to use this information to train their AI models. They may keep it for a short time to detect abuse, as their terms allow.
g) Technical information
Like any website, our hosting provider (Google Cloud) automatically records basic technical information such as IP addresses and the time of each request, to keep the service secure and working. The app also loads fonts from Google Fonts and, when you take a screenshot for a support request, a small tool from jsDelivr; these services can see your IP address.
h) Cookies and local storage
iStudy uses only what it needs to work: a cookie that remembers you use the app, a sign-in cookie for the app owner’s page, and the browser’s local storage for your data. We do not use advertising or analytics cookies.
3. Why we use it (lawful bases)
- To provide iStudy to your family, including sync, AI features, plans and payments: because it is necessary for our agreement with you.
- Usage counts, preventing misuse, improving iStudy and answering support requests: our legitimate interests in running a fair, reliable and affordable service, balanced against your family’s privacy (we keep only counts and first names, never lesson content).
- Keeping payment and tax records: to meet our legal obligations.
We do not use your family’s data for advertising, we do not sell it, and we do not build marketing profiles of children.
4. Children
iStudy is made for school students and is designed to be set up and managed by a parent or guardian, who agrees to these terms on the child’s behalf. Google sign-in and payments are done by the parent. We collect as little as we can about children: on our side only their first name, year group, country and simple counts. There are no ads, no public profiles and no chatting with other people. Parents can see their child’s lessons and progress in the app, set a parent PIN, turn features off and ask us to delete data at any time. If you believe a child is using iStudy without a parent’s knowledge, please contact us.
5. Who we share information with
We only share information with service providers who help us run iStudy and who must protect it:
- Google: hosting (Google Cloud), sync storage (your Google Drive), our own records (the app owner’s Google Drive), Gemini AI, sign-in and fonts.
- OpenAI: AI tutor, voice tutor, read aloud and some AI answers.
- Stripe: payments and subscriptions.
- jsDelivr: delivers the screenshot tool when you use it.
We may also share information if the law requires it. We never sell personal information.
6. International transfers
Some of these providers process information outside the UK, mainly in the United States. When they do, the transfer is protected by recognised safeguards, such as the UK’s international data transfer agreement or addendum, standard contractual clauses or adequacy regulations.
7. How long we keep it
- On your devices and in your Google Drive: until you delete it.
- The family record and AI usage counts: while you use iStudy, and deleted within 24 months of your last use (or sooner if you ask).
- Free trial start dates: while you use iStudy, so a trial can’t be repeated, and deleted with the family record within 24 months of your last use.
- Support requests: until they are resolved, and then up to 12 months.
- Payment records: as long as the law requires for tax and accounting (usually 6 years).
8. Your rights
You can ask us to give you a copy of the information we hold about your family, to correct it, to delete it, to limit how we use it or to stop using it for our legitimate interests, and to receive it in a portable format. Parents can make these requests for their children. Email support@istudyapp.co.uk from the Google email connected to iStudy, and we will reply within one month. If you are unhappy with how we handle your information, you can complain to the Information Commissioner’s Office at ico.org.uk.
9. Removing your data
- From a device: clear the site’s data in the browser settings.
- From your Google Drive: stop syncing in Settings → Family & plan → Sync across devices, then delete the “iStudy” folder. You can also remove iStudy’s access at myaccount.google.com/permissions.
- Your subscription: cancel in Settings → Family & plan → Your plan → Manage billing.
- Our family record and support requests: email us and we will delete them.
10. Keeping it safe
iStudy uses encrypted connections (HTTPS), Google sign-in tokens are stored in sealed (encrypted) form, the Drive permission is limited to iStudy’s own files, and our records are only available to the app owner. No system is perfectly secure, but we work to protect your information and will tell you and the regulator if a serious breach happens, as the law requires.
11. Changes to this policy
We will update this page if anything changes and show the date at the top. If a change is important, we will tell you in the app.
For students: the short version
Your lessons, photos and notes stay on your devices and in your parent’s Google Drive. When you use the AI tutor or make a quiz, your lesson and questions are sent to an AI company to make the answer, and the voice tutor hears your voice while you talk. We only keep your first name, your school year and how much you use iStudy. We never show ads or sell your information. If you have a question, ask your parent to email us.
