Privacy policy

Last updated 18 September 2026

Study Guide Maker ("we", "us") is a service that builds study materials with the help of AI, from the content you provide — pasted text or files — or from a topic you name. Today it builds step-by-step courses with quizzes and tests, and study notes to read, print or export; whatever it builds, and in whatever format, this policy calls it your study materials. You use it through our Chrome extension. This policy explains what information we handle, why, and the choices you have. It covers our extension, our website at aistudyguide.net and everything else we offer. By using any part of it, you understand that your information will be handled as described here. Using Study Guide Maker is also subject to our Terms of use.

The short version

What you submit is sent to our service and to third-party AI service providers to build your study materials.
Your study materials, answers, progress, highlights and bookmarks are saved in your browser.
We use an anonymous install ID to count the credits your study materials use, and keep the feedback you choose to send.
We collect anonymous usage statistics, such as whether quizzes and tests are passed, to learn whether the product helps people learn. They never include the content you submit, and you can turn them off.
We do not sell your data or use it for advertising.

Information we handle

Content you submit: the text and files you provide and the options you choose, such as the language it is written in. They are sent when you ask for study materials to be built — in one request for something short, and for something built in parts, first to plan it and then, part by part, the piece of your content each part is built from.
An anonymous install ID: a random identifier created by the extension and not tied to your name, email or Google account, used to count credits and apply usage limits.
Credit records: for each thing built, its price in credits, which parts were built, how many attempts building them took, and what processing cost us, linked to the anonymous install ID. They do not include the content you submit or the study materials themselves.
Usage statistics: how your study materials are used — events such as opening the first part of something built, finishing a quiz or a final test with its score and whether it was passed, a part that could not be built, and the days you come back to review, linked to the anonymous install ID. They do not include the content you submit.
Feedback you send: your rating and comment, with basic technical details such as the extension version.
What you give us directly: if you create an account, buy something, subscribe to our updates or write to us, what you provide then — such as your name, email address, payment details and the content of your message.
Technical information: such as your IP address, request times, browser type and error details, which our service needs to run, stay secure and prevent abuse. When something goes wrong, our technical logs record what failed and how large it was, not what you or the AI service wrote.

We also handle what any website and app handles: the pages and screens you view and the site you came from, device and browser details, approximate location by country and city, and information collected through cookies, similar storage and analytics services — to keep things running, remember your preferences, measure how they are used and improve them. Your browser can tell you when a cookie is set or refuse cookies altogether; some things may stop working if you refuse them.

We may combine the information we hold about you, and we may aggregate it or strip it of anything that identifies you. Aggregated and de-identified information is no longer about you, and we may use and share it for any purpose.

How we use it

To build the study materials you ask for.
To count credits, apply usage limits and prevent abuse.
To keep the service running and secure, and to fix problems.
To measure, in aggregate, whether the product helps people learn, and to improve it.
To understand how people find and use what we offer, and to improve it.
To create and manage your account, and to take payment, where those apply.
To reply to you, and to send you the updates you asked for.
To comply with the law, and to enforce our Terms of use.

Who we share it with

AI service providers that process the content you submit to build your study materials, under their own privacy terms.
Infrastructure providers that host, secure and back up our service on our behalf.
Analytics, payment and other service providers that help us run, measure and improve what we offer, on our instructions.
Our current or future affiliated companies.
Authorities, where the law requires it, and where it is needed to enforce our terms or to protect our rights, our users or the public.
Anyone you ask us to, with your consent.

Please do not submit content you are not comfortable sharing with AI services.

Business transfers. As Study Guide Maker develops, we may sell or transfer some or all of it. In such a transaction, including while one is being considered, the information described in this policy may be among the assets transferred.

Why we are allowed to handle it

Where the law asks us to name a legal ground for handling information about you — as the laws of the European Economic Area and the United Kingdom do — ours are these:

To do what you asked for. Building your study materials, counting credits and applying usage limits is the service you came for, and we cannot provide it without handling what you submit.
Our legitimate interests. Keeping the service running and secure, preventing abuse, and understanding in aggregate whether the product helps people learn. You can object to the last of these at any time by turning off usage statistics in the extension's settings.
Legal obligations. Where the law requires us to keep or disclose something.
Your consent, where the law requires consent and you have given it. You can withdraw it at any time; withdrawing it does not undo what was done while it stood.

What stays in your browser

Your study materials, your answers and progress, highlights, bookmarks and settings are stored in the browser's extension storage on your device. While something is being built, the files you attached are kept there too, and they are deleted once it is finished. You can delete any of your study materials in the extension, and removing the extension deletes everything it stored.

If you save a copy of your study materials in the extension's settings, the file is saved on your device.

International processing

We and our providers may process information in the United States and in other countries, which may be different from the country where you live, and which may not give it the same protection your own laws do. Where we transfer information out of the European Economic Area or the United Kingdom, we take the measures the law asks of us to see that it stays protected.

Other sites and services

What we offer may link to sites and services we do not run. What they do with your information is governed by their own policies, not this one, and we are not responsible for them.

How long we keep it

We keep the content you submit for as long as we need it to build your study materials and to keep the service running. Credit records, feedback, usage statistics and other information are kept only as long as needed for the purposes above, for security, or as required by law, and are then deleted or anonymised. Technical logs are short-lived and are overwritten as new entries arrive. Backups are kept for a limited period and then deleted.

Security

We use reasonable technical and organisational measures to protect information, including encrypted connections. No system is perfectly secure, and we cannot guarantee absolute security.

Chrome Web Store policy

The use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Permissions the extension uses

Storage and unlimited storage keep your study materials and progress on your device.

Your rights and choices

Two things are in your hands without asking us: you can delete your study materials in the extension at any time, and you can turn off usage statistics in the extension's settings — after that, no statistics are sent.

Depending on where you live, you also have rights over the information we hold. Wherever you are, we will honour these to the extent the law allows:

To know whether we hold information about you, and to see it.
To have it corrected if it is wrong, or deleted.
To object to or restrict how we handle it.
To withdraw your consent, where we relied on it.
To receive a copy of what you gave us, in a form you can take elsewhere.
To complain to your data protection authority. We would rather you came to us first, so that we can put it right.

Write to the address below to exercise any of these. Because no account is involved, what we hold is linked only to an anonymous install ID, and an email alone does not tell us which one; we will reply with what we need in order to find your records.

Children

Study Guide Maker is not intended for children under 13, and we do not knowingly collect their information. In the European Economic Area, where the age of digital consent is 16 unless the country you live in has set it lower, a child below that age should use Study Guide Maker only with the consent of a parent or guardian. If you believe a child has sent us information, contact us and we will delete it.

Changes to this policy

We may update this policy. When we do, we change the date at the top of this page.

Who is responsible, and how to reach us

Study Guide Maker is an independent project, and it is the operator responsible for the information described in this policy. Questions about this policy or your data, and any of the requests above: .
