Privacy Policy

Introduction

ExamTeX ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our exam generation service.

By using ExamTeX, you agree to the collection and use of information in accordance with this policy.

Information We Collect

Account Information: When you create an account, we collect your email address and authentication credentials. If you sign in with Google or Apple, we receive the email address (and name, if shared) from that account; with Apple you can choose to hide your email address. We use Firebase Authentication to securely manage your login information.

Uploaded Content: When you upload documents (PDFs, Word documents, PowerPoint slides), we process them only to generate your exam questions. We do not keep your uploaded files. Most PDFs are read in your browser and never uploaded. Other files (Word, PowerPoint, and PDFs that can't be read in the browser) are stored only while your exam is made and are deleted automatically within 48 hours. We never review or share your lecture notes, slides, or course materials.

Lecture Recordings & Audio: How lecture audio is handled depends on where you record it:

- On the ExamTeX mobile app: your lecture is transcribed entirely on your device. Neither the audio nor the transcript is uploaded to us — the transcript is stored only in the app on your phone, and the audio is deleted once it has been transcribed. Only the text you choose to turn into flashcards or an exam is sent to our servers for generation, and only after you have allowed it (see “The ExamTeX Mobile App” below).
- On examtex.com (web): we send your recording to Google's Gemini AI service to produce a text transcript. We do not keep the audio file — it is deleted immediately after the transcript is created (audio that cannot be transcribed is deleted within 24 hours). The resulting transcript is saved to your recordings library so you can reuse it, and you can view or delete it at any time.

We never store, review, or sell your recordings or transcripts, and we do not use them to train AI models. Please only record where you are permitted to and where you have any consent required by law — see our Terms of Service.

Generated Exams: The exams you create are stored in your account so you can access them later. You can delete your exams at any time.

Usage Data: We collect anonymous usage statistics to improve our service, including pages visited and features used.

The ExamTeX Mobile App

The ExamTeX app for iPhone and Android uses the same account as examtex.com. Besides what is described above, it handles the following:

- Microphone: used only to record lectures. Lectures you record or import are transcribed on your phone. The audio and the transcript stay on your phone and are never uploaded to us; the app’s copy of the audio is deleted once it has been transcribed (a file you imported stays where it was).
- Creating with AI: to make flashcards or an exam, the app sends the text you create from (a lecture transcript, or the questions you missed in an exam) to our servers, where Google’s Gemini AI writes the study material (see AI Processing). Your audio is never sent. The app asks first (“Create with AI?”) and sends nothing until you tap “Allow”. You can withdraw this at any time in the app under Profile → “AI generation”; after that, the app asks again before sending anything.
- Reporting AI content: if you flag a deck, card, exam, question or podcast with “Report content”, we store the report with your account so we can review it: what you reported (including a short excerpt of the reported text), the reason, any note you add, whether you use iPhone or Android, and the time.
- Push notifications: if you turn on review reminders and allow notifications, the app stores this phone’s Firebase Cloud Messaging push token with your account, so we can send you study reminders and tell you when a deck or exam you asked for is ready. The token is removed when you sign out of the app or delete your account.
- Local notifications: the daily study reminder you can set in the app is scheduled on your phone and works offline; its time is stored only on your phone.
- Usage statistics: the app uses Google Analytics for Firebase to count which screens and features are used, linked to your account ID. Its advertising features are turned off: this data is not used for advertising or ad personalisation, and the app does not track you across other companies’ apps or websites.
- App Check: Firebase App Check (Apple App Attest, or DeviceCheck on older iPhones; Google Play Integrity on Android) checks that requests to our servers come from the genuine ExamTeX app, to prevent abuse. It does not send your content.

Exam Dates and Reminder Emails

If you add an exam date, we store it with your account and email you reminders (a week before, two days before and the day after). Every email has an unsubscribe link, and you can remove a date from your dashboard at any time. If you buy an Exam Pass, we email you once before it ends.

A few times a year, around exam periods, we may send one email to accounts that have not been used for a while, to say that ExamTeX is there and what has changed. Every such email has an unsubscribe link; one click stops them for good. We do not send study reminders or other recurring marketing email.

How We Use Your Information

We use the information we collect to:

- Provide, maintain, and improve our exam generation service
- Process your uploaded materials and generate exam questions
- Store your exams for future access
- Send important service updates and notifications
- Respond to your inquiries and support requests
- Analyze usage patterns to enhance user experience
- Monitor for abuse, fraud, or activity that violates our Terms of Service

Data Storage and Security

We use Google Firebase for data storage and authentication. Your data is encrypted in transit and at rest. We implement industry-standard security measures to protect your information.

Uploaded documents and lecture audio are processed using Google's Gemini AI service — documents to extract text and generate questions, and audio to produce a transcript. This processing is subject to Google's AI terms of service and privacy practices.

AI Processing

Everything ExamTeX writes with AI (flashcards, practice exams, study guides, podcast scripts and web lecture transcripts) is generated by Google’s Gemini models. We reach them through the Gemini API; when that service is unavailable, the request is sent to Google Cloud’s Vertex AI instead, which runs the same models.

We send only what the request needs (the text, files, lecture audio or video link you are creating from, plus your settings) and only to generate the material you asked for. On the mobile app this is text only, and only after you allow it (see “The ExamTeX Mobile App”). We use the paid versions of both services: under Google’s terms for them, Google does not use your content to train or improve its models. Google may log requests for a limited time, solely to detect and prevent abuse of its services.

Data Retention

- Uploaded files (lecture notes, slides, PDFs): Deleted automatically within 48 hours; most PDFs are read in your browser and never uploaded — we do not retain your course materials
- Lecture audio (web): Deleted immediately after it is transcribed; audio that cannot be transcribed is deleted within 24 hours. We never retain the audio file
- Lecture audio & transcripts (mobile app): Never uploaded — transcribed on your device and stored only on your device; the audio is deleted after transcription
- Lecture transcripts (web): Saved to your recordings library and retained until you delete them or close your account
- Generated exams: Retained until you delete them or close your account
- Content reports (mobile app): Kept with your account until you delete it
- Push tokens (mobile app): Removed when you sign out of the app or delete your account; tokens that stop working are removed automatically
- Account data: Retained until you delete your account

Deleting your account: You can delete your account yourself at any time: on examtex.com through “delete account”, at the foot of every page while you are signed in (also at the bottom of your dashboard, and in the menu on a phone), or in the ExamTeX mobile app (Profile → Delete account; as a guest, Delete my data). This permanently deletes your account and everything in it straight away: flashcard decks, practice exams and their results, podcasts, study guides, lecture transcripts, decks and exams you shared (their links stop working) and any files we still hold for you. If you have a Pro subscription, it is cancelled first so you are not charged again; if it cannot be cancelled, nothing is deleted and you can try again or contact us. If you use ExamTeX as a guest, without an account, “delete my guest data” at the bottom of your dashboard deletes your guest data. We keep a record of each payment (amount, plan and date), no longer linked to your account, for our bookkeeping, for up to 10 years as tax and accounting law requires, and a note that the account was deleted (its internal id and the date, nothing else, kept indefinitely) so that a payment arriving afterwards is stopped instead of reopening it. Lemon Squeezy, our payment provider, keeps its own records of your payments.

Step-by-step instructions, and a way to ask us by email if you cannot use the app or sign in, are on our account deletion page.

Third-Party Services

We use the following third-party services:

- Google Firebase: Authentication, database, and file storage; push notifications to the mobile app (Firebase Cloud Messaging); and App Check, which confirms requests come from our website (using Google reCAPTCHA Enterprise) or our genuine mobile app
- Google Gemini (Gemini API, with Google Cloud Vertex AI as backup): AI-powered question generation and lecture-audio transcription (see AI Processing)
- Google Cloud Vision: Reading the text of scanned PDFs that have no text layer (OCR)
- Google Cloud Text-to-Speech: Turning podcast scripts into audio
- YouTube Data API: If you add a YouTube link, checking the video’s length and that it is public
- Google Cloud Run: Our own LaTeX compiler, which turns the LaTeX of your exams and study guides, including their content, into PDFs
- latex.ytotech.com: An online LaTeX compiler we use only as a backup: when our own compiler does not answer, the LaTeX of that exam or study guide, including its content, is sent there to make the PDF
- Resend: Sending our emails (your email address and the email’s content)
- Lemon Squeezy: Payment processing for subscriptions
- Google Analytics: Which pages and features are used (see Cookies), and Google Analytics for Firebase in the mobile app (see The ExamTeX Mobile App)
- Microsoft Clarity: How pages are used: clicks, scrolling and replays of sessions with typed text and exam content masked (see Cookies)
- Meta (Facebook and Instagram): Measuring our ads (see Cookies)

Each of these services has their own privacy policies governing the use of your information.

Your Rights

You have the right to:

- Access your personal data
- Correct inaccurate data
- Delete your data and account (you can do this yourself; see Data Retention)
- Export your generated exams
- Opt out of non-essential communications

To exercise any of these rights, please contact us at arasmcz@gmail.com.

Cookies

ExamTeX has no cookie banner. Essential cookies and local storage keep you signed in and remember your preferences; nothing else runs unless your region allows it, and you can change what runs in this browser right here:

- In the EEA and Switzerland: no analytics, no session recordings and no ads measurement unless you turn them on below.
- In the UK: Google Analytics runs as first-party statistics (which pages help students) with Google signals off, which UK law allows without opt-in since February 2026; no session recordings and no ads measurement unless you turn them on.
- Elsewhere: analytics, session recordings and ads measurement are on.

Analytics means Google Analytics cookies that tell returning visitors from new ones and show which pages help students. Where session recordings are on, it also means Microsoft Clarity, which records how pages are used (where people click and scroll, and replays of sessions) so we can find what is confusing. Anything you type and the content of your exams are masked before a recording leaves your browser, and we never attach your name or email to a recording. Microsoft processes this data under its own privacy policy.

With analytics on, we also note how you arrived: the site or search that sent you, the campaign tag in the link and the page you landed on. The note is kept in this browser and with your account, so we can see which channels bring the students who find ExamTeX useful. Where ads measurement is allowed it includes the ad’s click ID, which our server may use to tell Google Ads about a purchase. With analytics off, your account only notes your region, as your browser’s time zone tells it. If you answer the one-tap question on the upgrade window, the answer is kept with your account. Deleting your account deletes all of this.

When ads measurement is allowed, the Meta Pixel and our server tell Meta when you sign up or make your first purchase. With that event we send Meta’s own cookie IDs, your IP address and browser type, and a one-way hashed (SHA-256) copy of your email address and account ID, so Meta can match the event to an ad you saw. We send the purchase amount, but never the content of your exams or files. Meta processes this under its own privacy policy. When ads measurement is off, nothing is sent to Meta.

When ads measurement is allowed, Google Analytics also tells Google Ads when someone who clicked one of our Google ads signs up or buys, using Google’s ad click ID and cookies. Google processes this under its own privacy policy. When ads measurement is off, no Google advertising cookies are set and no ad data is shared with Google Ads.

Children's Privacy

ExamTeX is for students and educators aged 13 and over; it is not directed at children under 13, and we do not knowingly collect their personal information. If you are under the age at which you can agree to online services yourself in your country (in parts of the EU this is up to 16), use ExamTeX only with a parent’s or guardian’s permission. If you believe a child under 13 has given us personal information, contact us and we will delete it.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
