privacy policy

Eular is operated by the Eular team. For anything in this policy, including a request about your data, write to eular.support@gmail.com or use the support form in the app.

Your account. A username, an email address, a password (stored only as a hash, never in a form we can read), and the institution you tell us you study at.

What you upload or write. Lecture PDFs and slides, notes you type into Eular, and past papers you add to a course.

What you do with an exam. The exams generated for you, the concepts they covered, the answers you submit, the marks and feedback, how long you spent, and which marks you flagged as wrong.

Billing. Your plan, when it started and expires, how many exams you have used in the current period, and, if you pay by bank transfer, the payment receipt you upload.

Technical and usage data. Server logs, and product analytics about which screens are used and which actions succeed or fail.

We do not ask for and do not want health data, identity documents, or anything about patients. Please do not put that in a note or an upload.

To run the service you asked for: reading your material, writing questions from it, marking your answers, keeping your history, and showing you where you are weak. To take payment and give you the number of exams your plan includes. To answer support messages. To keep the service working, secure and within its limits, and to find and fix faults.

We use a small number of providers to run Eular. They act on our instructions, and we send them only what each one needs.

Anthropic — the AI models that read your material, write your questions and mark your answers. Your material and your answers are sent there for processing.

Our text-extraction service — turns an uploaded PDF into text so it can be read.

Cloud object storage — stores uploaded PDFs, past papers and payment receipts.

PostHog — product analytics.

Email and payment providers — to send account email and, where offered, to take card payment. We do not see or store your full card details.

We do not sell your data, and we do not share your material with other students. We do not use your material to train AI models.

Your material and your exam history stay until you delete them or ask us to close your account. Payment receipts are kept while we need them to evidence a payment. Logs and analytics are kept for a limited period for security and debugging.

You can delete any note, PDF or past paper yourself, from inside the app, at any time.

There is no self-serve button to close an account yet. Email us and we will delete your account and the material attached to it. We may keep the minimum needed for legal or accounting reasons, such as a record that a payment was made.

You can ask for a copy of what we hold, ask us to correct it, or ask us to delete it. Write to support and we will respond. Depending on where you live, you may have further rights under local data protection law, and nothing here is meant to reduce them.

Traffic to Eular is encrypted. Passwords are stored only as hashes. Access to the production systems is limited to the people who run them. No service can promise perfect security, and we will tell you promptly if something happens that affects your data.

Eular is built for university students and is not intended for children. You need to be at least 16 to hold an account.

If this policy changes we will update the date at the top. If a change materially affects how we handle your material, we will tell you by email rather than only changing this page.
