What we collect, why we collect it, where it goes, and how you can delete it.
PrepHSC is run by a partnership of Aditya Tamhankar and Pranay Mittal. "We", "us" and "our" mean that partnership.
We handle your personal information in line with the Australian Privacy Principles in the Privacy Act 1988 (Cth).
You can sign up and sign in with your Google or Apple account instead of a password. We ask them for your name and email only. They send us:
Google also sends a link to your profile photo, because it gives your name and photo together. We delete the link before it is stored. We never get your Google or Apple password, and nothing else from those accounts.
If you choose Hide My Email with Apple, we get an address Apple makes for you, and Apple forwards our emails to you. If you already have a PrepHSC account with the same email, signing in with Google or Apple adds it to that account.
Before you can use PrepHSC this way, you finish signing up: your first name, your year, and the same box as at sign-up. Until then, your account can do nothing else. If you cancel, we delete what Google or Apple sent us. If you do not finish, we delete it about a day after you last signed in.
Google and Apple handle your sign-in under their own privacy policies.
Your account, answers, photos, marks and weaknesses are stored with Supabase in Sydney, Australia.
Photos sit in private storage. Before a photo leaves your device, the website saves a clean copy that has no location data in it.
Anthropic, in the United States. Your written answers and photos are sent to Anthropic, our AI provider, to be marked. We send your answer or photo with the question and its marking criteria. We do not add your name or email, but anything on your page goes with it, so leave your name off your working. Multiple choice answers are not sent.
Anthropic keeps what we send for up to 30 days, and its staff may access it for safety and security review. Then it is deleted. If Anthropic's safety systems flag something, it can keep it for up to 2 years. It can also keep it longer if the law requires it.
Stripe. When you open Stripe's payment page, we send Stripe your email and an account reference. If you buy Pro, Stripe handles your payment and holds your payment details under its own privacy policy. Stripe may handle your information outside Australia, including the United States.
Our team. Answers the system cannot mark safely, and answers you flag, are sent for review. The team members who review them can see the answer, the photo and the marks proposed. The review screens do not show your name or email. The people who run PrepHSC can also reach stored data when they need to fix a fault. Our team may also read answers, without your name or email attached, to check and improve marking. A name you write on your working stays on it, so leave it off.
Your study groups. Members of a group you join see your nickname, and your scores on timed papers unless you turn off Show me in group rankings. They never see your name, email, school, age or photo. Your PrepHSC standing is a band, such as Top 10%, worked out from the scores of students who chose to take part. It never shows anyone's name, nickname or exact place. It is not an official NSW, HSC or ATAR rank.
Hosting. We use other services to run the website, the marking service and our emails. These services may handle your information outside Australia, including the United States.
We also share information if the law requires it.
We keep your account, answers, photos, marks, weaknesses, plan details, nickname, groups and ranking scores until you delete your account, or until we delete it after 2 years with no sign-in.
When you change your nickname, nobody else can take your old one for 30 days. We keep that old nickname for those 30 days, with nothing that links it to you.
If you do not sign in for 2 years, we delete your account in the same way as the section below explains. We send you a warning email 30 days before. Signing in, or opening PrepHSC while you are still signed in, keeps your account. We do not delete an account for this while you are paying for Pro.
You can delete your account from your Account page. Choose Delete my account and type your password. If you sign in with Google or Apple, we email you a 6-digit code to type instead. You cannot undo it.
This signs you out straight away. Our marking service then deletes your login, answers, photos, marks, weaknesses, plan details, your record of agreeing to the Terms, and your marketing email choices and the record of the marketing emails we sent you. If you have paid for Pro, it also deletes your Stripe customer record, which ends any subscription.
It also deletes your nickname, your group memberships, the reports you made, the reports about your nickname, your rankings settings and your ranking scores. A group you own passes to the member who joined it first, or is deleted if nobody else is in it.
Some copies last longer, because we cannot reach them:
We also keep the cost of each marking run. It no longer links to you, and it holds nothing you wrote.
You must be 13 or over to use PrepHSC. Many HSC students are under 18. If you are, a parent or guardian should read this policy, and must know you are signing up. At sign-up, or when you finish signing up with Google or Apple, you tick a box to say you are 18 or over, or that your parent or guardian knows you are signing up.
We do not ask how old you are, so we treat every account as one that may belong to someone under 18. Marketing emails stay off unless you turn them on, and we do not use advertising or analytics cookies. We keep when you ticked the box. We rely on what you tell us, and we do not check your age or contact your parent or guardian.
If you signed up when sign-up still asked your age, we also keep the age group you chose then, and whether you said a parent or guardian agreed.
Parents and guardians do not get a login or a view of your account. A parent or guardian with a question can email us at support@prephsc.com.au.
We use cookies to keep you signed in and to remember your dark mode choice. We do not use advertising or analytics cookies.
If we change this policy, we post the new version on this page.
To ask a question or make a privacy complaint, email us at support@prephsc.com.au. Tell us what happened and what you want us to do about it.
If we do not reply within 30 days, or you are not happy with our reply, you can complain to the Office of the Australian Information Commissioner at oaic.gov.au.
