Accounts
- How do I make an account?

- Yes. Your flashcards, mistakes, scores and plan are saved to your account, so sign in on any device and carry on.
- I forgot my password.
- Use “Forgot password” on the sign-in screen and we’ll email you a reset link. If you signed up with Google, sign in with Google again.
Free day
- Is there a free trial?
- Every new account gets one free day with everything unlocked. It starts automatically when you first sign in. No card needed.
- Can I get another free day?
- The free day is one per new account, and one per browser on the website. After that, a pass keeps everything unlocked.
- Are the questions on this website free?
- Yes. The sample questions on each subject page are free, with answers.
Passes and payment
- How much does Lock in cost?
- A$5 for one week or A$20 for three months. Both unlock everything in the app for your year.
- Does it renew automatically?
- No. It’s a one-time payment with no auto-renew. When your pass ends, you can buy another if you want one.
- How do I get my key?
- It appears straight after paying. Buy inside the app while signed in and it’s saved to your account automatically. Buy on the website and enter the key in the app once, and it’s saved from then on.
- Who processes the payment?
- Stripe. Checkout happens on Stripe’s secure page, Stripe handles any sales tax, and Lock in never sees your card details.
- Can I get a refund?
- Yes, within 48 hours of buying if the pass hasn’t been substantially used. After that, refunds are only given where the law requires. See the refund policy.
Devices
- What can I use Lock in on?
- Any modern browser, including phones, tablets and Chromebooks, at lockinstudy.site/app. There are also desktop apps for Mac (Apple Silicon) and Windows on the download page.
- Is there an iPhone or Android app?
- Not in the app stores. Open lockinstudy.site/app in your phone’s browser; it works the same way.
AI and accuracy
- How accurate is the AI marking?
- Each written answer is marked against the question’s own criteria and model answer, which keeps feedback specific. AI can still make mistakes, so treat a mark as a guide and check anything surprising with your notes or your teacher.
- Which AI does Lock in use?
- Claude, made by Anthropic. Only the AI features use it: marking written answers, Explain my mistake and Ask AI.
- Is there a limit on AI use?
- Yes, there’s a daily limit on AI requests for each pass. The rest of the app has no limits.
- Will it write my assignment?
- No. Lock in is built to make you answer questions yourself, because that is what moves your marks.
Subjects and years
- Which subjects and years are covered?
- every core subject from Year 7, full Year 11–12 courses (Maths, English, Biology, Chemistry, Modern History, Business Studies, Legal Studies and PDHPE), and any other subject or uni unit built from your own notes. New topics are added as they’re finished, and the subjects page shows what’s available now.
- Can I upload my own notes?
- Yes. Paste your notes or drop in a PDF or text file, and the AI turns them into a study guide, flashcards, multiple choice questions and written questions with a marking guide. Photos and scanned pages need the full Claude AI. See notes to study guide.
- Does it match what my school teaches?
- Topics are written for each year group, but schools order topics differently and set their own texts. Use Lock in alongside your class notes and assessment notices.
Printing
- Can I print a practice exam?
- Yes. Any practice exam can be printed as a plain paper with answer lines, and you can print its marking guide to check your answers afterwards.
Privacy
- What data does Lock in keep?
- Your account details and your study progress, so it can sync. AI features send the question and your answer to Anthropic to generate feedback. Read the privacy policy for the detail.
- Are there ads or tracking?
- There are no ads in the app, and we don’t sell personal information.
- How do I delete my account?
- Email hello@lockinstudy.site from your account’s email address and we’ll delete your account and study data.
