About ai45, privacy and terms
Last updated 6 November 2026
About us
ai45 (ai45.xyz) is an independent study platform for IB Diploma students, built and run by a small student team based in Indonesia. The name is "AI" plus 45, the top IB score. In this document "ai45", "we", "us" and "our" mean the people who run ai45.xyz, and "you" means anyone who visits or uses it.
Our line is the skills, not the shortcuts. We help you learn: notes, practice questions with explanations, study tools, SAT practice, university research and focus sessions. We do not write assessed work for you, and our tools are built to explain, quiz and critique rather than to hand over answers to work you'll submit.
What ai45 is not
- We are not part of, affiliated with or endorsed by the International Baccalaureate Organization (IBO). "IB", "International Baccalaureate" and "IB Diploma Programme" are trademarks of the IBO. Our notes, questions and guides are our own and are not official IB material.
- We are not affiliated with or endorsed by the College Board. "SAT" is a trademark of the College Board. Our SAT questions are original and are not official SAT questions.
- We are not affiliated with Anthropic, OpenAI, Google, Perplexity, Spotify or any other company whose products we mention. Their names and logos belong to them.

Questions about anything on this page, privacy requests, or permission requests: email privacy@ai45.xyz. We aim to reply within 7 days.
Privacy policy
Short version: we collect what we need to run your account and your study tools, we never sell your data, we show no ads, we use no advertising or tracking cookies, and you can download or delete your data whenever you like.
1. Who is responsible
ai45 is responsible for the personal data described here. Contact us at privacy@ai45.xyz.
2. What we collect
When you make an account
- Your email address and a password. Passwords are handled by our sign-in provider and stored only as a secure hash; we never see or store your actual password.
- If you turn on two-step sign-in: an authenticator app link, or the phone number you choose for codes.
- Before launch, a request to get in: your email, the name you give and any note you write, and whether an admin let you in.
What you tell us when you set up
- Your name, school year, IB subjects and levels, what you'd like help with, the AI tools you use, SAT status, scores and test dates if you give them (the ACT only if you add it to your Uni prep scores), university interests, how you heard about us, and whether you want the newsletter.
Your profile (for friends)
- Your @username, display name, picture (a colour and letter or emoji, one of your fish, or a photo you upload), bio, school, year and subjects, and switches for what friends may see. A small summary of your numbers (focus time, streak, fish, questions answered, notes read) is shared with your friends only if your switches allow it.
What you create and do on ai45
- Your study data: notes you've read, highlights, your own notes, annotations, notebooks and handwriting, working you write on questions, saved and marked questions, SAT practice and results, vocab progress, uni prep lists, to-dos and calendar blocks, Lock in sessions, fish and aquarium.
- Social data: friends and friend requests, groups, things you share with friends or groups, invites, and notifications.
- If you use teacher tools or join a teacher's quiz: quiz content, your answers and scores, and, if the teacher turns it on, when you leave the quiz tab.
- Plans: access codes you redeem and the plan they give you.
- Usage counts for AI features: how many AI messages or checks you've used in the last day (a time and a count, not what you asked).
- Problem reports you send with the Report a problem button: what it's about, what you write, the notes you pin on the page, and technical details to help us fix it (the page, your browser and window size, colour theme, the time and any recent error messages on that page). Each report includes a screenshot of the page with your marks; use Hide to cover anything private first. The report goes by email to the ai45 team; the screenshot is kept only in that email, never in our database.
Live features (not stored)
- Online status: while you're on ai45, your friends can see that you're online, whether you're in a Lock in session and which room you're in.
- Lock in phone check: a linked phone sends its motion and orientation (face down or picked up) to your laptop as it happens. We use it only to run the session and do not store it.
- Rooms and boards: your name, avatar and session progress are shown to people in the same Lock in room; ink on a shared board is sent to the people on it.
- Camera: only if you choose to scan a friend's QR code. The picture stays on your device and is never uploaded.
What our servers see automatically
- Like any website, our hosting provider receives technical data such as your IP address, browser type and the pages requested, kept in short-lived server logs for security and fixing problems. We do not run analytics or advertising trackers.
3. Why we use it
- To run your account and every feature you use, and to keep your data in sync between devices (to provide the service you asked for).
- To show the things you choose to share to the people you share them with.
- To keep ai45 safe: sign-in security, preventing abuse and limiting how much any one account can use the AI.
- To email you about your account (sign-in links, password resets, access decisions) and, only if you opted in, our newsletter.
- To improve ai45, using our own view of how features are used. We do not build advertising profiles.
We rely on your agreement (consent) for the newsletter, optional profile details, a phone number for two-step sign-in, and connecting other services. You can withdraw it at any time in your settings.
4. Who we share it with
We never sell your personal data or share it for advertising. We use a small number of service providers who process data for us, under their own security and privacy commitments:
- Supabase: accounts, database, file storage (uploaded pictures) and live connections.
- Vercel: hosting the website and running our server functions.
- Anthropic (Claude): the AI behind AI₄₅. See the AI tab for exactly what is sent.
- Resend: sending emails.
- Content delivery networks (jsDelivr, Fontshare, Google Fonts): fonts and code libraries load from them, so they see your IP address when they do.
- GitHub: hosts the desktop app downloads.
- MET Norway: only after you choose a weather location, your browser requests a forecast using rounded coordinates. The provider receives those coordinates and your IP address. Your chosen location and cached forecast are saved on your device, outside your ai45 account. Use Weather → Change location → Clear location to remove them.
- Only if you choose to connect them: Spotify (to show what's playing) and Google Calendar (to sync your calendar). These are off unless you sign in to them.
We may also disclose data if the law requires it, or to protect the safety of our users or others.
5. Where it's stored
Our providers run servers in several countries, so your data may be stored or processed outside the country you live in, including outside Indonesia. We only use providers with appropriate security measures in place.
6. How long we keep it
- Your account and the data tied to it: until you delete your account.
- When you delete your account, your account and its data are deleted straight away. Copies may remain in our providers' backups for a limited time before they are overwritten.
- A pre-launch access request: until an admin removes it or the gate is closed for good.
- Server logs and AI usage counts: a short time (usage counts are cleared after two days).
7. Your rights
You can:
- See and download your data: Account → Download my data.
- Correct it: change your answers, profile and settings at any time.
- Delete it: Account → Delete account removes your account and its data.
- Withdraw consent, turn off the newsletter, hide things from friends, or ask us to stop or limit something.
- Ask us anything about your data, or make any other request under the law that applies to you (for example Indonesia's Personal Data Protection Law, or the GDPR if you're in Europe), at privacy@ai45.xyz. You can also complain to your local data protection authority.
8. Young people
ai45 is made for secondary-school students. You must be at least 13 to make an account. If you're under the age at which you can agree to this policy yourself where you live (for example under 18 in Indonesia, or under 16 in some European countries), you need a parent or guardian's permission. If we learn that an account belongs to a child under 13, we will delete it. Parents can contact us to see or delete their child's data.
9. Security
Everything is sent over encrypted connections (HTTPS). Database rules mean each account can only read its own data and what others chose to share with it, and two-step sign-in is available. No system is perfectly secure; if a breach affects your data, we will tell you and the authorities as the law requires.
10. Changes
We'll update this policy when ai45 changes, and change the date at the top. If a change matters a lot, we'll tell you on the site or by email.
Terms of use
By using ai45 you agree to these terms. If you don't agree, please don't use ai45.
1. Who can use ai45
You must be at least 13. If you're under the age of majority where you live, you confirm that a parent or guardian agrees to you using ai45 under these terms. Before launch, ai45 is open only to people an admin has let in, and we can end that access at any time.
2. Your account
- Give accurate details, keep your password safe and don't share your account. You're responsible for what happens on it.
- One person, one account. Your @username must not pretend to be someone else, be offensive, or use someone else's brand.
- Tell us straight away if you think someone else has used your account.
3. Academic honesty
ai45 is for learning. You are responsible for following your school's and the IB's academic integrity rules. Don't submit anything from ai45, or anything an AI wrote for you, as your own assessed work. Our explanations and AI feedback can be wrong, so check them, and your teacher has the final word.
4. What you must not do
- Copy, download in bulk, scrape, crawl, or harvest any part of ai45, including notes, questions, explanations, pictures, fish art, designs or code, by hand or with any tool, bot or script.
- Republish, resell, share or redistribute ai45 content (for example posting our questions, notes or explanations on another site, in a group chat, a document or a course), except a single link to the page.
- Copy or clone ai45's features, design, layout, look and feel, or code to build or improve another product or service, or use ai45 to train or test an AI model.
- Reverse engineer, decompile or try to get around how ai45 works, including its access gate, plan limits, daily AI limits or security.
- Share, sell or trade access codes, accounts or paid features.
- Use ai45 to bully, harass, threaten, spam or impersonate anyone, or share anything illegal, hateful, sexual or that you don't have the right to share.
- Try to make our AI produce harmful content or work that breaks academic integrity rules, or use it in ways that put an unfair load on our systems.
- Upload viruses or anything that harms ai45 or its users.
5. Things you share
Messages between friends are kept for 7 days unless both people have AI₄₅+. If either person stops having AI₄₅+, the 7 days count from the last time both had it.
You keep ownership of what you create (your notes, working, profile and messages). So that we can run ai45, you give us permission to store, copy, display and send it to you and to the people you choose to share it with, only for running ai45. You confirm you have the right to share it. We may remove content that breaks these terms.
6. Plans and access codes
Some features need a paid plan, unlocked with an access code for a set length of time. What each plan includes and its price are shown on the Upgrade page at the time you get it. Codes are for the person they were given to and can't be exchanged for money. We can change which features are in which plan, but we won't take away a feature you've paid for during the time you paid for without offering a fair remedy.
7. Our service
- ai45 is provided "as is". We work hard to make it accurate and reliable, but we don't promise it will be error-free, always available, or that it will get you any particular grade or result.
- Notes, questions, explanations, university data and AI answers are for study help only. They aren't official IB, College Board or university material and they aren't professional advice. Always check important facts (like university deadlines and requirements) with the official source.
- We can change, pause or end features, or ai45 itself, at any time.
8. Ending your use
You can stop using ai45 and delete your account at any time. We can suspend or close an account that breaks these terms, or if we have to by law.
9. Liability
As far as the law allows, ai45 is not liable for indirect or unforeseeable losses, or for losses caused by things outside our reasonable control, by third-party services, or by relying on content without checking it. Nothing in these terms limits any rights you have by law that can't be limited.
10. The law
These terms are governed by the laws of the Republic of Indonesia. If something goes wrong, please contact us first and we'll try to sort it out. If a part of these terms can't be enforced, the rest still applies.
11. Changes
We may update these terms. The date at the top shows the latest version; if you keep using ai45 after a change, you accept the new terms.

How our AI works
AI₄₅ is ai45's study assistant. It's built on Claude, made by Anthropic, and it's designed to explain, quiz and give feedback, not to do your assessed work.
What is sent to the AI
- Chat: your recent messages, the page you're on, all the words on that page and what you've highlighted, its buttons and boxes and what's in the boxes (never passwords, email addresses or phone numbers), your calendar and to-dos, the ai45 notes that match your question, and, when you ask about something on screen, a picture of your screen. When you ask about a friend, their name, username and profile stats are sent too. Never sent: your chats with friends, your inbox, notifications, your account panel or anything on the account, admin and sign-in pages.
- What the chat can do: when you ask, it can click, type, choose and scroll on the page, open pages on ai45, and add, change, tick off or delete your calendar events and to-dos. It asks you first before anything that deletes, sends or shares. It can't sign you out, change your password or email, delete your account, pay, redeem codes, or touch a test or quiz in progress. Stop ends it straight away.
- Explain and asking about a step: the question and its markscheme, the explanation on screen and your questions about it.
- Check my working: a picture of the working you wrote on the question, with the question and its markscheme.
- Study for a test: the syllabus or topic list you paste.
- Grade my draft: the text of your draft (never the file itself), its type, subject and title; for follow-up questions, your question and the earlier messages in that thread, the report's marks and summary, and the check or passage you ask about with a few lines of the draft around it. Reports stay in your own browser.
- Teacher tools: the picture or topic a teacher gives the tool.
Your name, email and account details are not sent as such, though the words and picture of a page include whatever personal details are on it. Please don't put personal details in what you send.
What happens to it
- ai45 does not store what you send to the AI or what it replies; we only count how many messages or checks you've used today. Conversations in the chat stay in your own browser.
- Anthropic processes it to give the answer, under its commercial terms; it does not use this data to train its models by default.
- Explanations of practice questions don't contain anything about you, so we save them and show the same one to everyone.
Please keep in mind
- AI can be wrong. Check answers against the markscheme, your notes and your teacher.
- Feedback from AI₄₅ is not official IB marking.
- Using AI to write work you hand in can break academic integrity rules. Use it to understand, then do the work yourself.
