If your bank offers Knowunity Pro, open your bank's Knowunity page, sign in or create a free account and enter the code from your bank. Pro activates without a payment.

How do I activate Pro through my bank?

Cancel where you bought it: the App Store, Google Play or the Paddle portal for website purchases. Pro stays active until the end of the paid period.

How do I cancel my Knowunity Pro subscription?

Refunds are handled by the store that charged you. Apple and Google decide on App Store and Google Play refunds; website purchases are refunded through Paddle.

How do I request a refund?

Restart the app, sign in with the account you bought with and use Restore Subscription in Settings. If that fails, send us your receipt.

I paid for Pro but it is not active

The store that charged you is the one that manages your subscription. Here is how to tell the App Store, Google Play and website purchases apart.

Where did I buy my subscription?

Most failed purchases are caused by parental controls, a store account from another country or an unsupported payment method. If the app says your payment still needs to be confirmed, do not buy again.

My payment failed or I cannot complete the purchase

Pro is a renewing subscription. It charges again at the end of each weekly, monthly or yearly period until you cancel it in the store you bought it from.

Why was I charged again?

Compare Free and Pro using the features and limits shown in your app. Existing Max subscribers keep their plan, but new Max subscriptions and upgrades are unavailable.

What is the difference between Free, Pro and Max?

A Pro plan belongs to one account. Existing family plans keep working, but new ones cannot be bought at the moment. Website purchases can be moved to another account by support.

Can I share my subscription or move it to another account?

Most sign-in problems come from using a different method than at sign-up. Check whether you registered with Google, Apple, email or a username before resetting your password.

I cannot sign in to my account

Tap Forgot password on the login screen, enter your email and open the link we send. The new password needs at least 8 characters.

How do I reset my password?

Check spam, confirm the address is the one on the account and request a new email. Google and Apple accounts never receive a password email.

I did not receive the confirmation or password reset email

Change your email in Account & security. You normally do not need to enter your password. Some child accounts do not show the email-change option.

How do I change my email address?

Delete your account under Account & security. Cancel any subscription first. Deletion is permanent and the email is free to use again after about seven days.

How do I delete my account?

Sign out other devices from Account & security and change your password. It can take up to 30 minutes for other devices to be signed out.

Someone else may be using my account

Pro, streaks and uploads belong to one account and cannot be merged. Keep the account with your subscription and delete the other.

I have two accounts. Which one should I keep?

Change your studies in Settings under Account settings. If your year is missing, change the school type first.

How do I change my school, school type or year?

Suggest a missing school from the school picker in the app or on the website. Enter its name and city; university suggestions also need a website address.

My school is missing from the list

Edit your username, display name and bio from your profile. Usernames are 3 to 20 characters of letters and numbers.

How do I change my username or display name?

Change the interface language under My language in Account settings. The content language is chosen per upload and follows your country.

How do I change the app language or my country?

Your profile and public uploads are visible to other students. You control who can see your school and whether each upload is public.

Who can see my profile and my school?

Where referrals are available, a friend who is new to Knowunity enters your code on the sign-up screen before creating the account, or uses your invite within 24 hours. You both get three days of Pro.

How does the referral programme work?

Check the message shown and whether referral entry is available in your country. Eligible new accounts can use an invite within 24 hours. Restart the app if an accepted reward is missing.

My referral code did not work or the reward is missing

Your streak follows the school week shown in your app. Weekends and school holidays pause it. You cannot pause it yourself, and support cannot restore a lost streak.

How do streaks work?

Where leagues are available, your leaderboard shows promotion and demotion zones. League sizes and level displays can differ. League positions do not award Pro, and Daily Quiz is unavailable.

XP leagues and the Daily Quiz

If Study Note appears in your AI chat, choose a topic to create an illustrated note. Some US students have this option during a test.

How do I create a study note in AI chat?

Voice Recall steps in your study plan ask you to explain a topic out loud. Tap Start learning, allow microphone access and tap Tap to answer. On the website it is being tested.

How do I use Voice Recall?

Upload allowances depend on your account and plan. Check the limit and refill time shown in your app. Documents can be up to 50 MB and 1,000 pages.

Limits for photos, files and messages in the AI chat

Classes keep chats, saved answers, study tools and uploads for one subject together. School accounts open them from the profile or the AI chat menu, and folders now ask you to move your content into a class.

What are classes and how do I use them?

Tell the AI what is wrong and ask it to rework the answer. Check important facts against your course material and report repeated problems.

The AI gave a wrong answer or answered in the wrong language

Create study tools from your notes or any upload in the AI chat. Here is where to find them, what the free plan includes for mock exams and what to do if generation gets stuck.

Flashcards, quizzes, mock exams and summaries

Create an exam study plan, switch between plans, share a plan or your timetable with a friend and add your timetable when it is available. Timetable imports can use up to seven photos.

Study plans and the timetable

Sign in at knowunity.com with the same account as in the app. Your library, AI chat and study tools stay in sync across devices.

Using Knowunity on a computer

Enter the activation code in your child's app to connect the subscription to their existing account. Create an account first if they do not have one.

How do I activate Pro for my child with an activation code?

The parent dashboard shows your child's study activity for the last seven days without personal details or chat content.

What can I see as a parent?

Ask to Buy and Family Link can block in-app purchases. Approve the purchase or buy on the website while your child is signed in.

Buying Pro for my child when the store blocks the purchase

Uploads are checked before they go public. You can edit a note while it is a draft or after it was rejected, and appeal a rejection once.

Uploading study notes and what happens after

Each upload has a Make public switch. Folders are private unless you share them. There is no single switch for the whole account.

How do I make my content private?

Report an upload, comment, profile or message from its menu. You can also block a user. Reports are reviewed by our moderation team.

How do I report content or a user?

If your upload was rejected or your account restricted, you can appeal once in the app or through the appeal form on our website.

Appealing a moderation decision

Apply on the creators page with your details, a social profile and a short talking video. Check WhatsApp for acceptance and email for application updates.

How do I join the creator programme?

Cash out your creator earnings from the payouts page on the website. Choose a payout method and request a payout once you reach the minimum.

Payouts for creators and content rewards

Use **Classes** to keep chats, study tools and uploads together by subject. You have one class per subject. Classes are for school accounts in the app. University accounts do not have Classes. If you do not see them on a school account, update the app.

## Find your classes

Open your profile and tap the **Classes** tab, or open **Classes** in the AI chat menu. Some students have only one of the two. This is being tested; you cannot choose, and support cannot change it.

The **Liked** items you saved before are now under **Settings**, in **Likes**.

## Add a class

- In Classes, tap **Add a class**, pick one or more subjects and confirm.
- If you have no classes yet, the app may show **Add your classes** when you open it.

You cannot add a second class for a subject you already have.

## Save to a class

Tap **Save** under an AI answer, a note, a quiz or a flashcard set. If the app is not sure which class it belongs to, it opens **Save to class** so you can choose.

## Upload your own material

1. Open the class and go to the **Saved** tab.
2. Tap **Upload**.
3. Choose **Take photo**, **Choose photo** or **Upload PDF**.

You can add up to 10 photos or PDFs at a time. Each PDF can have up to 50 pages. Split longer PDFs into smaller files.

## Find saved items

Scroll towards the top of the **Saved** tab to reveal **Search items**. Use the filter button to choose an item type.

## Folders are being replaced by Classes

In the app, folders now show **Folders will be discontinued.** Move what you need into a class:

1. Open the folder, or select it from your saved content on your profile.
2. Tap **Select Class** and choose a class.
3. Confirm the move. Tap **Open class** to see the saved items.

Your original content stays in the folder. The result tells you if any items are not supported by Classes.

## Remove items or delete a class

- To remove items, select them in the **Saved** tab and tap **Unsave**. You can undo this straight away.
- To delete a whole class, open the class settings and tap **Delete class**, then **Delete everything**. This deletes the files you saved in that class.

## Good to know

Classes are only in the app for now, not on the website. If something does not work, use the [support form](https://knowunity.com/support) under *A technical problem* and attach a screenshot.
