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. Cancel a free trial before it ends to avoid the yearly charge.

How do I cancel my Knowunity Pro subscription?

Messages such as Prices didn't load, This Purchase Isn't Allowed or The App Store isn't responding explain why a purchase in the app did not go through. Here is what each one means and what to do next.

What do the error messages when buying Pro in the app mean?

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 a renewal payment fails, update your payment method; Pro returns once the store collects it.

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. A first-year offer or a free trial turns into the full yearly price.

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. Family plans and Pro Duo are not on sale, but plans that already exist keep working. Website purchases can be moved to another account by support.

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

No. A phone number is never required. Some students are asked for one during setup or when they open the app, as part of a test; tap Skip or Not now to continue without one.

Do I have to add a phone number during setup?

If the website offers notifications, choose Enable notifications and allow them in your browser. You can skip them or turn them off in site settings.

How do I manage browser notifications?

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

If you close the app before finishing setup, Knowunity takes you back to the step where you stopped. Continue, tap Exit when shown, or start over before you create your account. You do not need another account.

Why does setup reappear when I open the app?

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 you can use the same email again once the deletion is complete.

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?

Some students can choose Light, Dark or System in the app's settings while a light design is tested. Everyone else, and the web app, keep the dark design.

Can I use Knowunity in light mode?

Change your studies in Settings under Account settings. If your year is missing, change the school type first. After a new school year starts, the app may ask whether you are still in your year.

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, and weekends and school holidays pause it. Freezes refill each school week and you can earn more by finishing activities. Some students can win a lost streak back with a quiz.

How do streaks work?

Leagues run from Monday midday to Sunday evening. Your leaderboard shows promotion and demotion zones, and results appear after a short break. League positions do not award Pro, and Daily Quiz has been removed.

What are classes and how do I use them?

Some accounts see memory notices and a Memory switch in AI chat. Tap a notice to read what Knowie remembers. These controls are being tested, and turning memory off does not delete your account.

Why does AI chat show memory notices?

Why do the AI chat buttons look different?

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 from its menu, or a profile from the profile menu. Choose a reason, say why and submit. You can also block a user from their profile.

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.

Payouts for creators and content rewards

Some students see **memory loading...** or **Memory updated** in AI chat. These notices are being tested. Other accounts can have personalised conversations without seeing the notices. You cannot opt in or out of the test, and support cannot switch the notices on.

## What the notices mean

The notices show that Knowie is loading or updating information used for personalisation. They are not a request for you to upload another file.

**Memory updated** can appear again from time to time while you chat, not only in your first conversations.

Tap a notice to open **About Memory**, which explains what Knowie remembers about you. Tap **Got it** to close it.

If you want an answer to use different information, explain the correction in your message. Check important answers against your course material.

## The Memory switch

Students who see the notices also have a **Memory** switch in the attachment or tools panel. Open that panel and tap the switch to change the personalisation settings it controls. Other accounts do not have this shortcut. When memory is turned off, the notices do not appear.

Turning this switch off is not an account-deletion request. Do not use it as a way to delete your account or its chat history. See *How do I delete my account?* for account deletion.

## Something looks wrong

If a notice stays on screen or personalisation seems incorrect, update the app and try again. Use the [support form](https://knowunity.com/support) under *AI or content quality* if the problem continues. Include the notice and a screenshot, without sharing information you do not want support to see.
