Terms of Service
Last updated: March 04, 2026
These Terms of Service ("Terms") govern your access to and use of the flashcard application and website available at https://penguen.io ("the App"), operated by penguen.io, 37 Mayne Road, Bowen Hills QLD 4006, Australia ("we", "us", or "our").
By creating an account or using the App in any way, you agree to these Terms. If you do not agree, do not use the App.
1. Eligibility
You must be at least 13 years old to use the App. By using the App, you confirm that you meet this requirement.
If you are under 18, you confirm that you have your parent's or guardian's permission to use the App and that they have read and agreed to these Terms on your behalf.
We do not knowingly allow children under 13 to create accounts. If we become aware that a user is under 13, we will close their account and delete their data.
2. Your Account
2.1 Registration
To use the full features of the App, you must create an account using a valid email address and a password. You agree to provide accurate and current information when registering and to keep it up to date.
2.2 Account Security
You are responsible for keeping your login credentials confidential and for all activity that occurs under your account. If you suspect unauthorised access, notify us immediately at support@penguen.io. We are not liable for losses resulting from unauthorised use of your account.
2.3 One Account per Person
You may not create multiple accounts to circumvent restrictions or bans.
2.4 Account Closure
You may close your account at any time by contacting us at support@penguen.io. On closure, your personal data will be handled in accordance with our Privacy Policy.
3. The Service
3.1 What We Provide
penguen.io provides a flashcard-based learning tool that allows you to create, store, organise, and study flashcard decks linked to your account.
3.2 Service Availability
We aim to keep the App available at all times but do not guarantee uninterrupted or error-free access. We may suspend or restrict access to carry out maintenance, improvements, or in response to a security incident.
3.3 Changes to the Service
We may add, modify, or remove features at any time. Where a change materially reduces the service you are paying for, we will provide reasonable notice and, where applicable, a prorated refund for unused subscription time.
3.4 Beta Features
From time to time we may offer features in beta or preview. These are provided as-is and may be changed or withdrawn without notice.
4. Subscriptions and Payments
4.1 Paid Plans
Some features of the App require a paid subscription. Current pricing is displayed on our website at https://penguen.io.
4.2 Payment Processor
All payments are processed by Lemon Squeezy (Lemon Squeezy, LLC), who acts as the merchant of record for all purchases. By completing a purchase, you also agree to Lemon Squeezy's terms of service and privacy policy.
4.3 Billing
Subscriptions are billed on a recurring basis (monthly or annually, depending on the plan you choose) until cancelled. By subscribing, you authorise Lemon Squeezy to charge your payment method at the start of each billing period.
4.4 Price Changes
We may change subscription prices with at least 30 days' notice. If you do not cancel before the price change takes effect, you will be charged at the new rate from your next billing date.
4.5 Cancellation
You may cancel your subscription at any time through your account settings or by contacting support@penguen.io. Cancellation takes effect at the end of the current billing period. You will retain access to paid features until that date.
4.6 Refunds
Because Lemon Squeezy acts as the merchant of record, refund requests are subject to Lemon Squeezy's refund policy. We will use reasonable efforts to assist you with legitimate refund requests. As a general policy, we offer refunds within 14 days of initial purchase if you have not made substantial use of the paid features. Recurring renewal charges are not refundable after they have been processed.
4.7 Taxes
Prices displayed may or may not include applicable taxes. Lemon Squeezy is responsible for calculating, collecting, and remitting applicable sales tax, GST, VAT, and similar taxes as the merchant of record.
