Classerium accepts Visa, Mastercard, Diners Club, and American Express.
Whether you are paying for the Premium plan with a new account or are upgrading an existing Free account, you can make payments from your account page. This is also where you can check your account balance, view the current plan, or unsubscribe at any time. You must be logged in to view your account page.
How it works
Your Premium plan will charge your card automatically (yearly or monthly, according to your payment choice) or you may refill your balance using prepaid system. There are no refunds for unused amounts, even if you pre-pay for a subscription then unsubscribe early.
- Your account balance has changed or fallen below $9.75
- Your plan has changed
- You subscribe or unsubscribe to premium
- A premium subscription payment is coming soon
- Your bank has denied a premium subscription payment
You are safe
Classerium processes payments via STRIPE with a PCI DSS 3.0 security standard. Card details are 256-bit SSL encrypted. Transactions pass 3D Secure.
Classerium never saves card details and it's impossible to move money from a Classerium account so hacking Classerium is unlikely, but we do recommend you use a strong password (with at least six characters combining letters, numbers, and characters) to protect your personal details, such as name and email address.
Reminder: Classerium can't protect your computer from spyware. Watch out.
If you suspect fraudulent activity on your card, contact your bank immediately. If you have a question about plans, subscriptions, or payments, please contact Classerium support at firstname.lastname@example.org.
