Frequently Asked Questions
You can access all services of ADT right after subscription. You can download 50 pages at a time.
After logging in , select Subscribe from the dropdown menu under your username. After selecting a subscription plan, you can pay with credit card through Braintree. We send you your electronic invoice via email when the payment is completed.
If you do not have a user account at us yet, please register. You can do it with your Facebook, Google, or eduID account, as well. If you register using your email address, an activation email will be sent as well.
We accept payments with bank cards through the globally approved service of Braintree. Should you encounter an issue with your payment? Contact us.
Yes, our prices include Value Added Tax (VAT).
No! Even though we will notify you before your subscription expires, you have to explicitly initiate renewal. This is for the sake of transparency and to avoid unexpected charges.
You can view your invoices, subscription status and extend your subscription at your Profile page. We recommend extending your subscription while it is active, because we offer discount prices for it.
If you have an active subscription, the extension starts after the expiry of your current subscription. Eg. if you have a half-year subscription expiring on the 30th of March and you subscribe for an extended half-year as early as the 10th of March, your new subscription will start from the 31st of March (after the current subscription expires). Thus you do not lose time by subscribing early, and can even have a discount for some plans, if you initiate extension while your current subscription is active.
