Subscription terms
Version 2026-10-16 · Effective 16 October 2026. The simple rules for Mathidia Junior plans, billing and cancellation.
Who you are buying from
Mathidia Junior is operated and sold by ASM Professional Services, KVK Number: 42137630, VAT ID: NL005526019B33. Questions about billing, invoices or VAT can be sent to support@mathidiajunior.com. Prices are shown and charged in your detected country's local currency; where VAT applies it is calculated at checkout and shown on your invoice.
Your 3 free days
Every account gets one 3-day Free Trial, counted from the day that account first starts it. The Free Trial can only be used once per account and no card is required for it. The 3 free days belong to the Free Trial only — monthly, 3-month, 6-month and yearly plans include no free days and are billed from the day you subscribe.
Plans and trials
The plans, prices, included children and any free trial are shown on the pricing page before you pay. Only the Free Trial includes free days; when you choose a paid plan, your subscription starts on that day and you are billed from that day.
Billing
Paid plans renew automatically at the interval shown at checkout (monthly or yearly) until you cancel. Payment is handled by our payment provider; we never see or store your full card details.
Cancelling
You can cancel any time from your parent dashboard. Cancellation takes effect at the end of the current paid period — your children keep full access until then. There are no cancellation fees and no lock-in.
Refunds
If you believe you were charged in error, contact us through your account and we will review it. Where consumer law in your country gives you a right of withdrawal or refund, these terms never reduce those rights.
When a subscription ends
If a paid plan lapses, child profiles and their progress are kept safe but learning sessions are paused until you re-subscribe or delete the profiles. Your data is never deleted automatically just because a subscription ends — deletion only happens when you ask for it. See the data deletion page.
Price changes
If we change a plan's price we will notify the account email in advance; the new price only applies from your next renewal after that notice.
