Frequently asked questions

VAT, slider mechanics, refunds, and the details people ask about before they pull out a card.

Why are prices in USD when you're based in Europe?
Polar.sh — our merchant of record — charges in USD because the global SaaS market expects USD. They convert into your local currency at checkout. We're paid out in EUR after their fee and the FX conversion, which is also why the listed prices include a small premium over a pure EUR-pricing equivalent. Predictable for you, FX-resilient for us.
Will I be charged VAT?
If you're billing from a country that requires VAT collection (EU, UK, Australia, and several others), Polar.sh adds VAT at the published rate at checkout. You see the full breakdown — subtotal, VAT, total — before paying, and your invoice itemizes it for accounting. Customers outside VAT regions pay just the listed price.
How does the Pro slider work?
$1.50 per monitor per month, anywhere from 10 to 100 monitors. Drag the slider to your number, the price recalculates instantly. So 13 monitors is $19.50/mo, 27 is $40.50/mo, 100 is $150/mo. There are no monitor 'tiers' or surprise step changes — it's pure per-seat. Annual pricing is the same formula times 10 (giving you 2 free months versus paying monthly).
Can I change tiers or monitor count later?
Yes, anytime, via the Polar.sh customer portal accessible from your billing page. Polar handles proration automatically — upgrade mid-cycle and you're billed for the difference; downgrade and the credit applies to the next cycle.
What happens if my payment fails?
Polar retries automatically per their dunning schedule. We mark the subscription past_due in Convex but keep monitors running through the standard retry window. If retries fail through the cutoff, monitors pause and you can reactivate by updating the card.
Can I cancel anytime?
Yes. Cancel from the Polar.sh customer portal — no email needed, no retention call. Monitors run through the end of the current period you've already paid for, then pause. Account data stays around 30 days in case you change your mind, then deletes automatically (GDPR-aligned).
Do you offer refunds?
Yes — within 14 days of payment, no questions asked. Reply to any email we've sent you, or use the contact form, and we'll refund the most recent charge. Beyond 14 days we generally don't refund, but reach out if you've been charged for service we couldn't deliver and we'll make it right.
Is there a discount for annual billing?
Yes, two months free — pay 10× the monthly rate for a year of service instead of 12×. Same for Starter ($60/year vs $72) and Pro ($150/year at 10 monitors vs $180, scaling linearly).
