Pro, on your terms.
Three calendar months to explore. Monthly billing afterwards.
€199 / month
Starting price for one Pro account, plus applicable tax. No annual commitment. Free remains €0 with no expiry.
How the three-month trial works
- Sign in, review the renewal terms, and enter your card details in secure Stripe Checkout.
- No subscription charge for at least three calendar months after you complete signup. Checkout displays the exact trial end and first billing date.
- At trial end, your subscription renews automatically at €199 per month, plus applicable tax, until canceled.
- To avoid the first charge, cancel before the trial ends in Account → Manage billing. After paid renewal, cancellation stops the next renewal and access continues to the end of the paid period.
One subscription trial per account. No catch-up charge for the free months, setup fee or annual prepayment. A card issuer may show a temporary card-verification authorization; it is not a Lemonergy subscription charge. Stripe handles card numbers and security codes; Lemonergy does not receive or store them.
Existing card-free complimentary grants keep their original expiry and never convert to paid subscriptions automatically. Choosing a new subscription requires separate consent.
