Core tools stay free

No. Every PDF and Markdown operation runs inside your browser using WebAssembly. Document bytes are not sent to a server for processing, on any plan — free or paid.
No. Core workflows in every listed PDF tool and everyday Markdown publishing work with no sign-up, email address, or card. A verified account is required only when you buy or use a Day Pass or Pro capability.
There is no daily task quota or commercial upload quota, because document processing stays local. Each tool still applies explicit safety limits where needed, and practical capacity depends on your device memory.
No. Exports contain your content only — Lemmafour does not add branding, marks, or metadata advertising the tool.
Every file you already exported is yours permanently and is unaffected. The workspace returns to the free feature set; your documents stay on your device either way.
The 24 hours begin when you first activate the purchase, not when you pay, and activation must happen within 30 days of payment. Returning during those 24 hours restores the remaining time rather than restarting it.
Paddle.com is the authorized reseller and Merchant of Record. Paddle handles payment details, applicable tax, invoicing, and payment-related buyer support. Lemmafour never receives your card details.
Yes. An initial paid purchase can be refunded in full within 30 days, with no reason required. See the refund policy for the full terms.
Monthly and annual subscriptions renew automatically until canceled. Cancellation takes effect at the end of the current paid period. The Day Pass is a one-time purchase and never renews. Taxes, when applicable, are calculated by Paddle at checkout.
