03Maintenance · 40% when you choose

Your licence never expires.
Only updates do.

Updates after the first year: renew maintenance for 40% of the then-current list price — USD 599 (Professional) / USD 1,599 (Enterprise), one-time. Renew early for a discount. Your licence never expires; only updates do.

There is no auto-renewal and no subscription. We email you at 60, 30, and 7 days before your update window closes, with a one-click renewal link — and if you skip a year, nothing breaks: the version you have keeps working, licensed and watermark-free, forever.

04FAQ · the fine print, in plain words

Questions we would ask too.

What does “per legal entity” actually mean?

One licence covers one legal entity — every developer, server, CI runner, and internal product inside it. There are no seat tiers, headcount bands, or per-server counts anywhere in our price list. Enterprise widens the unit to a corporate group: the parent and its affiliates are covered by one licence.

What do “SaaS” and “OEM” included mean?

You may run Rendlio inside your own SaaS and ship it embedded (OEM) in your product, at no extra fee — the licence price is the whole price. One boundary: building a product whose main job is conversion itself (a third-party converter) requires the Enterprise licence, which carries that right explicitly.

What happens after my 12 months of updates run out?

Nothing. Your licence is perpetual: the last version your maintenance covers keeps working forever, fully licensed. When you want newer versions, renew maintenance for 40% of the then-current list price — one-time, whenever you choose. We remind you at T-60/30/7 by email; we never auto-charge.

Why can’t I buy Professional or Enterprise today?

Because the engine is pre-launch, and we don’t sell what hasn’t shipped. Professional and Enterprise go on sale at GA — at exactly the prices published on this page, locked from day one. The Founding licence is the way to buy in now: $1,000, credited toward Professional at GA.

What protects Founding buyers if the project never reaches GA?

The founding terms carry a kill clause: if Rendlio is discontinued before GA, you choose a full refund — or you keep a perpetual, unsupported build plus committed delivery of the source code. Either way, you are never left with nothing.

What is the refund policy?

30-day money-back, handled by Paddle — the policy. One honest consequence of our zero-phone-home architecture: we cannot reach into your machines to disable anything, so a refund marks the licence revoked in our records and the terms oblige you to stop using it. We accept that trade-off; your privacy is worth more than our enforcement.

Who is the seller?

The Rendlio Association (Verein Rendlio), a Swiss non-profit — 100% of profits go to charity. Paddle.com acts as merchant of record: it handles payment, VAT, and invoicing. Enter your VAT ID at checkout for reverse-charge invoicing.
