Describe Licences and seats
What a licence is
A licence is what unlocks the software for your organisation. DynDyn.Pdf issues it, it's tied to your organisation, and it carries an edition, an expiry, and a number of seats. Your organisation's Owner or Admin manages it from the Licences screen.
When a licence is generated or re-issued, the portal shows you the licence key once, in full. Copy it somewhere safe straight away — afterwards the portal only keeps a fingerprint of it, not the key itself, so it can't show it to you again.
Editions
| Edition | What it's for |
|---|---|
| Community | Free. No subscription needed. |
| Evaluation | A time-limited trial with full features. Your organisation can generate exactly one of these, ever, from the Licences screen — Owner or Admin only. |
| Starter | Paid, self-serve. Started from the Billing screen. |
| Pro | Paid, self-serve. Started from the Billing screen. |
| Enterprise | Paid, arranged directly with DynDyn.Pdf's sales team rather than self-serve checkout. |
Seats and activations
A seat is how many computers can use your licence at the same time — it's a number set on the licence itself. An activation is one computer's claim on one of those seats: install the software on a machine and activate it, and that machine counts against your seat total until it's deactivated.
Reinstalling on the same machine doesn't cost you a new seat — DynDyn.Pdf recognises it as a machine it already knows.
Everything is managed from the Activations screen, visible to Owner, Admin and Developer roles; deactivating a machine is an Owner or Admin action.
When you run out of seats
Activating a new machine once every seat is already in use is refused, with a message telling you how many are in use out of how many you have. To free one up, deactivate a machine you're no longer using, or ask your Owner or Admin to add seats — upgrade your subscription, or contact sales for Enterprise.
Moving a licence to a new machine
Deactivate the old machine from the Activations screen, then activate the software on the new one — it will take the seat that's now free. You can do this up to three times per licence within any rolling twelve months, so plan machine changes rather than doing them casually.
Expiry and renewal
Every licence has an expiry date, shown on the Licences screen. An expired licence keeps working for a further 30 days — a grace window, so a renewal that arrives late never stops your production run. After those 30 days the software falls back to the free feature set until the licence is renewed.
- A licence tied to a subscription (Starter, Pro, Enterprise) renews automatically each billing period as long as the subscription stays active, and updates in place — you don't need to reactivate machines that are already running. If the subscription is cancelled, the licence is allowed to run to the end of the period it already paid for, rather than stopping immediately.
- An Evaluation licence is one-time and time-limited. It isn't renewed — move to a paid edition before, or as soon as, it expires.
- An Owner or Admin can also revoke a licence outright, with a reason, from the Licences screen — for example if a key was exposed.
