Term vs perpetual: how long a data licence lasts
A term licence grants use for a fixed period (commonly a set number of years) after which rights revert and delivered data must be deleted or returned per the contract; a perpetual licence grants use that does not expire. Perpetual costs more because the buyer is pricing forever-use — and the owner is giving up every future licence of the same records to that buyer.

What to pin down in writing
- Duration + renewal: fixed years, auto-renewal, or perpetual — one clause, no ambiguity.
- Trained-model reality: a term can end the right to use the data; what happens to models already trained on it is a separate clause and must be negotiated explicitly — do not assume deletion of data deletes learned patterns.
- Delivery copies: retention, backups and deletion certification at term end.
- Price step: if a buyer asks to extend or convert to perpetual later, is the price mechanism agreed now?
How duration moves price
Duration is one of three price levers, alongside scope and exclusivity. Published market analysis puts wide, long, exclusive packages at multiples of narrow, short, non-exclusive ones — which is why comparing the terms of two offers matters as much as comparing the two numbers. A lower perpetual offer can be a worse deal than a higher term offer you can re-license.
Not sure which term fits your records?
That is a fit-check conversation, and it costs nothing.
