Bound to one or more named developers within a single legal entity. Worldwide deployment by the licensee.
Enterprise basis
Enterprise
Unlimited developers across a single corporate group (parent and wholly-owned subsidiaries).
Application basis
Application

What's included
- 1 named developer
- Unlimited slides per presentation
- Commercial use in your products
- 1 year of version updates
- Priority email support
Restrictions
- License is bound to ONE named individual — sharing seats across teammates is not permitted.

- Removal of a developer is permitted without notice; adding a developer beyond the seat count requires purchasing additional seats or upgrading to Enterprise.

Description
For small teams and startups of up to 10 developers working on shared codebases. Every team member can use NetCorePpt across unlimited projects and repositories. Ideal for growing engineering teams that need consistent tooling, shared CI/CD pipelines, and a single procurement point.

Section 4.0
Pricing & Renewal
The price of every paid tier is listed in §2 above and confirmed on the invoice issued at the time of purchase. All prices are exclusive of any applicable taxes, which are calculated at checkout based on the buyer's billing address.
Renewal
License terms renew annually. Renewal can be turned off at any time from your account dashboard. If the license expires without renewal, the library can no longer be used until it is renewed.
Upgrades
To upgrade from any tier to a higher tier (for example, Single User → Ten User, or Ten User → Enterprise), you pay only the pro-rated difference for the remainder of the current term. Contact sales to request an upgrade.
Refunds
Within 7 days of the original purchase, you may request a full refund by contacting sales. After 7 days, refunds are not available, but downgrade and upgrade options remain as described above.
Regional pricing
The same tier is priced in either USD or CNY. The currency presented at checkout is determined by your billing country; the underlying feature set and restrictions are identical across currencies.
Section 5.0
Support
Email support
All paid tiers include email support with a 1-business-day response target on weekdays. Bug reports are prioritized and typically patched within a release cycle.
Dedicated channel
Enterprise tier includes a dedicated support channel with direct access to the maintainers, plus priority bug fixes.
Free first year
Email support is free for all paid customers for one year from the date of purchase. After the first year, Single User and Ten User licenses can be renewed together with the license term to continue support.
Section 6.0
Liability
In no event shall NetCorePpt's liability to you (whether in contract, tort, or otherwise) exceed the license fee paid by you for the Software. This limitation does not apply where applicable law prohibits such limitations.
