Agreement
These terms of service are between you and Berman Digital Ltd, an Ontario, Canada company. They apply to Chart Kit websites, documentation, checkout pages, support, license certificate services, free packages, paid Chart Kit Pro products, and any related services that link to these terms.
By using the services, purchasing a license, or installing a paid Chart Kit Pro package for production use, you agree to these terms. If you use Chart Kit on behalf of a company, you represent that you have authority to bind that company.
Questions about these terms can be sent to[email protected]. Privacy questions can be sent to[email protected].
Products and licenses
The public react-native-chart-kit package is licensed under its MIT license. These terms do not reduce the rights granted by that open source license.
Chart Kit Pro, including @chart-kit/pro and Pro-only packages, is commercial software. Pro use is governed by the Chart Kit Pro Commercial License included with the Pro package, your applicable Polar order or subscription terms, and any separate written agreement signed by Berman Digital Ltd. If a separate written agreement conflicts with these terms, the written agreement controls for that conflict.
Pro packages may be publicly installable for evaluation. You may install and test Pro packages internally without buying first, but production use, customer-facing use, commercial deployment, or distribution in an application requires an active paid or written Chart Kit Pro license.
Paid plans
Chart Kit Pro is currently sold as an annual subscription. Plan scope is shown on the pricing page, checkout page, receipt, license certificate, or written order. Current self-serve plans are:
| Plan | Scope | Price |
|---|---|---|
| Solo | 1 developer, 1 production app, revenue or funding cap of $250k. | $49 / year |
| Startup | Up to 3 developers, 1 production app, revenue or funding cap of $2M. | $149 / year |
| Business | Up to 6 developers, up to 2 production apps, no revenue or funding cap. | $499 / year |
| Enterprise | Custom scope for larger teams, multiple products, purchasing workflows, or custom terms. | Custom |
Prices, plan names, features, and limits may change for future purchases or renewals. The checkout page or written order controls the amount due for a purchase. Taxes may be added where required.
Checkout, renewals, and cancellations
Self-serve checkout is handled by Polar. Polar may collect payment, billing, tax, customer, and subscription information under its own terms and privacy policy.
Unless your order says otherwise, a paid Pro subscription runs for one year from the purchase date, subscription start date, or renewal date. Renewal requires successful payment or separate written authorization. If payment fails, is canceled, is refunded, or the term expires, the Pro license may become inactive, expired, revoked, or otherwise limited.
You are responsible for choosing the correct plan for your developer count, production application count, company size, and distribution model. Contact [email protected] before purchase if your use needs Enterprise, OEM, embedded, white-label, affiliate, resale, or customer-distributed rights.
Refunds
You may request a refund for any reason within 30 days after purchase. Refund requests should be sent to[email protected] or handled through the applicable Polar support flow.
If a refund is issued, you may not keep using Chart Kit Pro under the refunded license. You must stop production use, remove Pro from active development and deployment workflows, and delete copies under your control unless a separate active license or written authorization covers that use. Refunded license keys and certificates may be revoked or marked inactive.
Use restrictions
You must not:
- use Chart Kit Pro beyond the plan limits or term that apply to your order;
- redistribute, sell, sublicense, publish, rent, lease, or share Pro as a standalone package, library, toolkit, repository, or source distribution;
- make Pro available in a way that lets third parties extract, copy, install, or use it independently of your application;
- use Pro to build a competing charting library, charting toolkit, or charting component framework;
- remove proprietary notices, license notices, or copyright notices;
- interfere with the website, checkout, license certificate service, or support systems;
- attempt to bypass license, access, security, rate-limit, or abuse-prevention controls;
- upload malicious code, secrets, payment data, or unlawful content through support or contact channels.
Support and updates
Support is provided by email unless your order says otherwise. Solo and Startup currently include standard email support. Business currently includes priority email support. Enterprise support is controlled by the written order or agreement.
Support does not include guaranteed response times, custom feature work, emergency coverage, implementation services, or compatibility with every third-party dependency unless those commitments are stated in writing. Updates, fixes, and package availability may change during the normal development of the product.
Ownership and feedback
Berman Digital Ltd and its licensors retain all rights in Chart Kit Pro, the Chart Kit websites, documentation, branding, and commercial materials. You retain rights in your applications, data, and content.
If you send suggestions, feature requests, bug reports, or other feedback, Berman Digital Ltd may use that feedback without restriction or obligation to you.
Third-party services
The services may depend on third-party platforms, including Cloudflare, Polar, Google Analytics, npm, GitHub, React, React Native, and related package ecosystems. Third-party services are governed by their own terms and privacy practices. Berman Digital Ltd is not responsible for third party services that it does not control.

To the maximum extent permitted by law, Berman Digital Ltd will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, business interruption, or costs of substitute goods or services, arising out of or related to the services or these terms, even if advised of the possibility of those damages.
To the maximum extent permitted by law, Berman Digital Ltd's total aggregate liability arising out of or related to the services, these terms, or any applicable order will not exceed the amounts you paid to Berman Digital Ltd for the relevant Chart Kit product during the 12 months immediately before the event giving rise to the claim, or USD $100 if no amounts were paid. This section does not limit liability that cannot be limited by law.
Indemnity

Termination
You may stop using the services at any time. Berman Digital Ltd may suspend or terminate access to paid services, support, license certificates, downloads, or related systems if you breach these terms, fail to pay, exceed your license scope, create legal or security risk, or misuse the services.
Sections that by their nature should survive termination will survive, including ownership, restrictions, warranty disclaimers, limitation of liability, indemnity, governing law, and payment obligations.
Governing law
These terms are governed by the laws of Ontario, Canada and the federal laws of Canada that apply there, without regard to conflict of law rules. Unless applicable law requires otherwise, disputes will be brought in the courts located in Ontario, Canada.
