1. Grant of License

Xplat-soft s.r.o. grants you a non-exclusive, non-transferable, limited license to use the "Universal Sign In" version of @react-native-google-signin/google-signin package ("RNGS") in accordance with the terms of this license.

In the case of Personal License, the license grants permission for one individual to access and use RNGS. In the case of Team License, the license grants permission for several (as indicated by the subscription plan on our website) individuals (employees and contractors of the business entity) to access and use RNGS.

The Seats are not to be reassigned to different users during the subscription period without explicit permission from the Licensor.

2. Definitions

  • "Licensee" refers to any individual or business entity who has purchased a license.
  • "RNGS" (also "Software") refers to the source code, compiled binaries, CLI Tools, and other resources made available to the Licensee after purchasing a RNGS license.
  • "Product" refers to any artifact produced that incorporates RNGS or derivatives of RNGS.
  • "Employee" refers to any individual employed by the Licensee on a full-time or part-time basis.
  • "Contractor" refers to any individual or business entity contracted to perform services for the Licensee.
  • "Seats" refers to the number of individuals who are authorized to use RNGS under the respective license. The number of seats is given by the subscription plan.

3. Scope of License

This license permits the Licensee to use Software in an unlimited number of Products, including those of a commercial nature. This right extends to Employees and Contractors of the Licensee for work directly related to the Licensee's projects.

4. Restrictions

The Licensee shall not:

  • Re-sell or re-distribute RNGS, in whole or in part, to any third party.
  • Create a service that allows third parties to use RNGS to build a Product.
  • Grant access to RNGS to individuals who are not an Employee or Contractor of the Licensee.
  • Develop or distribute a code template, starter kit, library, or similar developer resource that includes RNGS.
  • Circumvent, disable, or tamper with authentication mechanisms in CLI Tools.
  • Share authentication credentials with non-authorized individuals.

5. Termination

  • The license is valid as long as the Licensee maintains their subscription (pays a subscription fee) with the Licensor. Upon termination of the subscription, the Licensee loses the access to private npm registry where package is hosted. They also lose the right to receive updates, new versions, or additional materials related to RNGS. However, if the Licensee was in full compliance with this License during the subscription period, Licensee retains the right to continue using the version of RNGS they obtained before their subscription ended. Licensee, at their sole responsibility, needs to ensure they keep a copy of RNGS for use after the subscription ends.
  • This continuing right is non-transferable and is limited to the Licensee's internal business use, including use by the Licensee's Employees and Contractors.
  • The Licensor reserves the right to revoke this continuing right from any Licensee in the event of misuse of RNGS as detailed in the Restrictions section of this license or breach of any other terms of this license.
  • License duration is one year unless indicated differently at the payment portal.
  • The Licensor may, at its discretion, suspend or revoke access to the Software or related services if it reasonably suspects a violation of this License, pending investigation or resolution. Such past violations do not prevent the Licensee from purchasing a new license or continuing use under a new subscription, provided the license terms are met.
  • If this License is terminated due to breach by the Licensee, the Licensee must immediately cease all use of RNGS, delete all copies in their possession or control, and, if requested by the Licensor, certify in writing that they have done so. Licensee may not rely on any continuing rights described above.

6. No Warranty

The Software is provided "as is", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. Licensor hereby disclaims any warranty that the Software shall be error free, without defects or code which may cause damage to Licensee's computers, Licensee's software, or to the Licensee, and that Software shall be functional. Nothing in this Grant of License shall require the Licensor to provide the Licensee with support or fixes to any bug, failure, performance issue, or other defect in the Software.

7. Limitation of Liability

In no event shall the Licensor be liable for any claim, damages, or other liability arising from the use of RNGS, whether in an action of contract, tort, or otherwise. The Licensor shall not be liable for any failure or delay in performance caused by circumstances beyond its reasonable control, including but not limited to acts of God, natural disasters, labor disputes, or interruptions of internet infrastructure or the package registry through which the package is distributed. Licensee shall be solely liable to any damage, defect or loss incurred as a result of operating the Software and undertake the risks contained in running the Software.

8. Governing Law, Jurisdiction

This license shall be governed by the laws of the Czech Republic, without regard to its conflict of law provisions. The courts of the Czech Republic shall have non-exclusive jurisdiction to settle any dispute or claim arising out of or in connection with this license.

9. Support and Updates

Licensor may provide Licensee from time to time with package updates and fixes, according to the Licensor's sole discretion.

The Software is provided without any guaranteed support, updates, or maintenance. CLI Tools may receive updates independently of the main RNGS package.

10. Assignment

This license and the rights granted hereunder may not be transferred or assigned by the Licensee without the Licensor's prior written consent. However, if the Licensee undergoes a change of control, merger, or acquisition, the acquiring entity must obtain a new license or negotiate terms with the Licensor.

The Licensor may, at their sole discretion, waive the licensing fee for RNGS and grant a license with a number of Seats that may differ from the standard plans. Such license is governed by the Team license rules. This may be the case especially for individuals maintaining major Open Source Software packages. Licenses granted free of charge are still subject to the other terms set out in this license. Although unlikely, the Licensor at their sole discretion may require free licenses to convert to paid licenses at the then-current rates, with 21 days notice sent via email. The Licensee must then either pay the license fee or remove RNGS from their Products, cease all use and, if requested by the Licensor, certify in writing that they have done so.

11. CLI Tools

CLI Tools included in the Software (such as @react-native-google-signin/config-doctor) require an active subscription for operation. CLI Tools may:

  • Validate subscription status via remote authentication services
  • Process local development files (APKs) necessary for the CLI tool functionality
  • Collect usage analytics for service improvement in accordance with the Licensor’s Privacy Policy.

12. Survival

Sections 4 (Restrictions), 5 (Termination), 6 (No Warranty), 7 (Limitation of Liability), 8 (Governing Law, Jurisdiction), and this Section 12 shall survive any termination or expiration of this License.
