By creating an account, accessing, or using the Service, you agree to be bound by these Terms. If you are entering into these Terms on behalf of a company or other legal entity, you represent that you have the authority to bind such entity.

1. Description of Service

3. Beta Access and Testing

If you access or use any beta features, developer preview tiers, or testing database hosting services (collectively, "Beta Services"):

  • Provided Free-of-Charge: Beta Services are currently provided free of charge, solely for evaluation, testing, and development purposes.
  • No Reliability or Uptime Guarantees: We make absolutely no warranties or guarantees regarding the uptime, data reliability, data retention, database persistence, or availability of any Beta Services.
  • Termination and Deletion: We reserve the right to suspend or terminate your Beta Services access, delete your hosted databases, or permanently wipe stored user data at any time, for any reason, with or without prior notice.
  • Breaking Changes: We may deploy breaking API, schema, or configuration updates to Beta Services at any time without notice, which may require you to modify your applications or integrations.
  • Indemnification and Release of Liability: To the maximum extent permitted by applicable law, you agree to release Evokoa from any liability and defend, indemnify, and hold harmless Evokoa from and against any damages, liabilities, losses, or claims arising from your use of the Beta Services.
