Definitions
- Error — a failure, outage, lack of operation, or incorrect operation of the Platform or any of its features, resulting in the Platform not performing as intended. Errors are categorized as critical, high, normal, or low priority, as detailed in the Service Level Agreement (SLA) annex.
- Service Level Objective (SLO) — the percentage of uptime the Platform is expected to achieve, depending on the Plan chosen by the Client.
- Maintenance Time — the period between the proper submission of a Ticket, the Initial Response Time, and completion of the Maintenance.
- Initial Response Time — the time in which the Platform Operator receives a Ticket, verifies its validity, categorizes the Error and its priority, and responds with an estimated Maintenance Time.
- Downtime — more than a one-percent Error Rate.
- Business Days — Monday through Friday, excluding public holidays in Poland.
- Business Hours — the hours during which Support is available on Business Days, depending on the Client’s Plan:
- a) 8x5 — 9:00 AM to 5:00 PM (UTC+02:00);
- b) 12x5 — 7:00 AM to 7:00 PM (UTC+02:00);
- c) 24x7 — an optional service available 24 hours a day, seven days a week.
- Monthly Uptime Percentage (Availability) — a metric defining the Platform’s actual usability by Clients, calculated as the total number of minutes in a month minus the number of minutes of Scheduled Maintenance and Downtime, divided by the total number of minutes in that month.
- Support Unit — the division of the Platform Operator responsible for providing Support for the Platform and Services. The Support Policy is an annex to these Terms and Conditions.
- Client — a person or entity using the Platform under a Client Account.
- Client Account — access to the Platform for the Client following Registration. Access to specific functionality is granted after purchasing a Plan.
- Platform Credits — credits available to the Client when the Monthly Uptime Percentage falls below the Service Level Objective. The percentage of the monthly bill not meeting the SLO is added as credits that may be used for upgrades, increased limits, or future monthly invoices. Platform Credits are non-transferable, non-refundable, and may be used only for RevoEngine Services.
- Maintenance — resolution of an Error in a manner that restores proper functioning in the affected area, or routine maintenance of the Platform. Maintenance is categorized as:
- a) Emergency Maintenance — critical maintenance that must be performed as soon as possible because of a critical Platform issue or total unavailability;
- b) Scheduled Maintenance — routine Platform maintenance planned with at least two days’ notice and which may lead to Downtime.
- Negotiations — the process of establishing cooperation terms between the Platform Operator and an entity intending to become a Client using the Plus, Business, or Enterprise Plan.
- Downtime Period — a period of one or more consecutive minutes of Downtime. Partial minutes or intermittent Downtime lasting less than one minute are not counted toward a Downtime Period.
- Billing Period — the billing period for the Client Account Agreement, lasting one calendar month.
- Platform Operator — REVONG MAREK POTARGOWICZ spółka komandytowa, with its registered office at ul. Rakowska 16/130, 02-237 Warsaw, Poland, entered in the Register of Entrepreneurs maintained by the District Court for the Capital City of Warsaw in Warsaw, XIV Commercial Division of the National Court Register, KRS 0001010291, NIP 5223245103, operating the RevoEngine Platform.
- Terms and Conditions — these Cloud Services and Support Terms and Conditions.
- Platform Terms and Conditions — the terms defining the general conditions for using Services provided through the RevoEngine Platform.
- Registration — the process of creating a Client Account by providing the required information, accepting the Terms and Conditions and Privacy Policy, and activating the Client Account as described in the Platform Terms and Conditions.
- Plan — the type of access to functionality within the Client Account, reflecting the level of Services provided by the Platform Operator. Available Cloud Services Plans are Start, Standard, Plus, Business, and Enterprise.
- Platform — the online RevoEngine technology platform operated by the Platform Operator, available at revong.com, providing Cloud Services within a contracted instance.
- Retry Policy — the Client sending a Valid Unit must wait before resending a request after an Error. The minimum wait is one second for each consecutive Error, increasing exponentially up to 30 seconds.
- Valid Unit — a synchronous unit such as an API request, an asynchronous unit triggered by an Event or Schedule available within the Platform, or a WebSocket operation that complies with the documentation and would normally result in a non-error response or status.
- Force Majeure — an external event independent of the Platform Operator, unforeseeable and unavoidable, occurring after the Client Account Agreement takes effect and the Client receives access to Services.
- Subaccount — a collection of data associated with a specific Subuser, including information provided by the Client and Subuser during their use of the Platform and information about their Platform activity. A Subaccount forms part of the Client Account.
- Subuser — a person using the Platform after logging in to a Subaccount, in particular an Employee of the Client or a person invited by the Client to use Cloud Services within the contracted instance assigned to the Client’s Plan.
- Services — the services provided or made available by the Platform Operator using the Platform, including Cloud Services and Support Services.
- Cloud Services — access to a tool enabling Clients to store, process, analyze, and share data and to design client applications in a cloud environment. The Platform provides infrastructure, including servers, disk space, computational resources, and an execution environment in which Clients can create applications using components available on the Platform.
- Error Rate — the number of Valid Units that could not be processed successfully, for example synchronous Platform API or Endpoint requests returning HTTP status 5XX, except reserved Endpoint status 502, or asynchronous units that finished with an error, subject to a minimum of 100 Valid Units in the measurement period. Synchronous sequential requests do not count toward the Error Rate when unit processing duration is greater than 60 seconds unless they conform to the Retry Policy.
- Support — Maintenance and service support provided by the Support Unit.
- Ticket — a report successfully submitted by the Client through the online ticketing system.
