DARTASTIC TERMS OF SERVICE

Last updated: 20 May 2026

Provider: Dartastic.io ("Dartastic", "we", "us", "our").

These Terms of Service (the "Terms") govern your access to and use of the Dartastic website, accounts, private package registry (pub.dartastic.io), Symbolizer, hosted observability services, paid software, and related services (collectively, the "Service"). By creating an account or using the Service, you agree to these Terms. If you use the Service for an organization, you represent that you may bind it, and "you" includes that organization.

  1. THE OFFERINGS

Dartastic provides three distinct kinds of offerings, governed as follows:

(a) Open-source SDKs — dartastic_opentelemetry_api, dartastic_opentelemetry, flutterrific_opentelemetry, and similar packages published publicly under the Apache License 2.0. These are governed by their own open-source license, not by these Terms, and require no account or fee. See OPEN-SOURCE-LICENSING.md. (b) Dartastic Pro software — proprietary Dart/Flutter packages and the native runtime engine distributed via pub.dartastic.io under subscription. Use of the Pro software is governed by the Commercial License, which is incorporated into these Terms by reference. (c) Hosted and managed services — the private package registry, Symbolizer, and single-tenant Dartastic Hosted observability clusters. Use of Dartastic Hosted is additionally governed by the Hosted Services Agreement.

If a conflict exists, the Commercial License or Hosted Services Agreement controls for its subject matter; otherwise these Terms control.

  1. ACCOUNTS

You must provide accurate, current, and complete registration information and keep it updated. You are responsible for safeguarding your credentials and for all activity under your account. Notify us promptly at security@dartastic.io of any unauthorized use.

  1. SUBSCRIPTIONS, FEES, AND TAXES

Paid offerings are sold by tier on a per-seat or per-cluster basis as described at https://dartastic.io/pricing and in your order or self-service checkout (the "Order"). Fees, included quantities (such as Symbolizer call quotas), and overage rates are those stated in the Order; the Order and the pricing page are the source of truth, and the specific numbers are intentionally not restated in these Terms so that they cannot drift. Unless the Order says otherwise: subscriptions renew automatically for successive terms; fees are charged in advance; fees are exclusive of taxes, which you are responsible for; and you authorize us and our payment processor to charge your payment method.

  1. SERVICE-, TIER-, AND RUNTIME-DEPENDENT CAPABILITIES

Features and included services vary by offering, tier, build flavor, platform, and configuration. Some runtimes do not include all services. For example, the native runtime engine and on-device PII scrubbing are capabilities of the Pro build flavor and are not present in lighter build flavors or in tiers that do not include them. Compliance-oriented capabilities are offered as engineering direction and alignment, not as a certification or warranty of regulatory compliance. We may add, change, deprecate, or remove features, and may modify or discontinue parts of the Service, with notice for material changes.

  1. YOUR DATA; OUR LIMITED LICENSE

As between you and us, you retain all rights to data, telemetry, content, and materials you submit or that your applications send through the Service ("Your Data"). You grant us a limited, non-exclusive license to host, store, process, and transmit Your Data solely to provide and support the Service. We do not claim ownership of Your Data. Our handling of personal data is described in the Privacy Policy and, where applicable, the Data Processing Addendum. You are responsible for the lawfulness of Your Data and for obtaining any required consents.

  1. ACCEPTABLE USE

Your use of the Service must comply with the Acceptable Use Policy, which is incorporated by reference.

  1. INTELLECTUAL PROPERTY

The Service and its content, features, and functionality are and remain the exclusive property of Dartastic and its licensors, protected by copyright, trademark, trade-secret, and other laws. Except for the limited rights expressly granted, no rights are granted to you. Our trademarks and trade dress may not be used without our prior written consent except as permitted by the Trademark & Brand Policy. If you submit feedback, you grant us a perpetual, irrevocable, royalty-free, worldwide license to use it for any purpose.

  1. THIRD-PARTY AND OPEN-SOURCE COMPONENTS

The Service incorporates third-party and open-source components, including OpenTelemetry (Apache 2.0) and Grafana, Loki, Tempo, and Mimir (AGPLv3), each subject to its own license. See THIRD-PARTY-NOTICES.md and OPEN-SOURCE-LICENSING.md. You are responsible for any backend or service you elect to send telemetry to that we do not operate.

  1. DISCLAIMER OF WARRANTIES

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT ANY DATA-PROTECTION FEATURE WILL CATCH EVERY CASE.

  1. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THE SERVICE WILL NOT EXCEED THE FEES YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE LIABILITY (OR USD $100 IF YOU USE ONLY FREE OFFERINGS). WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL, EVEN IF ADVISED OF THE POSSIBILITY. THESE LIMITS ARE A FUNDAMENTAL BASIS OF THE BARGAIN.

  1. INDEMNIFICATION

You will defend, indemnify, and hold harmless Dartastic and its members, officers, and agents from any third-party claim and resulting loss arising from your applications, Your Data, your use of the Service in violation of these Terms or law, or your combination of the Service with anything we did not provide.

  1. TERM, CANCELLATION, AND REFUNDS

These Terms apply while you use the Service. You may cancel at any time effective at the end of the current paid term; cancellation stops future renewals. Except where required by law or expressly stated in an Order or the SLA (service credits), fees already paid are non-refundable and there is no refund for the unused portion of a term. We may suspend or terminate your access for breach of these Terms, the Commercial License, or the Acceptable Use Policy, or for non-payment. On non-payment or cancellation, the Pro native runtime distributed to you deactivates after a grace period: it stops emitting telemetry and its licensed features become inert. This deactivation is designed to be non-disruptive — the runtime degrades to a no-op and does not crash or block your application. For Hosted Service wind-down (grace, read-only, suspended, deletion) and data-export windows, see the Hosted Services Agreement. Upon termination you must stop using the paid Service; provisions that by their nature should survive (including Sections 5, 7, 9, 10, 11, 13, and 14) survive.

  1. DISPUTE RESOLUTION; ARBITRATION; CLASS WAIVER

The parties will first attempt to resolve any dispute through good-faith negotiation and then non-binding mediation within thirty (30) days of written notice. Any dispute not so resolved shall be finally resolved by binding arbitration before a single arbitrator, seated in Sheridan County, Wyoming, in English, under the Commercial Arbitration Rules of a recognized arbitral body. EACH PARTY WAIVES ANY RIGHT TO A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION AND TO A JURY TRIAL. Either party may seek injunctive relief for intellectual-property or confidentiality matters in the courts of Sheridan County, Wyoming. The prevailing party in any proceeding to enforce these Terms may recover reasonable attorneys' fees and costs.

  1. GOVERNING LAW; CHANGES; CONTACT

These Terms are governed by the laws of the State of Wyoming, without regard to conflict- of-laws principles, and excluding the CISG. We may modify these Terms; for material changes we will provide reasonable notice (for example, by email or in-product notice), and your continued use after the effective date constitutes acceptance. By creating an account you agree to receive service-related communications; you may opt out of marketing communications at any time. Questions: legal@dartastic.io.
