What is Stellar

What Stellar does

The core mWater platform stays free, including data collection, analysis, visualization, and sharing. Even the AI integrator for bringing in external data has a free tier open to every organization — only higher-volume use is paid. Stellar offers optional premium services for organizations that need higher data limits or dedicated support. You don't need a separate Stellar account, and everything is activated inside your existing mWater organization.

Products & Pricing

Optional premium services, billed by Stellar

Premium services are optional additions for organizations that need dedicated expert support or higher data limits. The two tiers are independent — subscribe to either one, or both. You purchase here, and the relevant features are activated inside your organization's mWater workspace. You will receive a confirmation email when your subscription is live.

Main offering

Partnership Support Tier

Get fast, expert help from the mWater team to solve complex issues, design better workflows and dashboards, and keep your monitoring systems running without disruption. This tier is about expert help and enhanced platform capabilities, not data volume.

Who it is for. Active mWater implementers that depend on the platform for day-to-day operations: NGOs, utilities, government programs, and consultancies. Utilities and other large organizations subscribe here for support whether or not they also need the API tier.

Expert support included
  • Priority handling of complex support requests
  • Restoring deleted sites, tables, or deployments
  • Shapefile and geospatial asset imports
  • Integrations with external platforms such as ODK, Kobo, and DHIS2
  • Workflow and process design

Platform capabilities included
  • 100× table data import limits — up to 1,000,000 rows per table import (a per-import ceiling, not total data storage)
  • Bulk operations on up to 1,000 sites or records at once
  • Higher allowances for AI-powered features
  • Priority beta access to new features
$250/ month
or $2,500 a year, about $208 a month, with two months free.

Ensure data integrity and uninterrupted operations for the monitoring programs your organization depends on.

Also available

API Data Tier

Who it is for. Organizations that need programmatic access to large mWater datasets, for example to power external dashboards, connect to other systems, or run automated pipelines. This includes utilities bringing sensor-network data into mWater.

What is included
  • Full access to all mWater data API endpoints, read and write, for your organization's data
  • Continuous, high-frequency feeds — sensors, SCADA, billing systems — are brought in through the AI integrator, which batches writes, so they are not bound by per-endpoint API limits
  • Direct API endpoints are rate-limited to one request per hour per endpoint; use the integrator for sub-hourly or bulk ingestion
Storage
  • Free for everyone: full read and write API access for up to 10,000 stored rows, at no cost
  • Standard (paid) tier: up to 10,000,000 stored rows total in your organization, across all tables
  • Usage is measured in rows stored in your mWater organization
  • If you cancel, rows above 10,000 become read-only — your data is never deleted, you simply stop adding to it until you resubscribe
$500/ month
or $5,000 a year, two months free, for up to 10,000,000 stored rows.

The Standard tier covers survey-based NGO and government monitoring programs, and small utilities with sensor networks such as 100 sensors reporting sub-hourly. For larger deployments, contact us to discuss your needs.

About Stellar

Why Stellar exists

The mWater core platform will remain free and unlimited for all users, consistent with our founding commitment. New AI-enabled features that import and store external data from sensors and third-party systems require significant additional server resources and ongoing infrastructure costs.

Stellar, Inc. is a wholly owned for-profit subsidiary created to offer these premium data integration and AI-powered analytics services on a paid basis. Its profits flow back to the nonprofit to sustain and expand the free platform.

No existing features move behind a paywall. The entire mWater platform, including collection, analysis, visualization, and sharing, stays free.

What Stellar provides

Stellar provides AI-powered connectors that import external datasets such as sensor feeds, SCADA, and billing systems into mWater's database, so they can be analyzed alongside your existing asset and operations data. The connectors and analytics both include a free tier open to every organization, with paid plans only for higher-volume use.

Governance and mission

Stellar is wholly owned by mWater Foundation, Inc., a 501(c)(3) nonprofit. The nonprofit board retains governance authority. All core platform intellectual property remains with the nonprofit, and all Stellar profits belong to the Foundation and support its mission to democratize access to data and technology. Verified government and public-sector users in countries on the UN Least Developed Countries (LDC) list receive subsidized or free access.

Terms of Service

Stellar, Inc. Premium Services · Effective June 15, 2026 · Last updated June 2026

These Terms of Service ("Terms") govern your access to and use of the premium paid services ("Services") offered by Stellar, Inc. ("Stellar"), a wholly owned subsidiary of mWater Foundation, Inc., a 501(c)(3) nonprofit organization. By purchasing or using the Services, you agree to these Terms.

1. About Stellar, Inc.

Stellar, Inc. is a for-profit subsidiary of mWater Foundation, Inc., the nonprofit that operates the mWater platform. Stellar offers premium data integration and AI-powered analytics services on a commercial basis. Profits support the continued development and free availability of the mWater platform. The core mWater platform — including data collection, analysis, visualization, sharing, and all current functionality — remains free and is governed separately. These Terms apply only to Stellar's paid premium Services.

2. The Services

2.1 API Data Tier. Access to the full mWater data API (all endpoints, read and write). Usage is measured in rows stored in the subscriber's mWater organization. Full read and write API access for the first 10,000 stored rows is free for every organization; organizations requiring larger storage may subscribe to a paid API tier for up to 10,000,000 stored rows total. Direct API endpoints are rate-limited to one request per hour per endpoint; continuous or high-frequency data (e.g. sensor and SCADA feeds) is ingested through the AI integrator, which batches writes and is not bound by that per-endpoint limit. If a subscription ends, stored rows above the free 10,000 threshold are retained on a read-only basis and are not deleted by Stellar. Pricing: $500/month, or $5,000/year (two months free), for up to 10,000,000 stored rows.

2.2 Partnership Support Tier. A premium support and capability package including: priority responses to complex support requests (restoring deleted data, shapefile and asset imports, platform integrations, workflow design, calculations and indicator support, advanced query and dashboard design); access to a direct support Slack channel with the mWater/Stellar team; 100× table data import limits (up to 1,000,000 rows per table); bulk data operations (e.g. updating up to 1,000 sites at once); and priority beta access to new features. Pricing: $250/month, or $2,500/year (two months free).

2.3 Additional Services. Additional services, including AI-powered data connectors and analytics, may be made available. Pricing and terms will be published at the time of launch.

3. Eligibility and Account Access

3.1 Organizational Accounts. The Services are sold to organizations, not individuals. The person completing the purchase must have authority to bind the organization to these Terms.

3.2 Access Method. Services are accessed through your organization's existing mWater account at portal.mwater.co. There is no separate application to download or account to create. Initial activation is handled manually by Stellar staff following confirmation of payment; you will receive a confirmation email when your subscription is active.

3.3 Subsidized Access. Verified government and public-sector organizations in countries on the United Nations Least Developed Countries (LDC) list may be eligible for subsidized or free access. To apply, contact support@stellardata.co.

4. Payment and Billing

4.1 Payment Processor. Payments are processed by Paddle.com Market Limited ("Paddle"), which acts as Merchant of Record for all transactions. By completing a purchase, you also agree to Paddle's terms of service. Paddle handles all payment processing, tax collection, and compliance on Stellar's behalf.

4.2 Subscriptions. Services are sold as monthly or annual subscriptions. Subscriptions renew automatically at the end of each billing period unless cancelled before the renewal date.

4.3 Pricing. Prices are listed in USD. Taxes may be added at checkout depending on your jurisdiction and are collected and remitted by Paddle.

4.4 Cancellation. You may cancel at any time through your account settings or by contacting us. Cancellation takes effect at the end of the current billing period. You retain access to paid features until that date. After a paid subscription ends, any stored data above the free 10,000-row threshold remains accessible on a read-only basis and is not deleted by Stellar; elevated limits simply stop applying to new data until you resubscribe.

5. Refunds

Refunds are governed by our Refund Policy at stellardata.co/refunds. New subscribers may request a full refund within 14 days of initial payment. Subscriptions are otherwise non-refundable except in cases of billing error or where required by applicable law. Paddle, as Merchant of Record, processes all refund requests.

6. Acceptable Use

You agree to use the Services only for lawful purposes and in accordance with these Terms. You may not: resell or sublicense access without written permission from Stellar; use the Services to store or process data in violation of applicable law; attempt to circumvent usage limits or access controls; or interfere with or disrupt the Services or underlying servers.

7. Data and Privacy

8. Intellectual Property

9. Disclaimer of Warranties

The Services are provided "as is" and "as available." Stellar makes no warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, or uninterrupted availability.

10. Limitation of Liability

To the maximum extent permitted by law, Stellar's total liability for any claim arising from the Services shall not exceed the fees you paid to Stellar in the three months preceding the claim. In no event shall Stellar be liable for indirect, incidental, consequential, or punitive damages.

11. Governing Law and Disputes

These Terms are governed by the laws of the State of New York, United States, without regard to its conflict-of-law provisions. Any dispute arising out of or relating to these Terms or the Services that cannot be resolved through good-faith negotiation shall be subject to the exclusive jurisdiction of the state and federal courts located in New York County, New York. You consent to personal jurisdiction and venue in those courts and waive any objection thereto.
