Terms of Service

Effective date: June 8, 2026

These Terms of Service ("Terms") govern your access to and use of Mathesar Cloud, a hosted data-management service operated by Mathesar Foundation Inc ("Mathesar," "we," "us," or "our").

By creating an account, signing in, or using Mathesar Cloud, you agree to these Terms and our Privacy Policy. If you use Mathesar Cloud on behalf of an organization, you represent that you have authority to bind that organization, and "you" includes that organization.

If you do not agree to these Terms, do not use Mathesar Cloud.

Mathesar Cloud And Open-Source Mathesar

Mathesar Cloud is the hosted service operated by Mathesar Foundation. The open-source Mathesar project and self-hosted deployments of Mathesar are separate from Mathesar Cloud. Self-hosted deployments are governed by the applicable open-source license and project documentation, not these Terms, except when you interact with Mathesar Foundation hosted services such as our websites, forms, support channels, mailing lists, or Cloud service.

Accounts

You must provide accurate account information and keep it current. You are responsible for maintaining the security of your account and for activity that occurs through your account.

You may not share account credentials, access another person's account without permission, or use Mathesar Cloud in a way that bypasses account, access, or security controls.

You must be at least 13 years old to use Mathesar Cloud. If you are under the age of majority where you live, you may use Mathesar Cloud only with consent of a parent or legal guardian.

Beta And Free Service

Mathesar Cloud may include beta, free, preview, experimental, or early access features. These features may change, have limits, be unavailable, or be removed at any time.

We may set or change limits on storage, databases, forms, files, users, requests, exports, imports, or other service usage. We will try to communicate material changes when practical, but Mathesar Cloud may evolve quickly during beta and early access periods.

Do not rely on beta, preview, or free features for use cases that require guaranteed availability, formal compliance commitments, data residency, service levels, or dedicated support unless we agree otherwise in writing.

Customer Content

"Customer Content" means information you submit, upload, import, create, connect, manage, or share through Mathesar Cloud. Customer Content may include data stored in or connected to your database, form submissions, files, metadata, exports, and related content.

You retain the rights you have in your Customer Content. These Terms do not give Mathesar ownership of your Customer Content.

You grant Mathesar the limited rights needed to provide, secure, maintain, troubleshoot, support, and operate Mathesar Cloud; respond to your requests; prevent abuse; comply with law; and follow your directions through the service or our agreements with you.

You are responsible for your Customer Content and for ensuring that you have the rights, permissions, and legal basis needed to use it with Mathesar Cloud. This includes responsibility for data submitted through forms, public links, shared surfaces, imports, files, and databases you create or control.

We do not use Customer Content for advertising, retargeting, cross-site behavioral advertising, or AI model training.

Mathesar Cloud may allow you to create forms, links, files, databases, exports, or other shared surfaces. Some shared surfaces may be public by link. You are responsible for what you publish, share, collect, or make available through those surfaces.

If roles, permissions, collaborator, administrator, owner, or similar controls are available, you are responsible for configuring them appropriately. Do not use public links, forms, or shared surfaces to collect, expose, or share information you are not authorized to use.

Acceptable Use

You may not use Mathesar Cloud to:

  • violate any law or regulation;
  • infringe or misappropriate intellectual property, privacy, publicity, or other rights;
  • upload, process, publish, or share unlawful, harmful, abusive, harassing, defamatory, fraudulent, deceptive, or otherwise objectionable content;
  • send spam, unsolicited messages, or unlawful marketing communications;
  • distribute malware, spyware, ransomware, harmful code, or other malicious materials;
  • phish, harvest credentials, impersonate others, or misrepresent your identity or affiliation;
  • probe, scan, test, attack, bypass, or interfere with Mathesar Cloud or another system without authorization;
  • access or attempt to access accounts, data, systems, or networks you are not authorized to access;
  • overload, disrupt, degrade, or abuse Mathesar Cloud or our service providers;
  • circumvent usage limits, access controls, security controls, billing controls, or service restrictions; or
  • help anyone else do any of the above.

Restricted Data

Unless Mathesar agrees otherwise in writing, you may not use Mathesar Cloud to store, process, collect, publish, or share information that requires special legal, contractual, or regulatory handling, including:

  • protected health information or information subject to HIPAA-like health data obligations;
  • payment card data or cardholder data subject to PCI DSS;
  • government identifiers such as Social Security numbers, passport numbers, driver's license numbers, national ID numbers, or similar identifiers;
  • children's personal information;
  • regulated financial, insurance, education, or health records;
  • biometric, genetic, precise geolocation, or similarly sensitive data;
  • account passwords, API keys, private keys, access tokens, seed phrases, or production secrets;
  • export-controlled, sanctions-restricted, classified, or unlawful data;
  • emergency, life-safety, high-risk, mission-critical, or regulated use cases; or
  • data you are contractually prohibited from using with Mathesar Cloud.

This does not mean Mathesar Cloud is unsuitable for ordinary business records. It means specially regulated or high-risk data requires a separate written agreement and operational review before use.

Security Research

Do not test or probe Mathesar Cloud, user accounts, public links, forms, databases, infrastructure, or service providers without written authorization from Mathesar.

If you believe you found a vulnerability, report it to support@mathesar.cloud and do not exploit it, access Customer Content, disrupt the service, or disclose it publicly until Mathesar has had a reasonable opportunity to investigate.

Privacy And Support Access

Our Privacy Policy explains how we collect, use, disclose, and protect information when you use Mathesar Cloud and Mathesar Foundation hosted services.

Mathesar may provide support through email, forms, documentation, or other channels. We do not guarantee a particular support response time unless we agree otherwise in writing.

Authorized Mathesar personnel may access account information, technical data, and Customer Content when reasonably necessary to provide, secure, troubleshoot, maintain, or support Mathesar Cloud; respond to your requests; investigate abuse or security issues; or comply with legal obligations. We limit such access to authorized personnel with a need to know.

Third-Party Services

Mathesar Cloud may use or interact with third-party services, including hosting, infrastructure, authentication, email, form, survey, analytics, support, and communications providers. Third-party services may have their own terms and privacy policies.

If you choose to sign in through Google, GitHub, or another supported provider, that provider may process information under its own terms and privacy policy.

Service Changes, Suspension, And Termination

We may modify, suspend, or discontinue Mathesar Cloud, or any part of it, at any time. We will try to provide reasonable notice of material changes when practical.

We may suspend or terminate your access to Mathesar Cloud if we reasonably believe that:

  • you violated these Terms;
  • your use creates security, legal, operational, or reputational risk;
  • your account is inactive;
  • your use exceeds applicable limits;
  • we are required to do so by law or by a service provider; or
  • continuing to provide the service is no longer practical.

You may stop using Mathesar Cloud at any time. You may contact support@mathesar.cloud to request account deletion.

Export, Deletion, And Data Availability

Mathesar Cloud may provide product features that allow you to export or delete some Customer Content directly. You may also contact support@mathesar.cloud to request access to, export of, or deletion of your account information or Customer Content.

Deleted information may remain in backups, logs, or archival copies for a limited period according to our normal backup, security, and retention practices, unless we need to retain it longer for legal, security, abuse-prevention, or operational reasons.

You are responsible for exporting or backing up Customer Content you need before deleting it, closing your account, or relying on a beta or free service that may change.

Fees

Mathesar Cloud may currently be offered as a free or beta service. We will not charge you unless you choose a paid offering and provide any required billing information. If paid offerings are made available, pricing, payment, renewal, cancellation, taxes, and refund terms may be provided in the applicable plan, order, checkout flow, or additional terms.

Feedback

If you provide feedback, suggestions, or ideas about Mathesar Cloud, you grant Mathesar permission to use them without restriction or compensation. This does not give Mathesar ownership of your Customer Content.

Disclaimers

Mathesar Cloud is provided "as is" and "as available." To the maximum extent permitted by law, Mathesar disclaims all warranties, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, availability, reliability, security, and error-free operation.

Mathesar Cloud is not designed for emergency, life-safety, high-risk, mission-critical, or regulated uses unless we agree otherwise in writing.

Limitation Of Liability

To the maximum extent permitted by law, Mathesar Foundation Inc and its officers, directors, volunteers, maintainers, contributors, contractors, and agents will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenues, goodwill, data, or business opportunities.

To the maximum extent permitted by law, Mathesar's total liability arising out of or relating to Mathesar Cloud or these Terms will not exceed the greater of the amount you paid Mathesar for Mathesar Cloud during the 12 months before the claim or $100.

Some jurisdictions do not allow certain limitations of liability, so some of these limitations may not apply to you.

Indemnity

You will defend, indemnify, and hold harmless Mathesar Foundation Inc and its officers, directors, volunteers, maintainers, contributors, contractors, and agents from claims, damages, liabilities, costs, and expenses, including reasonable attorneys' fees, arising from your Customer Content, your use of Mathesar Cloud, your violation of these Terms, or your violation of law or third-party rights.

Governing Law And Venue

These Terms are governed by the laws of the Commonwealth of Massachusetts, without regard to conflict of law rules. The state and federal courts located in Massachusetts will have exclusive jurisdiction over disputes arising from these Terms or Mathesar Cloud, except that either party may seek injunctive or equitable relief in any court of competent jurisdiction.

Changes To These Terms

We may update these Terms from time to time. If we make material changes, we will provide notice as appropriate, such as by posting the updated Terms on this page, sending email, or providing notice through Mathesar Cloud.

Your continued use of Mathesar Cloud after updated Terms take effect means you accept the updated Terms.
