Chalk

Terms of Service

Last updated 2026-05-14

1. Acceptance

By creating a tenant or using the hosted Chalk service ("Service"), you agree to these Terms on behalf of the school or district you represent ("District"). If you lack authority to bind the District, do not use the Service.

2. The Service

Chalk is an SIS sync and identity platform connecting systems such as PowerSchool, Skyward, and Infinite Campus to downstream applications via OneRoster, SAML 2.0, OIDC, Google Workspace, and Active Directory. Features may change over time.

3. Eligibility — free for K-12 schools

The Service is free for accredited K-12 public, private, charter, and parochial schools and districts. Chalk reserves the right to verify eligibility and to discontinue free access for entities that do not qualify (for example, ed-tech vendors using the platform for resale without a commercial agreement).

4. Account security

You are responsible for safeguarding administrator credentials, API tokens, and SSO secrets issued under your tenant, and for all activity under your account. Notify us promptly of any suspected compromise.

5. Acceptable use

You agree not to:

  • process data you lack a lawful basis to process;
  • attempt unauthorized access to other tenants or to Chalk infrastructure;
  • reverse-engineer the hosting environment (source code is openly available under AGPL-3.0);
  • use the Service to send unsolicited bulk email, malware, or unlawful content;
  • resell, sublicense, or repackage the hosted Service without a written agreement.

6. District responsibilities

The District is responsible for the accuracy of data it submits, for managing accounts and access within its tenant, for maintaining a lawful basis (including FERPA school-authorization or equivalent) for the data sources it connects, and for any required parental or staff notices.

7. Chalk responsibilities

Chalk will use commercially reasonable efforts to keep the Service available and secure. Security commitments are described in our Privacy Policy, DPA, and Security page. The free tier is provided without a contractual SLA; targets and historical uptime are published on our status page but are not binding unless agreed in writing.

8. Intellectual property & feedback

Chalk and its licensors retain all rights in the Service not expressly granted. The District retains all rights in its data. If you provide feedback or suggestions about the Service, you grant Chalk a perpetual, royalty-free license to use that feedback to improve the Service.

9. Open-source license

The Chalk source code is published under the GNU Affero General Public License v3.0 (AGPL-3.0) at https://github.com/usechalk/chalk. Self-hosting is governed by the AGPL-3.0. Use of the hosted Service is governed by these Terms in addition to (not in lieu of) the AGPL-3.0 where both apply.

10. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, CHALK DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. CHALK DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CHALK WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, OR DATA. FOR THE FREE TIER, CHALK'S AGGREGATE LIABILITY WILL NOT EXCEED [placeholder — confirm with counsel].

12. Indemnification

The District will defend and indemnify Chalk against third-party claims arising from (a) data the District submits in breach of these Terms or applicable law, or (b) the District's use of the Service in violation of Section 5 (Acceptable use). Chalk will promptly notify the District of any such claim and reasonably cooperate in the defense.

13. Termination

Either party may terminate use of the Service at any time. Chalk may suspend or terminate a tenant for material breach, for activity that endangers other tenants or the platform, or where required by law. On termination, the District may export its data; Chalk will delete tenant data within 30 days, subject to the retention windows in the Privacy Policy.

14. Force majeure

Neither party will be liable for delay or failure to perform due to causes beyond reasonable control, including acts of God, war, civil unrest, labor disputes, internet or utility outages, or governmental action.

15. Governing law

These Terms are governed by the laws of [placeholder — confirm with counsel], without regard to conflict-of-laws principles. The parties consent to the exclusive jurisdiction of the courts located there.

16. Changes

We may update these Terms from time to time. Material changes will be announced to District administrators at least 30 days before they take effect. Continued use after the effective date constitutes acceptance.
