Terms of Use

The current public-entry terms for CL Learning Labs.

Version terms-2026-08-13 · Effective August 13, 2026

These terms describe the current public release candidate. They are limited to the product surfaces and teacher entry described below. Questions can be sent to support@cllearninglabs.com.

Public pages and the guided demo

The public site provides informational pages. The guided demo is a synthetic, read-only preview. It is not a live classroom and should not contain real student names, student work, or personal information.

Current limited teacher entry

When the applicable release flags are enabled, the current new-teacher entry is limited-A2 access for an adult educator or authorized instructor. A new teacher may use Google or secure email/password signup. It is a one-time 30-day teacher preparation trial. No card is required, there is no automatic charge, and the teacher must explicitly start the trial after completing the required profile and agreement steps.

Limited-A2 access is for private teacher preparation. It permits private teacher-owned draft classes, multiple-choice practice drafts, and writing drafts. It does not permit student enrollment, joins, class activation, classroom use, lifecycle email, payment, or automatic charging. Do not enter real student names, student work, or personal information into this private preparation workspace.

Active work is available before the exact trial end date shown in the workspace. Beginning on day 31, active-work actions pause. The account, profile and support access, and saved private drafts remain available as provided by this feature. Trial expiry itself does not delete the account or drafts.

Future continuation

A future optional continuation may be considered at $12/month. It is unavailable today while commerce is off. No payment details are requested and no charge occurs from the current limited-A2 release. These terms do not promise a first charge date.

Returning accounts

Returning legacy accounts may have previously granted a different scope of access. This release does not relabel legacy users as accepting the current policy versions and does not silently change their existing scope.

AI and teacher judgment

AI features are advisory and may be incomplete or wrong. A separately enabled feature receives only the context needed for that feature when it is invoked. AI does not replace teacher judgment or the teacher's responsibility for consequential instructional decisions. Limited-A2 private preparation does not include AI features today unless a feature is separately made available and explicitly invoked.

Acceptable use

Use the available product surfaces only for their stated purpose. Do not:

  • share account credentials or use another person's account;
  • attempt to access another user's records or a class you do not own or join;
  • scrape, disrupt, or probe the service or its access controls;
  • submit harmful, unlawful, or unrelated sensitive information; or
  • use the guided demo as a place for real student data.

Archive and retained records

An archive is a retention state, not deletion. Records may remain subject to the applicable product retention schedule, school controls, authorized requests, dependencies, and backup aging. The Privacy Notice explains the current data categories and retention limits.
