Privacy policy
This policy explains the information ChalkLab processes when educators create lessons and learners use activities shared by an educator. Use ChalkLab thoughtfully with learner information, especially information about children.
Last updated: October 6, 2026
Information we process
Account and profile information. We process information used to create and secure an account, such as an email address, account identifier, and profile details provided through sign-in.
Educator content. Lessons, prompts, conversations, classes, and student profiles may include names, language levels, goals, interests, learning needs, mistakes, and teacher notes that an educator chooses to enter.
Activity responses. When a learner opens a shared activity, ChalkLab may process answers, scores, feedback, timestamps, session details, audio responses, and a name typed into the activity. A typed name does not verify a learner’s identity.
Files and media. ChalkLab may process images and other files an educator uploads or uses in a lesson. Some media links may be publicly accessible to anyone who has the link, and copies may remain in browser or delivery-network caches for up to one year.
Usage, diagnostics, and billing. We and our service providers may process device and page activity, interaction events, session diagnostics or replay data, account identifiers, and subscription records needed to operate, support, secure, and improve the service.
How we use information
We use information to provide sign-in and account features; create, personalize, save, and share lessons; let learners complete activities; generate content when requested; provide exports and integrations; process subscriptions; answer support requests; and maintain service security, reliability, analytics, and debugging.
AI features and other providers
When an educator requests AI-generated content, the prompt and relevant lesson or student context may be sent to the model provider used for that feature. Depending on the feature, providers may include OpenAI, Anthropic, Google Gemini, or ElevenLabs. Avoid including sensitive personal information in prompts.
ChalkLab also relies on service providers for hosting, authentication and storage (including Firebase and Google services), payments (Stripe), analytics and diagnostics (including Amplitude, Mixpanel, LogRocket, and Sentry), and educator-requested integrations or exports such as Canva and Google services. These providers process information to support the features in use, under their own terms and privacy practices.
Educators and learner information
Educators and schools are responsible for deciding what learner information to enter or share, having the authority and permissions required to do so, and providing learners and families any notices required for their setting. Use the minimum information needed for an activity and avoid sensitive information. Learners may be able to use a teacher-shared activity without creating a ChalkLab account.
Cookies, analytics, and diagnostics
ChalkLab uses cookies or similar browser storage for sign-in and session features. Analytics and diagnostic tools may collect page views, interactions, device or session information, and account identifiers; some tools may record session replay or interaction details. These tools help us understand and troubleshoot the service.
Storage, retention, and requests
Information is stored with service providers that operate ChalkLab. We do not currently publish one fixed retention period for all information or provide a self-service way to delete an entire account. Some content can be removed through product controls, but related activity records, provider copies, backups, or diagnostics may not be removed at the same time. For a privacy question or request, contact support@chalklab.app. We will review requests in light of applicable requirements and the systems involved.
Security and changes
We use service providers and operational measures to protect the service, but no online service can guarantee absolute security. We may update this policy as ChalkLab changes. The updated date at the top indicates the latest revision shown on this page.
