Chaklin

Privacy Notice

Last updated: August 17, 2026

1. Who we are

Chaklin is operated by Patounezambo Ouedraogo d/b/a Chaklin, which is the data controller for personal data processed through chaklin.com. For student work you submit for grading, you (or your school) are the controller and we act as your processor, handling that data only on your instructions. Contact us any time at support@chaklin.com.

2. What we collect and why

  • Account data — name, email address and login credentials (or the name and email Google shares when you sign in with Google; we never see your Google password). Used to create and secure your account. Legal basis: performance of our contract.
  • Teaching content — the topics, standards, prompts and files you submit, and the lesson plans, worksheets, quizzes, slides, visuals, storyboards and parent letters we generate. Used to provide the service and let you revisit your library. Legal basis: contract.
  • Student work — answers, uploaded photos or documents, and the scores and feedback produced. Used only to return a grade to you and, if you choose, to your Google Classroom gradebook. Legal basis: our contract with you / your school as controller.
  • Google Classroom data — OAuth tokens, your course list, coursework and submission identifiers, only when you connect the integration. Legal basis: your consent.
  • Usage and billing metadata — counts of materials and gradings, plan tier, storage used, model and token counts, plus subscription status from our payment provider. Used to enforce plan limits, bill accurately and control AI cost. Legal basis: contract and legitimate interests.
  • Technical data — IP address, device and browser information, and error logs. Used for security, fraud prevention and debugging. Legal basis: legitimate interests.
  • Support messages — what you send us by email. Used to answer you. Legal basis: legitimate interests.

We do not sell personal data, we do not run advertising, and we do not use your content or student submissions to train AI models.

3. AI processing

Generation and grading requests are sent to AI model providers through our AI gateway so the model can return content or a score. Requests are processed to serve you and are not used by us or, under our provider terms, by the model providers to train models. Outputs may be inaccurate — you review everything before it reaches a student or parent.

4. Student data and children's privacy

Chaklin is sold to teachers and schools, not to children. Students do not create Chaklin accounts: they open an assignment link, answer, and submit. We ask for no more than a student name or identifier supplied by you, we never ask students for contact details, and we do not profile students or target them with marketing. Where a school directs us as a school official under FERPA, we use student data only for the educational purpose you set and delete it on request. We do not knowingly collect personal information from children under 13 outside such a school relationship. If you believe a student's data was sent to us in error, email support@chaklin.com and we will delete it.

5. Google Classroom

Connecting Google Classroom is optional. When you connect it we store encrypted access and refresh tokens so we can list your courses, post assignments, and write scores back to your gradebook. We request the narrowest scopes needed, never read student data beyond the coursework you posted through Chaklin, and never share Google user data with third parties. Disconnect at any time on the Integrations page — the tokens are deleted and access stops immediately.

6. Who we share data with

  • Infrastructure and subprocessors — hosting, database, storage, email delivery and AI model providers, under contract and only to run the service.
  • Paddle.com — our reseller and Merchant of Record, for the sale of subscriptions, subscription management, payments, tax compliance and invoicing. Paddle collects and processes your payment details directly under its own privacy policy; we never see your full card number.
  • Google — only when you connect Google Classroom or sign in with Google.
  • Professional advisers — legal and accounting, where necessary.
  • Authorities — where we are legally required to disclose.

7. International transfers

Our providers may process data outside your country, including in the United States. Where data leaves the UK or EEA we rely on adequacy decisions or Standard Contractual Clauses with appropriate safeguards.

8. Retention

Account data is kept while your account is active. Generated materials are kept until you delete them or close your account. Student work and grading artefacts follow your plan's retention schedule and are then deleted automatically. Billing and usage records are kept as long as tax and accounting law requires. When data is no longer needed we delete or anonymise it. Request full account and content deletion at any time by emailing support@chaklin.com.

9. Your rights

Depending on where you live you may ask us to give you access to your data, correct it, delete it, restrict or object to processing, port it elsewhere, or withdraw a consent you gave (for example the Google Classroom connection). Most of this you can do yourself in the app; for anything else email support@chaklin.com and we will respond within one month. If you are in the UK or EEA you can also complain to your supervisory authority.

10. Security

We apply appropriate technical and organisational measures: encrypted connections, encryption at rest, row-level database access control so teachers only reach their own records, restricted internal access, and audited administrative actions. No system is perfectly secure, so we also keep the personal data we hold to the minimum the service needs.

11. Cookies

We use strictly necessary cookies and local storage to keep you signed in, remember your language, and secure checkout. We do not use advertising cookies. You can clear or block cookies in your browser, though sign-in will stop working.

12. Changes and contact

We may update this notice as the service evolves and will tell you about material changes by email or in the app. Questions, requests or complaints: support@chaklin.com. See also our Terms of Service and Refund Policy.
