Account and Data Deletion Policy

Last Updated: September 5, 2026Sommerfeld Educational Platform respects the rights of users to control their accounts and personal information.This Policy explains how users may request deletion of a Sommerfeld account or personal information associated with an account, what happens after a deletion request is submitted, and the circumstances in which certain information may need to be retained.This Policy forms part of the Sommerfeld Privacy and Data Protection Policy and should be read together with it.1. Account Deletion vs. Data DeletionUsers may make two different types of deletion requests.Account DeletionAn account deletion request closes the Sommerfeld account and results in deletion of associated personal information that Sommerfeld no longer has a lawful or legitimate reason to retain.After deletion is completed, the user will no longer be able to sign in to the account or access the services and information associated with it.Deletion of Specific Personal InformationWhere permitted by applicable law, a user may request deletion of certain personal information without necessarily closing the entire account.Deleting information required to provide a particular service may affect our ability to continue providing that service.2. Who Can Request Account Deletion?The account holder may request deletion of the account.For accounts used by minor students, the account is created and managed by a parent or legal guardian. Requests to delete the student's account or information should therefore be submitted by the parent, legal guardian, or other authorized account holder.We may request additional information to verify the identity and authority of the person submitting the request before completing a deletion.3. Minor Student AccountsMinor students are not required to maintain independent Sommerfeld accounts.The parent or legal guardian creates and manages the account and controls the student's educational services, bookings, payments, and information provided to Sommerfeld.When the parent or guardian requests deletion of the account, the request will generally include personal information concerning the student that is associated with that account, except for information that Sommerfeld is legally permitted or required to retain.Parents and guardians may also contact Sommerfeld to request review, correction, or deletion of particular information associated with a minor student.4. How to Request Account DeletionA Sommerfeld account deletion request may be submitted through the deletion methods made available by Sommerfeld, which may include:The Delete Account option within the application settings.The Account Deletion page on the Sommerfeld website.The Contact Us form.Official Sommerfeld support channels.We may require the user to sign in or complete an additional verification step before the deletion process begins.5. Verifying the RequestWe verify deletion requests in order to protect accounts against unauthorized deletion.Depending on the circumstances, verification may include:Signing in to the account.Confirming an email address or telephone number.Confirming information associated with the account.Providing additional information where reasonably necessary.Sommerfeld Support will not ask users to provide their account password to a support representative.6. What Happens When an Account Is Deleted?After a deletion request has been verified, Sommerfeld may:Close or disable access to the account.Terminate active login sessions.Remove the user profile.Delete or de-identify personal information that we no longer need to retain.Delete information associated with a minor student where applicable.De-identify records that may lawfully be retained in anonymous form.Instruct relevant service providers to process information associated with the deleted account in accordance with applicable contractual and legal requirements.Account deletion is not the same as temporarily suspending or freezing an account.Once the deletion process is completed, the account is considered deleted and will no longer be available for normal use.7. Information We Normally DeleteDepending on the type of account and how Sommerfeld has been used, information deleted or de-identified may include:Profile information.Contact information that is no longer required to be retained.Account settings.User preferences.Student information provided by the parent or guardian.Certain usage records directly associated with the account.Data or content that is no longer necessary to provide the service or satisfy legal requirements.The specific information deleted may vary depending on the type of account and services used.8. Information We May RetainCertain information may need to be retained after an account is deleted where retention is legally required or otherwise permitted for legitimate purposes.Reasons for retaining information may include:Tax and accounting obligations.Payment and invoice records.Refunds and payment disputes.Compliance with legal or regulatory obligations.Establishing, exercising, or defending legal claims.Resolving an existing dispute.Detecting or preventing fraud or abuse.Protecting our systems and users.Maintaining records necessary to demonstrate completed transactions.Enforcing Sommerfeld's Terms and Conditions.Where information is retained for one of these purposes, we will not use it to continue providing normal services through the deleted account.9. Financial and Payment RecordsCertain transaction records may remain after account deletion when reasonably necessary for:Accounting.Tax purposes.Auditing.Fraud prevention.Handling payment disputes.Documenting payments or refunds.These records may include transaction references, amounts, transaction dates, and other information necessary to maintain appropriate financial records.Retention of a financial transaction record does not mean that the user's Sommerfeld account remains active.10. BackupsCertain information may temporarily remain within system backups after it has been deleted from Sommerfeld's active systems.Information stored solely in backups will not normally be used to recreate or reactivate a deleted account.It will be deleted or overwritten according to our normal backup and retention cycles unless continued retention is legally required.11. Anonymous and Aggregated InformationSommerfeld may retain statistical, aggregated, or de-identified information that cannot reasonably be used to identify a particular individual.For example, we may retain general statistics concerning:The number of bookings.Usage of Platform features.Technical performance.General service usage trends.Such information is not treated as an active personal account where it can no longer reasonably be connected to the identity of the user.12. Active Lessons and BookingsDeleting an account may affect active or future lessons and bookings.Before completing deletion, Sommerfeld may need to:Cancel future bookings.Address prepaid lessons that have not yet been used.Resolve outstanding amounts.Terminate ongoing services associated with the account.Eligibility for a refund is determined under the Sommerfeld Cancellation and Refund Policy.Account deletion itself does not automatically create a right to a refund.13. Packages and CreditsIf an account contains unused packages, credits, or services when a deletion request is submitted, those items will be handled according to the Sommerfeld Cancellation and Refund Policy and the terms applicable to the relevant package or promotion.Completion of account deletion may result in the loss of access to remaining credits or services.Users should therefore review active bookings, packages, and balances before confirming permanent deletion.14. Recurring SubscriptionsIf a user has an active recurring paid subscription, the subscription may need to be cancelled before or during the account deletion process.Subscriptions purchased through a third-party application marketplace may need to be cancelled separately through that marketplace.Deleting the Sommerfeld application from a device does not necessarily cancel a subscription or delete a Sommerfeld account.15. Third-Party PaymentsWhere a payment has been processed by a bank, card issuer, payment processor, or other third party, that organization may maintain its own transaction records in accordance with its legal obligations and privacy policies.Sommerfeld cannot delete information independently maintained by a third party outside Sommerfeld's systems where Sommerfeld does not control that information.16. Teachers and ContractorsTeachers and contractors may request deletion of their Sommerfeld accounts and associated information, subject to information we may need to retain concerning:Contracts.Amounts payable.Invoices.Tax records.Previous payments.Disputes.Legal and regulatory requirements.Evidence of services previously provided.Closing an account does not cancel outstanding legal or financial obligations between Sommerfeld and a teacher or contractor.17. Job ApplicantsApplicants for employment or contractual opportunities with Sommerfeld may request deletion of personal information submitted during the recruitment process where applicable law permits.Certain records may be retained where Sommerfeld has a lawful or legitimate reason to do so, including handling a claim or satisfying a legal obligation.18. How Long Does Deletion Take?We seek to process account and data deletion requests without undue delay.Deletion requests will generally be processed within 30 days after the request has been verified, unless the nature of the request or applicable law requires a different period.Removal from backups and certain technical systems may take additional time in accordance with the normal retention cycles of those systems.Where applicable law requires a shorter response period or different procedure, the applicable legal requirement will control.19. When We May Deny or Limit DeletionSommerfeld may be unable to delete all requested information where continued retention is legally required or otherwise permitted.Examples may include information necessary to:Complete an existing transaction or obligation.Handle a claim or dispute.Detect a security incident or prevent fraud.Comply with applicable law.Exercise or defend legal rights.Maintain legally required tax or financial records.Perform another internal use permitted under applicable law.Where appropriate or legally required, we may explain why particular information cannot be deleted.20. Cancelling a Deletion RequestBefore deletion is completed, Sommerfeld may permit a user to cancel a deletion request if final deletion has not yet begun.Once permanent deletion has been completed, it may not be possible to:Restore the account.Restore the user's profile.Restore booking history.Recover deleted content or data.Recover credits or services that ended as a result of deletion.A person who wishes to use Sommerfeld again after permanent account deletion may need to create a new account.21. Deleting the App Does Not Delete the AccountRemoving or uninstalling the Sommerfeld application from a phone or other device does not delete the Sommerfeld account or associated information.To delete an account, the user must use the account deletion function or submit a deletion request through one of the methods described in this Policy.22. Service ProvidersWhere appropriate, when information is deleted from Sommerfeld's systems, we may instruct service providers processing information on our behalf to delete or otherwise appropriately handle the affected information.A service provider may independently retain certain information where it is legally required to do so.23. U.S. Privacy RightsCertain United States federal or state privacy laws may provide users with additional rights concerning deletion of personal information.Where such a law applies to Sommerfeld and the relevant user, the deletion request will be handled according to the rights, requirements, limitations, and exceptions provided by that law.Nothing in this Policy is intended to restrict any privacy right provided to a user by applicable law.24. Requests From Parents and Legal GuardiansWhere a deletion request concerns information relating to a minor student, the request should be submitted by the parent, legal guardian, or authorized account holder.Sommerfeld may verify the identity and authority of the person making the request before disclosing or deleting student information.This process is intended to protect student information from unauthorized access or deletion.25. Contact UsUsers may request account or data deletion through:The account deletion function within the Sommerfeld application, where available.The Account Deletion page on the Sommerfeld website.The Contact Us form.Official support channels published through the Sommerfeld website or application.Where possible, requests should be submitted using the contact information already associated with the account to assist with verification.Users should never send their account password or full payment-card information to Support.26. Changes to This PolicySommerfeld may update this Account and Data Deletion Policy from time to time to reflect changes to our services, systems, or applicable legal requirements.The updated version will be published through the Sommerfeld website or application.Any mandatory rights provided under applicable law will apply regardless of the provisions of this Policy.
