Privacy Policy

ReadingSpace and the Symmetry services

Effective: 2026-09-01Last updated: 2026-08-10
DRAFT — This is a review draft. Please have it reviewed by counsel and complete the company particulars, privacy officer details and effective date before publishing. This document has no legal effect in its current form.

The Company establishes and discloses this Privacy Policy under Article 30 of the Personal Information Protection Act of the Republic of Korea ("PIPA"), so as to protect the personal information of data subjects and to handle related concerns promptly.

This is an educational service used by children. The Company does not use children’s personal information for advertising or marketing, and does not sell it or disclose it to third parties for behavioural analysis. Please read section 6 for how voice recordings captured by the Read Aloud feature are handled.

This English text is a convenience translation. The Korean edition is the operative version and prevails in the event of any conflict.

1. The Company’s role and the scope of this Policy

(1) Depending on how the Service is delivered, the Company acts either as a personal information controller or as an entrusted processor. Different rules apply in each case.

CategoryControllerThe Company’s role
Personal information of students whose accounts were issued by an institution administrator at a school or academyThat institutionProcessor acting on the institution’s entrustment, processing only within its documented instructions

(2) Where the Company acts as a processor, responsibility for establishing the lawful basis for collection and for obtaining legal-representative consent rests with the institution. If a data subject makes a request directly to the Company, the Company forwards it to the institution without delay, acts on the institution’s instructions, and informs the data subject that it has done so.

5. Processing the personal information of children under 14

(1) Where the Company processes the personal information of a child under 14, it obtains the consent of the child’s legal representative under Article 22-2 of PIPA and verifies that consent was given. Verification is carried out by the methods set out in Article 17-2 of the Enforcement Decree: confirmation by SMS to the legal representative’s mobile phone; confirmation by credit card or identity authentication; or having the legal representative indicate consent on a page setting out its content and notifying them by SMS that the Company has confirmed it.

(2) The minimum information needed to obtain that consent — the legal representative’s name and contact details — may be collected directly from the child without the legal representative’s consent under Article 22-2(2), and the Company does not use it for any other purpose.

(3) For institution-managed students, the institution obtains that consent before the account is created, and the Company processes the personal information as its entrusted processor.

(4) For individual student accounts opened by a guardian, the Company verifies the legal representative’s consent directly during account creation.

(5) When informing a child about the processing of their personal information, the Company uses language the child can readily understand.

(6) A legal representative may at any time request access to, correction, deletion or suspension of processing of the child’s personal information, or withdraw consent. The Company will act on such a request and notify the outcome within 10 days of receipt.

(7) In line with the Personal Information Protection Commission’s Guidelines on the Protection of Children’s and Adolescents’ Personal Information, the Company: provides the highest level of privacy protection as the default setting for features children are expected to use; does not design flows that induce a child to disclose personal information in exchange for cash, items or other rewards; and ties learning incentives (stamps, streaks and the like) solely to learning activity, never to the provision of further personal information.

6. Handling of voice recordings

(1) The Read Aloud feature captures audio only when the student actively starts a recording. The Company does not record in the background; the microphone is used only while browser permission has been granted and a recording is in progress.

(2) Recordings are transmitted over an encrypted connection to the Company’s cloud storage and are sent to Microsoft Corporation’s Azure AI Speech (East US region) for pronunciation and fluency assessment. See sections 8 and 9 for details.

(3) Voice recordings are automatically deleted within 30 days of being created. During that period the student can replay their own recordings from the learning report, and their teacher and institution administrator can listen to them for teaching purposes. No other user can access a recording. After deletion, the pronunciation and fluency scores and the transcript are retained as learning records, but the original audio cannot be reconstructed from them.

(4) The Company does not use voice recordings for speaker identification or to generate biometric information, and does not use them for any purpose other than pronunciation assessment and learning feedback.

(5) A legal representative or institution may request deletion of a particular recording or of all of a student’s recordings at any time, and may simply decline to use the Read Aloud feature. Listening, reading, quizzes and all other features remain fully available in that case.

7. Provision of personal information to third parties

(1) The Company processes personal information only within the scope set out in section 3, and provides it to third parties only where Articles 17 and 18 of PIPA permit — such as with the data subject’s consent or under a specific provision of law.

(2) A student’s learning records are made available to the teachers and institution administrators of the institution the student belongs to, for the purpose of teaching, and to the student’s guardian where a teacher uses the sharing feature. This is an inherent function of the Service.

(3) The Company does not sell or rent personal information, and does not provide it to advertising businesses or data brokers.

8. Entrustment of personal information processing

(1) The Company entrusts personal information processing as follows in order to deliver the Service.

ProcessorEntrusted workScope of personal information
Google LLC / Google Cloud Korea LLCCloud infrastructure operation (authentication, database, file storage, serverless execution environment)All personal information processed in the course of providing the Service
Google LLCGeneration of learning summaries and practice questions using generative AI (Gemini)Student name and learning statistics (when a summary is generated); book and question text; the questions typed into the support chatbots
Google LLCGeneration of book narration audio using speech synthesis (Cloud Text-to-Speech)Book text (contains no personal information)
Microsoft CorporationAutomated pronunciation and fluency assessment using Azure AI SpeechRead Aloud recordings and the text of the target sentence
OpenAI, L.L.C.Time-alignment of book narration audio to text (Whisper)Book narration audio (synthesised speech; contains no student voice)

(2) In accordance with Article 26 of PIPA, entrustment agreements specify the prohibition on processing beyond the stated purpose, restrictions on sub-entrustment, technical and organisational safeguards, supervision of the processor and liability for damages; the Company supervises compliance with them.

(3) Where the entrusted work or the identity of a processor changes, the Company discloses the change through this Policy without delay.

9. Overseas transfer of personal information

(1) The Company transfers personal information overseas as follows in order to deliver the Service.

RecipientCountryTime and method of transferItems transferredPurposeRetention period
Google LLC (Firebase / Google Cloud Platform)Primary storage in the Republic of Korea (Seoul region); certain functions are processed in United States and Taiwan regionsTransmitted over the network during use of the ServiceAll personal information processed in the course of providing the ServiceCloud infrastructure operationUntil termination of the processing agreement
Google LLC (Gemini API, Cloud Text-to-Speech)United StatesTransmitted over the network when a teacher generates a learning summary, when practice questions are generated, or when a user types a question into a support chatbotStudent name and learning statistics; book and question text; the questions typed into the support chatbotsGeneration of learning summaries and questions; generation of book audio; searching and checking the relevance of support-chat answersNot used to improve models under the paid service terms; retained only to a limited extent for abuse detection and legal compliance, then destroyed
Microsoft Corporation (Azure AI Speech)United States (East US)Transmitted over the network when a student uses Read AloudRead Aloud recordings and the text of the target sentenceAutomated pronunciation and fluency assessmentProcessed in real time in server memory only; not stored at rest, and discarded as processing completes
OpenAI, L.L.C.United StatesTransmitted over the network during production of book audioBook narration audio (contains no personal information)Time-alignment of audio to textRetained for up to 30 days for abuse monitoring, then destroyed. Not used for model training

(2) These transfers fall under Article 28-8(1)3 of PIPA — entrustment or storage of personal information necessary to perform a contract with the data subject and to enhance their convenience — and separate consent is dispensed with by disclosing the matters above in this Privacy Policy, as that provision permits.

(3) Notwithstanding the above, the Company will stop transferring personal information overseas at the request of a data subject or legal representative. Please contact the privacy officer below. Features that technically depend on such a transfer — pronunciation assessment in particular — will not be available if you do so; listening, reading, quizzes and all other features remain fully usable.

(4) In accordance with Article 28-8(4) of PIPA, the Company contractually requires recipients to apply the protective measures necessary to process personal information safely — including encryption, access control, a prohibition on use beyond the stated purpose, and a prohibition on use for AI model training — and verifies that they do so.

10. Use of AI and automated decision-making

(1) The Company uses artificial-intelligence technology for the following, some of which may constitute fully automated decision-making under Article 37-2 of PIPA.

Automated processingCriteria appliedEffect on the data subject
Determination of reading level (Lexile measure) and level assignmentQuiz accuracy, the difficulty and volume of books read, pronunciation assessment resultsDetermines the range of books available in the library
Calculation of pronunciation accuracy, fluency and completeness scores and WCPMAcoustic and phoneme-level comparison of the recording against the target sentenceDisplayed in learning reports and used as reference material by teachers
Generation of learning summary textA summary of the student’s learning statisticsUsed as the learning comment a teacher shares with guardians

(2) A data subject or their legal representative may request an explanation of such an automated decision. The right of refusal under Article 37-2(1) of PIPA arises where an automated decision significantly affects the data subject’s rights or obligations; the Company accepts requests to refuse each of the decisions above, and to have them reconsidered with human intervention, regardless of whether that threshold is met. Requests are received at the privacy officer’s contact details below, and the Company notifies the outcome within 30 days of receipt.

(3) Teachers and institution administrators can manually adjust a student’s reading level and book range at any time; this operates as a standing means of human intervention in the automated decision.

(4) The Company does not use students’ personal information or learning records — including voice recordings — to train or fine-tune artificial-intelligence models. Such use is permitted only where the institution or legal representative has given express prior consent; that consent is never enabled by default and may be withdrawn at any time. Declining or withdrawing it has no adverse effect on use of the Service.

(5) The Company contractually requires the processors listed in section 8 not to use data received from the Company to train their own artificial-intelligence models.

11. Procedure and method of destruction

(1) Where personal information becomes unnecessary — because the retention period has expired or the purpose of processing has been achieved — the Company destroys it without delay, and in any event within 5 days.

(2) Where information must be retained under law, it is moved to a separate database or stored in a separate location.

(3) Personal information held in electronic files is permanently erased by a method that prevents recovery or reproduction; personal information recorded on paper is shredded or incinerated.

(4) Under the storage lifecycle policy, Read Aloud voice recordings are automatically deleted 23 days after creation — after which they can no longer be played or accessed — and are permanently and unrecoverably destroyed after a further 7-day storage recovery window. The maximum period from creation to complete destruction is therefore 30 days.

12. Rights of data subjects and legal representatives, and how to exercise them

(1) Data subjects may exercise the following rights against the Company at any time.

  1. Request access to personal information
  2. Request correction of errors
  3. Request deletion
  4. Request suspension of processing
  5. Withdraw consent
  6. Request an explanation of, or refuse, an automated decision
  7. Refuse the overseas transfer of personal information

(2) Rights may be exercised by email, in writing, or through features within the Service, and the Company will act without delay. For children under 14, the legal representative may exercise the child’s rights on their behalf.

(3) Where a data subject requests correction of an error, the Company will not use or provide the personal information concerned until the correction is complete.

(4) Rights may also be exercised through an agent, such as the data subject’s legal representative or a duly authorised person, who must submit a power of attorney in the form prescribed by the Notice on Methods of Processing Personal Information.

(5) Because the Company acts as a processor in respect of institution-managed students, requests received are forwarded to the institution and handled on its instructions, except where law requires the Company to respond directly.

13. Measures to secure the safety of personal information

The Company takes the following measures to secure the safety of personal information.

  • Organisational measures — establishment and implementation of an internal management plan; minimisation of staff handling personal information and regular training
  • Access control — role-based permission management, per-account restriction of data access through database security rules, and retention of records of permissions granted, changed and revoked
  • Encryption of credentials — passwords and student PINs are stored using one-way encryption (hashing) that cannot be reversed
  • Encryption in transit and at rest — TLS on all connections and encryption of stored data
  • Retention and tamper-protection of access logs — access logs of the personal information processing system are retained for at least one year
  • Intrusion response — operation of intrusion prevention and detection measures and vulnerability assessment
  • Physical measures — facilities storing personal information are operated in access-controlled cloud data centres under an entrustment arrangement

14. Automatic collection devices: installation, operation and refusal

(1) The Company uses cookies and browser storage to keep users signed in and to remember settings such as language preference.

(2) The Company does not use advertising cookies, behavioural analytics tools, or third-party advertising network tracking technologies.

(3) Users may refuse cookies through their browser settings. Refusing cookies essential to the Service may prevent sign-in from being maintained and otherwise impair use of the Service.

15. Privacy officer and department handling access requests

The Company has designated a privacy officer with overall responsibility for personal information processing and for handling complaints and remedying harm in connection with it.
