ECO English Privacy Policy
1. Introduction
ECO English (“ECO English”, “we”, “us”, or “our”) develops and operates the ECO English mobile application (“App”).
This Privacy Policy explains what information we collect, how we collect and use it, when we share it with third-party service providers, how third-party services are used, how we protect information, how long we retain information, and how users can request deletion of their information.
By creating an account or using the App, you acknowledge this Privacy Policy and the applicable consent requests presented within the App.
Where we request specific permission to process or share personal data, that permission is requested separately and before the relevant data is transmitted.
2. Information We Collect
Depending on how you use the App, we may collect and process:
Student name
Email address
Login and authentication information
Learning progress
Quiz results
Speaking quiz responses
Voice recordings submitted through the speaking quiz feature
Information voluntarily provided by the user
Technical and device information necessary to operate and secure the App
Information about how the App and its features are used, where applicable
We collect information through account registration, use of the App, learning activities, speaking quiz submissions, and technical services that support the App.
We only collect and process information reasonably necessary to provide, maintain, secure, and improve the ECO English educational service.

4. Voice Recordings and Third-Party AI Processing
4.1 Speaking Quiz
ECO English includes a speaking quiz feature that allows a user to record a spoken answer.
A voice recording submitted through the speaking quiz may constitute personal data because it is a recording of the user’s voice.
Before a voice recording is transmitted to a third-party AI service, ECO English provides an in-app disclosure identifying:
What data will be sent: the user’s voice recording;
Who will receive it: OpenAI;
Why it will be sent: to convert the spoken response into text for the speaking quiz and associated learning results.
The user must provide explicit permission through the App before ECO English sends the voice recording to OpenAI.
If the user does not provide this permission, the voice recording will not be transmitted to OpenAI.
4.2 OpenAI
ECO English uses OpenAI’s Whisper speech-to-text service to convert submitted speaking quiz recordings into text.
OpenAI is a third-party AI service provider.
When a user provides the required permission and submits a speaking quiz response:
ECO English → Supabase Edge Function → OpenAI speech-to-text service
The information transmitted to OpenAI for this function is the voice recording required for speech-to-text processing.
ECO English does not intentionally send the following account information to OpenAI as part of the speech-to-text request:
User name
Email address
Password or login credentials
ECO English account credentials
User profile information
Learning account information
The resulting transcription is used by ECO English to provide the speaking quiz functionality, feedback, and associated learning results.
OpenAI is not used by ECO English as a general-purpose chatbot within the speaking quiz feature.
OpenAI is used specifically as a third-party service provider for speech-to-text processing.
OpenAI’s API documentation identifies Whisper as a speech-to-text transcription service.
5. Explicit Permission for Third-Party AI Processing
ECO English does not rely solely on acceptance of its general Terms of Use to authorize the transmission of voice recordings to third-party AI services.
Before a speaking quiz recording is submitted for processing, the App provides a specific disclosure explaining that:
the user’s voice recording will be transmitted;
OpenAI is the third-party recipient;
OpenAI will process the recording to provide speech-to-text transcription; and
the transcription will be used for the speaking quiz and learning functionality.
The user must explicitly agree to this processing before the recording is transmitted to OpenAI.
Users may decline this permission. If permission is declined, ECO English will not send the relevant voice recording to OpenAI.
Users may also contact ECO English to request withdrawal of consent or deletion of applicable personal information, subject to applicable legal and operational requirements.
6. Other Third-Party Service Providers
ECO English uses third-party service providers that help us operate the App.
These providers may process personal information only as necessary to provide the services for which they are engaged and subject to appropriate contractual, technical, and organizational protections.
Third-party service providers are required to protect personal information in accordance with applicable privacy requirements and protections that are consistent with the protections described in this Privacy Policy.
Supabase
ECO English uses Supabase for services including:
User authentication
Database storage
Learning progress and quiz data
Application backend services
Secure server-side processing
Supabase Edge Functions
Supabase may process information necessary to provide these backend services.
OpenAI
ECO English uses OpenAI for speech-to-text processing of speaking quiz voice recordings.
Only the information necessary for this particular function is transmitted to OpenAI, as described in Section 4.
ECO English does not sell personal information to OpenAI.
7. Data Security
We take reasonable technical and organizational measures to protect personal information against unauthorized access, alteration, disclosure, or destruction.
ECO English uses security features provided by its backend and service providers, including Supabase, to help protect accounts and data.
Data transmitted between the App, ECO English’s backend services, and relevant service providers is protected using appropriate security measures.
No method of electronic transmission or storage is completely secure, and we cannot guarantee absolute security.
8. Data Retention
ECO English retains account information, learning progress, quiz results, and other information for as long as reasonably necessary to provide the App and its educational services, maintain security, resolve disputes, comply with applicable legal obligations, and enforce our agreements.
Voice recordings submitted through the speaking quiz feature are processed for the purpose described in this Privacy Policy.
ECO English does not intentionally retain voice recordings longer than reasonably necessary for the speaking quiz functionality and supporting processing, subject to technical requirements, service-provider processing, legal obligations, and applicable data-retention requirements.
Where applicable, users may request deletion of their account and associated personal information as described below.
9. Children’s Privacy
ECO English may be used by students, including younger students, under the supervision of a parent, guardian, teacher, or educational institution.
Parents, guardians, teachers, and educational institutions are responsible for ensuring that children’s use of the App is appropriate and supervised and that any required permissions are obtained.
Where the App requests permission to transmit a child’s voice recording to a third-party AI service, the App provides the applicable disclosure and permission request before transmission.
ECO English does not knowingly use children’s personal information for unrelated advertising.
Where applicable law requires additional parental or guardian consent or imposes additional requirements concerning children’s personal information, ECO English will comply with those requirements.
10. Your Choices and Consent
Users may decline the specific permission required to transmit a speaking quiz recording to OpenAI.
If permission is declined, the recording will not be sent to OpenAI.
Users may request deletion of their account and associated personal information by contacting ECO English using the contact information below.
Users may also contact us with questions about how their information is processed or to request withdrawal of consent where applicable.
Withdrawal of consent does not affect processing that occurred before consent was withdrawn, or processing that ECO English is otherwise legally permitted or required to perform.
11. Your Rights and Data Deletion
You may request deletion of your ECO English account and associated personal information.
To request deletion, email:
Please use the subject line:
“User Data Deletion Request”
We will verify the request and, where applicable, permanently delete the requested account and associated data within 7 working days, subject to information that we are required or permitted to retain for legal, security, fraud-prevention, dispute-resolution, or other legitimate purposes.
12. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to the App, our services, third-party service providers, data-processing practices, or applicable legal requirements.
When we make changes, the updated policy will be published on this page and the “Last updated” date will be updated.
Where a material change requires additional consent, we will obtain the applicable consent before processing personal information in the new manner.
