Privacy Policy

TiKi English · Effective date: October 6, 2026

This policy describes how TiKi English collects, uses, shares, retains, and protects information when you use our English-learning website and Android application.

1. Who we are

TiKi English is an AI-assisted English-learning service available through our websites and Android application. For privacy questions or requests, contact tikienglish.com@gmail.com.

2. Information we process

Depending on the features you use, information may include your name, email address, account identifiers, selected language and learning level, lesson history, saved vocabulary, writing submissions, chat messages, role-play transcripts, speaking audio, pronunciation feedback, images or documents you choose to upload, technical diagnostics, and subscription status. Some features are optional and only process information you choose to provide.

3. Microphone, camera, and uploads

Speaking exercises may request microphone permission to capture speech for transcription, AI feedback, and interactive conversation. Camera or file-upload features may process images or documents you submit for lessons. Microphone access is requested when you use speaking features. Speech may be sent to OpenAI for live responses or transcription. Saved lessons can include learner-only audio and recordings of both sides of an AI conversation, stored in Supabase for review. You can deny permissions or revoke them in device settings, but the related features may not work. Do not upload sensitive personal information unless necessary.

4. How information is used

We use information to authenticate accounts, provide lessons and AI responses, assess pronunciation and writing, save learning progress, personalize practice, provide customer support, maintain security, troubleshoot problems, and administer memberships. AI-generated feedback can be inaccurate and should be reviewed critically.

5. Service providers and sharing

To deliver the service, information may be processed by providers supporting hosting, databases, authentication, AI processing, speech services, analytics, customer support, and payment processing. For example, prompts, speech, and uploaded learning materials may be sent to AI or speech-processing services to provide requested features. Payment providers may process transaction and subscription information. We do not publish your private learning content to other users without an applicable feature or your action. TiKi English uses OpenAI for AI responses, live voice conversations, transcription, and learning feedback; Supabase for account authentication, learning records, and uploaded file and audio storage; and Stripe for website payments. Hostinger hosts the website. Support email services process messages you send us. When enabled, email delivery services also process service notifications.

Browser storage and learning access

The website uses browser local storage for sign-in sessions, language choices, and some learning progress and preferences. Clearing browser storage may remove locally stored information and sign you out; it does not delete server-side data. If you join a teacher class, submit work, or use a sharing or community feature, the relevant teacher or chosen audience may access the information made available by that feature.

6. Payments and subscriptions

Website purchases are processed through Stripe. Payment credentials are submitted to the payment processor; TiKi English receives account and purchase information such as customer identifiers, transaction references, amount, currency, plan, and subscription or cancellation status to manage access and billing. This policy does not represent that Google Play billing is currently implemented. Cancelling a subscription and requesting account deletion are separate actions.

7. Storage, security, and retention

We use reasonable technical and organizational measures intended to protect information, including encrypted connections where supported and access controls. No online system can guarantee absolute security. We retain account information and saved learning content, including saved conversations and recordings, until you request deletion, unless you remove content using an available feature. We do not currently apply an automatic expiry period to this saved content. When processing a verified deletion request, we delete the account and associated learning content from our active systems, subject to records needed for legal obligations, billing, dispute resolution, and fraud prevention. We explain applicable exceptions when responding. Backup copies may remain until replaced or expired under the hosting provider’s backup lifecycle; deletion from backups is not immediate. AI and payment providers may retain information under their own applicable service policies and legal obligations.

8. Your choices and deletion requests

You may contact tikienglish.com@gmail.com to request access, correction, export, or deletion of your personal information and account. Include the email address associated with your account; we may need to verify ownership. We will explain any information we must retain for legal or billing reasons. Visit our account and data deletion page for instructions. Requests are handled manually by TiKi English support; the email link does not automatically delete your account. You do not need to sign in to view the instructions. Please do not send passwords or payment card details.

9. Children and education

TiKi English offers educational content. If children use the service, a parent or guardian should review the available features and privacy practices. Parents or guardians can contact us about a child’s account or information, including to request deletion. Teachers and schools should obtain any necessary permissions before submitting learner information.

10. International processing

Depending on the service providers used, information may be processed or stored in countries other than your own, where different privacy laws may apply.

11. Updates to this policy

We may update this policy when the service or our data practices change. The updated version and effective date will be posted on this page.

12. Contact

Privacy inquiries and account deletion requests: tikienglish.com@gmail.com. Website: https://tikienglish.com.

Optional phone verification

You may optionally verify your phone by SMS for account support and membership communication. You may skip without losing access to learning. We store your confirmed number in Supabase Auth, and a reminder date if you skip. SMS delivery providers process your number and verification message to deliver the code. We do not store the code in learning records.

Promotional messages require a separate, optional choice. You can withdraw that choice under My account → Phone verification & preferences. Account deletion also removes your phone preference record. Contact support through Help & Feedback for phone data requests.

Xác minh số điện thoại không bắt buộc

Bạn có thể xác minh qua SMS để hỗ trợ tài khoản và thông tin thành viên, hoặc bỏ qua để tiếp tục học. Số đã xác minh được lưu trong Supabase Auth; khi bỏ qua, hệ thống lưu ngày nhắc lại. Nhà cung cấp SMS xử lý số và tin xác minh để gửi mã. Tin quảng cáo cần sự đồng ý riêng; bạn có thể rút lại trong Tài khoản → Xác minh số điện thoại và tùy chọn.
