Chocolingo ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the Chocolingo mobile application (the "App"), an English language learning platform designed for Mongolian speakers.
By using the App, you agree to the collection and use of information in accordance with this policy.
The App can be used in two modes:
Linking is required to use the AI Speaking Coach feature (see Section 1.3) and is recommended to back up your progress across devices.
The AI Speaking Coach feature processes voice and text data through third-party AI services. When you use this feature:
The AI Speaking Coach is rate-limited to 5 conversation rounds per user per day. We may disable the feature at any time without notice for maintenance, abuse prevention, or cost management.
We rely on the following third-party services to operate the App:
| Provider | Purpose | Data Sent | Location |
|---|---|---|---|
| Supabase | Authentication, database, backend | All app data | US |
| Apple | Sign in with Apple | Authentication tokens | US |

| Deepgram | Speech-to-text (Speaking Coach) | Audio recordings (not retained) | US |

| ElevenLabs | Text-to-speech (Speaking Coach) | Response text only | US |
We use the information we collect to:
Your data is stored using Supabase (PostgreSQL) with row-level security enabled on all database tables. We use HTTPS/TLS encryption, role-based access controls, server-side rate limiting, and input validation.
While we take reasonable precautions to protect your data, no method of electronic storage or transmission is 100% secure.
The App is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13.
The AI Speaking Coach feature is intended for users aged 13 and older. Before using the AI Speaking Coach, users are required to confirm they are 13 or older. If you believe a child under 13 has used the AI Speaking Coach feature, please contact us and we will delete the associated data.
If you are between 13 and 18 years of age, you should review this Privacy Policy with a parent or guardian before using the App.
The AI Speaking Coach uses generative AI, and despite our safeguards, may occasionally produce inappropriate or inaccurate content. You can report any AI response by tapping the report icon visible on each AI message. Reports are reviewed by us and used to improve the system. We may suspend the feature for users who abuse the reporting mechanism or who attempt to misuse the AI feature.
We do not sell your personal information. We may share your information only in the following circumstances:
You have the right to:
To exercise any of these rights, contact us at support@chocolingo.com. We will respond to requests within 30 days.
We retain your personal data for as long as your account is active. If you delete your account, we will delete or anonymize your personal data within 30 days, except where retention is required by law.
Anonymized, aggregated data (such as overall usage statistics) may be retained indefinitely.
The App stores certain data locally on your device using SQLite and device storage. This local data is not transmitted to our servers until you are connected to the internet. You can clear local data by uninstalling the App.
We may update this Privacy Policy from time to time. We will notify you of significant changes via the App. Your continued use of the App after changes are posted constitutes your acceptance of the revised policy.
