Privacy Policy

Last updated: March 25, 2026

1. Information We Collect

When you create an account or use Amiku, we may collect:

  • Account information: Email address, display name, month and year of birth (for age verification), authentication provider (email, Google, Apple, or Telegram)
  • Language preferences: Your native language, English proficiency level, and learning goals
  • Conversation data: Messages you send and receive within the app, including voice messages
  • Usage data: Device type, screen resolution, language, timezone, pages visited, session duration
  • Location data: Approximate location derived from your IP address (country, state, city) — used for timezone detection and analytics only
  • Payment data: Subscription status and payment history (payment details are processed by our payment provider and are not stored on our servers)

2. How We Use Your Information

  • To provide personalized language learning conversations adapted to your proficiency level
  • To remember facts about you across conversations (companion memory system) so your companion can reference previous discussions
  • To verify that you meet the minimum age requirement (13+)
  • To process payments and manage your subscription
  • To send practice reminders and notifications (with your consent)
  • To improve our service through analytics and error monitoring
  • To send you updates about Amiku (you can opt out at any time)

3. AI Processing and Third-Party Services

Amiku uses artificial intelligence to generate companion responses and help you practice English. To provide this:

  • Text generation: Your messages and conversation context are sent to third-party AI language model providers to generate companion responses
  • Speech-to-text: Voice messages you send are processed by a third-party speech recognition service to convert them to text
  • Text-to-speech: Companion messages may be converted to audio by a third-party voice synthesis service

These third-party services process your data solely to generate responses and do not use it for their own model training. We do not share your name, email, or account details with these services — only the conversation content necessary to generate a response.

4. Companion Memory

Amiku companions use a multi-level memory system to remember details you share (your name, interests, native language, etc.) and maintain conversation continuity. This data is stored on our servers and is associated with your account. You can delete individual companions (which deletes their memories) or your entire account at any time.

5. Data Storage and Security

Your data is stored securely using industry-standard encryption in transit and at rest. We use cloud infrastructure providers that comply with SOC 2 standards. We do not sell your personal data to third parties.

6. Cookies and Tracking

We use session storage (not persistent cookies) to track your visit within a single browser session. This data is used solely for analytics and is not shared with advertisers.

7. Your Rights

You have the right to:

  • Access your personal data by contacting us
  • Delete your account and all associated data through the app (Profile > Delete Account)
  • Opt out of marketing communications via the unsubscribe link in any email
  • Disable push notifications and email notifications in Profile settings
  • Request a copy of your data in a portable format

8. Age Requirement

Amiku is intended for users who are 13 years of age or older. We collect your month and year of birth to verify eligibility. If we determine that a user is under 13, their account and data will be deleted promptly.

9. Children's Privacy (COPPA)

Amiku does not knowingly collect personal information from children under 13. If a parent or guardian becomes aware that their child has provided us with personal information without their consent, please contact us and we will delete the information.

10. Consent to AI Data Processing

By creating an account, you explicitly consent to your messages being processed by third-party AI services as described in Section 3. This consent is required to use the service. You may withdraw consent at any time by deleting your account.

11. Data Retention

We retain your data for as long as your account is active. If you delete your account, your personal data, conversations, and companion memories are permanently deleted within 30 days. Anonymized analytics data may be retained for longer.

12. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the "Last updated" date.
