Privacy Policy

Last updated: July 12, 2026

This Privacy Policy describes how Voko ("we", "us") handles your information when you use the Voko iOS application and this website.

1. What we collect

  • Voice recordings. When you record a speaking challenge or test, your audio is uploaded over an encrypted connection to our servers so it can be transcribed and scored.
  • Analysis results. Transcripts, scores, skill values, XP, streaks and session history are stored in your account so the app can show your progress.
  • Onboarding answers. Your goals, preferences and practice language, used to personalize your experience.
  • Anonymous account identifier. Voko creates an anonymous account (a random ID) for you. We do not ask for your email, phone number or real name. The first name you optionally enter is used only to address you inside the app.
  • Purchase information. Subscriptions are processed by Apple. Our subscription partner (RevenueCat) receives anonymized receipt data to validate your subscription. We never see your payment details.

2. How your voice is processed

Your recording is processed to produce a transcript (via a speech-to-text provider) and a delivery score (via an AI language-model provider). The audio file is deleted from our storage immediately after the analysis completes. Only the transcript and the resulting scores are retained, in your private account. Our providers process your data as processors on our behalf and do not use it to train their models under our agreements.

3. What we don't do

  • We do not sell your personal data.
  • We do not use your recordings for advertising.
  • We do not require or store your real identity.

4. Data retention & deletion

Voko signs you in anonymously, so there is no account with an email or password to create or log into. Your results are stored under a private anonymous identifier tied to your device. Your audio recordings are deleted from our storage right after each analysis. To have the stored data linked to your device deleted, email us at voko-app@outlook.com and we will remove it.

5. Third-party services

Voko uses: Google Firebase (authentication, database, storage — data hosted on Google Cloud), ElevenLabs (speech-to-text), OpenAI (delivery scoring), Apple App Store & RevenueCat (subscriptions). Each processes only the data needed for its function.

6. Children

Voko is not directed at children under 13, and we do not knowingly collect data from them.

7. Your rights

Depending on where you live (e.g. GDPR in the EU, CCPA in California), you may have rights to access, correct, export or delete your data. Because Voko uses anonymous sign-in with no account to log into, email us at voko-app@outlook.com to exercise these rights and we will act on the data tied to your device.

8. Changes

We may update this policy; material changes will be reflected on this page with a new "Last updated" date.
