Delete my data
You can request deletion of your Hibiki Voice app account and the data we hold about you by submitting the form below or emailing luca@hibikivoice.com. We confirm your identity via the reply email and delete your data within 30 days. This page covers the Hibiki Voice mobile app; the website itself does not collect personal data from visitors.
What gets deleted
- Your account email address.
- Pronunciation snapshots — reference text, recognized text, overall and per-mora scores, and the calculated tier.
- Lesson and practice-run progress, including completed words, attempts, and the lowest tier reached in each run.
- Monthly pronunciation-assessment quota counters on your account.
- The Apple subscription transaction id we hold, verified via the App Store Server API.
- Deletion requests we are able to identify at our assessment providers, Speechsuper and OpenAI.
What may be retained
- Completed App Store transactions that we are legally required to keep for the refund and tax window, retained in anonymised form.
- Anonymous device quota records used only to prevent trial-quota evasion — these are not linked to your account and are not affected by account deletion.
- Data that our third-party providers (Speechsuper, OpenAI, Google Cloud Text-to-Speech, Apple, MongoDB) retain under their own policies and retention schedules.
