Cleo is a Japanese vocabulary study app built around spaced repetition and audio playback. This policy explains what data Cleo collects, why, and your choices.
Information we collect
- Account. Your email address and password, used to create and sign in to your account. Passwords are handled by our authentication provider (Supabase) and are stored hashed; we never see them in plain text.
- Study data. The decks and cards you create or install, and your review history and scheduling (when each card is next due). This is what lets the app track your progress across devices.
How your information is used
- To provide the core service: signing you in, syncing your decks and progress, and scheduling reviews.
- Audio generation. To produce spoken Japanese and English audio, the text on a card is sent to Google Cloud Text-to-Speech, which returns an audio file we cache so it doesn't need to be regenerated. Card text is not personal information and is not used for advertising.
What we do not do
- We do not sell or rent your personal information.
- We do not show third-party advertising.
- We do not use third-party analytics or tracking SDKs to profile you.
Data storage and providers
Your account and study data are stored with Supabase (our database, authentication, and storage provider). Audio is generated by Google Cloud Text-to-Speech. These providers process data on our behalf to operate the app.
Deleting your account and data
You can permanently delete your account at any time from within the app: tap the logo on the Home screen, then Delete account. This removes your account and all associated decks, cards, and study history. The deletion cannot be undone.
Children
Cleo is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children under 13.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
