Last updated: February 24, 2026
Information You Provide
When you use HaikuOne, you may provide content such as haikus, mood selections, and writing metadata (for example dates and writing frequency).
How Data Is Used
- To store and display your entries inside the app.
- To generate on-device insights and writing patterns.
- To provide app functionality, including optional premium features.
- To allow manual, non-automated export of your data when you choose to export from within the app.
Purchases and Billing
Subscriptions and billing are handled by Apple through the App Store. HaikuOne does not process your full payment card details directly.
Data Sharing
HaikuOne does not sell your personal data. Haiku content is stored only on your device in the current version. No third-party analytics or crash SDKs are used; only Apple's platform-level services may process technical diagnostics.
Data Retention and Control
Your entries remain available to you inside the app until you delete them. You can remove entries at any time and export data manually using the app's export functionality.
Future iCloud Backup
A future version is planned to support iCloud saving so users can avoid data loss and keep their data tied to their own account.
Children's Privacy
HaikuOne does not knowingly collect personal information from children.
Contact
For privacy questions, users can contact the developer through the app using Contact Support.
