Delete your data
Last updated: July 20, 2026
Master Hachimi stores your reading history and memories only on your device; anonymous records have their free text auto-deleted after 90 days. Deleting your data is entirely in your hands.
How to delete your data
- Open Master Hachimi and go to Settings.
- Tap Privacy, then Delete all history.
- Confirm, and your local reading history is erased from the device.
- Or uninstall the App to remove everything at once.
Types of data and how they're removed
| Data type | What it includes | Removed when |
|---|---|---|
| Reading history | Hexagram, reading text, your question, time, and memories, stored locally | You delete history, or uninstall |
| App preferences | Language and settings, stored locally | You uninstall the App |
| Question sent for a reading | Forwarded to the third-party AI service to generate the reading | Stored under an anonymous ID (collected with use, under the consent you give on first launch), with free text auto-deleted after 90 days; processed by the third-party AI service under its own terms; we have required that it not be used to train its models |
Local data only
Reading history, memories, and settings live on your device. Delete history in Settings, or uninstall the App to remove it all. There is no cloud account; anonymous records keep their free text for at most 90 days (see the Privacy Policy).
Third-party AI service retention
Your question is sent to a third-party AI service to generate each reading. This is a reputable commercial, paid-tier service that we have required not to use your content for training; see the Privacy Policy for details. Email voice@hachimi.ai to request deletion of content already sent.
Older copies inside system backups
Your reading history and memory episodes travel in the encrypted, system-managed backup, so they survive a new phone. Because of that, deleting in the App or uninstalling it only clears this device's copy; it cannot clear a backup Apple or your Android vendor already holds. You remove those yourself: on iPhone, Settings → your name → iCloud → Manage Account Storage → Backups; on Android, the backup section of system settings or Google One. A cast you are in the middle of never enters a backup in the first place.
