Account & your data
Last updated: August 25, 2026
Master Hachimi has no accounts, so you use it without signing in and there is no account to delete. Your reading history is stored only on your device. This page explains exactly what is stored, where, and how to clear it.
How to clear your data
- Open the app and switch to the Me tab.
- Tap Privacy and data, then Delete data on this device.
- Tap Delete all to confirm; your history, drafts, and what the Master remembers are cleared in one go.
- Or simply uninstall the App to remove everything at once.
What's stored, and where
| Data | Where it lives | Removed when |
|---|---|---|
| Reading history (hexagram, reading, question, time) | On your device only | You delete history, or uninstall |
| Language / settings | On your device (local preferences) | You uninstall the App |
| Your question (during a reading) | Sent to our server, forwarded to the third-party AI service | Stored under an anonymous ID (collected with use, under the consent you give before your first actual online reading), free text auto-deleted after 90 days; the third-party AI service processes it under its own terms (see the Privacy Policy) |
No server-side account
Our server casts the hexagram and hands your question to the third-party AI service to write the reading. There is no account. Records are stored under an anonymous install identifier with free text auto-deleted after 90 days; you can reset the anonymous ID under Me → Privacy and data at any time.
Data sent to the third-party AI service
DeepSeek Open Platform generates online readings; section 3 of the Privacy Policy lists the data and purposes. Received content is processed under applicable service terms. Withdrawing App consent does not delete content already sent. Contact voice@hachimi.ai for help requesting deletion.
