Banshaku Privacy Policy
Effective date: November 14, 2026
Last updated: November 14, 2026
StratAIX ("we", "us") respects your privacy. This policy explains how we handle information about you in connection with the iOS app "Banshaku: Drink & Food Journal" (Japanese name "晩酌帳"; the "App"). The App does not send information about you to our servers.
1. Scope of this policy
This policy applies to your use of the App. Your use of our website (strataix.net) is governed by the StratAIX Website Privacy Policy.
The App uses Apple's App Store for distribution and purchases. Apple's handling of information is governed by Apple's Privacy Policy.

3. Information stored on your device
The App stores the following information that you enter only on your device. We do not send this information to our servers, and we cannot see it.
- Entries: drink name, type, date, how it was served, dishes, rating, note, and any added details
- Photos: photos of labels and the like that you take or choose
- Shelf: names of bottles you have at home, number of bottles, how much is left, and the date opened
- Settings: your choice of card style and other app settings
The information is kept in the App's own storage area (a database and photo files in the Application Support directory) and in UserDefaults. Other apps cannot read this area. The App has no syncing feature such as iCloud sync.
Before saving a photo, the App redraws it so that its longer side is at most 1,600 pixels. Location and other capture information (such as EXIF data) is not saved.
If you delete the App, this information is removed from your device. Whether data on your device is included in iCloud or other backups depends on your OS and account settings.
4. Camera and photos
The App uses the following iOS features only in these cases. Each one works only after you take an action, and any photo obtained is stored only on your device as described in Section 3.
- Camera: used to take a photo of a label or the like when you choose "Take photo" on the entry screen. iOS asks for your permission the first time.
- Choosing a photo: when you choose "Choose photo", the App shows the iOS photo picker. The App receives only the photo you pick and does not ask for access to your whole photo library.
- Saving to Photos: used to add the image of an entry's card to your photo library when you save it. The App asks for add-only permission and does not read your photo library.
You can change these permissions at any time in the iOS Settings app.
5. Sharing and export
Only when you take an action does the App pass the following to the iOS share sheet. You choose where it goes; the App never sends anything automatically. The recipient's handling of the information is governed by the recipient's own terms.
- Card: an image combining the photo, date, drink name, how it was served and dishes, rating, and the app name. Your note is not included.
- Export: a file (ZIP) containing your entries in a spreadsheet-readable format (CSV) and your photos. Temporary files used for the export are deleted from your device after the share sheet is closed.
6. In-app purchase
The App uses App Store in-app purchase. We sell one one-time (non-consumable) product that unlocks the add-on features (Shelf, Pairings, and Your taste). There is no subscription.
Payment, refunds, and receipts are all handled by the App Store. We do not collect or keep credit card numbers or other payment information. What the App receives from the App Store is the result of verifying whether a purchase is valid.
7. Information we do not collect
The App does not collect:
- Your name, address, phone number, or email address (except when you contact us as described in Section 10)
- Location information
- Contacts, calendars, microphone, or health information
- Advertising identifiers or other identifiers used to track you
- Payment information
The App has no account registration, usage analytics, advertising, or tracking. The App has no feature that communicates with our own servers. The App communicates externally only when it uses the App Store for in-app purchases (Section 6) and when you choose to share (Section 5).
The App is not designed to record or manage how much or how often you drink, and it does not collect health information.
8. Sharing with third parties
We do not sell information about you. Because we do not hold the information you enter in the App, we do not provide it to third parties. To the extent necessary to provide the App, the following company handles information.
| Company | Location | Role | Examples of information handled |
|---|---|---|---|
| Apple Inc. | United States | App Store (distribution, purchases, billing) | Result of purchase verification |
We may disclose information we hold where necessary to respond to a legal request, to protect the rights or safety of users or others, or to deal with fraud.
9. Retention
The information in Section 3 is kept on your device until you delete the entries in the App or delete the App.
Information processed by Apple Inc. is kept according to its own policies.
10. Your rights
Because the information in Section 3 is stored only on your device, you can delete it at any time by deleting entries in the App or by deleting the App.
If the GDPR applies to you, you may exercise your rights of access, rectification, erasure, restriction of processing, objection, and data portability, subject to the conditions of applicable law. You also have the right to lodge a complaint with the data protection supervisory authority where you live or work, or where you believe a violation occurred.
If you are in Japan, you may request notification of the purpose of use, disclosure, correction, addition, deletion, suspension of use, erasure, or cessation of provision to third parties, subject to the conditions of the Act on the Protection of Personal Information and other applicable laws.
To exercise your rights, contact us at [email protected]. If we cannot respond to a request because we do not hold the information on your device, we will explain why.
11. Age
The App is for keeping records related to alcoholic drinks. It is not intended for people below the legal drinking age in their country or region. We do not knowingly collect information from children under 13.
12. Changes to this policy
We may change this policy in response to changes in law, in the App's features, or in how we handle information. We will post the updated policy on this page and update the "Last updated" date.
