Chroia Works (address: Hamamatsucho Dia Bldg. 2F, 2-2-15 Hamamatsucho, Minato-ku, Tokyo 105-0013, Japan; “we” or “us”) sets out below how information is handled in the application “Oiko — 家計簿” that we provide (the “App”) and on this website.
All data you enter or record in the App (such as income and expense records, fixed costs, budgets, and tags) is stored on your device (in the App’s storage area). We do not collect, view, or retain this data.
The App does not send your record data to our servers or to any other external destination. We do not conduct usage analytics (traffic analytics or behavioral tracking), and we do not display advertisements.
This website is delivered using GitHub Pages (GitHub, Inc.). Because of how this delivery works, technical information such as the IP address you connect from may be processed by GitHub. For details, please refer to the GitHub General Privacy Statement.
Because your record data exists only on your device, it may be lost in cases such as deletion of the App or the reset, failure, or replacement of your device. We recommend making regular backups with the export function under 設定 (Settings) → 備え (Backup) in the App. We have no means of restoring lost data.
Your record data is stored only on your device, and we do not receive any of it. You therefore do not need to ask us to delete it, and we are also unable to delete it. To erase your data, delete your records from 設定 (Settings) → 削除 (Delete) in the App, or delete the App from your device. Note that 全データを削除 (Delete all data) erases your records, fixed costs, and “no spending today” marks; your budget, colors, and display settings remain. To erase everything, including settings, delete the App from your device. Deleting the App also erases the records on your device. Deleted records cannot be restored, so please export any records you need from 備え (Backup) before deleting.
If you purchase paid features of the App, payment is made through the App Store (Apple) system, and we do not obtain payment information such as credit card numbers. The App may refer to purchase information provided by the App Store in order to confirm your purchase status.
For inquiries about this Policy or the App, please contact info@chroia.jp. We use the email address and content of your inquiry only to reply to you and to investigate bugs. If you ask us to, we will delete your inquiry emails.
We may revise this Policy as necessary. If there are important changes, we will announce them on this page.
