Privacy Policy
How Nishiki handles information about your settings, weather requests, purchases and support enquiries.
Effective / last updated
1. Operator and scope
Yoshiki Nitta operates the Nishiki app, its weather service and this website. There is no app account registration, advertising or advertising tracking.
2. Information stored on your device
Koi selections and counts, selected cities, recent and favourite places, preferences and onboarding completion are stored on your device. The latest weather snapshot for the selected place is cached for up to 24 hours from retrieval for startup display, and removed on expiry or a change of place. The app does not build a weather history.
The app does not access GPS or device location services. A city you select is not necessarily your current location. Koi settings and the list of favourite places are not uploaded to our servers. OS backups may include app settings.
3. Weather requests and logs
Place search terms and selected place or weather region identifiers are sent to our API at api.weatherwindow.space. Cloudflare also receives network data such as IP address, request URL, time, request outcome and client information. Cloudflare derives an approximate country or city from the IP address as network metadata for delivery and security. This is not a GPS location from your device. Place search uses the network. Please do not enter passwords or detailed personal addresses in search.
Cloudflare, Inc. hosts the weather API. Request and error logs support delivery, troubleshooting, security and usage management. They may include URLs containing search terms or selected places and network metadata. As information can be associated with an IP address, we do not treat all request data as anonymous. We do not use it for advertising, cross-app tracking or selling data.
Our server requests weather from Apple Inc.'s WeatherKit using a representative location for the region. It does not forward your GPS location, search terms or email address to WeatherKit. Weather is cached by region and we do not create individual user profiles.
4. Support and purchases
If you email us, we use your email address, sender name if provided, message and voluntary attachments to respond, investigate issues and handle rights requests. Copying diagnostic information in the app does not send it to us. Review it before sending and remove unnecessary personal information. Support email is processed through services including Apple iCloud Mail.
Apple processes purchases, payments and refunds in the App Store. We do not obtain payment card details or Apple Account passwords in the app. When you buy an additional koi variety or the All Varieties Pack, Apple sends RevenueCat information such as the product and transaction identifiers, price, currency, and purchase or refund date. We use RevenueCat to review in-app sales and refunds. We use Apple’s reports for paid app sales and downloads.
5. This website and external links
Vercel Inc. hosts this website and processes technical information such as IP address, URL, browser, referrer and time for delivery and security. We do not add advertising tags, behavioural analytics or a contact form to this site. External sites and your email provider also apply their own privacy policies.
6. Retention and security
Device settings remain until deletion of the app or relevant device data. Ordinary Workers logs are retained for up to seven days under the service configuration. Limited records may be kept longer where necessary to investigate an incident or handle legal claims. Support correspondence is normally deleted within one year after resolution, unless a legal obligation or dispute requires longer retention. Infrastructure providers may retain their own security records under their policies.
We use measures including encrypted transmission and restricted administrative access appropriate to the information involved.
7. Providers and international processing
We use the providers above as needed to operate the service. They are based in the United States and other countries, and processing may occur outside your country. We follow applicable legal bases and safeguards for processing and transfers. We do not sell personal information or disclose it without consent except as permitted by law.
Where applicable, processing is based on providing the requested service, legitimate interests in security and support, legal obligations, or consent where required.
8. Your choices and rights
Deleting the app removes its local settings. Manage any OS or iCloud backups separately. We cannot recover data stored only on your device.
Contact shirohebi.i@icloud.com to request access, correction, deletion or restriction as provided by applicable law. We may verify your identity. We may be unable to locate a record when we hold no information connecting it to you. Depending on your jurisdiction, you may also have rights to object, obtain portability, withdraw consent or complain to a supervisory authority.
9. Children and changes
Minors should obtain parental consent or assistance with purchases and support when required by law. The app does not ask children to submit personal information. We will update the revision date when this policy changes, provide advance notice of material changes where appropriate, and obtain consent where required.
