天気のデータWeather data

天気・気温・風・紫外線は MET Norway(ノルウェー気象研究所)の Locationforecast から取っています。データは加工しています(座標を約5kmに丸める、紫外線を雲の量で下げる、天気を「はれ・くもり・あめ・ゆき」の4つにまとめる)。

出典:MET Norway  許諾:CC BY 4.0 / NLOD 2.0

Weather data from MET Norway (Locationforecast 2.0), licensed under CC BY 4.0 / NLOD 2.0. The data has been modified: coordinates are rounded to about 5 km, the UV index is reduced by cloud cover, and conditions are simplified to four kinds (clear / cloudy / rain / snow). This app is not affiliated with MET Norway.

場所と記録のあつかいLocation & data

Your location is used only with your permission, only to fetch the weather for your area and to place the sun and moon. Coordinates are rounded to about 5 km before they leave the device. If you decline, an approximate city-level location from your connection is used instead; IP addresses are not stored. Your save data, pet name and photos stay on your device. No ads, no analytics, no account.

声と音Voice & sound

グラキ君の声はAIで作った音声です。効果音はこのゲームの中で作っています(合成音)。音楽は POTRO が用意したものです。

Graci's voice is AI-generated. Sound effects are synthesized in the game itself.
