Privacy Policy

Last updated: 27 September 2026

Gravicode ("the app") is a single-player puzzle game. Your privacy is simple to describe because the app is built to need nothing from you.

What the app collects

Nothing. Gravicode does not collect, sell, or share any personal data, and the developer receives none. There is no Gravicode account or sign-in of its own, no analytics, no advertising, and no third-party SDKs.

In-app purchase

Gravicode is free to download, and the first 50 puzzles are free. An optional one-time in-app purchase unlocks all 200. Payment is handled by Apple through the App Store; the developer does not receive your payment details or your Apple Account information.

The app asks the App Store whether you own the full game, including whether you bought Gravicode before it became free, and saves the answer on your device so the full game keeps working offline. Restore purchases in Settings asks the App Store again.

Network

Gravicode is playable offline. The App Store (to show the price and to check, buy, or restore the full game), iCloud progress sync, and Game Center are Apple services that use a network connection when they are available and enabled for your Apple Account.

Data stored on your device

Your level progress, stars, settings (such as sound, haptics, motion, and the daily reminder), and whether the full game is unlocked are saved locally on your device using the operating system's standard storage. Local data is removed if you delete the app; a purchase can be restored afterwards.

iCloud

When iCloud is available for your Apple Account, Gravicode may store a copy of your game progress in Apple's iCloud key-value storage so that progress can merge across your devices. The developer does not operate a server for this data and cannot access it. iCloud is provided and governed by Apple.

Game Center

If you choose to sign in to Apple's Game Center, your leaderboard score (total stars) and achievement progress are handled by Apple under Apple's own privacy policy. This is optional and controlled entirely by you in iOS settings.

Children

The app is suitable for all ages and does not collect any data, from children or anyone else. In-app purchases follow Apple's parental controls, such as Ask to Buy.

This website

The Gravicode pages on fedotoff.top, including this one, are static and have no user accounts. Page visits are counted with Umami, a cookie-free analytics tool run by the developer: it records the page address, referring site, browser, operating system, device type, screen size, language, and approximate location, and does not store IP addresses. Short links under fedotoff.top/go/ count clicks by referring site. The web server keeps standard access logs, including IP addresses.

The site also uses Yandex Metrica, a web analytics service operated by YANDEX LLC (ООО «ЯНДЕКС»). Metrica sets cookies and sends Yandex your IP address, browser and device details, the pages you view, and your clicks, including clicks on links; the developer receives anonymized visit statistics. Yandex processes this data under the Yandex Privacy Policy. You can opt out of Yandex Metrica. The developer does not use any of this website data to target ads.

If this policy ever changes, the updated version will be posted at this URL with a new "Last updated" date.
