Your puzzles are yours. So is your data.

This policy explains how Loomoku: Cozy Sudoku for iPhone and iPad, the browser game at loomoku.com/play and the website loomoku.com handle information. All three are made by Silvergrove Labs LLC ("we", "us", "our").

The short version

Loomoku does not collect personal data. The app's App Store privacy label is "Data Not Collected".
There is no account, no advertising, no analytics and no tracking, and no third-party code in the app or on the website.
Your progress is kept on your device, and in your own iCloud and Game Center accounts if you use them. We cannot see it.
The website sets no cookies. Our web host, Cloudflare, handles the technical data needed to deliver pages.
If you email support, we use what you send only to help you, and we never sell or share it.

Information kept on your device

The app has no account or sign-up. It does not send your gameplay, device identifiers, location, contacts or anything else to us or to anyone else. It does not use the advertising identifier and does not track you across apps or websites, so it never asks for tracking permission. Puzzles are generated on your device and the app works fully offline.

Your progress (levels solved, stars, Tiles, Spools, Hints, streaks and achievements), your unfinished puzzle, the puzzles generated so far and your settings are saved in the app's own storage on your device. Deleting the app deletes this data from the device.

If you have chosen in the Settings app to share analytics with app developers, Apple may give us crash reports and anonymous usage statistics for the app. Apple collects these with your permission, they do not identify you, and we use them only to fix problems. You can change this in the Settings app under Privacy and Security, Analytics and Improvements.

iCloud sync

If you are signed in to iCloud and iCloud is enabled for Loomoku, a copy of your progress is kept in iCloud key-value storage in your Apple Account, so it can follow you to your other devices. Apple stores this copy for you. We cannot see or access it. You can turn iCloud off for Loomoku in the Settings app, under your name, then iCloud.

Game Center

Game Center is Apple's gaming service, and using it is up to you. If your device is signed in to Game Center, the app connects to it after your first win and submits your scores (daily puzzle time, total stars, best streak and player level) and the achievements you earn. Daily times from Gentle mode are not submitted. Apple shows these on leaderboards and to friends according to your Game Center settings, and handles them under Apple's privacy policy. We do not receive your Apple Account details. You can sign out of Game Center in the Settings app at any time.

When you share a Tile or use Export progress in Settings, the app hands that image or backup file to the iOS share sheet, and you choose where it goes. Nothing is sent to us. A backup file holds your progress, settings and any unfinished puzzle, and nothing that identifies you. Once you send a Tile or file somewhere, the service you chose handles it under its own terms.

Reminders and permissions, and your choices

The only permission the app may ask for is notifications, and it asks only when you switch on a reminder in Settings. Reminders are scheduled on your device. No push notification service is used and no notification data reaches us. The app does not use your camera, microphone, photos, contacts or location.

You are always in control: turn reminders, iCloud or Game Center off at any time, export a backup whenever you like, and delete the app to remove its data from your device.

The website and browser game

The website does not use cookies, analytics, advertising, tracking pixels, social media widgets or third-party fonts. All fonts, images, sounds and scripts are served from loomoku.com.

The browser game at loomoku.com/play saves your progress and settings in your browser's local storage, under the key loomoku.web.v1. This data stays in your browser and is never sent to us. You can erase it with Start over in the game's Settings, or by clearing site data for loomoku.com in your browser.

The website is hosted on Cloudflare Pages. Like any web host, Cloudflare processes technical information needed to deliver pages and protect the service from abuse, such as your IP address, browser type and the pages requested. Cloudflare acts as our service provider. We do not use this information to identify or profile visitors. See Cloudflare's privacy policy for how it handles this data. Links to the App Store and other websites take you to services run by others, whose own privacy policies apply.

Information you send to support

If you write to support@loomoku.com, we receive what you choose to send. That may include your email address, the app and system version, your device model, details of the issue, and screenshots. We use it only to answer you and fix the problem. Our email and business-service providers may process it on our behalf. We do not add you to a mailing list, and we do not sell or share your information.

Retention, deletion, and security

We keep support correspondence no longer than 24 months after your request is resolved, unless the law or an open dispute requires us to keep it longer. You can ask us to delete it sooner. Technical logs held by Cloudflare are kept according to Cloudflare's own retention periods. Game data stays on your device, in your browser, or in your own iCloud and Game Center accounts, protected by the security of those systems, and under your control. The website is served only over HTTPS.

Children and international users

Loomoku is a gentle puzzle game that people of any age can enjoy, but it is not directed to children under 13, and we do not knowingly collect children's data through the app. The app collects no personal data from anyone. If you are a parent or guardian and believe your child has emailed us, contact us and we will delete the message.

Support information may be processed wherever our email and business-service providers operate, including the United States. Where the law requires it, we rely on appropriate safeguards for these transfers, such as standard contractual clauses.

California and other regional privacy rights

Residents of California and other US states with privacy laws have the right to know what personal information we hold, to correct it, to delete it, and not to be treated differently for using these rights. We do not sell personal information, we do not share it for targeted advertising, and we do not use it for profiling. Because nothing is tracked, there is nothing to opt out of, and we treat browser signals such as Global Privacy Control as a request we already meet.

If you are in the European Economic Area or the United Kingdom, the GDPR or UK GDPR gives you the right to access, correct, delete, restrict, object to and receive a copy of your personal data, and to complain to your local data protection authority. We rely on our legitimate interests to answer the emails you send us and to deliver and protect the website.

The only personal data we could hold about you is email you have sent us. We will answer any request within one month, or within the time your local law sets.

Changes to this policy

If Loomoku changes in a way that affects your privacy, we will update this page and the effective date above, and update the app's App Store privacy disclosures to match. If a change would ever mean collecting data, we will say so clearly in the app before it happens. Earlier versions are available on request.
