Privacy Policy

Who we are

Lumenlings is published by Plastic Drum Productions, the controller of the data described here. For privacy questions or requests, email support@lumenlings.com.

Your game data

Progress, Daily Challenge results and streaks, hints and settings are stored on your device. There are no player accounts, and we do not receive your saved game. When you finish a puzzle, the game sends us an anonymous result so that it can tell players how their solve compares: which puzzle it was, how long it took, how many incorrect moves and hints, whether an extra life was used, the date, the app version and whether the device is Android or iOS, with a random identifier created on your device for this purpose only. It is not your advertising ID, is not linked to your name, account or purchases, and is deleted when you clear the app's storage or uninstall. We do not store your IP address with results. You can turn this off at any time in Settings → About → Share results; results still waiting on your device are then discarded. We do not use a separate analytics or crash-reporting service. Google services can process data as described below.

Backup and deletion

Android may include progress in encrypted Google account backups and device transfers, depending on your device and backup settings. The local Remove Ads ownership cache is excluded; purchases are checked with Google Play. Clearing app storage deletes the local game data. Uninstalling removes the local copy, but eligible progress may return from a backup when you reinstall. Manage or delete backups through your device or Google account backup settings. We do not hold a copy to restore for you.

Advertising

Google AdMob provides banners while playing, occasional full-screen ads between puzzles, and optional rewarded ads for hint refills or an extra life. Its SDK may collect your IP address (including approximate location), advertising and app-set identifiers, device information, app/ad interactions and diagnostics for advertising, measurement and fraud prevention. SDK data is encrypted in transit. Where required, the consent form explains Google and its advertising partners before ads load. Change or withdraw your choice in Settings → Privacy Preference where that option is available; you can also manage the advertising ID in Android Settings. Google describes its use, recipients and retention at https://policies.google.com/privacy and https://policies.google.com/technologies/partner-sites.

Purchases and reminders

Google Play handles Remove Ads payments and purchase records. We do not receive your card, billing address or Google account details; the app checks purchase ownership and caches its entitlement state locally. Daily reminders are optional notifications scheduled on your device for 9:00 AM local time. No push token or reminder data is sent to a server. Turn them on or off in Settings → Daily reminder; your device's notification permission also applies.

Sharing and support

Share images and optional diagnostic exports are created on your device. Temporary share files are cleaned up after sharing. Only the app you choose receives the file, under its own privacy policy. Support and feedback buttons prepare an email you can review and edit. If you send it, we receive your email address, message and any details or attachments you include, such as the puzzle, app version or diagnostic code. We use these to respond and investigate problems. Our support email is hosted by Google. Nothing is emailed automatically.

Legal bases and retention

Where UK or EU data protection law applies, we rely on providing the game and purchases to perform our contract with you, legitimate interests to respond to support requests and resolve faults, and consent where required for advertising. Game data remains on your device until removed; backup retention depends on your backup settings. Support correspondence is kept only as long as needed to resolve your request and meet legal obligations. Google manages its own advertising and purchase records under its policies.

Security and international processing

Game data is kept in app storage protected by your device. Support correspondence is accessed to handle support, and is not sold. Google services, including support email, may process information outside your country. Google's transfer safeguards, including adequacy decisions and standard contractual clauses, are explained at https://policies.google.com/privacy/frameworks.

Your rights

Depending on applicable law, you may request access, correction, deletion, restriction or portability of personal data, object to processing, or withdraw consent without affecting earlier lawful processing. Contact support@lumenlings.com for data we hold, including support emails. For data held by Google, use its privacy controls or contact Google; we can help identify the relevant service. You may complain to your local data protection authority, including the UK's Information Commissioner's Office at https://ico.org.uk/make-a-complaint/.

Children and updates

Lumenlings is not directed at children, and we do not knowingly collect personal information from them. Contact us if you believe a child has sent us personal data. The date above identifies the current policy; updates are available in the app and on the privacy-policy page.
