Privacy Policy

Effective date: November 7, 2026

This Privacy Policy explains how Aevatrix ("we," "us," or "our") handles information when you use Letterlume (the "Game").

To delete game data or request deletion of support correspondence, see Your choices and data deletion.

Game saves

Your level progress, stars, coins, hints, the word language you chose, daily puzzle streak, daily rewards and goals, achievements, styles you own, the level you are playing and your settings are stored on your device. Letterlume does not require an account to play. In versions configured for Google Play Games, successful Google authentication automatically enables cloud saving unless you previously turned it off. Settings → Cloud save shows its status and lets you connect, sync or turn it off. Turning it off keeps the existing Google cloud copy; it does not delete it. Automatic Android cloud backup is disabled in this build. Device-transfer behavior may depend on your Android version and device manufacturer; restoration is not guaranteed. Without a successful cloud save, do not rely on recovering progress after uninstalling, clearing app data or changing devices.

Google Play Games cloud saves

Configured versions use your Play Games player identifier to bind a saved game to your Google profile. The cloud copy includes gameplay progress, coins, hints, rewards, cosmetics, the chosen word language, in-progress puzzles and purchase-grant records needed to prevent duplicate rewards. Google stores this copy using its Saved Games service. Conflicting copies require you to choose one whole save; coin balances are not combined. A cloud copy cannot grant Letterlume Pass: purchase ownership is restored through Google Play Billing. The game may retain a device-local copy before replacing progress. Google manages its own profile and service records under its privacy policy. The Play Games SDK also collects analytics and diagnostics to improve its stability and products.

App updates

Google Play may supply update availability, version and download status. The game offers updates through Google's own update or store flow. Installing a critical update may be required to continue; normal updates can be postponed. No saved-game data is sent to a separate update server.

Word lists and meanings

All boards, word lists and word meanings are included in the Game and work offline. Looking up a word's meaning happens on your device; nothing you find or look up is sent to us.

Reminders

After you finish your first level, Lumi, the Game's firefly, asks whether you would like reminders. If you allow them, the Game schedules a small number of notifications on your device, for example a note that your daily reward or a new daily puzzle is waiting. To pick a sensible time, the Game remembers on your device the hour of day you usually play. Reminders are created and shown entirely on your device; no push-notification service is used and nothing is sent to us. You can turn reminders off at any time in the Game's Settings or in Android's notification settings.

Gameplay analytics and diagnostics

Letterlume does not transmit your gameplay progress or gameplay analytics to our servers and has no separate gameplay analytics or crash-reporting service. Google Mobile Ads (AdMob) processes its own diagnostics as described below.

Ads and purchases

Letterlume shows ads and offers in-app purchases. Coins and hints can also be earned through gameplay, daily rewards and goals.

Ads. Ads are served through Google Mobile Ads (AdMob). Its software collects and shares device identifiers (including the advertising ID), app interactions, diagnostics, and IP-address information that can be used to estimate approximate location, for advertising, analytics and fraud prevention. Where the law requires it, Google's consent form asks for your choices before ads are shown, and Settings offers Privacy choices to change them. Reward videos are always optional.

Purchases. In-app purchases (the Letterlume Pass, coin packs and offers) are processed through Google Play Billing. We never receive your payment details. The Game processes product identifiers, purchase status and purchase tokens on your device to deliver purchases, verify ownership and prevent duplicate grants. When you tap Buy, the Game remembers on your device what you chose (for example which offer, or whether coins are doubled), so the purchase gives exactly that; nothing extra is sent to Google Play. Google handles purchase records under its own policies.

Connection check. Free play needs an internet connection: when a level is about to start, the Game reads whether your device is online. It only reads this on your device and sends nothing to us. With the Letterlume Pass you can play offline.

Google retains billing and advertising information under its own policies, including the Google Privacy Policy.

Online legal pages

The Game includes offline copies of this policy and the Terms, which you can read under Settings without a connection. If you choose to open their public web versions or the support email link, your phone's browser or email app opens them outside the Game. The website's hosting provider, Railway, may process your IP address, browser information and request logs to deliver, secure and operate those pages. This is separate from gameplay, and the Game does not send your saved progress to that website. The legal pages do not include advertising or analytics scripts.

Sound and device features

The Game plays sound effects and optional music and can use your device's vibration. These features work entirely on your device and do not collect information. The Game does not use your camera, microphone, contacts or precise location.

Storage and retention

Device-local data remains until it is cleared or the app is uninstalled. "Reset progress" in Settings erases your game progress on this device. We cannot remotely access your device-local game save. Configured versions can restore a successfully saved Google Play Games copy through the same Google profile; restoration still requires a working connection and a valid saved game. Any device-transfer copies managed outside the Game are controlled by your device and operating system. If you contact support, we receive your email address, message and any files you choose to send. A message sent with the Game's Feedback card also contains the topic you picked, the Game's version, your Android version, your phone's maker and model, and the highest level you reached; you see all of it in your email app before you send it. We use them to respond, investigate the issue and handle related follow-up. We retain this correspondence only as long as needed for those purposes or to meet applicable legal obligations. To request deletion of support correspondence, email support@aevatrix.com. Any information that must be retained for a legal obligation is kept only for that purpose.

Data protection

Game saves are kept in the app's local storage, within Android's app sandbox. Their protection also depends on your device security and operating system. Support correspondence is handled through our email provider, separately from the Game. Do not send passwords, payment-card details or other unnecessary sensitive information. No storage or communication method can guarantee absolute security.

Children's privacy

Letterlume is intended for users aged 13 and older and is not directed to children under 13. We do not knowingly collect personal information from children under 13. No account, email address or real name is required to play.

Your choices and data deletion

You can change the word language, sound, music, vibration, Lumi's tips and reminders in Settings, block notifications in Android's settings, reset your progress in Settings, and erase locally stored game data through Android's app settings. Settings offers Privacy choices where your region requires them, and you can reset or delete your advertising ID in your device settings. Clearing local storage does not cancel Google Play purchases; the Letterlume Pass can be restored with Restore. Google Play Games data is managed separately through your Google account and Play Games settings, where you can delete saved game data. Turn off cloud saving in Letterlume before deleting that data if you do not want the game to create another copy. Reset progress resets this device’s progress and may sync that reset while cloud saving is enabled; it does not independently delete Google’s stored data. Any operating-system device transfers are controlled separately. We cannot remotely access or delete your device-local save; you control its deletion on your device. You can request deletion of support correspondence using the contact address below.
