Privacy Policy
Effective date: October 19, 2026
NumberLines is a casual merge puzzle game operated by GameLabsNovo. This policy explains how the game handles data.
Data Stored On Your Device
NumberLines stores gameplay progress and settings locally on your device. This can include:
- best score
- best tile
- current run board state
- run statistics
- audio and haptics settings
- purchases cached from Google Play
- tutorial and local preference flags and consent state
This data is used only to make the game work, restore your current run, remember your preferences and purchases, and present your privacy choices.
Data Collection
NumberLines does not require an account and does not collect your name, email address, phone number, contacts, photos, files, precise location, or payment-card information.
NumberLines does not send gameplay progress to a server.
Advertising And Consent
NumberLines uses Google Mobile Ads (AdMob) and Google's User Messaging Platform (UMP). The game shows an interstitial ad after some restarts of a failed run (Retry or New Game) and offers optional rewarded ads for Continue and Undo. Depending on region, consent, device settings, and the ad selected, Google may process device or other identifiers (including the advertising ID when available), device and app information, IP-derived approximate location, ad interactions, and diagnostics for advertising, measurement, fraud prevention, security, and compliance. Personalized ads are shown only with your consent where consent is required (for example in the EEA and UK). UMP collects and communicates privacy choices where required.
You can reopen your privacy options from Settings whenever Google's consent framework reports that the entry point is required. Buying "No Ads" disables automatic interstitial ads; optional rewarded ads remain player-initiated.

Google Play Purchases And Backend Verification
Google Play processes purchases (No Ads, All Adventure Levels, Daily Booster Kit, Complete Bundle). NumberLines sends the product identifier, the Google Play purchase token, and an anonymous authenticated application identity to the studio's purchase-verification backend (hosted on Google Cloud) to verify purchases, restore entitlements, prevent duplicate fulfillment, and process refunds or revocations. The backend stores a purchase record so that paid purchases can be restored and refunds handled; the Google Play purchase token in that record is stored encrypted. Firebase anonymous Authentication and Firebase App Check (Play Integrity) protect this communication. NumberLines does not receive payment-card details.
Analytics
The current version does not include an analytics SDK or a crash-reporting SDK.
If analytics or crash-reporting services are added in a future version, this policy will be updated before that version is released to explain what data those services may process and which partners are used.
Data Sharing And Purposes
Data is processed by service providers only for app functionality, purchase verification, entitlement delivery, advertising, fraud prevention, security, legal compliance, and diagnostics. NumberLines does not sell personal data.
Retention And Deletion
Deleting the app removes the locally stored game data. Verified purchase and anti-fraud records may remain with Google Play and the purchase backend for the period required to deliver entitlements, handle refunds, prevent abuse, and satisfy legal obligations. NumberLines purchases do not expire, so the backend keeps the purchase record without an automatic deletion date so that it can be restored; it is deleted on request unless it must be kept for refunds, fraud prevention, or legal obligations. Short-lived abuse-protection records are deleted automatically within about a day, and database backups are kept for 14 days.
To request deletion of NumberLines data held by the purchase backend:
- Send an email to privacy@gamelabsnovo.com with the subject "NumberLines data deletion".
- Include the Google Play order number of each purchase (it starts with "GPA." and is shown in your Google Play purchase receipt), because NumberLines has no account that could identify you otherwise.
- We confirm the request by email and delete the matching purchase records within 30 days, except data we must keep for refunds, fraud prevention, or legal obligations, which we tell you about in the reply.
Gameplay data is deleted by uninstalling the app or clearing its data. Provider-controlled data (Google Play, Google advertising) is also subject to the provider's controls and legal retention obligations.
Children
NumberLines is not directed to children under the applicable digital-consent age and is not enrolled as a child-directed app. If that changes, this policy will be updated before the change takes effect.
