Your privacy matters

Privacy Policy

Number Lock is made by Granite Gull Studios. You can play without creating an account. The game stores your progress on your device and uses Google AdMob to display in-game advertisements.

What stays on your device

The game saves your level progress, stars, coins, puzzle history and music preferences locally on your device so you can pick up where you left off. These saved game records are not uploaded to Granite Gull Studios. You can remove local saved data through your device's app storage controls. This is separate from the advertising information described below.

Advertising with Google AdMob

AdMob's Google Mobile Ads SDK may collect and share your IP address (which can indicate your approximate location), advertising and other device identifiers, app and ad interactions, and diagnostic information. Google uses this information to deliver and measure ads, maintain its services and prevent fraud. Depending on your settings, consent and eligibility, information may also be used to personalise ads.

AdMob may use device storage and advertising identifiers. Non-personalised ads can still involve data processing for purposes such as measurement and fraud prevention.

Read Google's Privacy Policy and how Google uses information from apps that use its services for details of Google's processing, retention and privacy controls.

Your advertising choices

Advertising options depend on your region, device and consent choices. Where consent is required, it must be obtained before the relevant advertising storage or personal data processing takes place. Any consent message shown in the app explains the available choices and the advertising providers involved.

You can manage advertising identifiers through your device's privacy settings and review Google's ad personalisation settings. Turning off ad personalisation does not necessarily stop ads or all advertising-related data processing. Contact us if you need help with a privacy request or changing a consent choice.

Children

The game does not ask players to submit their name, email address or age. Advertising services may nevertheless process device and usage information as described above. Parents or guardians with questions about a child's privacy should contact Granite Gull Studios.

Changes

If this policy changes, the new version will be posted on this page. Last updated: 1 November 2026.

The hosting provider may process IP addresses and technical request information to deliver and secure the website. See the website privacy notice for information about hosting and contact messages.
