Gridlock ("the app," "we," "us") is a math puzzle game developed by Nicholas Nunziata. This policy explains what information the app handles and how. By using Gridlock you agree to this policy.

Information we handle

Stored only on your device. Your best scores and game settings are saved locally on your device using standard iOS storage. This data never leaves your device and is not transmitted to us or anyone else. Deleting the app removes it.

We do not collect personal information ourselves. Gridlock has no accounts, logins, or sign-ups. We do not ask for or collect your name, email, contacts, photos, or location.

Advertising (Google AdMob). Gridlock is free and supported by ads served through Google AdMob. To serve and measure ads, Google's advertising technology may collect and process information such as your device advertising identifier (IDFA/IDFV), IP address, device type and settings, and your interactions with ads. Google acts as an independent controller of this data under its own privacy policy. Learn more and manage your choices here:

• How Google uses information from apps that use its services: https://policies.google.com/technologies/partner-sites

App Tracking Transparency. On iOS, Gridlock asks for your permission before allowing tracking that uses your device advertising identifier. If you decline, you will still see ads, but they will be non-personalized. You can change this any time in Settings → Privacy & Security → Tracking.

Consent (EEA/UK). Where required, Gridlock presents a consent choice (via Google's User Messaging Platform) before personalized ads are shown.

Purchases. The optional "Remove Ads" purchase is processed entirely by Apple through the App Store. We never receive or store your payment card details. Apple handles this data under its own privacy policy.

Children

Gridlock is rated 4+ and is not directed at children under 13, and we do not knowingly collect personal information from children. Users below the applicable age of digital consent are shown non-personalized ads.

Your choices and rights

• Reset your advertising ID or limit ad tracking in your device Settings.
• Remove personalized ads by declining the tracking prompt or via your region's consent options.
• Depending on your location (e.g., under GDPR or CCPA/CPRA), you may have rights to access or delete personal data held about you. Because we do not collect personal data ourselves, such requests generally concern Google; use the Google links above, or contact us and we'll help direct you.

Data retention

Local data (scores, settings) remains on your device until you delete the app. Data processed by Google for advertising is retained according to Google's policies.
