?US — Privacy Policy

What we collect

• A random device ID generated on your phone at install. It is not your name, email, phone number, or account — just a random identifier so each phone can answer a question once.
• A push-notification token from Google Firebase Cloud Messaging, so we can deliver questions to your phone.
• Your answers — which option you tapped for each question.

What we do NOT collect

• No name, email address, phone number, or account.
• No location, contacts, photos, microphone, or other device data.
• No advertising identifiers. We do not track you across other apps or websites.

How we use it

• To send you questions as notifications and record one answer per device per question.
• To show aggregate results (how many chose each option). Results are anonymous counts.

Sharing

• We do not sell your data. We do not share it with advertisers.
• Push delivery uses Google Firebase Cloud Messaging; Google’s privacy policy applies to that transport.

Retention & deletion

Answers and the device ID are kept to show results. Uninstalling the app abandons your device token (it is automatically purged when it stops working). To request deletion of data associated with your device, email graggrobotics@gmail.com.

Children

?US is not directed to children under 13 and does not knowingly collect data from them.

Changes

We may update this policy; the “last updated” date will change. Continued use means acceptance.
