This Privacy Policy explains how Numbra ("we", "us") handles information in connection with the mobile game Numbra (the "App"). We built Numbra to collect as little data as possible. We do not sell your data, we do not use advertising, and we do not use any analytics or tracking technologies.
Stored only on your device (never sent to us): your game progress, statistics, stars, achievements, settings, and any friend codes you add. This data lives in your device's local storage and is removed if you delete the App.
Sent to our leaderboard service when — and only when — you complete a Daily puzzle and have chosen to participate:
p_abc123…). It is not linked to your Apple ID, Google
account, email, phone number, or any real-world identity.
We do not collect your name, email, phone number, location, contacts, photos, health data, financial data, or any device advertising identifier.
Solely to operate the game's features:
Please note that your chosen display name and solve times are publicly visible to other players on the in-app leaderboards. Do not use a display name that reveals personal information you wish to keep private.
Leaderboard data is stored using Supabase, a hosted database provider that processes this data on our behalf. Data is transmitted over an encrypted HTTPS/TLS connection. The App itself is distributed via Apple and Google and built with Expo; these providers process data only as needed to deliver the App. We do not share your data with any other third parties, and we never sell it.
Leaderboard entries are retained to keep historical daily and weekly results meaningful. You can request deletion of your leaderboard data at any time by emailing us at contact.numbra@gmail.com and including your player code (shown on the Leaderboard → Friends screen). Deleting the App removes all locally-stored data from your device.
Numbra is not directed to children under the age of 13, and we do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will remove it.
Depending on where you live (for example, under the EU GDPR or California CCPA), you may have the right to access, correct, or delete the limited data described above. To exercise these rights, contact us at contact.numbra@gmail.com.
We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
