Privacy Policy

This is the short version. The full policy is below, but here is the gist:

Numbra (“we”, “us”, “our”) is a mobile game published under the name Numbra. You can reach us at support@playnumbra.com for any question related to this Privacy Policy.

We collect the following data, all of which is required to operate the game:

• Account data: email address, password (stored hashed), username, display name, and the country you select in your profile.
• Profile data: optional avatar image you upload, your in-game stats (matches played, wins, losses, win rate, streaks, ranked rating), and your last-active timestamp.
• Match data: the games you play, including the guesses you made, the digit length, the result (win or loss), and the number of turns. This data is associated with your account.
• Device data: standard app diagnostics from the Apple App Store, such as crash reports and aggregated usage. We do not collect advertising identifiers.

We collect this data on a “data minimisation” basis: we keep what we need to run the game and nothing more.

We do not collect your real name, your phone number, your contacts, your location, your photos beyond the avatar you choose to upload, your microphone audio, or your camera input. We do not use third-party analytics that track you across other apps or websites.

If a future feature ever needs any of this data (for example, a friend invite that uses your contacts), we will ask for explicit consent first and update this policy before collecting it.

We use your data to:

• Create and maintain your account.
• Run the game, including matching you with opponents, recording your results, and computing your stats and leaderboard position.
• Detect cheating, abuse, and bugs.
• Respond to your support requests.
• Send you essential service messages, such as password reset emails or policy change notices.

We do not use your data for advertising. We do not sell your data to third parties. We do not build advertising or marketing profiles about you.

We share your data only with the following service providers, all of which are bound by data protection agreements:

• Supabase — our database and authentication provider. Supabase stores your account data, profile, match data, and avatars on secure cloud servers. See supabase.com/privacy for their policy.
• Apple — when you download, install, or interact with the app through the App Store, Apple may collect diagnostic data under their own privacy policy. See apple.com/legal/privacy for details.

We do not share your data with advertisers, data brokers, or social media platforms.

Your public profile (username, display name, country, and avatar) and your ranked stats are visible to other players on the in-app leaderboards. Your email address and match history are never shown to other players.

You can delete your account at any time. Open Numbra, go to Profile, tap Account, then Delete account. The deletion is permanent and removes your email, profile, avatar, stats, and match history from our servers.

If you live in a region with data protection laws (such as the European Economic Area, the United Kingdom, California, or Brazil), you also have the right to request a copy of your data or to ask us to correct inaccurate data. Email support@playnumbra.com for these requests. We respond within 30 days.

If you are under 13, do not create an account.

The web landing page at playnumbra.com is a static marketing site. As of the date of this policy, it does not set cookies, does not use third-party trackers, and does not embed third-party analytics. We may revisit this in the future; if we do, we will update this section and ask for consent where required by law.

The Numbra app itself does not use web cookies. It stores the minimum data needed for your session (your authentication token and local preferences) using Apple’s standard secure storage.

Numbra is not directed to children under 13. We do not knowingly collect personal data from anyone under 13. If you believe a child under 13 has created an account, please contact us at support@playnumbra.com and we will delete the account as soon as possible.

For users between 13 and the age of digital consent in their country, a parent or guardian should review this policy with them before they sign up.

Numbra is a small team and we use cloud infrastructure that may process your data in regions other than the one you live in. Our database and authentication are hosted by Supabase on secure cloud servers. Where required by law (for example, for users in the EEA, UK, or Switzerland), we rely on standard contractual clauses or equivalent safeguards to protect your data when it is transferred internationally.

By creating an account, you understand that your data may be transferred to and processed in countries with different data protection rules than your home country.

We take reasonable steps to protect your data against unauthorised access, alteration, disclosure, or destruction. These steps include:

• Passwords are stored using a strong, salted one-way hash. We never see your password in plain text and we cannot recover it for you — only reset it.
• All traffic between your device and our servers is encrypted in transit using HTTPS / TLS.
• Access to production data is restricted to a small number of authorised team members and is logged.
• Backups are encrypted at rest. We aim to purge deleted-account data from backups within 90 days of deletion.

No system is perfectly secure. If we ever discover a data breach that affects your account, we will notify you by email at the address on file and, where required by law, notify the relevant authorities.

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page. If the changes are material, we will notify you through the app or by email before they take effect. By continuing to use Numbra after the changes take effect, you accept the updated policy.

For previous versions of this policy, email support@playnumbra.com and we will share them with you.
