SumBlitz: Mental Math Game ·
Codebot Technology
Effective date: October 14, 2026
This Privacy Policy explains how Codebot Technology ("we", "us", "our") handles information in connection with the SumBlitz mobile application for Android (the "App"). By using the App you agree to the practices described here.
The App has no accounts and no sign-in. Your profile, scores, progress and settings are stored on your device.
We use Google Firebase (Analytics, Crashlytics and Remote Config) to understand how the App is used, fix crashes and adjust features. This data is linked to app-instance and device identifiers, not to your name or email.
The App shows ads through Google AdMob, which may also serve ads from Meta Audience Network. These ad networks may collect your device's advertising ID and related data.
We advertise the App on Meta platforms (Facebook and Instagram), and the App may share install and usage events with Meta to measure those campaigns.
Purchases are processed by Google Play. We never see your payment details.
We do not sell your personal information for money.
The App saves the following information locally on your device so the game works:
Your display name (a random name such as "Mathlete 1234" unless you change it) and your chosen avatar cosmetics.
Game data: rounds played, answers, mistakes, scores, personal bests, XP, level, streaks, league standings, achievements, coins and unlocked items.
Friend challenges you have sent or received.
Settings and preferences (sound, notification and reminder choices, onboarding status).
Whether you have purchased "Remove Ads".
This data is not uploaded to us as a profile. Some usage events about it (for example "round completed" or "achievement unlocked") are sent to Firebase Analytics, as described in Section 2.
If you have turned on Android's backup feature, Android may include this data in your device backup, which is stored in your Google account under Google's Privacy Policy (https://policies.google.com/privacy). We cannot access these backups.
The App uses the following third-party services. Each one collects and processes data under its own privacy policy.
We use Firebase Analytics, including its real-time reports, to understand how players use the App. It collects:
App interactions and in-game events, such as screens viewed, rounds played, modes chosen, purchases started and ads watched.
An app-instance ID and, where allowed, your device's advertising ID.
Device and app information, such as device model, operating system version, language, country and app version.
Approximate location derived from your IP address (Firebase does not store the IP address itself).
We use this information to improve the App, understand which features are popular and measure our marketing. Analytics data is kept for up to 14 months. Learn more at https://firebase.google.com/support/privacy and https://policies.google.com/technologies/partner-sites.
If the App crashes or runs into an error, Crashlytics collects a crash report. The report includes the stack trace, device model, operating system version, app version, memory and disk state at the time of the crash, and a Crashlytics installation ID. We use it only to find and fix bugs. Crash reports are kept for up to 90 days.
Remote Config lets us change App settings and features (for example how often reminders appear or ad frequency) without releasing an update. To deliver these settings, it uses a Firebase installation ID and basic device and app information, such as app version, language and country.
The App shows rewarded ads (which you choose to watch for in-game rewards) and interstitial ads through Google AdMob. AdMob uses mediation, which means ads may be served by Google or by other ad networks, including Meta Audience Network (Meta Platforms, Inc. / Meta Platforms Ireland Ltd.). These ad networks may collect:
Your device's advertising ID (Android Advertising ID).
Your IP address, which can be used to estimate your general (approximate) location.
Device and app information, such as device model, operating system version, language and app version.
Interactions with ads, and diagnostic and performance data.
They use this data to deliver, measure and, where allowed, personalize ads, and to prevent fraud and abuse. Where required by law (for example in the European Economic Area, the United Kingdom and Switzerland), the App asks for your consent before personalized ads are shown, and your choice is passed to the ad networks.
Google: https://policies.google.com/technologies/partner-sites and https://support.google.com/admob/answer/6128543
Meta: https://www.facebook.com/privacy/policy and https://www.facebook.com/ads/audience_network/
If you buy "Remove Ads", the App stops showing ads, and bonuses that would otherwise require a rewarded ad are granted without one.
We promote the App through ad campaigns on Meta platforms such as Facebook and Instagram. To measure how well these campaigns work, the App uses the Meta (Facebook) SDK, which sends Meta:
App events, such as app installs, app opens, completed onboarding and purchases.
Your device's advertising ID, device and app information, and IP address.
Meta uses this information to attribute installs to our ads, measure campaign performance and help show our ads to people likely to be interested. If you are logged in to a Meta account on your device, Meta may link this information to that account under its own Data Policy. We do not receive your Meta account details. You can control how Meta uses this data in your Meta account's Ad Preferences (https://www.facebook.com/adpreferences) and "Your activity off Meta technologies" settings.
In-app purchases are processed entirely by Google Play. Google collects your payment information under the Google Payments Privacy Notice (https://payments.google.com/payments/apis-secure/get_legal_document?ldo=0&ldt=privacynotice). The App receives only the purchase status and a purchase token from Google Play so it can unlock what you bought. We do not receive your name, email address or card details.
If you choose to rate the App, the rating is submitted through Google Play's review system and governed by Google's policies. We do not receive your Google account details.
When you challenge a friend, the App creates a link that contains your display name, your score and time, the round settings and a random challenge ID. The link is built on your device and shared only when you send it, through the app you choose (for example a messaging app). Anyone who receives the link can see this information. Do not use your real name as your display name if you do not want it shared.
Challenge links point to a web page at sumblitz.github.io, hosted by GitHub. The page opens the challenge in the App or sends you to Google Play. As with any website, GitHub may log technical data such as your IP address when the page loads. See the GitHub Privacy Statement (https://docs.github.com/en/site-policy/privacy-policies/github-general-privacy-statement).
If you send feedback from the App, it opens your email app with a pre-filled message that includes the App version, your device manufacturer and model, and your Android version. Nothing is sent until you press send. If you email us, we receive your email address, your message and those device details. We use them only to respond to you, fix problems and improve the App.
The App asks Android for the following permissions, and uses each one only for the purpose described here.
Notifications (android.permission.POST_NOTIFICATIONS): lets the App send the daily math quiz, practice reminders and streak reminders. On Android 13 and later, the App asks you before sending any notifications, and you can say no. You can turn them off at any time in the App's Settings or in Android Settings → Apps → SumBlitz → Notifications.
Run at startup (android.permission.RECEIVE_BOOT_COMPLETED): Android clears scheduled reminders when your device restarts. This permission lets the App set your reminders and refresh its home-screen widget again after a restart. It does not make the App run all the time, and it gives the App no access to your data.
Full-screen notifications (android.permission.USE_FULL_SCREEN_INTENT): lets the App show the optional math quiz card on your lock screen. When you tap the card to open the App, Android asks you to unlock your device with your own screen lock. The App never sees your PIN, pattern, password or biometrics. You can turn the lock-screen quiz off in the App's Settings. On Android 14 and later, you can also turn off this permission in Android Settings.
The App does not request access to your contacts, camera, microphone, photos, precise location or files.
We use information only to:
Provide the App's features and save your progress on your device.
Understand how the App is used and improve its features, difficulty and content.
Detect, diagnose and fix crashes and bugs.
Adjust App settings remotely and test changes.
Show ads, including rewarded ads you choose to watch, and unlock purchases.
Measure and improve our advertising campaigns on Meta and other platforms.
Respond to your messages.
Prevent fraud and abuse, and comply with legal obligations.
We do not sell your personal information for money. Information is shared only:
With Google (Firebase, AdMob, Google Play) and Meta (Audience Network and the Meta SDK), as described in Section 2. Some of this sharing for ads and campaign measurement may count as "sharing" for cross-context behavioral advertising, or a "sale", under some US state laws. You can opt out as described in Section 8.
With the people you choose to send challenge links to.
When required by law, or to protect our rights, users or the public.
As part of a merger, acquisition or sale of assets, under the protections of this policy.
On-device data stays on your device until you delete it. To delete all of it, uninstall the App or go to Android Settings → Apps → SumBlitz → Storage → Clear data.
Analytics data (Firebase Analytics) is kept for up to 14 months and then deleted automatically.
Crash reports (Crashlytics) are kept for up to 90 days.
Emails you send us are kept only as long as needed to handle your request, and no longer than 24 months.
Data held by Google and Meta for advertising is retained under their policies. You can manage it at https://myaccount.google.com/ and https://accountscenter.facebook.com/.
The App has no user accounts, so there is no account to delete. To ask us to delete analytics or crash data linked to your device, email us from the App (Settings → Feedback) so we can identify your app instance, and we will delete it within 30 days.
Ad consent: If you are in the EEA, UK or Switzerland, the App asks for your consent to personalized ads and related data processing. You can change your choice at any time in the App's Settings.
Advertising ID: You can reset your advertising ID or delete it in Android Settings → Privacy → Ads (or Settings → Google → Ads). When the advertising ID is deleted, ad networks and Meta can no longer use it to personalize ads or measure campaigns.
Meta: You can manage how Meta uses information from apps at https://www.facebook.com/adpreferences and in "Your activity off Meta technologies" in your Meta account.
Remove Ads: Buying "Remove Ads" stops ads in the App.
Notifications: You can turn off reminders and quizzes in the App's Settings or in Android settings.
Privacy rights: Depending on where you live (for example under the EU/UK GDPR, or California's CCPA/CPRA and similar US state laws), you may have the right to access, correct or delete your personal information, to restrict or object to its processing, to data portability, to opt out of targeted advertising or the "sale" or "sharing" of personal information, and to withdraw consent. To use these rights, contact us at the address below. We will not discriminate against you for using them. You may also complain to your local data protection authority.
Where the GDPR applies, we rely on:
Your consent for personalized advertising and for sharing data with Meta for campaign measurement.
Performance of our agreement with you to provide the App and purchases.
Our legitimate interests in analytics that help us improve the App, crash reporting, remote configuration, answering messages, keeping the App secure and showing non-personalized ads.
Game data stays in the App's private storage, which other apps cannot read. Data sent to Firebase, ad networks and Meta is encrypted in transit. No method of storage or transmission is completely secure, but we work to protect your information.
The App is intended for a general audience and is not directed at children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, contact us and we will delete it.
Google, Meta and GitHub may process information in the United States and other countries whose data protection laws may differ from yours. These providers use legal safeguards such as the EU-US Data Privacy Framework and Standard Contractual Clauses.
We may update this Privacy Policy from time to time. We will post the new version on this page and change the effective date above. If a change is significant, we will also let you know in the App or in the Google Play listing.
