Who we are

Bellwarden is made by Sni Gaming, an independent developer in Norway. If you have a question about this policy or your data, write to henrikmoepe@gmail.com.

The short version

The game has no accounts, and we run no servers. Your progress lives on your phone. We never see your name, email or location. The only data that leaves your phone goes to Google, for ads, and to Google or Apple, for purchases and for the phone's own backup. Advertising is the one place where data is used to track you across other apps and websites, and on iPhone and iPad that happens only if you allow it.

What stays on your phone

• Your save. Progress, settings and the record of what you have bought are stored on your device.
• Notifications. If you turn them on, reminders (chest full, research done and so on) are scheduled by the phone itself. Nothing is sent anywhere to make them work.

Backup by your phone

Android: Android can back up the save to your Google account, so your progress comes back on a new phone or after reinstalling. This is Android's Auto Backup, run by Google under Google's Privacy Policy. You can switch it off in your phone's backup settings.

iPhone and iPad: Apple's device and iCloud backups may include the game's save, like the data of any other app. This is run by Apple under Apple's Privacy Policy, and you can switch it off in your iPhone's iCloud settings.

We cannot read these backups.

Ads

The game shows ads only when you choose to watch one for a reward. Ads come from Google AdMob. To show ads, measure them and stop fraud, Google's software in the game may collect:

• your device's advertising ID,
• your IP address and the rough location it suggests,
• information about your device (model, operating system, language),
• how you interact with the ads.

If you are in the European Economic Area, the United Kingdom or Switzerland, the game asks for your consent before personalised ads are shown. You can change your answer at any time in Settings → Ad privacy. You can also reset or delete your advertising ID in your phone's settings.

How Google uses this data: How Google uses information from sites or apps that use its services.

Tracking (iPhone and iPad)

Google uses the advertising ID and the data above to choose and measure ads, and this can link data from this game with data from other apps and websites. Apple calls this tracking. On iPhone and iPad the game therefore asks your permission before any tracking happens, with Apple's own prompt, "Allow Bellwarden to track your activity across other companies' apps and websites?"

• If you choose Ask App Not to Track, the game cannot read your advertising ID and ads are not personalised to you. You can still watch ads for rewards, and the game works the same.
• You can change your choice at any time in your iPhone's Settings → Privacy & Security → Tracking.

The data types that Google's ad software in the game may collect, and that we have declared to Apple, are: advertising ID (device ID), rough location from the IP address, ad interactions and ad impressions (usage data), and crash and performance data. They are used for third-party advertising, advertising measurement, analytics, and keeping the app working and secure. We do not receive this data ourselves and we do not sell it.

Purchases

On Android, purchases are handled by Google Play. On iPhone and iPad, they are handled by the Apple App Store. We never see your card or payment details. The game receives a purchase confirmation from the store and keeps it on your phone, so an item is not lost or given twice. Restore Purchases, at the bottom of the Store's Offers tab, asks the store again for what you have bought. Google's handling of payments is described in the Google Payments Privacy Notice, and Apple's in Apple's Privacy Policy.

Children

Bellwarden is not made for children under 13, and we do not knowingly collect data from them.

Your rights

Under the GDPR you have the right to access, correct and delete your personal data, and to object to its use. We do not hold any data about you ourselves. For data collected by Google, use your Google account's privacy settings, or write to us and we will help. For data held by Apple, see Apple's Data and Privacy page. To erase your game progress, use Settings → Erase all progress, or uninstall the game. If you think your data has been handled wrongly, you can complain to the Norwegian Data Protection Authority, Datatilsynet.

Changes

If this policy changes, the new version will be posted on this page with a new date.
