Privacy Policy

Overview

Blockfill is a block puzzle game developed by SupafastTech LLC. This policy explains, in plain language, what information the app collects, why we collect it, and who it is shared with. Signing in is entirely optional: you can play the whole game as a guest without providing anything.

Data We Collect

Depending on how you use the app, Blockfill collects the following:

• Advertising identifier - the app shows occasional interstitial ads through Unity Ads (Unity Technologies). To display and measure these ads, Unity's SDK reads your device's advertising identifier (Android Advertising ID, or Apple's IDFA through SKAdNetwork on iOS).
• Email address and account ID - if you choose to sign in with Apple or Google, we create an account on our own server and store your email address and a unique account ID there. Signing in is optional and only needed if you want your progress synced across devices and shown on the leaderboard.
• Game scores - if you are signed in, your best scores are sent to our server so they can sync across devices and appear on the leaderboard. If you play as a guest, scores never leave your device.
• Approximate location - when you set a new best score, the app looks up an approximate country and city from your IP address using a third-party lookup service (ipwho.is). We never access your device's precise GPS location.
• Device information - your device model and the app version. This travels together with the data above and helps us debug issues and keep the leaderboard fair.

Signing In (Optional)

You do not need an account to play Blockfill. Signing in with Apple or Google is entirely optional and only unlocks synced progress and the online leaderboard. If you skip sign-in, the game works exactly the same in guest mode and nothing described in this policy about accounts, scores, or location applies to you.

Advertising

Blockfill shows interstitial ads served through Unity Ads, a service operated by Unity Technologies. Unity's SDK collects your device's advertising identifier to serve and measure ads. We do not run any other ad network, and we do not use Google AdMob or Firebase. You can reset or limit your advertising identifier, or opt out of personalized ads, at any time from your device's system settings.

Data Sharing

We do not sell your data. It is shared only with the following parties, for the purposes described above:

• Unity Technologies (Unity Ads) - receives your advertising identifier to show and measure ads.
• Our own server (api.blockfill.supafast.tech) - stores your email, account ID, synced scores, approximate location, and device information for signed-in accounts.
• ipwho.is - receives your IP address to resolve it into an approximate country and city when you set a new record.
• Our internal team Telegram channel - when you sign in, set a record, or use certain other features, your account information, approximate location, device information, and score are also forwarded to a private Telegram channel used internally by our team to monitor activity and troubleshoot issues. This is an internal operational log, not a public or advertising channel.

What We Do Not Collect

Blockfill does not access or collect your precise location, contacts, photos, files, microphone, camera, health data, payment information, messages, calendar, or the list of apps installed on your device. The app has no crash reporting, analytics, or tracking SDKs beyond the advertising SDK described above.

Stored Locally on Your Device

Your app settings (sound, vibration, and animation toggles), the state of your current game, and session tokens used to keep you signed in are stored only on your device. They are removed automatically when you uninstall the app.

Data Retention and Deletion

Data linked to your account (email, account ID, and synced scores) is kept on our server for as long as your account exists. You can request deletion of your account and all associated server-side data at any time - see https://supafast.tech/en/blockfill/delete-account for instructions. Local data on your device is removed by uninstalling the app.

Children's Privacy

Blockfill is suitable for general audiences and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal data through the app, contact us and we will delete it.

Security

Data sent to our server is transmitted over HTTPS/TLS encryption. We take reasonable steps to protect the information we store, but no method of transmission or storage is completely secure.

Changes to This Policy

We may update this Privacy Policy as the app changes. The current version is always available at this address, and the date below reflects the most recent update.
