Privacy Policy

The short version

Your game progress lives on your phone. Two things leave your device: advertising data — collected by Google AdMob so it can show and measure ads, and by TikTok so we can tell which of our TikTok ads actually led to installs; and — only if you choose a callsign — your callsign and Endless scores, sent to our leaderboard so other players can see where you rank. None of the advertising collection starts until you agree to it, and buying Blockstellar Deluxe removes the ads and with them that collection. Declining the callsign keeps the leaderboard off.

There is no login, no password, and no email address anywhere in the game.

The rest of this page explains that in detail. It describes the app only; this website itself sets no cookies and runs no analytics.

Game progress

Your unlocked levels, block skins, coins, rank, daily streak, achievements and settings are written to your device's local storage by the app. They are not transmitted anywhere, not backed up to us, and not readable by us. There is no account system and no login.

Uninstalling Blockstellar deletes all of it permanently. Because we never hold a copy, we cannot restore progress that is lost this way. Your leaderboard entry is the one exception, and it is covered next.

Leaderboard

Blockstellar has a global leaderboard with daily, weekly and all-time boards. It is optional. The game asks you to choose a callsign when you first open it; if you decline, the app never contacts our leaderboard server at all, and nothing in this section applies to you.

If you do choose one, we store the following on our own server:

• Your callsign — the name you type (3–14 letters, numbers and underscores; the game also offers generated suggestions like "NovaPilot"). It is shown to other players on the leaderboard, so please do not use your real name or anything else you would not want other players to see. You can change it in Settings, and names that break our rules are refused or removed.
• A random identifier created on your device the first time you play. It is not derived from your phone, your Google account, or your advertising ID, and we cannot connect it to you as a person.
• Your Endless scores — your best score and the number of lines cleared in a run.

That is the entire list. No email address, no phone number, no contacts, no location, no advertising ID. We do not sell this data, do not share it with anyone, and never use it for advertising.

Our leaderboard server also sees your IP address when your device submits a score, which it uses to limit how often one device can post. It is used for that check and is not stored alongside your scores.

Past daily and weekly boards are kept as history, and your all-time entry is kept, until you ask us to remove it — see below.

Removing your entry. Open Settings in the game and tap Remove me from the leaderboard. Your callsign and scores are deleted from our server straight away — there is no waiting period and you do not need to ask us. Your progress on the device is untouched, and you are free to pick a new callsign later if you change your mind.

If you have already uninstalled the game, email us the exact callsign you used and we will remove it. Because the identifier is random and not linked to you, the callsign is the only way we can find your row.

Reporting a callsign. Every leaderboard row has a flag button. Use it on any name that is offensive, impersonating someone, or spam, and we will review it.

Rival alerts (notifications)

If you turn on Rival alerts (the game offers it once after a ranked run, and it lives in Settings), the game registers your device for push notifications through Google's Firebase Cloud Messaging and we store the resulting notification token, your timezone offset and your device language on our server, alongside your player identifier. They are used for exactly one thing: telling you when another player passes you on the leaderboard — at most once or twice a day, never while you are playing, and not during the night in your timezone. Switching Rival alerts off in Settings deletes the token from our server; removing yourself from the leaderboard deletes it too. Google delivers the notification under its own privacy policy. Declining the notification permission keeps everything in this section off.

Advertising

The free version of Blockstellar shows advertising supplied by Google AdMob. There are two kinds:

• Rewarded ads you choose to watch in exchange for something in the game — a revive, doubled coins, extra pieces. These never start on their own.
• Occasional full-screen ads between runs. These are not shown during a game, when the app opens, or in your first few sessions.

Your consent choice

Where the law requires it — in the UK and the European Economic Area — the game asks for your consent before any advertising data is collected, using Google's certified consent platform. The prompt appears the first time you open the game. Until you answer it, no advertising data is gathered or sent, by Google or by TikTok. If you decline, none is gathered at all.

You can revisit the choice at any time from Settings › Privacy options inside the game, where that entry point is required.

Who receives it

Google acts as an independent controller of the data it collects through these ads. Its handling is governed by the Google Privacy Policy and described further under how Google uses information from partner sites and apps.

Measuring our TikTok ads

We advertise Blockstellar on TikTok. So that we can tell which of those ads actually lead to installs, rather than paying for guesses, the app includes the TikTok App Events SDK. It reports when the app is installed, opened, and opened again on a later day.

What it sends:

• Your advertising ID — the same resettable Android identifier described above, so TikTok can connect an install to an ad you were shown.
• Install, launch and return events — that the app was installed, opened, or opened again later. Not what you do inside it: no scores, no purchases, no callsign, no leaderboard data.
• Basic device and app details — device model, Android version, app version and language.

If you are in a US state with a privacy law, the game offers a Don’t sell or share my data choice under Settings › Privacy options. When a US state privacy signal is present on your device, the app puts the TikTok SDK into limited data use mode, which restricts how TikTok may process what it receives. Install measurement itself continues; what changes is what TikTok is permitted to do with it afterwards. The setting is read when the game starts, so a change takes effect the next time you open it.

TikTok acts as an independent controller of what it receives, under the TikTok Privacy Policy. We never send it your callsign, your scores, or any account identifier — the game has no accounts, and nothing you could type is ever passed to it.

What is collected, and by whom

The table below is everything that leaves your device, who receives it, and why. It matches the Data safety declaration on our Google Play listing.

None of it is sold. Data in transit is encrypted. The advertising rows are handled by Google and TikTok as independent controllers, and none of them are collected unless you have agreed to advertising data collection; the leaderboard rows are held by us and shared with no one, though your callsign and score are shown to other players by design.

Purchases

Blockstellar Deluxe is a one-time in-app purchase handled entirely by Google Play. We never receive, see, or store your payment details — Google confirms only that a purchase exists for your account, which is how the upgrade restores itself if you reinstall or change device.

Your controls

• Reset or delete your advertising ID — Settings › Google › Ads on Android. This breaks the link between your device and previously collected ad data.
• Opt out of ad personalisation — in the same Android settings screen. You will still see ads, but they will not be personalised.
• Opt out of sharing (US states) — Settings › Privacy options in the game. Residents of US states with privacy laws can choose Don’t sell or share my data. See the note below on what that does.
• Withdraw your consent — Settings › Privacy options in the game, where that entry point is required. Withdrawing stops the advertising collection, TikTok included, from the next time you open the game.
• Remove advertising entirely — buy Blockstellar Deluxe.
• Stay off the leaderboard — decline the callsign prompt when the game first opens, or simply never set one in Settings. Nothing is sent to our server unless you have a callsign.
• Delete your leaderboard entry — Settings › Remove me from the leaderboard, in the game; it is immediate. Or email us with the callsign you used and we will remove it and its scores. Full steps: Delete your data.
• Delete everything else — uninstall the app. All local progress goes with it, and because we hold no copy of it we cannot restore it.

Depending on where you live you may have rights to access, correct, or delete personal data held about you. The data we hold is your leaderboard entry — your callsign, the random identifier, and your scores — and a deletion request is satisfied instantly in-app: Settings › Remove me from the leaderboard. If you no longer have the game installed, email support-blockstellar@yallamigo.com with your exact callsign and we will remove it. Requests about the advertising data described above are a matter for Google and TikTok, starting with the Android ad settings listed higher in this section — but write to us anyway if you are unsure and we will point you the right way.

Children

Blockstellar is intended for players aged 13 and over and is not directed at children. We do not knowingly collect data from children under 13. If you believe a child has provided data through this app, contact us and we will help you resolve it with Google.

Changes to this policy

If a future update changes what is collected, we will update this page and the Google Play Data safety declaration before that update is released, and move the effective date at the top. Material changes will also be noted in the Play listing's release notes.
