Asteroids Siege: Privacy Policy

Last updated: 26 October 2026

Asteroids Siege (app ID com.asteroidstd.game, formerly Asteroids Tower Defense Co-op) is a game by Big Oath Games. You can play it alone, or online with friends in co-op and siege. This page explains what happens to your information when you play.

The short version

• No accounts and no analytics.
• Ads only when you tap to watch one. They come from Google AdMob, which collects some device information, such as your advertising ID, whenever the game is online, unless you own Double Cores Forever (see Ads).
• One optional purchase, Double Cores Forever, paid through Google Play or the App Store. We never see your payment details.
• Your progress and settings are saved on your device.
• When you play online, the game sends the pilot name you typed and your moves in that game to our game server, which forgets them when the game ends.
• When you rate a game and tap SEND, a feedback report (your rating, your note, how that game went and some device details) goes to our feedback server, which keeps it for six months at most (see Feedback reports).
• Apart from these two, the game sends nothing to us.

What stays on your device

The game saves these on your phone or tablet. Apart from what a multiplayer game sends (see Playing online) and what a feedback report you send holds (see Feedback reports), they never leave it through the game:

• your campaign progress: the stars you've won on each level, and the star chart perks you bought with them;
• your cores (the game's currency for items) and how many of today's free cores you've collected;
• whether you own Double Cores Forever, as the store last told the game;
• your settings, such as sound, music and the pilot name you typed for multiplayer;
• feedback reports you've sent that haven't reached our server yet (at most 50), and the random install id that feedback reports carry (see Feedback reports);
• a short list of the game's own recent errors (the last 20), kept on the device for troubleshooting. It isn't sent anywhere.

If you've turned on your device's own backup (for example Android's backup to your Google account), your device may include this data in that backup. That backup is handled by your device and its provider under their privacy terms; we can't see it.

Playing online (co-op and siege)

Solo play works offline. When you create or join a multiplayer room, the game connects to our game server over an encrypted connection and sends:

• the pilot name you typed (up to 10 characters; it doesn't have to be your real name);
• the room code you create or enter;
• the star chart perks you've bought, so they apply to your ships in a co-op game;
• your moves during the game: which ships you build, where you post them, what you research and which items you use.

If you host a listed room (the default), players browsing open rooms see its line: your pilot name, co-op or siege, the level and difficulty or the map, and how many players are in it. A private room isn't listed: it's joined by its code only. An invite you share from a room is a link that holds only the room's code.

The other players in your room see your pilot name and your ships. The server keeps a room in memory only while it's being played and keeps nothing once the game ends: no names, no game records, no player accounts. Like any internet connection, the server needs your IP address to send the game back to you; the game server doesn't record it. Our hosting provider may keep standard connection logs for security and to keep the service running, as any web host does.

There's no chat. The only text other players see from you is your pilot name.

Feedback reports (optional)

After a level, in the pause menu and at the end of a multiplayer game, the game offers to send us feedback: how the game felt (too easy, just right, too hard or other) and a note. It's optional, and nothing is sent until you pick a rating and tap SEND. The report goes over an encrypted connection to our own feedback server, feedback.bigoathgames.com, which collects playtest feedback for Big Oath's games. A report holds:

• your rating and the note you typed, if any. We read every note, so please don't put personal details in it;
• what you were playing and how it went: the level, difficulty and mode (campaign, co-op or siege), the result, the wave you reached, how much hull your station had left, the play time, rocks destroyed, ships built and lost, your ore and crystal, the number of players, and your fleet (each ship class, its mark and how many you had);
• your campaign progress: your total stars, your stars on that level, and the star chart perks you've bought;
• the game's version and build, and when you made the report;
• your screen size and pixel density, and the user agent of the game's web view: a line of text naming the web view's version and, usually, your operating system and its version (on many Android phones it also names the phone model);
• a random install id, made the first time you send a report and kept on your device, so we can tell different players' reports apart, and a random id for each report, so a report that's sent twice is stored once.

A report doesn't hold your pilot name, your advertising ID, your purchases, your location or any account.

If you're offline, or the server is busy, the report waits on your device (up to 50 reports) and the game tries again when you start a level or send another report.

• The feedback server runs on Cloudflare, with its database in North America. Like any internet connection, it needs your IP address to answer, but it doesn't store the address: with each report it keeps only a salted hash of it (a scrambled code made with a secret key), so it can limit how many reports one network sends. The counters for that limit are deleted after a day. The feedback server keeps no request logs; Cloudflare, which hosts it, may keep standard connection logs for security, as any web host does.
• Only Big Oath Games reads the reports, on a password-protected page, to balance the levels and fix problems. We don't share or sell them, and we don't use them for ads.
• We delete reports once we've finished with them, and within six months of receiving them at the latest. A deleted report can remain in the database's restore history for up to 30 days, and then it's gone.

If your version of the game can't use the feedback server, SEND opens your own email app instead, with a draft to support@bigoathgames.com holding the same report as text (your rating and note, what you were playing and how it went, your progress, the game version and the device details above, but not the install id). Nothing is sent unless you send that email, and you can read and change it first. We receive it like any email, with your email address, use it to improve the game and to reply, and delete it on request.

Ads (Google AdMob)

The game shows only rewarded ads, and only when you choose to: you tap a button with a play sign to get a second chance after losing a level, to double the cores a win paid, or to collect free cores. No ad starts on its own, and the game works without ever watching one.

• The ads come from Google AdMob. When you're online, the game asks AdMob for an ad in the background so it's ready when you tap, so AdMob receives information even if you don't watch.
• To choose, show and measure ads and to prevent fraud, Google's AdMob software collects:
  • your device's advertising ID;
  • your IP address, from which a rough location is worked out;
  • device and app details, such as the phone model, operating system version and language;
  • how you interact with the ads, and crash and performance data from the ad software.
  Google handles this under the Google Privacy Policy; see also how Google uses information from apps that use its services.
• We don't receive this information. AdMob reports only totals to us, such as how many ads were shown.
• In the EEA, the UK and Switzerland, the game asks for your consent before personalised ads, using Google's consent form. You can change your choice any time: on the levels screen, tap "No ads" at the top ("Double Cores" once you own it), then "Ad privacy choices". Without consent the ads aren't personalised, though Google still uses some data, for example to limit how often an ad repeats and to prevent fraud.
• On iPhone and iPad, the game asks once whether ads may track you across apps (Apple's App Tracking Transparency). If you say no, the ads aren't personalised. You can change it in Settings > Privacy & Security > Tracking.
• Anywhere, you can reset or delete your advertising ID, or turn off personalised ads, in your device's settings (on most Android phones: Settings > Google > Ads, or Settings > Privacy > Ads).
• We ask Google to keep the ads to content suitable for a general audience with parental guidance.
• With Double Cores Forever you never need to watch an ad: its rewards come without one. Once the store has told the game that you own it, the game doesn't start the ad software at all: it asks AdMob for no ads and doesn't show the consent or tracking question. The ad software starts only if you tap "Ad privacy choices" (to show Google's form, still without asking for an ad), or if the purchase is refunded, after which the ads work as described above. Right after you buy it, the ad software that was already running stays on until you close the game.

Purchases (Google Play and the App Store)

Double Cores Forever is an optional one-time purchase. Google Play or the App Store handles the payment, so we never see your card or payment details. The game receives only the store's confirmation of what your account has bought, and keeps it on your device to switch the purchase on (and back off after a refund). The store keeps its record of the purchase under its own privacy policy. Refunds go through the store.

Permissions

• Internet, for multiplayer, ads and sending feedback reports.
• Advertising ID (Android), so AdMob can read the device's advertising ID (see Ads).
• Google Play billing (Android), for the optional purchase.
• Vibration, for small taps of haptic feedback. Nothing is collected through it.

Delete your data

Our game server keeps nothing after a game ends. The only things about you on our side are feedback reports you've sent and emails you've sent us. To delete them, and what's on your device:

• Your progress and settings (stars, perks, cores, pilot name): uninstall the game, or clear its storage in your device's settings (on Android: Settings > Apps > Asteroids Siege (Asteroids TD in older versions) > Storage > Clear storage). This also deletes feedback reports still waiting to be sent, and the install id (a new one is made if you send another report).
• Feedback reports you sent: ask at support@bigoathgames.com. There's no account to look you up by, so tell us roughly when you sent them and which level, or what a note said; we'll find them and delete every report from your install. Either way they're deleted within six months (see Feedback reports).
• Ad data is Google's, not ours: reset or delete your device's advertising ID in its settings (see Ads), and see the Google Privacy Policy for the rest.
• Your purchase is recorded by Google Play or the App Store with your account. Clearing the game's storage removes only the game's copy; "Restore purchase" in the game brings it back.
• Emails you sent us, beta sign-ups included: ask at support@bigoathgames.com and we'll delete them.

The beta

If you email us to join the beta, we use your email address only to invite you to the test on Google Play and to reply to you. We don't share it or add it to a mailing list, and we delete it on request.

Children

The game isn't directed at children under 13, and we don't knowingly collect personal information from children. The optional ads are limited to content suitable for a general audience with parental guidance.

Changes

If a future version changes any of this, we'll update this page and the date above before that version is released, and say what is collected and why.
