Daily Puzzle Competition
Privacy Policy
Stealth Launch, LLC operates Daily Puzzle Competition. This policy explains what the app stores, what our score server receives, which outside services are involved, and the choices you have.
Summary
- No account, email, phone number, or social login. You never give us your name.
- The app creates a random install ID. Our server keeps it with your games so it can run one attempt per puzzle per day and fair leaderboards.
- A nickname is optional. You choose one only when you want to post a score. Leaderboards show the nickname and the score, never the install ID.
- One full-screen ad from Google AdMob may appear after a game, requested as non-personalized and rated G. Daily Puzzle Competition Plus members see no ads.
- Daily Puzzle Competition Plus is an optional subscription sold and billed by Apple or Google. We never see your payment details, and our server stores nothing about purchases.
- No analytics SDK, no crash-reporting SDK, and no tracking prompt. We do not sell personal information.
Information stored on your phone
The app keeps these on the device, in the app’s own storage:
- A random install ID, created the first time the app opens
- Your nickname, if you set one
- Settings: sound, music, haptics, and the language you chose
- Moves for a puzzle in progress, so you can close the app and carry on
- A local history of the days you played (for streaks and the Archive calendar), cached leaderboards, and which games have already shown their ad today
- Whether Daily Puzzle Competition Plus is active, as last reported by the store
Uninstalling the app or clearing its data removes all of this from the phone.
Information our score server receives
The app talks to our own server at dpc.stealthlaunched.com. It stores:
- Install ID, and your nickname if you post a score
- For each puzzle you start: the game, the UTC day, whether it was played from the Archive, start and finish times, the time measured by the server, the status (in progress, solved, or given up), what you submitted to check the solve (your moves or finished grid), move counts, wrong submissions, level times where a game has levels, whether the score was posted, and a signature that protects the result
- A timestamp for each request, kept for about one hour, to limit how often one install can call the server
Our server does not ask for or store your name, email address, phone number, contacts, location, advertising identifier, or anything about purchases. Like any internet service, the hosting network sees your IP address in order to deliver responses; the score database does not store it.
We use this information only to serve the daily puzzles, check solves, rank leaderboards, show your history, enforce one attempt per puzzle per day, and keep the boards fair (for example, removing a score or blocking an install that abuses the boards).
Leaderboards and nicknames
Posted scores appear on public daily and monthly leaderboards with your nickname, rank, and score. Anyone using the app can see them. Nicknames are 3–16 characters; a block list rejects slurs and anything that looks like a link. Don’t use your real name if you don’t want it shown. Archive plays are never ranked or posted.
Advertising (Google AdMob)
Without Daily Puzzle Competition Plus, the app may show one full-screen ad when you leave a game’s results screen, whether you solved the puzzle or gave up. You give up with the Give up button or by leaving a game in progress with Back; the app asks first, then shows the solution and opens the results marked DNF (did not finish). The ad appears at most once per puzzle per day, even if you open those results again. Closing or switching away from the app does not give up a game and does not show an ad. Ads are provided by Google AdMob, part of Google LLC, through the Google Mobile Ads SDK. We request non-personalized ads only and limit ad content to a G rating. We do not send your nickname, install ID, or scores to Google.
Even for non-personalized ads, Google may collect or receive information such as your IP address, device and app information, ad interactions, diagnostics, and, where the operating system makes it available, the device advertising identifier. The app does not ask for Apple’s tracking permission, so on iPhone it does not get access to the advertising identifier (IDFA). On Android you can reset or delete your advertising ID in the device’s Google settings. Google’s processing is described in its own policy: How Google uses information from sites or apps that use its services.
Daily Puzzle Competition Plus (subscriptions)
Daily Puzzle Competition Plus is an optional auto-renewing subscription, monthly or yearly. It lets you play past days from the Archive (Archive plays are never ranked) and removes the post-game ad. It is sold and billed by Apple (App Store) or Google (Google Play) through their own in-app purchase systems, which the app uses directly. There is no third-party subscription service. Apple or Google handle your payment details under their own privacy policies; we never receive a card number. The app asks the store whether your subscription is active and remembers the answer on the phone. Our server receives and stores nothing about purchases. We may receive aggregated, non-identifying sales reports from Apple and Google.
Analytics and crash reporting
Daily Puzzle Competition contains no analytics SDK and no crash-reporting SDK. If you share crash reports or diagnostics with developers through your phone’s own settings, Apple or Google may pass those to us under their terms.
Third parties
We do not sell or rent personal information. Information is processed by:
- Apple and Google: app distribution, in-app purchases, and subscription billing
- Google AdMob: the post-game ad for players without Daily Puzzle Competition Plus
- The hosting provider that runs our score server, which processes data only to run it for us
We may disclose information if required by law or to protect the safety of players and the integrity of the service.
Data retention
- Scores and attempts are kept so past daily and monthly leaderboards and your Archive history stay available, until you ask us to delete them.
- Rate-limit timestamps are deleted after about one hour.
- Data on your phone stays until you uninstall the app or clear its data.
- Emails you send us are kept as long as needed to answer and keep a record of the request.
Delete your data
Email contact@stealthlaunch.com with your nickname, and your install ID if you have it. We will delete your nickname and all of your scores and attempts from our leaderboard server, and reply within 30 days. If several players share the nickname, we may ask for more details (such as the days and games you played) to find the right record.
Apple and Google keep their own records of Daily Puzzle Competition Plus purchases; those are managed by Apple and Google under their own privacy policies. Uninstalling the app removes only what was stored on that phone, not scores already on the server. After a reinstall the app has a new install ID, so tell us about the old nickname too.
Children’s privacy
Daily Puzzle Competition is a general-audience puzzle game and is not directed at children under 13. It needs no account and collects no name, email, or contact details. Ads are non-personalized and limited to a G rating. We do not knowingly collect personal information from children under 13 beyond the install ID and gameplay data described above. If you are a parent or guardian and believe your child posted a nickname or scores, email contact@stealthlaunch.com and we will delete them.
International users
Stealth Launch, LLC is based in Puerto Rico, United States. Our score server and the services named above may process information in the United States and other countries whose data protection laws may differ from yours. Depending on where you live (for example in the EU, UK, or California), you may have rights to access, correct, delete, or object to the processing of your information. To exercise them, email contact@stealthlaunch.com. We rely on performing the service you ask for (running the game and leaderboards) and our legitimate interest in keeping the boards fair and the free version supported by ads.
Security
The app talks to our server over HTTPS. Results are signed so they can’t be altered, and the install ID is never shown publicly. No method of storage or transmission is completely secure, but we limit what we collect to what the game needs.
Changes
We will update this policy if the app’s data practices change, and change the effective date above when we do.
