MonstersDuko privacy policy

Last updated 23 October 2026

MonstersDuko is a puzzle game by AltitudeDevLabs. It has no sign-up and never asks for your name, email, contacts, location or photos. This page explains the little it does send, and how to delete it.

What the game sends to our server

For leaderboards and the shared "how others did" numbers, the game talks to our own server (the hunt server). It sends:

• A random player ID and a secret code, made up on your phone the first time you play. They identify your copy of the game, not you.
• Your hunter name. The game picks a random one, such as "Hollow Warden 417"; you can change it in Settings. It is shown on the leaderboards, so don't use your real name unless you want to.
• How each level went: the level number, whether you won, the seconds left on the clock, how many power-ups you used, whether it was your first try, and when. The same for floor battles and your best boss run.
• Your first minutes: when you start the guided first board, when its guide ends, and when you first win it. This tells us whether new players get stuck at the start.
• Your lodge, if you join one: which lodge you are in, the ready-made phrases you send there, the lives and supplies you ask for or give, and, if you found a lodge, the name you give it. A lodge has no free typing: nobody can write you a message.
• Playing with and against others: your duels (whom you challenged, your times on each board, and the monsters you placed as you played, so a duel can be watched and replayed), your weekly League boards and scores, your Endless run and Nightmare scores, and your medals.
• Boards you make in the Workshop: the board itself (its rooms and its answer) when you share it, and for boards you play, whether you solved them, how fast, and whether you liked them. A board carries no text of yours, only your hunter name as its maker.
• The monster you wear as your picture, the version of the game you run, and when you last played.

Other players see your hunter name, your picture and your scores on the leaderboards, and can open your hunter profile: your name, a six-character hunter ID that others can find you by, the level you have reached, your points, medals and duel record. Your duels can be watched by other players, a little behind the play, and replayed for two weeks afterwards. The hunters in your lodge also see what you send and ask for there, and news of the lairs you beat. You can block a hunter, so that their challenges and invitations no longer reach you, and report a hunter, a lodge or a shared board to us; a report says who sent it and the reason picked, and only we read it. The per-level numbers are only ever shown combined, and only once at least 20 players have tried that level. The public leaderboards (hunter names, pictures and scores, and lodge names and points) are also shown on our website, altitudedevlabs.com. The day's top three hunters and each week's League champions are also named, with their pictures and scores, in posts on our Facebook page.

The game also asks the server for the house ads (promotions for our own game, no ad network) and, in the version shared outside Google Play, whether a newer version exists. Those requests carry nothing about you. Now and then the game also sends how many times each house ad was shown and tapped that day; those counts carry no player ID or name, and are only added up.

If you use Move to a new phone in Settings, a copy of your progress (levels, settings, hunter name and ID) waits on the server under a short code. It is deleted as soon as the new phone collects it, or after 24 hours, whichever comes first.

If the game crashes, the next time it starts it sends our server a crash report: the game version, the Android version, the phone model and the technical details of the error. It carries no player ID or name, so it can't be tied to you. We use it only to fix the bug.

What else the server sees

Like any website, the server sees the internet (IP) address a request comes from. It is used, in memory only, to stop anyone flooding the server, and it appears in ordinary web server logs, which are deleted automatically within about two weeks. It is not stored with your player data and is never used to find out who or where you are.

What stays on your phone

Your progress, settings, lives and streak are stored on your phone. If Android backup is on, Android may include them in your own Google account backup; we never see that copy. Reminders, if you turn them on, are scheduled on the phone. While they are on, the phone also asks our server now and then, with your player ID, whether something is waiting for you (a duel turn, a request in your lodge, the League's results), so it can tell you. Nothing else is sent.

Purchases

If you buy "Remove ads" or a supply pack, Google Play handles the payment. The game on your phone is told that the purchase went through; our server is not, and we never see your card or account details.

What we don't do

• No advertising ID, device ID or tracking across other apps.
• No selling or sharing of your data with anyone.
• No analytics, crash-reporting or advertising companies inside the game. (Google Play itself may show us anonymous crash counts, as it does for every app it installs.)

Deleting your data

In the game, open Settings → Delete my online data. That removes your hunter name and everything listed above from the server straight away: your results and scores, boss runs and floor battles, duels, League, Endless and Nightmare records, medals, the boards you made, your place and words in a lodge, your reports, first-minutes steps and any waiting transfer code. They also leave the leaderboards and shared numbers. Your progress on the phone is kept. Uninstalling the game deletes everything on the phone.

Questions, or to have your data deleted by email: altitudedevlabs@gmail.com. Include your hunter name, shown in Settings.

Our website

altitudedevlabs.com has no accounts, no cookies, no analytics and no advertising trackers. Its pages load their fonts from Google Fonts, so Google sees your browser's internet address when you open them (see Google's privacy policy). Our server sees the same as for the game, above.

Children

MonstersDuko is a horror-themed game and is not aimed at children under 13. We don't knowingly collect anything more from children than described above.

Changes

If the game starts sending anything new, this page will say so before the update that does it, and the date at the top will change.
