TubeSort

Privacy policy

25 October 2026

This page describes TubeSort for iPhone and Android and the leaderboard at tubsort.citengam.com. The operator is CitenGam. Contact: contact@citengam.com.

A postal address is not published here. This needs confirmation if the law that applies requires one.

Data on the phone

The game saves progress on the device. That includes the level, coins, nickname, language, sound, vibration, color marks, owned backgrounds and tube designs, the selected look, helper counts, the Remove ADS flag, the one-time Remove ADS bonus, and ad counters. Sign in with Apple can also leave an Apple session on the device. The Apple account name can be kept there so the game can send it to the leaderboard.

Data on the leaderboard

When the iPhone is signed in with Apple and can reach the server, TubeSort stores:

• the Apple user identifier from the Sign in with Apple token, not the Apple email address
• the Apple account name, which is kept and is not shown
• the Game Center name, if the game sends one
• the nickname, if you set one
• level and coins
• a session token, stored so the same phone can reconnect for 30 days after the last successful leaderboard request

The list shows the Game Center name, or the nickname if the player chose one. The Apple account name is kept and is not shown. A nickname is optional, has 5 to 15 characters, has no spaces, and is unique without regard to capital letters. The Game Center name may contain spaces and is not unique.

The score is also submitted to Game Center. That list is Apple's, separate from the list stored here. There is no Google sign-in. A Google token sent to this leaderboard is rejected.

Support requests

The support form sends your email address, and the text you type, to contact@citengam.com. Do not send passwords, Apple tokens, or payment card numbers. How long those emails are kept needs confirmation from the operator.

Ads

TubeSort asks for Google consent through Google Mobile Ads. If that form does not appear, the game does not treat the absence as a yes. On iPhone, Apple then asks whether the app may track. The game still runs if you refuse. Google and its advertising partners may use a device identifier to measure ads.

The ad between levels starts at level 4 and then appears every third level. Levels 5, 10, and then every 25th level are exams and never show that ad. The ad disappears after Remove ADS. Optional shop ads remain: 50 coins at most 3 times a day, an empty tube every 6 hours, and undo every 4 hours. The reward is given only after the ad finishes. The game uses Google's test ad units. Real AdMob ads are not connected yet.

Purchases

On iPhone, purchases go through Apple. This site does not receive your card number. Remove ADS costs €4.99. It stops the ads between levels and adds 1000 coins and 5 empty tubes once. It does not add undos. When the app opens again, the purchase is recognized and that bonus is not added a second time. There is no Restore Purchases button. Optional ads in the shop remain. On Android, purchases will go through Google Play when that version is published. They are not available now.

Coin packs are consumable. Apple does not give them back after they have been delivered. The coins stay in the progress on the phone.

Backgrounds and tube designs bought with money stay with Apple. After reinstalling, the app applies them when Apple confirms the purchase again. If they do not appear, open the same product in the shop. Apple does not charge a second time for a product you already own. There is no Restore Purchases button.

Why the data is used

• to run the game, the shared leaderboard, and the session that reconnects the phone
• to show the nickname you chose, or the Game Center name
• to answer support messages
• to show and measure ads
• to limit repeated requests

For people in the EEA or the UK, the legal basis for each purpose still needs confirmation from the operator. This page is not that legal assessment. The country of this leaderboard server is not stated here and needs confirmation if a law requires it to be named.

Who receives data

• CitenGam, as the operator of the leaderboard and the contact mailbox
• Apple, for Sign in with Apple, Game Center, and purchases
• Google and its advertising partners, through Google Mobile Ads, for the test ads and the consent tools in the app

The leaderboard records are not sold.

How long data stays

• The player row stays until the signed-in app deletes the account.
• The server session for the leaderboard is removed with that deletion. Otherwise it expires 30 days after the last successful leaderboard request.
• Rate-limit counters are hashes, not the leaderboard profile, and old counters are removed after about a day.
• Email retention needs confirmation.
• With Apple signed in, deleting the account in the game deletes the saved progress on that phone immediately, signs out, and stops saving. Purchases stay with Apple. Without an Apple account, the same screen deletes only the progress on that device.

Your choices

You can play without a nickname. You can refuse tracking when Apple asks. You can ask for access, correction, or deletion by writing to the contact address. Where the law gives you a right to complain to a privacy authority, that right is not removed by this page. This site does not promise a response time.

Deletion

Deletion is done in the game, at Settings → Delete account. With Apple signed in, local progress is deleted immediately, the account signs out, and saving stops. DELETE /api/account deletes the leaderboard row: the name, the level, and the coins. Purchases stay with Apple. Without an Apple account, the same screen deletes only the progress on that device.

This website

The public pages do not load third-party fonts or scripts. A language choice is stored in a cookie on this site so the same language opens next time. The server keeps a PHP error log with error messages, not with form contents or Apple names.

Still to confirm

• A postal address, if the law that applies requires one. This needs confirmation.
• The country of the leaderboard server, if it must be named. This needs confirmation.
• How long support emails are kept. This needs confirmation.
• The legal basis for each purpose for people in the EEA or the UK. This needs confirmation.
