Trainquil

Privacy policy

What Trainquil collects, why, and what you can do about it. We’ve kept it short and plain.

Last updated 8 November 2026 · Singapore · For ages 13+

In short

You can play as a guest. If you sign in with Google, Apple or email, we keep your email and your progress so you can pick up where you left off.
The phone apps show ads from Google AdMob, and measure which of our own ads brought you to the game (Google Analytics for Firebase and Meta), only if you agree. No cookies, no precise location.
We never sell your data. Delete your account in Settings, or email support@kinetlab.games any time to see, correct or delete your data.

Who we are

Trainquil is made by Chakrit Thong Ek in Singapore, under the name KINET LAB. This policy covers the Trainquil apps for Android and iPhone, the browser version, and these web pages. Questions about your data go to support@kinetlab.games.

What we collect and why

What	Why
A random player ID	Created the first time you open the game, so your progress belongs to you without needing an account
Your account, if you sign in: email address, how you signed in (Google, Apple, or email and password), and a name if Google or Apple provides one	To sign you in and keep your progress safe on a new phone. With email sign-in, Google’s Firebase keeps your password for us; we never see it
Your game: levels cleared, stars, coins, boosters, hints, undos, settings, and the looks you’ve bought	To save and restore your game. It’s kept on your phone and backed up in the cloud
Your moves on each level you clear, and a record of the coins and boosters you earn and spend	So our server can check rewards are earned fairly before adding them to your account
Ads in the phone apps: your device’s advertising ID, which ads were shown or watched, your ad consent choices, IP-based approximate region, and ad performance and crash information (handled by Google AdMob)	To show ads, give you the reward when you choose to watch one (Google confirms the watched ad to our server), and prevent ad fraud
Purchases, when the app offers them (Remove Ads, coin packs): the product, the store’s order or transaction ID, and refund notices from the store	To check the purchase with Google Play or the App Store, deliver what you bought, and take it back if it’s refunded. The store takes the payment; we never see your card details
App activity in the phone apps, only if you agree to ads measurement: that the app was installed and opened, purchases made, your device’s advertising ID (on iPhone only if you allow tracking), app instance ID, device model, OS version and IP-based approximate region (handled by Google Analytics for Firebase and Meta)	To learn which of our ads bring players to Trainquil, so we can spend on the ones that work, and to understand how the game is used
Messages you send us	To reply and to improve the game
IP address and basic device and network details, handled by our hosting and sign-in providers	To deliver the game and these pages, and keep them secure

We never see your password: Google, Apple and Firebase handle sign-in, including email sign-in. Trainquil doesn’t ask for your location, contacts, photos, camera or microphone.

On your phone and in the cloud

Your progress and settings are saved on your phone, which is how you can play offline, and backed up in the cloud. If you sign in, a new phone can bring your progress back. Uninstalling the app removes the copy on your phone, but not the cloud backup.

Who else is involved

We use Google Firebase for sign-in, cloud saves and the server that checks rewards and purchases, Google AdMob for ads, Google Analytics for Firebase and Meta to measure our own ads, and Google Play or the App Store for purchases. They process data under their own terms: see Firebase privacy, Google’s privacy policy, Meta’s privacy policy and Apple’s privacy policy. We only share data when the law requires it, to protect people or the service, or if the game changes hands, in which case we’ll tell you first. We don’t sell your personal information.

The phone apps show ads served by Google AdMob: ads between levels, and rewarded ads you choose to watch for a bonus. AdMob uses your device’s advertising ID and may personalise ads; see how Google uses information from apps that use its services. If you’re in the UK, the EEA or Switzerland, the app asks for your consent before showing personalised ads, and you can change that choice in Settings → Ad privacy choices. On iPhone, the app asks Apple’s tracking question first; saying no means ads aren’t personalised with your advertising ID. You can also reset or delete your advertising ID in your phone’s settings. Remove Ads turns off the ads between levels for 30 days.

Measuring our own ads. We advertise Trainquil on Google and Meta (Facebook and Instagram). To learn which ads work, the phone apps tell Google Analytics for Firebase and Meta when the app is installed and opened and when a purchase is made, with your advertising ID where you allow it. This only starts after you agree on the ad consent screen (or where no consent screen is needed), and on iPhone the advertising ID is only used if you allow tracking. You can change your choice in Settings → Ad privacy choices, or turn off ad tracking in your phone’s settings.

How long we keep it

We keep your account and cloud save while you use the game, and delete them when you delete your account. We keep messages while we need them to help you, and purchase records (when we have them) as long as the law requires. Our providers may process data outside Singapore; we make sure it’s protected as the law requires.

Your choices

To delete your account and cloud save, go to Settings → Account → Delete account in the app, or see deleting your account. You can also email us to see or correct your data. Depending on where you live, you may also be able to object to some uses, limit them, or get a copy of your data. Never send us a password.

If you’re unhappy with how we’ve handled your data, you can contact Singapore’s Personal Data Protection Commission or the regulator where you live.

Younger players

Trainquil is for players aged 13 and over. If you’re under the age at which you can agree to this yourself where you live, ask a parent or guardian first. If you think a child under 13 has given us personal information, email support@kinetlab.games and we’ll remove it.

Changes to this policy

If we change how we handle data, we’ll update this page and the date at the top. Where the law requires it, we’ll also tell you directly or ask for your consent.
