Privacy Policy for Kadak: Idle Chai Empire

Last updated: October 20, 2026

TappStudio ("TappStudio," "we," "us," or "our") makes Kadak: Idle Chai Empire (the "Game"), a free idle game for Android and iOS in which you grow a roadside chai stall into a chain of outlets. This Privacy Policy explains what information the Game collects, why, who receives it, and the choices you have.

Kadak has no accounts, no sign-in and no game server of our own. Your progress lives on your device. We have designed the Game to collect as little as possible.

By using the Game you agree to this Policy. If you do not agree, please do not use the Game.

1. Summary

No account, no name, no email, no phone number. You never give us your identity to play.
Your game save is stored on your device, and optionally in your Google Play Games or Apple Game Center cloud save.
Analytics and crash reports use a random anonymous ID, not your name, and not your device's advertising ID. You can switch analytics off in Settings.
Purchases are handled by Apple or Google. We never see your card or bank details.
Ads are optional. The Game only shows a video if you tap to watch one for a reward. There are no banners and no pop-up ads.
We do not sell your personal information.
The Game is for people aged 13 and over.

2. Information We Collect

2.1 Information stored on your device

Your game progress (stalls, upgrades, currencies, settings, tutorial progress, timers and a random install ID) is saved in files on your device. This stays on your device unless you turn on cloud save (Section 4.4). Uninstalling the Game deletes it, unless a cloud save exists.

2.2 Analytics, error reports and remote configuration (PostHog)

We use PostHog to understand how the Game is played, to find and fix crashes, and to change game settings (such as events, seasons and offers) without a new app release. PostHog may receive:

A random, anonymous ID generated by the Game
Game events such as tutorial steps, stalls unlocked, outlets opened, session start and purchases (a small number of events per player per day)
Error and crash reports, with technical context such as the app version, device model, operating system version and recent log lines (which contain game ids and counts, never personal data or purchase tokens)
Approximate region and IP address, which PostHog receives as part of any internet request. We do not use these to identify you.
The group of an experiment you were placed in, when we test two versions of a feature

PostHog may record a replay of the game's screens during a session to find bugs; the game's screens contain no personal information.

We do not collect your contacts, photos, microphone, camera, precise location, or messages.

You can turn analytics off in Settings inside the Game. Crash and error reporting that is necessary to keep the Game running may be limited when you do so.

2.3 Purchases (RevenueCat, Apple App Store, Google Play)

If you buy something, the transaction is processed by Apple or Google. Our subscription and purchase provider, RevenueCat, receives a purchase and entitlement record (product, purchase status, transaction identifier and a random app user ID) so we can unlock what you bought and let you restore it on a new device. We do not receive your card number, bank details or billing address.

2.4 Advertising (Google AdMob)

The Game offers optional rewarded videos, shown only when you tap to watch one. These are served by Google AdMob. To show an ad and to prevent fraud, Google may collect device and ad-related information such as your IP address, device identifiers, and ad interaction data, according to Google's own policies. Where the law requires it (for example in the EEA, UK and some other places) we show a consent prompt before ads are requested, and you can change your choice later. On Android, Google AdMob may use your device's advertising ID, which you can reset or delete in Android settings. We do not run banner or full-screen interstitial ads.

2.5 Leaderboards, achievements and cloud save (Google Play Games, Apple Game Center)

If you choose to use these features, Google Play Games Services or Apple Game Center handles sign-in, your player name, scores, achievements and cloud save under their own privacy policies. We receive the score or achievement you submit and, for cloud save, the save file you upload to your own Google or Apple game storage. These features are optional.

2.6 Notifications

The Game can send local notifications (for example, when a training timer finishes). They are scheduled on your device and do not need an account. We limit them in number and respect quiet hours. You can switch them off in Settings or in your device's system settings.

2.7 Messages you send us

If you email us, we receive your email address and whatever you write, and we use it only to reply and to improve the Game.

3. How We Use Information

To run the Game, restore your progress and honour your purchases
To show optional rewarded videos and pay for the Game through them
To understand where players get stuck, balance the game, and test improvements
To detect, fix and prevent crashes, bugs, fraud and abuse
To provide customer support
To comply with legal obligations

We do not use your information to build advertising profiles of our own, and we do not sell it.

We share information only with the service providers needed to run the Game, and only what each needs:

Provider	Purpose	Data involved
PostHog	Analytics, error tracking, remote configuration, experiments	Anonymous ID, game events, error reports, device and app info
RevenueCat	Purchases, subscriptions, restore	Anonymous app user ID, purchase and entitlement status
Apple App Store / Google Play	Payment and billing	Handled entirely by Apple or Google
Google AdMob	Optional rewarded video	Device and ad-related information per Google's policies
Google Play Games Services / Apple Game Center	Leaderboards, achievements, cloud save	Player profile, scores and save data you choose to sync

We may also disclose information if the law requires it, to protect our rights or the safety of users, or as part of a sale or merger of our business (in which case we will update this Policy).

4.1 International transfers

These providers run servers in various countries, including outside India. By using the Game you understand that your information may be processed in countries other than your own, under the safeguards of those providers.

5. Data Retention

On-device data stays until you delete the Game or use Delete my data in Settings.
Analytics and error data is kept only as long as needed for the purposes above, and in any case no longer than the retention period of our analytics provider.
Purchase records are kept as long as needed to honour purchases and to meet tax and accounting rules.
Emails to support are kept as long as needed to resolve your request.

6. Your Choices and Rights

Turn off analytics in Settings.
Turn off notifications in Settings or your device.
Change ad consent where a consent prompt applies, and use your device's ad settings.
Delete your data using Settings → Delete my data, which removes your local save, your cloud save and resets your analytics ID. See our Support and data deletion page.
Access, correct or erase information we hold about you, or withdraw consent, by emailing us. Because the Game has no accounts, we may need you to share a purchase receipt or the analytics ID shown to you so we can find your record.

If you are in the EEA, UK or Switzerland, you have rights under the GDPR, including to complain to your data protection authority. If you are a California resident, you have rights under the CCPA/CPRA; we do not sell or share personal information as those terms are defined. If you are in India, we handle your personal data in line with the Digital Personal Data Protection Act, 2023, and you may exercise your rights of access, correction, erasure and grievance redressal by writing to the contact in Section 10. If we do not resolve your grievance, you may approach the Data Protection Board of India.

7. Children

Kadak is intended for people aged 13 and over. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has used the Game, contact us and we will delete the related data.

If you are under 18 (or under the age of majority where you live), please use the Game, and especially any purchase, only with the permission and supervision of a parent or guardian. Parents and guardians can disable purchases in the Apple and Google store settings.

8. Security

Your save file is protected against corruption with a checksum and a backup copy. Data sent to our providers travels over encrypted connections. No system is perfectly secure, and we cannot guarantee absolute security.

9. Changes to This Policy

We may update this Policy as the Game changes. When we make a material change we will update the "Last updated" date above and, where appropriate, tell you in the Game. Using the Game after a change means you accept the updated Policy.
