Gulp Privacy Policy

Effective date: 2026-10-11 · Applies to the Android app “Gulp” (咕咚), package com.ikws4.gulp · Operated by IKGames

You can play the whole game without signing in. In that case we collect no personal information and your save is stored only on your device.
If you choose to register or sign in with an email address to turn on cloud saves, we store your email, an internal user ID and your cloud save (see section 1). You can delete them at any time.
The only third party in the game is Google AdMob, used to show rewarded video ads that you choose to watch. It processes some device and ad data to serve those ads (see section 2).
Gulp is intended for users aged 13 and over and is not directed to children. If you are under 13, please do not register an account. All ad requests use conservative settings and ask for non-personalized ads only.

1. What we collect ourselves

Without signing in: nothing

You do not need to register or sign in to play, and we never ask for your name, phone number or date of birth.
Game progress and settings are stored in the app's own storage on your device and are not uploaded to us.
The game does not request access to your location, camera, microphone, contacts or photos.

If you choose to register or sign in: account and cloud save

Accounts are optional and exist only so you can recover your progress on a new device or after reinstalling. Only after you register or sign in do we store, on our own server:

Data	Purpose
Email address	Signing in, password recovery, essential account notices
Password (stored only as a salted hash; we cannot see it)	Authentication
Internal user ID (randomly generated)	Linking your cloud save to your account
Your cloud game save and the time it was last updated	Syncing and restoring progress across devices
Access logs: IP address and request time	Preventing abuse and attacks, troubleshooting; kept for a short period and then deleted automatically

This data is never sold, never used for advertising, and never shared with Google AdMob or any other third party. We do not send marketing email.

The data is stored on our cloud server. All communication between the game and the server is encrypted with HTTPS.

Emails you send us

If you choose to email us, we receive your email address and the content of your message, which we use solely to reply and handle your request.

2. Third party: Google AdMob (Google Mobile Ads SDK)

Gulp is free and supported by rewarded video ads. An ad plays only when you tap a button clearly marked as “watch an ad”, and you receive an in-game reward for watching it. There are no interstitial ads and no banner ads.

Ads are provided by Google. To request and show ads, the Google Mobile Ads SDK built into the game collects and processes the following data directly. We do not receive this raw data; we only see aggregated statistics in the AdMob console, such as impression counts and revenue.

Data	Purpose
Device identifiers, such as the advertising ID (where permitted by the system and Google's policies) and app instance identifiers	Serving and displaying ads, frequency capping, measuring ad performance, preventing fraud and abuse, security, and diagnosing SDK problems
IP address, and the approximate location derived from it (country or city level, not precise location)
Device and app information: model, OS version, language, screen size, network type, app version and similar
Ad interaction and diagnostic data: ad impressions, taps, completion, and SDK performance and error information

How Google uses this data is described here:

The game contains no third-party SDK other than Google AdMob. Accounts and cloud saves run on our own server and do not pass through any third party. We do not sell your personal information.

3. Age requirement and minors

Gulp is intended for users aged 13 and over and is not directed to children. If you are under 13, please do not register an account. If the age of consent for processing personal data is higher than 13 where you live (for example 14 to 16 in parts of Europe) and you are below that age, please register only with the consent of a parent or guardian.

The whole game can be played without signing in, and in that case it collects no personally identifying information.
Accounts are optional. When registering you are asked to confirm that you are 13 or older. If we learn that we hold the email address or other personal information of a child under 13, we will delete the account and its cloud save.
All ad requests use conservative settings: they are tagged as coming from a user under the age of consent and the ad content rating is capped (see Google's explanation). With these settings Google does not serve personalized ads (interest-based advertising or remarketing); only non-personalized ads are shown.
We do not knowingly collect personal information from children under 13.

Parents and guardians: if you believe your child under 13 has provided personal information to us through the game (for example by registering an account) and you want to review or delete it, or you have any question about your child's privacy, email zhipingne@gmail.com and we will respond and act promptly.

4. How to reset or delete data

Local save: uninstall the game, or clear it under Settings → Apps → Gulp → Storage → Clear data. The save on your device is then permanently deleted.
Account and cloud save: in the game, open Settings → Account to sign out, delete your cloud save, or delete your account. You can also email zhipingne@gmail.com from your registered address. The steps and what gets deleted are on the Delete account page.
Advertising ID: on Android, go to Settings → Google → Ads (on some devices Settings → Privacy → Ads) to reset or delete your advertising ID.
Data held by Google: exercise your rights with Google as described in the Google Privacy Policy.
Emails you sent us: ask us and we will delete them.

5. Data retention

Not signed in: we store no player data. Your save remains on your device until you clear it or uninstall the game.
Account and cloud save: kept until you delete them or delete your account. Deletion requests are completed within 30 days.
Access logs: kept for a short period and then deleted automatically.
Ad data collected by Google: retained under Google's own policies.
Email: kept only as long as needed to handle your request.

6. Transfers and security

Account data and cloud saves are stored on our cloud server, sent over HTTPS, and passwords are stored only as hashes. Ad data is processed by Google on servers around the world, which may be outside your country or region. No system is perfectly secure; if an incident affects your data we will notify you as the law requires.

7. Your rights

Depending on where you live, you may have the right to access, correct or delete your personal information, or to object to or restrict its processing. Account data (email, cloud save) can be handled directly in the game under Settings → Account, or by emailing us. Ad data is held by Google, so those requests need to go to Google. If you are unsure how, email us and we will help.

8. Changes to this policy

If the way the game handles data changes (for example, if a new third-party service is added), we will update this page and the effective date above first. Significant changes will also be announced in the game or on its store page.
