Privacy Policy for Yajilin

Last updated: 23 August 2026

This policy explains what happens to your data when you use Yajilin (the “app”). It is written to describe what the app actually does, not what it might do one day.

Who is responsible

Yajilin is published by an independent developer. For any question about this policy or your data, write to info@e2sstudio.com.

What stays on your device

The app stores the following locally, using your device’s own storage:

• which puzzles you have solved, and your position in the endless mode
• which daily puzzles you have completed
• whether you have bought “Remove ads”
• counters used to decide when to show an ad

This information never leaves your device through us. It is removed when you uninstall the app or clear its data.

Advertising

The app shows full screen ads and rewarded ads through Google AdMob. To serve those ads, Google may collect and process data such as your device’s advertising identifier, IP address, device and operating system information, and information about how you interact with ads.

Google is an independent controller of that data. Their practices are described here:

• Google Privacy Policy
• How Google uses information from partner sites and apps

Your choice about personalised ads. Where required by law, the app shows a consent form when it first runs and requests ads accordingly. On iOS, the system also asks whether the app may track you across other companies’ apps and websites. If you do not consent, or if you decline tracking, the app requests non personalised ads instead. Non personalised ads still involve some data processing by Google, for example to limit how often you see the same ad and to prevent fraud.

You can change your mind at any time:

• iOS: Settings, then Privacy and Security, then Tracking
• Android: Settings, then Google, then Ads, where you can also reset or delete your advertising ID

Purchases

“Remove ads” is a one time purchase. The transaction itself is handled by the App Store or Google Play. We never see your card or payment details.

We use RevenueCat to check whether a purchase is valid and to restore it if you reinstall the app or change device. For that purpose RevenueCat receives a randomly generated app user identifier, purchase receipt information, and basic device and country information. See the RevenueCat privacy policy.

Because the app has no accounts, restoring a purchase works through your App Store or Google Play account, not through us.

What the app does not do

• No account, no sign in, no email collection
• No analytics or usage tracking by us
• No crash reporting
• No location access
• No contacts, photos, microphone, or camera access
• We do not sell data. We do not receive your personal data at all.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the ad or purchase services listed above, contact us at info@e2sstudio.com and we will help you reach the relevant provider.

Your rights

Depending on where you live, you may have the right to access, correct, delete, or object to the processing of your personal data. Since we do not hold personal data ourselves, such requests usually need to go to Google or RevenueCat, whose policies are linked above. Write to us at info@e2sstudio.com and we will point you to the right place.

You can always:

• withdraw or change your advertising consent, as described under Advertising
• remove ads entirely by buying “Remove ads”
• delete everything the app stored by uninstalling it

Changes to this policy

If the app starts doing something different with data, this page changes before that version reaches the stores, and the date at the top is updated.
