Privacy Policy

Last updated: September 28, 2026

Oplin Studio ("we", "us") makes the apps Ducksy and Lag Lag. We don't require an account. Ducksy collects no data at all. Lag Lag shows ads, and with your permission those ads can be personalized. This policy explains what each app handles and why.

Ducksy

Ducksy stores your settings and focus-session progress on your device only. We don't collect or transmit this data.

Lag Lag

Quote content

Lag Lag downloads its quote catalog using Google Firebase Remote Config. To deliver this content, Firebase uses an app instance identifier and basic device information such as app version, OS version, and language. This data is used only to deliver content. It isn't linked to your identity or used for advertising. See Firebase's privacy information.

Advertising

Lag Lag shows ads through Google AdMob. To serve and measure ads, AdMob collects:

Lag Lag asks your permission before tracking you. If you tap Allow, Google may use the IDFA to show ads based on your activity across other companies' apps and websites. If you tap Ask App Not to Track, you still see ads, but they aren't personalized with the IDFA. You can change this anytime in Settings → Privacy & Security → Tracking.

Learn how Google uses this data at How Google uses information from sites or apps that use our services.

Photos

If you choose to save a quote image, Lag Lag asks for permission to add photos to your library. It can't read your existing photos. If you attach a screenshot to feedback, only the image you pick is used.

Purchases

Subscriptions and in-app purchases are processed by Apple. We never see your payment details. We only receive confirmation of whether a purchase is active.

Feedback

If you send feedback, we receive your message and any contact details or attachment you choose to include. We use them only to reply and to improve the app.

Children

Our apps are not directed at children under 13, and we don't knowingly collect personal information from them.

Your choices

You can delete all app data at any time by deleting the app. To ask about, or request deletion of, feedback you've sent us, email support@oplinstudio.com.

Changes

If this policy changes, we'll update this page and the date above.
