ScrollKiller is a self-control app that helps people reduce mindless social media use on their own iPhone.
- Information We Collect
1.1 Subscription Information
If you buy or restore ScrollKiller Pro, we use Apple’s in-app purchase system and RevenueCat to show available plans, process purchases, restore purchases, and confirm whether Pro is active.
1.2 App Identifiers
ScrollKiller creates a random install identifier for subscriptions and a separate random referral identifier for Hug Rewards. These identifiers are random characters. They are not based on your name or email address.
1.3 App Analytics and Ads Measurement
ScrollKiller uses Google Analytics for Firebase and Google Ads measurement to understand how the app is used and which ads lead to installs, trials, or purchases.
Outside the United States, we may ask before enabling App analytics and Ads measurement. In the United States, App analytics and Ads measurement may be enabled by default, but you can turn them off anytime in ScrollKiller settings.
When App analytics or Ads measurement is enabled, data may include app opens, first opens, screen visits in our app, basic app events, trial starts, purchases, app version, device information, region/country, and a Firebase app instance identifier.
When App analytics or Ads measurement is not enabled, Google Consent Mode may still send limited signals about consent state and key app events for basic measurement and modeling. These limited signals are designed not to use app or device identifiers for analytics or ads storage.
We do not use this for personalized ads. We do not use IDFA. We do not use Google Ads remarketing.
We do not send your name, email address, selected blocked apps, selected blocked websites, hold messages, intentions, habits, raw location trail, or route history to Firebase Analytics or Google Ads.
1.4 Hug Rewards Information
If you use Hug Rewards, we store the information needed to run that feature, including your hug count, active hug sessions, claimed rewards, and reward history.
- Information We Do Not Send To Our Servers
2.1 Smart Detection Location And Motion
Smart Detection uses motion and coarse movement state on device to help decide when shielding should happen. We do not send your route history, place history, or raw location trail to our servers, Firebase Analytics, or Google Ads.
2.2 Family Controls Selections
The apps, websites, and categories you choose to limit are used on device through Apple’s Family Controls / Screen Time system. We do not send those selections to our servers, Firebase Analytics, or Google Ads.
2.3 Personal Content Created In The App
Intentions, habits, hold messages, and most settings are stored on your device unless you intentionally use an Apple system feature that shares them.

In regions where consent is required, you can continue using ScrollKiller without allowing App analytics or Ads measurement.

- Retention
Subscription-related identifiers are kept as long as needed to support purchases and restores.
Hug Rewards records are kept as long as needed to support rewards, prevent abuse, and maintain reward history.
Firebase / Google Analytics data is kept according to our Google Analytics retention settings.
On-device app content remains on your device unless you remove the app or clear it yourself.
- Legal Basis
For subscriptions and core app features, we process data to provide the app and paid features.
For abuse prevention, we process limited data to protect ScrollKiller and Hug Rewards.
For App analytics and Ads measurement, we ask for consent where required. In regions where consent is not required, we may use App analytics and Ads measurement for our legitimate interests or business purposes, and you can turn them off in ScrollKiller settings.
- Your Rights
Depending on where you live, you may have rights to access, correct, delete, or restrict the use of your personal data. You may also have the right to withdraw consent, opt out of certain uses, or complain to your local data protection authority.
