Privacy Policy

Last updated 28 September 2026

This page covers every app published by SmallPaper on the Apple App Store and Google Play:

The policy is the same for every app under SmallPaper: we collect nothing ourselves. One app, 졸음탑 — Sleepy Tower (from version 1.2.0), can show an ad that you choose to watch. Those ads come from Google AdMob, the only third-party service in any of our apps, and are described under Advertising.

What we collect

Nothing. Our apps do not collect, transmit, or share any user data. The one exception is the advertising SDK inside 졸음탑, which is Google’s and is covered in its own section below.

Where your data lives

Everything an app remembers stays on your device — your ink recipes (Tinct), the Tawaf and Sa’i counter along with haptic and dua preferences (Septem), the last leather thickness, unit, project type and machine thread limit (Subula), brightness and eyes-closed settings (Verd), the °C / °F choice (Fornax), the week you are on, the lunchbox skins you have unlocked, your best score and the sound on/off setting (오늘의 도시락), and your best score with your top five results, the sound on/off setting, whether you have already seen the rule hint, and the tower you paused so you can keep stacking it later (졸음탑). It is kept in iOS / watchOS UserDefaults on Apple devices, and in the app’s private storage on Android.

It may be included in your device’s backup — iCloud Backup on Apple devices, Android Backup on Android — if you have that turned on. Those backups are controlled entirely by Apple or Google and your own device settings. They never pass through us.

Photos (Tinct only)

Tinct lets you attach a swatch photo to a recipe. The photo is processed entirely on your device and stored as part of your local recipe data. Photos are not transmitted anywhere.

Third parties

Apart from the advertising SDK in 졸음탑 described next, none of our apps include analytics SDKs, advertising networks, crash reporters, or third-party services of any kind.

Advertising (졸음탑 — Sleepy Tower only)

From version 1.2.0, 졸음탑 can show a rewarded video ad through Google AdMob. An ad plays only when you tap “Watch an ad to rescue” on the result screen; nothing plays on its own, and there are no banners. Watching it through lets you rewind your tower to the last moment every animal was asleep, at most three times per tower.

To serve and measure those ads, Google may collect information from your device: an advertising identifier (Apple’s IDFA or the Android advertising ID, only where you have allowed it), your IP address and the approximate location derived from it, device and app details, and how you interact with the ad. That data goes to Google, not to us; we only ever see aggregate numbers such as how many ads were shown. How Google uses it is set out in Google’s Privacy Policy and How Google uses information from sites or apps that use its services.

Your choices: on iPhone, the first launch asks whether the app may track you; choosing Ask App Not to Track keeps the advertising identifier from Google, and you can change it later in Settings → Privacy & Security → Tracking. On Android you can reset or delete your advertising ID in Settings → Google → Ads. In the EEA, UK and Switzerland the app shows Google’s consent form before any ad loads, and you can decline personalised ads there. Ads still work without an identifier; they are just less relevant.

졸음탑 is not directed at children under 13, and we do not tag its ads for child or under-age treatment.

Children

오늘의 도시락 — Today’s Lunchbox is intended for a general audience that includes children, and is listed for ages 6 and up. Our other apps are not directed at children under 13.

Because we collect nothing at all, this makes no difference to what happens to a child’s data: none of our apps collect, transmit, or share any data from anyone, including children. Apart from the optional rewarded ads in 졸음탑 (which is not directed at children), they contain no advertising, no analytics, no in-app purchases, and no links out to other services. This is consistent with the Google Play Families policy, COPPA, and the GDPR.
