Privacy Policy

Saku · Erek Studio

Short version: Saku has no accounts and we log nothing about you — everything you do stays on your device. The free version shows ads from Google AdMob, and Google processes device data to serve them. The one-time Studio Unlock removes the ads, and for buyers the ad SDK is never started.

What we collect

We — Erek Studio — do not collect, store, or transmit any personal data. There is no sign-up, no profile, and no account. The one exception is the advertising in the free version, where Google processes data we never see or store; see “Advertising” below.

Data stored on your device

Saku saves a few things locally so the app remembers your choices:

Your settings (theme, haptics, error-guard, accent palette).
Whether you have purchased the one-time Studio Unlock.

This information never leaves your device and is removed if you delete the app.

Advertising

Free play is ad-supported: a short ad before a puzzle opens, plus an optional ad you can choose to watch for a single hint. Ads are served by Google AdMob. To do that, Google processes your advertising identifier, an approximate region derived from your IP address, device and app information, and your interaction with the ad, under Google's privacy policy. We only ever see aggregate revenue reporting — never anything about an individual person.

In the EEA, Switzerland, and the UK, a Google consent form (UMP) asks for your choice before the first ad loads. You can change it at any time from Settings → Privacy options in the app. On iOS the system additionally asks whether the app may track you across apps and websites; if you decline, you still see ads, but they are not personalized.

The one-time Studio Unlock removes advertising completely. For buyers the ad SDK is never initialized, and neither the consent form nor the iOS tracking prompt appears.

Network & third parties

Puzzles are still generated and solved entirely on your device — playing needs no connection. Network requests come only from the advertising in the free version, which is why the Android build now holds the internet and advertising-ID permissions. Saku bundles no analytics or crash-reporting SDKs.

Purchases

The optional Studio Unlock is processed by the Apple App Store or Google Play. Saku never sees your name, email, or payment details — those are handled entirely by Apple or Google under their own privacy policies.

Children

Saku is not directed at children and collects no data of its own. The free version does show ads, however, and an ad can lead to an external site. The one-time Studio Unlock removes advertising for anyone who would rather play without it.

Changes

If this policy ever changes, we will update this page and its effective date.
