This Privacy Policy explains how Kuusisto.tech ("we", "us") handles information in connection with the mobile game Saunamestari (the "App") for iOS and Android. Kuusisto.tech is operated by Mika Kuusisto, an independent developer based in Finland, and is the data controller for the purposes described below.
Saunamestari has no account system, no sign-up, and no login. We do not directly collect your name, email address, or other contact details through the App itself. The table below summarizes the categories of data processed by the App and the third-party services it relies on.
| Category | Examples | Source | Purpose |
|---|---|---|---|
| Game progress | Level reached, upgrades, in-game currency, settings | Stored locally on your device only | Save your game between sessions |
| Advertising identifiers | Device advertising ID (IDFA / GAID), coarse device & app info | Google AdMob (and its ad-tech partners) | Show interstitial and rewarded ads; in the EEA/UK, ad personalization only after consent via Google's User Messaging Platform |
| Purchase data | Anonymous app user ID, product purchased, transaction/receipt data | Apple App Store / Google Play, processed by RevenueCat | Unlock the "ad-free" purchase and support "Restore purchases" |
| Local notification schedule | Scheduled reminder times | Stored locally on your device only (flutter_local_notifications) | Optional daily-reward reminder |
We do not operate our own analytics or crash-reporting servers inside the App, and we do not sell your data.
Saunamestari shows ads served by Google AdMob between shifts, plus an optional rewarded ad you can choose to watch for an in-game bonus. AdMob and its partner networks may collect device identifiers and usage data to serve and measure ads, and may use this data across other apps and services in line with their own privacy policies. Where required (for example in the EEA, UK and Switzerland), a consent prompt is shown before any personalized advertising or non-essential data collection occurs, in line with Google's EU User Consent Policy. You can review or withdraw consent choices through that prompt, and manage ad personalization at the device level via your iOS or Android settings.
The optional "ad-free" purchase is processed entirely by Apple's App Store or Google Play, and purchase/entitlement state is synced through RevenueCat, our subscription and purchase management provider. RevenueCat receives an anonymous, app-specific user identifier and transaction data needed to validate your purchase and let you restore it on other devices — it does not receive your name, payment details, or contact information.
Your game progress, preferences, and scheduled local reminders are stored only on your device (via shared_preferences and local notification scheduling) and are not transmitted to us. Uninstalling the App removes this data, unless your device platform separately backs it up (e.g. iCloud or Google device backup), which is controlled by your own device settings, not by us.
Saunamestari contains dark comedic humor, cartoon depictions of alcohol (e.g. beer cans), and mild innuendo aimed at an adult sense of humor. It is not directed at children, and we do not knowingly collect data from children under the age of 13 (or the relevant minimum age in your country). If you believe a child has provided us with personal data, contact us using the details below and we will take appropriate action.
If you are located in the European Economic Area, the UK, or another jurisdiction with similar data protection laws, you may have the right to access, correct, delete, or restrict processing of your data, to object to processing, and to data portability, to the extent we hold such data. Because most game data lives only on your device and purchase/ad data is held by Google and RevenueCat as described above, some requests may need to be directed to those providers as well. You also have the right to lodge a complaint with your local supervisory authority — in Finland, the Office of the Data Protection Ombudsman.
Google and RevenueCat operate infrastructure globally, which means data they process may be transferred to and processed in countries outside your own, including outside the EEA. Where applicable, these providers rely on recognized safeguards such as Standard Contractual Clauses.
We do not retain a copy of your device-local save data. Advertising and purchase data is retained by Google and RevenueCat in line with their own retention policies. You can request deletion of purchase-related records tied to your anonymous app user ID by contacting us; we will forward verified requests to RevenueCat as needed.
We may update this Privacy Policy from time to time, for example to reflect changes in the App or in applicable law. Material changes will be reflected by updating the "Last updated" date above. Continued use of the App after an update constitutes acceptance of the revised policy.
