SeolaSoft ("we", "us") operates the mobile game Jetstream: Airline Tycoon (package com.seolasoft.jetstream, the "Game"). This policy explains what information the Game processes, why, and how you can control it.
The Game has no sign-up and does not collect your name, email address, phone number, postal address, contacts, photos, or precise location. We process only an anonymous identifier and your game save so progress can follow you across devices, plus analytics and advertising identifiers used to improve the Game and serve ads.
| Category | What it is | Why |
|---|---|---|
| Anonymous account ID | A random string (UID) issued automatically by Firebase Anonymous Authentication. It is not linked to your real name or email. | To restore your saved progress after reinstalling or switching devices |
| Game save data | Your in-game state: cash, routes opened, aircraft owned, current year and quarter, era goal progress | Cloud save and restore |
| Usage analytics | In-game events (quarter settlement, route opening, ad views, etc.) and device information (device model, OS version, country/region, app version, language) | To improve game balance and usability, and to detect errors |
| Advertising identifier | Android Advertising ID (AAID) and ad impression/click records | Ad delivery, frequency capping, performance measurement, fraud prevention |
The Game does not collect: name, date of birth, email address, phone number, postal address, payment card details, contacts, call or SMS logs, photos or videos, microphone or camera data, precise (GPS) location, or a list of files on your device.
We use the information only for the purposes listed above. We do not sell your information, and we do not share it with anyone other than the service providers named in Section 3.
Game saves are written only to an area scoped to your anonymous identifier, and server security rules prevent other users from reading or modifying it. All transmission is encrypted (HTTPS/TLS).
The Game uses the following external services, each of which processes data under its own policy:
Game saves are stored in Google Cloud's Asia Pacific (Seoul, asia-northeast3) region. Analytics and advertising data may be processed on servers in countries where Google operates.
The Game is free and supported by advertising. Ads consist of rewarded ads, which you choose to watch, and interstitial ads, shown at natural transition points such as quarter settlement.
You can reset your advertising ID or opt out of ad personalization at any time in Settings → Google → Ads on your device. After opting out you will still see ads, but they will not be personalized to your interests.
We retain your game save and anonymous identifier for as long as you use the Game. To delete it:
See the Account & Data Deletion page for step-by-step instructions.
Analytics data is handled under Google Analytics' default retention policy and is aggregated in a form that does not identify individuals.
The Game is not directed to children. We do not knowingly collect personal information from children under 13 (COPPA) or under 14 (Republic of Korea). If we learn that we have collected such information, we will delete it without delay.
You may request access to, correction of, deletion of, or restriction of processing of your information. Contact us and we will respond within the period required by applicable law.
