Marine ETO is a study suite for ships' Electro-Technical Officers, for Android and the web. It is built to work offline at sea, and it is built to leave you alone: the app has no user accounts, no advertising, no analytics and no trackers, and it does not collect personal information.
Marine ETO က သင်္ဘောပေါ်မှာ အင်တာနက်မရှိလဲ သုံးလို့ရအောင် တည်ဆောက်ထားတဲ့ ETO လေ့လာရေး app ပါ။ အကောင့်ဖွင့်စရာမလို၊ ကြော်ငြာမပါ၊ analytics နဲ့ tracker လုံးဝမပါပါဘူး။ ကိုယ်ရေးကိုယ်တာ အချက်အလက်တွေကိုလဲ မစုဆောင်းပါဘူး။
Your study progress, quiz results, settings (language, theme) and your Pro activation are stored only on your own device. They are never uploaded anywhere. Uninstalling the app removes them.
လေ့လာမှု တိုးတက်မှု၊ မေးခွန်းရလဒ်၊ ဆက်တင်တွေနဲ့ Pro activation အားလုံးက သင့်စက်ထဲမှာပဲ သိမ်းထားပြီး ဘယ်ဆီကိုမှ တင်မပို့ပါဘူး။
The Google Play edition of the Android app makes no network connections at all. All study content is bundled inside the app, and activation codes are verified entirely on your device. Nothing is sent to us or to anyone else. The website edition of the Android app additionally fetches one small version file from our server to tell you when an update exists; that request carries no personal information either.
The web edition (running in your browser at lwinstudio1.com) talks to our server in exactly one case: when you redeem a purchase code, the code plus an anonymous device identifier (a random-looking code generated in your browser, containing no personal information) is sent once, to limit how many devices one purchase can activate. Like every web server, ours keeps standard technical logs (IP address, requested file, time) for security and troubleshooting; these are kept short-term and are not used to identify or profile anyone.
Android app က server နဲ့ လုံးဝ မဆက်သွယ်ပါဘူး — သင်ခန်းစာအားလုံး app ထဲမှာ ပါပြီးသားဖြစ်ပြီး activation code ကိုလဲ စက်ထဲမှာပဲ စစ်ပါတယ်။ Web version ကတော့ purchase code redeem လုပ်တဲ့အချိန် တစ်ကြိမ်တည်း — code နဲ့အတူ ကိုယ်ရေးအချက်အလက် မပါတဲ့ စက်သီးသန့် code တစ်ခုပဲ ပို့ပါတယ်။
The app itself never handles money. Pro licenses are purchased outside the app, so the app never sees or stores any payment details.
App ထဲမှာ ငွေပေးချေမှု လုံးဝမရှိပါဘူး။ Pro ကို app ပြင်ပမှာ ဝယ်တာဖြစ်လို့ ငွေကြေးအချက်အလက်တွေကို app က ဘယ်တော့မှ မမြင်ပါဘူး။
Marine ETO is professional maritime training software and is not directed at children. In any case, it collects no data from anyone.
If this policy ever changes, the new version will be published at this same address with a new date at the top.
