Privacy Policy
Reborn as a Startup Junior Developer · Effective October 20, 2026
The One and Only Engineer team ("we") makes this web game. We do not ask for your name, email or any contact details. With your permission we collect anonymous play data to improve the game, and we receive feedback only when you send it. This page explains what is sent, where it goes and how to turn it off.
1. Why we process data
- To improve the game: usage statistics such as where players stop and which choices or quizzes are hard
- To receive and act on feedback and quiz error reports
2. What we collect
Anonymous play data, only if you allow it (the English version asks first; nothing is sent before you choose "Allow")
- A random anonymous ID (for example
p_x7k2…) that is not linked to your name - Game progress: chosen role and industry, cards shown and choices made, quiz results, in-game year, ending, play time, the step where you stopped, and the text of buttons or links you click
- Device and visit details: browser and device type, screen size, language, approximate location (city level), and how you arrived (utm values of shared or ad links, the referring site)
- Session replay with all on-screen text masked, so only layout and movement are recorded
- Cookies: Google Analytics
_ga·_ga_*, AmplitudeAMP_*
Only when you send it: what you write in "Send feedback" or a quiz error report, your rating, the game situation at that moment (year, role, ending, etc.), browser details, and your anonymous ID if play stats are on.
Only when you tip: the "Buy us a coffee" button (shown on phones only) opens KakaoPay. KakaoPay processes the payment, and we only see the sender name and amount that KakaoPay shows us.
Kept on your device and never sent: your save (including the player name you typed), codex, records and settings, stored in your browser's localStorage.
When the game loads, fonts (Google Fonts) and the analytics script are downloaded from Google's servers, which receive your IP address and browser details.
3. Legal basis
For visitors covered by the EU/UK GDPR, anonymous play data is processed on the basis of your consent (Art. 6(1)(a) GDPR). Feedback you send is processed to answer and act on it at your request.
4. How long we keep it
- Anonymous play data: deleted automatically by each tool's retention settings, after 1 year in Amplitude and at most 14 months in Google Analytics
- Tip sender name and amount: used only to confirm the tip and not kept separately. The transfer record stays with KakaoPay under its own terms
- Feedback and error reports: deleted within one year of receipt, after we have acted on them
- When you ask us to delete your data, we delete the records for your anonymous ID without delay
5. Service providers and transfers outside your country
We use the following providers, all located in the United States. Data is sent over the internet while you play.
| Provider | Purpose | Data | Contact |
|---|---|---|---|
| Google LLC (USA) | Usage statistics (Google Analytics), feedback storage (Google Sheets), fonts | Anonymous play data, feedback, visit details | policies.google.com/privacy |
| Amplitude, Inc. (USA) | Usage statistics, text-masked session replay | Anonymous play data | amplitude.com/privacy |
| Vercel Inc. (USA) | Hosting, cookieless visit statistics | Visit details (page, referrer, region, browser) | vercel.com/legal/privacy-policy |
We do not sell or hand over your data to anyone else.
6. Cookies, local storage and how to say no
- Choose "Decline" on the first screen, or turn off Settings → Play stats at any time. Sending stops immediately and the analytics cookies and anonymous ID are deleted. Withdrawing consent is as easy as giving it, and the game works the same either way.
- You can also clear or block cookies and site data in your browser. This may also delete your save and codex.
7. Your rights
You can ask to access, correct or delete your data, or to stop its processing. Email team.coply@gmail.com. Because records are only tied to an anonymous ID, please include the ID shown in Settings. If you are in the EU/UK, you may also lodge a complaint with your local data protection authority.
8. Security
We collect only what we need and never send direct identifiers such as your name. Analytics accounts are limited to team members and protected with two-factor authentication. All traffic uses HTTPS.
9. Contact
The One and Only Engineer team · Email team.coply@gmail.com
You can also use "Send feedback" in the game. We reply within 10 days.
10. Changes
If this policy changes, we will update the effective date and ask again in the game.
