History Hunch · Last updated 14 October 2026
History Hunch is a history game for Android, iPhone and the web, made by Pedro Moreira (PTech Studio). This page explains what data the game uses, why, and the choices you have. In short: you can play without an account, your game history stays on your device, and we never sell your data.
Who is responsible
Pedro Moreira, PTech Studio, is the controller of your personal data. Contact: contact@ptechstudio.com.
What we collect and why
| Data | Why | Where it's kept |
|---|---|---|
| Your games: scores, answers, streaks, achievements, events discovered | To show your stats, streak and collection | Only on your device (in the browser's storage on the web). Deleted if you delete the app or clear the site's data. |
| Google account details, if you sign in: your Google account ID, name, email address and profile picture link | To give you a leaderboard account. Signing in is optional and only needed for the leaderboard. | Google Firebase Authentication |
| Leaderboard entries: your daily score, number of exact answers, the time you submitted, and your leaderboard name | To rank you against other players. Your leaderboard name and score are visible to everyone. By default the name is your first name and last initial (e.g. "Ada L."), or the nickname you choose. | Google Firebase (Cloud Firestore), stored in the European Union |
| Your nickname, if you set one | To show it on the leaderboard instead of your name | Google Firebase (Cloud Firestore), EU. Only you can read it; others see it only on leaderboard entries. |
| Usage data: games started and finished, scores, hints used, screens visited, sign-ins, shares; device type, operating system, app version, approximate location (country/region) and an app-instance identifier | To understand how the game is played and improve it (for example, where players stop) | Google Analytics for Firebase |
| Advertising data (Android and iPhone): device and advertising identifiers (only with your permission where required), IP address, device information and ad interactions | To show ads that keep the game free, measure them and prevent fraud | AppLovin and the ad networks it works with (for example Unity Ads) |
| Purchases (Android): whether you bought History Hunch Premium | To remove ads and unlock hints | Google Play. We never see your payment details. |
We don't collect your precise location, contacts, photos or microphone, and the game isn't designed to collect anything else.
Ads and your choices
The free versions on Android and iPhone show ads. If you're in the European Economic Area, the United Kingdom or Switzerland, the game asks for your consent before showing personalised ads, and you can still play if you say no (you'll see non-personalised ads). On iPhone, the game only uses your advertising identifier if you allow tracking when iOS asks. You can change these choices at any time in your phone's settings (Privacy → Tracking on iPhone; Settings → Google → Ads on Android).
The web version currently shows no real ads.
Legal bases (EU and UK)
- Contract: running your leaderboard account when you sign in.
- Consent: personalised advertising, and cookies or similar storage that aren't strictly necessary. You can withdraw consent at any time.
- Legitimate interests: keeping the game working and secure, and understanding in aggregate how it's played so we can improve it.
Who we share data with
Only the service providers that run parts of the game: Google (Firebase Authentication, Cloud Firestore, Analytics, Google Play), AppLovin and its ad partners, and Cloudflare (which hosts this website). Some of them process data outside the EU (for example in the United States) under the European Commission's standard contractual clauses or equivalent safeguards. We don't sell your personal data.
How long we keep it
- Game data on your device: until you delete the app or clear the site's data.
- Account and leaderboard data: until you ask us to delete it.
- Analytics data: up to 14 months, then deleted automatically by Google Analytics.
Your rights
You can ask to see, correct, export or delete your personal data, object to its use, or restrict it. To delete your account and leaderboard entries, email contact@ptechstudio.com from the address of your Google account; we'll do it within 30 days. You can also complain to your local data protection authority.
Children
History Hunch is meant for a general audience and isn't directed at children under 13 (under 16 in some EU countries). We don't knowingly collect data from children. If you believe a child has given us personal data, contact us and we'll delete it.
Changes
If this policy changes, we'll update the date at the top. For important changes, we'll also let you know in the game.
