Privacy Policy
This policy describes how the EpicTango app
(br.com.hiveagent.epictango) handles personal data.
1. Who the controller is
IMPETUS DESENVOLVIMENTO DE SISTEMAS LTDA - ME, company tax ID (CNPJ) 42.188.156/0001-98, Rua Espanha, 50 — Vila Santa Maria, Americana/SP, CEP 13471-613.
Contact for privacy matters and for exercising your rights, including with the data protection officer: [email protected]
2. An honest summary
EpicTango is a logic game. It does not ask for your name, your email, your location, your calendar, your photos, your camera or your microphone. You can install and play without creating an account and without entering any personal data.
What does exist is: a random identifier to keep your progress, the data Google uses to show ads and, only if you choose to, your Google account — which carries your progress and purchases to another device.
3. Data we handle
3.1 Anonymous identifier
On first launch the app generates a random identifier (UUID) and an anonymous Firebase Authentication account. This identifier contains and derives from no personal data of yours — it is a random number whose only job is to tie your progress to your device.
It is lost if you uninstall the app or clear its data.
- Purpose: to keep and sync your progress.
- Legal basis (LGPD, art. 7, V): performance of the service you requested.
3.2 Game progress
Daily-challenge results (date, whether solved, time), journey progress (levels completed and times) and practice statistics.
These stay on your device and are mirrored to Firebase Firestore, tied to the anonymous identifier in section 3.1.
- Purpose: to avoid losing progress and to let you continue on another device.
- Legal basis: performance of the service.
3.3 Data stored on your device
Preferences, game state and your coin wallet — balance, purchased items and the daily usage counters — stay in the app's local storage. They are not tracking cookies and are not shared.
3.4 Advertising (Google AdMob)
The app shows Google AdMob ads. For that, Google may handle:
- Android advertising identifier (Advertising ID)
- IP address and approximate region derived from it
- Device information (model, operating system, language)
- Ad interactions (impressions, clicks, videos watched)
This data is collected by Google, as its own controller, under its policies. We do not receive, store or have access to this data in any individualized form — we see only aggregated performance reports.
- Purpose: to sustain the free app.
- Legal basis: consent where required, and legitimate interest otherwise.
- How to limit it: you can reset or delete your Advertising ID in Android Settings → Google → Ads.
- Google's policy: policies.google.com/technologies/ads
3.5 Remote configuration
The app queries Firebase Remote Config for operating parameters, such as coin prices, daily limits and the minimum version. This request sends standard technical request data, such as IP address and app version. No game data is sent.
3.6 Google account, when you choose to link it
If — and only if — you choose to link your Google account, the app starts handling that account's identifier and the email address tied to it.
This is optional. Declining does not prevent playing or buying; the only consequence is that your progress and items stay tied to the device and are lost if you switch phones or reinstall.
The app does not request access to your contacts, calendar, files or any other data from your Google account. The email is used only to identify your record and to answer your requests.
- Purpose: to sync progress and purchases across devices.
- Legal basis: consent, given when you link the account.
3.7 Purchases and subscription
The game has a single coin, which you earn by watching rewarded videos or by buying a pack. With it you buy in-game items — extra checks, the timed validator and additional practice puzzles. There is also a subscription that removes ads.
Purchases are processed by Google Play. We never see, receive or store card details, Pix keys or any payment method.
We use RevenueCat to validate receipts and to know whether your subscription is active. For that, the anonymous identifier from section 3.1, the purchase token issued by Google and device data are transmitted.
- Purpose: to confirm the purchase is legitimate and unlock what you bought.
- Legal basis: performance of the purchase contract.
- RevenueCat's policy: revenuecat.com/privacy
4. What we do not do
- We do not sell personal data.
- We do not use your game data for advertising.
- We do not request camera, microphone, precise location, contacts, files or photo permissions.
- We do not build behavioral profiles beyond what AdMob does to show ads.
- We do not track you across third-party apps.
- We do not receive, see or store card details, Pix keys or any payment method — Google Play processes it.
- We do not require an account to play, and we do not charge to play.
5. Sharing
Your data is shared only with the processors needed for the app to work:
| Who | What | Why |
|---|---|---|
| Google Firebase | Anonymous identifier, game progress | Authentication and sync |
| Google AdMob | Data from section 3.4 | Showing ads |
| Google (sign-in) | Account identifier, email address | Optional linking and sync |
| Google Play | Transaction data | Processing purchases |
| RevenueCat | Anonymous identifier, purchase token, device data | Receipt and subscription validation |
There is no sharing with any other company, for any purpose.
6. International transfer
The services above run on servers outside Brazil, including in the United States. By using the app, your data is transferred to and handled on those servers, under the contractual safeguards of the respective providers (LGPD, art. 33).
7. Retention
- Game progress: kept while the app is installed and the record exists. You erase what is on the device by uninstalling the app or clearing its data.
- Purchase data: kept for the applicable legal and tax period, even if you delete the account — a legal obligation, not our choice.
- Advertising data: per Google's retention policies.
8. Your rights
Under the LGPD (art. 18) and the GDPR, you may request: confirmation of processing, access, correction, anonymization, portability, information about sharing, withdrawal of consent and deletion of your data.
Write to [email protected]. We reply within 15 days.
How to delete your account and your data
If you never linked your Google account: uninstalling the app or clearing its data erases everything on the device and lets the anonymous identifier be lost. Without it, the record kept in the cloud can no longer be tied to you or to any device. If you want that record erased from the server too, write to [email protected] — we will need your help to locate it, and we reply explaining how.
If you linked your Google account: request deletion through the Delete my account page, or write to [email protected]. We erase the cloud record and all game data within 15 days.
Deletion erases progress, statistics, coin balance and items. Purchase records are kept for the tax period, as the law requires, and an active subscription must be canceled by you in your Google Play account — we cannot cancel it.
9. Children
EpicTango is not directed at children under 13 and does not knowingly collect children's data. If you are a guardian and believe a child provided data, write to [email protected] and we will remove it.
10. Security
Data travels over encrypted connections (HTTPS/TLS). Database access is restricted by rules that let each user read and write only their own record.
11. Changes
Changes to this policy will be published at https://epictango.hiveagent.com.br/en/privacy/ with a new update date. Significant changes will be announced inside the app.
