Decks Privacy Policy
- You can play Decks without an account. We never ask for your name, email or phone number.
- Your settings and the decks you create stay on your phone.
- Anonymous usage statistics are sent only if you agree, and you can turn them off anytime in Settings.
- Payments are handled entirely by Google Play. We never see your card details.
- We do not sell your data, show ads, or use advertising IDs.
1. Who we are
Decks is published by [LEGAL NAME OF PERSON OR BUSINESS] ("we", "us"), [COUNTRY / POSTAL ADDRESS]. For any privacy question or request, email rubysoftwarestudio@gmail.com.
2. Information that stays on your device
The following is stored only in the app's private storage on your phone. We cannot see it:
- Your settings (sound, vibration, theme, text size, content preferences, whether you have confirmed you are 18 or older).
- Decks and cards you create.
- Which cards you have already played, so the app can show new cards first.
- Team and player names you type for a game. These are kept only while that game is running.
Uninstalling the app deletes all of this. If Android's own device backup is turned on, your settings and custom decks may be included in your personal Google backup. Your purchases are not.
3. Anonymous usage statistics (only with your permission)
The app asks once whether you want to share anonymous usage statistics. If you say yes, we use Google Analytics for Firebase (provided by Google LLC) to learn how the app is used, for example which cards are skipped most so we can rewrite them. You can change your answer anytime in Settings > Share anonymous stats.
If you agree, the following is collected:
| What | Examples |
|---|---|
| App activity | Game started or finished, deck viewed, card played or skipped (by deck and card ID), purchase screen viewed |
| App and device info | App version, device model, Android version, language, screen size |
| Approximate region | Country or region, which Google derives from your IP address. Google Analytics does not store IP addresses. |
| App instance ID | A random identifier created when the app is installed. It resets if you reinstall the app or clear its data. |
We do not collect your advertising ID, precise location, contacts, photos, or anything you type: the prompts on your custom cards, deck names and player names are never sent. We have turned off Google's ad personalisation and ad-related data sharing. Analytics data is kept for [2 / 14] months and then deleted automatically. Google's privacy policy: policies.google.com/privacy.
If you say no, or never answer, no analytics data is sent.
4. Purchases
Deck purchases and Premium subscriptions are processed by Google Play under Google's terms and privacy policy. We never receive or store your payment card details. To unlock what you bought, the app receives a purchase confirmation from Google Play: the product, the order ID and a purchase token. To protect against fraud, this confirmation may be sent to our secure server, hosted on Google Firebase or Google Cloud. There it is checked with Google and stored only for as long as needed to confirm your purchase or subscription. "Restore purchases" works through your Google Play account. You do not need a Decks account.
Google Play also shares purchase and subscription revenue figures with our Google Analytics reports, so we can see which decks and plans people choose. This comes from Google Play, not from your phone, and never includes your payment details.
5. Adult content and children
Decks is not directed at children under 13, and we do not knowingly collect personal information from children. Adult (18+) decks are hidden by default and shown only after the user confirms they are 18 or older. If you believe a child has provided us with personal information, email us and we will delete it.
6. How we use information
- To run the app and unlock purchases.
- To improve the cards and the app, using aggregated, anonymous statistics (only with consent).
- To answer support emails you send us.
We do not sell or rent personal information. We do not use it for advertising. We share it only with the service providers named above (Google), who process it for us, or when the law requires it.
7. Support emails
If you email us, we receive your email address and whatever you write, such as a problem description and device details. We use it only to reply, and delete it within [12] months after your issue is resolved.
8. Your choices and rights
Depending on where you live (for example under the GDPR in the EU and UK, or the CCPA/CPRA in California), you may have the right to access, correct, delete or object to the processing of your personal information, and to withdraw consent at any time.
- Turn off analytics: Settings > Share anonymous stats.
- Delete local data: uninstall the app, or clear its storage in Android settings.
- Delete your data: follow the steps on our data deletion page.
- Other requests: email rubysoftwarestudio@gmail.com. Because we do not collect your name or email in the app, we may ask you for your app instance ID, which you can find in Settings, or your Google Play order ID so we can find your data. We respond within 30 days.
You also have the right to complain to your local data protection authority.
Legal bases (EU/UK): consent for analytics; performance of a contract for purchases; legitimate interests for answering support requests and preventing fraud.
9. Security
Data on your phone is kept in the app's private storage, which other apps cannot read. Data sent to Google is encrypted in transit (HTTPS). No method of storage or transmission is completely secure, but we limit what we collect to keep risk low.
10. International transfers
Google may process data in the United States and other countries. Where required, transfers rely on safeguards such as the European Commission's Standard Contractual Clauses.
11. Changes to this policy
If we change this policy, we will update the effective date above. If the changes are significant, for example if we start collecting new kinds of data, we will tell you in the app before they take effect.
