Tangram Easy

Privacy Policy

This policy covers the Tangram Easy website and forms, the main Tangram Easy Android app and the separate Tangram Easy Kids edition. The products contain no advertising, and personal data is not sold.

Who is responsible for your data

The data controller is Pavel Fibik. Tangram Easy is an original project operated in Poland by an individual carrying out unregistered activity (działalność nierejestrowana) under Polish law.

1. Website and forms

Information you provide

  • Google Group testing access: the website no longer collects tester emails through a registration form. When you join the Tangram Easy Testers Google Group, Google processes your Google Account and membership information, and the group owner may see your member email to manage closed-test access and essential testing communication.
  • Wooden puzzle enquiry: your name or nickname, email and an optional phone number or Telegram username.
  • Account-deletion form: your reply email, optional nickname, names of published figures, Google Play order ID and other information you choose to provide so the account can be identified.
  • Messages: information you choose to include when contacting the developer.

This information is used only to manage Google Group and Google Play testing access, provide essential testing communication, respond to you, discuss a possible wooden puzzle order, or identify and process an account-deletion request. The legal bases are taking steps at your request, performing an agreement where one is concluded, complying with legal duties, and legitimate interests in operating, securing and improving the project.

Form and website providers

The remaining website forms are processed by Formspree. Formspree hosts its service on infrastructure in the United States and states that it relies on European Commission Standard Contractual Clauses for GDPR transfers. Closed-test membership is managed through Google Groups and Google Play under the Google Privacy Policy. Website hosting and Google Fonts may also receive ordinary technical request data such as IP address, browser type and request time.

The website does not use advertising or behavioral analytics. Puzzle completion and interface preferences may be stored locally in your browser so the interactive guide can remember them. This local data is not submitted through website forms.

2. Tangram Easy Android app

Information stored on your device

Puzzle results, settings, saved collections and other gameplay preferences are primarily stored on your device. You can remove them by clearing the app data or uninstalling the app.

The optional camera permission is used only when you choose to scan a Tangram Easy QR code. The image is processed on the device for code recognition; Tangram Easy does not upload or save camera images.

Anonymous account and community features

The main edition uses Firebase Authentication to create an anonymous account for online features. The app may process an anonymous user identifier, nickname, selected avatar, Premium entitlement, last-active time, community figures you publish, figure names and geometry, likes, downloads, reports, votes and moderation information.

Your nickname and published figures are visible to other players. Do not use your real name or include personal information in figure names if you do not want it to be public. The app performs an initial automated text check and lets users report public figures; reports and moderation records are used to protect the community and investigate misuse. Publication, licensing and moderation are described in the Terms of Use and Community Rules.

If you send feedback from the app, the message is stored with the app version, Android version and device model so the issue can be understood and the product improved.

Technical data and purchases

Firebase and Google may automatically process technical data required to provide and secure the service, including IP address, user agent, Firebase app and installation identifiers, anonymous user ID, requested cloud function, device language, country or approximate region, time zone, Android version, package name and, where applicable, a notification token. Tangram Easy does not request or collect precise GPS location.

Purchases are handled by Google Play Billing. For purchase verification, the app sends the product ID and Google Play purchase token to a protected Cloud Function. Tangram Easy does not receive complete payment-card or bank-account details.

Services used and purposes

The main edition uses Google services including Firebase Authentication, Cloud Firestore, Remote Config, Cloud Functions and Google Play Billing to provide accounts and community features, verify Premium access, deliver suitable configuration, prevent abuse and operate the service. Processing by these providers is described in the Firebase privacy and security information and Google Privacy Policy.

The app contains no advertising and does not sell personal data or use it for targeted advertising. The current build does not include Firebase Analytics or Firebase Crashlytics and does not use AI to process personal data.

Account and data deletion

You can start deletion in the app from Profile → Delete account. You can also use the public account and data deletion page if you no longer have access to the app. Because the account is anonymous, information that helps identify it may be required.

Deletion removes the anonymous authentication account, public profile and personal identifiers linked to it. A figure already published in the public gallery may remain under the licence in the Terms of Use and Community Rules after it is disconnected from the account and its author nickname is removed or replaced with a neutral label. Local data is removed separately by clearing app storage or uninstalling the app. Limited purchase-entitlement, transaction, security, fraud-prevention, report or moderation records may be retained only where needed to protect users, preserve an entitlement, meet a legal obligation or handle claims. Access is restricted, and retained records are deleted or de-identified when no longer needed.

3. Tangram Easy Kids edition

The Kids edition is a separate, simplified build. It does not provide accounts or community publishing and does not include Firebase Authentication, Firestore, Remote Config, Cloud Functions or Google Play Billing used by the main edition. Gameplay results and settings are stored locally on the device.

The Kids edition does not ask a child to provide a name, email address, precise location or profile information. It contains no advertising, analytics or cross-app tracking and does not request camera access. Google Play and the device platform may process download, security and technical diagnostic data under Google's own policies.

A parent or guardian can remove local data by clearing the app storage or uninstalling the app. If you believe a child has sent personal information through an external support channel, contact us so it can be reviewed and deleted where appropriate.

4. Sharing and international transfers

Data is shared only with the providers described above where needed for their services, when you choose to publish community content, or when disclosure is required by law or necessary to protect users and the service. Personal data is not sold. Google/Firebase and Formspree may process data outside the European Economic Area using their applicable transfer safeguards.

5. Retention and security

  • Google Group membership and the tester email visible to the group owner are kept while testing and associated access require them, until you leave the group, or until a valid deletion request unless a legal duty requires retention.
  • Enquiry, transaction and correspondence records are kept only as long as needed to handle the matter and meet applicable accounting, tax, consumer-law and claims obligations.
  • Main-app account and community data is kept while the anonymous account or published content remains active, subject to deletion and the limited exceptions described above.
  • Firebase may retain certain service logs and backups for limited periods under Google's documented retention practices.
  • Local website and app data remains on your device until you clear it or uninstall the app.

Access to project data is limited. Firebase supports encryption in transit and at rest for the services used. No internet transmission or storage system is completely secure.

6. Your rights

Depending on applicable law, you may request access, correction, deletion, restriction, portability or object to processing, and may withdraw consent where consent is the legal basis. You may also complain to the Polish data protection authority, the President of the Personal Data Protection Office (UODO). These rights may be limited where retention is required by law or needed to establish or defend legal claims.

7. Changes to this policy

This policy may be updated when the products, providers or legal requirements change. The new effective date will be shown at the top of this page.
