One Stroke!

One Stroke! / Jednym ruchem!

Privacy policy

Effective: 19 October 2026

1. Who is responsible?

The controller is Bartłomiej Pasiut, trading as Bartłomiej Pasiut Software Solutions, ul. Papierni Prądnickich 78/35, 31-234 Kraków, Poland, tax ID (NIP) 7343619168. Contact: mobileappsfirst@gmail.com. This policy covers One Stroke! (Polish name: Jednym ruchem!), Android package com.mobileappsfirst.onestroke, and this website.

2. Game data on your device

The game does not require an account. Progress, language, current puzzle and unlocked hints are stored locally in the app’s private storage. We do not operate a server receiving your puzzle history or a cloud-save service. Clearing app data or uninstalling removes local progress and preferences. A verified Premium purchase receipt may also be cached locally to remember access while offline.

3. Advertisements and rewarded hints

The app uses Google AdMob and Google’s User Messaging Platform. Depending on consent and device settings, Google may process IP addresses and approximate location, advertising or other device identifiers, ad interactions, and diagnostic data to deliver and measure ads and prevent fraud. We do not request precise GPS location. Interstitial ads may appear between puzzles. Rewarded ads are optional: choosing one can unlock a hint after the reward condition is met. Test versions may use test ads; these can still involve technical data processing.

4. Privacy choices

Where required, including the EEA, UK and Switzerland, a Google consent message is shown before requesting ads. You can revisit available choices through the app’s privacy options when this option is required. Withdrawing consent does not affect earlier lawful processing. Depending on your choices, ads or rewarded hints may be limited or unavailable; the core puzzles remain playable. Android settings also provide advertising-identifier controls. Consent is the legal basis for optional advertising/device access where required.

5. Premium purchases

When enabled, Premium is a one-time purchase through Google Play that disables advertising in this app and provides hints without watching ads. Google Play handles payment; we do not receive card details or your Google password. The app processes the product ID, purchase status, purchase token and signed receipt to verify and acknowledge purchases and restore access with the same Google Play account. A verified receipt can be stored on the device. Uninstalling does not cancel purchase ownership. Test or unpublished versions may not offer purchases. Premium stops app ad requests and displays, but Google Play still processes purchases and support services still process information you send.

6. Support and this website

If you email us, we process your email address and the information you choose to send to answer your request. Avoid sending passwords, card details or unnecessary sensitive information. This website uses Firebase Hosting, operated by Google, which processes IP addresses for delivery, security, abuse prevention and usage analysis; Firebase states that Hosting retains IP addresses for a few months. We do not add analytics scripts, advertising tags, external fonts or tracking cookies to this site. The game does not integrate standalone Firebase Analytics or Crashlytics.

7. Purposes and legal bases

Where GDPR applies, processing necessary to deliver requested game and purchase functionality is based on performance of a contract (Article 6(1)(b)); optional consent-based processing uses Article 6(1)(a). Our legitimate interests in responding to general correspondence, securing services and handling claims use Article 6(1)(f), subject to your rights. Applicable legal record-keeping obligations use Article 6(1)(c). Google’s own processing is described in its policies and any consent information shown in the app.

8. Recipients and international processing

Relevant service providers are Google AdMob, User Messaging Platform, Google Play, Firebase Hosting and our email provider (Gmail). Any advertising providers available through the consent message are identified there. Information may be disclosed where legally required. Google services can process information outside your country, including in the United States. Depending on the service and location, safeguards may include adequacy decisions and standard contractual clauses. Google explains its safeguards in its data transfer frameworks.

9. Retention and security

Local game data remains until you clear it or uninstall the app; cached purchase information may also be updated when purchase status changes. Google maintains its own purchase and advertising records under its policies. Support correspondence is retained for as long as needed to resolve the request and any applicable legal obligations or claims. Hosting IP retention is described above. The app uses Android private storage and Google service connections use encrypted transport. No system can guarantee absolute security.

10. Your rights and deletion

Where applicable, you may request access, correction, deletion, restriction, portability, or object to processing, and withdraw consent. Contact the email above; we may need sufficient information to identify the request. We respond within applicable legal time limits. You can complain to the Polish supervisory authority, UODO, or your local data protection authority. To remove local game data, use Android Settings → Apps → One Stroke! → Storage → Clear data, or uninstall. This does not erase Google’s independent records. No developer account is created, so there is no account to delete. For Google-held information, use Google’s privacy controls or contact Google.

11. Children and updates

If you believe a child has provided personal information to us through support, contact us so we can review and address it. We may update this policy when features, services or requirements change. The current effective date appears above.
