Privacy
policy
English translation of the policy dated 12 September 2026. Translation published on 23 September 2026.
This policy describes the data used in One Bullet to save progress and provide advertising, purchases, analytics and support. It covers the version using Yandex Mobile Ads, AppMetrica and payments through RuStore.
1. Developer and contact details
The developer and the operator of data received directly by the developer is Individual Entrepreneur Andrey Viktorovich Nazarov (ИП Назаров Андрей Викторович), publishing as SoftLampa. For questions about the game or data processing, contact info@softlampa.ru.
Android application identifier: games.onebullet.puzzle.
2. Progress and settings
The game saves completed levels, records, sound and interface settings, game counters and information needed to apply a purchased ad-removal entitlement on your device. These are used to continue your game and retain your preferences. The game has no separate account registration and the developer does not operate a server for storing game progress.
Local data stays on your device until you or the system delete it. You can delete it in Android settings: One Bullet → Storage → Clear data. This resets progress and settings. System backups depend on your Android settings.
3. Yandex advertising
The game uses the Yandex Mobile Ads SDK, which connects to Yandex services to load and display ads. Where the necessary permissions are available, the SDK may process the device advertising identifier. Processing by Yandex is described in the Yandex privacy policy.
Location sharing with the advertising SDK is not enabled in this project. The game does not request Android permission for precise or approximate location. Information about SDK data collection is available in Yandex documentation.
The purchase to remove automatic ads disables automatic ads between levels. Ads for in-game help remain optional. Removing automatic ads does not disable the advertising SDK entirely.
4. RuStore purchases
Payments and purchase records are handled by the RuStore Pay SDK and the payment services for the selected payment method. The game requests product and price information, a purchase identifier and purchase status to confirm payment and restore the purchased feature.
The developer does not receive your bank card number, card security code or banking app password through the game code. Account and payment data are processed under the RuStore user privacy policy and the terms of the selected payment service.
Deleting local game data does not cancel a purchase. A confirmed purchase can be restored through the same RuStore account. The store may retain purchase records after the game is removed.
5. Analytics and errors
The game uses Yandex AppMetrica to assess game quality, identify difficult levels and analyse crashes and monetisation results. Events sent to the service include app launches and game sessions, level starts and completions, attempt counts, completion time, hint use, ads and purchases. Confirmed purchase events include the product identifier, amount, currency and quantity; test payments are not recorded as revenue.
The SDK also processes technical information about the app and device, installation identifiers, network connection information and crash reports. Location and advertising identifier tracking are disabled in the AppMetrica configuration. The game code does not send your name, email address, bank card details, passwords or payment tokens to analytics. Analytics data is not a cloud backup of game progress.
Processing by the service is described in the Yandex privacy policy and AppMetrica data security documentation. You may send data-processing requests to the developer using the contact address below.
6. Support, retention and requests
When you contact info@softlampa.ru, the developer receives your sender address, message and any attachments you choose to provide. These are used to respond, resolve the issue and handle data-processing requests.
Support data is processed only to the extent and for the time needed to resolve the request and meet applicable legal requirements. After these purposes have been met, the data is deleted unless there is a lawful reason to retain it.
You may request information about the processing of your data, ask for correction or deletion, or withdraw previously given consent where processing is based on consent. Send your request to the email address above. Requests concerning data independently processed by Yandex or RuStore may also be sent to those services using the contacts in their policies.
Do not send passwords, verification codes or card security codes to support. The developer limits use of the information received to the purposes of your request.
7. Changes to this policy
This document is updated when the game's features or connected services change. The current version is published on this page, with links provided in the game and its store listing.
