Privacy Policy

Last updated: October 8, 2026 · Shared principles and app-specific policies

This policy has two parts. Part A applies to every 1Buck App on every platform. Part B links to each app's own policy, which lists what that app accesses on your device and why.

Part A. All 1Buck Apps

1. Who we are

1Buck Apps (1Cleaner, 1Scanner and the apps that follow) are developed by Antosha (Anton Trantin, a private individual and independent developer, publishing as Antosha Apps; "we", "us"). Contact: [email protected].

2. Data we collect

The apps do not require a developer account and do not send developer analytics to us. Optional AI features in 1Polish and 1Chinese process the content you submit to them and keep technical authentication, purchase and credit records without that content (section 3). Third-party platform services, purchases and support are described in each app’s own policy. In particular, Google SDKs used by 1Scanner for Android collect technical diagnostics and usage information; its Android policy explains this separately from on-device documents. Store privacy labels are specific to each app and platform; this shared page does not declare one label for the entire line.

3. AI features

Apps with AI features may send your AI inputs (text you type, the context needed for the task and voice recordings) through our server to AI providers such as OpenAI, Google (Gemini), Anthropic, DeepSeek, Moonshot AI (Kimi), Alibaba Cloud (Qwen) and ElevenLabs. Each app's own policy names the exact features and providers it uses.

• Protective proxy. Requests run on our access keys; the apps contain no provider keys. Our server forwards the request and returns the answer. It does not log the content of your texts, recordings, transcripts or AI answers and does not save it in its database; the only copy is the encrypted retry cache below.
• Technical records without content. For credit accounting the server keeps: a one-way hash of the app's random install id that keys the credit wallet, the credit balance, the request id and the provider's own request id, a one-way hash of the request, the operation type, model, provider, token (or second or character) counts, cost and time. Purchase records needed to grant credits (for example a one-way hash of the App Store transaction id with the product and period dates) are described in each app's policy.
• Retry cache. A completed AI result (for example a reply, a transcript or generated audio) is kept encrypted in memory (Redis) for up to 15 minutes, so a retry after a dropped connection returns it without charging twice; then it is deleted. An encrypted copy can briefly remain in the server's periodic memory snapshot until it is overwritten.
• Logs. Our application's error logs contain only error codes and technical event names. Web server and network logs can contain the IP address, time and requested path, without content, and are kept for a limited time. Requests, including their content, pass through Cloudflare, our network provider, on the way to our server.
• Providers. AI providers process the data under their own API terms and privacy policies, linked above, which also govern how long they keep it. We do not sell AI content, use it for advertising or use it to train AI models.

4. On-device processing and permissions

Each app asks for a system permission when you use a feature that needs it. Local tasks run on your device; optional network features, including AI features, transmit the information needed for that feature as described in the app-specific policy. You can refuse a permission; features that do not need it keep working. The exact permissions for each app are listed in its own policy (Part B).

5. Purchases

Purchases are processed by the store you buy from. We do not receive your payment-card details. Apps may use purchase status and transaction records to verify access or grant AI credits.

• iPhone and iPad: processed by Apple and verified on device with StoreKit; to grant AI credits in 1Chinese, the App Store signed transaction is also verified once on our server. See Apple's Privacy Policy.
• Android: processed by Google Play. Verification can run on-device or, for 1Polish AI credits, through our server as described in its app-specific policy. See Google's Privacy Policy.

6. Support emails

If you email us, we receive your email address and message and use them only to answer you. We do not add you to marketing lists.

7. Children

1Cleaner and 1Scanner are not directed to children under 13. Intended audiences and any app-specific limits are described in each app’s own policy.

8. Your choices

You can change or revoke any permission at any time in your device's Settings (iOS Settings or Android Settings). You can delete an app's data by deleting the app; exceptions are described in each app's own policy.

9. Changes

If this policy changes, we will update this page and the date above. Material changes will also be noted in the app's release notes.

10. Contact

Questions? Write to [email protected].

Part B. Each app's own policy

Every app has its own complete policy with the permissions it uses and why:

• 1Cleaner for iPhone and iPad
• 1Cleaner for Android
• 1Scanner for iPhone and iPad
• 1Scanner for Android (including Google ML Kit and Play services)
• 1Polish for Android (including optional AI text and voice features)
• 1Chinese for iPhone (including optional AI text and voice features; на русском)

If an app's own policy and this page ever differ, the app's own policy applies to that app.
