Privacy Policy

Effective date: October 11, 2026.

Usefulia provides browser-based utilities for documents, images, calculations, text, domains and related everyday tasks. This policy explains what information may be processed when you use the website.

1. Files and tool input

Many Usefulia tools are designed to process files or text directly in your browser when the task can be performed locally. For server-backed features, only the information necessary to perform the requested operation is transmitted to the relevant infrastructure. Usefulia does not claim ownership of user-submitted content.

2. Technical and usage information

We may process page views, tool runs, success or error events, browser and device information, referrer information, approximate location derived from infrastructure headers, and network identifiers for analytics, security and abuse prevention. Full IP addresses in protected internal visitor logs are retained for up to four days and are then removed from the active analytics log.

3. Analytics and advertising

Usefulia may use analytics and advertising services. On the main international site, Google technologies may be used for advertising and measurement. The Russian-language site may use Yandex advertising services. These providers can use cookies or similar technologies according to their own policies and applicable consent requirements.

4. Contact messages

If you use the contact form, we process the name you choose to provide, your reply email, the selected topic and your message. A privacy-preserving hash of the network address may be used for rate limiting and abuse prevention. Contact messages are retained only as reasonably necessary to respond, maintain records and prevent abuse.

5. Service providers

Usefulia may rely on hosting, deployment, storage, analytics, advertising and security providers. Information required for a feature can therefore be processed by infrastructure providers that help operate the website.

6. Cookies and similar technologies

For details about necessary, analytics and advertising technologies, see the Cookie Policy. Browser settings can also be used to block or delete cookies, although doing so can affect some functions.

7. Your choices and rights

Depending on applicable law, you may have rights concerning access, correction, deletion, restriction or objection to processing. Use the contact page for a privacy request and provide enough information for us to understand the request without including unnecessary sensitive data.

8. Security and retention

We use reasonable technical and organizational measures intended to protect the service and reduce unauthorized access or misuse. No internet service can guarantee absolute security. Operational data is retained only for periods reasonably necessary for service operation, security, troubleshooting, legal compliance and legitimate record keeping.

9. Children

Usefulia is not designed to knowingly collect personal information from children where parental consent would be legally required.

10. Changes

We may update this policy when the service or legal requirements change. The current version and effective date are published on this page.
