Terms of Use

1. Service

CalcDuo provides calculators, converters, file-processing utilities and informational tools. The core service is free and does not require an account. Features may be added, changed or removed over time.

2. Acceptable use

• Use the service lawfully and only for content you own or are authorized to process.
• Do not upload malware, attack or overload the service, bypass limits, or interfere with other users.
• Do not submit illegal, confidential or rights-infringing third-party content.

3. Results are not professional advice

Results are provided for information and preliminary calculation. Financial, tax, health, legal, education and similar outputs are not an official decision, quote, diagnosis or professional advice. Check current official sources and a qualified professional when appropriate.

Inputs, rates, source data, rounding and third-party services can affect results. Do not make an important decision solely from a tool output.

4. Files and user content

Upload only files you are entitled to use and convert. You are responsible for backups and for validating output. Conversion jobs are temporary and the service is not permanent file storage.

5. Intellectual property

The service design, software, editorial content and brands belong to their respective owners. You may use your own results, but may not copy or republish service assets or create brand confusion without permission.

6. Third parties and availability

Some tools depend on third-party data or infrastructure. Their accuracy, availability and terms are controlled by those providers. The service may be interrupted for maintenance, security or technical reasons.

7. Disclaimer and liability

To the extent permitted by law, the service is provided as available without a guarantee of uninterrupted or error-free operation. We are not responsible for indirect losses caused by incorrect input, interpretation, data loss or third-party interruption. Mandatory consumer rights remain unaffected.

8. Changes and contact

Terms may be updated when the service or law changes. The current text applies from its published date. Questions can be sent through the developer contact in the applicable app-store listing or a current service contact channel.
