Terms of Use

By using Casvia you agree to these simple terms. Last updated: September 2026.

1. What Casvia is

Casvia provides free educational calculators and general information about UK savings, ISAs, tax, property and retirement. It is a tool for understanding, not a source of personal financial, tax or investment advice.

2. No advice, no guarantee

All results are hypothetical estimates based on the assumptions you enter. They are not forecasts, offers, or recommendations, and they are not a guarantee of future returns. Always check the latest official guidance (e.g. GOV.UK, HMRC) before making financial decisions, and consider consulting a regulated adviser for personal circumstances.

3. Acceptable use

You may use the calculators freely for personal or educational purposes. Do not use the site in any way that is unlawful, that attempts to disrupt it, or that misrepresents the tools as professional advice.

4. Availability & accuracy

We aim for accuracy but the site is provided “as is” without warranties of any kind. UK rules change; figures may become out of date. We may update, change or remove tools at any time without notice.

5. Privacy

Your use of the calculators is covered by our Privacy Policy. We do not collect or store your inputs.

6. Intellectual property

The content, design and code on Casvia are provided for your personal use. Please don't republish our content or assets as your own.

7. Changes to these terms

We may update these terms from time to time. Continued use of the site after changes means you accept the updated terms.
