Privacy Notice
Last updated: January 2026
Outbuilding Planner respects your privacy. This Privacy Notice explains what information we collect, how we use it, and the choices you have when using our website.
This website is designed to minimise the collection of personal data. No user accounts are used and no personal information is required to use the calculator.
1. Who We Are
Outbuilding Planner is a UK-based DIY planning tool that helps users estimate materials for timber-frame garden buildings. If you have any questions about this Privacy Notice or how your data is handled, you can contact us using the details provided on our Contact page.
2. Information We Collect
a) Calculator Data (Not Personal)
When you use the Outbuilding Planner calculator, calculations are performed in your browser. We do not store or retain building dimensions, configuration options, or calculation results. This data is used only to provide the calculator output during your active session.
b) Technical and Hosting Data
Like most websites, limited technical information may be processed automatically by our hosting and infrastructure providers, such as:
- IP address
- Browser and device type
- Date and time of access
This information is used only to operate, maintain, and secure the website and is not used to identify you personally.
3. Cookies and Local Storage
Outbuilding Planner may use essential browser storage (such as sessionStorage or localStorage)
to improve usability – for example, temporarily preserving calculator inputs while navigating the site.
We do not use cookies or storage for advertising, analytics, or behavioural tracking.
4. How We Use Information
We use the limited information described above only to:
- Provide and operate the calculator
- Maintain website performance and security
We do not use data for marketing, profiling, or tracking.
5. Sharing of Information
We do not sell or share personal data. Limited technical data may be processed by website hosting providers. Such providers act under appropriate data protection obligations.
6. Your Rights
Under UK data protection law, you have the right to request information about any personal data we hold about you, and to request correction or deletion of personal data where applicable.
Because the calculator does not collect or store personal data, these rights will typically apply only to any communications you initiate with us.
7. Changes to This Notice
We may update this Privacy Notice from time to time to reflect changes to the website or how data is handled. The latest version will always be available on this page.
8. Contact
If you have any questions about privacy or data protection at Outbuilding Planner, please contact us using the details provided on the Contact page.
