GDPR
This notice applies if you are located in the United Kingdom, the European Union, or the European Economic Area. It supplements our Privacy Policy and explains your rights under the UK General Data Protection Regulation (UK GDPR), the Data Protection Act 2018, and the EU GDPR.
1. Who is the data controller?
Calculeaf is operated by an individual sole operator based in the United Kingdom, who is the data controller responsible for your personal data. You can reach us at calculeaf01@gmail.com.

3. Your rights
Under the UK GDPR and EU GDPR you have the right to:
- Access — request a copy of the personal data we hold about you.
- Rectification — ask us to correct inaccurate or incomplete data.
- Erasure — ask us to delete your data ("right to be forgotten").
- Restriction — ask us to limit how we process your data.
- Portability — receive your data in a portable, machine-readable format.
- Object — object to processing based on legitimate interests, and to direct marketing at any time.
- Withdraw consent — where we rely on consent, withdraw it at any time without affecting prior processing.
- Not be subject to automated decision-making that produces legal or similarly significant effects. We do not carry out such decision-making.
4. How to exercise your rights
Email calculeaf01@gmail.com with your request. We will respond within one month, as required by law. There is normally no charge, and we may need to verify your identity before acting on a request.
5. International data transfers
Some of our service providers (for example, Google) may process your data outside the UK and EEA. Where this occurs, we rely on appropriate safeguards such as the UK International Data Transfer Agreement, the EU Standard Contractual Clauses, or an adequacy decision, so that your data continues to receive an equivalent level of protection.
6. Data retention
We keep your account data and worksheets for as long as your account is active. When you delete your account, we delete or anonymise the associated personal data, except where we must retain it to meet a legal obligation. Analytics and log data are retained for a limited period.
7. Right to complain
If you believe we have not handled your personal data properly, you have the right to lodge a complaint with a supervisory authority. In the UK this is the Information Commissioner's Office (ICO), ico.org.uk. If you are in the EU/EEA, you may complain to your local data-protection authority.
