Client funds are held in a Barclays Client Account

Where we are required to segregate your funds, we place them into a segregated account (known as a ‘safeguarding account’) at Barclays Bank PLC.

As an FCA Authorised Payment Institution, we are not covered by the Financial Services Compensation Scheme. Instead, where we have segregated your funds in a safeguarding account, it means those funds would be separated from our other assets in the event of our insolvency and used to repay you and other clients.

Barclays Bank PLC provides us with safeguarding account(s), but does not monitor the funds we place on the safeguarding account or how we operate these accounts. As an FCA Authorised Payment Institution it is our responsibility to segregate funds.

Data protection

We are registered with the Information Commissioner’s Office (No. PZ8997024) under the Data Protection Act 2018 and fully compliant with General Data Protection Regulation (GDPR).

We understand that the privacy of your personal information is important. We will keep your data safe and not share it with anyone else to be used for marketing, promotional or other purposes.

Any information you provide will be used in accordance with our privacy policy which you can find here

Online security

Our clients’ online security is our top priority. The RationalFX online platform uses some of the latest security software to ensure that your money transfers are safe and secure.

The server uses the secure web site protocol called SSL.

Your data is transmitted in a secure way and all password data is encrypted.

If you make a card payment, the card security code or internet password (e.g. Verified by Visa) are not visible to RationalFX and are always hidden and encrypted.
