3.0 Disclosures of your personal data

We may share your personal data where necessary with the parties set out below for the purposes set out in the table above.

3.1 Business Transactions

If the Company is involved in a merger, acquisition or asset sale, Your Personal Data may be transferred. Alternatively, we may seek to acquire other businesses or merge with them. We will provide notice before Your Personal Data is transferred and becomes subject to a different Privacy Policy.

Comply with a legal obligation
Protect and defend the rights or property of the Company
Prevent or investigate possible wrongdoing in connection with the Service
Protect the personal safety of Users of the Service or the public
Protect against legal liability

4.0 International transfers

We may transfer your personal data to service providers that carry out certain functions on our behalf. This may involve transferring personal data outside the UK or EEA to countries which have laws that do not provide the same level of data protection as the UK or EU law.

Whenever we transfer your personal data out of the UK or EEA to service providers, we ensure a similar degree of protection is afforded to it by ensuring that the following safeguards are in place: ● We will only transfer your personal data to countries that have been deemed by the UK or the EU to provide an adequate level of protection for personal data; or ● We may use specific standard contractual terms approved for use in the UK and/or EEA which give the transferred personal data the same protection as it has in the UK or EEA, or another transfer mechanism which has been approved by the relevant regulator in the UK and/or the EEA.

5.0 Data security

We have put in place appropriate security measures to prevent your personal data from being accidentally lost, used or accessed in an unauthorised way, altered or disclosed. In addition, we limit access to your personal data to those employees, agents, contractors and other third parties who have a business need to know. They will only process your personal data on our instructions and they are subject to a duty of confidentiality.

6.0 Data retention

How long will you use my personal data for?

Your information is securely stored. OnionAI will retain Your Personal Data only for as long as is necessary for the purposes set out in this Privacy Notice.

We will retain and use Your Personal Data to the extent necessary to comply with our legal obligations (for example, if we are required to retain your data to comply with applicable laws), resolve disputes, and enforce our legal agreements and policies. The Company will also retain Usage Data for internal analysis purposes. Usage Data is generally retained for a shorter period of time, except when this data is used to strengthen the security or to improve the functionality of Our Service, or We are legally obligated to retain this data for longer time periods.

To determine the appropriate retention period for personal data, we consider the amount, nature and sensitivity of the personal data, the potential risk of harm from unauthorised use or disclosure of your personal data, the purposes for which we process your personal data and whether we can achieve those purposes through other means, and the applicable legal, regulatory, tax, accounting or other requirements. In some circumstances we will anonymise your personal data (so that it can no longer be associated with you) for research or statistical purposes, in which case we may use this information indefinitely without further notice to you.

7.0 Protecting your sensitive data

OnionAI follows the information security values of

confidentiality - making sure your information is always kept secret and private;
integrity - we ensure the completeness, consistency, and accuracy of the data over its lifecycle; and
availability - we ensure the right information is available to the right person at the right time we use the following techniques and best practices to protect your sensitive data:

7.1 People

Training - All staff receive regular appropriate training on data protection and security and their related duties to ensuring your personal data is secure;
Minimised access: your personal data, including Health Data, can only be accessed on a strictly needs to know basis by our admin staff, or customer support as and when necessary, specifically as relates to your particular request for support;
Security expertise: To design and operate our platform, we utilise qualified security professionals with recognised experience and certifications in technical security architecture as well as governance, risk, and compliance.

7.2 Cyber resiliency, business continuity, and disaster recovery

We utilise the most secure and resilient infrastructure from Google Cloud Platform (GCP) which ensures servers are always patched and up to date.
Automated tests are performed internally across the codebase on every commit.
In addition, we commit to undertaking annual third-party security audits with certified security auditors including web, desktop and mobile application penetration tests to ensure comprehensive coverage.

7.3 Technology

We adopt principles of Secure by Design, including:

Architecture in line with industry standards.
This includes role based access controls.
Our APIs utilise authentication and authorisation to ensure data minimisation and prevent unauthorised access to data.

We use encryption in all of the following scenarios:

In transit using modern protocols (TLS only) and secure ciphers (both internally within the VPC and externally with users & applications)
At rest using AES-256 encryption

Data centres:

We host data in multiple availability zones/regions in order to maximise availability. All production environments are located within the UK and EEA.
Where possible, deploy a High Availability (HA) architecture to ensure resilience with automated failover to provide uninterrupted service.

Development, security & operations:

We operate a mature secure software development life cycle (SDLC), which includes but is not limited to:

Separation of keys for each environment and robust key management processes
Regular dependency and package management audits and remediation
Logical separation of production and development environments including isolated databases
Static code testing to ensure code is free from known vulnerabilities
Dynamic code testing to ensure applications do not expose vulnerabilities
Manual security testing (annual penetration test)

8.0 Your legal rights

You have a number of rights under data protection laws in relation to your personal data. You have the right to:

Request access to your personal data (commonly known as a "subject access request"). This enables you to receive a copy of the personal data we hold about you and to check that we are lawfully processing it.
Request correction of the personal data that we hold about you. This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.
Request erasure of your personal data in certain circumstances. This enables you to ask us to delete or remove personal data where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove your personal data where you have successfully exercised your right to object to processing (see below), where we may have processed your information unlawfully or where we are required to erase your personal data to comply with local law. Note, however, that we may not always be able to comply with your request of erasure for specific legal reasons which will be notified to you, if applicable, at the time of your request.
Object to processing of your personal data where we are relying on a legitimate interest (or those of a third party) as the legal basis for that particular use of your data (including carrying out profiling based on our legitimate interests). In some cases, we may demonstrate that we have compelling legitimate grounds to process your information which override your right to object.
You also have the absolute right to object any time to the processing of your personal data for direct marketing purposes.
Request the transfer of your personal data to you or to a third party. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. Note that this right only applies to automated information which you initially provided consent for us to use or where we used the information to perform a contract with you.
Withdraw consent at any time where we are relying on consent to process your personal data. However, this will not affect the lawfulness of any processing carried out before you withdraw your consent. If you withdraw your consent, we may not be able to provide certain products or services to you. We will advise you if this is the case at the time you withdraw your consent.
Request restriction of processing of your personal data. This enables you to ask us to suspend the processing of your personal data in one of the following scenarios:
- If you want us to establish the data's accuracy;
- Where our use of the data is unlawful but you do not want us to erase it;
- Where you need us to hold the data even if we no longer require it as you need it to establish, exercise or defend legal claims; or ○ You have objected to our use of your data but we need to verify whether we have overriding legitimate grounds to use it.

8.1

No fee usually required

You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request is clearly unfounded, repetitive or excessive. Alternatively, we could refuse to comply with your request in these circumstances.

8.2

What we may need from you

We may need to request specific information from you to help us confirm your identity and ensure your right to access your personal data (or to exercise any of your other rights). This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request to speed up our response.

8.3 Time limit to respond

We try to respond to all legitimate requests within one month. Occasionally it could take us longer than a month if your request is particularly complex or you have made a number of requests. In this case, we will notify you and keep you updated.
