Data protection officer
We have not appointed a data protection officer. The contact above handles questions and requests about personal information.
Information we collect
We collect information in these ways:
- Information you give us, such as your name, email address and the content of your messages.
- Information collected automatically when you use the site, such as your IP address, browser type, device, pages viewed and the time of your visit, kept in server logs for security and troubleshooting.
Your account
If you create an account we collect your name, email address and a credential used to sign in, and the activity linked to the account, such as what you do in the service and your saved preferences. Accounts are Praecise accounts: you sign in at accounts.praecise.com, which PRAECISE LTD also operates.
Payments
Payments are handled by a payment provider. We do not receive or store your full card number; we receive confirmation of the payment, the amount and the last digits of the card.
When we process information for our customers
When a business uses Rivier, we process the personal data of that business's own customers, leads and visitors on the business's behalf. The business decides what is put in and why; our terms with the business are at https://rivier.ai/dpa. If you are one of those people, ask the business first about your information; we will help it answer you.
Files you upload
If you upload files or images to the site we store them and the details attached to them, and use them only to provide the feature you used.
AI assistant
Parts of our service use an artificial intelligence assistant. You are told when you are talking to it, and it is not a person.
What you type to the assistant is processed by an AI service provider acting for us to produce an answer, and we keep the conversation as part of the workspace's records, to give you support. Please do not include sensitive information such as health details or payment card numbers. Answers can be wrong; where a decision matters, ask us to confirm it with a person.

Keeping it safe
We use technical and organisational measures to protect personal information, including access controls, encryption of data in transit and a record of actions taken. No method of transmission or storage is completely secure, so we cannot guarantee absolute security. If a breach affects you, we will tell you and the authorities as the law requires.
Children
Our services are not aimed at children, and we do not knowingly collect personal information from anyone under 18. If you believe a child has given us information, tell us (contact@praecise.com) and we will delete it.
Changes to this policy
We update this policy when what we do changes. The date at the top shows when it last changed, and for significant changes we will tell you in a way that fits, such as a notice on the site or an email.

Complaints (United Kingdom)

You have the right to ask us for a copy of your personal information; to correct it; to have it erased; to restrict or object to our use of it; to receive it in a portable format; and to withdraw consent at any time where we rely on consent, without affecting what we did before.
To use a right: email contact@praecise.com, or write to PRAECISE LTD, 86-90 Paul Street, London, England, EC2A 4NE. We may need to check who you are first. We answer within one month; if a request is complex or we have many, we may extend this by up to two further months and will tell you why.
Complaints (European Union)
You may complain to the data protection authority of the country where you live, work or where you think the problem happened.
Transfers outside Europe and the UK
Some of the service providers we use may process information in countries outside the European Economic Area or the United Kingdom. Where that happens we use a safeguard the law recognises, such as an adequacy decision or standard contractual clauses. Ask us which safeguard applies to a provider.
