What we collect, and why.
This policy covers prevoresearch.com, operated from Singapore under the name Prevo. It is written to be read, and it describes what the site actually does today. Last updated 25 September 2026.
1. What we collect
Four kinds of data, all of them things you give us or create here. First, your account: the email address you sign in with and the display name you choose. Second, your research activity: the events you save, the collections you build and the views you write. Third, contact messages: the name, email address, subject and message you submit through the contact form. Fourth, where Ask Prevo is available to you, the questions you ask it and its answers (see section 5).
Our hosting infrastructure also keeps standard technical logs, such as IP addresses and browser details, used for security and operations. The site runs no analytics or advertising scripts, shows no ads, and does not sell personal data to anyone. Ask Prevo records content-free counts of its own use (which task was chosen, whether an answer was found and helped, how long it took), with no text, no account and no session attached.
2. Cookies
The site sets cookies to keep you signed in and, where Ask Prevo is available, to keep your conversation with it: a random session token, a one-time token while you save a conversation to an account, and a number from 0 to 99 that decides whether you are in an early group trying it. None of them tracks you across other sites, and there are no third-party tracking cookies, which is why there is no cookie banner.
3. How we use it
To run the service you signed up for, to answer messages you send, and to protect the site against abuse. Sign-in emails are the only email the service sends today; if that changes, unsubscribing from anything non-essential will be one click.
4. Where it lives
Prevo uses three providers processing data on its behalf: Supabase, which provides the database and authentication; Vercel, which provides hosting; and Anthropic, which provides the AI model behind drafted views and, where it is switched on, behind Ask Prevo (section 5). Each is bound by its own security and data-processing commitments; under Anthropic's commercial terms, data sent to it is not used to train its models. Prevo does not share your personal data with anyone else.
5. Ask Prevo
Ask Prevo answers from Prevo's published records. Without an account, a conversation is kept on Prevo's servers for 7 days from when it started and then deleted; you can clear it sooner from its menu. It moves to an account only if you choose to save it, sign in, and confirm on a review page. Saved conversations are kept until you delete them or close your account.
E-mail addresses, phone numbers and NRIC numbers are removed from your messages before they are kept. When Prevo's own search cannot read a question, or you ask for an explanation, the question and the records retrieved for it may be sent to Anthropic to interpret or explain. Conversations are not sold, not shared with agents or developers, and not used to train models.
6. How long we keep it
Account and research data are kept while your account exists and are deleted when you ask us to close it. Contact messages are kept as long as needed to respond and for a reasonable record afterwards, and are deleted on request.
7. Your rights
Under Singapore's Personal Data Protection Act you can ask what personal data we hold about you, ask for it to be corrected, and withdraw consent, which for an account means deletion. All of these start at the contact page, and none of them requires a reason.
8. Changes
When this policy changes materially, the change and a new date will appear on this page. The current version is always at this address.
