Who we are

Quasarus runs quasarus.co and decides what happens to the information described in this notice.

Sales outreach

Quasarus Limited, a company registered in Hong Kong, calls and emails businesses to offer its services. Address: 8/F., 8-12 Hennessy Rd, Admiralty, Hong Kong Island, Hong Kong. Email: info@quasarus.co.

We find businesses on Google Maps, through web search and in company registers such as Companies House, and read their public websites. We keep the business’s name, website, phone numbers and email addresses, what these sources say about it, and the name and role of the person we speak to, if they give them or the website shows them.

We record our calls, and any voicemail you leave us, and say so at the start. We keep the time, length and outcome of each call, and our notes. ElevenLabs transcribes the recording. Anthropic’s Claude then writes a review for our team: a summary, what was agreed, next steps and short quotes. It only suggests. A person decides what to do.

We do this to offer our services to businesses, on the basis of our legitimate interests. You can object at any time: say so on the call, reply STOP to any email from us, or write to info@quasarus.co. We then add your number or email address to our do-not-contact list, kept only in masked form, and stop contacting you.

Who handles it for us: Supabase (our database and call recordings, in London), Vercel (our sales software, in London), Twilio (calls and recordings), ElevenLabs (transcripts), Anthropic (reading business websites and reviewing calls) and Apify (Google Maps and search results). Quasarus is a Hong Kong company and several of these services are US companies, so your data may be handled outside the UK and the EU.

Twilio deletes its copy of a recording once we have stored ours. Transcripts are deleted 180 days after the call, and copies of web pages we read after 90 days. Research on a business we don’t add to our sales records is deleted 12 months after we last updated it, 90 days after we decide not to contact it, or within a day of it asking us to stop. Recordings, reviews, notes and contact records have no deletion date yet: we keep them until you ask us to delete them. Your do-not-contact entry stays, so we don’t contact you again.

You can ask what we hold about you, or ask us to correct or delete it, at info@quasarus.co. You can also complain to your data protection authority, such as the Information Commissioner’s Office in the UK (ico.org.uk) or the State Data Protection Inspectorate in Lithuania (vdai.lrv.lt).

What this website collects

No analytics, no advertising cookies, no tracking pixels and no fingerprinting. The site does not send form data to a server.

The brief on the contact page

The brief is put together in your browser. “Copy brief” puts the text on your clipboard. “Open in mail app” opens your own email client with the text filled in. Nothing reaches us until you send the email yourself.

The referral page

The form at quasarus.co/refer works like the contact brief. It is put together in your browser, and nothing reaches us until you send the email yourself.

If someone introduces you to us

A referrer may pass us your name and contact details after you agree to it. We use them only to follow up on that introduction. We tell you who introduced us, and we stop if you ask us to.

If you are a referrer, we keep your contact details and the details of your introductions to run the program and to pay you.

Stored on your device

Your browser may keep two things for this site: your motion setting, and an unsent brief draft so you don’t lose it on reload. Both stay on your device and never reach us. Clearing your site data removes them.

Server logs

Our host, Vercel, keeps standard request logs (IP address, browser and time) for operation and security. We don’t analyse them in the normal course.

Services your browser contacts

Google Fonts, for the typefaces Schibsted Grotesk and Geist Mono, and Onest and IBM Plex Sans Thai on the referral page. Loading the page sends your IP address and browser details to them, under their own privacy terms. Vercel hosts the site.

Emails you send us

If you write to info@quasarus.co, we keep your message and our reply in our mailbox for as long as it is useful to the conversation. We use it to reply. We don’t enrich, sell or share it.

Leads from client campaigns

When we run campaigns for a client, the people who enquire are that client’s leads. Their details go into the client’s own CRM, inbox or messaging accounts and are covered by the client’s privacy notice. We handle that data only on the client’s instructions, inside the client’s systems.

If you enquired through one of those campaigns, write to the business you contacted. If you write to us instead, we’ll pass your request on to them.

Your rights

You can ask us to confirm what we hold about you, to correct it, or to delete any email you’ve sent us, by writing to info@quasarus.co. We answer these requests under the data protection law that applies to you.

Changes

We update this notice when what the site does with information changes. The version on this page is the one in force, and the date above shows when it last changed.
