Privacy
This page covers the Compos website and waitlist. The app isn't out yet, and it will come with its own policy.
What we collect when you join the waitlist
Your email address. Which page you signed up on, and which version of the headline you saw. If you answer the two short questions, which phone you use and whether you have someone in mind to be your accountability partner. And the date you signed up and confirmed.
We don't ask for your name, and we don't collect anything about the person you might invite. The invite is sent from your own phone.
What we use it for
To email you when Compos is ready for your phone, and to learn which parts of the site make sense to people. We won't sell your email or use it for anything else.
Who else handles it
Our servers, and the database that holds the waitlist, run on Hetzner in Germany. Emails are sent through Resend, and replies to them reach us through Cloudflare. Page views and signups are counted with PostHog, in the EU, without cookies and without identifying you. Each of these companies processes data only to run their part of the service for us.
When you join, PostHog is told which page you joined on and your answers to the two questions. It never gets your email address. PostHog doesn't keep your IP address, but it uses it to work out roughly where you are, such as your country and city, and keeps that.
Like most websites, our servers briefly log IP addresses to keep the service running and to stop abuse, such as bots signing up in bulk.
Cookies
The site sets one small cookie so you keep seeing the same version of the page if you come back. It doesn't identify you and isn't shared with anyone.
How long we keep it
Until Compos launches and we've told you, or until you leave the list, whichever comes first. If you never confirm your email, we delete the signup after 30 days.
Leaving the list, and your rights
Every email from us has a “Leave the waitlist” link at the bottom. It deletes your email address and your answers straight away.
You can also reply to any email from us, or write to privacy@getcompos.com, and we'll delete everything we hold about you. You can ask for a copy of it first. If you're in the UK or the EU, you can complain to your data protection authority, such as the ICO in the UK.
Compos is made by Logos Ventures.
