This policy describes what twirl collects and why.
What we collect
Account: your email address, and a username if you set one.
Usage: materials you generate (including prompts and map files), whether they are public, credit balances, and billing plan.
Device: the device type, browser, and operating system you signed up with and last signed in with, read from your browser's user agent. We use this to see how twirl is used.
Signup source: the page you signed up from. If you accept analytics cookies, also the site that referred you, any campaign tags in the link, and the first page you visited and when. Until you sign up, this is kept in your browser.
Search: what you type in the material search, when, and how many results came back, linked to your account if you're signed in. We use this to improve the library.
Billing: payments go through Lemon Squeezy. We receive the subscription and order details needed to grant credits. We don't store your full card number.
Technical: server logs and Vercel Analytics (pages you visit, referrer, approximate location, device and browser). Vercel Analytics uses no cookies and isn't tied to your IP address. Auth and database run on Supabase.
How we use it
To run the service: sign you in, generate and store materials, bill you, prevent abuse, and see how the site is used.
Public materials, including prompts shown on the site, are visible to anyone.
Who we share with
We don't sell personal information.
We use other companies to run twirl:
Supabase for auth and data.
Vercel to host the site and analytics.
fal.ai to run the Patina model that turns your prompt into maps.
Lemon Squeezy to process payments.
They see the data needed to do that job.
Cookies
We use cookies and similar storage to keep you signed in, remember your cookie choice, and, if you accept, save how you found twirl. Analytics runs without cookies. Choose Reject in the banner or under Cookies to turn it off. Sign-in cookies are required for an account.
Retention
We keep account and material data while your account is open. You can delete materials you own. Email twirl@twirl.tools to close your account. We'll delete personal data we don't need to keep for billing, security, or law.
Your rights
Depending on where you live, you can ask to access, correct, or delete personal information, or to export it. Email twirl@twirl.tools.
Children
twirl is not for children under 13.
