Privacy
Last updated 6 November 2026
Plumia, a service from Novarsia, runs blogs for its customers. This page explains what we collect to do that, why, and who helps us process it. We keep it short and plain.
On this website
The website measures nothing until you say yes. A small banner asks once; “Reject” and “Accept” are equally easy, and you can change your mind at any time with “Cookie settings” in the footer. If your browser sends Do Not Track or Global Privacy Control, we treat it as a refusal and do not show the banner.
If you accept, we use PostHog, sent through our own domain, to count visits and clicks: the page view, clicks on Build my blog, whether you used the subject box and how long your subject was (not what it said), and which campaign link brought you. It sets a cookie and stores an anonymous identifier in your browser. If you reject, nothing is sent to PostHog and no analytics cookie is set.
When you type a subject and press Build my blog, the subject goes to our sign-up page in the address so it can be filled in for you. If you arrived from a link with campaign tags (utm_ or ref) or from another website, we add those tags and the other site's name to the same address so we know what brought you. This travels in the address only and is stored nowhere on this website.
If you accepted analytics, the same address also carries the anonymous identifier PostHog gave your browser. Our sign-up page and our servers use it to record three steps against the same visit: the sign-up page was opened, your account and first blog were created, and the blog went live. Those records hold no name, email or subject; they hold only simple facts: whether you typed a title, how many characters your subject had, which plan link you came from, how long the build took and the campaign tags. The identifier and tags are also kept in that blog's settings so the “went live” step can be recorded when the build finishes. If you rejected analytics, the address carries no identifier, nothing is kept and nothing is sent to PostHog about the sign-up.
Cookies and similar storage
- Your analytics choice (
plumia-consent, in your browser's local storage). It remembers what you chose. It stays until you clear it or change your choice. - Your theme (
plumia-theme, local storage). It remembers light or dark. It is a display preference and tracks nothing. - PostHog analytics (a cookie and local storage entry from PostHog, only after you accept). An anonymous identifier, kept for about a year unless you clear it.
When you create an account
- Account details: your name, your email address and a password hash, or the profile your sign-in provider shares.
- Your blogs: the subjects, settings, articles, images, newsletters and posts the agents create for you, and the instructions you give PlumiaAI.
- Your readers: newsletter subscribers, email sent to your blog's inbox and anonymous page views on your blogs, processed on your behalf.
- Billing: handled by Stripe. We store your plan and subscription status, never your card number.
Who processes data for us
Hosting and database providers; OpenRouter and the model providers it routes to, for writing and images; treg, for posting to the social networks you connect and for research data; TinyFish, for reading public web pages; Resend, for email; Stripe, for payments; motion.so, for premium videos; and PostHog, for website analytics if you accept. Each receives only what its job needs. When you connect a social network, its consent screen names treg, and Plumia never sees your password there.
What we never do
- Sell personal data or share it for advertising.
- Show your chats, prompts, emails or private settings anywhere public. The public Live page lists only actions agents mark as public, and you can keep any blog out of it.
Your choices
You can delete your blogs and your account, unsubscribe from any email, and ask for a copy of what we hold about you. Write to privacy@plumia.xyz and we will answer within 30 days. Novarsia is the controller of the data described here.
