How Matterz Studio collects, uses, and protects your personal data when you use Plume.
Matterz Studio — a SASU registered with the Paris trade register under no. B 943108688, registered office 6 rue d'Armaillé, 75017 Paris, France — operates Plume (plumeos.app) and is the data controller for the information described here. Contact: hello@plumeos.app.
Account details (name, email) via our authentication provider; the brand information and content you create; billing details; and technical logs (e.g. errors, usage).
We share data only with the providers required to run Plume: Clerk (authentication), Supabase (database & file storage), Stripe (payments), Anthropic (AI text generation), Replicate (AI image generation), Resend (transactional email), Microlink (website preview during onboarding), and Sentry (error monitoring). Each processes data on our behalf under its own terms.
To provide and improve the service, generate content in your brand voice, process payments, send service emails, and keep the platform secure. We do not sell your personal data.
We retain your data while your account is active and as long as needed to meet our legal obligations. Under the GDPR you may access, correct, export, delete, or object to the processing of your data — including via in-app account deletion. Email hello@plumeos.app to exercise these rights, or lodge a complaint with the CNIL.
Plume uses strictly necessary cookies for authentication (Clerk) and payments (Stripe). We do not use advertising or cross-site tracking cookies.
