Privacy Policy
Last updated: September 2, 2026
What We Collect
When you use the BrainTube Chrome extension, we store the URLs, titles, and content summaries of pages you explicitly save. For YouTube videos, we also store transcripts and AI-generated summaries. AI conversation captures (from Claude and ChatGPT) are saved only when detected on supported pages.
Notion Integration
When you connect your Notion workspace via OAuth, BrainTube accesses page titles and text content of pages you explicitly grant access to during setup. We do not access your Notion comments, workspace settings, user lists, or any pages you haven't shared. Synced content is stored in BrainTube's database and processed for search, AI chat, and metadata enrichment. You can disconnect your Notion workspace at any time from Settings — this revokes our access and you can request deletion of synced content by emailing privacy@brain-tube.com.
Where Your Data Lives
All data is stored in a Supabase-hosted PostgreSQL database secured with row-level security. Only you can access your corpus. We do not maintain secondary copies of your data.
What We Don't Do
We do not sell, rent, or share your data with third parties. We do not serve ads. Your library content is only captured when you actively click Save or Bookmark — the extension never reads pages you don't save.
Analytics
On brain-tube.com we use PostHog, hosted in the EU, to record product-analytics events such as page views and feature usage. We also set a first-party cookie named bt_acq for 12 months that stores a random visitor ID plus how you first arrived — UTM parameters, ad-click identifiers such as gclid or fbclid, the referrer and the landing page — so we can attribute sign-ups to the campaign that brought you here; if you arrive through a partner link, a bt_partner_ref cookie stores that partner code for 90 days. These cookies do not contain your name or email, and they are not shared with advertising networks. You can delete them in your browser at any time. You choose whether these run via the consent bar on your first visit, and can change your mind at any time from Cookie settings in the footer.
Data Deletion
You can delete individual items from your library at any time. To delete your entire account and all associated data, email privacy@brain-tube.com. Deletion is permanent and irreversible.
