Privacy Policy
Last updated: June 11, 2026
Flute generates video ad creatives for your brand and shows you how they perform. To do that we handle a small, specific set of data. This policy explains exactly what we collect, why, who processes it, and how to delete it.
1. What we collect
- Account data. Your email address and authentication identifiers, managed through Supabase. If you sign in with a magic link, we send it via our email provider.
- Brand and creative-profile information you provide. Your industry, target audience, and any website URL you ask us to read to build your brand profile.
- Creative content. Reference images and videos you upload, the prompts you write, and the videos Flute generates for you, organized per Space.
- Connected ad-platform credentials. When you connect an ad platform (such as Meta), we store the access token and ad-account IDs needed to fetch your metrics, along with the read-only performance data they return — spend, impressions, conversions, and similar aggregate figures.
- Basic technical logs. Standard server logs (IP address, browser type, timestamps, request paths) used for security, debugging, and abuse prevention.
2. How we use your data
We use your data for one purpose: operating Flute. That means generating your creatives from your references and brand profile, showing your own ad metrics back to you, and storing your work per Space so you can return to it. We do not sell your data, and we do not use your content to advertise to others. Ad-platform metrics are displayed only to the account that connected them.
3. AI processing
Flute is an AI product, and we want to be precise about what that means. When you request a generation, the references you uploaded and the prompts you wrote are sent to AI providers to produce your content: video generation is performed by ByteDance/Volcengine (Seedance), and text and vision drafting — such as turning your brand profile and references into a creative brief — is performed by Anthropic (Claude). Content is sent to these processors solely to fulfil your generation requests.
4. Subprocessors
The following providers process data on our behalf:
| Provider | Role | What they process |
|---|---|---|
| Vercel | Web hosting | Serves the Flute web application and receives standard request logs. |
| Fly.io | API compute | Runs the Flute backend that orchestrates generation and stores task state. |
| Supabase | Authentication & database | Stores your account email, auth identifiers, and application data. |
| Cloudflare R2 | Media storage | Stores references you upload and videos generated for you. |
| Volcengine / ByteDance | Video generation (Seedance) | Receives your prompts and references to generate video creatives. |
| Anthropic | AI drafting (Claude) | Receives prompts, brand context, and reference imagery to draft and refine creative briefs. |
| Meta Platforms | Ad insights (optional) | Provides read-only performance metrics for ad accounts you choose to connect. |
| Resend | Transactional email | Sends sign-in links and account email on our behalf. |
| Stripe | Payments (when billing launches) | Will process payment details when paid plans go live; Flute never stores card numbers. |
5. Meta platform data
When you connect a Meta ad account, Flute requests read-only insights access (the ads_read permission) for the specific ad account you choose. We never post on your behalf, never create or modify ads, and never access personal profiles. Disconnecting the platform in Settings removes our access and deletes the stored connection, including its access token.
6. Retention and deletion
- Renders. Deleting a render removes its files from storage.
- Spaces. Deleting a Space permanently purges all of its content and connections.
- Platform connections. Disconnecting a platform deletes its stored token.
- Your account. For full account deletion, email support@flute.ink and we will remove your account and associated data.
7. Cookies
Flute uses only essential and functional cookies — no advertising or tracking cookies. See our Cookie Policy for the full list.
8. Changes and contact
If we make material changes to this policy, we will update this page and revise the date at the top. Questions, requests, or concerns: email support@flute.ink.
