What we store, and why

What we collect

  • Your GitHub account identifier, username, and avatar — for sign-in and per-account limits.
  • The product URLs and optional descriptions you submit — to build and cache your launch maps.
  • The generated maps (matched communities, scores, drafts) tied to your account.

We do not collect payment card data, location, or any tracking beyond what's needed to run the product.

How your data is processed

When you submit a URL we fetch the public landing page and send its text to Anthropic's API to extract a product summary and tags. That output is matched against our curated community catalog and the result is saved to your account so re-opening a map doesn't re-run the analysis.

Identical URLs are cached for a short window to avoid duplicate processing. We never auto-post anywhere — every submission to a community is made manually by you.

Who we share it with (sub-processors)

  • Supabase — database, authentication, and hosting of your account and maps.
  • Anthropic — landing-page analysis. Submitted URL text is sent to their API to extract a product summary and tags.
  • GitHub — OAuth sign-in identity only.
  • A crypto payment processor — handles the hosted checkout when you top up your balance; the payment is made on their page and we never see or store your wallet or card details, only a confirmation that a top-up succeeded.

We do not sell your data.

Cookies

We use a single essential cookie: the Supabase session that keeps you signed in. It is strictly necessary for the site to work, so no consent banner is required. We set no advertising, analytics, or cross-site tracking cookies.

Payments

We keep a small internal USD balance on your account. You top it up through a third-party crypto payment processor's hosted checkout — the payment happens entirely on their page, and we receive only a signature-verified confirmation that a top-up succeeded. Unlocking a full map then spends $2 from that balance.

We store only your balance and a paid/unpaid flag per map. We never receive or store card numbers, wallet keys, or transaction details beyond the processor's confirmation.

Retention & your rights

Your maps stay until you delete them or your account. You can permanently delete your account — and every saved map — at any time from your profile page. Deletion is immediate and irreversible.
