Legal

Terms + Privacy.

One page, plain language. What we keep, what we don't, what we promise.

1

What this is

Corner is a public priority-establishment registry. You stake a file's hash; multiple Time Stamp Authorities witness it; the receipt is yours to verify offline forever. This page tells you what we keep, what we don't, and what we promise.

Data we keep

  • Your email — for signup, login, and recovery.
  • Your optional profile fields (display name, default claim type, default jurisdiction, default link) — only if you fill them in.
  • Your receipts — file hash, optional file (only if you chose public mode), optional attestation, TSA proof tokens.
  • Your talk thread posts.
  • Server logs (IP + timestamp on requests), retained briefly for abuse prevention.

Data we don't keep

  • No analytics. No tracking pixels. No third-party JavaScript. Cloudflare Turnstile is the only third-party network call, on signup / sign-in / stake forms, anti-bot only.
  • No selling, no sharing, no advertising.
  • No raw IPs retained beyond rate-limit windows.

Cookies

Authentication session cookie only (Supabase auth). No other cookies.

How to delete

Visit /dashboard/account and use the Delete account button. Your account, profile, and talk posts are deleted. Your receipts remain on the public registry without your name attached — see "Why receipts persist" below.

Why receipts persist after account deletion

Receipts are timestamped public claims. Deleting them retroactively would break the priority-establishment promise to anyone who relied on the timestamp.

If you want maximum privacy at stake time: use hash-only mode. Your file never touches our servers. We have only the hash.

License

  • Code: AGPL-3.0 (see the LICENSE file in the repo).
  • Your content: you retain copyright. By staking, you grant us the right to host the file (if you chose public) and the receipt forever.
  • Talk posts: you retain copyright; we host them publicly until you (or admin moderation) soft-delete them.

No warranty

Corner is provided as-is. We can't guarantee TSA continuity, our hosting continuity, or the indefinite availability of any particular receipt page. The receipt is yours; download the bundle and keep your own copy.

Changes to this page

We'll change this page as the product evolves. We won't retroactively change the data-keeping promise without telling you.
