TimeCairn

Legal

Terms + Privacy.

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

1

What this is

TimeCairn is a public priority-establishment registry. You stake a file's hash; multiple Time Stamp Authorities witness it; the receipt is yours to retain and verify with the required evidence and trust material. 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 attestation, and timestamp proof tokens. A file is uploaded to publicly readable storage when you submit a public-file option. The form starts with Public + download if you have no saved preference. Receipt records start private; that setting does not restrict access to an uploaded public file. The hash-only option sends the digest and metadata instead of file bytes.
  • 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.

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

TimeCairn 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.
