Prowrit is built by one person, funds itself with nothing (it's free), and wants exactly as little of your data as the product needs. Here is the complete picture.

What we store, and for how long

• Anonymous runs (no account): your pasted brief and the generated blueprint are stored so you can poll the result and share the card link. Both auto-delete after 30 days — this is enforced by the infrastructure itself, not by a cleanup job we might forget.
• Studio (signed-in) workflows: kept until you delete them. Deleting a workflow hides it immediately; deleting your account (below) erases everything permanently.
• Your account: your email address, held by AWS Cognito for sign-in. Nothing else — no name, no tracking profile.

What your brief is used for

One thing: engineering your workflow. Your brief is sent to Anthropic's Claude via AWS Bedrock — under AWS's terms, Bedrock does not use your inputs to train models. We don't sell, share, or mine anything you paste. Generated cards are unlisted — only people you give the link to can see them, and search engines are told not to index them.

What we don't have

No ad trackers, no analytics cookies, no fingerprinting, no third-party pixels. The site sets no cookies at all; your signed-in session lives in your own browser's storage.

What we count

Four anonymous counters, so the product improves on evidence instead of guesswork. They are tallies, not records — no identifier is attached to any of them, which also means we cannot reconstruct your session, and neither can anyone else:

• A run started — and whether it was a first attempt or a rerun carrying your answers, plus a rough bucket (1, 2, 3, 4, 5-or-more) of how many runs this browser has started. That tally lives in your browser; only the bucket is ever sent.
• A run left unwatched — you closed the tab or switched away while it was still working, and which stage it had reached. A full design takes minutes, and knowing where people give up is the only honest way to make that wait better.
• The question round — whether it was shown, answered, or skipped. Nothing about what you answered.
• Which export you used — copy the workflow, download the skill, download the eval suite, and so on. The name of the button, nothing else.

Never sent: your brief, the generated workflow, your answers, your email, or any id that could link two of these together. The server accepts only a fixed list of event names and a fixed list of values for each, so even a bug in our own code cannot smuggle your text into a counter. They become numbers in our own AWS metrics — no third party, nothing stored per person, and no cookie involved.

Erasing everything

Signed in → My studio → Account → Delete my account. This permanently erases your saved workflows, revision memories, cards, MCP key, and the sign-in itself — immediately, no email dance, no retention period. Anonymous runs erase themselves within 30 days regardless.
