Privacy Policy

• Account data: your email address, a hashed password, your workspace name, and your role in the workspace (editor or approver). We do not store your password in plain text.
• Early-access requests: the email address you enter in the early-access form.
• Free publisher check: the site address you enter, your email address, the UTM parameters in the link you followed, and the traffic source. We also store the snapshot we generate for your site.
• Data you upload: the CSV files you connect to Canon, stored as a database file in your workspace.
• Workspace activity: the metric definitions you draft and approve, the checks you save, and an audit log of the questions asked, the metric used and the answer given.
• Session cookie: a cookie that keeps you signed in, for up to 14 days.
• Site analytics: we use Vercel Web Analytics, which counts page views without cookies.

We use this data to run Canon for you: to sign you in, to profile your uploads, to draft and check metric definitions, to answer questions, and to keep the audit log. We use early-access requests to contact you about access. We use free publisher check requests to check the public pages of the site you entered and email you the snapshot.

Canon uses a third-party AI provider (OpenAI or Anthropic) for two steps. Your data rows are not sent in either step.

• Drafting metric definitions: Canon sends a profile of your upload: column names, column types, null and distinct-value counts, row and column counts, and the report's date range, currency and time zone when the export includes them.
• Answering questions: Canon sends the question you asked and the names, descriptions, dimensions and synonyms of your approved metrics, so the model can pick the right metric. Canon then computes the answer from your stored data itself.

If you publish a shared answer link, anyone who has the link can ask questions through it without signing in. Up to 100 rows of the data behind an answer can also be read through that link. Only share these links with people who may see that data.

The website is hosted on Vercel. The Canon app, its database and your uploaded data are hosted on Railway.

Uploaded data, metric definitions, saved checks and the audit log, including the answers it records, are stored in your workspace. To ask about deleting your data, your account, an early-access request, or a free publisher check request and its snapshot, email [Contact email].
