What gets sent when a formula runs

The text in the cells you point a formula at, your question, and the options or levels you wrote. It travels from Google Sheets to our server, and from our server to TypeSafe, whose Jev model computes the answer. Nothing else in your spreadsheet is read.

What we store

• Your key, its credit balance, how many rows it has used, and when it was last used.
• The email address and Stripe session id from your purchase, so we can find your key if you lose it.

We do not store the text of your cells, your questions, or the answers. They pass through and are gone when the response is sent back to your sheet.

What stays in your sheet

Answers are cached inside your own spreadsheet for six hours using Google's document cache, so recalculation does not spend credits. That cache is part of your Google account, not ours.

Third parties

• TypeSafe computes the answers. Their published policy states that customer requests are not used for training. See docs.typesafe.ai/legal.
• Stripe handles payment. We never see your card details.
• Cloudflare runs our server and stores keys and balances.
• Google runs the spreadsheet and the script inside it, under your own Google account and Google's terms.

Permissions the script asks for

Three, and only when you use the Hunch menu: read and write the current spreadsheet, connect to our server, and show a dialog. Formulas alone need no authorization. The script cannot open your other files, read your email, or see your Drive.

Deleting your data

Email us with your key or purchase email and we delete the key record. Unused credits on a deleted key are gone with it.
