Privacy policy

Last updated: 10 November 2026

The short version

  • Your spreadsheet never leaves your browser. We do not receive it, store it or see it.
  • We hold the details needed to run a paid subscription: your email, and the Stripe customer and subscription it belongs to.
  • If you create a short share link, the dashboard's data is stored on our server so the link works for other people. That is the only time your data is stored, and you choose it.
  • We count visits ourselves with a small first-party counter that records the page path, the site you arrived from, any utm_* campaign tags in the link and whether the visit looked like a bot — never your IP address, and no cookie or device fingerprint.
  • We do not sell data, and there are no advertising trackers or third-party analytics on this site.

What happens when you open a spreadsheet

Your file is read by your own browser. Nothing is uploaded, and no copy is sent anywhere. Charts, reconfiguring tiles and the PDF export all happen locally. When you close the tab, nothing about the file remains with us.

What we hold if you subscribe

Payments are handled by Stripe. Your card details go straight to Stripe and never reach our servers. From Stripe we receive and store:

  • the email address you paid with
  • the Stripe customer and subscription identifiers
  • the subscription status (active, cancelled, and the renewal date)

We keep this so you can sign back in on another device instead of paying twice, and so we can answer a billing question. We do not store your card, your address or your tax details.

Your browser also stores a licence — a signed token containing the subscription identifier and an expiry date — in local storage. It is how the app knows your plan is active without an account. Clearing your browser's site data removes it; you can restore it by signing in with your email.

If you create a short share link

A short link (/s/…) stores the dashboard's contents — the data shown in your charts — on our server so that anyone with the link can open it. Only create one for data you are happy to have stored, and remember that anyone holding the link can view it.

The alternative is the full link, which carries the dashboard inside the URL itself and is never stored by us. Both can be shared with anyone.

Email sign-in

If you sign in with your email, we send a six-digit code to that address. The code is stored hashed, expires after ten minutes and works once. Sending it requires our email provider (see below).

Who else is involved

  • Stripe — payments, invoices and the billing portal.
  • Our email provider — delivers sign-in codes. It receives the address and the message.
  • Our hosting and network providers — serve the site and may keep standard technical logs (such as IP address and request time) for security and reliability.

We do not sell or rent personal data to anyone.

How long we keep things

  • Subscriber records — while the subscription is live, and afterwards for as long as needed to deal with billing questions.
  • Sign-in codes — minutes, then discarded.
  • Short share links — until they are removed; a link can stop working when the site is updated.

Your choices

Email us at [email protected] to ask what we hold about you, to correct it, or to have it deleted. If you have a subscription, cancelling it in the billing portal stops all future charges; ask us to delete the subscriber record afterwards if you want it gone.

Children

This is a tool for people working with business data. It is not intended for anyone under 16.

Changes

If this policy changes in a way that affects what we hold, the date at the top changes with it.
