What we store

• Your account: your email address and your Google or GitHub account number, as they sent them when you signed in. There’s no password: we never have one.
• A session cookie (__Host-sd_session) that keeps you signed in for up to 30 days. It’s strictly necessary, so there’s no cookie banner. We store only a hash of it.
• Your devices and dashboards: the names you give them and the layout of your graphs.
• Readings your boards send: numbers and field names with a timestamp. Raw readings are deleted after 30 days, per-minute averages after a year.
• Server logs without your email, keys or readings, kept by Cloudflare for a few days to find errors and abuse.

What we don’t do

No ads, no tracking scripts, no analytics, no third-party requests from your browser. We don’t sell or share your data. The site keeps your theme choice and which USB ports you’ve connected in your browser’s local storage. That never leaves your computer.

Who processes it

Cloudflare hosts the site and the databases. When you sign in, Google or GitHub tells us your verified email address and your account number with them, nothing else. Their own privacy policies cover what they keep.

Your choices

Download any device’s readings as CSV from the dashboard. Delete a device to delete its readings, or delete your whole account from the account page: everything goes straight away. For anything else, email us.
