How micro-LEAN handles your data
Last updated 6 October 2026. This page describes what the app actually does. It is not legal advice.
Where your work is stored
| Not signed in | Your processes are saved only in this browser’s local storage, on this device. Nothing is sent to our server unless you create a share link or send feedback. |
|---|---|
| Signed in | Your processes are also saved to our server as one workspace tied to your email address, so you can open them on other devices. Each account’s work is kept separate in the browser, and signing out lets you remove it from the device. |
| Share links | Only when you choose Create link, a snapshot of that one process is stored on our server. Anyone with the link can open a copy until it expires: 7 days for links made while signed out, up to 90 days when signed in. Signed-in owners can turn a link off at any time. Expired links are deleted automatically; turned-off links are deleted 7 days later. Links created before 6 October 2026 expire 30 days after they were created. To have one removed sooner, send a Feedback note with the link. |
| Feedback | If you send feedback, we store your message, the stage you were on, an optional rating, your optional answer to “How did you find micro-LEAN?” and, if you are signed in, your email address. Please do not include client data in feedback. |
| How you found us | If you arrive through a link with a ?ref= tag (for example ?ref=linkedin), your browser keeps that short tag. The first time you start a process, the browser sends us one “started” signal with that tag (or no tag), the date and nothing else: no process data, no email address and no cookie, so we can count how many people each channel brings. If you sign in, the tag is also saved with your account; if you send feedback, with that note. Only tags from our own fixed list are kept. Nothing is shared with anyone else. |
What we do not do
- We do not call any AI model with your process data. The “rule-based draft” runs entirely in your browser. The build package is a file you choose to give to your own tools.
- We do not use advertising or analytics trackers, pixels or third-party scripts. The only cookie is the sign-in session cookie. The channel count above is our own tally of a short tag, not tracking.
- We do not sell or share your data. Emails you send from the app reach only the recipient you enter.
Service providers
- Railway hosts the app and its database.
- Resend delivers sign-in codes and share emails you choose to send.
How long we keep it
- Cloud workspace: kept until you delete your account.
- Deleted processes: stay in Trash for 30 days, then are removed from every synced device.
- Sign-in sessions: last up to 90 days. You can sign out of every device from the Account panel.
- Rate-limit records: no process content; deleted after one day.
- “Started” signals: a date and an optional channel tag, nothing that identifies you; kept as running totals.
Deleting your data
- In the browser: delete processes (then empty them from Trash), or sign out and choose “remove from this device”.
- Account: open your email address in the header → Delete my account. This deletes your cloud workspace, every share link you created and every signed-in device. Download a backup first if you want to keep your work.
