Privacy Policy

Last updated November 6, 2026. What sheetnest.io and the SheetNest app keep about you, why, for how long, and how to see or delete it. In short: only what we need, never sold, and your account is yours to delete.

Who we are

SheetNest and sheetnest.io are made by Manuel Rosa ("we", "us"). Write to Sheetnestusa@gmail.com about anything in this policy.

What we keep

Your account

  • What you write when you register: first and last name, email, phone, company, country, state or province, and your cutting machine.
  • Your password, only as a salted hash: nobody, us included, can read it.
  • Whether you want emails about new builds and posts.
  • When you created and confirmed the account, when you last logged in, and which files you downloaded and when.

Problem reports and messages

When you choose to send a problem report or a message, from SheetNest or from the support page, we keep what you wrote, the email you give us if you give one, the build of SheetNest and the version of Windows. A problem report also carries the technical details of the error, which can include the names of files and folders on your computer. SheetNest sends nothing unless you click to send it.

Server logs

Like every web server, ours writes a line for each request: your IP address, the date and time, the page or file, and what your browser says about itself and the page you came from. Our own statistics service counts visits from these lines (pages, sources, browsers and countries) without keeping IP addresses. There are no advertising or tracking scripts on sheetnest.io.

What SheetNest checks by itself

SheetNest asks sheetnest.io whether there is a newer build. That request carries nothing about you or your work beyond what any web request carries. Your drawings, nests and programs never leave your computer.

Why we keep it

  • Your account: to let you log in and download SheetNest and the posts, to send you the links that confirm your email or set a new password, and to know who uses SheetNest and which machines need a post next.
  • Emails about new builds and posts: only if you ticked the box. Write to us and we stop them.
  • Reports and messages: to fix SheetNest and to answer you.
  • Server logs: to keep the site running and safe, for example to stop someone trying passwords, and to count visits and downloads.

If you are in the European Economic Area or the United Kingdom: we keep your account to give you the service you asked for, the logs and the statistics in our legitimate interest in running a safe site, and the emails about new builds with your consent.

Who else sees it

We do not sell your details, and we do not share them for advertising. Two kinds of service providers handle them for us and only to run sheetnest.io: the company that hosts our server, in the United States, and an email delivery service that sends the confirmation and password links (it gets your email address and that message). We give your details to anyone else only if the law makes us.

How long we keep it

  • Your account: until you delete it. Deleting it removes your details, your sessions and your links at once; the count of downloads stays, without your name.
  • Reports and messages: while they help us fix SheetNest or answer you. Ask us and we delete yours.
  • Server logs: about 14 days. The daily counts of visits and downloads made from them hold no IP addresses.

Cookies

sheetnest.io sets one cookie, and only when you log in: the session cookie that keeps you logged in, for up to 90 days or until you log out. It is needed for the account to work, so the site does not ask for cookie consent. When you pick a language on the site, your browser remembers it in its own storage; that never reaches us.

Your choices and rights

  • See your details in your account, and delete the account there at any time.
  • Write to us to get a copy of your details, to correct them, to delete a report or a message, or to object to how we use them. We answer within 30 days.
  • If you are in the European Economic Area or the United Kingdom, you can also complain to your data protection authority.

Security

The site works only over HTTPS. Passwords are stored as salted hashes, sessions and links as hashes, links expire and work once, and repeated failed logins are slowed down and blocked. No system is perfectly safe; if something happens that puts your details at risk, we will tell you.

Children

SheetNest is made for shops and companies, not for children. Accounts are for people 16 or older.

Changes

When this policy changes, the new version goes on this page with its date. If a change matters for how we use your details, we also email account holders before it takes effect.
