S2NodesPrivacy notice
Last updated: 10 November 2026
In short: S2Nodes asks for a few details when you download an app or report a bug. They're used only to send you the download, support you and, if you choose, send occasional updates. They're never sold. Our apps themselves run offline and never send your documents anywhere.
Who we are
S2Nodes (s2Nodes.com) is run by Haard Shah, India. For anything about your data, write to hello@s2nodes.com.
What we collect, and why
- When you download an app: your name, firm or organisation, email address, mobile number, profession, and whether you chose Mac or Windows. We use them to email you the download link, tell you about important fixes for the version you downloaded, and understand who uses our apps.
- Newsletter (only if you tick the box): occasional emails about new versions and new S2Nodes apps. You can unsubscribe with one click in any email.
- When you report a bug: your name, email, the details you write and any screenshot you attach. We use them to fix the problem and reply to you.
What our apps collect
Your documents, never. Our apps run on your computer, don't upload your files and contain no analytics or tracking.
Licence and updates. When you activate a licence key, SideNotes sends us the key, the app version, your computer's name and operating system, and an anonymous computer ID (a one-way code made from the computer's hardware ID). It re-checks the key about once a week and asks whether a newer version exists. We use this only to make each key work on one computer, to let you move it to a new computer, and to stop misuse. We also see the IP address the request comes from.
Where it's stored
Your details are stored with our email service provider, Brevo, which sends the emails for us, and as a backup on our own web server. Licence keys and activation records are kept in a database on our own web server. We don't sell, rent or share them with anyone else.
How long we keep it
For as long as you use our apps or stay subscribed. If you ask us to delete your details, we will.
Your choices
- Unsubscribe from updates using the link at the bottom of any email.
- See, correct or delete your details by writing to hello@s2nodes.com. We'll respond within 30 days.
- Withdraw consent at any time, in the same way.
