NorthStar is run by one person on his own hardware. This page says what it stores, where that lives, and who else can touch it.
Who is responsible
Maj Mohar runs this service. For anything about your data, including a copy of it or its deletion, write to [email protected].
What NorthStar stores
- Your account: an email address and a display name, used to sign you in and to tell you when your account is approved.
- Your calendar: a mirror of the calendar you connect, so the app works offline.
- Your notes: typed text and handwriting, with the day or lesson they belong to.
- Your settings: the way you have set the app up.
Your notes stay yours
Notes are never written back to your calendar. Outlook and Google receive nothing you write here. They are stored separately, they travel encrypted, and they are not read, mined or shared. Nobody other than you sees a note, and no feature exists that would show one to anyone else.
Where it is stored
On your devices, and on a server run by Maj Mohar. It is not stored with a cloud provider. Backups are encrypted and kept on a second machine under the same control. Both machines are in Slovenia.
Who else is involved
Cloudflare carries traffic between you and the server. Zoho delivers the few emails the service sends. If you connect Google Calendar, Google sees that connection and the events it holds. If you use an Outlook calendar link, Microsoft serves that calendar. None of them receive your notes.
Error reports
When a build has error reporting switched on, a crash sends a report to a server run by Maj Mohar. Note text, event titles, calendar links and anything token shaped are removed on your device before the report is sent. Screenshots are never attached.
How long it is kept
Until you delete it. When you delete your account, your notes and account data are erased from the live service within 30 days. Backups are a separate matter and this page will not pretend otherwise: a backup is a sealed copy of everything, it is never edited to remove one person, and your data can stay inside one for up to a year before that whole backup is destroyed. That length is not a choice about your data. It is what one person maintaining a server can actually keep on top of, and saying so is more useful to you than a shorter number that would not be true.
Nothing is ever restored from a backup in order to bring a deleted account back.
What you can ask for
A copy of your data, a correction, or its deletion. The app also lets you export your notes and delete your account yourself. Write to [email protected] and you will get an answer.
Changes
If this page changes in a way that matters, the date at the top changes and you will be told in the app.
