Support
Happy to help. Most questions are answered in the docs, and you can always reach a real person by email.
Get in touch
Email [email protected] with questions, bug reports, or feature requests. Jotsum is made by one person, so replies usually come within a couple of days. Including your macOS version and a short description (or screenshot) of what happened helps a lot.
Documentation
The documentation covers everything Jotsum can calculate — variables, percentages, units, currency, dates, time zones, functions — plus all the keyboard shortcuts.
Common questions
Where is my data stored? Entirely on your Mac, in the app's sandbox. Nothing is uploaded. See the privacy policy.
Does it need an internet connection? No — Jotsum works fully offline. The only thing that uses the network is live currency conversion, and even those rates are cached so they keep working offline.
How do I export a sheet? Press ⌘E and choose CSV, PDF, HTML, or Markdown.
I deleted something by accident. Deleted sheets go to Trash and are kept for 30 days, so you can restore them.
Can I change the text size or appearance? Yes — ⌘+ / ⌘− / ⌘0 resize the text, and Settings (⌘,) switches between Light, Dark, and System.
