I shrank enterprise construction project-controls into a single offline HTML file

After years in enterprise construction, one gap always bugged me. On a big job nobody starts without a critical path, committed-vs-paid tracking, and a contingency you actually protect. On a renovation, all of that discipline disappears into a spreadsheet and a group chat, and the budget quietly slips.

So I built Storypole (storypole.app), a free renovation budget and schedule tracker. The idea was to take that project-controls thinking and shrink it to fit a kitchen remodel, simple enough for a homeowner with no PM background.

A few build decisions I'd love feedback on:

• It's one self-contained HTML file. No backend, no accounts, no database. Data lives in the browser (IndexedDB) with an optional local backup file. It works fully offline, which matters when you're standing in a half-gutted basement with no signal.
• The free tier is a real tier, not a trial. One project, full features, forever. A one-time $29 (free for everyone during beta until Aug 1) unlocks multi-property and sync.
  Two things I'm chewing on and would genuinely value takes on:

Is "no account, offline, single file" a feature people care about, or do users expect cloud sync and I'm overthinking the privacy angle?
For a tool whose buyers (homeowners) aren't on IH or PH, where would you launch to reach them?
Happy to answer anything about the build. Thanks for reading.
