Effective date: April 11, 2026 · JuSenseSheet v3.x · JupiterSense
JuSenseSheet collects zero data about you or your documents. Everything runs locally on your machine. No telemetry, no analytics, no phone-home. The only time data ever leaves your machine is if you explicitly configure a third-party AI provider — and even then, it goes directly to that service, not to us.
JupiterSense does not collect any personal data, usage data, or document data. There is no account, no login, no email address required. We have no servers that receive information about you or your documents.
All invoice PDFs you process with JuSenseSheet are stored exclusively in your browser using IndexedDB on your device. Every PDF at rest is encrypted using AES-256-GCM via the Web Crypto API. The encryption key is generated and held in your browser's local storage; JupiterSense never sees it. No one but you can read your stored documents.
JuSenseSheet contains no analytics, no crash-reporting SDKs, no telemetry, and no tracking pixels. We do not know how many times you have opened the app, how many invoices you have processed, or which features you use.
After the initial page load (and any subsequent updates to the PWA), JuSenseSheet makes no network requests during normal use. Extraction, storage, and export all happen locally in your browser. The app works fully offline once installed.
The only outbound network traffic that may originate from this site is the loading of Google Fonts (DM Sans) on the marketing pages — this is loaded by your browser directly from Google, not relayed through JupiterSense.
Pro license keys are validated entirely offline using HMAC cryptography. Activating your key does not require an internet connection and does not contact any JupiterSense server. There is no "phone home" on startup, on document open, or on any other event.
When you export, JuSenseSheet writes a CSV or XLSX file to your browser's downloads folder, or — if you've granted folder access in a Chromium-based browser via the File System Access API — directly into a folder you've chosen. JuSenseSheet does not push exports to any external service. Importing the resulting CSV/XLSX into QuickBooks, Xero, Sage, or any other accounting system is something you do manually.
JuSenseSheet is professional accounting software intended for adults. We do not knowingly collect any information from anyone under 18 — and as noted above, we collect no information from anyone at all.
If we ever change how the app handles data (for example, adding an optional cloud sync, AI fallback, or webhook integration in a future version), we will update this policy and communicate the change prominently in-app and on this website before the change takes effect. Any such feature would be opt-in and disabled by default.
