NanoSweep Privacy
Privacy Policy
Privacy information for NanoSweep, a local-first provenance passport for antenna and feedline sweep records.
Effective: July 30, 2026 | E Stream Media Empire
This Privacy Policy applies to NanoSweep ("NanoSweep", "the app"). NanoSweep helps users preserve calibration sessions, immutable snapshots, comparison review state, imported provenance, site notes, photos, backup archives, export packages, and handoff history.
Local-first records
NanoSweep is designed around records stored on the device. The app does not require an account, developer-operated cloud sync, or a developer server database for the core passport, measurement, backup, restore, or export workflow.
Information you choose to enter
You may enter passport names, antenna aliases, calibration summaries, frequency spans, port and feedline descriptors, site-condition signatures, notes, labels, timestamps, and handoff details. You may also attach site photos where supported by the app.
Imported sweep files
If you choose to import a CSV, S1P, or S2P file, NanoSweep treats that file as provenance evidence. The app records detected type, file name, SHA-256 hash, preview metadata, duplicate-detection state, and any confirmed snapshot linkage so later review can trace where evidence came from.
Backups and export packages
NanoSweep can create backup JSON archives and export packages when you ask it to. These files are created locally, can include provenance records and missing-source declarations, and leave the device only when you choose a destination through sharing or file export.
No advertising, tracking, or developer analytics
The current app does not use advertising SDKs, third-party analytics SDKs, tracking SDKs, or third-party crash-reporting SDKs for the core NanoSweep workflow.
Purchases and Restore Purchases
Optional Monthly, Yearly, and Lifetime access products are handled through Apple StoreKit where available. E Stream Media Empire does not receive full payment card details from Apple purchase flows.
No RF control or engineering conclusion
NanoSweep preserves evidence and workflow context only. It does not control a VNA or other RF hardware, does not diagnose RF issues, does not recommend tuning or corrective action, and does not issue engineering, compliance, certification, or safety conclusions.
