Privacy Policy & Security Specs

Last updated: October 25, 2026 • Zero-Server Local Processing Standard

100% Local Storage

Tour steps, screenshots, and metadata stay strictly inside your local IndexedDB.

Local WebCodecs

60fps 4K MP4 videos are rendered directly on your GPU without sending frames to any cloud.

Zero Audio/Keystroke Logs

FlowTour never captures microphone audio, keyboard strokes, or background tabs.

01.Zero-Backend Architecture & Data Isolation

FlowTour is engineered strictly on a client-side, zero-backend architecture. When you record a product tour, the captured element selectors, click coordinates, step descriptions, and high-resolution viewport screenshots are stored entirely within your local browser storage using chrome.storage.local and IndexedDB.

FlowTour does not run any backend API servers that collect your captured application flows or recorded video assets. If you uninstall the extension or clear browser application storage, all local recordings are permanently deleted.

02.Local WebCodecs Hardware Video Rendering

Unlike legacy walkthrough and demo platforms that upload uncompressed screen recordings to cloud servers for remote rendering, FlowTour performs all 4K/1080p 60fps video rendering locally using the W3C WebCodecs API and Canvas 2D:

  • Hardware Accelerated: Video frames are encoded into standard H.264/MP4 files directly on your local device GPU/CPU.
  • Zero Cloud Ingestion: Not a single image frame, DOM snapshot, or video pixel is ever uploaded to an external server.
  • Export Privacy: Exported MP4 videos download directly to your local file system via browser Blob URLs.

03.Chrome Permissions & Scope

FlowTour requests only the minimal Manifest V3 permissions required to capture walkthroughs:

sidePanelProvides a docked, non-intrusive recording and step editing studio.
activeTab & tabsCaptures element clicks and screenshots strictly on the active tab being recorded.
scriptingInjects non-invasive click detectors and highlight boxes during active recordings.
storage & unlimitedStorageStores tour step timelines and screenshot buffers locally on your machine.

04.Payment Data & Security

Pro Lifetime license transactions are processed securely through Dodo Payments. Dodo Payments is a PCI-DSS compliant Merchant of Record. We never receive, collect, or store credit card numbers, CVVs, or billing card records on any server.
