Your focus data stays on your PC.

FocusFlow is a desktop productivity app for Windows that enforces focus sessions by blocking distracting applications and locking your desktop. This policy explains what the app stores, what system access it uses, and how your data is handled.

Last updated: May 2026  ·  Applies to: FocusFlow — Deep Focus App Blocker for Windows (Desktop) v1.0.3+

Local-only storage

FocusFlow stores all data locally on your Windows PC in a SQLite database file at %USERPROFILE%\.focusflow\focusflow.db. This includes:

• Tasks, schedules, and recurring task rules
• Focus session history, durations, and notes
• Focus Launcher session configuration (kiosk mode settings, PIN hash, break preferences)
• App block rules, keyword blockers, and block schedules
• Daily allowance settings and usage logs
• Habit tracking data and streaks
• Daily notes and app settings
• Temptation log (which blocked apps were attempted and when)

No data is transmitted to or stored on any FocusFlow-operated or TBTechs-operated server. None of this data ever leaves your device.

No account system or backend

FocusFlow does not require a user account, email address, or any form of registration. There is no FocusFlow backend service, cloud sync, or remote database. The app operates entirely offline and locally on your device.

Windows system access used

• Process enumeration and termination: FocusFlow reads the list of running Windows processes to detect blocked applications during focus sessions or always-on enforcement, and terminates them using Win32 APIs. It does not read process memory, file contents, or private data from other applications.
• Win32 API / JNA: Used to detect the foreground window (via SetWinEventHook and GetForegroundWindow), send close signals to blocked application windows, and manage the Windows taskbar state during Focus Launcher kiosk sessions. No keystroke logging, screen recording, or clipboard access is performed.
• Focus Launcher (taskbar control): During a Focus Launcher kiosk session, the app hides the Windows taskbar to create a distraction-free desktop. The taskbar is restored unconditionally when the session ends, when the app exits normally, when the JVM shuts down, and via a global crash recovery handler. At no point is the taskbar state stored off-device.
• Windows Firewall (optional): When network blocking is enabled for a specific app, FocusFlow adds an outbound block rule via netsh advfirewall. These rules are associated with the app's blocking session and are removed when blocking is disabled. This requires administrator privileges.
• Hosts-file blocking (optional): When website blocking is enabled, FocusFlow adds entries to C:\Windows\System32\drivers\etc\hosts to block specific domains. This requires administrator privileges. Entries are removed when blocking is disabled.
• System tray: Used to display a tray icon and provide quick controls (restore window, toggle blocking, quit) while the app runs in the background.
• Windows Registry (optional, opt-in): If the user enables "Start with Windows" in Settings, FocusFlow adds a single entry to HKCU\Software\Microsoft\Windows\CurrentVersion\Run. This is an explicit user opt-in and can be removed at any time from the Settings screen.
• File system (user profile only): Used to read and write the local SQLite database, automatic backups, and crash log in %USERPROFILE%\.focusflow\. FocusFlow does not access files outside this directory except for the hosts file (when website blocking is enabled) and the registry key described above.
• Auto-backup: FocusFlow creates periodic rolling backups of your local database within the same .focusflow folder. These backups never leave your device.

What FocusFlow does not collect

• No location data
• No camera or microphone access
• No keyboard input, clipboard contents, or screen recordings
• No passwords or credentials of any kind
• No payment data
• No usage analytics sent to any server
• No crash reports transmitted externally (crash logs are written locally only at %USERPROFILE%\.focusflow\crash.log)
• No device identifiers, hardware IDs, or fingerprinting
• No content from other applications

Windows App Package (MSIX) and Microsoft Store

The Microsoft Store version of FocusFlow is distributed as an MSIX package. The app declares the runFullTrust restricted capability, which is required to enumerate and terminate running processes and manage the Windows taskbar and firewall rules for focus enforcement. This capability is not used to collect, transmit, or store any data beyond what is described in this policy.

Microsoft may collect standard Store usage data (installs, updates, crashes) as part of its normal platform telemetry, independent of FocusFlow. This is governed by Microsoft's own privacy policy, not TBTechs'.

Your control

You can uninstall FocusFlow at any time through Windows Settings → Apps. To remove all stored data, delete the %USERPROFILE%\.focusflow\ folder after uninstalling. To remove any Windows Firewall rules added by network blocking, open Windows Defender Firewall → Outbound Rules and delete rules named "FocusFlow - Block [appname]". No data remains on any server because none is ever transmitted there.

Children's privacy

FocusFlow does not knowingly collect any personal data from anyone. Since no personal data is collected or transmitted, the app is appropriate for use regardless of age. Parents may use FocusFlow to manage focus sessions on shared or family devices.

Policy changes

This Privacy Policy may be updated at any time without prior notice. The latest version is always at this URL. We recommend reviewing this page when updating the app. Continued use of FocusFlow after any update constitutes your acceptance of the revised policy.

Open source

The Windows desktop source code is available at github.com/TITANICBHAI/FocusFlow-jvm. If the app's data handling changes in a future version, this policy will be updated to reflect it, and the change will be visible in the repository commit history.
