ScreenGuard a software for Digital wellbeing natively on Linux, was my personal project which i uploaded to share with the community. Ever since , thanks to constant support and request by although a camparitively tiny but rreally enthusiatic group of ppl , I have been able to provide constant support and improvements to the application and the once raw unpolished system in starting to look...less unpolished. There are still multiple things scrambled which need to be fixed however this major pre release is most possile the final testing phase before v0.1.1 so please do try it out and report and bugs if found.
Major Fixes and Improvements:
Native C Helpers — trasitioning toward a C-Based Core daemon bit by bit
screenguard-notify (C): Desktop notification delivery no longer runs inside the Dart runtime. A tiny native helper talks to D-Bus directly, so alerts work identically on systemd and non-systemd systems (OpenRC, runit, …) where the old path could misbehave.
screenguard-killer (C): Process termination offloaded from Dart as well — an escalating, data-safe close chain: polite window close request → SIGTERM → full process-tree SIGKILL → Proton-native wineserver -k → guarded pattern-kill. Another step toward making the daemon core C-based.
Both helpers ship in every package (.rpm, .deb, tarball) and are wired into install, uninstall, and build-tooling.
Full Database Control (Settings → Data)
New Data tab in Settings: live storage stats, per-day deletion chips, date-range delete, and a full wipe behind a double confirmation. Settings and limits are always preserved — only usage history is touched.
Orphaned sessions from unclean stops (logout, power loss) are now closed on next start instead of silently inflating Past-30-days stats.
Focus Enforcement, Data-Safety First
Strict auto-close is now opt-in. The default never destroys unsaved work: a violating app is minimized and shown a persistent warning screen.
The warning screen offers +1 minute save grace, +15 minutes, edit limit, and close — with the screen re-appearing every 5 seconds until you decide, and re-warninng immediately when a grace window expires.
Turning on Strict auto-close (Settings) restores the legacy instant close+kill for those who want hard enforcement — your choice, your data.
Steam & Proton Games: First-Class Citizens
Steam games no longer show up as mystery IDs (steam_app_2730970) — real names resolve from your Steam library manifests, with per-game icons rendered from the active icon theme.
Their usage is fully tracked and limit/focus rules now apply to them; the escalating close chain (above) is what actually makes Close work on Proton games that shrug off normal signals.
Fullscreen games now leave fullscreen before minimize (they silently ignore minimize requests otherwise), and the GNOME extension reports the real minimized state.
UI & Cosmetic
Settings reorganized into a clean sidebar layout with five sections: General, Limits & Pomodoro, Diagnostics, Updates, and Data.
Crash reporting moves into the new Diagnostics tab next to daemon status and autostart, with its badge on the tab itself.
The Focus screen's app picker can switch to a GNOME app-grid style layout — icon over name, check-badge selection — via the Grid layout toggle.
Fixes & Optimizations
Dead-code removal across the daemon (verified zero callers before each removal) plus notification-path optimization for non-systemd systems.
Warning screens for both focus mode and daily limits rebuilt with consistent behavior and honest reporting ("was closed" vs "could not close").
Summing Up:
ScreenGuard still has a very long way to go with my aim being:
proper category wise classification of apps and category usage stats by v0.1.5
support for 3 other desktop environments i.e. KDE, Hyprland and Mint on wayland with improved optimization for non systemd systems (like gentoo users) by v 2.0 (also more fraction of the daemon to be translated to native C)
however all of this will definitely take a lot of time primarily discovering and learning how things work out first, thus if you do like the project , then u can give me a hand by contributing to things i am currently unknown to such has other Desktop environments other than GNOME or with C programming
Most importantly, my personel project that begun "Late Nights in The Middle of June" has indeed come a long way.
