Takvim / Habit Tracker / Dosya Dolabı / Aktenak / X / Feedback
I'm Arda, a.k.a. Tungarix. I'm an Electrical & Electronics Engineering student and co-founder of Aktenak, a two-person software studio, where I handle the code and systems side.
This is where my tools live in the open: download them, read the code, and tell me when something breaks.
|
01 / CALENDAR
A local-first desktop calendar. No account, no internet: your data stays on your machine. |
02 / HABITS
A local-first habit tracker. Habits, mood, tasks and focus sessions in one panel. |
03 / AI
Two open-weight models on 8 GB of VRAM — measured llama.cpp flags, and a quantization finding. |
04 / STUDIO
A two-person studio based in Kocaeli, Türkiye. Small output, high care: narrow focus over broad promises. |
No account, no internet, one file. A desktop calendar for Windows with day, week and month views, recurring events, tasks you can drop onto the calendar, reminders, and .ics import and export. Built with Python + pywebview; your data lives in a local SQLite file. Interface in Turkish or English.
It's looking for its first real users. Try it and tell me what's missing or broken: open an issue, or read more on the product page.
| Topic | In short |
|---|---|
| Data | On your machine, in local SQLite, with a daily automatic backup and recovery if the file gets damaged. No account, no server. |
| Portability | .ics import and export, so you can move in from or out to other calendars. |
| Quality | 786 tests, CI on every push; every release is security-reviewed, smoke-tested as a built .exe and ships with build attestation (GitHub Actions). |

No account, no server. A desktop habit tracker: daily check-ins, a 30-day heat strip per habit, a Pomodoro focus timer, weekly tasks, mood tracking, a classic monthly grid view, and streak/completion stats — including a mood-to-completion correlation. Runs from the system tray, has keyboard shortcuts (Ctrl+1..4 tabs, Ctrl+N new habit), an optional start-at-login toggle, an evening reminder if you haven't checked in yet, and a daily automatic local backup. Built with Flutter; your data lives in a local SQLite database.

Your files, sorted into real folders. An Android app, designed for tablets and responsive on phones, that sorts PDFs, slides and documents into categories that are actual folders on the device. New downloads land in an inbox, categories nest, every file has a preview so you can recognize it even when its name says nothing, and there is undo plus a 30-day trash. Turkish interface, sideload-only APK, built with Flutter.
Early access. Checked in an Android 15 tablet emulator and on a real device with no problems so far; more testers on other devices are the point: open an issue or download the APK.
| Topic | In short |
|---|---|
| Data | Stays on your device. The app has no internet permission. |
| Install | APK from Releases; asks for Android's "all files access" so it can move files into folders. |
| Quality | 84 automated tests. |

Found and fixed two Windows installer/test bugs in avenoxbeyin that broke the V2→V3 upgrade and hid 23 test failures on Python 3.14 — both merged same-day. #119 · #126
Traced two blockers that left a failed update unrecoverable, each reported with a full trace. The first, a Windows/MSIX deadlock, the maintainer fixed upstream in v3.6.0 and credited the report. For the second, where recover died on a stale checksum after a note was edited, I wrote the fix and its regression tests — merged the same day.
#139 · #162 · #181 · #182
Reported an uninstall bug and a search-ranking gap measured on a real vault, then tested the contributed fixes against it on Windows. The tests caught that one fix would delete the user's own hook settings on uninstall, and that the new name boost also lifted generic-named archive notes; both were addressed before the fixes merged upstream. #353 · #354 · #355 · #357
