ChastiKey - Timed Keyholder stores and hides lock combinations for a set duration, turning your device into a digital keyholder that enforces waiting periods through card-draw mechanics. Running the app on a desktop computer lets you keep it open alongside other windows, maintain a persistent login session, and interact with lock timers and card draws using keyboard input instead of mobile touch controls. Whether you set fixed-duration locks or variable locks that shift based on daily card selections, moving ChastiKey - Timed Keyholder to Windows puts the full experience on your primary work machine.
ChastiKey - Timed Keyholder functions as a timed lock manager: you supply a combination to your physical lock or safe, the app hides it from view, and you retrieve it only after the timer expires or you unlock it through the in-app card game. On a PC, you can leave the application running in a persistent window while you work, check remaining lock time without mobile interruptions, and return to card-draw attempts at scheduled intervals without reaching for your phone.
How Lock Types Work
The app offers two lock modes. Fixed locks count down a set number of hours or days without variation. Variable locks shift their duration based on card outcomes: each day or hour, you draw from a shrinking deck where a green card reveals your combination, a red card extends the waiting period, and a yellow card adds or removes red cards from the deck. You can run multiple locks simultaneously, each with independent timers and card draws.
Setting Up and Managing Locks
When you create a lock, you choose the combination length (4 to 8 digits), maximum lockout duration, and whether the timer can increase or decrease by up to 50 percent. The app then generates a random combination for you to enter into your physical device, followed by a screen of flashing numbers to help you forget the code. ChastiKey - Timed Keyholder for Windows lets you keep these settings visible on your desktop, review lock parameters without switching between apps, and adjust or monitor multiple active locks from one persistent window.
Card Draw Mechanics
Variable locks rely on card selection to determine unlock eligibility. Once per day or hour (depending on your setup), you attempt to find a green card in a shuffled virtual deck. Each draw removes that card, improving your odds on the next attempt. This mechanic keeps progression tied to chance and regular check-ins rather than a simple countdown, adding an element of anticipation to the unlocking process.
Known Limitations and Stability
The app exhibits performance issues that affect the user experience. Loading screens appear frequently during lock setup and when checking remaining time, causing noticeable slowdowns. Background processes consume battery on mobile devices, though desktop use avoids this drain. Some users report crashes or app closures without warning, and account creation can stall during initial setup. A feature request from users involves additional solo options, such as skill-based mini-games to earn unlock attempts instead of relying solely on card draws.

FAQ
What happens if I write down the combination before the timer ends?
Writing down the combination defeats the security purpose of the app. The flashing-number screen is designed to help you forget the code so that waiting out the timer becomes the only way to access it. You may write it down during initial testing to familiarize yourself with the app's flow.
Can I run more than one lock at the same time?
Yes, ChastiKey - Timed Keyholder supports multiple locks running concurrently, each with its own timer, card deck, and settings. This allows you to manage different devices or safes on separate schedules.
How often do I get a chance to unlock a variable lock?
You draw one card per hour or day, depending on the settings you chose during setup. The draw removes that card from the deck, increasing your chances of selecting the green card on your next attempt.
Does the app work offline?
The app relies on online functionality for updates and account management. Users have noted that offline mode for certain features would improve performance and stability.
Is there a way to customize the combination format?
The app allows you to set the combination length between 4 and 8 digits. Some users have requested an option to exclude repeated digits for compatibility with devices that do not allow duplicate numbers in codes.
What should I know about performance before installing?
ChastiKey - Timed Keyholder PC version may experience loading delays, especially during setup and time-check screens. Desktop use avoids the battery drain reported on mobile devices, though the underlying performance issues persist across platforms.
