Support

If you run into trouble with any app published under kuroneko-cmd.dev, this page is the best place to start. It explains how to reach me and what details make it easier to understand and fix problems. Each app also has a short note with a few tips before you email.

How to reach me

• Email: contact@kuroneko-cmd.dev
• I will get back to you as soon as I can.

To help me see what is going on, it is helpful if you can include:

• Which app you are using (for example, Simple Warm Reminder).
• Device model and OS version.
• App version (shown in the App Store or inside the app, if available).
• A brief description of what you were doing and, if possible, screenshots or a short screen recording.

App-specific notes

Simple Warm Reminder

Simple Warm Reminder 3.3 is available on the App Store. These instructions describe 3.3; items marked “from 3.3” need the update.

• Requirements: iPhone or iPad with iOS 18.0 or later. The app works offline, with no account or cloud sync. All features are free; the Tip Jar is optional and unlocks nothing.
• Set a reminder: Hold one of the four large buttons. Turn off stove starts a countdown timer. The other three are daily reminders by default. Hold the button again to cancel it, or hold Cancel All at the bottom to clear everything.
• Medication times: Open Settings → Change Reminder Times & Names to rename a button, switch it between In a few minutes (a timer) and Every day, and turn on up to three times a day (morning, noon, evening).
• Set Up for Family (from 3.3): On your own phone, set the names and times first, then open Settings → Set Up for Family and choose which daily reminders should be on for them. Your family member installs the app, scans the QR code with the iPhone Camera, checks the list, and taps Import. Importing replaces the four reminders on that phone; your own reminders do not change. Voice recordings are not shared, so they will hear the default sound until a recording is made on their phone.
• The link does not open: Links sent with Send as Link may not open inside some chat apps. Scan the QR code instead. If the app says the link is damaged, create the code again; if it says the link was made with a newer version, update the app on the receiving phone first.
• Answer from the notification (from 3.3): On the Lock Screen, swipe the notification left and tap View, or press and hold it, to see Done (shown as Medicine taken and similar for the default names) and Remind me in 10 min. Neither action opens the app.
• Reminders are not ringing: Allow notifications and Time Sensitive notifications for the app in iOS Settings, check the volume and the silent switch, and check Focus modes. The app asks for notification permission the first time you set a reminder or import a setup. Reminders are local notifications, and iOS may delay them after a long time in Low Power Mode.
• Remind Again If Missed: Turn it on in Settings to ring again 5 and 10 minutes after a reminder, until it is confirmed.
• Your own voice: Open Settings → Voice Ringtones and allow the microphone to record a reminder up to about 30 seconds long. Use the buttons under each recording to preview it, set it as the ringtone, rename it, or delete it. Recordings stay on the device.
• Appearance and language: Settings → Background & Dark Mode sets light, dark, or system appearance; the background choices apply in light mode. Settings → Change Language offers 22 languages and Follow System (from 3.3).
• Widget and Lock Screen countdown: Add the widget from the Home Screen’s edit mode. The Lock Screen and Dynamic Island countdown appears for timer reminders when Live Activities are allowed for the app in iOS Settings.
• Simple Warm Reminder is a reminder tool. It is not a medical device and does not provide medical advice; follow your doctor or pharmacist for what to take and when.

See the Simple Warm Reminder product page and privacy policy for more details. When reporting a problem, include your device model, iOS version, the app version shown in the App Store, the app language, and the steps that led to it.

KeepFlame

KeepFlame 2.0 is available on the App Store. These instructions describe version 2.0.

• Requirements: KeepFlame 2.0 runs on iPhone with iOS 26 or later. It works offline, with no account or cloud sync. All current features and the included 22-card collection are free.
• Upgrading from 1.1: Version 2.0 starts with new data. Your earlier habits and completion records are not imported and cannot be viewed in 2.0. Save screenshots or notes before updating if you need a record of them. Data already created in 2.0 continues to be used normally. There is no account-based recovery or developer-operated backup.
• Complete a habit: Long-press its row on Today. Keep one-off tasks in To-dos; a recurring to-do can be converted into a habit. Open Settings → Manage Habits to manage your routine.
• Earn Ember: Complete all of today’s scheduled habits to receive 10 Ember once that day. Every seven consecutive perfect days adds another 10. You receive 10 Ember for your first draw. To-dos and backfilled days do not earn Ember, and unchecking then completing a habit again does not grant the daily reward twice. The rules are in Settings → Draws & Ember.
• Draw and collect: Each draw costs 10 Ember and gives you a card you do not own. The current series has 22 cards. Once you have them all, you can keep the collection or use Settings → Current series → Start over. Starting over clears the cards owned in that series and keeps draw history and statistics. Read the confirmation before continuing. Cards and Ember cannot be purchased, traded, or redeemed, and the app does not provide tarot readings.
• Share a card: Open Collection, choose a card, and tap Share to use the iOS share sheet. You choose where the card image goes.
• Reminders: Set a reminder for an individual habit when creating or editing it. Use Settings → Notifications to enable or change the Daily Summary. Turning off the summary keeps individual habit reminders. Allow notifications when iOS asks, and open the app regularly to keep upcoming reminders scheduled. If reminders do not appear, check KeepFlame’s iOS notification permission and Focus settings. The Daily Summary is sent only when habits remain unfinished. To-do defaults and the period for keeping completed items in the list are under Settings → To-do settings. After that period, completed items are archived and hidden from the active list; they remain stored locally.
• Live Activities: Turn on Settings → Enable Live Activities, and allow Live Activities for KeepFlame in iOS Settings. Use Settings → Live Activities to display two to five items. Dynamic Island appears only on supported iPhones; the Lock Screen presentation is also available.
• Language: Choose Settings → Language for 22 language options or Follow System. The selected language also applies to reminders and Live Activities.
• Previous Pro purchases: The old one-time Pro purchase and monthly subscription have been retired and are no longer available to buy. The old monthly subscription will not renew. Version 2.0 removes the animation themes and Pro system and has no purchase or Restore Purchases button. You can check an earlier subscription under iOS Settings → your name → Subscriptions. For an earlier charge, follow Apple’s refund instructions. Apple handles refund requests and decides eligibility; approval is not guaranteed. For questions about a previous purchase, email contact@kuroneko-cmd.dev with the product name and approximate purchase date; do not send payment-card details.

See the KeepFlame product page and privacy policy for more details. When reporting a problem, include the app version from Settings → Version, your iPhone model, iOS version, selected app language, and the steps that led to it.

TravelBrain

• TravelBrain 2.0 requires iOS 26 or later and supports both iPhone and iPad.
• TravelBrain is an offline-first travel planner where you collect ideas in an Inbox, review their details, and arrange them on a timeline.
• Smart Import: Choose Inbox → + to take a photo, choose a photo, paste supported content, or enter details manually. You can also share supported content to TravelBrain from another app; it will wait in the main app for review.
• Recognition results look incomplete or incorrect: Text recognition runs on your device and provides editable suggestions, not guaranteed facts. Compare the result with the source, correct or clear any field, then save. For better results, use a sharp, well-lit image cropped to the relevant travel details. Low contrast and complicated tables can still produce omissions or mismatches, and recognition quality will continue to improve in future updates.
• Camera is unavailable: Camera import requires a supported physical device. If access was denied, open iOS Settings and allow Camera access for TravelBrain. Photo import uses Apple’s system photo picker.
• Shared content is not in a trip yet: The Share Extension deliberately creates a pending review item. Open TravelBrain, select the waiting import, review its fields, and save it to the Inbox or an eligible trip day.
• Appearance: Choose Settings → Appearance → System, Light, or Dark. System follows the current device appearance.
• All travel data and recognition processing stay on your device unless you explicitly export, share, or create a backup. We do not collect or transmit your travel plans.
• Backup & Restore: Export a backup manually through the system document picker to iCloud Drive, Files, or another location you choose. We have no access to the backup. Review the restore summary carefully before confirming.
• If notifications or Live Activities are not appearing, please check that TravelBrain is allowed to send notifications in iOS Settings.
• TravelBrain Pro (Lifetime): This is an optional one-time purchase, not a subscription. It unlocks long-image and JSON exports. Restore a previous purchase from Settings → TravelBrain Pro → Restore Purchases.

TalkMirror

• TalkMirror is designed to run offline. Your practice audio is processed in memory for immediate playback and is not saved as audio files.
• If Voice Mirror does not start, please make sure TalkMirror has microphone permission in iOS Settings.
• For safety, TalkMirror pauses when the app goes to the background or the screen locks, and it will not auto‑resume when you return.
• From version 2.0, putting on or taking off headphones or AirPods does not stop a session: audio moves to the new device and a short notice appears. Calls and other interruptions still pause practice until you tap Resume. If the microphone cannot restart after a device change, TalkMirror pauses and tells you so.
• On the built-in speaker, Shadow Read waits about a second after the reference voice before it listens again, so start speaking when “Listening” appears. Headphones give the cleanest result.
• If Shadow Read sounds silent or the reference voice is missing, choose another Apple system voice in TalkMirror and make sure that voice is downloaded in iOS Settings.
• To switch between the free built-in sentence library and your own text, tap the Practice Material bar at the top of Shadow Read. The library is included with the app and does not require a separate download.
• To change the look, tap the palette button next to the TalkMirror title on the home screen, or open Settings → Appearance → Theme. Spotlight and Night Radio are always dark, so the Light/Dark choice is paused while one of them is selected. In Pixel Arcade, tap the arrows under the character in Voice Mirror to switch companions.
• The short finish after a practice can be turned off in Settings → Appearance (animation) and Settings → Audio Settings (sound and haptics).
• TalkMirror runs natively on iPad from version 2.0; in a narrow Split View window it uses the iPhone layout.
• Practice reminders are optional and off by default. Enable them from TalkMirror Settings, then allow notifications when iOS asks. If reminders do not appear, check the app’s notification permission in iOS Settings.
• When reporting an issue, it helps to include the mode you were using, whether Bluetooth/headphones were connected, and your device + iOS version.

SentenceDeck

SentenceDeck 2.0 is available on the App Store (released October 7, 2026). These notes describe 2.0; version 1.5 has Read Along only and the earlier menu names (for example Backup & Export).

• 2.0 launch gift: From October 7 to November 6, 2026 (UTC), opening SentenceDeck 2.0 adds free characters to your wallet once per Apple Account: 6,000 characters if your Apple Account already had a SentenceDeck character wallet before 2.0 was released (for example, you used premium voice or opened Characters & Purchases in an earlier version), or 2,000 characters otherwise. You need an internet connection when you open the app. Characters you receive never expire.
• SentenceDeck 2.0 has three practice modes on its title screen: Scene Dialogues (30 everyday scenes at A2, B1, or B2), Describe Your Scene (a dialogue for a situation you describe), and Read Along (sentence-by-sentence shadowing of your own text).
• Where Settings is: tap the coral bookmark on the title screen. Settings → Replay Intro plays the animated introduction again.
• Standard dialogues are free, up to 10 new dialogues per day. The count resets at 00:00 UTC, which may be during your daytime depending on where you live. Dialogues you have already saved can be practiced again at any time without counting.
• Detailed dialogues use 200 characters each. The cost is shown before you start. Nothing is charged if generation fails, and opening a dialogue that is already saved does not charge again. Your wallet history shows each charge.
• Offline scenes: The 21 built-in English scenes at B1 marked Works offline include their audio and need no connection or characters. New dialogues, custom scenes, and premium voice need an internet connection.
• Describe Your Scene: Write one sentence (up to 200 characters) about an everyday situation. The first time, SentenceDeck asks for your agreement before sending the description through our server to Google Cloud’s AI service; the description is not stored. Descriptions with web addresses, email addresses, or phone numbers are refused, so leave out names and contact details. To withdraw your agreement, open Settings → Generation and tap Withdraw Consent; you will be asked again before your next custom scene.
• Reporting a dialogue: If an AI-written dialogue is wrong, odd, or inappropriate, tap the flag on the stage, or Report this dialogue on the recap after a scene. A report sends the dialogue’s ID and the reason you choose, not the dialogue text.
• Premium voice is unavailable: Check your internet connection, then open Settings → Characters & Purchases. If the balance or catalog is missing, sign in to Media & Purchases in iOS Settings and use Restore & Sync. SentenceDeck 2.0 asks once more for your agreement before the first premium request, even if you agreed in 1.5, because premium voice now uses Google Cloud’s AI speech service.
• A purchase succeeded but characters are missing: Open Settings → Characters & Purchases → Restore & Sync with the same Apple Account used for the purchase. Characters are tied to the purchase identity; there is no separate SentenceDeck login. If the balance still does not update, include the pack name, approximate purchase time, and App Store region when you contact support. Do not email payment-card details.
• System voice sounds robotic or silent: Choose another System voice in SentenceDeck and make sure the voice is downloaded under iOS Settings → Accessibility → Spoken Content → Voices. System voice is free, offline, and does not use characters.
• Why did a sentence use characters again? Cached premium audio replays without another charge only while the sentence, voice, style, and generation settings still match. Changing a premium voice or style may require new audio and consume characters.
• Playback speed: Changing practice playback speed from 0.75× to 1.5× does not regenerate audio or consume more characters.
• Device backup: Premium audio is eligible for iCloud or computer device backup only while backup is enabled and has enough space. It returns as part of a full device restore; deleting and reinstalling SentenceDeck alone does not restore it. Free System-voice audio can be generated again and may be excluded from backup.
• Saving a backup: Open Settings → Backup & Restore (called Backup & Export before 2.0) to create one SentenceDeck ZIP with your scenes and articles and their generated audio. Creating a backup does not generate audio or use characters. A merged audio file from an Export menu is for listening and cannot be imported as a backup.
• Restoring a ZIP: In Backup & Restore, tap Import Backup and choose a SentenceDeck ZIP; you see what it holds before anything is imported. Matching articles are updated and other compatible articles are created. Audio using a different voice, style, or generation configuration may be skipped to avoid attaching the wrong sound. Restoring does not generate audio or use characters.
• What an audio ZIP does not restore: Practice progress is not included. Keep the original ZIP until you have checked the restored scenes, articles, and audio.
• SentenceDeck does not run its own audio-sync service. Generated audio stays on your device unless you explicitly export or share it.
• When reporting a problem, include the mode (Scene Dialogues, Describe Your Scene, or Read Along), the voice type (System or Premium), the practice language, device model, iOS version, SentenceDeck version, and the exact message shown. Do not include private text unless it is necessary and you are comfortable sharing it.

SugarCurfew

• SugarCurfew is a privacy-first sugar logging app for drinks, desserts, and packaged foods.
• The app works without accounts, ads, analytics SDKs, tracking, or cloud sync.
• Photo Add uses on-device processing. Photos and OCR text are not uploaded to a third-party AI service or cloud server for recognition.
• If camera access is not working, please check iOS Settings and allow camera permission for SugarCurfew.
• If a photo result looks wrong, edit the category, item name, or sugar amount before confirming. SugarCurfew is designed as a confirmation flow, not a silent auto-log.
• Manual backup files are created only when you choose to export them and do not include photos.
• SugarCurfew is not a medical device and does not provide medical advice, diagnosis, treatment, or professional nutrition guidance.
• When reporting an issue, it helps to include your device model, iOS version, app version if available, and a brief description of what you were trying to log.

HushVault

• HushVault is a private, offline app for remembering where you put important things at home and finding them again later.
• The app works without accounts, ads, analytics SDKs, tracking, or cloud sync. All photos and records stay on your device.
• Take a photo of where an item is stored, or import one from your photo library. If camera or photo access is not working, please check iOS Settings and allow the relevant permission for HushVault.
• Reminders not appearing? Optional re-verification reminders are off by default. Turn them on per item, and make sure HushVault is allowed to send notifications in iOS Settings. Notifications are intentionally low-exposure and never show your titles, locations, tags, or photos.
• App Lock: You can manually lock the app; unlocking uses Face ID / Touch ID and falls back to your device passcode. Content is blurred when the app is in the background.
• Backup & Restore: Backups are a single password-protected file created only when you export them. Keep the backup password safe — it is required to restore, and we cannot recover it for you.
• When reporting an issue, it helps to include your device model, iOS version, app version if available, and a brief description of what you were doing.
