Frequently Asked Questions

The surest thing is to link your account on your current device before you switch. Sign in with Google from the settings screen, and then simply signing in with the same account on your new device will carry everything over.

Just in case, we also recommend saving a screenshot of the User ID shown at the bottom of the settings screen.

If you're playing as a guest, your data lives only on that device and is at real risk of being lost. Please link your account before changing devices.

In most cases the data hasn't been deleted — the signed-in account has simply changed. Try signing out of the current account first, then signing back in with the Google account you were originally using. That alone resolves it more often than not.

If your data still doesn't appear, please write to contact@dobby-canvas.com. Either one of the following lets us look it up on the server and help you recover it.

■ Your Google order number (starts with GPA., preferred if you've made a purchase) ■ The User ID you were using before (bottom of the settings screen)

One important request: after you contact us, please do not launch the app until we confirm the transfer is complete. Launching it can overwrite the server with your current empty data and make recovery difficult.

Your data hasn't disappeared — only the sign-in state was released. Sign out of the guest account and sign back in with your original Google account, and everything will be there.

If you try to link Google at this point you may see "This Google account is already registered." Don't worry — that message actually confirms your previous account is alive on our server. Please sign in rather than link.

Going forward, please avoid signing out or unlinking, and stay signed in with Google so this doesn't happen again.

We're sorry we didn't warn you about this in advance. It isn't a server error — it happens when data from two devices overwrites each other.

Game data is saved from your device to the server. If you leave one device in the background by only pressing the home button, that device is still holding older data and will later overwrite the server with it. That's why progress or currency you earned on the other device looks like it vanished.

You can prevent it by fully closing the game from the recent apps list when you finish playing on a device. Simply leaving via the home button keeps the app alive in the background and the same thing will keep happening.

Using the Delete Account menu destroys your data immediately, with no grace period. Progress, currency and purchase records cannot be recovered, so please decide carefully.

A deleted social account may also not be re-linkable right away.

The Dobby Canvas browser version uses Google sign-in.

If you signed in with the wrong Google account, sign out of the current one first, then sign back in with the account you want to use as your main.

Please do read this. It's the one thing that can't be undone.

For a guest account, "sign out" deletes the account itself. Signing in as a guest again starts you over from the first stage, and there's no way back to the previous account.

Purchases made while on a guest account do not come back after reinstalling, because the newly created account is a different account.

There's only one safeguard: link a Google or Apple account before you buy anything. Linking doesn't reset your progress, so there's nothing to worry about.

Once linked, reinstalling or changing devices only takes signing in with the same account to bring back your progress, coins and ad removal.

One account can only play on one device, so simultaneous sign-in is blocked. When you sign in on a new device, the device that was already connected is pushed out and the app closes. The absence of a retry button is intended.

If you want to continue on this device, simply sign in again — and this time the other side will be pushed out.

No heart is charged for a stage abandoned this way, so please don't worry.

If it feels like the app keeps closing on you, first check whether another device — or another family member — is signed in to the same account.

Open the settings popup from the home screen → Account Settings → tap Account ID to copy it. It's a 28-character value.

Including it when you contact us lets us find your account.

If you've linked a Google or Apple account, no recovery request is needed. After reinstalling or changing devices, signing in with the same account brings back your progress, coins and ad removal.

Guest accounts cannot be restored. We'd rather tell you this plainly than leave it vague.

We also don't move data to a different account, because purchase records belong to the account rather than the device. Thank you for understanding.

Deleted notes don't disappear right away — they're kept in the trash for 30 days. You can restore them yourself from the trash, so please check there first.

After 30 days the underlying files are deleted too and cannot be recovered. We're sorry.

Please do read this. It's the one thing that can't be undone.

Signing out of a guest account permanently deletes all your data, including notes and attachments, and you cannot sign back in. There is no recovery path.

Please link a Google account before you sign out. Once linked, the notes you wrote as a guest carry over intact.

If you're currently using a guest account, we strongly recommend linking right now.

You'll need to type "탈퇴" into the confirmation field in settings for it to proceed.

Your notes, recordings, attachments and conversation history are all permanently deleted immediately and cannot be recovered. Please decide carefully.

Currently, deleting a note also deletes its linked attachments and recordings, and your usage drops immediately.

However, there was a period when trash cleanup only ran when you signed in to the web app, so users who only used mobile may still have inflated usage figures. The server now runs the cleanup itself once a day.

If your usage looks different from reality, write to contact@dobby-canvas.com and we'll recalculate your account's actual usage.

This happens when the payment completes at the store but the app closes before it's applied in game.

First, close the app completely and launch it again. A pending payment often reprocesses at that point and the item arrives.

If it still doesn't, send your Google order number (starts with GPA.) to contact@dobby-canvas.com. We'll issue a full refund on the order number alone, with no review or conditions. If you'd rather have the item than a refund, we'll grant it directly — just let us know which you prefer.

The item hasn't been withdrawn, so please don't worry. There are two possible causes.

■ If it's a newly released item, the store (Google/Apple) is still approving the in-app product. Please allow one to three days.

■ If it's an item you normally buy without trouble, communication with the store failed and the product information couldn't be loaded. First check whether other prices in the shop display normally, then try: fully close and relaunch the app → switch between Wi-Fi and 5G/LTE → clear the Google Play Store app cache and restart your device.

If there's a record of a payment that didn't complete properly, Google Play sometimes blocks additional purchases of that same item for three to five days to prevent duplicate charges. Even for a daily-purchase item, it can look blocked after the reset time has passed.

This is a store-side restriction we can't lift ourselves, so you'll need to wait for it to clear automatically. We're sorry.

If you have an earlier payment that was never delivered, that's a separate matter — please contact us about it.

This happens when several Google accounts are connected to your device and the game calls up the one without a balance.

Tap your profile at the top right of the Play Store, switch to the account that has a balance, then clear the Google Play app cache in your device settings and restart.

If you were charged but didn't receive your item, we refund 100% in cash with no review or conditions. Send your Google order number (starts with GPA.) to contact@dobby-canvas.com and it will be processed within two to three days.

If you'd rather receive the item than a refund, we'll do that instead — just tell us which you prefer.

We're sorry. Regional sanctions block payment and ad communication entirely, so normal use isn't possible.

We're a small indie team and building a separate payment module for this isn't realistically within our means. Thank you for understanding.

There are two products with different purposes, and they're easy to confuse. Please check which one you purchased.

■ Forced Ad Removal — permanently removes only the full-screen ads that appear automatically between stages. One purchase per account ■ Reward Ad Removal — 100 tickets, each of which can substitute for one rewarded ad. Consumable, and can be purchased repeatedly

Neither removes all ads. Even with Forced Ad Removal, the rewarded ads you choose to watch yourself remain. If our product descriptions weren't clear enough about this, we're sorry.

Tickets are never consumed automatically. Each time, a popup asks whether you want to use one.

First, close the app completely and open it again. When the app can't reach our server, the store keeps resending the incomplete purchase, so relaunching usually delivers it.

This is especially true if you saw the message "Your purchase may not have completed." The receipt stays on your device and is applied on the next launch.

If it still doesn't arrive, send us both your account ID and your order number (the GPA. number in your Play purchase email) at contact@dobby-canvas.com. We need both values to look it up.

Forced Ad Removal is a one-per-account product, so the store won't allow a second purchase. On Android the payment sheet simply won't open.

Waiting won't change this. Signing in with the account you originally bought it on will let you use it, so please sign in with that account.

If you can't remember which account you used, contact us with your order number.

Coins you've already spent are not clawed back. When a refund is processed we deduct only what's left and stop at a balance of zero. For example, if you received 1,500 coins, spent 1,200 and then refunded, only the remaining 300 disappear.

If you disputed a refund with Apple and it was reversed, items are not automatically re-granted. If your dispute was accepted but your items haven't come back, please do contact us — we'll grant them again ourselves.

Four things differ.

■ Monthly AI budget — Free $1.00 / Pro $10.00 ■ Storage — Free 10 MB / Pro 5 GB ■ Maximum length per recording — Free 5 minutes / Pro 2 hours ■ Chatbot note search — Free refers to your 5 most recent notes only / Pro searches all notes semantically

Pro is $9.99 per month. New sign-ups start on the Free plan; there's no free trial period.

We'd rather be straightforward about this. The amount shown isn't the raw cost of the AI model — it includes app store fees and the real cost of running our servers. As a small indie team we can't keep the service alive without covering that, which is how the figure is set.

Usage is counted in UTC. The monthly limit sums your spend from the 1st of the month on the UTC calendar, so in your local time the reset point can appear to be off by a day late at month's end.

You can see a chart of your last 14 days of usage in settings and on the dashboard. A warning banner appears at 80% of your limit, and AI features lock at 100%.

Extra credits aren't a balance — they raise your monthly limit. Whatever you purchase is added on top of it.

They don't reset each month, so they aren't something you use up and lose within the month. If you need a definitive answer on validity, please write to contact@dobby-canvas.com and we'll confirm it precisely for you.

When you refund, the credited amount is reclaimed, and whatever you've already used is settled against your next top-up.

Because of that, refunding after using a substantial portion of your credits may leave you unable to use AI features for a while. Please keep this in mind before requesting a refund.

If AI features stop working entirely after a refund, write to contact@dobby-canvas.com and we'll check the state of your account.

This banner appears when a recurring payment fails at the store. Please check your registered payment method first — an expired card, or an insufficient limit or balance, accounts for most cases.

Once payment goes through normally, the banner disappears on its own.

We're sorry for the trouble. If the app force-closes while an ad is playing, the "watch complete" signal never reaches our server, so the reward isn't applied. An unstable network connection can cause the same thing.

If the app closes on you often, please clear background apps, turn on low-resolution mode in settings, and restart your device once.

If it keeps happening, please send us a screen recording that covers everything from the start of the ad to returning to the game screen without the reward. Including the time it happened, your User ID and your device model helps us a great deal.

Ads in our games are served through Google AdMob. Google — not us — decides which devices receive ads, so when Google restricts delivery there's no way for us to force one to display.

Google sometimes declines to supply ads based on a device's specs or usage environment, and the criteria aren't disclosed to us. If you use a VPN, an ad blocker or a security filtering app, that may also be a factor.

Could you check whether your device has any apps that advertise themselves as "optimizers" or "cleaners", or security-type apps? When these run constantly they slow the app down and also make it harder to receive ads from Google. If something comes to mind, try stopping or removing it and playing again. We can't say for certain, but of the things you can try right now this has the best odds.

We don't create these ads ourselves — Google AdMob receives them from advertisers and displays them — so some ads hide the close button or place it where it's hard to find. We're sorry for the frustration.

If you'd rather play without ads, please take a look at the remove-ads option in the app.

Ignoring it is the right answer. Please never tap it and never install the app it points to. These are almost always fake ads designed to provoke anxiety and push unnecessary installs.

Ads are served through Google AdMob, so we can't select individual ads ourselves. We're sorry you had this experience.

If you send a screenshot of the ad to contact@dobby-canvas.com, we'll report it to AdMob and have it blocked. If you'd prefer to play without ads, the in-app remove-ads option is also worth a look.

This isn't a bug — it's intended. The cooldown isn't applied per reward type but to "having watched an ad", so whichever free ad you watch, the same cooldown applies to the others.

Watching ads back to back in quick succession causes ad rates to collapse, and ad revenue converges to nearly zero. A small team can't keep the service running without a basic gap between views, so this is how we designed it. We'd rather be honest with you about the reason.

Once the cooldown passes, any remaining free rewards are still yours — nothing is lost. We'll pass along the request to separate the ads, but for the reason above we can't promise full separation.

The amount credited isn't a fixed figure — it's exactly what that ad actually earned. It's usually between $0.02 and $0.15.

On iOS, if you haven't allowed app tracking, ad rates drop sharply to roughly $0.005 to $0.02. Allowing tracking in settings will raise your rewards.

For reference, this app has no banner or interstitial ads — just the one rewarded ad you choose to watch.

This usually points to insufficient memory. Please try the following in order.

■ Clear all other apps running in the background ■ Turn on low-resolution mode in settings (important) ■ Avoid playing while charging

Low-resolution mode lowers the resolution of the images we load to keep memory use as low as possible — it was added specifically for this problem. Reducing it further would mean rebuilding the game's visuals and content from scratch, which isn't realistic at our size. We're sorry we can't give you a comfortable experience on your device.

This is almost always a network issue. Please try the following in order.

■ Turn Wi-Fi off completely, switch to 5G/LTE mobile data, and retry ■ Close the app fully and relaunch it ■ Clear the cache in device settings > apps, then retry

Shared Wi-Fi often blocks server access through its firewall, so switching to mobile data tends to be the most effective step.

Including the items below helps us find the cause far faster. Thank you for taking the time to report it.

■ Your device model and RAM capacity (essential for telling whether low memory is the cause) ■ Your User ID (bottom of the settings screen) ■ A screenshot or screen recording of the problem ■ Where and when it happened

Please send it to contact@dobby-canvas.com.

No. Our services have no planned shutdown and will continue to operate. Please rest assured.

What you saw is a notice Google sent to all Android users, about replacing Google Assistant on mobile devices with Gemini. It has nothing to do with the game and no effect on how it works.

The name Gemini also appears in the game's AI conversations, which makes this easy to confuse — but what the game uses is a developer API, entirely separate from the assistant app being replaced.

In August 2026 there was a period when a server-side configuration error stopped notifications from going out. That was our fault, and thanks to a user report we found it and restored it immediately. It's working normally now.

The reason deleting and reinstalling the app didn't help is that the cause was on the server, not on your device. We're sorry you went to that trouble for nothing.

If you still haven't received notifications for several days, please check your device's notification permissions, and let us know again if that doesn't resolve it.

The absence of a retry button is normal. Tapping OK returns the app to its first screen, and that return is itself the retry.

The same applies when "Failed to load the app" appears and the app closes — reopening it is the retry.

This game requires a network connection and doesn't support offline play. If your connection keeps cutting in and out, check switching between Wi-Fi and mobile data, whether a VPN is in use, and whether your device clock is accurate.

No. There is no penalty of any kind in game, and it isn't a problem with your device or account. The AI model's own safety policy stopped the response from being generated. Please don't worry.

Two things are worth trying.

■ Change the AI model to ChatGPT or Claude in settings. Each model has different safety thresholds, and conversations blocked on Gemini often continue normally on another.

■ Delete the conversation that seems to have triggered it. Gemini judges based on the entire conversation flow up to that point, so as long as the flagged exchange remains, any message you send afterwards will keep getting cut off. Deleting that section — or the whole conversation history — usually resets the flow and restores normal behaviour.

Any tickets lost in the process will be fully compensated, so please get in touch.

One more thing: our team doesn't individually judge the tone of character conversations. Each AI model decides automatically according to its own policy.

Speed varies a lot by model.

■ Gemini gives deeper, richer conversations, but once the history builds up, delays of 10 to 30 seconds are common ■ ChatGPT is usually well under 5 seconds

If the wait bothers you, try switching to ChatGPT in settings. You should feel the difference immediately.

This isn't a problem with your account or your data, so please don't worry. It's an occasional issue on Google Gemini's side — when usage spikes, Google's servers sometimes malfunction briefly and repeat the same characters.

Waiting a little and trying again usually restores normal behaviour. If it persists across several attempts, please send us the time it happened along with a screenshot.

They're produced with an AI voice generation model. As a small indie team, preparing recorded voice acting for every character across all supported languages isn't realistically within our means, so we chose this approach.

Because of that, some intonation or pronunciation may sound unnatural. We're continuing to refine it, so please let us know when you come across a line that sounds off.

This isn't a bug — it's a plan difference.

On the Free plan semantic search is off, and only your 5 most recent notes enter the chatbot's context. So the more notes you have, the more often it says it doesn't know when you ask about older ones.

Upgrading to Pro enables semantic search across all your notes, which finds older ones too.

Booster mode is most likely turned on. Look for the purple lightning button and tap it to turn it off.

While booster mode is on, lower-tier items aren't generated. Turning it off brings them back immediately.

Yes, there's a maximum. Once you reach it, affection stops increasing.

If you used an affection item and it seems stuck at 0%, that's normal behaviour when you've already reached the cap.

Yes. You can choose between male and female, and the first change is free.

If you only log in repeatedly without generating images or engaging with the social feed, login rewards gradually decrease.

Creating an image or taking part in sharing activity, even a little, will earn you larger rewards.

You have up to 5 base hearts, and one refills naturally every hour.

Entering a new stage is free. There are only three places a heart is spent.

■ When you fail because the time limit ran out — 1 ■ When you manually retry a stage in progress — 1 ■ When you leave a stage in progress and return home — 1

If you never moved a single item, leaving or retrying costs nothing. However, a stage where you simply let the time run out counts as played to the end, so 1 heart is spent.

If the app closes while a stage is open, that stage counts as abandoned and the cost is settled on your next launch. That's why you sometimes open the app to find one fewer heart.

Refills via ads or tickets are limited to 5 per day (UTC), one heart each.

It's normal, and not a bug, so please don't worry.

Base hearts cap at 5, but hearts you receive from ads, tickets or purchases are "extra hearts" and have no cap, which is why you can see 6 or more. When hearts are spent, extra hearts are always used first.

Absolutely. We welcome and encourage all non-commercial derivative work, including pieces made with AI tools.

Making personal-use goods (acrylic stands, plushies and so on) based on images or illustrations you obtained in game also falls within non-commercial derivative work.

If you post your finished work on X (Twitter) or elsewhere, send us the link. We'd be glad to repost it from our official account so others can see it too.

Thank you — genuinely. At our team's size we miss a lot, and reports like this help enormously.

If you'd like to help fix in-app typos directly, write to contact@dobby-canvas.com. We grant access to a dedicated system, and when your corrections are applied we send 2,000 diamonds as thanks.

The judgement considers not only how revealing the clothing is but the situation and background as a whole, and it's based on the generated image itself rather than on your intent. When you leave generation to the AI, results can come out more revealing than you intended — specifying clothing concretely in your prompt makes the output considerably more stable.

There are two exceptional cases.

■ If you delete a large number of posts in a short period, the system may read that as a suspicious signal and apply R-18 to your subsequent posts ■ If a third party mass-reports posts at random, several users' posts can be flagged together. In that case we review them manually and lift the flag

If you believe your post was misjudged, send us the post URL at contact@dobby-canvas.com and we'll check it ourselves.

Yes — the service closed at the end of August 2026.

Thank you sincerely for using it. We concluded that continuing it wasn't sustainable at our team's size. We're sorry it ended this way, and we'll remember the support you gave it for a long time.

If you have any questions related to this, please write to contact@dobby-canvas.com.
