Privacy Policy
In short: Mochi Color turns photos into coloring pictures on your device. It does not upload your photos, your artwork or anything else to the developer. The app has no accounts, no advertising, no tracking and no analytics SDKs. Purchases are handled by Apple.
Mochi Color is published by Kunio Shimizu, an individual developer based in Tokyo, Japan ("the developer", "I"). Questions about privacy: mochicolor.app@gmail.com.
1. Photos and camera
Mochi Color converts photos into numbered coloring pictures on your device. It does not upload your source photos, camera images or artworks to the developer or to any server operated for the app.
Photo uses Apple's photo picker, so the app only receives the single image you select and does not browse your photo library. Camera asks for camera permission when you choose to take a photo. You can cancel either flow and use the built-in designs instead. The app does not access your microphone or your location, and it does not save camera captures to your photo library.
The image you choose is used while a coloring picture is created. A canceled conversion may keep its temporary input until the processing task finishes. Saved artwork contains the derived color grid, palette, creation date, progress and paint order rather than the original photo file or its EXIF metadata. The derived picture can still show the subject of your photo.
When you tap Save to Photos, Mochi Color asks for add-only permission and saves a clean image of your finished picture to your photo library. It does not read or browse the library. Saved images are then handled by Apple's Photos and iCloud services according to your settings. Deleting an artwork in Mochi Color does not remove a copy you saved to Photos.
2. What is stored on your device
The following is stored only on the device you use, inside the app's own storage:
- Your artworks, including progress and paint order, and the creation date of each one
- The last-opened picture
- Sound, music, mute and bubble vibration settings
- A record of how many free photo creations have been used on this device (see section 3)
The app does not sync artworks between devices. The app's data is included in normal device backups (iCloud Backup or a computer backup) under the settings you control on your device; the developer has no access to those backups.
To delete pictures, use Select in In Progress or Finished, choose the pictures and tap the trash button. Deleting the app removes its local artworks, settings and free-use record. Offloading the app keeps its data. Removing Mochi Color does not delete images you saved to Photos and does not erase existing device backups; those are managed through Apple's services and your device settings.
3. Purchases and restoring
Photo and Camera share a combined allowance of three free creations per device. Only successfully created and saved pictures use the allowance. Opening a preview, comparing levels or canceling does not. Built-in designs and painting an existing picture again never use it. Deleting pictures does not restore used free creations. This record is stored on your device, separately from your artworks, and is not sent to the developer or synced by the app.
A one-time, non-consumable Apple In-App Purchase unlocks unlimited photo and camera creations. Apple handles payment through the App Store under Apple's own terms and privacy policy. Mochi Color uses Apple's StoreKit framework to verify the purchase entitlement on the device. The app does not collect payment card details, and it does not require an account operated by the developer.
Restore purchases asks Apple to check a previous purchase made with the same Apple Account; Apple may ask you to sign in. Family Sharing is not offered for this purchase. Unlimited access depends on a valid purchase entitlement; a refunded or revoked purchase no longer grants it. Your existing pictures, the built-in designs, replay and saving to Photos remain available without the purchase.
A grown-up check (a small arithmetic question) appears before the purchase screen. It only asks for an answer and stores nothing.
4. Data sharing and measurement
The app contains no developer-operated accounts, advertising, tracking or analytics SDKs, and it does not send usage events, crash reports or any other data to the developer. It makes no network requests of its own; the only network activity is Apple's StoreKit communicating with the App Store for the purchase and for restoring it.
Apple may process App Store activity, purchase records, and (if you have opted in on your device) diagnostics and usage information under Apple's privacy policy. The developer sees only the aggregated, anonymized reports that Apple provides to all developers in App Store Connect, such as download counts, sales and crash statistics. These reports do not identify you to the developer.
The developer does not sell, rent or share personal data, because the app does not collect any.
5. Permissions and your choices
- Camera: requested only when you choose Camera. You can change it anytime in your device's Settings under Mochi Color.
- Add to Photos: requested only when you tap Save to Photos. Also changeable in Settings.
- Photo picker: uses Apple's system picker, which needs no standing permission.
You can cancel photo selection or camera capture at any point. The built-in designs stay fully usable if you never grant either permission.
6. Children
Mochi Color is made for families and collects no personal information from anyone, including children. There are no accounts, chats, links to social media or advertising inside the app. A grown-up check sits in front of the purchase screen, and purchases themselves are completed through Apple's App Store, which may require the Apple Account password or Face ID and supports Apple's Ask to Buy.
7. Support email
If you contact support by email, your email address and the content of your message are received by the developer and handled by the email provider used for that mailbox. The information is used only to answer your request and is kept only as long as needed for that purpose. Please do not send children's photos, saved artwork files or other personal information that is not needed to resolve your question.
8. This website
This website (mochi-color.sren.workers.dev) is a static site hosted on Cloudflare Workers. Cloudflare, Inc. delivers the pages and, as part of operating its network, processes connection data such as your IP address and request headers under the Cloudflare Privacy Policy. The site sets no cookies of its own, has no forms and no login.
The site uses Cloudflare Web Analytics to count page views. It does not use cookies or local storage, does not fingerprint devices and does not track you across other sites. The developer sees only aggregate statistics such as page views, countries and browser types.
9. Changes to this policy
This policy will be updated if the app's or the website's data practices change. The date at the top identifies the current version. A copy of the app's privacy summary is also available inside the app under Settings › Privacy policy, so it can be read without an internet connection.
