Mokusai ("we," "our," or "us") respects your privacy and is committed to protecting your personal information. This Privacy Policy explains how we collect, use, store, and protect information when you use the Mokusai mobile application.
By using Mokusai, you agree to the practices described in this Privacy Policy.
Mokusai does not require account registration to use the core features of the app. We do not require your name, email address, or other personal identifiers for normal usage.
Photos, bonsai designs, notes, logs, and related content you create in the app are primarily stored locally on your device.
We do not upload your bonsai photos or personal design files to our servers unless a future feature specifically requires cloud backup or syncing, and you choose to use it.
We may collect limited non-personal technical information, such as:
Device model
Operating system version
App version
Crash reports
Performance diagnostics
General usage analytics
This data helps us improve app stability and performance.
Mokusai may request the following permissions:
Used to take photos of your bonsai trees for styling, timeline history, and care records.
Used to select existing images from your device.
Used to save project files, exported images, and local backups.
You can manage permissions anytime through your device settings.
We use collected information to:
Provide and operate app features
Save and manage your bonsai projects
Improve app performance and reliability
Fix crashes and bugs
Deliver customer support
Process purchases and subscriptions
Mokusai may use trusted third-party services that may collect data according to their own privacy policies.
These may include:
Google Play Services
Google AdMob (for ads)
Google Play Billing (for subscriptions and in-app purchases)
Analytics or crash reporting providers (if enabled)
We recommend reviewing their privacy policies separately.
The free version of Mokusai may display advertisements through third-party advertising partners such as AdMob.
These providers may use device identifiers or similar technologies to show relevant ads, subject to applicable laws and your device settings.
Mokusai may offer premium features, subscriptions, or one-time purchases processed securely through Google Play Billing. We do not store your payment card information.
Most user-created content is stored locally on your device.
We use reasonable safeguards to protect information, but no method of storage or transmission is completely secure. We recommend:
Keeping your device updated
Using screen lock security
Backing up important files regularly
Mokusai is not intended for children under 13 years of age (or the minimum age required in your country).
We do not knowingly collect personal data from children.
If you believe a child has provided personal information, please contact us so we can take appropriate action.
Depending on your region, you may have rights regarding your personal data, including:
Access to your data
Deletion requests
Restrict certain processing
Withdraw consent for ads personalization through device settings
Because most data is stored locally, you may also delete data directly by uninstalling the app or clearing app storage.
We may update this Privacy Policy from time to time.
When changes are made, we will revise the “Last Updated” date. Continued use of the app after updates means you accept the revised policy.
If you have any questions or concerns regarding this Privacy Policy, please contact us through the support section inside the Mokusai app.
