Terms of Service
Last updated: September 20, 2026
CleanSketch (“we,” “our,” or “us”) provides the mobile application “CleanSketch” (the “App”). Please read these Terms before using the App.
1. Acceptance
By using the App, you agree to these Terms. If you do not agree, do not use the App.
2. Eligibility
You must be at least 13 years old to use the App.
3. Account
Some features require Google Sign-In. You are responsible for activity under your account.
4. User Content
You retain ownership of drawings you create. If you enable cloud backup, you grant us permission to upload and restore those files to and from your Google Drive solely to provide that feature. We do not claim ownership of your artwork and do not use it to train AI models.
5. CleanSketch Pro
Pro is a one-time in-app purchase billed through Google Play (cleansketch_pro_lifetime). It unlocks an ad-free experience, custom canvas size, and all particle effect brushes. There is no subscription and no auto-renewal. Restore purchases through Google Play on the same account. Refunds follow Google Play policy.
You may also watch a rewarded advertisement to unlock Pro features on that device for one day. That temporary unlock is not a purchase and does not transfer.
6. Ads
Free users may see app-open ads. Rewarded ads are optional and shown only when you choose to watch them for a one-day Pro unlock. Pro users do not see ads.
7. Prohibited Conduct
Do not use the App for illegal activity, or to interfere with the App or its servers.
8. Intellectual Property
The App (excluding your drawings) remains the property of GZLL Studio and its licensors.
9. Disclaimer
The App is provided “AS IS” without warranties of any kind.
10. Limitation of Liability
To the maximum extent permitted by law, GZLL Studio is not liable for indirect, incidental, or consequential damages arising from your use of the App.
11. Changes
We may update these Terms. Material changes will be indicated by updating the date above.
